New Embedded Prototype

alrubinger Nov 20, 2008 5:20 AM

I've committed new jboss-embedded projects:

http://anonsvn.jboss.org/repos/jbossas/projects/embedded/trunk/

This is defined by:

https://jira.jboss.org/jira/browse/EMB-17

Included in this initial setup is a prototype of JBoss Embedded AS distribution which packages up AS and a few Embedded-specific classes into a single JAR, and successfully starts the AS Bootstrap.

Some points:

* Tangential to this is refactoring of the bootstrap project as defined by JBBOOT-4, where the common server locations (JBOSS_HOME, deploy, lib, etc) must be represented by VFS instead of java.io.File. This is required to get a server contained within a JAR.

* Embedded should really have no common server locations - it's got all of its binaries on the classpath and should be able to boot straight from there.

* I had to introduce a NoOpClassLoadingFactory to ignore any roots defined by classloading elements within the AS bootstrap. Due to the repackaging, these roots are not (and shouldn't be) found in the form they're listed. This furthers the notion that Embedded runs within a host ClassLoader.

I downloaded it and ran the package target and the test is failing with an OutOfMemoryError on some vfs copy:

Along with adding some more memory,
it's probably useful to set these two vfs config options:
-Djboss.vfs.cache=org.jboss.virtual.plugins.cache.TimedVFSCache
-Djboss.vfs.forceCopy=true

Should be fixed now.

Surefire plugin supports only 1 argLine, so values were getting overridden. Oddly enough my local machine doesn't need this configuration.
