RE: Servlet thread safety in Tomcat

[Yu, Albert]

If you implement the SingleThreadModel interface for your Servlet class,
TomCat will create a new instance for each request.

But if  I am to synchronise my code blocks won't that slow done the 
application, or is there a mode that you can put Tomcat into so that 
it will create a new instance
servlet thread  with its own variables and execution space and stuff 
like that .Because I was thinking  putting all those synchronized blocks 
will slow down the app.

Your primary mistake seems to be in assuming that Tomcat will create a
new instance of a servlet for every thread started. This is not what
happens, therefore servlet instance variables are not thread safe
unless you take additional actions to make them safe. Likewise,
application global entities, such as singletons, won't be thread safe
without taking additional actions on your part. The short rule is
simply if two threads might access this data concurrently, then you
need to protect yourself from such a collision. About the only thing
that is mostly thread safe are objects whose scope is limited to a
single method, but even these can get you in trouble if you put
references to those objects in global locations (such as an application
wide cache).

I realise part of my mistake is using global variables

thread model.
My initial thought ( :-)  forgive me its some time since I have coded

servlets) was that Tomcat will create a new servlet instance that is 
totally independed of the other,  for each request.On testing the app
on 
two client machines I have realized that the data is corrupted all
mixed 
up and my velocity template is throwing an error  caused by
concurrent 
modification.
My question is there some way of making this app thread safe and also

how does Tomcat  actually many requests , in terms of the  threading 
method used?I am using Tomcat 4.1

Hi All
I am developing an application that uses JavaMail.What I am

how Tomcat handles request and issues those request ,this is in

Disabling JSP execution under certain dirs

[Albert Moliner]

Hello.

I've searched the archives on this subject, but the nearest I've reached has
been some posts about not serving static content. It's a bit of a surprise that
no one has asked this before, so sorry if it is a recurrent question.

I want Tomcat (4) to execute JSPs as usual, but prevent it from running the
files that are under a certain directory for security reasons. These files can
be published by external people and are supposed to be static, but if some
mischievous publisher posts a JSP and it is executed then there can be havoc.

Apart from preventing the publishing of files with that extension, is there a
possible configuration that can be set up?

I've tried mapping requests to that dir to the default servlet in web.xml, but
404 errors are returned (why??), and some other wierd things like using an
intermediate servlet that forwards to the default servlet through its named
request dispatcher (the forward method does not seem to do anything when using
the dault servlet, while any other seems to work) or setting up a separate
context for that dir and forward requests to the context, which maps *.jsp to
the default context (I'll skip the details), but I can't find the solution...

What astonishes me more is that forwarding or mapping to the default servlet
does not work, but anyway I must be doing something wrong...

Thank you very much,

Albert.

Re: Disabling JSP execution under certain dirs

[Albert Moliner]

Finally I'll add the restriction on publication, but anyway it would nice to
know whether there's a solution to prevent the JSP from being served (yes,
retrieving an error message or just returning the JSP contents without executing
the class would be alright), at least for the sake of knowing.

The only problem with your alternative is that the mapping is not valid: Perhaps
Tomcat accepts it (I don't think so, as manymonths ago I tried similar mappings
and did not succeed), but anyway the servlet specs only regard four types of
mapping:
- exact path,
- directory (/foo/bar/*),
- extension (*.jsp),
- default(/).
I don't know why (performance?), but there's no place for things like
/whatever/*.ext.

About Tim's answer, there are some things that I don't see clear, basically
dealing with the default servlet. The default servlet is after all a servlet, so
it ought to be forwardable (something to do with having it defined in the
general web.xml and the forwarder servlet in the app's?). Anyway, the security
constraint seems the best approach. I'll look up the security documentation.

Thank you very much (though alternatives are still welcome, as I said before).

Albert.

It sounds like Albert wants certain (static) files to be viewable.
He just doesn't want anyone to be able to execute JSPs from this directory.

One thing you could try is a servlet mapping that sends all requests ending in
that directory that end with .jsp to a servlet that sends back a message
(FORBIDDEN FILE).

  servlet-mapping
servlet-nameForbiddenFileServlet/servlet-name
url-pattern/DIRECTORY_NAME/*.jsp/url-pattern
  /servlet-mapping

 Ideally, files you don't want to be seen should be placed in WEB-INF.

 An alternative is to use a security constraint on the directory that has
 all of the content. This can be done in apache too via the Location
 directive.

