NoClassDefFoundError when trying to use jacl [message #1064827]

Hi,

I want to use some tcl code in java. Google revealed me that "jacl" should do the job via its function "eval". So I downloaded it and added the jars (itcl.jar, ..., tjcsrc.jar) to the project's (a plugin project) build path. Now the tcl code is needed when a certain handler is triggered. But then, as soon as I try to initiate the tcl interpreter via "Interp jacl = new Interp();" I get a "NoClassDefFoundError".

But the weird thing is that when I create a new java project, add the very same jars to the buildpath and do the same thing, everything works fine...

Do you have any idea why it doesn't work?

Cheers,
Maximilian

Google and some trying out actually revealed the answer to me! Smile

I didn't expect that a normal Java project and a Plug-in project would have to be treated differently...

Adding the jars as a library didn't have any effect at all. Instead I had to import the jars into my project as a file system (right click on project --> Import --> File System). Then adding them to the classpath - not the folder they are in but rather every single one of them (plugin.xml --> Runtime --> in the Classpath part "Add"...) and also this mysterious point (New and only a single point ".").

Is there any better way to do this?! And why doesn't it work to simply add the library to the build path?...
