by ssidhanta
Hi,
I have solved the previous datasource error I was ghetting in my JBPM application---thanks to you all.But now I am getting a new error.
The server console log is as follows:

[Persistence, JBoss/CMP, Hibernate, Database] - org.hibernate.hql.ast.QuerySyntaxException: Terms is not map
by woezelmann
Hello,
I'm working on a dictionary-portlet and I'm using spring + hibernate.
For the SessionFactory I'm using the AnnotationSessionFactoryBean provied by spring. My application-context looks like this:
| <bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
| <property name="dataSource" ref="mssqlDataSource"/>
| <property name="hibernateProperties">
| <props>
| <prop key="current_session_context_class">thread</prop>
| <prop key="hbm2ddl.auto">validate</prop>
| <prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop>
| </props>
| </property>
| <property name="annotatedClasses">
| <list>
| <value>com.os.intranet.dictionary.persistent.Terms</value>
| </list>
| </property>
| </bean>
|
Runnig a query with JUnit works just fine: e.g.
session.createQuery("from Term");
But if I deploy my portlet on JBoss and run the same query, I get this error:
org.hibernate.hql.ast.QuerySyntaxException: Terms is not mapped [from Term]
Do someone have an idea what's wrong?
Regards
Chris

[JBoss Messaging] - JMS Issue
by bfach
Hello,
I am using 4.2.2.GA with 1.4.0SP3 Messaging. I connect to a JMS queue from a standalone client. It connects to the queue using ClusteredConnectionFactory.
What i have attempted is the ability to reconnect to a application server in the event that the server dies and returns. I am NOT talking about failover which allows to fail to another server. I am using failover as well but i want to reconnect to the same server in the event it is the only one in the cluster.
I have found that using the JMS ExceptionListener from the wiki works everytime with ConnectionFactory (not clustered) however only works once with the ClusteredConnectionFactory.
My first thoughts are that the attempted failover is causing issues with detection of a loss of connection.
Anyone who has any experience with this problem, it would be really appreciated.
Thanks in advance
