I'm not considering EAR files right now, and I'm not sure I (personally) will.
The JetspeedDeploy tool can be used to infuse a WAR file before deployment and then you don't need the autodeployment feature of J2 itself anymore but just rely on the autodeployment features of your webserver. For EAR files you can use the same procedure on your WAR files before storing them in the EAR. Then simply deploy the EAR file as usual. Of course, if you still want to be able to use J2 for EAR deployment you/someone can write a DeployEnterpriseApplicationEventListener and plug it in as one of the deployment listeners of the DeploymentManager. That should be quite simple to do, certainly after my refactoring ;-) I've created a new CVS branch, deployment-refactoring, in which I've committed my changes as of now.
The current version is tested with deployment to Tomcat 5.0.28 and Tomcat 5.5.8 using JDK 1.4.2_04 for both. I've not added much comments in the code yet, nor committed with lots of messages as I wanted to get this into the branch ASAP. But, when (if) this branch is merged back into the HEAD branch I'll try to document it as much as possible. I'd like to invite all the developer team members as well as interested users to check this branch out and test it as much as possible. For sure it isn't complete/finished yet so I certainly expect issues to be reported :-) I did run the tests though and, except for two, all run without failure: - Most tests in TestSimpleDeployment I've commented out for now as I haven't had time to write new tests conforming the new deployment. - The TestSSOComponent failed on me when using HSQLDB with an SQLException (FK constraint violation), but not with Oracle9i. I haven't run the test with HSQLDB on the current CVS HEAD but I expect it to fail there too as this problem isn't related to the changes in the branch. Anyone going to test this branch should be aware of the following: - Decorator deployment isn't in place yet (I discovered tonight I forgot to write it). I already thought out how to implement it and I will try to provide a first version tomorrow. - Portlet Application undeployment (local or now) is not in place either, and isn't going to work the *old* way anyhow. This will have to be implemented within the PAM portlets and/or manager servlet like Tomcat has itself (offline unregistration directly through the database is also an option). - The decorator portlet application is now (locally) deployed under context jetspeed-layouts. This means that all the layout fragments in the psml documents now are changed. Like: jetspeed::VelocityTwoColumns -> jetspeed-layouts::VelocityTwoColumns Finally, you now can deploy Jetspeed under a different context! You have to configure this by hand after deployment (I'll add a build configuration for it later): - rename jetspeed.xml - rename context path="/jetspeed" and docbase="jetspeed" inside jetspeed.xml - rename jetspeed.war - rename $TOMCAT/webapps/jetspeed Thats all. Regards, Ate A reply I've given to questions of David Sean Taylor on the dev mailing list:

Register and start(PortletApplication) are two different functionalities now. The start method invokes the (Registry) register method if a PA hasn't been registered before or if its portlet.xml checksum has changed. Furthermore, it invokes the PortletFactory register method, indicating the web application has started and thereby signaling the portal can access/invoke the portlets from this PA. Maybe I should change the "start" and "stop" method names to "init" and "destroy". I have thought about that before but just forgot to do. I'm not stuck on method names though so if you prefer something else please be my guest. You can change it yourself. Which brings me to an important issue for the whole Team: don't think I see this as *my* branch! If you find bugs, see something clearly wrong or stupid, or need changes for whatever reason: please take action. I hope we can commit this branch very soon but I also know there is still work to do to bring back *lost* features. Although branches are very easy to create and certainly the best solution for creating and presenting an alternative solution, I *hate* merging when there are many conflicting changes. Getting this done ASAP helps reducing conflicting changes. So, please lets all try to decide ASAP - if this branch is going to be merged - what needs to be done before the merge Any help with that I'd appreciate very much. > * why don't we support the registerAtInit option in the deployTool anymore Because it is required now. This is the primary functionality, already introduced as optional feature by Randy, needed for the new deployment and Portlet container interaction. Only after a Portlet Application has signaled "start" to the PortletApplicationManager it becomes available to the Portal for usage. Without it, its "not available", so "start" at init really must be "true". I've (re)implemented a very simple decorator deployer now.
