3.3.X USE (JAXP) v1.1 OR 1.0

[Shawn]

Does anyone know if Tomcat 3.3.x uses JAXP 1.1 or 1.0?

Our open source project needs 1.1 and I need to figure out what I should
be telling people in terms of what works.  3.2.x has 1.0 I believe.

TIA,

TryCatchFianlly requires servlet 2.3?

[Shawn]

Someone told me that since our tags impliment a tryCatchFinally clause,
we need to use servlet2.3.

Is that right?

I though tryCatchFinally was just basic syntax.

Re: Simple question on Unicode URL in Tomcat

[Shawn]

Hiho,

try something like:

String s = URLEncoder.encode(s, enc);

s is your URL and enc is the java encoding such as "Shift_JIS".  See 
URLEncoder for more info.

Will work from java 1.4 I believe.

Had the same problem and this seems to solve it just fine.

RE: Does Tomcat support Unicode URL

[Shawn]

Well Java 1.4 does.

Did you try something like:

<%=URLEncoder.encode(s, enc)%>

s is your URL and enc is the java encoding such as "Shift_JIS".  See 
URLEncoder for more info.

Will work from java 1.4 I believe.

Had the same problem and this seems to solve it just fine.  I had to set 
the correct encoding though. --




We tried to encode the characters with % URL encoding, but seems not 
working.
Can anyone help?
Thanks.
John

System Monitor accuracy

[shawn]

Is it just me or is the System Monitor unreliable.

It shows my cpu at 100% locked there and my system is responding slowly
but viewing it bye the process listing (all, my and/or active) gives me
nothing using the cpu other than the system monitor and netscape at like
1%).  

Under windows at least I could find and shut the culprit down.  It may
well have to do with the ide I'm using to write some java stuff or a web
app that I'm working on but I hate to just have to kill everything
blindly hoping to get working again.

That part worked for me too.  Is there an advantage to breaking your
Context into two pieces.  Anyway, I tried it like that with no problem.

DBCP leak ?

[shawn]

As noted in Tomcat docs,

A web application has to explicetely close ResultSet's, Statement's, and
Connection's.

I am using a web app that opens a ResultSet locally (in a method) but it
never gets closed (gc'd sometime I presume).

Under Oracle, a user is hitting the maximum number of Oracle process and
I presume it is a leak.

Three questions.

1) must a local ResultSet be explicitely closed to avoid a leak

2) if I use, 
  logAbandoned
  true


to log the stack trace, where is that log?  Under logs in the usual place for that 
context.
I have to tell someone else where to find the log otherwise would just look for it 
myself (ie I'm not running Oracle).

3) If only Oracle shows this behavior what could account for that?  Diff jvm?  (just 
curious)

TIA

In most places yes.  Might drivers also close the ResultSet when using a
preparedStatement.

The ps  and connection is always closed.  The ResultSet is closed in
most places (and I'll correct where it's not).

I wonder if the Oracle driver wasn't closing it (not that it should be
expected to) and GC wasn't doing it either, hence the leak.
Anyway, thanks for the help.

Will clean up the few rough spots.

class loading issue bug? fw to dev list?

[shawn]

Using Tomcat 4.1.17 to upload a servlet I get a Class not found error
when the class is there.

If I put the class into jakarta/common/classes it works fine.

Notice that the error stems from my driver in jakarta/common/lib while
the class it can not find is loaded from a jar in my app's WEB-INF/lib

ERROR [Thread-4] (SqlUtil.java:360) - ::logSqlExceptionSQL - exception
> java.sql.SQLException: Class not found:
> java.lang.ClassNotFoundException: org.dbforms.util.FileHolder while

>   at org.dbforms.util.ResultSetVector.(ResultSetVector.java:93)

A FileHolder holds data saved from a
com.oreilly.servlet.multipart.FilePart as byteArray 

I would think this is not by design or it would be documented.

I realize this mail might best go to the developers list but ...what's
that address...I don't subscribe...could someone forward this...

..maybe this has already been solved?!?...

Hello,

Under Tomcat 5.0.18 with servlets compiled with 1.5 beta, I get an odd 
message, and  the servlet won't load.  When the same servlet is compiled 
with 1.4.2 it runs fine.

The method signature in the following message is correct.  There is simple 
nothing to complain about.   Is this a problem with Tomcat or Java 
sdk1.5.  Where is the best place to report this to?

No, I have not altertered my common/endorsed jars

Re: Tomcat w Java1.5 beta problem

[Shawn]

I suggest rebuilding tomcat with 1.5 beta if you want to run servlets
compiled using 1.5 beta.  I'm not even sure my suggestion will work, as
I haven't tried it myself.  There has not been a tomcat release declared
to support JDK 1.5 yet, although you're welcome to do building and
testing for us ;)
The problem I had, I think, is that my method used an Enumeration and 
under 1.5 enum is a new keyword but 
jakarta-tomcat-jasper/jasper2/src/share/org/apache/jasper used enum many 
places as an identifier, as do some classes in  
org.apache.tomcat.util.compat

Re: Unable to use getGeneratedKeys() through dbpc

[shawn]

Thanks for the help Steve,  here is the code that works...

try {

javax.naming.Context ctx = new javax.naming.InitialContext();
javax.sql.DataSource ds = 
(javax.sql.DataSource)ctx.lookup("java:comp/env/jdbc/testDB");
Connection conn = ds.getConnection();


/  
 BEGIN WORKAROUND
org.apache.commons.dbcp.DelegatingStatement dste = 
(org.apache.commons.dbcp.DelegatingStatement)conn.createStatement();
Statement ste = dste.getDelegate();
/  
 END WORKAROUND
ste.execute("INSERT INTO test (name) VALUES ('test name') ");

ResultSet rs = ste.getGeneratedKeys();
rs.next();
out.print(rs.getInt("GENERATED_KEY"));
}
catch ( Exception e  ) {
out.print(e.getMessage());
e.printStackTrace();
}

The root cause is that dbpc's org.apache.commons.dbcp.DelegatingStatement has a 
passthru method for every Statement method as defined by the jdbc2 version of the 
Statement Interface.  
The DelegatingStatement then simply calls the corresponding Statement method i.e.

public int executeUpdate(String sql) throws SQLException { checkOpen(); return 
_stmt.executeUpdate(sql);}

What is needed is the following

public ResultsSet getGeneratedKeys() throws SQLException { checkOpen(); return 
_stmt.getGeneratedKeys();}

Of course the more appropriate way of doing it would be to implement the entire jdbc3 
version of the Statement interface (as well as the other APIs in jdbc).
Perhaps if I get time I will give it a shot

Re: Unable to use getGeneratedKeys() through dbpc

[shawn]

Thanks for the input Steve,

I agree that it SHOULDN'T be dbpc, but it looks as if it is.  
Actually the driver does support it quite nicely.  Everything works great if I create 
my connection manually.  
Things only break if I retrieve the connection from jndi ( and thus dbpc ).

