Posting by Jeroen BorgersJAMon-2.0 WebSphere 5.1 jakarta-oro classloading problem
If you run JAMon-2.0 in WebSphere (5.1) and when starting the JAMonAdmin.jsp page, you get the error message:
Error 500: org.apache.oro.text.regex.Util: method split(Ljava/util/Collection;Lorg/apache/oro/text/regex/PatternMatcher;Lorg/apache/oro/text/regex/Pattern;Ljava/lang/String;)V not found
You probably have a jakarta-oro classloading problem. Oro classes are available from a websphere-internal jar.
Put jakarta-oro-2.0.8.jar "in front" in the classloader hierarchy: WebSphereConsole-> server -> Process Definitions -> JVM -> set classpath = path_including_jakarta-oro-2.0.8.jar
See http://www-128.ibm.com/developerworks/websphere/techjournal/0406_brown/0406_brown.html clarifies the issue. When I execute the class finder servlet with the org.apache.oro.text.regex.Util class, it reports that this class is loaded from websphere/lib/jyton.jar. Nice tool this servlet BTW.
However, the solution provided by the article does *not* work.
The solution can be found at http://www.nabble.com/Re:-OpenCms6.0.0-on-IBM-WebSphere-5.1-p1061848.html
Note: if your app uses jakarta-oro of a different version than 2.0.8, you may have another version conflict to deal with.