Undeployment is, like with PA deployment, not available yet. It works almost the same as the "old" version except it doesn't use the (InMemory)SimpleRegistry anymore. Redeployment is therefore a bit different. It now only undeploys an existing decorator with the same "id" and "decorates" property. If you redeploy a decorator with a different "decorates" value the previous won't be undeployed! I'll provide more information about the changes later but because I don't have time left for today or tomorrow
I want to give the most important fact already now: JBoss (3.2.7) support. Everything works fine under JBoss, except for isUserInRole(rolename). After a short investigation I can say that our current JAAS security layer will *not* work out of the box with JBoss (and probably neither on several other JAAS supporting application servers). I will come back on this later. Login etc does work correctly though. Here are the instructions for getting this branch working on JBoss 3.2.7 (I also tested 4.0.1 shortly and it seems to work but I can't give it a 100% yet): build jetspeed-2 for Tomcat (5 or 5.5) with: maven allClean allBuild quickStart copy the contents of $TOMCAT_HOME/webapps/jetspeed into $JBOSS/server/default/deploy/jetspeed.war. remove *all* commons-logging-<version>.jar and log4j-<version>.jar from both jetspeed.war/lib as well as from all the war files inside jetspeed.war/WEB-INF/deploy: (jpetstore.war, jsf-demo.war, demo.war, pam.war, perl.war, php.war, security.war and struts-demo.war) These jars will give classloader problems otherwise because JBoss provides them already through a shared classloader. copy the contents of $TOMCAT/shared/lib into $JBOSS/server/default/lib (presuming $TOMCAT/shared/lib was empty before building). check $JBOSS/server/default/deploy/jbossweb-tomcat50.sar/server.xml: - element DefaultContext attribute crossContext="true" (which is the default) change $JBOSS/server/default/deploy/jbossweb-tomcat50.sar/META-INF/jboss-service.xml: - <atttribute name="Java2ClassLoadingCompliance">false</attribute> - <attribute name="UseJBossWebLoader">false</attribute> change $JBOSS/server/default/deploy/jetspeed.war/WEB-INF/assembly/jetspeed-spring.xml: - comment out entry "ApplicationServerManager" from bean with id "PortalServices" - comment out bean with id "org.apache.jetspeed.tools.pamanager.servletcontainer.ApplicationServerManager" copy jetspeed-ds.xml (or an adapted version like jetspeed-mysql-ds.xml) from the jetspeed-2 src folder portal/src/resource into $JBOSS/server/default/deploy. copy your jdbc-driver (as configured in jetspeed-ds.xml) to $JBOSS/server/default/lib (note: if you use the example hsqldb.jar setup of Jetspeed-2, you don't need to do this as JBoss provides it already) add *the contents* of jboss-login-config.xml from the jetspeed-2 src folder portal/src/resource to $JBOSS/server/default/conf/login-config.xml Happy testing ;-) Its done. The branch is merged with CVS HEAD.
For JBoss support I have updated (and simplyfied) instructions: build jetspeed-2 for Tomcat (5 or 5.5) with: maven allClean allBuild quickStart copy the contents of $TOMCAT_HOME/webapps/jetspeed into $JBOSS/server/default/deploy/jetspeed.war. remove commons-logging-<version>.jar and log4j-<version>.jar from jetspeed.war/lib copy the contents of $TOMCAT/shared/lib into $JBOSS/server/default/lib (presuming $TOMCAT/shared/lib was empty before building). check $JBOSS/server/default/deploy/jbossweb-tomcat50.sar/server.xml: - element DefaultContext attribute crossContext="true" (which is the default) change $JBOSS/server/default/deploy/jbossweb-tomcat50.sar/META-INF/jboss-service.xml: - <atttribute name="Java2ClassLoadingCompliance">false</attribute> - <attribute name="UseJBossWebLoader">false</attribute> change $JBOSS/server/default/deploy/jetspeed.war/WEB-INF/assembly/jetspeed-spring.xml: - comment out entry "ApplicationServerManager" from bean with id "PortalServices" - comment out bean with id "org.apache.jetspeed.tools.pamanager.servletcontainer.ApplicationServerManager" - change constructor-arg index="4" value to "true" for bean with id "portletAppDeploymentListener" This will strip commons-logging and log4j jars from the war file on deployment as required on JBoss copy jetspeed-ds.xml (or an adapted version like jetspeed-mysql-ds.xml) from the jetspeed-2 src folder portal/src/resource into $JBOSS/server/default/deploy. copy your jdbc-driver (as configured in jetspeed-ds.xml) to $JBOSS/server/default/lib If you use using the example hdsqldb setup of Jetspeed-2: - remove $JBOSS/server/default/lib/hsqldb.jar - *move* the hsqldb<-version>.jar from $JBOSS/server/default/default/jetspeed.war/WEB-INF/lib into $JBOSS/server/default/lib add *the contents* of jboss-login-config.xml from the jetspeed-2 src folder portal/src/resource to $JBOSS/server/default/conf/login-config.xml |

Resolving all deployment classloader problems
When refactoring the deployment mechanism, will you consider auto deployment of PAs embedded in EAR files as well? If not, when will it be addressed?
