Tomcat 4.1.10 ignoring WebApp's WEB-INF/lib/*.jar

I've been bashing my head against this for two days now:
1. Got a webapp deployed in tomcat, with a whole bunch of jars that sit in the /<webapp>/WEB-INF/lib
2. In web.xml, I instantiate a servlet that performs cache-loading - the servlet class is in of the jars from point 1 ^ - and it works fine, finding all the classes that it needs, etc.
3. A test page, with nothing more than a page import directive of the same package that the servlet from point. 2 uses - fails with package {xxx} does not exist...
Any help is GREATLY apreciated!

Thanx for all your suggestions, nothing seems to have solved the problem and since I had it working fine under tomcat 3, I'm quite convinced that this is a bonafide bug.
I'll award 1 duke dollar to each, since none have solved the problem.

Unable to delete WEB-INF\\lib\*.jar using ant

Using ant to build struts.
This is part of the build.xml for struts-example.war
<property name="deploy.dir" value="${tomcat.home}/webapps"/>
<target name="cleanWebApp">
<delete file="${deploy.dir}/${war.file.name}" />
<delete dir="${deploy.dir}/${war.file}" includeEmptyDirs="true" />
</target>
But when I try to build and reload it to tomcat, it gives me errors:
cleanWebApp:
[delete] Deleting: D:\jakarta-tomcat-5.5.7\webapps\struts-example.war
[delete] Deleting directory D:\jakarta-tomcat-5.5.7\webapps\struts-example
BUILD FAILED
D:Java\code\struts\strutsexamples\build.xml:46: Unable to delete file D:\jakarta-tomcat-5.5.7\webapps\struts-example\WEB-INF\lib\commons-digester.jar
Also lib\struts.jar(maybe more) can't be deleted.
Now I have to stop tomcat, delete it manually, and reinstall the war.
How can I fix this problem?

All the advice above seems to make sense, but .....
- Tomcat shutdown,
- with all java processes shutdown,
- after a full reboot,
- with antiJARLocking="true" set in every context.xml I can find:
[delete] Deleting directory C:\Program Files\Apache Software
Foundation\Tomcat 5.5\webapps\myApp
BUILD FAILED
C:\myApp\build.xml:118: Unable to delete file C:\Program Files\Apache
Software Foundation\Tomcat 5.5\webapps\myApp\WEB-INF\lib\antlr.jar
But I CAN delete the jars using the normal Windows Explorer or from the DOS Command Prompt.
And per the advice found here:
http://saloon.javaranch.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic&f=67&t=000574
I've downloaded the Process Explorer from www.sysinternals.com and no windows processes appear to have a handle on there directory.
I think the solution is indeed to exclude jar files from <delete> target.

Working with tag-library which is packed in WEB-INF\lib\jar-file.jar:

Hi,
When importing a webworks war file, which contains default taglib.tld in the webworks.jar which is packed in /Web-Inf/lib/webworks.2.1.7.jar the war file.
I am getting following error while running the jsp.
Error(6): duplicated tag definitions within the same TLD: text
Error(6): java.lang.NullPointerException
Error(6): Unable to load taghandler class: /webwork
Line which points to Errors is "<%@ taglib prefix="ww" uri="/webwork" %>"
But, There is a taglib.tld in /Web-Inf/lib/webworks.2.1.7.jar!\meta-inf\tablib.tld
which mentions uri as
<taglib>
<tlib-version>2.2.1</tlib-version>
<jsp-version>1.2</jsp-version>
<short-name>WebWork Taglib</short-name>
<uri>/webwork</uri>
</taglib>
But, There is no following entry for '/webwork' (uri) in web.xml
Same war is working fine in tomcat webserver.
Can anybody explain me how to work with this kind of a setup, where taglib is packed in some jar which is packed in Web-Inf/lib dir.
Thanks,
Siva

I found the problem. The web-app was finding the class in the APP-INf/lib. But the problem was being caused due to a reference to another class that was being loaded by the webapp classloader which was not visible to the class inside the common jar. The solution was to make sure both classes were being loaded by one class loader.
Thanks anyway

