We have a J2EE application deployed on JBOSS 4.0.0 on Solaris 8. The site starts properly without error. However we are facing problems in the way the jar files put in the lib folder is interpreted by JBOSS. Ideally the sequence/order of jar files should be alphabetically. This is the way it works on Windows environment also. Since this(sequence/order of jar files) is not happening in JBOSS on Solaris few of the overriden classes (packged in side the jar) don't appear in the classpath. Hence the application doesn't work as it supposed to.
