--------------------------------------------------------------
Hi,
I am developing a web application which I will invoke a jbpm workflow. I am following a *spring-jbpm* integeration pattern to create a *kbase,ksession* etc.My question is how we have to use the *ksession*? Means for each request I have to create a seperate session(every process instance has unique session id ) or multiple process instances sharing the same *ksession.*
Currently I am following a spring approach in which one session id shared between multiple process instances. How to change this behaviour to make it one session per process instance.Is there any way to do this in spring. I tried bean scope"prototype" which will not workout. and jbpm session tag not having the attribute scope.
My XML is:
<jbpm:kbase id="kbase">
<jbpm:resources>
<jbpm:resource type="BPMN2" source="classpath:Hello.bpmn" />
</jbpm:resources>
</jbpm:kbase>
<jbpm:ksession id="ksession" type="stateful" kbase="kbase">
<jbpm:configuration>
<jbpm:jpa-persistence>
<jbpm:entity-manager-factory ref="entityManagerFactory"/>
<jbpm:transaction-manager ref="transactionManager"/>
</jbpm:jpa-persistence>
</jbpm:configuration>
</jbpm:ksession>
<bean id="ds" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver"></property>
<property name="url" value="jdbc:mysql://localhost:3306/jbpmworkflow?autoReconnect=true"/>
<property name="username" value="root"/>
<property name="password" value="root"/>
</bean>
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
p:dataSource-ref="ds">
<property name="persistenceXmlLocation" value="classpath:META-INF/persistence.xml" />
<property name="persistenceUnitName" value="org.jbpm.persistence.jpa" />
<property name="jpaVendorAdapter">
<bean class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
<property name="database" value="MYSQL"/>
<property name="showSql" value="true"/>
<property name="databasePlatform" value="org.hibernate.dialect.MySQL5Dialect" />
</bean>
</property>
</bean>
<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager" p:entityManagerFactory-ref="entityManagerFactory">
<property name="dataSource" ref="ds"/>
</bean>
Waiting eagerly for your replies.

[JBoss Transactions Development] - Narayana Release Process
by Paul Robinson
Paul Robinson [https://community.jboss.org/people/paul.robinson] modified the document:
"Narayana Release Process"
To view the document, visit: https://community.jboss.org/docs/DOC-17433
--------------------------------------------------------------
This page provides a list of instructions that must be done *in order* when doing a release of Narayana.
h2. Check JIRA
1. Check all issues resolved.
2. Create next point release version if not exists - this is so you can push issues in step 3 below.
3. Unresolved issues should be resolved or pushed.
h2. Check Hudson
Ensure no test failures in the group of hudson tests, for the branch you intend to release.
h2. Raise AS7 component upgrade request in Jira
Prepare for a PR to update AS7.
1. https://issues.jboss.org/browse/AS7 https://issues.jboss.org/browse/AS7
2. create a new 'component update' issue.1. Ensure the module is set to 'transactions'
2. select an appropriate 'fix for'.
3. Assign it to yourself.
h2. Do Release
h3. Git Branches (4.17 and 5 only)
Must be done first as the build-release-packages.xml relies on the tag being available
cd $NARAYAN_SRC/scripts
pre-release.sh <next version, e.g: 5.0.0.M3>
h3. Create the AS7 pull request branch and roll the jbosstm/jboss-as branch to next SNAPSHOT (UN-TESTED COMMANDS!!)
BRANCH=4_BRANCH
AS_BRANCH=master
JIRA=AS7-5815
CURRENT=4.17.2.Final
NEXT=4.17.3.Final
git clone git@github.com:jbosstm/jboss-as.git
cd jboss-asgit checkout $BRANCH
git remote add upstream git://github.com/jbossas/jboss-as.git
git pull --rebase --ff-only upstream $AS_BRANCH
sed -i "s/$CURRENT-SNAPSHOT/$CURRENT/g" pom.xml
git commit -am "Updated to $CURRENT"
# should use git merge-base $BRANCH upstream/master
git rebase -i HEAD~10
git checkout -b "${JIRA}_Upgrading_JBossTS_to_${CURRENT}"
git checkout $BRANCH
sed -i "s/$CURRENT/$NEXT-SNAPSHOT/g" pom.xml
git commit -am "Updated to $NEXT-SNAPSHOT"
git push origin ${JIRA}_Upgrading_JBossTS_to_${CURRENT}
git push origin $BRANCH
h2. Build and release
CURRENT=<Point version to release>

2. Forum
3. Blog: project in (jbtm, blacktie) AND fixversion = "5.0.0.M2" AND priority >= major AND issuetype not in (Bug, task) AND resolution not in ("Duplicate Issue", Rejected, "Won't Fix", "Out of Date", "Cannot Reproduce Bug")
