JAR Files not found from /WEB-INF/lib

It appears that weblogic server (6.1 SP2 I believe) is not finding all
the jar files in the /WEB-INF/lib directory. Some, but not all. I am
not using a WAR file, the dirctories are right on the disk. I start
out with the following jar files in my WEB-INF/lib directory:
Volume in drive C has no label.

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

in WEB-INF/lib location.

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.

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>

Images not loaded from WEB-INF/lib/images.jar

The images are found in root/images/*.gif, but not
when jarred up and placed in the lib folder. I've looked everywhere
for a solution but all I've seen is suggestions of other places to put
the folder, or to add it to the classpath.
The jar is being loaded but the images are not found. Or at least the images are not showing up - the table where the main image is linked expands to the size of the image when the path is correct.
Does anyone know the solution to this problem? I don't want to just leave them in the folder at root level, because this does not work if I set a default url pattern for the control servlet.
Thanks,
Greg

Thanks,
GregIf your planning to make the images accessible by normal html tags - img etc, then they cant be in a jar, and they must be in a location from which the container serves content - i.e not under WEB-INF. Unless you want to write a special servlet which does nothing but read the images and feed them to the client - but I wouldnt recommend that.
Sounds like your using Struts, and sounds like youre not using weblogic since you wouldnt be able to serve even jsp�s (using forward) from under WEB-INF if you were. Putting jsp�s under WEB-INF sounds like such a good idea when using Struts, but in practice...

Tomcat6 does not load class files from WEB-INF/lib/myjarfile.jar WHY???

I have placed my jar file in c:\tomcat6\webapps\my-application\WEB-INF\lib\myjarfile.jar
But, after restarting tomcat6, when i try to import the class file contained in the myjarfile.jar in a servlet, it says
ProcessFileUpload.java:4: package test.test1 does not exist
import test.test1.*;
^It clearly tomcat's class loading problem.
As i unzipped my jar and placed the packagefolder structure to
c:\tomcat6\webapps\my-application\WEB-INF\classes\testand it works perfectly.
Anyone knows its workaround? please suggest if any configuration changes is required in tomcat or so.
Thanks.

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.

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.

Class not found in web-inf/classes folder of war file within ear file

Hi all,
          I am using Weblogic 8.1 sp4. I have a war file within an ear file. I am trying to deploy the war file with a few classes within its web-inf/classes folder, however when the classes are in that folder I consistently get a class not found exception when trying to instantiate them. If I package the classes in a jar file and then put that jar file within the web-inf/lib folder of the war, the classes are also not found.
          If I put these two classes in the app-inf/classes folder of the ear file, everything works as expected and the classes are found.
          Any ideas of why this is happening. This seems to be a very simple thing that should work, but appears to not be working at all.
          thanks in advance for any suggestions or ideas.

Hi,
          This is a known limitation/issue with WL. There is also no way around this.

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.

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.

Classes are not loading from WEB-INF/classes directory

I have also tried to execute the application by creating a jar file and put it in the WEB-INF/lib directory. But I am getting same result.
Is it the problem with Tomcat configuration? When I gone through Tomcat documentation, I get to know that the WebAppX class loader in Tomcat, loads application specific classes for a web application. Is it possible to start/stop WebAppx classloader manually?
Please help me to solve this issue.
Many Thanks,

Thanks for your reply, Soultech2012.
<%=new com.flt.Test().hello()%>is the only code in the JSP page. Just a single line. Nothing more than that.
The code in Test.java is as follows:
* To change this template, choose Tools | Templates
* and open the template in the editor.
package com.flt;
* @author Francis Lukose
public class Test {
    public static String hello()    {
        return "hello";

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.

Tricky - PDF file not Opening from Web Browser based application

Hi Guys,
Just a brief history about the issue:
At my client site everything was fine when IE7 was there and everybody were able to open PDF files from web applications in browsers. But after a IE8 upgrade, things changed and customers are facing problems. All are Windows XP SP3 machines
Issue: If they try to open a pdf file from the browser it just stucks at 0% and hangs with "Cancel" button. Even if they try to save that file it tell downloading and hangs again in the screen without downloading the file.
Initial fix:
Open Adobe Reader
-> select the menu "Edit"
-> select "Preferences"
-> select the Category "Internet"
-> set the indicator "Display PDF in browser"
-> Reboot the machine
This fix worrked for some people but many user are still experiencing the same thing even after changing the setting many times.
Friends, Is there anything else might be creating the trouble here. Please let me know, and why it is that for some systems it is working and for it is not ?
Thanks,

