Query: Running a Sample Web application in Tomcat
Hi,
I am trying to execute a Sample web application (calculator-webapp) from the
tuscany-sca-0.91-incubating Release. I am using "Tomcat V 6.0" as a
application server. The original sample which is there in the release will
get executed fine and i can able to see the results.
But In the same sample, i modified few things and added one more service
and built the WAR file. If i try to run this, i get the following error.
I could able to test the new service by building the sample using MVN (
using JUnit assertEquals, that is comparing the expected result with the
result returned by the service), it works fine. But when i try to run the
same using Eclipse with Tomcat v6.0.
*type* Exception report

*description* *The server encountered an internal error () that prevented it

Please let me know if anyone had faced the similar problem.

Hi Ant,

"squareRootService" and "SquareRootServiceImpl" impliments the same.