OAS 10.1.3 isn't detecting /WEB-INF/lib jar files within WAR file

Hello,
I have been developing and testing a simple non-EJB web application on Tomcat 5.5 with no class loading difficulties for the past several months. All of the needed JARs for my app are located under the WEB-INF/lib directory. My next task is to deploy the WAR file containing my webapp on the Oracle 10g (10.1.3) application server.
The problem I am having when trying to do this is that when I deploy the WAR file from Oracle Enterprise Manager, the WAR file will expand correctly but at runtime OAS doesn't appear to be detecting the JAR files in the WEB-INF/lib folder of my WAR file. I have confirmed that the JAR files are indeed being expanded in the directory that OC4J expands the WAR file into:
appserver/j2ee/home/applications/appEARFile/MyWebApp/WEB-INF/lib.
But when I run the application, from the Firefox browser I immediately get the following 500 Internal Server Error:
"Servlet error: Error instantiating servlet 'reports'. Servlet class org.springframework.web.servlet.DispatcherServlet not found in web-application MyWebApp"
(The IE browser just gives me the 500 error without additional elaboration.)
But my spring.jar where that class is located is in the WEB-INF/lib directory. Does anyone have an idea what the solution is--how can I get OC4J to read the spring.jar (or any jar) in that lib folder? (Or is there a way I can configure logging to better pinpoint the problem if that isn't it?)
Thanks,
Glen

Glen,
You said:
IE browser just gives me the 500 error without
additional elaborationTry unsetting the "Show friendly HTTP error
messages".
From the "Tools" menu of Microsoft Internet Explorer,
choose "Internet Options".
(You should then see another window entitled
"Internet Properties" displayed.)
Select the "Advanced" tab and search for "Show
friendly HTTP error messages".
Excellent--that worked. Thanks! I was afraid that I would have to be debugging on Firefox exclusively.
I also suggest setting the
"search-local-classes-first" attribute, of the
"web-app-class-loader" element, in your
"orion-web.xml" file to 'true' (if it isn't
already).
That did it. My orion-web.xml file was of the old DTD-based version, I believe that was causing the problem.
The following document:
Oracle® Containers for J2EE

Bug using WEB-INF/lib Jar archives

Hi, I am running iPlanet 6.0Sp3 on Windows 2000. I deployed our Web
application in the form of a War file and it is now under the APPS/modules
directory as the following directory: APPS/modules/ourapp.
When I start the iPlanet Application Server, it fails to find any of the
classes in the Jar files in APPS/modules/ourapp/WEB-INF/lib/. Is this a bug?
One workaround is to unjar all of these files, but this is counter to the
J2EE spec. Another workaround is to modify the classpath in the iPlanet
registry, but this would expose the classes to other Web applications
running in the same server.
Thanks for any help. Martin

Hi Martin,
I think you are packinh up the jar file inside the war module, as far as i know
there should be no jar file inside the module/App-name dir tree.
all the modules either war or jar should be in <GX_ROOT_DIR>/JAR dir.
So try making the war module with class files only(static content can also be
added) with appropriate deployment descriptor.
I will mail you separately the procedure for creating a war file from deployment
tool gui.
Please mail me back if you have any other problems.

WEB-INF\lib\ Jar files

Hello
I have a war module with this:
/index.html
/pages/ (my pages)
/pages/js (my js)
/pages/images (my images)
/WEB-INF/classes/ (my servlet classes)
/WEB-INF/lib/ (my lib jar files)
/WEB-INF/web.xml (descriptor)
ok,
I run deploy tool,
open this war file (module), (ex mod1.war)
convert to ias module, modify the descriptor,
verify (everything ok)
save module
create ear (ex ap1.ear)
put this module within this ear
create and save ear descriptor
save ear
verify (everything ok)
deploy ear.
ok,
Why decompress my lib jar files in:
/APPS/ap1/mod1/WEB-INF/lib
These wil be fine if decompress the entire jars, but only extracts the class
files and no the xxxx.properties neither messages.txt; exactly
no extracts files that aren't .class. ???
Are there any workaround to this that isn't copy the files? Figure not to
have ftp acces in a sun? What we have to do?
Thanks.

In iWS 6.0, the context information such as a context path of the web application and other properties are defined in web-apps.xml file.
'class-loader' element in web-apps.xml file can be be used to specify the class path to a web application and customize how the application is serviced.

Web application can not find apphome /WEB-INF/lib/*.jar files in classpath?

I need to add the jsse jars to one of my servlets. I do not want the jsse in the server classpath(jvm12.conf) however, because this screws with some credit card jar I am using. Can't I have a per application classpath with the /WEB-INF/lib directory? This is iWS 6.0.

