Seems like your model has some Groovy dependencies. If you upload a jar, all the referenced classes (dependencies) of that jar must to be available to Guvnor. <div>What I recommend to do is to create a plain POJO model without any external library dependency (if possible) <br clear="all">

Hi,<br>
<br>
I am trying to upload a POJO jar file into drools guvnor. But it is throwing<br>
me an error saying "unable to load file".<br>
This is the file that am trying to upload<br>
<br>
<a href="http://drools.46999.n3.nabble.com/file/n3669841/QcResult.jar" target="_blank">http://drools.46999.n3.nabble.com/file/n3669841/QcResult.jar</a> QcResult.jar<br>
<br>
I am running drools guvnor 5.3 on tomcat server. When i looked into the logs<br>
of tomcat, the following is the stacktrace..<br>
<br>
