Hi,

check, whether you have the correct jcommon version installed for each webapp and that you did not put the jcommon into $JRE/lib/ext or Tomcats $CATALINA_HOME/common/lib directory. Each web application should have its own, distinct set of libraries (especially since JCommon/JFreeChart is usually not backward compatible (for now), so strange errors might arise from that).

Have mo' fun,

I had the similar erro and problem too,

I have posted a thread in

I have checked the JCommon I am using it is the same, it is also JCommon 1.0.

I got the error when I am trying to refer to the CategoryAxis class, how can I solve this problem ?

[kianfatt1982]

I already have my snippets of codes written in here :-

http://www.jfree.org/phpBB2/viewtopic.php?p=44400#44400

the code compiled fine in J2SDK 1.4 and run fine in JRE 1.4, but when I move the class files to the Server with the JRE 1.3 Environment the error occurs

I have been recomended some solutions the JFreeChart Forum, and my attempts to solve this problems are as posted in,

So lets us go there and disscuss this together.
