--------------------------------------------------------------
Hello everynone. My first post. I think I read every post about the jBpmContext and nothing gave me the solution...
I'm using jBPM 3 with SEAM. I launch an asynchronous event which launches a ProcessInstance.
I am using another asynchronous event to cancel the previously launched ProcessInstance.
@Observer("builderObserver")
public void startProcessForBuilder(final PackageConfiguration packageConfiguration, final Package pack) {
try {
final JbpmConfiguration jbpmConfig = JbpmConfiguration.getInstance();
final JbpmContext jbpmContext = jbpmConfig.createJbpmContext();
final GraphSession graphJbpm = jbpmContext.getGraphSession();
final ProcessDefinition processDef = graphJbpm.findLatestProcessDefinition("builder");
final ProcessInstance processInstance = processDef.createProcessInstance();
processInstance.getContextInstance().setVariable("packageConfigurationId", packageConfiguration.getId());
jbpmContext.save(processInstance);
pack.setJbpmProcessId(processInstance.getId());
processInstance.getContextInstance().setVariable("packLauncher", pack);
....
@Observer("cancelBuilderObserver")
public void cancelProcessForBuilder(final Package pack) {
try {
final JbpmConfiguration jbpmConfig = JbpmConfiguration.getInstance();
final JbpmContext jbpmContext = jbpmConfig.getCurrentJbpmContext();
final GraphSession graphJbpm = jbpmContext.getGraphSession();
final ProcessDefinition processDef = graphJbpm.findLatestProcessDefinition("builder");
final ProcessInstance processInstance = graphJbpm.getProcessInstance(processDef.getId());
...
But when I do jbpmConfig.getCurrentJbpmContext(); the value is null. It is probably due to different transactions.
I just want to be able to end a processInstance using its id.
Could you please help me?
Thanks.

[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-as
git 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 "Upgrade Narayana to $CURRENT"
# should use git merge-base $BRANCH upstream/master
# You will need to resolve som merge conflicts. Most likely around version numbers.
git rebase -i HEAD~10
git checkout -b "${JIRA}_Upgrading_Narayana_to_${CURRENT}"
git checkout $BRANCH
sed -i "s/$CURRENT/$NEXT-SNAPSHOT/g" pom.xml
git commit -am "Upgrade Narayana to $NEXT-SNAPSHOT"
git push origin "${JIRA}_Upgrading_Narayana_to_${CURRENT}"
git push origin $BRANCH
h2. Build and release
CURRENT=<Version to release. e.g 5.0.0.M2>
mkdir -p ~/narayana/filemgmt.jboss.org/
On Linux:
sshfs jbosstm(a)filemgmt.jboss.org (mailto:jbosstm@filemgmt.jboss.org): ~/narayana/filemgmt.jboss.org/
On MacOS:

git clone git(a)github.com (mailto:git@github.com):jbosstm/narayana.git
cd narayana
git checkout $CURRENT
On Linux:
ant -f build-release-pkgs.xml dist downloads docs magnolia -Drsync=false
On MacOS:
ant -f build-release-pkgs.xml dist downloads docs magnolia

h2. Release the artifact through Nexus
1. https://repository.jboss.org/nexus/index.html#welcome https://repository.jboss.org/nexus/index.html#welcome
2. login
3. "Staging Repositories"
4. Click tickbox for your repo
5. Click "Close"
6. Don't worry about a description, just click "Close"
7. Click tickbox after it is closed
8. Click "Release"
9. Again a description doesn't matter
h2. Push Upstream
Check that the pull request will work. *If it doesn't and it requires Narayana changes you *have* to rev the version number - DON'T attempt to re-release with the same version number:*
JIRA=AS7-5815
CURRENT=4.17.2.Final
git clone mailto:git@github.com git@github.com:jbosstm/jboss-as.git

./build.sh clean install
1. Raise the pull request using our branch
2. Once merged, resolve the AS7 Jira issue.
h2. JIRA Release
1. Close all issues for the release
2. Mark as released (Need admin permissions)
h2. Update Website
Update the Narayana community site:

* Edit the first line to change '<sv:node sv:name="5.0.0.M2"' to replace the '.' with '_'. Make it look like htis: '<sv:node sv:name="5_0_0_M2"'
* Save the files, ready for upload.
* Login to Magnolia* https://www.jboss.org/author/.magnolia/pages/adminCentral.html https://www.jboss.org/author/.magnolia/pages/adminCentral.html

h2. Promote
NOTE: It is worth waiting for the merge of the pull request before advertising, or at least wait for the merge build notification first ;)
Promote the release through the following channels:
1. Email jbossts-announce(a)lists.jboss.org (mailto:jbossts-announce@lists.jboss.org)
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")