 Another way is to place all those JSP's with a different extension and then
 add the mapping to web.xml. Then add the security contraint for that file
 extension. (Or let apache disallow that file extension)

 Forwarding to the default servelt WILL provide a 404 because it is a 404.
 The default servlet gets any request not assigned to any other servlet. So
 if the default servlet find the resource, it returns a 404.

Re: Disabling JSP execution under certain dirs

[Albert Moliner]

Touché.
I don't know why I had not thought of filters for this...

Oh, yes, now I know:
My initial intention was to return the JSP file contents as if it were a .txt
file, and though ServletContext.getResourceAsStream could be used, it involved
having to implement the same behaviour as the default servlet does (last
modified checks, etc.). So after all I wanted the default servlet to serve the
request, and the filter would have needed the same behaviour as the forwarding
servlet I had implemented.

Therefore, my question now becomes: If I needed the default servlet (or the jsp
servlet, as it seems to have the same problems) to serve all requests inside a
subdirectory, or perhaps just some files with a pattern under a subdir, how
should I proceed?

In other words: What's wrong with doing (don't consider code quality, it's just
to show the procedure)


RequestDispatcher defaultDispatcher =
getServletContext().getNamedDispatcher(default);
defaultDispatcher.forward(request, response);


? Why doesn't it work (and jsp doesn't, either), while any other servlet name
just seems to work fine?

Or, otherwise, in the app's web.xml,


servlet-mapping
servlet-namedefault/servlet-name
url-pattern/foo/bar/*/url-pattern
/servlet-mapping


? Amazingly,


servlet-mapping
servlet-namedefault/servlet-name
url-pattern/foo/bar/file.jsp/url-pattern
/servlet-mapping


does seem to work, while not the /foo/bar/* mapping (and this mapping works
with any other servlet name defined in the same web.xml file).

Is it that today it's a Friday? Am I misunderstanding something very basic? Is
this a common behaviour, or just happens in Tomcat (4.1.something)?

Thanks,
Albert.

 Yes, Unfortunately, I bounced off this as well, it would have behooved
 the Servlet API developers to allow URL Rewrites to be a little more
 powerful from a REGEXP standpoint. Look at the j2sdk1.4 api, we now have
 regexp's available there default. One would suspect that the Servlet API
 could easily start allowing more complex regexp into these entries.

 I would recommend writing a Filter that gets run prior to all jsp's and
 applying your own regexp/forwarding to the jsp's when you deem it
 appropriate. This requires j2sdk 1.4 and is pseudo code.


 public final class BlockJspFilter implements Filter {

 String regexp = *.(/foo/bar.jsp|/bim/bam.jsp).*;

 public void doFilter(ServletRequest request,
ServletResponse response, FilterChain chain)
throws IOException, ServletException {

if(request.getRequestURL().matches(regexp)){
/*send an error response*/
else{
 chain.doFilter(request, wrapper);
}
...
 }
 }

 filter
filter-nameBlockJspFilter/filter-name
filter-classBlockJspFilter/filter-class
 /filter
 filter-mapping
filter-nameBlockJspFilter/filter-name
url-pattern*.jsp/url-pattern
 /filter-mapping

 One could even go as far as to use the FilterConfig to pass in the
 regexps which could then be dynamically adjusted in the web.xml

Tomcat service on Windows 2000 stopped unexpectedly

[Yu, Albert]

Hi, All

I'm running multiple Tomcat4.1.18/JSDK1.4.2 instances on Windows 2000 (SP3)
as services. Unfortunately, those tomcat services randomly stopped
unexpectedly. Windows event log didn't tell much detail, Tomcat log either.

Does anyone have this kind of experience? How can I address it? Any

Re: mod_jk installation

[Albert Lunde]

I am trying to configure mod_jk 1.3 to work between Apache 1.3.27 with
mod_ssl and Tomcat 4.1.18 on Linux Version 7.1.
After installing Apache 1.3.27 and Tomcat 4.1.18 when I update
httpsd.conf with following two lines LoadModule jk_module
/libexec/mod_jk.so AddModule mod_jk.c
And then when I restart Apache 1.3.27 I get the following error:
=
Cannot load /usr/local/apache_1.3.27/libexec/mod_jk.so into
server: /usr/local/apache_1.3.27/libexec/mod_jk.so: undefined symbol:
ap_ctx_get
./httpsdctl start: httpsd could not be started.
===
I had a similar error that I fixed by changing the order modules were
loaded/added in httpd.conf: it was mod_jk using a routine from an
non-core Apache module. But I just tried searching the Tomcat/Apache
1.3.27/mod_jk sources for the string ap_ctx_get and I couldn't find
it, so I can't confirm that is the explanation here. The ap_ makes
me think it's an Apache routine. Could you be using mod_jk
built for the other Apache version (2.x)?
(I'm also still unable to get Apache 1.3.27+mod_jk+CoyoteConnector
all working together, but I'm stuck an a different error.)

