PVM does not let you to execute a process with out any restriction of language and any restriction of dependencies? The definition in jbpm.org is: The Process Virtual Machine is a simple Java library for building and executing process graphs. This serves as a basis for all kinds of workflow, Business Process Management (BPM) and orchestration process languages. So the PVM runs in all Java environments. Be it a standalone swing application, a web application on a servlet container like Tomcat, a spring environment or an enterprise application on an application server like JBoss. All of this with or without relational database persistence. And if you look the documentations and tutorials you can si how with a simple API you can create your own processes and execute them... Am I wrong? or this is what youhaodeyi is looking for? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4150436#...
