    There had been some issues in TC 5.0. Cewolf is tested under
    TC 3.x and 4.x.
    The next version will also run on TC 5 but the current seems
    not to.

    I found out whats the problem. This will be fixed in 0.10 as
    I need to change the taglib for this. I'm not sure if TC 5.0
    JSP compiler works correctly. I compared the generated JSPs
    and think I have to talk to the Apache guys, if this
    behaviour is really correct.
    0.10 will unfortunalty brek 0.9 compatibility and will not
    be relaesed befor September, 1.
    I'm sorry for that.
    Regards,
    Guido

    Hi,
    I have a problem running CEWolf on Tomcat 5.
    I am able to run the WAR file perfectly but the problem is
    when I try to compile the PageViewData.java file , it compiles
    fine but the jsp gives an error while running.... the error
    is "Classdef not found" and "Wrong class"
    I need to make my own Dataset file to produce the graph
    data and have racked my head over this problem for a week.
    Is there a compatibility problem or am I missing something?

    Shawn.

    Sorry but Tomcat 5.0 is not supported yet.