There was a browser bug with IE in the past that seemed to span several browser versions. It had to do with the interaction of the browser and the webserver. The short version is that I had to toggle the caching option on the folder.
Here's what I ended up doing for my client:
Move their PDF documents into a subfolder called forms and all Flash animations into a subfolder called flash
Marked all folders in the site to "Expire Immediately" (IIS -> highlight root folder -> Properties)
Individually marked the "/forms" and "/flash" folders to toggle this caching option
In this way, it allowed dynamic pages to deliver non-cached content (from the server's perspective) and it allowed binary downloads like Flash animations and PDF files to work as expected without errors. The bug has to do with the cache-negotiation handshaking that goes on between the browser and server.
This may not be what you're seeing but it's good to remember because I've seen it often: the settings that you'd use to optimize a web applications don't seem to work for binary downloads like a PDF document.

Aspects Developer "Verifier jar file not found error"

Hello all.
I'm working in a Java Card project and I have some troubles.
When I tried to compile, verify and load my solution in Aspects Developer's Software, I achieved the following error message: " could not found Verifier jar file".
So I couldn't test my applet nor simulate it.
Then I compiled myself (with Java Card's commands) and execute the verifier file provided with Java Card, and all was good, so i decided to test my java card applet on the simulator or the real card, both with Aspects Developer SW.
Then the error I got was "Read past end of stream".
What am I doing in the wrong way?What can I do test my applet in a Simulator?
Thank very much for your help.
Regards.
Mike L.

Hi,
This error message indicates that an incompatible version of the Java JDK is being used with Developer.
The release notes distributed with Developer are a little misleading. Currently Developer supports Java JDK versions greater than 1.2.2 but not 1.4.x. For example, I have JDK 1.3.1_06 installed on my machine.
Developer currently supports JavaCard development kit 2.1.2 and this specification restricts the versions of JDK that can be used. For more detail look at JCDevKit_User_Guide.pdf which can be found under <JAVA_CARD_INSTALL_DIR>\java_card_kit-2_1_2\doc\en\guides
Cheers,
Alasdair

Classes in JAR file not found

Okay, so I am somewhat new to Java, and I've never used a JAR file before. However, I need to make an applet with access to the local machine, so I've got to put it in a JAR file so I can sign it and blah, blah, blah . . .
Anyhow, my understaing is that I write
<APPLET
CODE = DisplayClass.class
ARCHIVE = display.jar
HEIGHT = x
WIDTH = y>
</APPLET>
then use java.sun.com's html converter to make the tag like


<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
WIDTH = 800 HEIGHT = 450 codebase="http://java.sun.com/products/plugin/1.3/jinstall-13-win32.cab#Version=1,3,0,0">
<PARAM NAME = CODE VALUE = DisplayClass.class >
<PARAM NAME = ARCHIVE VALUE = "display.jar" >
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.3">
<PARAM NAME="scriptable" VALUE="false">
<COMMENT>
<EMBED type="application/x-java-applet;version=1.3" CODE = DisplayClass.class ARCHIVE = "display.jar" WIDTH = 800 HEIGHT = 450 scriptable=false pluginspage="http://java.sun.com/products/plugin/1.3/plugin-install.html"><NOEMBED></COMMENT>
Man, you need a new browser, one that can display applets
</NOEMBED></EMBED>
</OBJECT>


In any event, whenever I try to view it, with either IE or Netscape, the browser can't find the .class file in question.
The JAR file contains all the classes in the base directory. I'm really at a loss as to what I'm doing wrong, since all the docs I can find seem to indicate this should work.

What's all this about DisplayClass.class being in a
package? It was my understanding that classes are
always part of packages. DisplayClass.java (the
uncompiled DisplayClass) certainly refers to itself as
being in a package, with the first line being package
testapplet;So your DisplayClass is in the package testapplet. Then you have to move DisplayClass in a folder named testapplet, or compile as
javac -d . DisplayClass.java
which will then create that folder for you and place the class file inside that.
The jar file should then keep the class in the same folder structure
testapplet/DisplayClass
And your CODE tag should refer to
testapplet.DisplayClass
If you didn't add the package statement to your DisplayClass.java file, then it would be in a default package and you wouldn't have to place the class file in a folder.