WL 5.1 war: can't access WEB-INF/lib jars

          I'm trying to deploy a war file that uses Struts on wl5.1. The problem I am having
          is that the servlets are unable to find classes from jars in the war file. If
          I put the jars in the weblogic classpath, it works, but I'd rather not do that.
          This war file works on Tomcat, but it doesn't seem to be working on wl5.1. Oddly,
          while deploying, the server finds the servlet class itself from one of the jars,
          but then can't find the other classes the servlet class references, even though
          they are in the same jar.
          I've verified that the servlet class is not in the server classpath. I've found
          a number of posts about this problem in this newsgroup (though generally for later
          versions of the appserver), but none of them solved my problem.
          If anyone can recollect Weblogic 5.1, I'd appreciate your help.
          Thanks.

MySql driver not found in WEB-INF/lib

Hello
This topic is very often met on this forum but there are no

     ... 60 moreI don't really understand how I can setup the CLASSPATH in this
context. So there should be something else. Does anyone have an
idea?
Thanks.

This is what I achived using the <metainf> tags from
war task in build.xml. Look at the first code
listing. The
magic code is:
<metainf dir="${meta.dir}">
<include name="context.xml"/>
</metainf>where ${meta.dir} is defined as ./meta and there
resides
the context.xml file (look at the project layout).Very good, thanks.
Any guesses why Tomcat is not loading mysql jar from
WEB-INF/lib directory?No. 8(
My understanding is that JARs in the WEB-INF/lib are visible only to your web app. Those in /common/lib are visible to all apps and the container. Those in /server/lib are visible only to the container and no apps. It SHOULD work from WEB-INF/lib. I've done it that way, but it was an older version of Tomcat.
Checked the Tomcat docs. They say to put it in /common/lib, but they don't explicitly forbid it in WEB-INF/lib.
I'll try a simpler example.

Is there a restriction on loading "javax" classes from WEB-INF/lib?

I'm having trouble with a webapp in WL 10MP1 that is having trouble loading classes from the "jsr311-api-1.0.jar" in my WEB-INF/lib. Even though I have no trouble with it in Eclipse (no compile errors), classes from that jar fail with "NoClassDefFound" exceptions. I have a feeling it might be the fact that the packages in that jar start with "javax". Assuming that's the case, is there anything I can do to fix this?
What's even stranger is that the errors I get are when I try to load them directly from the Spring context. However, if I remove the test references to those classes, there's other code that loads those classes later in the application startup (after the Spring context finishes loading), and they load perfectly fine (I turned on verbose class loading to verify this).

Note that I've tried two other strategies that both result in the same failed state.
I tried putting the "jsr311-api-1.0.jar" in $JDK_HOME/jre/lib/ext, but that causes a failure to find Spring classes. I then copied the "spring.jar" into $DOMAIN_HOME/lib, and then it fails to find CXF classes. After doing the same with "cxf-2.2.3.jar", it then fails to find "javax.servlet.ServletContextListener", which clearly tells me there's no benefit to this approach.
Similarly, I tried copying the jars into $DOMAIN_HOME/lib, and that fails to find "org.apache.commons.logging.LogFactory". I could continue down this path, but it doesn't seem likely to succeed. Eventually, I'll get to a point where it just can't find the classes specific to my application, which I certainly can't copy into $DOMAIN_HOME/lib.
The first basic problem is that I can't put anything into a higher-level classloader that will eventually reference classes in a lower-level classloader, because references can only go up the chain, and the second problem is that WebLogic appears to ignore classes in WEB-INF/lib in the "javax.*" packages. I think there might be an exception for "javax.xml.*", but not for other subpackages. I tried adding a "prefer-application-packages" clause to my weblogic-application.xml file, but that had no effect.

Any ideas what I'm doing wrong?
Thanks,

Found the solution...
The deploy directory needs to have a temp directory in
it!!!!We have had this problem too when upgrading to 4.1.27 but are confused about which directory should have a temp directory under it, and what the permission should be. Could someone enlighten us ?
Thanks

How to load .jar files of subfolder in web-inf/lib folder?

Hi All,
In 'webapps\myappliction\WEB-INF\lib\myfolder' and in myfolder have some .jar files. How to load subfolder jar files in weblogic server 10.0?
Do I need to configure subfolder jar path in web.xml? Please help me.
Thanks & Regards,
Gangadhar

Class loaders associated with a Web application can be configured to locate local classes first. To enable this we have to set the <prefer-web-inf-classes> to true in the deployment override weblogic.xml, for example
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
