Using JBoss-6.0.0-SNAPSHOT, how can I specify the hibernate dialect to use for the DefaultDS?
The default hsqldb-ds.xml was replaced by this:
<?xml version="1.0" encoding="UTF-8"?>
<datasources>
<xa-datasource>
<jndi-name>DefaultDS</jndi-name>
<track-connection-by-tx/>
<isSameRM-override-value>false</isSameRM-override-value>
<xa-datasource-class>com.informix.jdbcx.IfxXADataSource</xa-datasource-class>
<xa-datasource-property name="IfxIFXHOST">sb2000</xa-datasource-property>
<xa-datasource-property name="PortNumber">9088</xa-datasource-property>
<xa-datasource-property name="DatabaseName">jboss6</xa-datasource-property>
<xa-datasource-property name="ServerName">sb2000_net</xa-datasource-property>
<xa-datasource-property name="User">xxx</xa-datasource-property>
<xa-datasource-property name="Password">xxx</xa-datasource-property>
<xa-datasource-property name="IfxLOBCACHE">-1</xa-datasource-property>
<user-name>xxx</user-name>
<password>xxx</password>
<exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.InformixExceptionSorter</exception-sorter-class-name>
<metadata>
<type-mapping>InformixDB</type-mapping>
</metadata>
</xa-datasource>
</datasources>
Using a database config from an ear file, the ear comes with an persistence.xml file which specifies the hibernate dialect, as InformixDialect in this case.

Even if I increase the heap size and adjust the NewSize to 1/3 I always get a rising graph.
In the article it says Heap usage has stabilize with both the heap usage before collection and after collection forming horizontal lines
In my situation do I still have to increase the heap size more?

Hi i created a new element escalation which acts as transition itself.. i parsed it similar to trasition in JpdlParser.java...i also have a new attribute 'level' in it public void parseEscalation(Element element, ActivityImpl activity, Parse parse) { UnresolvedTransitions unresolvedTransitions = parse.contextStackFind(UnresolvedTransitions.class); // HistoryActivityInstanceImpl hist = new HistoryActivityInstanceImpl(); List transitionElements = XmlUtil.elements(element, "escalation"); for (Element transitionElement : transitionElements) { String transitionName = XmlUtil.attribute(transitionElement, "name"); String level = XmlUtil.attribute(transitionElement, "level"); Element timerElement = XmlUtil.element(transitionElement, "timer"); if (timerElement != null) { TimerDefinitionImpl timerDefinitionImpl = parseTimerDefinition(timerElement, parse, activity); timerDefinitionImpl.setSignalName(transitionName); } TransitionImpl transition = activity.createOutgoingTransition(); transition.setName(transitionName); System.out.println("level#######>>>>>"+level); transition.setLevel(level== null || level ==""?0:Integer.parseInt(level)); // hist.setEscalationLevel(transition.getLevel()); // HistoryEvent.fire(new ActivityEnd(transitionName,transition.getLevel()),execution); unresolvedTransitions.add(transition, transitionElement); parseOnEvent(transitionElement, parse, transition, Event.TAKE); } could anyone please guide me how to save the attribute 'levels' value in JBPM4_HIST_ACTINST which will come for all escalation and the escaation name will come in the TRANSITION_ field.. i have added a new field ESCALATION_LEVEL_ in the table ..

[EJB 3.0] - optional OneToOne relation
by Frank Langelage

"optional OneToOne relation"

--------------------------------------------------------------
I have a entity with an optional unidirectional one-to-one relationship.
@Entity
@IdClass( value = MbiMsgpa.PK.class )
@Table( name = "mbi_msgpa" )
public class MbiMsgpa implements Serializable, Comparable<MbiMsgpa>
...
/** Relation with MbiMsgpt. */
@OneToOne( cascade = { CascadeType.PERSIST, CascadeType.REMOVE }, fetch = FetchType.LAZY )
@Cascade( value = org.hibernate.annotations.CascadeType.DELETE_ORPHAN )
@NotFound( action = NotFoundAction.IGNORE )
@PrimaryKeyJoinColumns( {
@PrimaryKeyJoinColumn( name = "msghd_serial", referencedColumnName = "msghd_serial" ),
@PrimaryKeyJoinColumn( name = "part_no", referencedColumnName = "part_no" )
} )
private MbiMsgpt mbiMsgpt;
...
}
This worked using JBoss-4.2.4, but migrating to JBoss-6.0.0.
But using JBoss6 I get an exception like this:
