[JBossCache] - Re: Caching for Web services?

by manik.surtani＠jboss.com

What specifically do you need to cache WRT. web services? And is the goal to cluster/share state? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3975467#3975467 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3975467

[JBossCache] - Re: Using TreeCache as a local cache solution

[Clustering/JBoss] - HASingleton & Service accessed directly with Service Method

by ju

Hi, I'm trying to access to a HASingleton Service through a HASingletonController. The thing is that I would like to use the Service methods directly and not be obliged to use the RMIAdaptor to call methods. I've read the http://www.jboss.org/index.html?module=bb&op=viewtopic&t=55794 thread and snoobabk was talking about a solution for my problem: anonymous wrote : You don't have to use the RMI interface to access the HA singleton but can use the actual objects interface. | | See http://www.mojaja.com/blog/default/development/2005/11/08/JBoss-HA-detach... unfortunately, the link is dead... Is the solution somewhere on the Wiki?

[Security & JAAS/JBoss] - Re: Intermittent losing of user principal in standalone Tomc

by rtosin

The problem is solved after I added multi-threaded="true" in auth.conf. Taken from http://wiki.jboss.org/wiki/Wiki.jsp?page=ClientLoginModule anonymous wrote : | When the multi-threaded option is set to true, each login thread has its own principal and credential storage. This is useful in client environments where multiple user identities are active in separate threads. When true, each separate thread must perform its own login. When set to false the login identity and credentials are global variables that apply to all threads in the VM. The default for this option is false. | Does it mean that embedded Tomcat and standalone Tomcat handle the thread in different way (since I'm using the same code but got different result when I deployed them in diff environment)? regards, View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3975444#3975444 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3975444

[JBoss jBPM] - Re: extending eclipse process designer plugin

by koen.aers＠jboss.com

Hi Paul and Sunil, Extending the designer is not really easy at the moment. There are a couple of extension points that allow you to do these kinds of things, but they are not documented and will probably change in the future. Have a look at the plugin.xml file of the org.jbpm.gd.jpdl.ui project. You will find the 'editPolicies' and 'graphElements' extension points. You can see how they are used in the following excerpts: <graphElement | name="state" | contributor="org.jbpm.ui.contributor.StateContributor"> | <entry | category="org.jbpm.palette.1.BasicNodeTools" | id="org.jbpm.ui.palette.2.State" | label="State" | tooltip="Creates a State node" | type="node"/> | </graphElement> | <editPolicy | id="org.jbpm.ui.NodeComponentEditPolicy" | part="org.jbpm.ui.part.graph.NodeGraphicalEditPart" | policy="org.jbpm.ui.policy.NodeComponentEditPolicy" | role="ComponentEditPolicy"/> | Certainly the use of the 'editPolicy' extension point (which serves to modify and customize the way graphical objects react to user input) requires a fair amount of GEF knowledge. Hopefully this helps.

[Persistence, JBoss/CMP, Hibernate, Database] - Re: Exception: CMR field value is already loaded

by Oyabun

We found the solution for our project. Because of the (old) architecture of our project, we are forced to use a non-standard configuration. That is, we use Standard CMP 2.x EntityBean with cache invalidation for our Entity Beans, with commit option A _and_ Optimistic Locking. The Wiki article http://wiki.jboss.org/wiki/Wiki.jsp?page=CMPCaching clearly states that when we want global caching we must use Pessimistic Locking (which is default btw.) The problem we had with Pessimistic Locking is that it produced a lot of "Application deadlock" errors so instead we opted for Optimistic Locking which gave us "CMR field value is already loaded". Our Session Beans use "Supports" by default for transaction type and "Required" only for methods which need to write to the database. Our Entity Beans were completely "Required". Since there was no need for the getter methods to be "Required", we made them read-only and "Supports" to make sure they don't start a new tx. We use Xdoclet: | * @ejb.transaction | * type="Supports" | * @jboss.method-attributes | * read-only="true" Read more about read-only here http://www.onjava.com/pub/a/onjava/2003/05/28/jboss_optimization.html This configuration worked for us. We think that due to our erroneous configuration, the CMP container tried to load data multiple times into the cache, which JBoss didn't allow. The new configuration doesn't start any tx for reading access (we traced it and know that). It also seems to behave correctly by loading instances only once into the cache and then reading from it too. Another solution is to use Instance Per Transaction CMP 2.x EntityBean but that is not acceptable because it's too slow. Hope that helped. -- Alex View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3975441#3975441 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=3975441
