[JBoss AOP] - Re: howSwap in JBoss Application Server
by flavia.rainone＠jboss.com
Hi!
To run JBoss AOP in hotswap mode, you need to pass the -hotSwap option to the jdk50 agent:
$ java -cp=<classpath as described above> -Djboss.aop.path=<path to jboss-aop.xml> \
| -javaagent:jboss-aop-jdk50.jar=-hotSwap com.blah.MyMainClass
To see more on this, refer to the Reference Manual, item 11.2.3 (HotSwap)
However, we don't advise the usage of this feature since we have some issues with the jvm that need to be solved.
Fortunately, hotswap is not the only way to interweave aspects into already loaded classes. You can do this using anyone of the weaving modes. You just need to follow the dynamicAOP example of our tutorial. Notice that this example should work on all modes, including loadtime weaving with hotswap enabled.

[JBoss jBPM] - Re: jBPM 3.2 using CMT
by MSchmidke
Ok,
binding JBoss' Hibernate Session Factory to JNDI via persistence.xml:
| <persistence-unit name="MyEJBPU" transaction-type="JTA">
| <jta-data-source>java:jdbc/myDS</jta-data-source>
| <properties>
| <property name="hibernate.dialect"
| value="org.hibernate.dialect.Oracle9iDialect" />
| <property name="hibernate.hbm2ddl.auto" value="update" />
| <property name="hibernate.ejb.cfgfile" value="/hibernate.cfg.xml" />
| <property name="hibernate.session_factory_name" value="java:/MyFactory" />
| <property name="hibernate.use_sql_comments" value="true" />
| <property name="hibernate.show_sql" value="true" />
| </properties>
| </persistence-unit>
|
and referencing this in jbpm.cfg.xml:
| <jbpm-context>
| <service name="persistence">
| <factory>
| <bean class="org.jbpm.persistence.jta.JtaDbPersistenceServiceFactory">
| <field name="sessionFactoryJndiName">
| <string value="java:/Argos3Factory" />
| </field>
| </bean>
| </factory>
| </service>
| ...
|
seems to help.
And never forget to inject the container's Hibernate session into the JbpmContext.

[JBoss Portal] - Is this a JBP 2.6.1 bug? (403 Error From Dashboard Link)
by NM-156
I have a custom JAAS LoginModule configured for JBP 2.6.1, running in AS 4.0.5. After logging in, everything looks alright with the page. The only problem is that when I click the Dashboard link, I get a 403 Access Denied error. I have added Authenticated, Users, & Admin roles to the user in my LoginModule, and I see "Logged in as 'my user'" and also I have the Dashboard | Admin |Logout links on the page after signing in.
The Admin and Logout links work correctly. When I click on the Dashboard link, I get the 403 error, but there are no exceptions when I check the log.
Is it possible that this is a bug in JBP 2.6.1? If not, is there any way to turn on a lower level trace? I do not see anything in the LoginModule examples that would imply that it is necessary to link a user with a dashboard, programmatically speaking.
Here is my LoginModule. Can you please let me know if the 403 is due to a bug in the portal, or if I am doing something wrong when adding the roles (see getRoleSets())? Thank you for any light that you can shed.
