Re: Problems wth Apache, mod_jk2 and Tomcat

[Christoph Fischer]

Hi,
this seems also to be a problem in mod_jk , tomcat4.1.10, apache 1.3 on 
a linux server however it does build up slowly over the day.
The problem seems to be that the connection via mod_jk (Port 8009) does 
not close, so the java/tomcat processes
will not quit after responding to the request (or the other way 
around?). This problem occurs only in
heavy load situations. After that I see many open socket connections an 
some tomcat processes that will not quit.

Snapshot of the logfiles:
tomcat / catalina.out:
Failed to authentice as null
Error number: 50
tomcat / catalna_log:

[Fri Oct 22 08:52:34 2004]  [jk_ajp_common.c (1137)]: Error reading 
reply from tomcat. Tomcat is down or network problems.

Is this a mod_jk problem not closing the connections or a tomcat problem 
not telling mod_jk that it's finished or a system problem not
releasing the sockets ?

Thanks for any ideas...

Hi,

We use Apache 2.0.52 with the Tomcat 5.0.25 and its included

Usually Apache uses 230 slots out of 1000 it has set as the 
maximum. This can be seen from the server-status page, it equals to 
say 32 requests per second.

Then all of sudden the Apache runs full and exceeds all empty 
slots, ie. goes up to 1000 requests currently being processed and 
accepts no further connections. All but a handful of these slots 
are in state "W". Looking at the URI's the requests are both static 
content (like images) served directly by Apache, but of course many 
requests are to the dynamic content created by the app server 
(Tomcat).

I do not think this is a load issue per se, ie. where we have 
someone hammering us with requests, since looking at the 
connections and URL's they are all so random but valid at the same 
time that I do not think this is it.

What puzzles me more is that they are all in the state "W". which 
means "sending reply". The network seems to be OK at that point of 
time too since I can connect to the machines no problem.

Only if I restart Apache by ultimately killing (killall -9 httpd) 
all processes I can revive the site. After the Apache restart 
everything goes back to normal right away. This seems to mean 
something too, at least that it seems to be getting stuck somehow 
but whatever caused it does not seem to exist anymore. Like 
something short, for example a specific request, caused this.

What could I check from here? I cannot take the Apache out since we 
need  it for rewriting and session handling.

Any help or pointers are greatly appreciated.

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.

Manager Error

[Carl F. Hall]

I've copied manager.xml from localhost to another host, say testhost1.com.
When I access testhost1.com/manager, I'm prompted and login successfully.
I'm shown 2 contexts; / and /manager.  Whenever I try to reload "/", I get
"FAIL - No context exists for path /".  I've tried doing the same for other
hosts and get the same error.  Is there something I've misconfigured or
missed alltogether?  Where should I start digging to get this working?

OK. But is that a correct RFC address?  I understood from the JavaMail

RFC-822 addresses?

So is this allowed

or should it be

or just

RE: Why mail/session always being set to localhost even Context.x ml says otherwise?

[Phillip Qin]

I use 5.0.28 and Tomcat Manager/catalina-ant tasks. The context file is
called context.xml and is lcoated at META-INF in war. When Manager deploys
web app, it

- uploads war to ${catalina_home}/webapps
- expands war to ${catalina_home}/webapps/yourapp
- copies context.xml to ${catalina_home}/${engine}/${host}/yourapp.xml

Use war task should help you properly package your web app for deployment.

I have read the spec 'srv.7 Sessions', and it is very clear, but not

What I am looking for is the tomcat documentation on its session

Where can I find mod_jk2 for apache 1.3?

[Sergey Kamshilin]

Hi all,

Trying to find the subj. The link on jakarta web site has a tar file with
mod_jk2 for apache 2. The readme file states that there should be a version
for apache 1.3 but it's not there. Does anybody have idea where can I
download it from?

Thank you!

/Sergeyk

Ah, good to know! I was unaware that Tomcat substitute properties in 
context.xml. I dumped the properties in my servlet (an axis-based web 
service, actually) and there doesn't seem to be a suitable property 
available. But as I'm using Spring and Log4j anyway, I noticed that

org.springframework.web.util.Log4jWebConfigurer in conjunction with
org.springframework.web.util.Log4jConfigListener

sets an appropriate property. It needs some declarations in web.xml:

  
webAppRootKey
mywebservice.root
  

  
log4jConfigLocation
/WEB-INF/log4j.properties
  

Then, in context.xml

  

  

It's not pretty, rather fragile, really, as it depends on the right 
order of evaluation. The url attribute must be evaluated after 
mywebservice.root is already set.

