[jBPM Users] - Re: jBPM4 Sample Application

by kukeltje

But keep in mind, it is not fully finished yet. so building it your own might require some effort. And it might be that it already is in 4.1 (not tried the distribution yet myself) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4254090#4254090 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4254090

[jBPM Users] - jBPM4 Sample Application

by petitgitan

Hello everyone, An un-original question, but the answer escapes me nonetheless: is there a sample application that demonstrates the new paradigms in jBPM4? The examples that come with the distribution illustrate the usage of individual pieces. I couldn't find documentation or sample code that puts it all together. jBPM seems like a fantastic product, and fills a critical space in the open source realm, and it would be a pity to have lack of documentation as the main barrier to entry. Cheers, George View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4254059#4254059 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4254059

[jBPM Users] - Custom task in jbpm 4.1?

by Josh86

Hi, i am not so familiar with jbpm, and especially with jbpm 4. i have a question regarding custom tasks in jbpm 4.1. my problem is that before a task shoud be completed (taskService.completeTask ... ), another action should be done. For example a user task is signing a document, thus in this case a signature must be generated by user's private key and has to be saved in an external database, but this is out of scope of jbpm. But the thing is, before completion this taks, the signature must be saved. first idea was to to inherit from TaskImpl class and to override the complete method, but i think this would not work, because i cannot create my own Task Object and pass it to the jbpm api. But is there any good solution, which matchs the jbpm architecture and is a good object oriented design? Thanks for your answers, Josh View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4253717#4253717 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4253717

well, yes and no... this is debug level, trace shows (afaik) parsing of the jbpm config file(s). View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4253746#4253746 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4253746

Sorry, but could you run your app again with logging on TRACE level? Putting log4j for org.jbpm.pvm on trace level should be enough View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4253739#4253739 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4253739
