EAR has WAR has JAR in WEB-INF\lib NoClassDefFoundError

What a nightmare.
I found approximately 40 forums on this topic (and there are probably more), but noone has the definitive answer!
Here's the problem....
My servlet uses a utility class that resides in some other jar. That jar is then placed into the WEB-INF\lib directory of the WAR which in turn goes into the EAR. This is supposed to be all that is needed in order for the utility class to be found on the classpath.
In fact, if you run the war in Tomcat as a standalone WAR it does in fact find it.... its when in an EAR deloployed to app server that the problem arises.
I have had no luck with using any combination of putting the jar ANYWHERE in the EAR or WAR no matter if I specify the Class-Path: in the manifest(s) or not.
I thought maybe that I was missing some config in the application.xml or web.xml but I couldn't find anything to support that.
Maybe its dependent on the app server? I am using Orion, but the same problem can be found on J2EE RI release 1.3
Work arounds:
1. Simply put the utility jar in the lib directory of the server you're using
2. Add an ejb module to the application.xml naming the utility jar as the ejb jar. Of course this is NOT an EJB jar and error messages/warnings will appear accordingly, but on Orion at least, it will load the classes needed... hooray!!
Anyone got a definitive answer?

What did you do to resolve this issue .. I'm having the exact same problem.

Jars in web-inf/lib not in classpath

          Hello,
          I am building a web application where I wish to use third party jars.
          (specifically cos.jar and log4j.jar)
          AFAIK when you place these jars in the web-inf/lib directory of your application
          they should then be included in the application classpath.
          However this does not seem to always work. I am using Weblogic 6.1, no service
          pack.
          Eventually I got it to work by adding a manifest to my EJB jar file with the classpath
          pointing to the jars and including the jars in the ear file.
          Has anyone else had any issues with this?
          Thanks,
          James


James,
          Yes, I've had troubles with WLS 6.1.2 finding the classes in my jar files
          that are stored in WEB-INF/lib when deploying as a .war file. The funny
          thing is that when I deploy to a WLS 6.1.0 running on two other machines
          (one solaris, one linux), I don't see this problem.
          My servlets all extend the webmacro WMServlet class, which is found in
          WEB-INF/lib/webmacro.jar. When deploying my web app, grems, I see the
          following behavior.
          On WLS 6.1.0 (running on solaris), the server unjars the WEB-INF/lib files into
          ".wlnotdelete/WEB-INF/_tmp_war_myserver_myserver_grems". That directory
          contains a jar file for each one in my .war files WEB-INF/lib directory.
          On WLS 6.1.2 (running on Solaris), however, the server just doesn't seem to do that.
          Instead, it creates
          ".wlnotdelete/WEB-INF/_tmp_war_myserver_myserver_grems/WEB-INF/lib". Not
          only that, but it doesn't put any of my jar files into that directory.
          Notice that it create the WEB-INF directory twice for some reason.
          Needless to say, any class which uses a class from one of those jar files
          bombs spectacularly with a ClassNotFound exception. This is extremely
          frustrating and any help would be greatly appreciated.
          Thanks,
          Bobby

Deploy problem with ejb jar in WEB-INF/lib

Please help with : StringIndexOutOfBoundsException
On WL 6.1 sp2, I have one EJB jar that deploys fine in an expanded EAR structure,
this has EJB jars and the web apps together running under a single JVM.
But when I need to deploy the Web App to a separate server & JVM, still using
WL 6.1, and leave the EJBs in another WL server I get java.lang.StringIndexOutOfBoundsException.
I have about 8 ejb jars. When I put one of them in the Web-App's WEB-INF/lib directory.
I get java.lang.StringIndexOutOfBoundsException when it starts up, just after/during
the extracting of classes for the standalone Web App. The exception stack trace
mentions manifest, but the manifest for the ejb jar is just standard. It doesn't
even have a Class-Path: entry, which all the others happen to have. an needs
to contain the server EJB jars.

WebLogic 8.1 SP6 NoClassDefFoundError for jar in WEB-INF/lib dir (Solaris)

Hi,
I am getting a NoClassDefFoundError for a class that is contained in the WEB-INF/lib folder of my ear/war file.
The strange thing is that this only fails when i try to deploy to production. In UAT (also on Solaris) and in Windows (test) the exact same versions of the deployment / ear file everything seems fine and the class is accessed.
When i added the jar file to the classpath i experienced a "Unsupported major.minor version...." of this class error so i am reluctant to go down that route and anyway would rather consistent deployment between the systems.
I would REALLY appreciate any suggestions as to what might be the cause or what i could try.
Thanks,
David

Thanks for your replies. Sorry if i didn't post enough information for you...
I appear to have found the problem (i managed to recreate in Windows) but have no idea why this is occuring.
In the startManagedWebLogic.cmd file, if i specify "set JAVA_OPTIONS= xxxxxx" then the system will not pick up this one jar file. This appears to be the case even with "set JAVA_OPTIONS=-Dweblogic.attribute=value -Djava.attribute=value" which i assume is a default value as i can't remember having set it... The moment i comment out this set JAVA_OPTIONS line then the system is able to find the jar file.
(Answering your questions:
- The class in question is being referenced from another class also contained in a jar file in the WEB-INF/lib directory
- the WEB-INF is part of the WAR which is contained in the EAR which is deployed on my server)
For now i am ok but know that in a future build i am going to have to use the JAVA_OPTIONS parameter so would really appreciate any suggestions as to why this might be happening.
Thanks,
David

Project librarys not included in WAR file with deployment (WEB-INF/lib)

Using JDeveloper 9.0.5.2
Project Libraries are not included in WEB-INF/lib when deploying. Although the files are selected in the deployment file at 'Contributors'. Within the 'filter' the .jar files are missing.
To solve it i have to register again (i have already made the librarys project library's) the files within Tools->ManageLibrarys as user library's.
The other workaround is to make the library's System Library's within the project.
In my opinion it is a bug that you must include the project librarys as user librarys within the 'LibraryManager'

Unfortunately no, the issue with output folder being ignored occurs only with example apps bundled with Workshop product.
You can try the following workaround:
- In Workshop, Project > Properties - Java Build Path, switch to Source tab - "Remove the source folder listing" - Click OK and dismiss Properties window.
- Project > Properties - Java Build Path > Source Tab, add the same source folder entry - Click OK
- Export as WAR
With this you should see the class files bundled under output directory structure (Ex: WEB-INF/classes).

