RE: Java for Batch and Reporting

I looked at a product called CrystalClear, I tested it a year ago, and it
looked very nice...  Its www.inetsoftware.de It would allow me to place my
crystal report files, in the ifs and run it nativly..

Here is a small piece of code I wrote a while ago to test it..

The only feature, I'm waiting for, before I buy it is..  Specified order
grouping in a crosstab... They have it, in a standard report... But I use it
a lot in crosstabs...

Any of you have any experience of coding heavy-duty batch update/reporting
functions in Java on iSeries?

I'm particularly interested in the performance aspects and if anyone has any
exposure to the Crystal or other reporting software.
