[jbpm-users] [JBoss jBPM] - Problem using JBPM4 with DB2

[shiyeling]

Hi all,
We plan to use jBPM4 in our new project. 

But we noticed that the GA release does not come with a database schema script for DB2, does it mean that DB2 is currently not supported?

When we try it with db2(let the hibernate create db schema automatically ), we got exception says that could not insert into JBPM4_LOB because of: DB2 SQL Error: SQLCODE=-302, SQLSTATE=22001, SQLERRMC=null, DRIVER=3.53.95. 

It happens when the program try to deploy the process definition. And my guess is hibernate is trying to insert null value to blob/clob column which is not supported by database. 

Has any one meet this problem before?

Any help will be appreciated.


jBPM4 : 4.0.0.GA
DB2: 9.5.4.2
hibernate: 3.3.1.GA
