[Soaplab-users] first run works, second throws an exception

[Marcus E. <er...@in...>]

Hey everyone,

I have been developing webservices with soaplab 1.1 for a while now, but 
suddenly encountered a problem. After I started the Applab server and 
Tomcat I can execute a webservice that is supposed to return an 
"outfile" without any problems. However right afterwards when I try to 
execute the same webservice I get an error. If I then restart Tomcat I 
can execute the webservice once more without that error so there must be 
something left over from the execution that prevents a successful 2nd 
execution. The result to return is created in both cases, so the problem 
shows up only when its time to return the file to Taverna.

Here is the error message that Taverna (1.4) throws:
