Problems with Database Tutorial
I'm using Cocoon 2.1-dev, IBM JDK 1.3, running on RedHat 7.2, and using Sybase 11.9.2. I can't add or update users in the DB. I can only delete them. I tried this with both Sybase and Hsqldb and the results are the same. While using Sybase I had to remove the esql:parameter begin and end tags in order to actually edit the entry, otherwise I get an sql error stating that SELECT name, department_id FROM employee WHERE id = ? is an error. The id is being passed as a ? so it causes an error. When using Hsqldb I made no changes to the code. Has anyone ever seen this before? Where do I look in the log files for debug info, such as tracking what is taking place behind the scenes? Are there debug parameters that I can pass to Cocoon and receive more debug info. I'm new to Cocoon, but from what I see so far I like it. I have been somewhat at a loss when reading through the docs and I certainly understand the comments on the list regarding documentation. My wish list: A debug feature that outlines each move Cocoon makes, so I can trace what my code is producing and more importantly where it fails. -- Robert J.
