Classes not picked up from WEB-INF/classes

9ias R2: OC4j
Some classes could be found from WEB-INF/classes by JSP pages but some others could not.
WEB-INF/classes is part of the classpath in JSP's point of
view.
And if explicitly import the class such as
import abc;
in JSP pages and the class could be found.
Anybody has any idea? Or anything wrong I am doing?
Thanks!

Classes are not loading from WEB-INF/classes directory

Hi All,
I am in a deep troble because the class files in the WEB-INF/classes directory are not loading.
I have deployed the application in Tomcat 6 server. And stored all class files under WEB-INF/classes dirctory. But when I execute a JSP page, I am getting following error:
HTTP Status 500 -

     javax.servlet.http.HttpServlet.service(HttpServlet.java:803)The classes are available in the WEB-INF/classes directory and the folder name and package name of the classes are correct. 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,
Francis Lukose

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";
}Many Thanks,
Francis

JAR in a WAR Classloading a .class from the WARs web-inf/class

A little backround on my environment:
I have a jar that contains some common functionality (common.jar) that is shared among all my web apps. There is a scheduler function in the JAR that queries the applications datasource for schedules to run. Each schedule contains a class that implements the interface ScheduleCommand and has an execute method. The ScheduleManager get the list of schedules from the db and uses a classloader to load the schedule command and call the execute method.
ScheduleCommand cmd = (ScheduleCommand) Class.forName(scheduleCommands.getClassName()).newInstance();
The issue:
I have some common schedule command in the common.jar like clean temp folder, monitor memory, etc. I also want to be able to include additional schedule commands in the WAR that are unique to that web app.
WAR
--web-inf
----classes
------CustomScheduleCommand.class
----lib
------common.jar
When I do this however the ScheduleManager in the common.jar is not able to find the CustomScheduleCommand.class in the WAR�s web-inf/classes. Do I need to use a different classloader or do I need to add a classpath to the manifest of the WAR?

Hi Michael,
there are diffrent options to do this, depending on whats needs to be achieved.
a) Easiest way (but only possible, if no action has to go back to your template): Create an RRI-Jump-Target to your ABAP report
b) Also only possible when no additional interaction on your template has to take place: Create a bsp and call the bsp when clicking on the button. Advantage in comparison to a) you could get a new window with for example a sucess or error message
c) Use an own helpservice class. Now this as you have seen can get more complex, as interaction with your webtemplate can take place. In principal you need to create a class inherit from cl_rsr_www_help_window and overwrite the process_cmd method. Now you can paste your coding inside and you are finished (when you register the help service class to a web item).

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.

Thank you gimbal2 . There was error in creating the jar file myjarfile.jar.
But, now I have created it again and placed it in place
c:\tomcat6\webapps\my-application\WEB-INF\lib\myjarfile.jarand tried to use one on the Class file included within the jar to compile my servlet. But, still I am getting error at servlet compilation time. I want to place executable jar files in
c:\tomcat6\webapps\my-application\WEB-INF\lib\myjarfile.jar and compile my servlet and execute the servlet.
I DO NOT WANT TO unzip the jar, placing all unzipped files to
c:\tomcat6\webapps\my-application\WEB-INF\classes\ folder and comiple my servlet and execute the servlet. But, I am failing to user WEB-INF\lib\ folder facility....please help me why i am not getting class files from WEB-INF\lib\ folder.
If you please see the small code bit and tell me any possible error that would be very helpful.

prefer-application-packages and prefer-web-inf-classes not working

Hi,
I'm upgrading to Weblogic 10.3.2 an application that was running quite fine in Weblogic 8. But I don't manage to get it working in WL 10. I'm getting a Class Not Found error (javax/xml/stream/XMLStreamWriter) but that class is in one of the jar files of my application: "<war-file>/WEB-INF/lib"
It seems a class loading problem but I'm using both <prefer-application-packages> and <prefer-web-inf-classes> and it's still not working. This is my weblogic-application.xml:
<?xml version='1.0' encoding='UTF-8'?>
<weblogic-application>
<prefer-application-packages>
<package-name>javax.xml.stream.*</package-name>
</prefer-application-packages>
</weblogic-application>
I'm deploying using an ear file wich contains a war file.

