Running Liferay on OracleAS 10.1.2

Liferay portal installation on OracleAS 10.1.2 doesn't necessarily follow the installation instructions mentioned in the liferay.com site.

Here are the rough steps to configure Liferay 3.0.6 on OracleAS 10.1.2. J2EE and Web Cache installation.

1. Download the Liferay EAR file. Follow the instructions to update the config files mentioned in the Liferay home pages.

2. Liferay uses different XML parser that is by default configured in OracleAS 10.1.2. To make the container use Xerces parser you need to set up parameters for starting up the container. Make sure you change the "/home/oracle/xerces/xerces-2_9_0" path to reflect your environment.

Edit opmn.xml:
         <ias-component id="OC4J">
            <process-type id="home" module-id="OC4J" status="enabled">
               <module-data>
                  <category id="start-parameters">
                     <data id="java-options" value="-server -Doc4j.userThreads=true -Djava.security.policy=$ORACLE_HOME/j2ee/home/config/java2.policy -Djava.awt.headless=true -Xbootclasspath/a:/home/oracle/xerces/xerces-2_9_0/xml-apis.jar -Dorg.xml.sax.driver=org.apache.xerces.parsers.SAXParser -Djavax.xml.parsers.SAXParserFactory=org.apache.xerces.jaxp.SAXParserFactoryImpl -Djavax.xml.parsers.TransformerFactory=org.apache.xalan.processor.TransformerFactoryImpl -Djavax.xml.transform.TransformerFactory=org.apache.xalan.processor.TransformerFactoryImpl"/>
                  </category>

After editing the opmn.xml manually, validate the opmn.xml with command:

$ORACLE_HOME/opmn/bin/opmnctl validate

Reload the changes in opmn with command

$ORACLE_HOME/opmn/bin/opmnctl reload

Update the dcm repository with command:

$ORACLE_HOME/dcm/bin/dcmctl updateconfig

3. Configure OC4J global-web-application.xml:

To avoid this exception:

OracleJSP: oracle.jsp.parse.JspParseException: /html/themes/brochure/templates/init.jsp: Line # 27, <theme:defineObjects />
Error: Tag attempted to define a bean which already exists: themeDisplay

Resolve: Add following in $ORACLE_HOME/j2ee/home/config/global-web-application.xml

<init-param>
  <param-name>req_time_introspection</param-name>
  <param-value>true</param-value>
</init-param>

4. Copy following jar files to $ORACLE_HOME/j2ee/home/applib

liferay-jdbc.jar
xercesImpl.jar
xml-apis.jar
xmlParserAPIs.jar

The link to Liferay's JDBC driver can be found from Liferay.com. Xerces parser can be downloaded from Apache.org site.

5. Bounce the OC4J container

6. Deploy Liferay EAR file using OracleAS Enterprise Manager.

Test and make sure everything works. If you have any additions, pls let me know and I'll update the notes here.

Looks like a new version of Liferay 4.x.x just popped out. You might give a shot and try above installation instructions with the latest release as well.
