Hi. I have been using JENNIFER 4.5.5.
I have been using web-sphere and a part linked with JENNIFER without having any problem. As you might see from the attached file, however, I could not see the values but notice a message like below.
java.lang.RuntimeException: java.sql.SQLException: java exception : ’: java.lang.NullPointerException
When rebooting the JENNIFER, I do not see any errors. I was wondering what could I do to avoid seeing the same message again? Thanks.

Derby looks like having a problem. There could be many reasons, but the biggest problem is that you might see the error when the amount of data is huge. When you see the same error, I suggest you to use commercial or much stable DB including Orcle, db2, or mysql, instead of using derby.
