I created a report in Jazz Reporting Service and could run it successfully. Then I exported the document template and document definition for Rational Publishing Engine (using Export > Export the report to Rational Publishing Engine), imported it in RPE Launcher and configured the data source user name, password and the output path.

When trying to generate the report, the report is not generated and the following error message is displayed in the console.

In the JRS log file (C:\IBM\CLM\server\logs\rs.log) I find the following error messages

Versions: Jazz 6.0M9, Rational Publishing Engine 1.2.1

Note: I could not import the report definition generated by JRS into RPE 1.3. However, when manually creating the RPE report using the JRE report both in RPE 1.2.1 and 1.3 I get the same problem.

Hunch: already in the Jazz server one component is authenticating against the other. This involves invoking several URLs one after the other. When assembling one of these URLs, a malformed URL is generated using "j_security_check" as the host name. The correct URL would be something like https://localhost:9444/jts/j_security_check.

Any idea any one?
