[JBoss Cache: Core Edition] - TimeoutException in a READ_ONLY Cache Entity
by fabianignacio
Hi
I'm facing a problem using TreeCacheProviderHook.
I have this Entity Bean:
| @Entity
| @Table(name = "MERCHANTCATEGORY")
| @Cache(usage=CacheConcurrencyStrategy.READ_ONLY)
| public class MerchantCategory implements Serializable {
|
| @Id
| @Column(name = "ID_MERCHANTCATEGORY", nullable = false)
| private Long idMerchantCategory;
|
| @Column(name = "CATEGORYNAME")
| private String category;
|
| @Column(name = "DESCRIPTION")
| private String description;
| }
|
With this persistence.xml
| <?xml version="1.0" encoding="UTF-8"?>
| <persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd">
| <persistence-unit name="PPSPU" transaction-type="JTA">
| <jta-data-source>java:/OracleDS</jta-data-source>
| <properties>
| <property name="hibernate.show_sql" value="true"/>
| <property name="hibernate.cache.provider_class" value="org.jboss.ejb3.entity.TreeCacheProviderHook"/>
| <property name="hibernate.treecache.mbean.object_name" value="jboss.cache:service=EJB3EntityTreeCache"/>
| </properties>
| </persistence-unit>
| </persistence>
|
In a JBoss 4.2.0GA.
I'm recieving this Exception, what I belive it shoudn't be like that, cause it's a READ_ONLY Cache:

At POSSettlementBean.java:186 I'm just calling a em.find() for another Entity (Merchant) that has MerchantCategory as a property
| merchant = em.find(pps.ejb.db.Merchant.class, idMerchant.longValue());
|
Do anyone know why JBoss Cache is locking a READ_ONLY Cache Entity?
Regards
Fabian

[Remoting] - Re: Which thread pool services SLSB requests in AS?
by ron.sigal＠jboss.com
Hi Justin,
You're in the right forum - the ServerThread you're looking at is an org.jboss.remoting.transport.socket.ServerThread, and the pool of ServerThreads is configured in the org.jboss.remoting.transport.socket.SocketServerInvoker that services EJB3s. The configuration is found in file $JBOSS_HOME/server/$CONFIG/deploy/ejb3.deployer/META-INF/jboss-service.xml, in particular, the lines
| <mbean code="org.jboss.remoting.transport.Connector"
| name="jboss.remoting:type=Connector,name=DefaultEjb3Connector,handler=ejb3">
| <depends>jboss.aop:service=AspectDeployer</depends>
| <attribute name="InvokerLocator">socket://${jboss.bind.address}:3873</attribute>
| <attribute name="Configuration">
| <handlers>
| <handler subsystem="AOP">org.jboss.aspects.remoting.AOPRemotingInvocationHandler</handler>
| </handlers>
| </attribute>
| </mbean>
|
If, for example, you want to increase the number of worker threads, append the "maxPoolSize" parameter to the InvokerLocator attribute:
| <attribute name="InvokerLocator">socket://${jboss.bind.address}:3873/?maxPoolSize=500</attribute>
|
For more information, see the Remoting Guide (http://www.jboss.org/jbossremoting/docs/guide/2.2/html/index.html), particularly Section 5.4.5. "Socket Invoker".
-Ron

[JBoss Portal] - 2.7.7CR Can't find resource for bundle... key LOGIN_TITLE
by jaykraly
I've been evaluating 2.6 and candidate release 2.7 running on JBoss 4.2.2GA. I built both from the source distribution with no errors.
When I hit localhost/portal on the 2.7 version, I get the following error, any ideas?
2008-10-02 14:56:32,499 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/portal].[jsp]] Servlet.service() for servlet jsp threw exception