JSP Issue with tomcat 4.1.18

[Albert Sidelnik]

I am in need of some help with an issue that I've encountered. I have an
application that's currently running on Weblogic 6.1 and I'm trying to
port the application to JBoss w/ Tomcat 4.1.18. The problem is that on
my JSP pages, the word null is being displayed on the page. Weblogic
treated these as blank strings (), but when I am trying to switch to
Jboss the word null is being printed. We had the same problem when
upgrading to Weblogic 7 from Weblogic 6.1, but they provided a fix that
when pre-compiling the JSP's, we could set a NoPrintNulls flag that
would basically use an empty string in place of the null string. Is
there a similar fix in Tomcat? I am sure that other people have had this
issue, but I have not been able to find anything in the other user
forums. I know this feature was changed as part of the JSP 1.2
specification, but I'm really hoping there might be a way to revert back
just like weblogic allows you. Thanks

Error while opening the workers: apache 1.3.27 Tomcat 4.1.18mod_jk

[Albert Lunde]

I am trying to use Apache 1.3.27, with Tomcat 4.1.18, and mod_jk on
Red Hat Linux 7.0

At the moment I'm getting what look like errors in the setup of 
mod_jk: two messages in the error_log saying Error while opening the 
workers, jk will not work. (see below)

(We are using Apache 1.3.x rather than Apache 2.x, because we need to
use some locally written authentication modules without translating
them to the 2.x API.)

This is Apache from the Red Hat RPM version 'apache-1.3.27-1.7.1', 
Tomcat from the binary distribution, and mod_jk built from 
jakarta-tomcat-connectors-4.1.18-src.

The Apache error log messages when I restart the servers:

I've posted a copy of my httpd.conf and files from the tomcat

http://pubweb.northwestern.edu/~lunde/tomcat-3-9-03/

I've tried using both org.apache.coyote.tomcat4.CoyoteConnector and 
org.apache.ajp.tomcat4.Ajp13Connector as the ajp13 connector with 
seemingly similar results.

I have both these files:

conf/jk/workers.properties
conf/jk2.properties

but I'm not too sure if they are correct or necessary. Are they read 
only by the connector class on the Tomcat side of the connection, or 
are they read by mod_jk as well?

I was able to find the line issuing the error in the mod_jk
source code, but I don't understand enough to say what is really
going on underneath, to know where I should be looking for a cause
or more specific symptoms.

The message is at line 1787 in jk/native/apache-1.3/mod_jk.c:

building just one connector module?

[Albert Lunde]

I'd like to to build mod_jk for use with an existing build of Apache
1.3.27 and the binary distribution of Tomcat 4.1.18.
But I've like to avoid building from source all the connectors for
all Apache versions. I'm not sure that I need anything beyond
the apache module for 1.3.x.
Is it feasible to build such a limited subset of stuff?

My initial experiments suggested two approaches: setting some
properties in a build.properties file to empty strings, and plugging
in jar files from the binary distribution where the build process
expects to find them.
Any advice on how to do this, other than trial and error?

(I'm presently working on Red Hat Linux 7.0 but will need
to do this again for Solaris 8 and/or a later version of Red Hat.)

 hmmm,  do you use RE at all in the init method of your class?

Nope, not at all.

 
 also now that I look more carefully at the stack trace, you might try
 looking at the compiled java for the calling jsp page. From your

 the calling jsp page is viewSample.jsp, do you use any RE's in 
 this jsp?

No, I just instantiated that class and called the method.


 
 the compiled java code will be found within the

 the offending line will be 367, because of the use of a $ in the

 you may have trouble vi'ing or more'ing the file.  I usaully ftp 
 such files
 to a windows machine.
 

Right, I looked at that java file, but the problem is the bulk of the entire 
generated class is one big Try block, and line 367 is just where the 
REException is thrown in the corresponding catch block.  So the actual 
problem could be anywhere...

