[Design of JBoss Deployment Framework] - Russian doll packaging in arbitrary directories - JBAS-5900

by adrian＠jboss.org

https://jira.jboss.org/jira/browse/JBAS-5900 This raises the issue of a change in behaviour in "Russian doll" packaging in JBoss5. The behaviour asserted is actually not tested in the AS testsuite, instead it is documentated to be otherwise, see "Deploy Applications Inside of An Application" here: http://docs.jboss.org/jbossas/upgrade4/html/ "If you want to make a subdeployment (for those archives that support simple Russian Doll packaging), place it in the root of the parent deployment." (My emphasis) Possible Solutions: 1) We could create a new but deprecated "DirectoryStructure" that adds this behaviour for backwards compatiblity purposes. i.e. instead of ignoring directories inside deployments that don't have a META-INF subfolder, we could scan them (recursively) for deployments. 2) We could add something to that treats directories like "lib" specially and scans them for jars, since this is becoming a standard within JavaEE. 3) Close the issue saying it was an "undocumented feature" View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4173370#4173370 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4173370

Sure you can, but I find this more convoluted than having a explicit create/delete queue methods. Besides, creating temp queues is done in many messaging patterns and I'd prefer to keep a method to do that as part of our core API without relying on management API.

[Design of JBoss Transaction Services] - Re: ClientUserTransaction and TxPropogation inefficiencies

by adrian＠jboss.org

"jhalliday" wrote : > The ClientUserTransaction is only a proxy to a real transaction on the server so JTS is irrelevant for normal clients | | Unfortunately not. If a normal (i.e. without ORB) client is using UT to communicate to a server and that server is switched from the JTA to the JTS, the client will break. Of course that may be a bug rather than a design issue. | | Then there is the question of what the behaviour should be when the client is using RMI/IIOP rather than JRMP for transactional calls to the server. Should it need the JBossTS libraries, or should it continue to use UT? What if it wants to switch to JBossTS? Using either the JTA API or the CORBA API for transaction demarcation. So you're saying the TPC obtained by UserTransactionSessionImpl is not usable by the client when JTS is installed on the server? | public Object begin(int timeout) | throws RemoteException, | NotSupportedException, | SystemException | { | TransactionManager tm = getTransactionManager(); | // Set timeout value | tm.setTransactionTimeout(timeout); | // Start tx, and get its TPC. | tm.begin(); | Object tpc = getTPCFactory().getTransactionPropagationContext(); // HERE !!!! | // Suspend thread association. | Transaction tx = tm.suspend(); | // Remember that a new tx is now active. | activeTx.put(tpc, tx); | // return the TPC | return tpc; | } | In that case, it is a bug. We probably need some new api to differentiate the two use cases of getTPC(). 1) When propogating calls to other servers 2) When retrieving a TPC usuable by a client to control UTs.