Thanks for reminding me. In this case it's okay to lose the data as it's 
read-only reference data.

Re: Problems wth Apache, mod_jk2 and Tomcat

[David Smith]

I would start with the apache logs and find out what kind of requests 
are logged in the access just before the event.  That should get you 
going in the right direction.

Hi,
We have an odd problem we cannot solve. Maybe someone else has come 
across this too.

We use Apache 2.0.52 with the Tomcat 5.0.25 and its included mod_jk2 
with Coyote/JK2 AJP 1.3 connector.

Usually Apache uses 230 slots out of 1000 it has set as the maximum. 
This can be seen from the server-status page, it equals to say 32 
requests per second.

Then all of sudden the Apache runs full and exceeds all empty slots, 
ie. goes up to 1000 requests currently being processed and accepts no 
further connections. All but a handful of these slots are in state 
"W". Looking at the URI's the requests are both static content (like 
images) served directly by Apache, but of course many requests are to 
the dynamic content created by the app server (Tomcat).

I do not think this is a load issue per se, ie. where we have someone 
hammering us with requests, since looking at the connections and URL's 
they are all so random but valid at the same time that I do not think 
this is it.

What puzzles me more is that they are all in the state "W". which 
means "sending reply". The network seems to be OK at that point of 
time too since I can connect to the machines no problem.

Only if I restart Apache by ultimately killing (killall -9 httpd) all 
processes I can revive the site. After the Apache restart everything 
goes back to normal right away. This seems to mean something too, at 
least that it seems to be getting stuck somehow but whatever caused it 
does not seem to exist anymore. Like something short, for example a 
specific request, caused this.

What could I check from here? I cannot take the Apache out since we 
need  it for rewriting and session handling.

Any help or pointers are greatly appreciated.

First try another browser.
Then, maybe your tomcat is configured to use cookies as session ids and your

cannot believe this were a bug in tomcat.

Steffen,
the problem appears using both IE and Firefox.
My firefox browsers (on the tomcat host (xp pro) and a linux host  are 
both set to 'use cookies - normally'.

I did a search of my tomcat installation for the word cookie, but that 
did not find any obvious
configuration of cookies, so I assume I'm running the default.

I tried allowing my browser to accept cookies from explicitly 
localhost:8090 (my tomcat server) , but it made no difference.

I have not yet found where in the tomcat documentation, session 
definition, cookies, etc. are discussed

Re: JK2: mapping urls from Apache to Tomcat

[Lars George]

Andrzej,
If you are referring to rewriting URI's before hitting the app servers 
then we do this with mod_rewrite which executes before mod_jk. So fr 
example if we have to change a legacy URI to a new one then we do this 
with a rewrite rule before even mod_jk is called. Works great for us.

HTH,

I'm trying to do the same thing. I want Apache/JK2 to trap a specific URI

"manager") before it sends the request on to Tomcat through the JK 
connection.

The context parameter shown above in workers2.properties does not do this, in 
fact, who knows what it does. I agree with Doug that the JK2 docs are 
abysmal. 

Anyone figured out a way to do such URI mapping using JK2?  Is it even 
possible?

Re: Running HSQLDB in-process?

[Peter Rossbach]

Hey Michael,
I think you can used ${catalina.base} or other system env variables 
inside server.xml and context.xml
for an absolute path information. Only problem with this handling is, 
don't save your server.xml oder context.xml
with the admin application.

Tipp: use a db resource path outside your application, than deployer can 
delete all
files without you lose the data! ;-)

hope it works,
Peter
Michael Schuerig schrieb:
I'm trying to run HSQLDB in in-process mode in a web application. For 
this I've added a resource definition to the context file:

 
No problem so far. But there is a problem, when HSQLDB tries to open the 
database and can't find it:

   java.sql.SQLException: Database does not exists:
   file:/WEB-INF/db/verzeichnisdb
Now, what I need is some hook where I can resolve this to an absolute 
path. Unfortunately, what looks like an ordinary file-URL isn't one. 
That is, AFAICT, it wouldn't help to resolve this to a jndi-URL (I 
think that's what Tomcat does). If my understanding is correct, I need 
an absolute file-URL as HSQLDB interprets the URL scheme to decide how 
to access the database (server, file in-process, in-memory).

As a last resort, I could run HSQLDB as a server and be done with it. 
But as only my single web app is using the DB there's no independent 
reason to do this.

Can you give classes12.jar a try so we can isolate the problem of ojdbc14. I
use the jdbc driver come with oracle 9i release 2. The name is

RE: Where do UnavailableExceptions get reported?

[Steve Kirk]

> Throwing a generic ServletException wrapping my UnavailableException
> would probably get the report showing up, but it also means Tomcat won't
be
> able to respond correctly to it.

Yes.  Sorry, I had missed the fact that UnavailableException is a subclass
of ServletException, so unless your web.xml specifies an error-page for
UnavailableException, there _shouldn't_ be any need to wrap an UE inside a
SE anyway.

But, back to your original question:
> > Where does it go?  If it disappears, what good is
> > having
> > UnavailableExceptions being thrown?

I've had problem with error and exception handling myself, so you got me
interested in this one.  I just read up on it in the servlet spec.
Interesting.  It seems that one good reason to use UEs is that servlet
containers are supposed to give them special treatment compared to SEs (see
servlet spec SRV.2.3.3.2).  It may be that this special treatment is
actually the problem that you're experiencing?

What I mean by this is, that the servlet spec requires TC to return a 404 or
503 to every request to the servlet after it has thrown the
UnavailableException (up toa time limit in the case of a temp UE).  So, each
new request to that servlet produces a new 404 or 503 error.  Therefore you
probably wouldn't expect each of these new Exceptions to contain the error
message from your original UnavailableException (and the spec does not seem
to require this as far as I can see).  This is maybe why a generic exception
message is returned each time instead.  At a guess, you are seeing the
UnavailableException manifested as a 404 error in your browser, like this:
"HTTP Status 404 - Servlet hemlock is not available", rather than an
UnavailableException ?

PS I just ran my own test of UnavailableException along the same lines that
you described, and found that my custom UE message was not shown in the
browser, but WAS logged in my catalina log file:

2004-10-25 17:30:31 StandardWrapperValve[uethrower]: Servlet.service() for
servlet uethrower threw exception
javax.servlet.UnavailableException: MY UE MSG
at myWebApp.test.UEThrower.doGet(UEThrower.java:24)
...
2004-10-25 17:30:31 StandardContext[/ao]Marking servlet uethrower as

Re: GZip compression in 4.1.27 ..

[Jacob Kjome]

I'm not 100% sure of this, but I don't think GZIP compression was added to the
connector until Tomcat 5.0.xx.  Look at the appropriate docs to verify this. 
Either way, you can always write a servlet filter to do the compression.  This
way you don't have to worry about whether Tomcat (or any other app server)
natively supports gzip compression.

Embedded Tomcat5 - access to Context file

[sven morales]

1.  How do I access the context file, the ones
separated from server.xml and put in the
tomcat5/conf//localhost/ ?

2. Or if embedded in the war file, how to access it
from the war file's  META-INF/contexfile.xml  ?  I
need access to  where the datasource and
jndi is normally defined.

3.  Similarly how to access the
myapplications/WEB-INF/web.xml ?  In this web.xml it
references jdbc/Taglib but it is stored usually at
server.xml or the new fragment contextfile.xml.

I am looking at StandardContext,  Context and
NamingResources api and am just not clear how to go
about  setting it up to look for example jdbc/Taglib
defined in the contextfile.xml.  My understanding is
the Digester reads these xml file, but how do I get
hold of the results it parses?   Furthermore, is there
a different Digester instance that reads the
server.xml, web.xml, and the contextfile.xml? 
Any help in how to put these together mixing both
config  xml files and programmatically?

Thanks in advance.

Re: GZip compression in 4.1.27 ..

[Dave Been]

I posted last week I tried compression="on" compression="force" and 
compression="5" for compress output if > 5 bytes without any success.
Note that your client must send the header "Accept-encoding: gzip" for a 
web server to consider you as able to consume it.  i use

 "Accept-encoding: gzip, compression", e.g.
httpConn.setRequestProperty("Accept-Encoding", "compress, gzip")

I'm using a pure java client using the standard java.net API and it is not 
working for me.
We communicate with POST, not GET, and our typical response packet size is 
> 2k up to 5Meg.

