[Design of POJO Server] - Profile Service and Scanners

by adrian＠jboss.org

This is probably two seperate questions, but I'm going to deal with them together. Profile Service. The profile service api as it stands in terms of what is server side api and what is client side api (or even offline api), is not good. This really does need sorting out. Scanners. We appear to have two implements of the scanner. The first is the VFSScanner which is used during initial bootstrap to scan for the deployments. The second is the HDScanner. This asks the profile for modified deployments on a timer. But the profileimpl is doing its own checking for modifications. The deployments/files it should be checking, i.e. the rules configured in boostrap-beans.xml on the VFSXXXScanner aren't used. So the definition of what makes up the profile is different at bootstrap time to what it is during hotdeployment. My recommendation would be to move all this code into the VFSScanner and like the old scanner, we just generate "ADD" ModificationInfo events for the bootstrap using the HDScanner to do all invocations on the MainDeployer.

[Design of JBoss jBPM] - Re: adding Node to Process Instance at Runtime

by kukeltje

Yes you are right, it is a developers forum. What bug/feature of jBPM are you working on at the moment? It is a forum for developers OF jBPM, not developers working WITH jBPM. It is design OF jBPM, not designing WITH jBPM. The reason I asked you if you read any of the basic docs of jBPM is that you ask whether there is a GUI to design JPDL process flows... The answer to this is in ANY jBPM doc you will read. The productsheet (a 3 page pdf, accessible from the jBPM product page) has the info. Just like the INTRODUCTION part of the normal docs Regarding the question on JRules (realy JRules or JBoss Rules?) Try typing jbpm and rules in google... lots of info... or jbpm and drooles (shoot, could there be a wiki page for this? Naaahhhh I bet there isn't) The subject of the post covers all your questions perfectly by the way. The answer to this would be: By using the api or try e.g. google again... first post http://www.google.nl/search?q=jbpm+runtime+node+adding&btnG=Zoeken&hl=nl&... Oh.. and btw these 3 questions are all answered in the FAQ... wonder What the F stands for. What remains is your last question. See http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4006591#4006591 for a small answer...

[Design of POJO Server] - JBAS-4206 - ProfileService and TODOs about ClassLoader

by adrian＠jboss.org

We really need to decide what we are going to do about the classloader the deployers run under. In the old system everything ran under the conf/jboss-service.xml classloader which has a hook into the ULR. In the new system, we try to emulate this, but the profile service allows multiple bootstrap deployments so we just choose the "first one". This is obviously very hacky. But this isn't going to work with the OSGi style classloading. If the deployer's deployment doesn't export its deployment classes, the conf/jboss-service.xml classloader won't be able to see them. You'd have the same problem if a deployer was scoped with the ULR. What we really want is for each deployer to run under its own classloader, i.e. the one of the deployment where is was deployed. Assuming we do that, there's still the issue of what classloader the bootstrap runs under. In practice, the bootstrap classloader shouldn't be much of a problem. It should only be in play while the main deployer (structural and normal deployers) are determining what deployers to invoke. So we could just run it under the real bootstrap classloader, i.e. the one created by the ServerLoader? I think this would just require moving things like some of the dtds and schemas into the relevant jar, instead of them all being jboss.jar View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4064174#4064174 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4064174

[Design of JBoss Portal] - Re: current logged users

by bdaw

I wrote initial version of statistics service using concurrent libs (feature and executor framework). But I had no chance to even really test it before I needed to focus on something else. There was no front end. I should still have it somewhere on my HD hopefully. I can send it to you if you like (ping me by email or write your address here). Anyway - feel free to start from scratch if you want.

[Design of JBoss jBPM] - Re: adding Node to Process Instance at Runtime

by naganand76

Ofcourse, I do read them. But, sometimes its little out -of-scope. Becos, when you say Workflow Tool to the users; they start demanding all sorts usability. Since, mine is more of Rule Based Workflow; for me it would be good to use a Table or a JRule to define a condition and startoff the workflow. Anyways, its a developer forum. Thanks.

wrong forum... use the user forum for this. May I ask if you read anything about jBPM at all? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4064106#4064106 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4064106
