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.

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.

Bug:WEB-INF/lib JARs not added to runtime classpath of WebLogic Server

The JAR files packaged in the WEB-INF/lib directory of an application do not get installed to the runtime classpath of the Weblogic server.

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.

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.
Refer to example web-apps.xml file in Prog. guide to Servlets for more details.

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.

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:

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.

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.

Can we downlod jar from WEB-INF/lib using webstart?

Hi,
Can we down jars which are in WEB-INF/lib directory
using jnlp (webstart)?

I got the basic concept of webstart.
I can download jar only if publicly accessible (It
should form a valid URL).Note an important distincion here..
1) It is possible to form valid URL's that
point to WEB-INF/lib.
2) The server should not allow access, to
that URL (any URL pointing inside WEB-INF/lib)
and should return instead the HTTP code that says
'not allowed/barred/forbidden'
There is a big difference between a[b] valid URL,
and a valid URL pointing to a forbidden resource.
But yes, you seem to understand correctly,
that the jar's for web-start cannot be loaded
back to the client, from this directory.
Thanks for your help.You're welcome.

I wrote up a simple test case for this and it works fine for me.
I suppose there are diffences. ;)
I am using:
WebLogic Server 7.0 SP1 Mon Sep 9 22:46:58 PDT 2002 206753
Take the attached zip, unzip.
cd to directory
ant build
then deploy it via the console, or
java weblogic.Deployer -adminurl t3://127.0.0.1:7001 -user weblogic -password
weblogic -activate -name mywebapp2 -source e:/weblogic/dev/sandbox/griffith/apps/output/exploded_mywebapp_lib/
Then:
http://c863775-d:7001/exploded_mywebapp_lib/frobber
works for me. My servlet implments an interface in the jar in my lib dir.
Cheers

WLS 6.1sp3 classloader loads all archives within WEB-INF/lib/*

          Within the lib directory of my webapp, I have several different versions of myarchive.jar.

          myarvhive.jar_bf_2.5release
          In WLS 6.0 this method of storing the previous archive version was safe. However,
          now after implementing WLS 6.1, I only can have the current archive release within
          the lib directory. If the previous versions are store within the lib, old methods
          are used.
          I do not understand the WLS classloader behavior and why is it different from
          WLS 6.0?
          wls- WebLogic Server 6.1 SP3
          platform- OSF1 localhost V5.1 1885 alpha
          jvm- Classic VM (build 1.3.0-1, native threads, jit)


          Within the lib directory of my webapp, I have several different versions of myarchive.jar.
          In WLS 6.0 I would keep older version within the lib directory but renaming them
          so that the current release would get loaded.

Please help.! Problem with locating classes within Jars under WEB-INF/lib.

Hi All,
I have a problem which you guys would have faced already...Here it goes..
I'm using OC4J 10.1.3.0 and use ADF for my web page. I have a controller class which refers to JSF/ADF APIs and this class is archived as a jar file and put under WEB-INF/lib, Also, all the classes related to JSF/ADF are available under the same WEB-INF/lib folder.
When I invoke my page, the controller class is getting called but it throws NoClassDefFound Error for the ADF based class. i mean, these ADF/JSF classes are not getting found when my jar class is placed within WEB-INF/lib. However, when i extract my jar into WEB-INF/classes, it works.
I'm sure, i miss some entry for classpath somewhere. Can any one please point me to right direction...?
Thanks
Rajasekaran

Hello,
I do not have a direct answer to your question, but could you try the ClassLoader query tools to see if your classes/jar are loaded by the applications:
