[ptt-users] Re: NPE in ScriptRunner.methodFromCall(ScriptRunner.java:239)

[Lars Huttar]

Well, that particular error was apparently caused by the fact that I was 
missing a langtype attribute on my <run> element:
                                                          <run 
module="ethnunit" name="test1" testclass="HTTPExample" method="runtest" />

After supplying langtype="jython", that particular NPE goes away.
Hopefully that could be fixed to tell the user they're missing a 
langtype attribute, if it is indeed required.

Now I get a different set of errors:
