BTW you should post such questions in the community forms https://community.jboss.org/community/jbossas7 https://community.jboss.org/en/jbossas7 otherwise you might not get an asnwer ;) --------------------------------------------------

The reason for this is because in domain mode there can be many servers belong to different server groups running different profiles. In that situation it's not clear to what server groups content in a "deployments" folder should be deployed. That requires knowledge beyond what a simple filesystem scanner has. > That's a clearer explanation of that point than I've stumbled into thusfar. So thanks for that. Can I configure a particular (controlled-by-domain) server to have a deployments dir? Let's assume the whole pile goes south. Power outage. Long one. So when I turn it back on, do I now have a manual process of re-deploying 40-some wars to their respective servers in server-groups? Or when I turn on each server via domain management, it will re-deploy what it had running last time it was shut down? See, I'm so used to JBoss 4.x and 5.x, and being able to just go look in the deploy dir to see what's there. If the war is in there, it unzips and runs when that particular instance is started. If it ain't there, it doesn't. The domain paradigm, in this regard, is still fuzzy to me. (As I google around, I see I'm not alone.) --------------------------------------------------

This would need to be taken into consideration, but I like the flexibility that Byteman usage would be able to add as use cases come up and different rules may need to be modified/added. > Maybe a hybrid solution would work. We use logging for the stuff that is already logged and Byteman for things that are not logged in the target release. Byteman could then produce a log message for what it finds, which would then be parsed by the latest version of the profiler. For example, we are (possibly) adding a new log message to Narayana 5.0.0.M4 which is needed by the profiler to construct an interposition hierarchy. This would mean that we can only use this on EAP versions with Narayana in (so not EAP 6.x). However, if we used Byteman to produce the log message, we could make it work with EAP 6 and prior. --------------------------------------------------

Re: [jboss-dev-forums] [JBoss AS 7 Development] - Multiple instances of JBoss AS7 on the same machine

kelvin0mql [https://community.jboss.org/people/kelvin0mql] commented on the document "Multiple instances of JBoss AS7 on the same machine" To view all comments on this document, visit: https://community.jboss.org/docs/DOC-16705#comment-12368 -------------------------------------------------- Apologies in advance for commandeering this topic. In our case, we have 1 war & 2 mysql datasources in deployments, and several dozen xml and properties files in configuration subdirs. It works in (copies of) standalone with almost zero config changes. Production is 4 physical boxes (more for UAT and QA), each with 8 or more JBoss servers running (over 40 wars, each for a customer). So - the standalone thing worked EASY. Now - I want to make use of the domain thing. One place to log into and control a half dozen other physical boxes, a couple dozen JBoss servers, several dozen wars, probably 4 or 5 server-groups. Where do I go to answer this: Standalone works. Twice. Different ports. Now how do I put them inside domain control? I expect there's a guide to migration from standalone to domain. Step by step. Or a class I can take. I can get two "servers" to come up inside the domain running, but it won't *deploy* anything. It *says* it does, but apache ajp connection still can't see it, and server.log doesn't say the "MYTHING.war deployed" like it does in standalone. Can't domain be configured to go control an already working standalone server? That's what we need. A lot. (will keep searching and reading) ~sigh~ --------------------------------------------------

Re: [jboss-dev-forums] [JBoss AS 7 Development] - Design of AS7 multi-JSF feature

by Stan Silvert

Stan Silvert [https://community.jboss.org/people/ssilvert] commented on the document "Design of AS7 multi-JSF feature" To view all comments on this document, visit: https://community.jboss.org/docs/DOC-47689#comment-12363 -------------------------------------------------- The permanent solution is in WildFly. See https://community.jboss.org/docs/DOC-48903 Design of WildFly Multi-JSF feature. There is a bit of tweaking required to get this working on AS7. Bruno, I think you used a version of jboss-jsf-installer that is meant for WildFly. The web-common module only exists in WildFly. I've added a tag to https://github.com/ssilvert/jboss-jsf-installer/tags the jboss-jsf-installer that works better with AS7. To use this version of the installer you will need to tell it the exact version of AS7 you are running. For example, +mvn -Djsf-version=2.1.8+ +-Dversion.jboss.as=7.2.0.Final+ +-Pmyfaces clean assembly:single+ To get this working in AS7 with CDI, you also need make some manual changes. See my earlier comment at https://community.jboss.org/docs/DOC-47689#comment-11484 https://community.jboss.org/wiki/DesignOfAS7Multi-JSFFeature#comment-11484. You'll need to make module.xml changes to get it working with Weld/CDI on AS7. --------------------------------------------------

[JBoss Microcontainer Development] - How to retrieve the relative classpath for Web app from classloader?

To view the discussion, visit: https://community.jboss.org/message/824990#824990 -------------------------------------------------------------- Hi there, I am trying to use Java compiler API with in Web application and it requires classpath information on the classloader which loaded all the JARs from WEB-INF/lib folder of web app. JBoss 5.1.0 uses VFS internally and its classloader somehow does not extend URLClassloader. Under these circumstances, how can I get Web Apps classloaders classpath info? Is there anyway, to configure System Classloader to be used for Web App ?

This ought to be a lot cheaper than globally switching on trace for the transactions code. Also, you should be able to print more info than is printed by the trace code. If you develop a simple helper jar you could also direct the data to a known location rather than having to trawl through the log. > This was my original plan for getting this working. However, it's not compatible with the requirement that: "we should be able to parse the customer submitted logs attached to support cases". I'd need to speak to GSS about this, but we could change the requirement to: "The customer should be able to easily provide a dump of the transactions to attach to a support case". Also, we were thinking that the logs should be complete. Therefore, all the information we gather should be present in the logs. If it isn't then we add it to the logs and then use it by the tool. However, I take your point that the Byteman approach is likely to be more powerful and performant. It's definitely something we should consider. --------------------------------------------------