Another person in our group got Httpd 2.0 configed to do this, but with 
another web server.  I use tomcat, so .
Next step is probably to build tomcat and try to figure out what its 
problem is (in eclipse).

Is your client Java?   i suppose i could write a small test app/servlet. 
would that be useful?

Dear Ladies and Gentlemen,

This is a follow-on for a question from last week, but as its now on a
"different-page" of the mailing list. I decided to
post another new questions, so no-one misses it.

1) Below is an original extract of my tomcat 4.1.27 server.xml.  I want to
enable compression in my HTTP connector.
I have a customer with v. low bandwidth. I have read the Apache readme
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/coyote.html on 
this,
but I am still not 100% clear.


Would I be right in understanding that *ALL* I need to do (in the case of 
TC
4.*) is add the following attribute compression="on" ???







2)  Any suggestions on a way of testing this in our high bandwidth
environment first ?

Step back ;)  This memory is used.  It's not wasted.  It has a purpose.
It's not a memory leak.  If it were wasted or a leak, I'd agree with
you.

But it's plausible that given your technology choice of AWT's ImageIcon,
your memory quota is inadequate and needs to be revised.  54MB is
virtually nothing for server apps.  (If you're running Tomcat on J2ME or
a portable, I completely understand your concern, but then again in that
case you wouldn't be using this approach anyways).

Don't look at overall heap size as a measure of an app's quality.
Requiring more memory in order to ensure better performance is a typical
and usually good tradeoff.

So what?  Right now, my Tomcat server is sitting taking up 24mb.  When the

RE: Where do UnavailableExceptions get reported?

That's a possible workaround.  But the JavaDocs are pretty clear: 

 public class UnavailableException extends ServletException
 
 Defines an exception that a servlet or filter throws 
 to indicate that it is permanently or temporarily unavailable. 

 When a servlet or filter is permanently unavailable, 
 something is wrong with the it, and it cannot handle requests 
 until some action is taken. For example, a servlet might be 
 configured incorrectly, or a filter's state may be corrupted. 
 The component should log both the error and the corrective 
 action that is needed.

Throwing a generic ServletException wrapping my UnavailableException
would probably get the report showing up, but it also means Tomcat won't be
able to respond correctly to it.

I'm not sure it is.  That's a problem with wrapping Exceptions, mine's a
problem with reporting them.  Slightly different.

RE: Where do UnavailableExceptions get reported?

[Steve Kirk]

If you really need to, you can wrap one exception inside the other, e.g.

throw new ServletException(new UnavailableException("my unavaiable
message"));

and I think you'll find that the Tomcat error page (or your own custom error
page, if configured) will automatically strip the outer ServletException
layer off and report the underlying UnavailableException.

I think your problelm might be related to my previous post regarding a
similar issue with ServletException:
http://nagoya.apache.org/eyebrowse/[EMAIL PROTECTED]
he.org&msgNo=158528

I have also submitted a report to the JSR154 team as suggested by Yoav.  Let

RE: cookies problem with Tomcat 4.1.30

[Steve Kirk]

I haven't experience this myself, but as no-one else has responded yet, here
are some thoughts that come to mind in case they help :-)
 
Perhaps the session associated with cookie C1 has expired by the time that
Tomcat receives the request that contains C1?  Then, if your code uses
request.getSession(true), this might be creating a new session, and a new
cookie is returned for the new session (C2)?  Or is C2 a cookie that was
already in use by another user?
 
Is it possible that there is a cacheing server somewhere between browser and

Are you using any javascript code in the browser to read/write cookies, or

Subject: cookies problem with Tomcat 4.1.30


Hello there,
 
We experienced strange behavior with Tomcat under heavy load. 
 
Fairly simple JSP generates a page based on a persistent cookie,
unfortunately the browser receives someone else page. 
For example, browser B1 sends request with cookie C1, but receives page
based on cookie C2. 
 
Anyone with similar experience? Is it possible that Tomcat did not
initialize reused objects like Request or tag? What else is shared between
requests?
 
Unfortunately it's not reproducible even when we create artificial load, so
we could only guess for possible reasons.
 
Thanks in advance,
Todor

RE: Can Tomcat be configured to be an FTP Server?

