Hi,

We developed a plug-in on Eclipse 3.1. We use plug-in to call the
jasperreoprt class (We registered jasperreport class and all its jar files
as third party in plug-in). The jasperreport works fine in RAD (Rational
Application Developer) and RSA (Rational Software Application)
environment. When we run the plugin, we got the following exception:

Unhandled event loop exception
Reason:
net/sf/jasperreports/engine/fill/JRFillParameter

We check it in the .metadata/.log file. It says the above file could not
be found. We run the
Class.forName("net.sf.jasperreports.engine.fill.JRFillParameter ").getName()
and also check it in the Eclipse prospective, it is there. Does anyone
have any idea of this error? Thank you in advance for your input.

Thanks

John

Hi John,

i had a similar problem. I am using log4j as logging facility in my
rcp application. I tried to create a new plugin from existing jars. I
add the new log4j-plugin to my dependencies. Also a
ClassNotFoundException occured. The only way to correct this was to add
log4j.jar to my plugin. I think it has something to do with the class
loaders. Each plugin has a own class loader

Hope this helps

Kind regards

Reinhard

Hi, Reinhard

Thank you for your input! I try to put the log4j.jar file in my plugin,
it still gave me the same error message. I use the log4j-1.2.8.jar. Which
versionof log4j file you use? Thank you again for your answer......

John
Problem with log4j is for log4j classes
You have another problem and it is eclipse classloader problem
search my thread in eclipse.platform
http://dev.eclipse.org/newslists/news.eclipse.platform/msg44 996.html.
I have solution with my classloaders, but correct is change in eclipse
classloader (ContextFinder)

Hi John,

i am using log4j version 1.2.8. You have to add the library also in
your plugin.xml file under Runtime->Classpath.

Snap, I believe the problem you described is what I encounter now. I never
use ClassLoader and ContextFinder before. Could you give me a simple
example to show me how the ClassLoader and ContextFinder associate with
the jasperreport on Eclipse? Thank you again for your help.