//This can use getGeneratedKeys()
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection conn = 
DriverManager.getConnection("jdbc:mysql://localhost:3306/testDB?user="+dbUser+"&password="+dbPass);

//This cannot..
javax.naming.Context ctx = new javax.naming.InitialContext();
javax.sql.DataSource ds = 
(javax.sql.DataSource)ctx.lookup("java:comp/env/jdbc/testDB");
Connection conn = ds.getConnection();

As things stand now I must either give up connection pooling ( not a good option )  or 
create a workaround through sql ( decreased performance through through additional 
queries ).

Anybody know a way I can have both?

Unable to use getGeneratedKeys() through dbpc

[shawn]

Hi folks,

It seems to me that dbpc does not support getGeneratedKeys().  If I understand 
correctly this is a jdbc v3 call and it is possible that dbpc will not yet support 
jdbc3.
I would appreciate any suggestions on alternative pooling mechanisms that 
could support this (Or any corrections if I am just being dumb).  
I would really rather not rely on queries to retrieve the new key after the 
insert.

Here are the setup details..

RedHat 7.3
Tomcat 4.1.2
MySQL Connector/J 3.0.1

dbpc is working from within JSP, beans and servlets great, but chokes when requesting 
the generated key after an insert.  Here is some code and exceptions


try {
   
//Doing non-pooled connection works
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection conn = 
DriverManager.getConnection("jdbc:mysql://localhost:3306/testDB?user="+dbUser+"&password="+dbPass);
  
/*
//Doing dbpc provided connection throws an exception
javax.naming.Context ctx = new javax.naming.InitialContext();
javax.sql.DataSource ds = 
(javax.sql.DataSource)ctx.lookup("java:comp/env/jdbc/testDB");
Connection conn = ds.getConnection();
*/

Statement ste = conn.createStatement();
ste.execute("INSERT INTO test (name) VALUES ('test name') ");

ResultSet rs = ste.getGeneratedKeys();
rs.next();
out.print(rs.getInt("GENERATED_KEY"));
}
catch ( Exception e  ) {
out.print(e.getMessage());
e.printStackTrace();
}

Re: Apache Index page jsp and sessionid with JKMount *.jsp

Use mod_dir in Apache.  It is standard.

add this directive in you apache conf 
DirectoryIndex index.jsp index.php index.html index.htm 

options are listed in order of preference.
the directive can go in the main conf or in a Vitual Host Container.
See the apache docs for more detail.

If you do not have a core you can do it this way

(gdb) run -X

( cause your app to crash )

jspC precompiling jsp pages

[Shawn]

I noticed an interesting quirk about jspC that I 
just wanted to pass along to novices like myself.  When using the -webinc 
 option with windows, I had to flip the slashes (must 
be it's heritage) around for my servlet to be found.
 
For example the xml file that I was given 
included:
 

 ...
\wiseOwl\JSP.jsp(the\ were 
backslashes
...BUT WHAT WORKED IS AS 
FOLLOWS
 
...
/wiseOwl/JSP.jsp
...
maybe this won't be of use to anyone, but isn't it nice to think that it 
might

Re: Need help identifying the browser a user is using

[Shawn]

I dk if this answers your question but one suggestion I've seen suggests
testing for IE first and the netscape afterward. (from JAVAServer pages
H.Bergsten)
 For example...
<%@ page language="java" contentType="text/html" %>



<% if (request.getHeader("User-Agent").indexOf("MSIE") != -1) { %>
  You're using Internet Explorer.
<%
   } else
 if (request.getHeader("User-Agent").indexOf("Mozilla") != 1) {
%>
  You're using Netscape.
<% } else { %>
  You're using a browser I don't know about.

unable to load javabean with jspc

[Shawn]

I'm trying to precompile a jsp with a bean so that 
I can use it like a servlet, but get a "bean can't be loaded error".  How 
can I adjust things so that jspc can find the bean.
 
Note, if I use the exact same packages and files 
under Forte it works fine and runs.  Also, I've gotten some examples to 
precomile with beans, so maybe it's a matter of putting something in a jar or a 
war file because simply placing the class in the lib or under web-inf/myPackage 
hasn't worked
 
This is pretty important for me to figure out so if 
you have any suggestions, I'd greatly appreciate 
them!!

RE: always getting 403 Forbidden pages

  Usually a directory permission problem.  Do you have the files marked a

directories where you have the files and "chmod 644" on the files.

I keep getting 403 pages when trying to access the test or example jsp's or
servlets.  What can be causing this?

I'm using TC322 on Red Hat 7.1

Java Beans and JSP Question.

[Shawn]

Dear Dan,

I believe I'm familiar with the problem you're having and think it's related to Forte. 
  In my case, either Tomcat or Forte complained about methods that were clearly there. 
 What I've had to do is take my bean and put it in two places.  Within Explorer in 
Forte which shows my filesystems I have 
c:\tomcat\webapps\myApp\WEB-INF\classes\com\koyuru.  I have also had to directly mount 
com\koyuru as a filesystem within Forte as well.  If I modify a bean in one, I must 
copy it to the other, otherwise either Tomcat or Forte will complain.

In my case I was using examples from the jspBook and tried to modify them but Forte 
claimed my new method wasn't there. It didn't seem so related to overloading as much 
as the filesystem.  That shut it up though.

Shawn


I have a standard java bean.  The different thing about it is that I
usually have two overloaded set methods per attribute.  For example,

public class MyBean {
private int a;

public setA (int a) throws Exception {
if (a > 100) throw new Exception ("Must be less than 100");
}

public setA (String a) throws Exception {
try {
setA(Integer.parseInt(a));
} catch (NumberFormat Exception exception) {
throw new Exception ("Format incorrect.");
}
}

//I usually have one getA
public int getA() {
return a;
}
}

Now when I use this bean in a JSP that is stored in the request scope,
at times the compiler will complain that it cannot find a get method for
"A".  Even though one get method for that particular attribute is
clearly there.

Some added information, I use Forte Community Edition 2, and Tomcat.
Forte's compiler complains about one attribute while Tomcat complains
about another completely different attribute it cannot find the get
method for.  Which makes me itch with anger.  The note is my example
above is very simple. I used it just to explain my problem.  My actual
bean has about 17 attributes all with 2 setter methods each and 1 get
method each.

Does anyone know how to resolve this issue?

