--------------------------------------------------------------
Hello, I recently upgraded JBossTS from 4.6.1 GA to 4.11 Final. I see that bug JBTM-532 that I opened against 4.5 and 4.6 should have been fixed in 4.8.0. However, I have a doubt on the current implementation of com.arjuna.ats.internal.jdbc.ConnectionImple.close().
I mean, if _theModifier is null, a comment says: "no indication about connections, so assume close immediately". However in this case only _theConnection is closed and set to null, while _recoveryConnection.closeCloseCurrentConnection() is not called. I think this may lead to connection leaks.
What I would expect is that if _theModifier is null, a log entry were added but nothing else were done; in particular I would expect not to return and let the following "if (!delayClose)" (towards the end of the method) close the connections immediately (both _theConnection and _recoveryConnection).
Before diving in debugging our application while monitoring the DBMS, I would like to know what JBossTS developers think about this and if I should open a JIRA.
Thanks in advance,
Mauro.

"Parse Messages between Actions"

--------------------------------------------------------------
Hey Guys.
I am pretty new to JBossESB, so please be kind! :)
My basic question is, how do I parse messages through actions not using org.jboss.soa.esb.message.defaultEntry as the key?
So I tried using
<action class="org.jboss.soa.esb.smooks.SmooksAction" name="desadv2ObjShipment">
<property name="smooksConfig" value="META-INF/smooks-desadv-import.xml" />
<property name="resultType" value="JAVA" />
<property name="reportPath" value="/tmp/garuda/report-in.html" />
<property name="javaResultBeanId" value="objShipment" />
<property name="set-payload-location" value="get-order-response" />
</action>
<action class="org.jboss.soa.esb.smooks.SmooksAction" name="desadv2ObjShipment">
<property name="smooksConfig" value="META-INF/smooks-desadv-import.xml" />
<property name="resultType" value="JAVA" />
<property name="reportPath" value="/tmp/garuda/report-in.html" />
<property name="javaResultBeanId" value="objShipment" />
*<property name="set-payload-location" value="get-order-response" />*
</action>
My next actions is like this
<action class="org.jboss.soa.esb.actions.EJBProcessor" name="callPersist">
<property name="ejb3" value="true" />
<property name="jndi-name" value="garuda-core/ObjShipmentManagerBean/remote-de.eskalon.kn.garuda.api.ObjShipmentManager" />
<property name="initial-context-factory" value="org.jnp.interfaces.NamingContextFactory" />
<property name="provider-url" value="localhost:1099" />
<property name="method" value="persistObjShipment" />
<property name="ejb-params">
*<arg0 type="de.eskalon.kn.garuda.database.domain.ObjShipment">org.jboss.soa.esb.message.get-order-response</arg0>*
</property>
</action>
But that just doesn't work! Anyone knows what I am doing wrong?
Thanks for your help!
Best regards
Phillip Schulte

