[JBoss Seam] - How to specify more than one persistence context in Componen
by gsawant
Hi
I am working on Seam 2.0 pojo, toplink, tomcat6. I got it working with one persistence unit where my components.xml and persistence.xml and context.xml file looked like below
components.xml
| <?xml version="1.0" encoding="UTF-8"?>
| <components xmlns="http://jboss.com/products/seam/components"
| xmlns:core="http://jboss.com/products/seam/core"
| xmlns:persistence="http://jboss.com/products/seam/persistence"
| xmlns:transaction="http://jboss.com/products/seam/transaction"
| xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
| xsi:schemaLocation="http://jboss.com/products/seam/core
| http://jboss.com/products/seam/core-2.0.xsd
| http://jboss.com/products/seam/transaction
| http://jboss.com/products/seam/transaction-2.0.xsd
| http://jboss.com/products/seam/persistence
| http://jboss.com/products/seam/persistence-2.0.xsd">
|
| <core:init debug="true" />
|
| <core:manager conversation-timeout="120000" />
|
| <transaction:entity-transaction entity-manager="#{em}" />
|
| <persistence:entity-manager-factory name="helloworld" />
|
| <persistence:managed-persistence-context name="em" auto-create="true"
| entity-manager-factory="#{helloworld}" />
|
| </components>
|
persistence.xml file
| <persistence 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 persistence_1_0.xsd" version="1.0">
| <persistence-unit name="helloworld" transaction-type="RESOURCE_LOCAL">
| <provider>oracle.toplink.essentials.PersistenceProvider</provider>
| <non-jta-data-source>java:comp/env/jdbc/PortalDS</non-jta-data-source>
| <class>Person</class>
| <properties>
| <property name="toplink.logging.level" value="FINE"/>
| <!-- <property name="toplink.ddl-generation" value="drop-and-create-tables"/> -->
| <property name="toplink.session.customizer" value="ToplinkSessionCustomizer"/>
| </properties>
| </persistence-unit>
| </persistence>
|
|
context.xml
| <Context path="/tomcatoratoplink" docBase="tomcatoratoplink"
| debug="5" reloadable="true" crossContext="true">
|
| <Resource name="jdbc/PortalDS" auth="Container" type="javax.sql.DataSource"
| maxActive="100" maxIdle="30" maxWait="10000"
| username="ghxmonitor_040200" password="ghxmonitor" driverClassName="oracle.jdbc.OracleDriver"
| url="jdbc:oracle:thin:@devdb10.ghx.com:1526:devdb1"/>
|
Now I made changes to persistence.xml and context .xml file to add one more persistence unit as follows
persistence.xml
| <persistence 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 persistence_1_0.xsd" version="1.0">
| <persistence-unit name="helloworld" transaction-type="RESOURCE_LOCAL">
| <provider>oracle.toplink.essentials.PersistenceProvider</provider>
| <non-jta-data-source>java:comp/env/jdbc/PortalDS</non-jta-data-source>
| <class>Person</class>
| <properties>
| <property name="toplink.logging.level" value="FINE"/>
| <!-- <property name="toplink.ddl-generation" value="drop-and-create-tables"/> -->
| <property name="toplink.session.customizer" value="ToplinkSessionCustomizer"/>
| </properties>
| </persistence-unit>
|
| <persistence-unit name="Registration" transaction-type="RESOURCE_LOCAL">
| <provider>oracle.toplink.essentials.PersistenceProvider</provider>
| <non-jta-data-source>java:comp/env/jdbc/SFRegistration</non-jta-data-source>
| <properties>
| <property name="toplink.logging.level" value="FINE"/>
| <property name="toplink.session.customizer" value="ToplinkSessionCustomizer"/>
| </properties>
| </persistence-unit>
| </persistence>
|
context.xml
| <Context path="/tomcatoratoplink" docBase="tomcatoratoplink"
| debug="5" reloadable="true" crossContext="true">
|
| <Resource name="jdbc/PortalDS" auth="Container" type="javax.sql.DataSource"
| maxActive="100" maxIdle="30" maxWait="10000"
| username="ghxmonitor_040200" password="ghxmonitor" driverClassName="oracle.jdbc.OracleDriver"
| url="jdbc:oracle:thin:@devdb10.ghx.com:1526:devdb1"/>
|
|
| <Resource name="jdbc/SFRegistration" auth="Container" type="javax.sql.DataSource"
| maxActive="100" maxIdle="30" maxWait="10000"
| username="reg_api" password="reg_api_pwd" driverClassName="oracle.jdbc.OracleDriver"
| url="jdbc:oracle:thin:@devdb10.ghx.com:1527:devdb1"/>
|
| </Context>
|
but I don't know how to specify another entity manager in components.xml for persistence unit "Registration".
Any help appreciated.
Thanks
Geeta

[JBoss jBPM] - Re: concurrency question

Yes I thought about that but in that case isn't there essentially two layers of hibernate helper code to get SessionFactory, session etc? i.e. your code and then the jbpm code? I thought that the way I suggested would reuse the fairly generic code already there. Also I presume that you will also need to use a thread local to hold a hibernate session for each thread?
So you just call getCurrentJbpmContext at some point and then set the session on it?
Also in terms of managing Hibernate config do you add your domain object mappings on the end of the jbpm mappings?
Thanks for you help.