Thanks for your help.

install probs

[Shawn]

Hello,

I can't get Tomcat up under Win 98.  In my autoexec.bat file that I get to
through the sysedit command I have

C:\>set JAVA_HOME=C:\JDK1.3.1

C:\>set
CLASSPATH=C:\TOMCAT\LIB\SERVLET.JAR;C:\TOMCAT\LIB\JAXP.JAR;C:\TOMCAT\LIB
\ANT.JAR;C:\TOMCAT\LIB\PARSER.JAR;C:\TOMCAT\LIB\WEBSERVER.JAR;C:\TOMCAT\LIB\
JASP
ER.JAR;C:\TOMCAT\CLASSES;C:\JDK1.3.1\LIB\TOOLS.JAR;

C:\>set TOMCAT_HOME=C:\TOMCAT

Then if I try to start Tomcat I get:

C:\tomcat\bin>startup
Out of environment space
Out of environment space
Out of environment space
Out of environment space
Out of environment space
Including all jars in C:\TOMCAT\lib in your CLASSPATH.
Out of environment space
Out of environment space

Using CLASSPATH: C:\TOMCAT\classes

Out of environment space
Starting Tomcat in new window
C:\tomcat\bin>

What can I do short of trying the surely superior RedHat?  I've got it
cooking on Win2k but 98 blah.

Shawn


Note: I left xml.jar out of the class path as there isn't one in the LIB,
but even if I put it in there was the same error.  Do I need to find and use
that Jar?

DBCP trouble in 4.12

[shawn]

Hello,

Not at all sure if this is my own problem or a bigger issue but I moved
from 4.06 to 4.12 recently and...

The example DBCP given for mysql works fine for me with
mysql-connector-java-2.0.14-bin.jar  Thanks for the nice docs!

However, when I move the code to an app I'm trying to move, I get a
"Cannot load JDBC driver class 'null'" error message.  It stems from
Connection conn=dataSource.getConnection();  (see complete snippet
below)

The code was originally in a servlet (and the ds got passed to a bean)
but I moved everything to the bean with the same results.


Connection conn;
// Get the user info from the database
try {
  Context ctx = new InitialContext();
 if(ctx == null ) 
  throw new Exception("Boom - No Context");


DataSource
dataSource2=(DataSource)ctx.lookup("java:comp/env/jdbc/TestDB");
if(dataSource2 == null ) 
  throw new Exception("Boom - No dataSource");
 
  conn = dataSource2.getConnection();
}
catch (Exception e){throw new SQLException("couldn't get conn
from dataSource2 in employeeBean"+e.toString());}

Yes, I recompiled everything after the move and have the driver in the
Catalina_Home/common/lib dir.

TIA,

Shawn

ClassCastException Conn=dataSource.getConnection();

[shawn]

I am getting a java.lang.ClassCastException

from Connection conn = datasource.getConnection();  
in the folowing:

try {
Context ctx = new InitialContext();
if(ctx == null )
{throw new Exception("Boom - No Context");}

   
DataSource
dataSource2=(DataSource)ctx.lookup("java:comp/env/jdbc/");
if(dataSource2 == null )
{throw new Exception("Boom - No dataSource");}

conn = dataSource2.getConnection();
    }

Why would that be?

TIA

PS the ds ="null" error I had earlier was due to not setting up my root

session id's really unique?

[shawn]

If I use RequestDispatcher.forward(request, response) to another context
am I running the risk of session id conflicts?  

I mean if a session Id is given in one context, another context is
restarted and the java.security.SecureRandom is re-initialized for that
webapp, then it would seem possible that newly generated sessions in the
second context could match the previosly generated session id that was
transferred from the first context.

I doubt I know as much as many on this list, but that is something that
I wondered about.

Shawn

PS  I'm relying on potentially outdated info from a list that was posted
in response to this topic.

 yes I did but will the sessions tranfer uniquely?

Re: Mysql driver problem...

I got that same message myself many times.

Are you trying from the root context?

If so, you'll need 
  
DB Connection
jdbc/root
javax.sql.DataSource
Container
  
in web.xml

and 




in server.xml

that's what worked for me anyway

just like the example, I should think that would be ok.

my point was

and not sililar to the following which I found in server.xml

   

 
I tried  
and got the same message you did.

Re: session id's really unique?

[shawn]

Just to confirm,

If I send use RequestDispatcher.forward(request, response) and send it
to another context, that session will be newly managed under the new
context (or by the original context) and therefore there is no risk of
duplicate id's.

The other issue is to be patched.

Shawn

Sorry to be paranoid. Can't help it though.

Re: Cannot load JDBC driver class 'null'

[Shawn]

I had that error too.

In my case it had to do with how I configured web.xml and server.xml.

I was able to get the example from the docs working but when switching to
/root context got mixed up.

You aren't using the root context are you?

In any case, I would double check again server.xml and web.xml and compare
them to the examples.  That's where my driver class 'null' problem arose.

Re: Cannot load JDBC driver class 'null'

[shawn]

I had that error too and just reproduced it again to be sure of how I
resolved it.

Let's say the following is a correct entry in server.xml:



but I make a mistake and use



**Notice the D vs d in the context path**

Then I get a Cannot load JDBC driver class 'null' error message

With the root context, where I had my problem, it was confusing because
I needed path="/root" and not path="/".  Also, the error message is
seemingly unrelated to the actual problem

Anyway, whether or not this is the origin of your error I do not know,
but only know that I got the same message when my context path was
incorrect.

Re: Need help w. servlet mapping tag.

Stab in the dark.

Try taking out the extra spaces in things like

snoop

to be
snoop

Stupid guess.

Hope it doesn't waste your time.

Re: Require a secure connection

[shawn]

According to
http://java.sun.com/j2ee/1.4/docs/tutorial/doc/Security5.html another
way would be to specify it in web.xml. 

... 

If you specify CONFIDENTIAL or INTEGRAL as a security constraint, that
type of security constraint applies to all requests that match the URL
patterns in the Web resource collection, not just to the login dialog.

 Specify CONFIDENTIAL when the application requires that data be
transmitted so as to prevent other entities from observing the contents
of the transmission. Specify INTEGRAL when the application requires that
the data be sent between client and server in such a way that it cannot
be changed in transit. The following example code from a web.xml file
shows this setting in context:


  

  WRCollection
  /index.jsp
  GET


  user


  CONFIDENTIAL

ENCTYPE + SetCharacterEncodingFilter = no go joe for Tomcat 5.0.28

[Shawn]

Hello,

When using ENCTYPE="multipart/form-data" in a form on a jsp page, text
sent ignores the SetCharacterEncodingFilter which is calling
request.setCharacterEncoding("UTF-8");

I thought about getting parameter values by using 

String field = request.getParameter("whatever");
field=new String(field.getBytes
("UTF-8"));

Does this seem a reasonable approach or is should the
SetCharacterEncodingFilter *really* be setting the charEncoding?

I don't want to be creating a new string for every parameter unless
necessary.

When ENCTYPE is not set, all works as expected.

This problem is seen on Tomcat 5.0.28, but not 4.x versions.  I
understand something changed around 5.0.27 for UTF-8 handeling but am
not sure if that is realated.

AW: Tomcat Clusterin Multicast Multiinstances

[Shawn]

Hello,
This thread hijacked the original about Clustering.
For courtesy to others trying to follow the original thread, it would be appreciated 
if you would start an original thread under your topic.
Not only that, but trimming the unneeded context is nice as well.
Please note:  I am not any kind of moderator and my opinion carries no offical weight 
but am a open source developer who does a great deal of work through mailing lists and 
appreciates it when people follow common courtesy.

Can any one quickly tell the comparison of running tomcat as a service or
without a windows service.
I mean what are the benifits of running tomcat as a windows service.

It actually makes since.  Most web servers are in native code which is

Of course not.  I'm only regergitating stuff I have read.  But I have seen

Thanks so very much...  I saw their is a config option in the Jasper to

Shawn,

I ran into this problem as well when switching from 4.0 to 4.1.  I think it
has something to do with 4.1 pooling and re-using tag objects.  What I did
in all of my doStartTag(), doAfterBody(), etc... methods was manually call
release() to reset the data in the tags like so:

public int doStartTag() throws JspException
{
  try
  {
...
  }

  catch (Exception exception)
  {
throw new JspException(exception);
  }

  finally
  {
release();
  }

  return SKIP_BODY;
}

Have a nice day ...

I'm having a problem working with my custom tag library.  The stange part to

has a tage called site that extends a base tag, and those tags use other
classes in my data namespace to hit a database.

The tags are returning the proper data in both versions, but in 4.1.27, I
have to "reload" the contect in the manager for it to "register" the changes
from the database.  I have added some printlns to std out to track what's
going on.  In tomcat 4.0.6 they are going through all the code as I would
exspect it to.  I have included each of the class files that are called.  I
have also included the printouts from both versions of tomcat to clierify
how each version is handling the calls.

The object hiarchey goes as follows:

jPublish.Tags site extends inc_tag.
jPublish.Data.site_manager extends jPublish.Data.manager, managers contain,
load, and fill datas.
jPublish.Data.site_data extends jPublish.Data.data, used for storing data
and tracking updates.

RE: Custom Tag Lib

[Shawn Zernik]

Mr. Mezick:

>From what I'm gathering, the release should not be implimented to reset the
data and classes used by a tag, but only for things like closing files and
db connections? Just to make sure I'm thinking about this properly, the
doStartTag should be treated like the constructor: make sure my data is
setup properly there. The doEndTag should be used for "normal" completion
without errors.

Does Tomcat impliment object pooling beyon the tags?  Are my supporting
classes for the tag pooled?

Thanks to all who have helped me.

It would be best if you went a rewrote your tags not to require release
to be called.  That change will also bring you in-line with the jsp

NetBeans Debug in JSP Tag Files

[Shawn Zernik]

Tomcat-Users:

I have the tag lib working.  Thanks again.

I was wondering if anyone could point me to a good tutorial on how to use
NetBeans with Tomcat that's running.  I can configure tomcat to allow debug
connections and connect using NetBeans, but once I'm online with the server
how do I trace through a JSP page?

I can't resolve that problem.  can I impliment those tags as simple tags:
the JSP spec says that they will not be cached or reused.

Hi Shawn,

Actually, I wasn't aware that there was an option to disable it.  When I
figured out what was happening, I went ahead and handled it in my code.  No
telling how other application servers might handle it.  If you're only going
to be deploying on Tomcat, disabling pooling would probably save you some
time, but you still might want to handle it in your code to get better
performance.

Shawn,

I ran into this problem as well when switching from 4.0 to 4.1.  I think it
has something to do with 4.1 pooling and re-using tag objects.  What I did
in all of my doStartTag(), doAfterBody(), etc... methods was manually call
release() to reset the data in the tags like so:

public int doStartTag() throws JspException
{
  try
  {
...
  }

  catch (Exception exception)
  {
throw new JspException(exception);
  }

  finally
  {
release();
  }

  return SKIP_BODY;
}

I came across what appears to be a security hole when running tomcat.
I'm not sure how widespread it is, but my linux server is safe, yet my
windows XP, tomcat 4.1.24 is vulnerable.

I found that if you append %20 to a jsp page it shows the source code
instead of displaying the page:

http://192.168.1.54:8080/index.jsp  
http://192.168.1.54:8080/index.jsp%20 

So how widespread is this?

monopolization (sorry, kind of prejudice). However, I notice that more and
more people pick up C#/.NET due to their new advantages. I also heard that
C# is much faster than Java. My concern is, can Java/JSP still be
competitive to Microsoft's products? I don't like to see java be beaten by
Microsoft since it borrowed so many ideas from java to make up the so-called
"C#".

ok, feel free to talk about this topic.

RE: Simple question about JSP page

[Shawn Zernik]

you should post you tag code of the code for that page.  It can either be a
problem with your tag, or the connection pooling.  Try stopping and
restarting the app in the manager and see if that makes the updates take
affect.  If so, the issues is with re-use of objects and possible connection
pooling.

Hi,
Maybe it's a stupid question.
Built jsps for adding&searching with MySQL. First listing all existing
records in db and then adding a new one into database, then listing all
records again. Now the list is the same as previous.
How to solve it?

tomcat jk1.2 connector and IIS logging

[Shawn Swistak]

Hello,
 
I am using Tomcat-4.1.29 and the jk1.2 connector  (isapi_redirect.dll)
to interface with IIS 6.
 
Everything works wonderfully, except that IIS logs the cs-uri-stem as
the redirect dll (/jakarta/isapi_redirect.dl).  Is it possible to log
the actual redirected URL (i.e index.jsp)?  Without the actual URL the
IIS logs are pretty much useless.
 
Current Log Entry:
*
2004-03-29 00:12:53 555.55.55.555- GET /jakarta/isapi_redirect.dll - 200

mod_jk hangs

[Shawn Wilson]

Just yesterday we started running into problems requesting pages on our 
production website through mod_jk. Previously everything had been 
working fine for months. Essentially what happens is when you request 
the page for the first time (doesn't seem to matter what browser you're 
using) the browser just sits and spins. Then after hitting refresh 
(Ctrl+R) a couple times it finally comes up. Subsequent visits to the 
same page continue to work for me in Mozilla but after closing IE and 
reopening it after a couple more requests it hangs again. In case it 
helps, the site in question is http://www.atmreports.com.

I simply cannot figure out what is going on. I do see many errors in the 
mod_jk.log, but these had been there before when everything worked fine too:

[Wed May 05 09:27:46 2004]  [jk_ajp_common.c (1137)]: Error reading 
reply from tomcat. Tomcat is down or network problems.
[Wed May 05 09:27:46 2004]  [jk_ajp_common.c (1290)]: ERROR: Receiving 
from tomcat failed, recoverable operation. err=0
[Wed May 05 09:27:46 2004]  [jk_ajp_common.c (1309)]: sending request to 
tomcat failed in send loop. err=0
[Wed May 05 09:27:46 2004]  [jk_ajp_common.c (738)]: ERROR: can't 
receive the response message from tomcat, network problems or tomcat is 
down. err=-1

A few things to note, any of which may contribute to the problem but for 
the life of me I can't figure out how:

1. On Friday we just moved out datacenter to a new location. However we 
see this problem even internally at the location so I don't believe it 
is any sort of routing issue (and the problem didn't start until Tuesday).

2. The clock on this webserver was many hours off. On Tuesday (yes, the 
day the problems started) the clock was synchronized and the timezone 
correctly set so the machine now has correct time. This seems to be the 
most probable cause simply because it happened around the same time, but 
I just can't understand why or how.

3. Yesterday we rebooted the box to see if that would help. It did. We 
didn't have any more problems at all that day until this morning we see 
the problems again. Today we recycled just tomcat and that seems to have 
fixed it as well, though I expect that by tomorrow I will see the 
problem again.

4. I wouldn't think this could have anything to do with that new Sasser 
worm, but listing that just in case.

The machine is running Linux kernel 2.4.20-8 with httpd-2.0.40-21 and 
jakarta-tomcat-5.0.18. We are running 4 instances of tomcat on the box, 
each started with the following JVM options:

   -Xmn128M -Xmx1024M -Djava.awt.headless=true

Nothing having to do with configuration has changed at all in a long 
time. Here is the relevant configuration sections:

# Mod_jk (Tomcat connector)
LoadModule jk_module modules/mod_jk.so

JkWorkersFile /etc/httpd/conf/workers.properties

...and later (in a  section)...

Okay, here is the section from our server.xml in production:

  




  
  
  

  
I thought it interesting the comment that "this is here for

required if I want AJP/1.3 isn't it? I can't remember if that comment 
was there or if I (mistakingly) added it. Anyways, I see that I could 
probably do well to add the minSpareThreads and maxSpareThreads 
parameters. Any idea where I should look in my httpd.conf file to see 
what values to set these to?

So you might want to increase min and max spare threads to accomodate

Re: mod_jk hangs

[Shawn Wilson]

Looks like the maximum for everyting in my config was 150 so I'll try 
setting maxSpareThreads for Tomcat to 150 as well. If this is indeed the 
cause of the problem, any idea why it would just start happening 
yesterday after months without problem? My only guess is that perhaps we 
just happened to reach some threshold of traffic yesterday that we never 
did before. Actually, that may indeed be the case since we usually get a 
surge of traffic during the beginning of a month.

Well, that depends on what platform and how apache was compiled.  As I

If you are using windows XP you are better off setting the port with the

Thanks... I know what a firewall is and what it does.
Problem is, with the free version of ZoneAlarm you
cannot manually specify ports to allow access on. I

I need the firewall. It is my home PC on a ADSL

I use it for basicly everything I do on the internet.

RE: MOD JK NOT SUCESSFUL

[Shawn Zernik]

Hey:

After playing with it for some time, I found the following VERY useful
(http://www.gregoire.org/howto/Apache2_Jk2_TC4.1.x_JSDK1.4.x.html).  It's
probably a run of the mill solution, but I'm not complaining for development
perposes.  I followed these directions and am using Tomcat throug socks, not
JNI. That means tomcat needs to be running, and your workers2.properties
would look something like this:

=

[logger]
level=DEBUG

[config:]
file=c:/Apache2/conf/workers2.properties
debug=0
debugEnv=0

[uriMap:]
info=Maps the requests. Options: debug
debug=0

[shm:]
info=Scoreboard. Required for reconfiguration and status with multiprocess
servers
file=c:/apache2/logs/jk2.shm
size=1048576
debug=0
disabled=0

[workerEnv:]
info=Global server options
timing=1
debug=0

[channel.socket:localhost:8009]
info=Ajp13 forwarding over socket
debug=0
tomcatId=localhost:8009

[status:]
info=Status worker, displays runtime informations

[uri:/jkstatus/*]
info=Display status information and checks the config file for changes.
group=status:

[uri:/jsp-examples/*]
context=/jsp-examples
debug=0

[uri:/admin/*]
context=/admin
debug=0

[uri:/manager/*]
context=/manager
debug=0



Every thing else should work just as their directions state.  I'm using
Tomcat5 and Apache2 on XP.  If I try to do the JNI method, I run into hords
of Java errors that are very discouraging and don't speak for managability
of Java: sorry, I'm a little jaded on java right this moment.  Maybe when I
start programming my oppinion will change.

Vishal:

go through the batch file (.bat) and add PAUSE followed by and enter after
the tomcat or java command to see their responces.  Batch filesare just a
series of DOS command made to run in order.  It has a GOTO statments and
enviorment vars for varibles.  The %1 %2 %3 represent the first command line
argument, the soncond, and the third.  It has if statments.  Just follow it
throug and add some pauses, that'll cuase it to wiat for you to press a key
alowing you to see the error messages.

The second command prompt window is called through the first batch fil
through the CMD command.  Look for the CMD or other betch files and add
pauses to those files.  It's calling another command prompt to free the one
you in when Tomcat starts.  This second command prompt is probably giving an
error like "Port already in use" or something else.  Adding the pause will
allow you to see these errors.

I work for a small company which is seriously considering the .NET route

Re: Admin Webapp Problems (WAS: MBean server?)

[Shawn Wilson]

Okay, this was just dumb on my part. When I installed Tomcat I installed 
the tomcat-noexamples and tomcat-admin RPM's. However, I noticed that 
installing Tomcat on a different machine (with examples), the first 
section in the server.xml file having to do with (believe it or not!) 
MBean server was not commented out like it was in the noexamples 
server.xml file. So basically that's all the problem was... if I had 
looked at server.xml more closely sooner I could have saved myself lots 
of frustration!

