[jBPM] - LDAP Authentication for JBPM Console

by John Sawyer

John Sawyer [http://community.jboss.org/people/mcsawyer] created the discussion "LDAP Authentication for JBPM Console" To view the discussion, visit: http://community.jboss.org/message/544174#544174 -------------------------------------------------------------- I need use LDAP for authentication & authorization. I'm using JBPM 4.3 I guess that customizing the identity component (i need create myIdentitySessionImpl) i can obtain authorization level... Ok.. but how can I change authentication? I have JBPM console (2.1 Snapshot), and I read that is using jaas, but I don't understand how is using jaas (maybe because my knowledge is zero...) I try to find any guide to help me to use LDAP with JBPM Cosole.. but i can't find anything... Can someone tell me, how can i move to ldap authentication? thank you! -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/544174#544174] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

I agree with you that is could be serious in consequences. Perhaps we could try to define as much as possible scenarios to try it. In addition provide really good documentation for it in dev or user guide. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/544169#544169] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [JBoss Microcontainer Development] - JBoss Reflect Performance Javassist vs Introspection

I can be found out easily from the raw method signature (I am already passing the SignatureKey into JavassistMethodInfo and using that in its equals() method to avoid having to load parameters there). Once something more advanced is called, then that could obtain the real typeinfo and delegate to that. I'm not 100% sure yet if this is what I want to do. I've looked more into this and will try out "lazy" type infos. When constructing the BeanInfos, it goes through and calls MethodInfo.getReturnType() and MethodInfo.getParameterTypes(). These calls are really heavy, and at least for this use-case we don't care about anything apart from the name. Behind the scenes, what happens for each parameter is: a) It hits the classpool to load the CtClass b) When creating the type info it needs to check if the class is an enum or annotation, the first time you call anything apart from CtClass.getName() it needs to load the underlying ClassFile. This is slow, but initialises the CtClass for future use. a) and b) seem to take about the same time, although b) probably varies with class size. I don't think we can do much about b) apart from trying to avoid it at all costs. Another observation in favour of optimizing the classpools further is needing to do this in JavassistTypeInfoFactory.get() (pseudocode) public TypeInfo get(ClassLoader cl, String name){ Cache cache = getCacheForLoader(cl); TypeInfo info = cache.get(name); if (info != null) return info; //The passed in classloader is not necessarily the one where the class lives, //so we need to hit the pool to find out where it comes from ClassPool pool = getPoolForLoader(cl); CtClass clazz = pool.get(name); if (clazz.getClassPool().getClassLoader() != cl) { cl = clazz.getClassPool().getClassLoader(); cache = getCacheForLoader(cl); info = cache.get(name); if (info != null) return info; } info = instantiate(clazz); cache.cache(info); return info; } We need to query the pool to figure out the correct classloader -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/544167#544167] Start a new discussion in JBoss Microcontainer Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

And this situation is worse than dead wait. Actually, I like the WHILE node of BPEL. But since I didn't know whether we could use GroupActivity in production environment, I don't want to risk. Finally, I am agree this feature is very useful. Even if we can't find the best solution, I will also vote yes on it. Thank you for your great work. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/544164#544164] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

So I want to wait for if somebody could give us other advice. At least we need consider about how to configure the related joinActivity, because if somebody forget to set the multiplicity attribute, then the execution will wait forever. I think that problem with modelling was mainly regarding for-each as new activity. If it comes to join activity, it is not quite as you described. If you don't set multiplicity attribute on join then first incoming transition will trigger execution to move on. Let's have a discussion about it and try to find best possible solution for it. I think it is quite important functionality in many processes. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/544161#544161] Start a new discussion in jBPM Development at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