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

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:

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.

NoClassDefFoundError with jar in WEB-INF/lib

Hi,
I have an enterprise application running on Websphere 6. I have one external jar file in WEB-INF\lib (it's commons-lang). I am getting NoClassDefFoundError when trying to use classes in this jar file from the web app -- I thought that it was sufficient to drop the jar in \lib and then it would be picked up but obviously that is not the case.
As a workaround, I've created a shared lib on the app server for this jar, and added it to the application. This works fine, but I can't understand why is should be required.
Shouldn't it be sufficient just to put the jar file in WEB-INF\lib under the webapp?

I think Websphere 6 already includes commons-logging. So the error you are getting may be classloader confusion, which is easy to do with Websphere and hard to understand (so I may be confused here). Try not including it anywhere, not in your web app and not whatever it was you did to make it work. Restart Websphere and your web app and see what happens.

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.
          Rex


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
Developers Guide
10g Release 3 (10.1.3)
Part No. B14433-01
has a chapter (3) entitled Utilizing the OC4J
Class Loading Framework which contains a section
entitled Troubleshooting Class Loading-Related
Problems in OC4J.
Thanks for the link, I went through it thoroughly in trying to fix my problem.

Jars extracted from WEB-INF/lib in JDev 9.0.3

I have a project for a Web application with Struts and I've built a deployment profile for it. When I deploy to WAR or EAR the generated WAR contains the jars from <HTML Source>/WEB-INF/lib folder as extracted classes in the WEB-INF/classes folder and jars in WEB-INF/lib as well. I want to do something so that the jars will be included just as jars and not extracted.
Thanks for help.

I put the jars in the deployment profile in the "WAR File" option from deployment profile descriptor.
When the jars were defined in a separate library entry for my project I put them through "WEB-INF/lib" link under "WAR File" option. Both ways it did the same.
I gave up this and I am using ant but I would like to know if it is possible to do it with deployment descriptor.

JDeveloper 9031 creating WEB-INF/lib/struts.jar

Hello,
I just upgraded to 9.0.3.1 from 9.0.2, and I have a problem where JDeveloper will occasionally create a WEB-INF/lib/struts.jar in my project, causing a conflict with the version of struts I am using (RC2). Is there any way to prevent this? I ended up creating an empty jar and setting it to read-only to stop JDeveloper from placing it's version. Also, I tried disabling struts support, but that seemed to have no effect.
Thanks,
Patrick

Hi.
Hmm, this was a known issue that should have been fixed in 6.1. Please
open a support case on this.
Thanks,
Michael

I have a WAR file which contains

And get an error that a struts class is not found.
I checked 6728 times and it's there :-)
If I explode the war file, all is well.
Other posts allude to this being broken (exploded file
works, war does not fond jars) as of WL6.0SP2.
I'm using WL6.1SP1.
Any ideas?

Wl6.1sp2 can't find classes in WEB-INF/lib

          Hi,
          I meet a very strange problem.
          I use struts in my application.so I put struts.jar in web-inf/lib.
          In the .war file, the struts.jar can be found under web-inf/lib.
          my servlet configuration in web.xml is:
          <servlet>
          <servlet-name>action</servlet-name>

          when this .war file is deploy, the console not show any error message.
          then,when i visit a jsp page that has a <html:form> tag, the console will show

MySql driver not found in WEB-INF/lib

Hello
This topic is very often met on this forum but there are no
suitable answers for the problem I have. I am creating
a Jsf application and I have setup a connection pool using
the MySql jar. I want to supply the jar with the war and I keep
it in WEB-INF/lib directory but I still get ClassNotFoundException.
I am running this on a Debian machine with Sun JVM 1.5,
Tomcat 5.0, Mysql 4.1, Connector/J - nightly build from
20060403 (since the stable version has bugs with Charset).
Here are the confings. If I missed some of them, pleaste tell
me.

Not all the rules apply at the same time. I also tried to
setup the mysql jar in ${catalina.home}/common/lib
directory and it was loaded but I need to make it work
in WEB-INF/lib location.

     ... 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.

WEB-INF/lib WEB-INF/classes ClassLoader problem

I have observed that in WL 8.1, a class in a jar deployed in WEB-INF/lib does not have the ability to access a resource deployed in WEB-INF/classes. Is this the intended behavior to not have WEB-INF/lib and WEB-INF/classes in the same ClassLoader? If so, is there a way to configure this behavior to give permission to classes loaded in WEB-INF/lib to the ClassLoader that has WEB-INF/classes?
thanks,
Kenneth Shin

Are you really certain that's what's happening? Is it possible the jar file stored in WEB-INF/lib isn't found elsewhere in the CLASSPATH, perhaps by a higher-level classloader? You might consider setting "prefer-web-inf-classes" to true in your weblogic.xml file, to ensure that the jars in WEB-INF/lib are being used instead of from somewhere else.
