Subject Incorrect output using WDSC for iseries
Date Sun, 27 Feb 2005 16:31:48 GMT
I have created a simple WebApp using the wizards in WDSC. Input form sends
select criteria to jsp which pulls data from iSeries table and displays output.
This works great if I run it in a Websphere test server running on the client
workstation. It does not work correctly if running on a Tomcat test server
running on the client or if deployed to a Tomcat server running on the iSeries. 

It returns the correct number of records in the output.jsp but they are all
repeats of the first record. There are no error messages and since it returns
some 'real' data, the connection must be working.

I first tried this using Tomcat 4.1.3 then upgraded to 5.5.7 with the same
results. 

Attached is wizard generated output.jsp code:
