Deployment in Weblogic exception log4j template not found and jersey servlet due to ApplicationPath no being set

doingit

Dear All,

I am trying to deploy jforum-2.6.2.war in Weblogic 12.2.1 but I bump into following exception. I have also attached a file with the full stack trace.

Many thanks in advance for any help.

Is the war being extracted to a directory? Or is the app run directly form the war file? If the latter, that may lead to various issues. If possible, try having the war file exploded to a real directory.

Hi udittmer,

I was actually deploying the war file. But I did as you recommended, thanks. I unzipped the war and deployed the container folder. There was following issue


Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.

I changed the driver to com.mysql.cj.jdbc.Driver in jforum-2.6.2/WEB-INF/config/database/mysql/mysql.properties

However I am facing following issue now after last deployment. See full stack trace attached. I don't know how to tackle this one, thanks.

As to the first issue, that's just a warning. It should work fine as is. But I'll address it for the next release.

As to the second issue, that seems to have nothing to do with JForum - which doesn't use JAX-RS or Jersey. Is that something you added to the web app? If so, it apparently needs whatever library javax.cache.configuration.Configuration is in.

doingit

I just downloaded the jforum-2.6.2.war, unzipped it and changed the driver to com.mysql.cj.jdbc.Driver in jforum-2.6.2/WEB-INF/config/database/mysql/mysql.properties.
I am just deploying jforum, no other application code was added.
I realized that there was no weblogic-application.xml so I added a simple one at the META-INF folder (see below).


<?xml version="1.0" encoding="ISO-8859-1"?>

<weblogic-application

        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

The deployment is still throwing an exception.

I see. I'm not familiar with Weblogic, but it seems the stack trace is rather unhelpful because now it doesn't even mention which class is missing. But since it mentions "Truncated. see log file for complete stacktrace" - is there any other log file where there might be more information?

doingit

Please find attached the stack trace. That's all I could find. I tried to increase the logging to debug level.

udittmer

A ClassNotFoundException without mention of what class can not be found is singularly unhelpful. Or maybe it's trying to load a class named "" for some reason. But it doesn't say what it's trying to do at that point -except that it's trying to load JForum-, so there isn't much to go by on.