* On IRC - irc://irc.freenode.org/jboss-as7 or https://webchat.freenode.net/?channels=jboss-as7 (http://webchat.freenode.net/?channels=jboss-as7)
h4. 9. Make sure there is a JIRA somewhere for the enhancement/fix
http://jira.jboss.org http://jira.jboss.org
h4. 10. Create a simple topic branch to isolate that work (just a recommendation)
git checkout -b my_cool_feature
h6. Note: See tips section for how to use a nice git prompt for tracking what branch you are in!
h6. 11. Make the changes and commit one or more times (Don't forget to push)
git commit -m 'JBAS-XXXX Frunubucate the Fromungulator'
git commit -m 'JBAS-YYYY Tripple Performance of Fromungulation'
git push my_cool_feature
+Note that git push references the branch you are pushing and defaults to master, *not your working branch*.+
h4. 12. Rebase your branch against the latest master (applies your patches on top of master)
git fetch upstream
git rebase -i upstream/master
# if you have conflicts fix them and rerun rebase
git push my_cool_feature
The -i triggers an interactive update which also allows you to combine commits, alter commit messages etc. It's a good idea to make the commit log very nice for external consumption. Note that this alters history, which while great for making a clean patch, is unfriendly to anyone who has forked your branch. Therefore you want to make sure that you either work in a branch that you don't share, or if you do share it, tell them you are about to end the branch.
h4. 13. Get your changes merged into upstream
1. Make sure your repo is in sync with other unrelated changes in upstream before requesting your changes be merged into upstream by repeating step 12.
2. Email a pull request to mailto:jbossas-pull-requests@lists.jboss.org jbossas-pull-requests(a)lists.jboss.org (if I haven't subscribed the list, do it https://lists.jboss.org/mailman/listinfo/jbossas-pull-requests here) with a link to your repo, a description of the changes, and who reviewed (if any)
3. After review a maintainer will merge your patch, update/resolve issues by request, and reply when complete
4. Don't forget to switch back to master and pull the updates1. git checkout master
git pull upstream master
h4. *Appendix A. Adding a new external dependency*
1. Edit pom.xml and add a property of the form "version.groupId.artifactId" which contains the Maven version of the dependency. Add your dependency to the <dependencyManagement> section, and use the property for the version. If your new dependency has any transitive dependencies, be sure to <exclude> them (or if possible, update the project so that all its dependencies are of *provided* scope).
2. Add your dependency to any AS modules that require it, but only with group/artifact.
3. Edit build/pom.xml and add your dependency with only group/artifact.
4. Create a directory in build/src/modules corresponding to the *module's* name (which will differ from the Maven group/artifact name; look at other modules to get a feel for the naming scheme), with a version of "main", like this: "build/src/modules/org/jboss/foo/main".
5. Create a module.xml file inside the "main" directory. Use a module.xml from another similar module as a template.
6. Edit build/build.xml and add a <module-def> element. The name listed in the <module-def> element corresponds to the *module* name. The group/artifact listed in the nested maven-resource element(s) refer to the *Maven* group/artifact name.
7. *Important:* Make sure you did not introduce any transitive dependencies by using "mvn dependency:tree". If you did, be sure to add <exclusion>s for each of them to your dependency as described above.
Please be sure to preserve the alphabetical ordering of all POMs and the build.xml file.
h4. Appendix B. Adding a new AS submodule
1. Create the directory corresponding to the submodule and add it to the root pom.xml file. The convention is to leave off the "jboss-as-" portion, so "jboss-as-remoting" becomes "remoting".
2. Create a POM for your submodule (use another submodule as a template). Make sure all dependencies you specify do *not* include a version. The group ID should be "org.jboss.as", and the artifact ID should begin with "jboss-as-" and there should be a proper <name> for the new module.
3. Add the new submodule to the top section of the <dependencyManagement> of the top-level pom.xml. The version should be set to "${project.version}". This section is sorted alphabetically by artifact name so please preserve that ordering.
4. Add your submodule dependency to any AS modules that require it, but only with group/artifact.
5. Edit build/pom.xml and add the new submodule with only group/artifact.
6. Create a directory in build/src/modules corresponding to the submodule, with a version of "main", like this: "build/src/modules/org/jboss/as/new-subsystem/main".
7. Create a module.xml file inside the "main" directory. Use a module.xml from another subsystem as a template.
8. Edit build/build.xml and add a <module-def> element for the subsystem. Use the module name and Maven coordinates from steps 6 and 2 respectively. Use another submodule as a template.
Please be sure to preserve the alphabetical ordering of all POMs and the build.xml file.
h4. Tips & Tricks!
h4. Creating a Git status prompt in your terminal
This makes it easy to not forget what branch you are working in and quickly tell if you have changes. The following will adjust the PS1 on unix (or cygwin on Windows). Note that it assumes a compiled version of git, which is also the case for the OSX packages. If you are using the bundled rpm version, change the completion path to "/etc/bash.completion.d/git"
GIT_COMPLETION_PATH="/usr/local/git/contrib/completion/git-completion.bash"
if [ -f "$GIT_COMPLETION_PATH" ]; then
GIT_PS1_SHOWDIRTYSTATE=true
. "$GIT_COMPLETION_PATH"
ADD_PS1='$(__git_ps1)'
fi
if [[ ${EUID} == 0 ]] ; then
PS1="\[\033[01;31m\]\h\[\033[01;34m\] \w\[\033[33m\]$ADD_PS1\[\033[34m\] \$\[\033[00m\] "
else
PS1="\[\033[01;32m\]\u@\h\[\033[01;34m\] \w\[\033[33m\]$ADD_PS1\[\033[34m\] \$\[\033[00m\] "
fi

Hi,
I use drools 5.1 and I would like to use gwt-console with mina task server, but I miss in the gwt-console the group assignment of tasks.
I've seen the source and I found in DroolsFlowTaskManagement.java the getUnassignedTasks function, what is fail. The value of the second parameter (participationType) is every "null" and this function call the "client.getTasksAssignedAsPotentialOwner" function in everytime. But, client.getTasksAssignedAsPotentialOwnerWithGroup and client.getTasksAssignedAsPotentialOwnerByGroup functions are never used. So, the group assignment is miss.
I've downloaded from hudson the source code of drools 5.2 version, but that source code is same.
I need to use this function of the gwt-console and I would like to know write the missing code or can somebody send me a solution.
Can somebody help me?
Thanks,
Csaba
