=== Environment ==============================
- jBPM Version : JBPM 4.1
- Database : AS400/DB2
- JDK : 1.5.017
- Container :1.5.017
- Configuration : the basic jbpm configuration comes with installation.
=== Problem description =========================
JBPM4.1 doesn't come with a db script for AS400/DB2. We created the script ourselves. It works mostly fine, however, we have troubles when we trying load the the deployed the definition from database. Here is the code.
| ProcessDefinitionQuery processDefQuery = repositoryService.createProcessDefinitionQuery();
|
| ProcessDefinitionQuery eBusinessProcessQuery = processDefQuery.processDefinitionKey("eBusinessApplicationProcessFlow");
| ProcessDefinition processDef = eBusinessProcessQuery.uniqueResult();
|
|
>From research has been done so far, it seems that JBPM is trying to assess the length method of blob after resultset is closed.
The part is having trouble in particular is the JBPM4_LOB. Here is the table script created for it .
| create table INTBPMMGT.JBPM4_LOB (
| DBID_ bigint generated by default as identity (start with 1, increment by 1),
| DBVERSION_ integer not null,
| BLOB_VALUE_ blob,
| DEPLOYMENT_ bigint,
| NAME_ clob,
| primary key (DBID_)
| ) ;
|
Can anyone gives a hand?
=== Stacktrace ==============================
