[JBoss Seam] - Re: missing conversation entry error
by gsegura
I'm sorry, pretending to make the code clearer I removed a rich:modalPanel used for confirmation, and it turns out there was actually the error.
as I posted before, the link was rendered by:
<s:div rendered="#{editorEmployee.employee.id!=null}">
| <h:commandLink id="btnEliminar" value="delete" action="#{editorEmployee.delete}"/>
| </s:div>
|
and the javascript code used to activate the link was:
| function doDelete() {
| window.location = document.getElementById('f:btnEliminar').href ;
| }
I couldn't found a way to trigger the link programmatically, directly assigning window.location apparently has not the same effect.
By time constraints to get around of my lack of knowledge of that js api I inserted a confirmation page instead.
Would be nice to know the correct way to use a rich:modalPanel to ask for confirmation, and then invoke h:commandLink, though.
anyway really thanks for your time

[JBossCache] - Using JBossCache on a Java Persistence with Hibernate standa
by newbeee
Hi There,
I am using JBossCache on a Java Persistence with Hibernate standalone program.
My persistence.xml file has
<persistence-unit name="ehiveimport" transaction-type="RESOURCE_LOCAL">
|
| <properties>
| <property name="hibernate.connection.url" value="jdbc:derby:importDB"/>
| <property name="hibernate.connection.driver_class" value="org.apache.derby.jdbc.EmbeddedDriver"/>
| <property name="hibernate.connection.password" value="importDB"/>
| <property name="hibernate.connection.username" value="importDB"/>
| <!-- <property name="hibernate.cache.provider_class" value="org.hibernate.cache.NoCacheProvider"/>-->
| <property name="hibernate.dialect" value="org.hibernate.dialect.DerbyDialect"/>
|
| <property name="hibernate.cache.use_second_level_cache" value="false"/>
| <!-- Provider is JBoss Cache with Optimistic locking -->
| <property name="hibernate.cache.provider_class" value="org.hibernate.cache.OptimisticTreeCacheProvider"/>
| <!-- JBoss Cache configuration file name -->
| <property name="hibernate.cache.provider_configuration_file_resource_path" value="jboss-cache.xml"/>
| <!-- Use query cache too -->
| <property name="hibernate.cache.use_query_cache" value="true"/>
|
| <property name="hibernate.transaction.manager_lookup_class" value="com.ehive.transaction.EHiveJBossTransactionManagerLookup"/>
|
| </properties>
|
| </persistence-unit>
And my jboss-cache.xml has
<?xml version="1.0" encoding="UTF-8" ?>
| <server>
| <classpath codebase="./lib/jboss" archives="jboss-cache-jdk50.jar, jgroups.jar" />
|
| <!-- ==================================================================== -->

|
| <!-- Max number of milliseconds to wait for a lock acquisition -->
| <attribute name="LockAcquisitionTimeout">15000</attribute>
|
|
|
| </mbean>
| </server>
In my entity beans I have
@Cache(usage = CacheConcurrencyStrategy.READ_ONLY)
Caching does not improve performance when I do a query entityManager.find(......)
With or without caching it takes same time.
Could you please let me know what am I missing and what needs to be done.
Thanks
