[wilfredo doming]

im trying to generate a time series chart,but it gives me an exception noSUchMethodError,i dont know whats the problem,because i try to use xyline and it works fine,can anyone please help me...thanks a lot,im using jfree10.0.12 and jcommon 10.0.15

Which version of cewolf are you using? Try the one linked in my signature, and use the JFreeChart and JCommon versions that come with it.

hi,
thanks for the reply,i try your cewolf version but it gave me the same error,nosuchmethoderror,also i use the jfree jar that's in it.however i try a lower version of jfree(jfree 1.0.0 and jcommon 1.0.0) and it works fine,dont whats really the problem,hope you can help me..thanks

My cewolf distribution comes with JFreeChart 1.0.11 and JCommon 1.0.14, and it works fine. I'm guessing that you may somehow have ended up with more than one version of one of these libraries in your classpath, or with different versions in your build path and runtime path.

You didn't post the details of the error message, and which code is causing it, so it's hard to say what's going on.

hi,i dont know if its the right forum,but what im doing is trying to add series of to a timeseriescolection.my problem is that it only gets the last collection of values it gets from my query.my observation is that it finished first the query loop the goes to the loop for the graph?but i cant figure out,why it behaves that way....can anyone please help me,thank you very much,.

Please do not post unrelated questions into existing topics. Also, as far as I can tell, the question has nothing to do with Struts, so it would be much better suited to the Other Open Source projects forum.
