Executing Job or transformation via URL on Pentaho BI Server CE via Tomcat

Hello,

is there a possibility to execute a Kettle Job and/or transformation via an URL on the TomCat installation of Pentaho BI Server CE (5.01) ?

Something like "http://localhost:8080/pentaho/execute?myTransformation.ktr" ?

Thx and best regards in advance,

Andrej
