Re: [jboss-dev] Determining JBoss AS server version by examining install
Which is also available programatically via the java.lang.Package info
of org.jboss:
// Package information for org.jboss
Package jbossPackage = Package.getPackage("org.jboss");
System.out.println("JBoss " + jbossPackage.getImplementationVersion());
This includes the scm tag and build date. If you want the simple version
string, use the getSpecificationVersion() method. The jdk extcheck dumps
out the version header info of a jar:
[starksm@succubus bin]$ extcheck -verbose run.jar
Target file:run.jar
Specification title:JBossAS
Specification version:5.0.0.Beta3
Specification vendor:JBoss (http://www.jboss.org/)
Implementation version:5.0.0.Beta3 (build: SVNTag=JBoss_5_0_0_Beta3
date=200705030927)
Implementation vendor:JBoss.org

What about parsing the MANIFEST.MF file in JBOSS_HOME/bin/run.jar or
one
of the core jars in JBOSS_HOME/client/ or JBOSS_HOME/lib/?
