Instrumentable Class Loader for GlassFish #

The GlassFish server has support for Instrumentable Class Loader and it works only for EAR Environment. As Liferay is a web application the GlassFish must be configured with a Class Loader that is capable of Instrumentation required by Spring.

Configure context.xml and copy into META-INF directory of the deployed web application directory. For example, /opt/glassfish/domains/domain1/applications/j2ee-modules/liferay-portal/META-INF

 <Context path="/" >

<Loader loaderClass="org.springframework.instrument.classloading.tomcat.TomcatInstrumentableClassLoader" useSystemClassLoaderAsParent="false"/> </Context> }}}

Configure portal-ext.properties #

Configure portal-ext.properties with following parameters. Essentially, the following configuration enables JPA as persistence provider and informs JPA to use GlassFish related Load Time Weaver.

persistence.provider=jpa

transaction.isolation.portal=-1 jpa.load.time.weaver=org.springframework.instrument.classloading.glassfish.GlassFishLoadTimeWeaver}}}

Copy the “spring-instrument-tomcat.jar” #

Copy the “spring-instrument-tomcat.jar” file into GlassFish's server lib. Assuming that the GlassFish is installed under /opt/glassfish, copy the file into /opt/glassfish/lib. The file can be found in the "lib/development" directory of Liferay source tree.

Start the Server #

Start the GlassFish Server.

NOTE: Please use the jdbc configuration as usual for your choice of database