Hi!
We have the jar xbean-2.2.0.jar in APP-INF/lib. That one contains the class javax.xml.namespace.NameSpaceContext. I saw that the same class was in another jar as well. I've removed it from the second jar and now it's only in the xbean-2.2.0.jar. But I still get the same error. Maybe there is something wrong in my application.xml? I have all the jars in APP-INF/lib and in <war-file>/WEB-INF/lib

Custom classes in Web-INF/classes not recognised

          Can any body tell me why classes in WEB-INF/classes directory are not recognised by
          the WebLogic while importing in JSP??
          Thanks in advance


          Hi all,
          we were having the same problem - WebLogic not recognizing custome classes in
          the WEB-INF/classes directory. As soon as we removed the Class-Path entries from
          the WARs Manifest file (and placed the referenced JARs in the WEB-INF/lib directory)
          everything worked fine. It seems as if WebLogic excludes WEB-INF/classes from
          the classpath in case Class-Path entries in the manifest file are present.
          Is there a patch for this? If yes, I'd appreciate your notice!
          Cheers

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.
          Regards,

I've created the "Faces Example" project in Workshop Studio 3.2.0 and it's running fine. However, when I export the war file to run it on another server the class files located at "WEB-INF/classes" are not included with the war.
Any suggestions on what I may be doing wrong would be greatly appreciated.
thks!

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).

WEB-INF/classes not searched?

I am developing an Struts application.
During development I just want to have my Actions and all other files in the projects package strukture, so I compile the classes to the WEB-INF/classes directory and ends up with a structure like
WEB-INF/classes/dk.acompagny.anapplication.viewcontroller.MyAction.class.
I find the compiled class in the directory structure but OC4J does not find it. Instead I get a runtime error like:
SEVERE: No action instance for path /login could be created
oracle.classloader.util.AnnotatedClassNotFoundException:
     Missing class: dk.bladkompagniet.plus100.viewcontroler.LoginAction
     Dependent class: org.apache.struts.util.RequestUtils
     Loader: current-workspace-app.web.Bladkompagniet-Plus100-webapp:0.0.0
     Code-Source: /home/fgjensen/Work/Src/Bladkompagniet/Plus100/public_html/WEB-INF/lib/struts.jar
     Configuration: WEB-INF/lib/ directory in /home/fgjensen/Work/Src/Bladkompagniet/Plus100/public_html/WEB-INF/lib
This load was initiated at current-workspace-app.web.Bladkompagniet-Plus100-webapp:0.0.0 using the loadClass() method.
JDev lists the path it searches an the WEB-INF/classes directory is not listed. However, it finds my jsp pages and the default behavior of OC4J should be to search the WEB-INF/classes path.
Am I missing some configuration set?

Forget it, I found the error: I have to learn to spell!

WEB-INF/classes not in classpath issue - bug or specification?

I've noticed BC4J expects some of its configuration files to be present in the standard classpath or the application.
However, when running web-apps, the WEB-INF/classes are used for loading classes by the JVM, but they are not in the classpath literaly which causes BC4J not to find its metadata files - this has caused many people to be confused because they believed (like me) that the /classes folder is just another part of the classpath.
But someone has to solve this! After all, if I have a million web-apps, I (as a BC4J user) do not want to include a million JAR files in the classpath. I want to put the JAR in the classes directory and have BC4J find it automatically since its part of the web-app's classes, jars/zips and such.
The question is, is this a BC4J issue (not finding the files) or a Java Specification issue? and if this is a mere BC4J issue, why won't Oracle provide a small patch for BC4J (simply release an updated JAR/ZIP file)? Or instead, put it in BC4J release notes (unless its already there and I've missed it..) so that customers won't have to spend/waste valuable time trying to understand.

===========================================
If I understand you correctly, it sounds like you need to put the bc4j .jar files in the /j2ee/home/lib directory...by placing a jar file there, it becomes available to all web applications running inside OC4J...
does that solve your problem?

