<p class="MsoNormal">The application works fine in Eclipse.<br>
<br>
In Eclipse, I created a jar file x.jar from the .class and a few .drl files, and copied x.jar to /tmp/x/<br>
<br>
Now, in /tmp/x<br>
CP="droos/*:drools/lib/*"<br>
java -cp "$CP" -jar dpvt.jar par...<br>
This fails on the first attempt to access any class from a drools jar file.<br>
<br>
In /tmp/x, I unpack x.jar and call<br>
CP="droos/*:drools/lib/*:."<br>
java -cp "$CP" rss.aws.init.Main par...<br>
AND THIS WORKS!<br>
<br>
So, what is different when starting a Java program with java -jar as opposed<br>
to java x.y.Main? <br>
<br>
The stack dump is not very informative:<br>

... 5 more<br>
<br>
Any ideas?<br>
