Problem reproducing EOL Tool Simmetrics Example [message #519148]

Hi,

I'm stuck trying to reproduce the Simmetrics Tool example. I'm exporting the tool as a plugin, place in the dropins folder and can see it in the Epsilon perspective in the tools tab. No problem there. However, when trying to use the similarity function, I keep getting a class not found exception: java.lang.ClassNotFoundException: uk.ac.shef.wit.simmetrics.similaritymetrics.JaroWinkler

I'm really no expert creating Eclipse plugins. So I have been putting the library in the plugin's build path and added it to the bundle-class path ... with little success.

What am I overlooking? How should the Manifest for the example look like?

Thanks a lot for your help!
Anne

Hi Anne,

The Simmetrics example is out of date (had to remove simmetrics.jar due
to licensing issues). For an up-to-date example of calling Java from
Epsilon please have a look at
http://eclipse.org/gmt/epsilon/doc/articles/call-java-from-e psilon/
Please let me know if you specifically need the Simmetrics example and
I'll try to restore it under epsilonlabs.sf.net .

Cheers,
Dimitris

Hi Dimitris,

thank you for the quick reply and the article. I had checked the article before and don't think that this is where the problem lies. The tool works fine for functions not accessing the simmetrics library. So I guess my problem is somehow with exporting the simmetrics jar...

Thanks again,
Anne

Hi Anne,

To make simmetrics.jar visible to your tool, you need to create a plugin
from it using the New->Plug-in from Existing JAR Archives wizard and
then add the created simmetrics plugin to the dependencies of the plugin
where you define the tool.

Cheers,
Dimitris