Thanks for all the help,

Hi Shawn,

I'd recommend installing the full non-RPM version that includes all necessary
jars.  In that version, you will see the following files in
common/endorsed:

xercesImpl.jar
xmlParserAPIs.jar

What Bill says it correct, though.  The Xerces version that come with
Tomcat causes problems with Struts apps because of an XML parsing bug
in Xerces which was recently fixed.  You can either do as he says and
go back to using 2.1.0 version or move to the latest jars which
contain the fix:
http://gump.covalent.net/jars/latest/xml-xerces2/


Otherwise, you could also check the xml commons to grab a
xml-commons-api's jar that contains an earlier version of the xerces
packages equivalent to the 2.1.0 release.

Removing files from /lib

[Shawn Wilson]

I must not be understanding completely the way the classloaders work under
Tomcat. I thought that if I stop a webapp through the manager application
that should unload its jar files. However, even after it's stopped, I find
that log4j jar file is locked so I can't remove it.

Why would that one file be locked but the others not?

Announcement: JSP Standard Tag Library (JSTL)

[Shawn Bayern]

Tomcat users,

You might have heard about the JSP Standard Tag Library (JSTL), which is a
new standard under the Java Community Process.  JSTL 1.0 was finalized at
the end of May 2002, and its reference implementation was released as part
of Sun's Web Services Developer Pack (WDSP) earlier this month.

The goal of JSTL 1.0 is to simplify the development of JSP pages by
standardizing tags for the following tasks:

   - control flow (iteration, conditional logic, and error handling)
   - URL management (session encoding, cross-context imports, etc.)
   - text formatting and internationalization (i18n)
   - XML manipulation (with XPath)
   - database access (via JDBC)

JSTL also offers an expression language for accessing scoped attributes,
request parameters, and other data.  (This expression language is planned
to be the basis of a core addition to JSP 2.0.)  Using JSTL tags and the
new expression language, you can often avoid scripting elements
("scriptlets" and scripting expressions) in your pages.

JSTL works with a number of different models for web development.  Users
of a "model 2" approach will probably appreciate JSTL's expression
language and core tags for control flow; prototypers and developers of
small applications may appreciate its SQL tags.  Personally, I find JSTL's
XML tags to offer a convenient, powerful alternative to XSLT for many
common XML-manipulation tasks.  And JSTL also offers an API for
programmers who wish to configure JSTL and expose data for their JSP
pages.

I'm sending this message to announce that Jakarta Taglibs has just
released version 1.0 of its "Standard Taglib," an implementation of JSTL.
(The implementation at Jakarta Taglibs is also the basis for Sun's
reference implementation of JSTL.)  You can download the 1.0 release of
the Standard Taglib at

   http://jakarta.apache.org/builds/jakarta-taglibs/releases/standard/

The Standard Taglib requires JSP 1.2; it has been tested with Tomcat
4.0.4.  (Earlier versions of Tomcat may have trouble loading the JAXP 1.2
classes included with our distribution, so I recommend using Tomcat 4.0.4.  
A set of older XML files is available from the URL above if you want to
use an older version of Tomcat.)

I'm happy to answer questions that you have about JSTL; for detailed
discussion, you might be interested in joining the 'taglibs-user' mailing
list at Jakarta; see

http://jakarta.apache.org/site/mail.html

for instructions on how to do so.

For general information about JSTL, as well as a link to the formal
specification, pointers to upcoming books on JSTL, and current articles,
see

http://java.sun.com/products/jsp/jstl/

If you have any comments for future versions of JSTL, you can submit them
to our expert group by mailing [EMAIL PROTECTED]

Enjoy,

Migration from 3.3a to 4.0.4

[Shawn Church]

I am new to Tomcat 4, and I am trying to move an existing webapp from 3.3a to 4.0.4.  
I am using Apache as the web server, but I am not quite clear on which portions of 
Tomcat relate specifically to the stand-alone web server configuration versus general 
webapp serving through a connector (Warp or AJP).  For example, the Host container is 
used to define virtual hosts, but is this necessary if Apache is handling the virtual 
hosting?

Any general comparison or migration steps of Tomcat 3.3 to Tomcat 4 would be helpful.  
Currently I have multiple Apache virtual hosts served by multiple Tomcat instances 
(with multiple server.xml, etc.) and everything works fine (in 3.3a).  

Thanks,
Shawn

[Fwd: Enhydra: Enhydra Enterprise Beta 1 Milestone]

[Shawn McMurdo]

FYI, Enhydra Enterprise embeds Tomcat 3.2.1 as it's Servlet
and JSP engine.
Tomcat is the "best of breed" open source servlet engine with
some great developers working on it.
Shawn

Shawn McMurdo  mailto:[EMAIL PROTECTED]
Lutris Technologieshttp://www.lutris.com
Enhydra.Orghttp://www.enhydra.org




We are happy to announce the first beta milestone release of Enhydra
Enterprise (EE). The prebuilt package is available immediately from
http://enterprise.enhydra.org/software/downloads/index.html We encourage
evaluators and developers using 'alpha' versions to change to this version.

Enhydra Enterprise represents the next generation of application server. It
is structured as an "operating system of the Internet," with a kernel that
provides some essential facilities and a mechanism for selecting additional
services to provide configurable platform functionality. We call the overall
structure the Enhydra Services Architecture (ESA). ESA services can be
deployed at runtime, and started on demand. This allows the deployer to
choose just the services required for a particular deployment, and supports
runtime upgrading of services. We aim to offer a trading post for ESA
services, and we encourage the contribution of services to the community.

In this milestone build we have aggregated a set of API-implementing
services on top of the J2SE 1.3 platform, providing many of those APIs
required by the J2EE[TM] specification: Servlet 2.2, JSP[TM] 1.1, EJB[TM]
1.1, JNDI[TM] 1.2, JDBC[TM] 2.0 with optional package, JTA[TM] 1.0.1. The
configuration includes other APIs, as well as services for deployment,
service initialization, and versioned library support. This sample
configuration lets you write portable enterprise-scale applications.

You can imagine many different configurations and platforms being built on
the Enhydra Enterprise project modular architecture. For example, one
collection of ESA services might be equivalent to Enhydra 3.x today (perhaps
JNDI, JDBC, and Servlet/JSP Container). Another collection of services might
be a communications server (perhaps JNDI, SOAP, BXXP, XML/RPC, etc).
Finally, yet another might be a messaging server (perhaps JNDI, JMS, etc).
When you add a new service to the EE platofrm, that new service can be
available to some or all of the applications running on the platform;
visibility is under your per-application control. We hope that the ability
to create new cross-application services will allow for us all to benefit
from radical customization of the concept of what an application server is
and can be.

