How does it work? | A ha-singleton binds its location (ip address + port) to ha-jndi. The load balancing policy does a ha-jndi lookup of the singleton node and does a little magic to determine which server target is the singleton. Perhaps this could be combined with the JBAS-4455 solution, although it might be easier to understand for application developers to have separate solutions.

[Design of JBoss Web Services] - Merging PortComponentRefs

by scott.stark＠jboss.org

Some regressions in the metadata project have shown up due to how spec/jboss port-component-ref elements are merged. How should the following be merged: | <application-client xmlns="http://java.sun.com/xml/ns/j2ee" | xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | version="1.4" | xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/application-client_1_4.xsd"> | <display-name>BeanMirrorSEIClient_client</display-name> | <service-ref> | <service-ref-name>service/beanMirrorSEI</service-ref-name> | <service-interface>javax.xml.rpc.Service</service-interface> | <wsdl-file>META-INF/wsdl/BeanMirrorSEI.wsdl</wsdl-file> | <jaxrpc-mapping-file>BeanMirrorSEI.xml</jaxrpc-mapping-file> | <port-component-ref> | <service-endpoint-interface>com.sun.ts.tests.webservices.deploy.beanMirrorSEI.HelloWs</service-endpoint-interface> | </port-component-ref> | </service-ref> | </application-client> | | <jboss-client> | <jndi-name>BeanMirrorSEIClient_client</jndi-name> | <service-ref> | <service-ref-name>service/beanMirrorSEI</service-ref-name> | <port-component-ref> | <service-endpoint-interface>com.sun.ts.tests.webservices.deploy.beanMirrorSEI.HelloWs</service-endpoint-interface> | <port-qname>{http://BeanMirrorSEI.org}HelloWsPort</port-qname> | </port-component-ref> | <wsdl-override>http://localhost:8080/BeanMirrorSEIWeb/ws4ee/beanMirrorSEI?WSDL</wsdl-override> | </service-ref> | </jboss-client> | I assume there should be one JBossPortComponentRef with the service-endpoint-interface overriden(although here its the same value). Right now two are showing up in the ApplicationClient14UnitTestCase.testServiceRef View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4101424#4101424 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4101424

[Design of the JBoss EJB Container] - Re: Feedback requested on throttling ejb calls

by scott.stark＠jboss.org

Even more generically this should just be an aop aspect that can be applied to any component. Could even be a generalization of the org.jboss.aspects.asynch.* aspect in the aspect project.

[Design of JBoss Remoting, Unified Invokers] - Interceptor API

by david.lloyd＠jboss.com

I've committed the interceptor API into the Remoting 3 API module. I've removed the transaction and authentication methods from Context and created interceptor service interfaces for each of these. They are SecurityService and TxnService, both in org.jboss.cx.remoting.servce.

[Design of JBoss Portal] - Re: optimistick locking configuration with hibernate and jbo

by prabhat.jha＠jboss.com

There are few more things to be done: OptimisticTreeCacheProvider looks for treecache.xml in classpath and currently this is not configurable. So, either we need to have a similar implementation in portal that can read TreeCache definition from jboss-service.xml or some configurable locaton OR we need to create org.jboss.portal.jems.hibernate.JBossOptimisticTreeCacheProvider similar to org.jboss.portal.jems.hibernate.JBossTreeCacheProvider so that it looks for already deployed TreeCache mbean (the one defined through treecache.xml).

[Design of the JBoss EJB Container] - Feedback requested on throttling ejb calls

by ScottMarlowNovell

Hi, I want to allow EJB method invocations to be throttled as a way to reduce concurrency in applications. My first attempt at this is working great (I'm throttling at the PooledInvoker level for remote invocations only). This is intended for session bean level throttling. Lately, I've been thinking that it might be more appropriate to throttle at the EJB interceptor level instead so that applications can tailor throttling at the ejb container level. Should I switch to throttling at the interceptor level and should the throttle interceptor code be checked into 4.x or 5.x?

[Design of JBossCache] - Re: Proxy Based POJOs (No AOP) in POJO Cache

by vincent.marquez

Ok, the config value is something I can add. I didn't see a JIRA issue for this so if its alright with everyone i'll go ahead and add it, then post a patch to it for review.

[Design of the JBoss Web Container] - Digging under the servlet api - howto help

by parki

Hello! Just new to JBoss, and loving it, especially RichFaces, which is really tops. We have a related project, and I'd like to host this app in JBoss as well, but wondering about how to implement. There is a device (which we are building) which needs to open an HTTPs session to the proposed app in JBoss - the intention is to keep the connection open, and send/receive XML packets across this connection. So, we can't use the servlet api, as the outputStream will be flushed and can be cleaned up after a response - we need to keep a reference to the input and output streams and manage ourselves. Thus, I think we need to get under the Servlet API layer, and take more control over the connection. Can anyone point me to where in JBoss this gets handled? A simple example would be awesome, but even just a quick blurb and pointers into the classes within JBoss that we'd need to be aware of will greatly help. Many thanks - appreciated. parki...
