Greetings from Sweden.
How can we call a Servlet on another machine from Dialog Manager in Reporting Server?
If we call the Servlet, how can we receive the answer set?

Background:
We have a custom fuselib routine working that is calling Tuxedo to get authorization information for the current user. Now, the volume returned is too much to receive in an alpha variable. It also relies on environment variables which is not very flexible.

We also have a standard servlet already that we consider calling instead of maintaining this fuselib code.

Best regards,
Mats

I have called a Java servlet this way.
-DEFAULT &V1=Testing;
-DEFAULT &V2=Java;
SQL EDA EX javafex P1='&V1.EVAL', P2='&V2.EVAL';
TABLE FILE SQLOUT
PRINT *
ON TABLE HOLD AS MYDATA
END
TABLE FILE MYDATA
PRINT *
END
where javafex is:
SET EXORDER=PGM/FEX
CALLJAVA jva.test.TEST &P1, &P2


Is this the sort of thing you are looking for?

The other way is, you can write a Wrapper Servlet which extends WFServlet as well as the Servelt which you want to call on, and do the required things in Java side itself... Calling on to WFServlet with reqd params will fetch you the resultset there itself...


Thanks,

Ramkumar.

Hi Alan and Ramkumar.
Thank you for hints.
Alan's suggestion is like i was thinking.
Do i understand correctly that the java.test.TEST program would just type the data and the SQL EDA EX would map it (using SQLOUT)?

I would like to avoid using any chargeable option though. I don't think we will buy an additional adapter for this.
I will discuss this with java people.
Regards, Magts
