where do you get this error?

It looks like some jars are not in your classpath.

I get the same error when running any ant compile task that are distributed with jasperreports-1.3.3/demo/samples

:S

u are missing a necessary .jar file that this class net.sf.jasperreports.ant.JRAntCompileTask is trying to pull, get a list of setup .jars for ant and make sure they are all in ur class path.

[GalinaM]

They are all there, I double- and triple-checked. This is the out-of-the-box jasperreports distribution package.

 

Only the report compile tasks fail, the ones that invoke the jrc taskdef. Is there a way to run them on a command-line without ANT?

 

Thank you for your reply!

yeah u can if u are just looking to compile it once and not on the fly, download a program called iReports its free and compile it in there, if u already have it u do not need any ant lines to compile it, ant is more for compiling it over again when the user accesses it and gives parameters and u need to recompile, but there is very little situations where u would need to recompile on every report.