The more I look at it, the more it seems to me like this is a potential Jasper

I have a Java class which uses the Jakarta regexp package for some

throwing it, it's Jasper.  When I do not instantiate this class of mine, 
the JSP displays perfectly.  Is there some documented incompatibility 
with using regexp within JSPs on Tomcat?  The only workaround I can 
think of is to use some other regular expression package that isn't used 
inherently within Tomcat.  Any suggestions?

Thanks for any help,

The stack trace you show would imply that your class is indeed throwing the
RESyntaxExeception.
I would guess you class definition or class method allows the passing of the
Exception to the invoking class, in this case Jasper.

I would remove any Throws RESyntaxException from the class/method def and
wrap a try/catch around the new RE() statement.


I'm pretty sure that's what I'm doing.  Here is the particular method 
that I'm calling, which is contained in a class called InternalLink:
   public String parseDescription(String phrase)
   {
   String linkTypeDescription = getLinkType().getDescription();
   String primaryEntityLabel = phrase +   + 
getPrimaryEntity().getId();
   String secondaryEntityLabel = phrase +   + 
getSecondaryEntity().getId();
   RE ent1Expression = null;
   RE ent2Expression = null;
   try {
   ent1Expression = new RE(_ENT1_);
   ent2Expression = new RE(_ENT2_);
   } catch (org.apache.regexp.RESyntaxException e) {
   throw new TrackerException(regexp problem);
   }
   linkTypeDescription = 
ent1Expression.subst(linkTypeDescription, primaryEntityLabel);
   linkTypeDescription = 
ent2Expression.subst(linkTypeDescription, secondaryEntityLabel);
   return linkTypeDescription;
   }

Here's the offending little snippet of JSP code:

   %
   }

   InternalLink[] sampleIntLinks = sample.getAllInternalLinks();
   int numIntLinks = sampleIntLinks.length;
   if(numIntLinks  0) {
   %
   h2Internal Links/h2
   table border=1
   tr
   thDescription/th
   thActions/th
   /tr
   %
   Arrays.sort(sampleIntLinks);
   for(int i = 0; i  numIntLinks; i++) {
   int linkId = sampleIntLinks[i].getId();
   %
   tr
   td%= 
sampleIntLinks[i].parseDescription(Sample) %/td
   tda href = 
deleteInternalLink.jsp?sampleId=%= idString %linkId=%= linkId 
%delete/a/td
   /tr
   %
   }
   %
   /table

Strangely enough, even if I don't call parseDescription() within the 
JSP, I still get the exception as long as I just instantiate 
InternalLink.  Any clue what's going on here?

Thanks for the help, and happy holidays to all,
-Al

Re: sites suddenly give internal server error

[Albert Csaba]

Yes, I started configuring it to support SSL, but I had no time to finish
it.
I removed the line where I specified the 8443 port, and it works fine again.

Thanks for your help and response,

 Hmmm,

 Can't really say what's definitely wrong.  Are you preloading any new JSPs
 or servlet'.  Something has changed, if you had a working system one day
 and the next it goes off like this.  Have you upgraded anything lately,
 JSDK, JRE?  Have the class paths been changed in anyway?

httpd + tomcat, using the root url

[albert]

Hi,
  I have to use cocoon (with tomcat) and squirrelmail in the same server.
  I wanted to use vitual hosts but cocoon must be used with SSL and named
  virtual hosts are not possible. Thus, I'd like to use
  https://www.myaddress.com for cocoon and https://www.myaddress.com/mail
  for squirrelmail, and possibly also http://www.myaddress.com/mail.

  I've tried something like this in the httpd.conf

Alias /usuaris /var/lib/tomcat/webapps/usuaris

Directory /var/lib/tomcat/webapps/usuaris
   Options Indexes FollowSymLinks
/Directory

Location /var/lib/tomcat/webapps/WEB-INF/
   AllowOverride None
   deny from all
/Location

LocationMatch /*
   SetHandler jk-servlet
/LocationMatch

Because I saw something similar with jserv but it seems jk-servlet doesn't
exist. Am I in the correct way? Does somebody have a smart solution for
the this?
  Thanks in advance!

tomcat virtualhost 404 error

RE:setting virtualhost .jsp path (was: tomcat virtualhost 404 error)

[Albert Csaba]

Yes, I can see a page telling me that the installation of tomcat was 
successfull. But where do I have to define the virtualhosts? I guess 
the problem is that when I'm trying to access 
http://www.vhost.xx/main.jsp, it doesn't actually gets the page 
from /home/sites/www.vhost.xx/web/main.jsp. 
I've read several documents for configuring tomcat for virtualhosts, 
but it's still not working.

