Trouble accessing java objects [message #21113]

Hi!

I've got some trouble accessing a java object within evl/eol.
The given example works fine:

var frame := new Native('javax.swing.JFrame');

But when I try to call my own object like

var clazz := new Native('workflow.validation.TestClass');

I'm getting the following error message:

"Type 'workflow.validation.TestClass' not found"

Any suggestions?

Greetings

Hi Arian,

You need to make Epsilon aware of your class. If it's not already in the
classpath, you can do this by providing an extension to the
org.eclipse.epsilon.common.dt.tool extension point. See
https://dev.eclipse.org/svnroot/modeling/org.eclipse.gmt.eps ilon/trunk/plugins/org.eclipse.epsilon.eol.dt.tools/plugin.x ml
for some examples.

Cheers,
Dimitris

Hi All

I tried to use some native Java class in EOL but I haven't success. Even I used Dimitrios's and Louis's document named "Epsilon Tools" even information from this thread - if I start attached "nt.eol" script from inside of Eclipse, I will get error is "Type 'nativetest.NativeTest' not found". But if I start it from "generated" Eclipse application, script work ok.

Probably I must be something overlooking ... can someone take a look to attached sources and help me?

Thanks in advance

Hi Ivosh,

This is the expected behaviour as Epsilon couldn't possibly know
anything about your plugin until it is activated (i.e. in a runtime
workbench).

Cheers,

thank for your quick (and easy :-) ) answer. Surely I need more studying
and practice on Eclipse plug-ins.
