Re: exposing exceptions that caused a rollback
Hi Djencks/Dblevins,
As we had discussed earlier about this issue and the possible patch. It
seems we cannot use javax.transaction.
TransactionRolledbackException.initCause(e) instead there is another class
with in openEJB
org.apache.openejb.core.transaction.TransactionRolledbackException which can
be utilized. So can we go ahead
and use this exception class. Are there any reasons why we had not used this
class earlier?
For your reference
have a look at line no 146 in the class
https://svn.apache.org/repos/asf/openejb/tags/openejb-3.0.3/container/openejb-core/src/main/java/org/apache/openejb/core/transaction/TransactionPolicy.java
Once I use this class I see better logging however it stills seems
incomplete. What can we do to get more logging in this case?

For a long time we've known of this problem where an exception thrown by
a transaction synchronization that causes a transaction to be marked for
rollback only is lost. When the user or openejb tries to commit the
transaction the transaction manager throws a RollbackException which
currently doesn't have any information about the original exception.
People have complained about this for a long time now we're trying
to fix it.
There are two parts AFAICT. I think in openejb we just need to take the
TransactionRolledBackException we are currently throwing and call initCause
with the RollbackException from the tm. In TransactionPolicy this would be
something like
} catch (RollbackException e) {
txLogger.info(The transaction has been rolled back rather
than commited: + e.getMessage());
// TODO can't set initCause on a
TransactionRolledbackException, update the convertException and related code
to handle something else
Throwable txe = new
javax.transaction.TransactionRolledbackException(Transaction was rolled
back, presumably because setRollbackOnly was called during a
synchronization: +e.getMessage());
--throw new ApplicationException(txe);
++throw new ApplicationException(txe.initCause(e);
In the transaction implementation we need to keep track of the exception
that caused us to mark rollback only and then use it as the cause of the
RollbackException, e.g.
private Exception markRollbackCause;
...
RollbackException rollbackException = new RollbackException(Unable to
commit: transaction marked for rollback);
if (markRollbackCause != null) {
rollbackException.initCause(markRollbackCause);
}
throw rollbackException;
...
private void markRollbackCause(Exception e) {
if (markRollbackCause == null) {
markRollbackCause = e;
}
}

Hi Manu, Apologies for delay in reply. Yes I have started looking on to the spec and will come up with test cases soon.

What do you think? To download the Eclipse plugin for OpenEJB, do the following: 1. svn co http://svn.apache.org/repos/asf/openejb/trunk/sandboxopenejb-sandbox 2. cd openejb-sandbox/openejb-eclipse-plugin 3/ mvn clean install ...install the plugin - assembly\target\openejb-eclipse-plugin-1.0.0-SNAPSHOT-deployable.zip - as you do with other plugins (I copy it over to a directory with .eclipseextension and link it with *.link file). Run Eclipse and you should notice OpenEJB menu. I've just committed the latest changes of Jonathan's. They built fine and worked well. Jacek -- Jacek Laskowski http://www.JacekLaskowski.pl

where to find the latest Eclipse plugin for OpenEJB
Hi, I am looking to setup development environment for OpenEJB. These are the steps I followed 1) Checkout the code. 2) Ran the build. 3) Ran the command *C:\OpenEjbmvn -Peclipse eclipse:eclipse *4) Finally I followed the steps as mentioned in * https://issues.apache.org/jira/browse/OPENEJB-674. *5) For Step4 I downloaded *xxx_final.zip. * Now I am a stuck at *B. Adding a new installed runtime * 4. Click next and specify the location of the installation directory of OpenEJB During the 4th step I get the error *Missing classpath entry C:\openejb3.0b2\openejb- 3.0-beta-2\lib\openejb-core-3.0.0-SNAPSHOT.jar * There are no snapshots jar present in *openejb_home/lib*. what it suggests is plugin is referring to some old jars. Is that the reason? Is there any way we can modify the the classpath entry to point to correct jar. Is there an alternate plugin available? PS: I am using WindowsXp. Thanks Ashish

Re: allowHosts in OpenEjb3.0
Hi Kevan, Thanks for your suggestion. Can you suggest me how can I use openejb start -Dadmin.only_from=127.0.0.1 in geronimo?

Ashish, OpenEJB 3.0 supports an 'only_from' configuration option. Running openejb standalone, you should be able to accomplish what you want. E.g.: openejb start -Dadmin.only_from=127.0.0.1 (note: I've never used this...) As I've noted on Geronimo dev list, we may be able to get this configured with existing codebase in Geronimo. If this feature is important to users, we should probably get 'allowedHosts' support back into Geronimo... Either way, it's a discussion for the geronimo list... --kevan