Any help is appreciated,
thank you,

Re: confused - Installing tomcat4.0.4 on RaQ3 (Apache)

[Albert Csaba]

Thanks for your help. I'm not confused anymore. But still cannot download
the mod_jk from anywhere.
Google indeed gives so many links. But I tried that before. This list was my
last resource... The google links are or broken or getting me to the
download page for tomcat 3.x.

I have CVS on my server (1.11), but never used it. I could connect with it,
it says updating and stuff, but what then? How do I compile it?
Or how do I download what shows to me on the site?

 If you can use CVS, the best thing for jk2 (and possibly mod_webapp)
 is to grab the source that way. There are links to the CVS
 repositories on the jakarta tomcat homepage (
 http://jakarta.tomcat.org/ : take a look down the left hand side nav)
 including instructions on how to get the source.

 All of the apache/tomcat connectors are in the
 jakarta-tomcat-connectors module.

problems configuring Interclient on Tomcat

[albert woltman]

Hello,

I'm using Tomcat 4.0 and Interbase 6.5 together with interclient 2.5.
Now I would like to setup JDBC Realms so I made an entry in server.xml

Realm classname=org.apache.catalina.realm.JDBCRealm debug=99
 drivername=interbase.interclient.Driver
 
connectionurl=jdbc:interbase://localhost/d:/ou_webshop.gdb?user=dba;password=dba
 usertable=users usernamecol=user_name usercredcol=user_pass
 userroletable=user_roles rolenamecol=role_name/

And I put my Interclient jar in my classpath, but Tomcat keeps on saying it can't find 
any suitable driver, but Interclient is in my classpath.
What am I doing wrong, or knows anybody a workaround 'cause I'm going nuts here.

CLASSPATH = d:\InterBase\InterClient\interclient.jar

How was the precompiled mod_webapp.so binary built for Solaris 8

[Albert Chin]

How was the precompiled binary of mod_webapp available from
http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.0.3/bin/solaris8/sparc/
built?

I'm trying to build it with the Sun C compiler (Forte 6.2) as follows:
  ./configure CFLAGS=-mr -Qn -xstrconst -xO2 -xtarget=generic -xarch=v8 \
  CC=cc JAVA_HOME=/opt/java1.4 --with-apxs=[blah] --with-perl=[blah] \
  --disable-docs --disable-apidoc-java --disable-apidoc-c \
  --with-java=[tomcat dir] --with-ant=[path to ant]

I followed the instructions at:
  http://archive.covalent.net/jakarta/tomcat-user/2002/03/0209.xml
to fetch webapp and apr but get an error when trying to connect:

  $ telnet localhost 80
  Trying 127.0.0.1...
  Connected to localhost.
  Escape character is '^]'.
  GET /examples/ HTTP/1.0

  Connection closed by foreign host.

Using the precompiled binary above works fine!

Catalina - Memory Usage always accumulating after one week

[Albert Oscarina]

Hi Tomcat User,

I use catalina for my application. Everything seems good, but everyday, the
memory usage
accumulating, until every one week 99% memory has been usage. I must always
restart my Catalina
and everything back to normal again.

Do any body knows what happens ? Is it because my program ? or any body
encountered the same problem in Catalina ?

thanks

Re: Tomcat 4.0 and IterationTag

[Albert Pastrana]

Yes, I thought the same, because I did a similar tag some months ago, but I
looked at the JSP1.2 specification and docs and I saw that now, TagSupport
is implementing IterationTag (a new interface) and that the right way (the
other will be deprecated) to do an iteration tag is extending TagSupport.

thanks

 Hi,
 
 I've a tomcat 4.0 (downloaded latest week) in a Win2k pro.
 
 I've a little problem running it as service, but running stand-alone
 everything it's right.
 
 The first problem comes when creating an iteration tag. I've followed
 many explanations and, of course, read all the javadocs, and I cannot
 understand what I'm doing wrong.
 
 My code is something like that:
 
 public class RepeatTag
 extends  TagSupport
 {
int num = 0;
 
boolean endLoop()   { return num==10; }
voidnextElement() { num++;  }
 
public int doStartTag() throws JspException {
   if (!endLoop()) {
  nextElement();
  return EVAL_BODY_AGAIN;
  }
  return SKIP_BODY;
}

 } //end class RepeatTag
 
 And the problem is that my Tomcat is saying me that exception:
 javax.servlet.ServletException: Since tag handler class
 com.ludicus.general.taglib.RepeatTag does not implement BodyTag, it
 can't return BodyTag.EVAL_BODY_TAG
 
 I've read a lot of documentation about JSP1.2 and I think that's the
 right solution, but I supose I'm doing something wrong, could anyone
 tell me what's the problem?
 
 thanks a lot

Tomcat 4.0 and IterationTag

[Albert Pastrana]

Hi,

I've a tomcat 4.0 (downloaded latest week) in a Win2k pro.

