Hi,

 

You are trying to compile a report in the applet.

This is not a very good idea.

 

Compilation needs access to the disk and requires

a lot of libraries in the classpath that you have to

transfer over the network in a Web environment.

This includes tools.jar which is not a small JAR file.

 

Report designs should be compiled only once, at

design time, just like you compile your application

source files. At runtime, you should only use

the .jasper files to fill them with data.

 

Using applets is a good idea only when you want

to display reports generated on the server side, and

I'll provide a sample to explain all that in the next

release.

 

Thank you,

Teodor

Hi,

 

I'll provide a complete Web application sample

with HTML exporter and applets

It will be available with the 0.4.1 in one or two days.

 

Thank you,

Teodor
