[jBPM Users] - JBPM 4.1 or 4.2 on Weblogic 9.2 -> Extra jars + unable to lo
by RockerRocker
Hi
I have deployed a JBPM (4.1) application on Weblogic 9.2 Server. After a lot of lib clean up , it works fine except for 2 issues -
1. Extra Libraries
POM file contains
<dependency>
| <groupId>org.jbpm.jbpm4</groupId>
| <artifactId>jbpm-jpdl</artifactId>
| <version>4.1</version>
| </dependency>
This downloads tons of libraries to my target/web-inf/lib folder during build.
Many of these cause conflict during deployment and are not needed (as i have other versions of those jars). I have to delete many jar files before deploying app on Weblogic 9.2. Has anyone deployed JBPM 4.1 or 4.2 w/o any such jar deletion/modifications ?? Can you share the POM file please.
2. When i start the server - i get the message - com.sun.faces.config.ConfigurationException: It appears the JSP version of the container is older than 2.1 and unable to locate the EL RI expression factory, com.sun.el.ExpressionFactoryImpl. If not using JSP or the EL RI, make sure the context initialization parameter, com.sun.faces.expressionFactory, is properly set.

When i remove the lines
<context-param>
| <param-name>com.sun.faces.expressionFactory</param-name>
| <param-value>com.sun.faces.ExpressionFactoryImpl</param-value>
| </context-param>
from web.xml and deploy again, it deploys w/o any issue

[jBPM Users] - Re: How to use timers?
by kukeltje
First of all, let me point you to http://catb.org/~esr/faqs/smart-questions.html#volume
Personally, when I started reading your post and encounter very basic questions with statements that are plain wrong (see further on, and my previous post) in combination with LOTS of data (will not call it information), I really hesitate to respond, but since I'm in a really good mood
anonymous wrote : The first problem I encounter is a "service 'scheduler' unavailable" error. Searching on the net I found some hints like "start the scheduler" or "change the configuration in src/main/config/jbpm.cfg.xml.
Isn't the internet great
anonymous wrote : But nobody explains WHAT is the scheduler,
Are you serious? You did not ever get the impression that it is used to execute timers? Strange since you have a problem with timers and a message that the scheduler is unavailable and you started searching in this direction. Oh, and it is in the first chapter of the user docs: http://docs.jboss.org/jbpm/v3/userguide/introduction.html#d0e130
anonymous wrote : how to start it, etc..
Besides in the docs: http://docs.jboss.org/jbpm/v3/userguide/deployment.html#webapplication
Very little searching yielded

and many more links
anonymous wrote : However, after some trials and debugging sessions I found that the solution to this problem is another one: you need to create a JbpmContext by yourself:
This is also very basic jBPM stuff and in almost all examples, getting started. So I it sounds strange to me that you only found this out through debugging.
anonymous wrote : However, as I'm working with no database at all, I wouldn't expect that.
You yourself might not be, but does it come as a surprise that jBPM might need one? jBPM is a statemachine, mainly for workflow, so long running processes. Most people would like that state to be persistent to survive a crash or restart. Most systems use a database for this (as does jBPM).
I hope this already helps you as I did not look into your two specific cases.