I've a little problem running it as service, but running stand-alone
everything it's right.

The first problem comes when creating an iteration tag. I've followed many
explanations and, of course, read all the javadocs, and I cannot understand
what I'm doing wrong.

My code is something like that:

public class RepeatTag
extends  TagSupport
{
   int num = 0;

   boolean endLoop()   { return num==10; }
   voidnextElement() { num++;  }

   public int doStartTag() throws JspException {
  if (!endLoop()) {
 nextElement();
 return EVAL_BODY_AGAIN;
 }
 return SKIP_BODY;
   }

   public int doAfterBody() throws JspException {
  if (!endLoop()) {
 nextElement();
 return EVAL_BODY_AGAIN;
  } else {
 return SKIP_BODY;
  }
  }

} //end class RepeatTag

And the problem is that my Tomcat is saying me that exception:
javax.servlet.ServletException: Since tag handler class
com.ludicus.general.taglib.RepeatTag does not implement BodyTag, it can't
return BodyTag.EVAL_BODY_TAG

I've read a lot of documentation about JSP1.2 and I think that's the right

Re: Tomcat 4.0 and IterationTag

[Albert Pastrana]

Ok, thanks a lot, but that not solves my problem :(. I knew already the
IterateTag from Struts, but the question is that my tag will (should) be
something more than this Tag, and I need to make my own Iteration tag.
thanks

 Although this doesn't address the problem you're having with your tag, you
 should consider using the Struts tag library. The Iteration Tag in the
logic
 tags does exactly what you want and it's been tested extensively.

IIS with Tomcat: Change default servlet directory

[Albert]

Hi All,

I've installed Tomcat on Winnt4 with IIS4 and I've
followed the instructions in Tomcat IIS HowTo to let
IIS cooperate with Tomcat. It works if I set the home
directory of my Web site in IIS to d:\tomcat (for my
case, TOMCAT_HOME = d:\tomcat). I can run the servlet
examples included in Tomcat successfully. Now I decide
to change the home directory of my Web site in IIS to
another directory (for my case, new home directory =
d:\myWeb) and also put my servlet classes into another
directory e:\myServlet. However, I don't know how to
set config files to let my servlet classes be
executed. Would anyone help me with an example for my
case? Thanks in advance!!

Tomcat with IIS: errno = 61

[Albert]

Hi All,

I'm new in this mail list and I would ask for help. My problem is that I
installed Tomcat on Win2K Prof. with IIS5 for testing some servlet programs.
I followed the instructions in Tomcat IIS HowTo to let IIS cooperate with
Tomcat. After finishing all steps stated in Tomcat IIS HowTo and
restarting IIS, jakarta filter is marked with a green up-pointing arrow.
Then I added a virtual directory servlet which maps to
D:\Tomcat\webapps\examples\servlets under the default Web site where
D:\Tomcat is the TOMCAT_HOME. Afterwards, I restarted IIS again and tried to
open http://localhost/servlet/index.html in the browser, but no page was
displayed. I found that there was an error from isapi.log. The following is
a fragment of the log:

I heard that the problem is connection refusion due to unmatched ports
between Tomcat and IIS. However, I didn't modify any ports in
workers.properties, uriworkermap.properties and server.xml. I just used the
default settings. The port for ajp12 is 8007.

I really have no idea to solve the problem. If you want to examine my conf
files or have more information, please let me know. Thanks in advance!!

classpath questions

[Albert Yip]

Hi all,

I am wondering if someone can instruct me or point me in the direction on
how to make apps I create in the same tomcat to start with different
classpaths and libraries? Currently I add the jar file into the global
classpath but when I have more than one apps on tomcat, I run into trouble.
Tomcat is not able to call the servlets intended. For example, if I have 2
apps, App A with servlet a and App B with servlet b. When i use a browser
and call App A with servlet b, say http://127.0.0.1/appA/servlet/b,  it will
still work. How to avoid this?