What It Does:

The beta 1 configuration of EE provides services and APIs needed by
web-interfaced applications (as described abAlso, tve). It can be run on a
range of deployment configurations, from standalone laptop to multi-tier
multi-machine setups. It includes its own web server, or it can be connected
to a third-party web server front end. EE also includes the complete Enhydra
Application Framework from previous Enhydra versions (most recently Enhydra
3.1); the XMLC ver 2.0 tool for separating web page presentation design from
dynamic data programming; and the Kelp toolset for building applications in
third-party IDEs. There are several examples included showing how to run
J2EE-style applications (including Sun's PetStore demo app) and how to write
your own services. We have run this configuration on Windows NT/2000, RedHat
Linux 6.1, and Solaris 2.7.

The server maintains all configuration information directly in a persistent
JNDI namespace for unified management and rapid system restart. Server
management is provided through JMX-compatible MBeans, exposed through the
Enhydra Web Console. This release begins integration of the Enhydra
Authorization and Authentication Library (EAAL) which will provide JAAS-like
security throughout the server, even when we incorporate J2SE1.2 support.

What It Doesn't Do Yet:

Some of the EE Alpha 4 codebase has not yet been ported to the new ESA-based
server: most importantly, JMS is not yet available. The J2EE API set is not
yet complete. Some capabilities are only partially implemented (in the
security work, for example, permission checking is only partially
implemented, we need more LoginModules, and the toolset is not yet started).
We need to complete the J2EE set of capabilities as a proof of adequacy of
the server, and add more samples as proof of flexibility. Specific current
versions and limitations are listed in the Release Notes, and should be
reflected in the ongoing TODO.txt list.

What You Can Do:

We hope the Enhydra community will lend a hand in shaking down and building
up the new server; there is room for contribution in every part of the
effort. As you begin to use the server, please note bugs and what needs to
be made better, and tell us on the mailto:[EMAIL PROTECTED] mail
list - or fix it yourself (see the various Working Groups to d

IIS/Tomcat - Error: The specified module could not be found.

[Shawn Lindstrom]

Hello,

I'm a newcomer to Tomcat.  I have installed v3.3a on Win2k w/ the
isapi_redirect.dll.  I have followed the IIS HowTo to the letter.

I have the green up arrow indicating the filter is working, but something
must be amiss elsewhere and I'm at wits end -- I'm sure it's something
simple and I apologize if this has been answered here before.

Any ideas?

Thanks!
Shawn

Tomcat port 8080, Apache port 80, jsp?

[Shawn Evans]

Here is a simple question... how do I get apache on port 80 to send jsp
requests to the Tomcat server and respond back on port 80.  The reason why I
want to do this is becuase where I work, all ports are blocked except port
80, but I have an applet that needs to get data from the jsp pages.

Shawn

Re: Tomcat port 8080, Apache port 80, jsp?

[Shawn Evans]

I am running the latest 4.0(7) and I cannot find the DLL for it.  Does
anyone know where I can d-load one... I know I know NT, but my office is
buying me a new Linux server.

Re: Tomcat port 8080, Apache port 80, jsp?

[Shawn Evans]

   I read "Installing mod_webapp and using it with Apache 1.3" written by
you, and I have been unsuccessful in getting it to work.  Here is my
configuration:

Win NT4.0 sp6
Apache 1.3.20 d:\webserver\Apache
Tomcat 4.0.7b d:\webserver\Tomcat-4.0.7

   First, I copied 'mod_webapp.so' and 'libapr.dll' to my apache\modules,
then I added this to my httpd.conf

[...]
#AddModule mod_actions.c mod_setenvif.c mod_isapi.c
AddModule mod_webapp.c
[...]
#LoadModule usertrack_module modules/mod_usertrack.so
LoadModule webapp_module modules/mod_webapp.so
[...]
WebAppConnection conn warp localhost:8008
WebAppDeploy examples conn  /examples
WebAppInfo /webapp-info
[...]

   I kick Apache off as a service (Tomcat is already running as a service)
and here is the error that I get "Error 2140:An internal Windows NT error
occurred"... I am able to run Tomcat 4.0.7 as a service without Apache...
and Apache runs fine when I comment out the 5 lines I added above, but I
need to get them working in sequence with one another.

mod_webapp --> NT4, Tomcat 4.0.7, Apache 1.3.20, JDK 1.3.1

[Shawn Evans]

   I read "Installing mod_webapp and using it with Apache 1.3" written in
mod_webapp, and I have been unsuccessful in getting it to work.  Here is my
configuration:

Win NT4.0 sp6
Apache 1.3.20 d:\webserver\Apache
Tomcat 4.0.7b d:\webserver\Tomcat-4.0.7

   First, I copied 'mod_webapp.so' and 'libapr.dll' to my apache\modules,
then I added this to my httpd.conf

[...]
#AddModule mod_actions.c mod_setenvif.c mod_isapi.c
AddModule mod_webapp.c
[...]
#LoadModule usertrack_module modules/mod_usertrack.so
LoadModule webapp_module modules/mod_webapp.so
[...]
WebAppConnection conn warp localhost:8008
WebAppDeploy examples conn  /examples
WebAppInfo /webapp-info
[...]

   I kick Apache off as a service (Tomcat is already running as a service)
and here is the error that I get "Error 2140:An internal Windows NT error
occurred"... I am able to run Tomcat 4.0.7 as a service without Apache...
and Apache runs fine when I comment out the 5 lines I added above, but I
need to get them working in sequence with one another.

   Plus, there are no error messages in the log files.

Working: mod_webapp --> NT4, Tomcat 4.0.7, Apache 1.3.20, JDK 1.3.1

[Shawn Evans]

Sorry if it seems as if I reposted it, I was having trouble with the office
machine, so I sent it out under a new subject, since it was different than
the one I posted before...

when I ran Apache from the command line with the webapp modified conf here
is what I get.

D:\webserver\Apache>Apache
Syntax error on line 176 of d:/webserver/apache/conf/httpd.conf:
Cannot add module via name 'mod_webapp.c': not in list of loaded modules

took that line out and it works... I can see webapp-info and

"IT WORKS" ...

INSTALL.txt

[..]

*-
Another note for Windows: copy also the "libapr.dll" file with the module,
or
your Apache 1.3 web server will refuse to start reporting that the WebApp
module cannot be loaded.

Once you have done that, edit your "httpd.conf" configuration file and
add a few lines to load that module at startup (Windows users, read above,
you have to "replace" libexec with "modules" - I'm paranoid, sorry):

LoadModule webapp_module libexec/mod_webapp.so
and
AddModule mod_webapp.c [ DO NOT ADD THIS TO WINDOWS ]

-*

Thanks for the help

Shawn

mod_webapp performace issues... NT4, Apache 1.3.20, Tomcat 4.0.7, JDK 1.3.1

[Shawn Evans]

Since I finally got the mod_webapp working, I have been banging on the
machine.  Tomcat is solid when I access it from port 8080, and Apache
screams like it should... but
when I access Tomcat thru mod_webapp (examples) I get random errors and even
hello world doesn't work... sometimes

I have a connectionpool bean that I am using in myapp.  I added
connectionpool.jar to /lib.

