[Design of JBoss ESB] - Re: Registry Design

If so, can't we rely on the container clustering capabilities? Also, what are we talking about here? We're not building a registry. We're simply generalising a registry Inquiry abstraction that acts as a facade to some underlying concrete implementation (UDDI etc). In reality, if that underlying concrete impl is not clusterable, there's no big gain in clustering the facade! Yeah/no??

[Design of JBoss ESB] - Re: Registry Design

by mugdho

Okay. So now we are getting somewhere :-)). So... The Inquiry needs to be abstracted using SOAP. The Updates will be thru the Admin Console and wouldn't need abstraction. The Service Security is for the ESB has a whole and we will need to work it out together. Next thing that I can think of is the Distributed nature of the Registry. Clustered Registry I should say.

[Design of AOP on JBoss (Aspects/JBoss)] - Re: using CallLoggingInterceptor on existing web app

by cpmcda01

This is an old post, but I'm resurrecting it because it seems it was never resolved, and I think I know why. The following code in CallLoggingInterceptor is evaluating to false: | boolean callLogging = log.isDebugEnabled(); | if (callLogging) | callLogging = Boolean.valueOf((String)invocation.getMetaData(LOGGING, | CALL_LOGGING)).booleanValue(); | First, let me say that key configuration like this should be mentioned in the Javadoc API for this class. I spent nearly two days trying to get call logging to work and all the while I kept thinking that JBoss AOP was broken or I was doing something fundamentally wrong. I can not express how frustrated I was and how much my impression of the JBoss product diminished when I found that the source of the problem was buried in the interceptor code and was not reasonably documented. So I gave up and I made my own Interceptor, copy-pasting most of the code from CallLoggingInterceptor, leaving out the above. Everything is working fine. Curious as to how this meta-data stuff worked, I went to the JBoss AOP documentation and found it sorely lacking. See for yourself: http://labs.jboss.com/portal/jbossaop/docs/1.5.0.GA/docs/aspect-framework... How would I configure this meta-data in my -aop.xml file to get the CallLoggingInterceptor to actually log something?

[Design of JBoss ESB] - Re: Registry Design

by tfennelly

anonymous wrote : How about the users trying to add a new service to be registered? We would need to provide a way for that I guess. Perhaps thru an admin console? Exactly! I'd expect this type of info to be added to the registry via whatever admin console comes with the reg product.

But we can think of them when the security features are worked out :-)). Aye, I think "Service Security" is a bigger issue that needs to be solved for all services being plugged into the ESB. I'm not sure there's anything special about the registry in this regard.

then the trick with the wrapper bean seems much more elegant to me. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3966714#3966714 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3966714

can you see the logs by the following code somewhere ? if (session!=null) { | log.debug("fetching connection from hibernate session. this transfers responsibility for closing the jdbc connection to the user!"); | connection = session.connection(); | mustConnectionBeClosed = false; | } | i remember beginning of this year, i searched 2 full days with gavin only to find out that session.connection transfers the responsibility for closing the connection from hibernate to the caller :-S View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3966711#3966711 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3966711

[Design of JBoss jBPM] - Re: Web App Error - No ManagedConnections available

by falazar

Yeah I saw that as the main reason suggested in a few other places, but I havnt, that I know of, changed any of the code that would effect that. The websale is running plain and simple, with no classes, just starting or moving a process instance on the webpage is causing it. I will get a thread dump later today and see what it shows. Thanks.

by kukeltje

agreed, I should have asked if it was on HEAD could it be that you forgot a JbpmContext.close() somewhere? Not sure if that causes these symptoms, just a wild guess. Maybe you can try to make a threaddump (search google how to do that) maybe that way we can see where this connectionleakage takes place.