From: Dov Rosenberg

If you need to include some logic with your FTP, you should 
really look at Kermit (I think it is from University of 
Chicago). It has the best command line interface around and 
is very capable and open source to boot. You could easily 
wrap a servlet around it if needed

Now there's a thought!
Has Kermit progressed from the 232+tty interface it had last time
I used  it :-)

Thanks.

Hi,
If you want the Manager webapp to use the context-specific XML file you
have to tell it, using the path and config params on the same deployment
URL.  This is covered in the Manager doc page,
http://jakarta.apache.org/tomcat/tomcat-5.0-doc/manager-howto.html,

You might want to read up the Servlet Spec's section on resource-ref and
env-entry refs.  These provide a way for you to keep one WAR and edit
server.xml (or another server-specific, outside-your-WAR configuration
file) to modify configuration information.  Your understanding above is
incomplete.

RE: discussion on webapp reload in production environments

[Shapira, Yoav]

Hi,
Yeah.  Webapp reload is a great thought and sometimes possible to do
in-place in true-hotswap fashion.  Unfortunately in the real world there
are several factors which prevent this from really happening.  They
include:

Libraries that use static resources in such a way they can't be
reloaded.  Libraries that use System resources (as in System
classloader) in such a way they can't be reloaded.  Libraries that spawn
off their own threads and don't manage them properly.  These things can
be hard to track, and can be in your code, the library code, or the way
your code uses the library.  This is exemplified in Bugzilla 26372.

Another reason is that real apps frequently do a lot of things on
startup (and sometimes shutdown).  So the reload even if it worked
perfectly would take an unacceptable amount of time.  So sites that
really can't afford downtime don't do in-place reloading.  They have
either a server cluster where they update server at a time, taking it
off the cluster for the update instead of doing an in-memory reload, or
they much with context paths, e.g. /appv1, /appv2, and /app with /app
being just forwarding filter.  Both of these approaches have been
explained and successfully used on this list in the past.  There are
other approaches as well when you throw other pieces into the mix, such
as Apache, Squid, etc.

So I'm sure there are people out there doing webapp reload in-memory in
true hotswap fashion, and that's great for them.  But I think they're
the minority and that the state of the industry right now means it's
extremely difficult to do it perfectly.  Most of things the container
can't solve for you.  And that's why we take the approach of addressing
the issues that are shown conclusively to be Tomcat bugs, and not
jumping through hoops to cover faults created by other libraries,
because that ultimately reduces the maintainability, speed, and quality
of Tomcat itself.

By the way, these arguments are not Tomcat-specific (except for the last
sentence above obviously ;)).  I've had the same experience with the $$$
servers I use.  In-memory webapp reload is a good goal, great marketing,
and sometimes works well in real life, but not that often.  YMMV.

RE: [Slightly OT] coercing AWT/image libraries to release resources

A profiler would show you what references are being kept, so that might

I believe (and I'm sure I'll be corrected if I'm wrong), the drivers

Re: Can Tomcat be configured to be an FTP Server?

[Dov Rosenberg]

If you need to include some logic with your FTP, you should really look at
Kermit (I think it is from University of Chicago). It has the best command
line interface around and is very capable and open source to boot. You could
easily wrap a servlet around it if needed

Re: Does Oracle 9i thin jdbc driver work in Tomcat 5?

[Dov Rosenberg]

I have successfully used Oracle 9 with JBoss, Jrun, and Tomcat. I don't
remember any specific differences between the JNDI configurations. Make sure
that you have the classes12.jar, nls_charset12.jar files in your runtime
classpath, i.e. /WEB-INF/lib or somewhere else.

The driver class is oracle.jdbc.OracleDriver
The URL format is: jdbc:oracle:thin:@::

In your code you need to create an instance of the Oracle connection pool
class.

I think Oracle10g renamed the jar files to something like ojdbc14.jar.

Simplify your life: rely on formal releases instead of updating
piecemeal (e.g. tweaking a JSP on a live site).

In theory, you should be able to automate the following:
1/ pull a release label from source code control
2/ build the code, package it up into a WAR file (this includes JSP
precompiles)
3/ push the new WAR out to your Tomcat server(s)
4/ stop Tomcat, clear the work dir, restart Tomcat

For rollback purposes, you'll want a step 3.5: stash the original WAR
file somewhere.