Thanks,
Albert

jk_nt_service and NT error 2140

[Juergen . Albert]

Hi,

I'm trying to start tomcat as a Windows NT service and get an error when I
try to start the service.
The steps, I did:

- install tomcat 3.3m4 to x:\jakarta-tomcat-3.3m4  (drive x: is my
harddisk)
- install jk_nt_service.exe in the x:\jakarta-tomcat-3.3m4\bin directory
- edit the the file x:\jakarta-tomcat-3.3m4\conf\jk\wrapper.properties and
change TOMCAT_HOME and JAVA_HOME:
 wrapper.tomcat_home=x:\jakarta-tomcat-3.3-m4   (i also
triedtomcat-3.3-m3)
 wrapper.java_home=x:\jdk1.2.2 (i also tried jdk 1.3.0)
- install the service with:
 jk_nt_service.exe -I tomcat-3.3m4
x:\jakarta-tomcat-3.3-m4\conf\jk\wrapper.properties   (NT says ok)
- TRY TO start the service in the control panel/services dialog:

--- NT says: Error 2140

Did I forgot something or did I misunderstood something or is there a real
problem with jk_nt_service.exe?

Thanks in advance,

RE: tomcat exception

[albert]

hi,
I try to help, may be this can solve your problem
1) Delete all the *.java file inside the jar file 
2) put the class in \webapps\ROOT\WEB-INF\lib
3) check your classpath setting, it must be point to your jar file, (e.g :
\webapps\ROOT\WEB-INF\lib\myjar.jar)

re: if mod_jk can be compiled statically in Apache

[Khokhlov, Albert]

Hello all,
I'm a bit new to Tomcat so please pardon me if this issue has been addressed
before but I have followed as much as I could from the documentation and
could not find solution for my needs. 
Basically, our company has been used JServ for number of months and now we
are trying to implement Tomcat (simple replacement Jserv on Tomcat). 
With Jserv we had build Apache statically. The idea behind TOMCAT is same,
- keep Apache statically.
- build TOMCAT as out-of-process servlet engine. 
Prior to send email to users mailing list, I checked TOMCAT documentation +
mailing archive but could not find an answer  if I can compile mod_jk
statically in Apache --with-apache flag. 
I been able to find some discussion about it under developers mailing list
but still not be able to find exact syntax for ./configure to build mod_jk
statically on SUN Solaris platform ( all documentation refer to Apache with
DSO and apxs command).
If anyone from users group will be able to answer my question, it would be
real appreciated. 
Awaiting kind reply.

 where do I place the various files?

 Hi,
 
  CA Have you looked at [..]
 
 Yes, I've read those, but that doesn't work. Tomcat still gives me
 an Class "dbapi.dbHandler not found" error. I've created a JBuilder
 project in h:\local\browser\WEB-INF and after compilation the
 'classes' and 'src' directories are present in this directory. I've
 created a context in Tomcat which docbase is h:\local\browser, but
 still it can't use the classes.
 
 What more needs to be done? Anyone?
 
 Mvg,

Bob,
Have you tried to package your application in
a WAR archive along the lines of the doc I suggested earlier, and
deployed that in TOMCAT_HOME/webapps ?
I don't know much about Jbuilder but if you have the right war
structure, web.xml and tomcat server.xml configurations it should work.

For example, lets suppose your application is called
"browser", then "browser" should be a directory containing, say, at
least the following, assuming one class:

browser/WEB-INF/web.xml
browser/WEB-INF/classes/dbapi/dbHandler.java
browser/your-jsp.jsp

Where your-jsp.jsp has something like

jsp: ... class="dbapi.dbHandler" .../

isapi_redirect.dll won't load with IIS 5.0, Win 2K and Tomcat 3.2.1

[Albert Schreuder]

Dear readers,

We have problems loading the isapi_redirect.dll to 
run Tomcat in combination with IIS.
We have followed all the instructions in the How-to 
document.

But it seems like the isapi_redirect.dll is not 
loading. In the document is stated that een green up-pointing arrow should 
appear. All that we get is een red down-pointing arrow.

Who can help us?

Coupling IIS - Tomcat

[Albert Schreuder]

Dear reader,

I tried to couple IIS with Tomcat. For so far I 
know, I followed all the instructions described in the document "Tomcat IIS How 
To".

Only I have one problem, in the document is pointed 
out that when the ISAPI filter is installed, I should get an uppointing green 
arrow. All I get is a downpointing red arrow. 

I double checked all the entries in register. But I 
could find nothing wrong.

I use IIS 5.0, Win 2K, Tomcat 3.2.1 and het 
ISAPI_redirect.dll that was found under binairies from tomcat 3.2.1. 
beta.

Do you have any clou's about what can be 
wrong?

With kind regards,

Re: Tomcat/Apache port number use

[Christopher Albert]

Hans,

Lets try one more time, assuming there are some configuration
problems. For example, I can replicate the analagous error on
my linux box by commenting out the JkMount lines in my mod_jk.conf file.
So I'll start with a series of diagnostic questions, trying to figure
out what is going wrong.

1. After you restart Tomcat, do you restart Apache?
Whenever the httpd.conf file changes, apache needs to restart,
and thanks to the Include of mod_jk.conf, this latter file is
part of httpd.conf.

2.The apache httpd.conf file is very sensitive to the order
of its arguments and instructions. Make sure the LoadModule and
AddModule lines for mod_jk are in the right place.

3. Try making a copy of your mod_jk.conf and workers.properties
files and put them in you apache-root/conf directory, and configure
these files appropriately, along with httpd.conf for the new paths.
Then restart tomcat, and then restart apache and see what happens.

Re: Tomcat/Apache port number use

Well Hans,
I tried to ask all the simple, obvious questions.
TOmcat is working fine(8080), Apache is working fine
and seems properly configured. I can't give you any
other advice but to go back, get the src for mod_jk
and recompile and install it (using apxs if you can)
with the right solaris parameters. There have been some
postings on this list for those.
Good luck,

Re: Tomcat/Apache port number sue

Hans,

Normally port 8080 is for tomcat's own web server.
So when I connect to http://www.kindserver.com:8080,
I get tomcat's default home page from the tomcat 
web server. Mod_jk works with apache on port 80.

First what do your mod_jk.log and tomcat.log and apache error.log
files say?
Next we need to see the relevant parts of you mod_jk.conf and
workers.properties files.
WHat kind of system are you running on?

Re: Linux and Tomcat

[Christopher Albert]

David Oxley wrote:

 I am about to install our software onto a RedHat 7.0 box. I have tried
 before to install Sun's JRE onto RedHat and failed. I have a couple of
 questions:

 1. What is the best JVM to use? (Stability more important than performance)

I recommend the IBM version; you can download an rpm for linux from their
site.
Then I would go get H.Gomez's tomcat rpms ; for example from
ftp://rpmfind.net/linux/falsehope/home/gomez/tomcat

which will install tomcat for you as well as an init script to start tomcat as

a service at boot. He also has rpm for the necessary apache modules(mod_jk),
and various versions of tomcat, in case you need to change. I strongly
recommend
these: all the hard work has been done for you.


 2. Are there detailed instructions on doing the install anywhere?

If you get GOmez's rpms, get the manual rpms as well.
ANd even if you decide to use SUn's jvm, get the rpm too.


 3. What is the difference between green and native threads?
 4. For Suns JRE 1.3, what does the classpath and path have to point at?

In general, if you want to type "java" at the command prompt to execute it,
it will have to be in your shell's path. Suppose you installed the IBM rpm,
then you will need to set JAVA_HOME=/opt/IBMJava2-13, for Sun' s rpm
You will do JAVA_HOME=/usr/java/jdk1.3 (or /usr/java/jdk1.3.1, if you get the
latest beta version). Then you can add lines like the following to your
.bashrc
export  JAVA_HOME=/opt/IBMJava2-13
export PATH=$PATH:$JAVA_HOME/bin

For CLASSPATH, this really depends on what you wnt to do. If you are
just using tomcat, the script that gets put in /usr/bin/tomcat will do it all
for you.


 5. As I'm new to Linux, where do I set the classpath and path so they are
 set for every boot?

for $PATH, you should read up on some basic linux books. This is set to
a basic path from init, and then when shells are invoked it usually gets
modified. Look at .bashrc and .bash_profile in your home directory.

If you want to set a $CLASSPATH , you can make a script say
"classpath.sh" and put it in /etc/profile.d/ . Check out some of the scripts
there
for ideas. However, be warned that the CLASSPATH variable is quite sensitive
across a large range of Javaz applications, and it is often better to tailor
it
to each application.


 6. Difference between -server and -client and do they both run hotspot as
 default?


These are Sun specific, and dont work with the IBM java binary.


 Thanks.
 Dave.

Hello All,
I have a question regarding application path in Tomcat. I have
loaded and application named "myapp" under 'webapps' of Tomcat. Now, is it
possible to know the full path of my application "myapp"?[i.e upto and
including
the folder 'myapp']

Thanks in advance,

Saikat
