log4j2 in JNLP results Classnotfoundexception

we have an old desktop application which was running on log4j. this application gets deployed using JNLP on the users system and then is connecting to server at our end. we are in the process of upgrading the application to log4j2. we have upgraded the server side code and it works fine. for the JNLP side of code, though we have done all the changes and deployed the application properly we are ending up with an exception which we dont seem to find the cause off. any help here is appreciated..
the exception is as listed below..

the exception point to a class file in the log4j-1.2.17.jar (our old jar). i am sure i dont have the old jar anywhere in the code or any part of the code referring the the old jarfile.
pasted below is the sysArgs section of the JNLP where i am referring to the new properties file

I am not familiar with JNLP, but according to your stacktrace, program cannot find. In Log4j2 package org.apache.log4j was changed to org.apache.logging.log4j. As a result it is not available.
One of easiest solutions in your case - to use Log4j 1.x bridge (Here is Migration guide)
If you want to use current version add to <argument> param to use log4j2 impl (by default it is uses org.apache.commons.logging.impl.LogFactoryImpl configured for log4j 1.x)
org.apache.commons.logging.LogFactory=org.apache.logging.log4j.jcl.LogFactoryImpl

we have found the solution. in our case there were two issues
the jar signing was not proper. the jars have manifest files under the meta-inf folder. the value of this folder was corrupted. we manually edited the file and preserved the original values for everything except the SHA keys and then resigned these jar.
in the log4j2-api jar there is a log4j-character.properties file which was getting corrupted while signing the jar using ant script. after the signing we replaced this file in the jar with the copy of the file saved from before the signing.
above to steps resolved our issue. i know what i wrote above might not make much sense to someone. happy to provide screen grabs in case on demand someone comes across this issue.

Can anyone help?

I was able to get resolve the exception by updating \Oracle\Middleware\user_projects\domains\my_domain\bin\setDomainEnv.cmd with below commands
set JAVA_OPTIONS=%JAVA_OPTIONS% -DUseSunHttpHandler=true -Dssl.SocketFactory.provider=sun.security.ssl.SSLSocketFactoryImpl -Dssl.ServerSocketFactory.provider=sun.security.ssl.SSLSocketFactoryImpl

Fixed this issue by adding following lines in JVM arguments.
-Dweblogic.security.SSL.nojce=true
-Dweblogic.ssl.JSSEEnabled=true
-Dweblogic.security.SSL.enableJSSE=true
Don't forget to recycle JVM. :)

I was getting similar when trying to upload a file to an S3 Bucket on AWS from a WebLogic application. I added the following lines
JAVA_OPTIONS="${JAVA_OPTIONS} -DUseSunHttpHandler=true -Dssl.SocketFactory.provider=sun.security.ssl.SSLSocketFactoryImpl -Dssl.ServerSocketFactory.provider=sun.security.ssl.SSLSocketFactoryImpl"
just before this command
JAVA_OPTIONS="${JAVA_OPTIONS}"
export JAVA_OPTIONS
in
\Oracle\Middleware\user_projects\domains\my_domain\bin\setDomainEnv.cmd
and my issue was resolved. Just make sure to restart WebLogic after the amendment.

Add this in startup params
-DUseSunHttpHandler=true
-Dssl.SocketFactory.provider=sun.security.ssl.SSLSocketFactoryImpl
-Dssl.ServerSocketFactory.provider=sun.security.ssl.SSLSocketFactoryImpl

Could not initialize class javax.crypto.SunJCE_b

I have a Java servlet application developed and on my develpment PC everything works as expected including using SFTP programmatically to copy over a PDF using HTTPS on port 8443 etc and with SSL certificates in place too.
However, when I attempt to run the application on the Live server I receive the error;
java.lang.NoClassDefFoundError: Could not initialize class javax.crypto.SunJCE_b
On investigation, some are suggesting check the jce.jar. But I have ensured the jce.jar is present and also created a "lib" folder in my project and copied the jar there and placed the jar on my build path but still the problem exists.
How do I resolve this please? Thanks in advance. Here is the console output from right after Tomcat has started the application;

The jce.jar must be inside the folder WEB-INF/lib of the deployed web application.

I've seen this problem pop up very often and there seems to be a lot of confusion around it. The actual reason this is happening is because the JRE you are using to run your application has been set up with the unrestricted JCE policy jars inside its jre/lib folder (inside your jdk install folder).
If your current project does not need these, then you can move then out of this folder temporarily. This will remove the requirement on the jce libraries and you will no longer see this error.
Hope this helps.

JAX-WS client fails after redployment via tomcat manager

I have an application acting as a client to a JAX-WS server. The connection works fine if I deploy the application directly by placing the war into the tomcat webapps directory (even if doing a hot deploy). However if I undeploy, then redeploy the application using the tomcat manager (from an automated script) I get the exception below thrown anytime it attempts to establish a connection.

This post showed up here in a search with someone having a similar problem, but had no resolution other than to use spring-ws which isn't really an option for me at the moment.
Has anyone run into this before and been able to resolve the issue? I'm a bit puzzled by what is going on here to make deployment via the tomcat manager different than deploying by placing the files in webapps.

I also encountered this issue. The problem was that I had a dependency on cxf-rt-frontend-jaxws-2.5.2.jar in my classpath, which contains an implementation of org.apache.cxf.jaxws.spi.ProviderImpl that conflicts with the same class in rt.jar that comes with the JDK.
Later versions of cxf-rt-frontend-jaxws no longer contain this class. After upgrading to cxf-rt-frontend-jaxws-2.6.15.jar, the problem was resolved.
I expect that the problem occurs intermittently because the classloader would randomly choose which implementation of ProviderImpl to use each time the WAR is deployed.

In my case, the problem was on SymbolTable class, which was both on com.sun.org.apache.xerces.internal.util.SymbolTable (from rt.jar) and com.ctc.wstx.util.SymbolTable (from wstx-asl-3.2.7.jar). After removing wstx-asl lib from my classpath we made redeployment via tomcat manager with no errors.

How to configure web application in JProfiler?

I want to configure web application to JProfiler 7.1.2. Below are details which I carried out while configuring the session.
Web Server: Tomcat 5.0
Operating System: Windows XP
We have selected session type as "Web Start".
In Web Start settings section, How to select URL of JNLP file?
(we could not find out JNLP file).
Also we have selected Java VM as a "Oracle JRE 1.6.0_22".
We have configured Class Path.
After clicking OK after some time it shows application error as "Unable to launch application".
It shows error details as follows
CouldNotLoadArgumentException[ Could not load file/URL specified: D:\jakarta-tomcat-5.0.19\conf]
at com.sun.javaws.Main.launchApp(Unknown Source)
at com.sun.javaws.Main.continueInSecureThread(Unknown Source)
at com.sun.javaws.Main$1.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)
One more question, How can I add my project classes? I can not see project class file in Memory Views --> Agreegation Level --> Classes
Please guide me.
Awaiting reply

"Java Web start" has nothing to do with web applications. To profile Tomcat, invoke
Session->Integration Wizards->New Server Integration
and follow the steps in the wizard.
