Running Geronimo on Harmony

This article describes the ways and known issues to run Geronimo v2.0.1 using Apache Harmony as a JVM.

ToDo

This article has the following structure:

General notes

Using DRLVM

You should use DRLVM (Harmony VM) to run Geronimo.

Harmony also supports IBM J9 VM, but Geronimo doesn't work with it, as Geronimo relies on java.util.concurrent package that requires a proper implementation of sun.misc.Unsafe class that is missing in IBM J9 VM.

Adjustments required in Geronimo

Adjust config.xml to use Harmony RMI Registry provider for JNDI

Harmony places JNDI providers in org.apache.harmony.jndi package tree, not in com.sun.jndi like Sun Java does, so you have to point Geronimo into the right direction to locate and properly access the RMI Registry provider.

For that, edit var/config/config.xml file, adjust NamingProperties GBean configuration as follows:

<gbean name="NamingProperties">
<attribute name="namingFactoryInitial">org.apache.harmony.jndi.provider.rmi.registry.RegistryContextFactory</attribute>
<attribute name="namingFactoryUrlPkgs">org.apache.harmony.jndi.provider</attribute>
<attribute name="namingProviderUrl">rmi://${ServerHostname}:${NamingPort + PortOffset}</attribute>
</gbean>