I try to precompile my jsp's, copy all the precompiled JSP's into a JAR file,

Steven J. Owens wrote:
Hi folks,
 I'm interested in hearing how people are dealing with
configuration management issues.
 We've been running into some problems with JSP recompiles,
particularly when the changed JSP is an included JSP.  Tomcat seems to
sort of get stuck on the old version, even if we restart tomcat it
doesn't reload.  Manually deleting the foo_jsp.java and foo_jsp.class
files from the tomcat/working/etc directory and *then* restarting
seems to do the trick.
 Somebody I talked to suggested that using a WAR file and
redeploying would make tomcat more reliably recompile the JSPs.
I've been meaning to move to using WAR files sooner or later, but
one question has always bugged me - how do you save your
deployment-specific configuration info?  

 If I understand correctly, WAR file is just a glorified JAR file,
which in turn is just a glorified tar file.  So unless you're
unjarring it, editing the config file and rejarring it, you can't
really muck with the config settings inside it.  How/where do people
normally keep the configuration variables for the webapp?
 We have a single tomcat installation with a dozen
almost-identical webapps, one webapp for each customer.  When we do
our jobs right, each app is in fact identical, except for:
- two colors in the app-wide CSS stylesheet
- the customer's logo image
- the  tags in server.xml
- a few details of the web.xml file (webapp name, database resource name)
- a properties file with a couple dozen configuration properties
- a separate database in the mysql server
 We extend and refine the application constantly, so we're
changing the code every month or two.  So far we've been using cvs to
manage this.  Each webapp is a cvs checkout ; the specific files
mentioned above exist in template form in the checkout
(e.g. web_template.xml, styles_template.css) that we copy into the
right name for deployment and then edit, so they don't get overwritten
by cvs.
 Using cvs worked pretty well for a while, but it's gotten
unwieldly, especially when we run into the JSP recompiling problem,
because then we have to restart the entire server to try to get it to
recompile the jsp.
 This reminds me of another question; I'm beginning to wonder if
we wouldn't be wiser to use a dozen separate tomcat installations.  I
know that in theory using the same tomcat installation for multiple
webapps is supposed to be "standard", but any time we have to tweak
the server.xml-level configuration of a single webapp, we have to
restart all of them.  How do people normally deal with this?  Is it
at all common to run multiple tomcat servers behind apache for this
sort of purpose?

Re: AW: AW: Session Definition Bug?

There is a plugin to Mozilla/Firefox that allows you to watch your

http://livehttpheaders.mozdev.org/

With that installed, you will be able to see if the browser is sending
back session IDs properly.

BTW: I use Mozilla and Firefox and have never had this problem.

catalina.policy and default settings for web applications

[Thomas Zumbrunn]

I'm running Tomcat 4.1.31 with SecurityManager and tried to understand the 
default settings for web applications in conf/catalina.policy.

Lines 83-91:
[...]
// These permissions are granted by default to all web applications
// In addition, a web application will be given a read FilePermission
// and JndiPermission for all files and directories in its document root.
grant { 
  // Required for JNDI lookup of named JDBC DataSource's and
  // javamail named MimePart DataSource used to send mail
  permission java.util.PropertyPermission "java.home", "read";
  permission java.util.PropertyPermission "java.naming.*", "read";
  permission java.util.PropertyPermission "javax.sql.*", "read";
[...]

As far as I understood the comments, I thought this would allow me to specify 
JDBC DataSources and mail sessions as Resources in my context and then make 
use of them in my servlets with

Context initContext = new InitialContext();
Context envContext  = (Context) initContext.lookup("java:comp/env");
DataSource dataSource = (DataSource) envContext.lookup("jdbc/foo");

and

Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
Session session = (Session) envCtx.lookup("mail/Session");

respectively. However, I had to add additional permissions to catalina.policy 
to make the servlets work:

grant codeBase "file:/path/to/my/webapp/WEB-INF/classes/-" {
  permission java.net.SocketPermission "mysqlserver:3306","connect,resolve";
  permission java.util.PropertyPermission "javax.mail.Session.Factory","read";
  permission java.net.SocketPermission "mysmtpserver:25","connect,resolve";
};

Is there a more elegant way to achieve the same result (e.g. without changing 
catalina.policy)? Any advice is very much appreciated.

Cheers

AW: AW: Session Definition Bug?

Hi

> I'm using the firefox browser and have no proxy definitions.

First try another browser.
Then, maybe your tomcat is configured to use cookies as session ids and your
browser is configured not to accept cookies?

