[jira] Created: (TAPESTRY-2026) classloader issue with org.slf4j.Logger

classloader issue with org.slf4j.Logger
---------------------------------------

                 Key: TAPESTRY-2026
                 URL: https://issues.apache.org/jira/browse/TAPESTRY-2026
             Project: Tapestry
          Issue Type: Bug
    Affects Versions: 5.0.7, 5.0.6
         Environment: eclipse 3.3 run-jetty-run plugin jetty 6.1.6 jdk1.6.0_03 windows XP
            Reporter: stanislav kutil


There seem to be a problem with loading org.slf4j.Logger class when using either patched jetty launcher (to support jetty6) or run-jetty-run eclipse plugin. It does not happen with official jetty launcher & jetty5 (although the official jetty launcher doesn't support java6). Also it doesn't seem to be jetty6 specific issue because wen running jetty with mvn jetty:run the exception is NOT thrown.


An unexpected application exception has occurred.

    * java.lang.RuntimeException
      java.lang.ClassNotFoundException: caught an exception while obtaining a class file for org.example.myapp.pages.Start
    * java.lang.ClassNotFoundException
      caught an exception while obtaining a class file for org.example.myapp.pages.Start

      exception

I believe this issue was discussed on the tapestry-users mailing list. The fix was to add this JVM argument:

-Dorg.mortbay.jetty.webapp.parentLoaderPriority=true

It works for me.

[jira] Commented: (TAPESTRY-2026) classloader issue with org.slf4j.Logger

Posted by "stanislav kutil (JIRA)" <de...@tapestry.apache.org>.
    [ https://issues.apache.org/jira/browse/TAPESTRY-2026?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12561604#action_12561604 ] 

stanislav kutil commented on TAPESTRY-2026:
-------------------------------------------

I belive they are on the classpath at runtime... jetty won't start without them. Also noticed that when I add them to WEB-INF/lib as well the classloader complains about already having loaded the classes (probably a conflict with another version of the class?)

> There seem to be a problem with loading org.slf4j.Logger class when using either patched jetty launcher (to support jetty6) or run-jetty-run eclipse plugin. It does not happen with official jetty launcher & jetty5 (although the official jetty launcher doesn't support java6). Also it doesn't seem to be jetty6 specific issue because wen running jetty with mvn jetty:run the exception is NOT thrown.

[jira] Closed: (TAPESTRY-2026) classloader issue with org.slf4j.Logger

Posted by "Howard M. Lewis Ship (JIRA)" <de...@tapestry.apache.org>.

    Resolution: Invalid
      Assignee: Howard M. Lewis Ship

This would appear to be a problem with the Eclipse plugin(s) you are mentioning.  Have you asked them about it?  Are you sure that the SLF4J JARs (plural!) are on the classpath at execution time?
