Hi,

Yes, your classpath seems to be wrong, just include all libraries located in lib/ of the distribution you have downloaded.
There are many ways to set the classpath, here are some of them:
- javac -cp {jars,...} ...
- change the CLASSPATH environment variable of your OS
...

Hi,

demos are located in the package you have downloaded (src/org/jfree/chart/demo)
If you want more demos I think advanced ones are delivered with the commercial support:

Hi,

I think you should take a look to demos packaged with the distribution of JFreeChart. You can also buy the Developper guide.

see http://www.jfree.org/jfreechart/index.html for more informations.

Hi,

Yes, for php it is the best free charting tool (free for non commercial use )

Hi, erm Dataset.java seems to be where it has to be, look: http://cvs.sourceforge.net/viewcvs.py/jfreechart/src/org/jfree/data/ So can you tell us what did you do to compile (what commands,...)? Tried to recompile using 0.9.2.0.jar For me, it doesn't really mean anything. I think you are trying to c...

Hi,

org.jfree.util.* comes from jcommon package. Ensure you that you have put it properly in your classpath and i think that all will be okay.
If you are trying to compile a 0.9.20, jcommon is a 0.9.5

Hi,

I don't know for when the release is planed, but you can use the CVS to download its sources and use ANT scripts to build the library archive.

Hi,

Is that the full stacktrace? Usualy it tells where the class cast exception has occured. I hoped it cames from your code...

PS: if you don't already know, you have a little demo about how to use JFreeChart in JFreeReport (it is located in jfreereport-ext-x.x.x package).

As david said:

Hi,

can you post the full stacktrace?
(because it doesn't tell me where is the error)

Your code seems to be okay but i don't know types of parameters of all functions. The stacktrace will tell you/us exaclty where the cast exception comes from.

@Ayodele:

You just have to put JFreeChart in your class path (precompiled jars or compiled sources/) and all will work.

hi,

JFreeChart jar(s) (or src/ "handy" compiled version) seems to not be in your classpath.
After set it right, all will be okay.

Hi,

You can't directly post an image. You can just put a link to an image located somewhere on a http.

Hi,

jfreechart-0.9.19.jar has to be in libs.
After, just do as in demos, That's easy =)
(go through the demo/ directory located in src/)