Copying files from same directory as *.java files and moving to WEB-INF/classes/ package name

In our current application we have the following source directory structure:
          src -
          - com
          - edeploy
          - subdirs ... (many directories here)
          - jsp
          -subdirs ... (many directories here)
          In com.edeploy.subdirs, there exists *.java files, and *.gxq files (query
          files). I would like to modify my build.cmd script to copy the *.gxq files
          into the same directory as the class files.
          Here's my script so far:
          @REM Create list of files to compile
          DIR /S /B /A:-D src\com\*.java >class.list
          @REM Create list of query files
          DIR /S /B /A:-D src\com\*.gxq >query.list
          @REM Compile
          javac -d stage\WEB-INF\classes @class.list
          @REM Copy query files into class directory
          .......... code needed here ......
          Can anyone help me with this?
          Thanks,
          Matt

prefer-web-inf-classes in weblogic.xml doesn't work

When I try to use <prefer-web-inf-classes>true</prefer-web-inf-classes> it works fine with default classloaders structure. But after I changed classloaders hierarhy by means of <classloader-structure> in weblogic-application.xml classes from web app are ignored and classes from outside web app are loaded.
Here is classloaders structure I use
<weblogic-application>
<classloader-structure>
<module-ref>
<module-uri>mywar.war</module-uri>
</module-ref>
<classloader-structure>
<module-ref>
<module-uri>myejb.jar</module-uri>
</module-ref>
</classloader-structure>
</classloader-structure>
</weblogic-application>
Has anybody encountered this before?

Hi, Rob
Does it work in WL9.2?
It seems I do it exactly as the explained at http://edocs.bea.com/wls/docs81/programming/classloading.html - and it fails :o(.
I try to run my app.ear with WL9.2 There are 2 components in it: webapp and mdb. The webapp/WEB-INF contains weblogic.xml:
<weblogic-web-app>
<container-descriptor>
<prefer-web-inf-classes>true</prefer-web-inf-classes>
</container-descriptor>
</weblogic-web-app>
Mdb is expected to run in the same mode, i.e. to prefer the webapp/WEB-INF/*.jar over the parent Weblogic classloader. To do so I add the weblogic-application.xml to the app.ear!/META-INF:
<weblogic-application>
<classloader-structure>
<module-ref>

<module-uri>webapp</module-uri>
</module-ref>
<classloader-structure>
<module-ref>
<module-uri>mdb.jar</module-uri>
</module-ref>
</classloader-structure>
</classloader-structure>
</weblogic-application>
Now, when classloader-structure specified, both webabb and mdb prefer the weblogic root loader as if prefer-web-inf-classes not defined at all.

Prefer-web-inf-classes Problem

Hi ,
I have an web application war file which has some jsp's and jar files in the lib
directory of the war file .
Also one of the jar files which is of different version is present in the classpath
of WLS .
My prb is that the my web application does not deploy . When the jsp's compile
it uses the jar file (this is if different version from jar file in the application)which
is set in the WLS Classpath rather than the jar file in the war file . I have
set <prefer-web-inf-classes> as true in the web application xml . Also any of
the classes in the jar file does not starts with java. , weblogic. , javax. .
I think at the time of jsp compilation the jar files in lib are never loaded though
preferwebinfclasses is true ... so does this mean that preferwebinfclasses come
into picture only after deployment of application ?
Can any body help me on this ..

Do you know what the patch number is? I just downloaded 10.3 and came across the same error...so I don't think it has been put in 10.3 just yet.
Thanks

Locating the contents of WEB-INF/classes

Hi,
We have a web-app deployed as a WAR file (unexploded) and we want to be able to the contents of WEB-INF/classes (ie properties). However when I try and access these files via a web browser, I receive a 404. I tried putting a simple HTML page in there which also gave a 404. I also tried the same method with a simple dummy WAR and was able to retrieve the HTML opage in WEB-INF/classes.
Is there some setting which allows the contents of WEB-INF/classes to be read, or not to be read?
The java version is J2SDK 1.4.2-05, and the app server is JRun 4 updater 4.
Thanks,
Jon Daniels

No - fundamentally what we are aiming for is to have the unexploded WAR app read properties (i.e. log4j.properties, etc) from the WEB-INF/classes folder. To simulate this I attempted to access properties via a web browser; however I'm not sure that's the best way to test, so to rephrase: the problem is that my WAR-file based web-app is not loading properties files from the WEB-INF/lib classes directory.

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.