However, since there is no different code for local and remote clients, I
cannot believe this were a bug in tomcat.

RE: error while starting Tomcat5 service

[Allistair Crossley]

I thought you had to have Tomcat 5.5 with JDK 5.0. If you are using Tomcat 5.0 there 
is a compatibility download that should be installed. 

If that is not your problem, try uninstalling the service and use the 
tomcat/bin/service.bat install method.

Allistair.

Hi,
HTML emails don't work on ASF lists (in general), so we can't see your
image.  If there's a full error with stack trace in any of your logs, post
that.

I worked with EMC for a few months about seven years ago.  ;)  Though not in
India, but in their HQ here outside Boston.  Good company, was some wicked
cool hardware reliability stuff at the time.

discussion on webapp reload in production environments

[Allistair Crossley]

Hi,

Yoav, you suggested we should pick up this thread here in the list rather than the 
bugzilla report at http://issues.apache.org/bugzilla/show_bug.cgi?id=26372

I have copied the last 4 replies for any interested parties to start following this 
thread.

I look forward to hearing the position on webapp reloading in terms of desirable 
behaviour and the specification when you have time to do so.

All the best, Allistair.

YOAV
I'd point out it's only 'dying' when you're trying the 
app reload, nor normal usage.  This feature is not mandated by the Spec so we're not 
obliged to provided it in the first place: it's caused mostly trouble 
and has very limited usage in production environments.  So if you have patches 
for it, that's great, but the common usage scenario for Tomcat doesn't include 
webapp reload, and so doesn't suffer from this issue at all.

ME
I am interested in your comment that reload of webapp is mostly trouble and limited in 
production environments though. My understanding was that if you 
want to make a build to production or a patch of some files, you would use ant 
or similar as we do here to reconstruct the WAR to deploy. Does this not 
require tomcat being able to reload? In fact, we tell the business the intranet 
will be down for 5 minutes and post a message page up for inbound requests. We 
stop tomcat, delete the old war and expanded war files and place the new war 
and startup tomcat again. We constantly get irked by the fact that if a bug is 
on production we have to wait until the evening to patch it whereas our ASP 
coutnerparts can so easily hot-patch. We also use JSP precompilation to improve 
performance so it's not so easy to patch JSPs either.

REMY
I hope hot deployment and redeployment is a reality. However, there are issues
when the webapp tries to interact with some services which reside in the system
classloader (logging here). Packaging webapps a little differently could solve
the problems for now.

YOAV
Allistair, I'll be glad to continue this discussion on the mailing list and try 
and explain why I think reloading an app in-place has only limited usage in production 
environments.  This (Bugzilla) is not the right forum for 
discussions.

RE: Can Tomcat be configured to be an FTP Server?

Yes, in theory you are right, but practical you have to 
write a ServletContainer which is FTP aware; not a simple 
task as FTP is not a simple protocol.

Take a look at a new Apache project: FtpServer at 
http://incubator.apache.org/projects/ftpserver/.

What are you trying to do?

I've a similar need, but it would be helpful if I could hand off
uploads/downloads to an ftpserver.

My concern is timeouts with large file transfers, which I believe
ftp to be better suited?

It may not be very common, but I guess this is not unusual.


regards DaveP

GZip compression in 4.1.27 ..

[Ben Bookey]

Dear Ladies and Gentlemen,

This is a follow-on for a question from last week, but as its now on a
"different-page" of the mailing list. I decided to
post another new questions, so no-one misses it.

1) Below is an original extract of my tomcat 4.1.27 server.xml.  I want to
enable compression in my HTTP connector.
I have a customer with v. low bandwidth. I have read the Apache readme
http://jakarta.apache.org/tomcat/tomcat-4.1-doc/config/coyote.html on this,
but I am still not 100% clear.


Would I be right in understanding that *ALL* I need to do (in the case of TC
4.*) is add the following attribute compression="on" ???







2)  Any suggestions on a way of testing this in our high bandwidth
environment first ?

regards

Ben

Sv: Webapp don't start after shutdown

[Roland Carlsson]

Hi again!

I found out why tomcat is using the path of my workstation instead of the
server as context path. It is a feature of Netbeans to put a file in the
Manifest-folder of the webapp with the path to the files and contextpath.

So it turns out that it had nothing to do with tomcat behaving strange.

Sorry for the trouble

Regards
Roland Carlsson
