[Installation, Configuration & DEPLOYMENT] - direction of JBoss with osgi is what?
by deanhiller
I am looking at this ear file thing and see jars all over the place like so
myapp.ear
+-lib
....+- jars location 1
+ jars location 2
+ mywar.war
....+ WEB-INF
..........+- jars location 3
Well, I come from OSGi where everything is exposed as a shared library or a not shared library. It is very simple and there are really only those two choices. When a service, you may be accessible by some services and not others. I look at this ear file and think the following
1. jars location 3...okay, I get that, these are LIBRARIES only used in the war
2. Then there is jars location1 and 2 which is weird. jars location1 is like shared libraries. What is jars location 2 then? Are they shared or not?
Are they going to clean this up to the point where it is as easy as OSGi. In OSGi, every jar is either shared or not shared. when it is shared, the client then defines whether it is using that shared jar or just using it's own library. It is really quite simple and I thought JBoss 5 was using Osgi now, but it does not seem to have propagated up.
For those who don't know: in OSGi, in your shared library jar, you just define what packages are exposed and can be used in other services. In the other services jars, you just define what you import....if you have your own library, just don't import. It works beautifully and gives you the full power. I feel very limited in JBoss in that I cannot share my EJB layer between two ear files(and I hate ears....I wish it was just OSGi bundles and war files which covers just about everything including sar, har, jar, etc. etc. just by tweaking the manifest file).
Anyways, this is just my opinion but it would be nice to know the direction of JBoss and if it will catch up to the power of OSGi when it comes to Classloaders which is where OSGi rules on making the complicated simple.

[JBoss AOP] - Re: The use of Hotswapping
by aquatr7
Here is the content of the "jboss-aop.xml" file:
<?xml version="1.0" encoding="UTF-8"?>
| <aop>
| <prepare expr="execution(public * POJO->someMethod(..))"/>
| </aop>
In "execute" method I have deleted Per instance interception
| Advised advised = (Advised)pojo;
| advised._getInstanceAdvisor().insertInterceptor(new InstanceInterceptor());
| System.out.println("--- pojo.counter++; ---");
| pojo.counter++;
|
I created META-INF directory and moved "jboss-aop.xml" in it. I also modified the "-Djboss.aop.path" to point to the new location of "jboss-aop.xml". But it doesn't work.
So I tried the verbose mode, Here is the new configuration of "VM aguments":
anonymous wrote : -Djboss.aop.verbose=true -Djboss.aop.path=C:/Driverexemple/DynamicAOP/META-INF/jboss-aop.xml -javaagent:C:/aop/jboss-aop_1.5.6.GA/lib-50/jboss-aop-jdk50.jar=-hotSwap
I run the application and before the end of the "for" loop I modified "SimpleInterceptor" by "InstanceInterceptor".
The verbose mode display after 10000 without interception:
| --------------
| --- new POJO(); ---
| in empty constructor
| --- adding instance interceptors ---
| --- pojo.someMethod(); ---
| in someMethod
| --------------
| [trying to transform] SimpleInterceptor
| [debug] There are no caller pointcuts!
| [debug] was SimpleInterceptor converted: false

Thank you for the help.

[JBoss jBPM] - Re: Problem running bpel process designed with eclipse bpel
by alex.guizar＠jboss.com
I see two different problems.
13:50:20,215 ERROR [XPathEvaluator] selection of size other than one: []
This means one of your expressions is required to return a node-set of size 1, as described in the BPEL spec, but it returned an empty node-set (as evidenced by the empty string inside the square brackets []). Check your expressions. The server log file (jboss-4.x.x/server/default/log/server.log) will tell you which expression was being evaluated and help you pinpoint the problem.

This situation is known and documented. Please refer to section 3.5.2 "Transaction Manager" of the jBPM BPEL 1.1.1 manual for details.