I added this to the beginning of my jsp.


Here is what I get when I access it... any ideas what I have done wrong?

Re: Tomcat 4.0.7b and lib help (FIXED)

[Shawn Evans]

I don't know about everyone else, but I got my Oracle classes12.zip in my
lib and it wouldn't work so after looking at my code, wondering what I
messed up (4 hours), I decided to change it to *.jar.  OMG it decided to
work... might want to have TomCat be able to do both zip & jar's in the
lib

just my 2 cents.

Understand I am an idiot... but oh well... just a suggestion then for people
like me that read... in Developing Applications with Tomcat, in 4.1
Directory Structure... in the lib/ portions, just put a note... 'JAR's only
(No zips)'... I know it says 'JAR files' but I thought zips and jars were
interchangeable... :-)

RE: Help Preventing VM & Tomcat Crash

[Shawn Church]

Looks like you are using the JDBC-ODBC bridge (maybe to an MS Access or MS
SQL Server database?), which is not thread-safe and is not intended for use
in production environments.  My guess is that one thread (the current thread
servicing the Thumbnail servlet) has a db connection open, and the next
request (the user clicking the thumbnail) opens another db connection.  This
guess is based on these lines in your exception:

An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : unknown exception code occurred at PC=0x77fb16cc
Function name=RtlTraceDatabaseEnumerate
Library=C:\WINNT\System32\ntdll.dll

If this is the case, try finding a pure Java (type 4) JDBC driver for your
database.

I'm working on a servlet that shrinks JPEG photos on the fly to create
thumbnails.  When the user selects the thumbnail page, a JSP generates HTML
that results in many calls to the thumbnail servlet.  If the user is
patient and waits for all of the thumbnails to load, everything works great
-- they can click on a thumbnail to see the full-size version of that
JPEG.  However, if the use clicks on a photo while they are still loading,
I get the exception dump and crash shown at the bottom.  Any help greatly
appreciated!  Regards, Kennedy

Here is my thumbnail servlet:

RE: Help Preventing VM & Tomcat Crash

[Shawn Church]

So much for that theory.

However, your guess is pretty close.  I found something which you might find
interesting.  This is a known bug, which you can check out here:

http://developer.java.sun.com/developer/bugParade/bugs/4502892.html

The problem occurs when the socket is prematurely closed.  The workaround is
to buffer the output via ByteArrayOutputStream, isolating the native method
from stream disconnections.

The evaluation of the bug I will include here for convenience:

***
The JPEG library is not MT-safe.  In particular, there is a definition of
a global variable "struct error_mgr ek_err" which is used by all threads
for error handling -- including a setjmp buffer.  Consequently, when an
error does occur while more than one thread is executing in the native
library, it is common for that thread to longjmp to another thread's state.
It then uses the wrong JNIEnv pointer and trashes the VM.
x@x 2001-10-09

This bug has indeed been fixed in merlin-rc1, but its associated regression
test
(JPEGMultithread.java) is confusing and potentially misleading.  This is
addressed by another bug (4546112 - Reg-test JPEGMultithread.java Failing).
The regression test currently throws exceptions endlessly if bug 4502892 is
not
present, and hangs or crashes the VM if bug 4502892 is present.  This is bad
behavior for a regression test, so it will be updated in accordance with
4546112.
x@x 2001-12-19
***

Hope this helps more,
Shawn

Hi Shawn,

Many thanks for the note & the suggestion!  I am using MySQL as my Db and
MM.MySQL is my driver (mm.mysql-2.0.11-bin.jar).  Given that this is a Type
4 driver, I don't think I should be getting a native code crash involving
database access, right?

I could be missing something, but it seems that the
sun.awt.image.codec.JPEGImageEncoderImpl.writeJPEGStream() method (which is
native code) is trying to write to my output stream and running into
trouble.  I assume this is because the user has clicked on an image serving
as a link to another web page and now Tomcat is off trying to handle the
new page.  My best guess is that in the process of doing so, the output
streams used by writeJPEGStream() are being torn down, but the native code
doesn't know this and it's causing the VM to puke.  Does anyone think my
logic makes sense?  Better yet, does anyone know a way to prevent it? :-)

Regards, Kennedy

RE: Help Preventing VM & Tomcat Crash

[Shawn Church]

One more thing.  There is a fix in jdk1.4.0 which addresses this problem,
where the native code exception is handled correctly.  With this version,
the IOExceptions may be caught and treated as normal behavior.

Here's the fix:

So much for that theory.

However, your guess is pretty close.  I found something which you might find
interesting.  This is a known bug, which you can check out here:

http://developer.java.sun.com/developer/bugParade/bugs/4502892.html

The problem occurs when the socket is prematurely closed.  The workaround is
to buffer the output via ByteArrayOutputStream, isolating the native method
from stream disconnections.

The evaluation of the bug I will include here for convenience:

***
The JPEG library is not MT-safe.  In particular, there is a definition of
a global variable "struct error_mgr ek_err" which is used by all threads
for error handling -- including a setjmp buffer.  Consequently, when an
error does occur while more than one thread is executing in the native
library, it is common for that thread to longjmp to another thread's state.
It then uses the wrong JNIEnv pointer and trashes the VM.

This bug has indeed been fixed in merlin-rc1, but its associated regression
test
(JPEGMultithread.java) is confusing and potentially misleading.  This is
addressed by another bug (4546112 - Reg-test JPEGMultithread.java Failing).
The regression test currently throws exceptions endlessly if bug 4502892 is
not
present, and hangs or crashes the VM if bug 4502892 is present.  This is bad
behavior for a regression test, so it will be updated in accordance with
4546112.

Hope this helps more,

Hi Shawn,

Many thanks for the note & the suggestion!  I am using MySQL as my Db and
MM.MySQL is my driver (mm.mysql-2.0.11-bin.jar).  Given that this is a Type
4 driver, I don't think I should be getting a native code crash involving
database access, right?

I could be missing something, but it seems that the
sun.awt.image.codec.JPEGImageEncoderImpl.writeJPEGStream() method (which is
native code) is trying to write to my output stream and running into
trouble.  I assume this is because the user has clicked on an image serving
as a link to another web page and now Tomcat is off trying to handle the
new page.  My best guess is that in the process of doing so, the output
streams used by writeJPEGStream() are being torn down, but the native code
doesn't know this and it's causing the VM to puke.  Does anyone think my
logic makes sense?  Better yet, does anyone know a way to prevent it? :-)

Regards, Kennedy
