Maybe this is not the right forum. I'll try to repost it to "Installation, Configuration & Deployment", but the issue is still of interest.
I had met the same question with you ,but as i know , the jbpm2.0 also need jdk1.4.
This is the right forum with regard to jbpm, so no worries.
I'm not sure about 3.0, but 3.1 needs jdk1.4 afaik, Recompiling might be an option, but not sure about the dependent libraries.
WL7? Migrating to 8.1 is easy, at least migrating from 6.0 to 8.1 was not to difficult in outr situation.
btw, http://java.sun.com/j2se/1.3/index.jsp, jdk 1.6 is almost there.
jbpm2.0 for sure does NOT need 1.4, but if you start using jbpm, we strongly advice not to start with 2.0
1) I confirm that jbpm2 works with JDK 1.3 (we have a working app in this environment).
2) Unfortunately we have to ship the project on current platform WL7. WL upgrade is a client decision and is on the way, but much to far for this project.
So the question is still open, or you are suggesting that there is no migration path?
there is indeed no easy migration between 2.0 and upwards. From 3.0 on, migration has gotten a lot more attention and priority, so from those versions on there is tooling.
That's really a problem.I believe you are right that the jbpm2.0 can be work with jdk1.3, but i want to say that i got the information from the jpbm2.0 doc,the chapter "Getting started" had refer as below:
Getting Started This page describes the fastest way to get jbpm up and running on your system, including the demo webapplication. Required software jBpm 2.0 is tested on a Windows XP machine with following software packages installed : * 'J2SE SDK v 1.4.2_03', downloaded from http://java.sun.com/j2se/1.4.2/download.html * 'Apache Ant version 1.6.1', downloaded from http://ant.apache.org/bindownload.cgi * Optionally, you can deploy jbpm on the JBoss j2ee server. 'JBoss 3.2.5', download from http://prdownloads.sourceforge.net/jboss/jboss-3.2.5.zip?download, unzip and set the JBOSS_HOME environment variable
do you expect anything from us?
