JBoss4.2.0.GA
jBPM 3.2.0.GA
Hi,
I'm trying to use jBPM 3 in an existing application. I can deploy processes
definitions, but when I try to get the process list, I get an error message :
[CachedConnectionManager] Closing a connection for you
Investigating on this error I found that :
- The error occurs in "org.jbpm.persistence.db.DbPersistenceService" when
the "Connection getConnection(boolean resolveSession)" method is called
- The connection hasn't been closed because when the "Exception
closeConnection()" method is called, the variable mustConnectionBeClosed is set
to false
Looking for the reason why "mustConnectionBeClosed", here is the code executed :
In my class :
jbpmContext.getGraphSession().findLatestProcessDefinitions()
In DbPersistenceService :
public GraphSession getGraphSession() {
if (graphSession==null) {
Session session = getSession(); //-- 1
...
public Session getSession() {
if ( (session==null)
&& (getSessionFactory()!=null)
) {
Connection connection = getConnection(false); //-- 2
if (isCurrentSessionEnabled) {
...
} else if (connection!=null) {
log.debug("creating hibernate session with connection "+connection);
session = getSessionFactory().openSession(connection);
mustSessionBeClosed = true;
mustSessionBeFlushed = true;
mustConnectionBeClosed = false; //-- 4
...
public Connection getConnection(boolean resolveSession) {
if (connection==null) {
if (persistenceServiceFactory.getDataSource()!=null) {
try {
log.debug("fetching jdbc connection from datasource");
connection =
persistenceServiceFactory.getDataSource().getConnection();
mustConnectionBeClosed = true; //-- 3
...
"mustConnectionBeClosed" is first set to true (//-- 3) getting the connection,
then set to false (//-- 4) some lines further, after opening the session.
Is this normal ? How to avoid the error message ? Did I miss something in the
configuration ?
Regards
A. ROY
