[Beginner's Corner] - Re: JBoss (Apr) jboss-native :: linux
by rbrtfreund
Thanks for the help! Still in the same situation. It doesn't seem to pick it up no matter how I try it.
| The Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: /opt/jboss4/lib
|
How can I check or set where it looks for libraries to load. It's obvious from all the forums/ blogs/ irc / etc... that something isn't being loaded. Didn't have this problem on win only on linux. Is there some way to debug what's going on with this better? I already enabled the apache debug which provides me this

but still in the same spot. Any more ideas on where(what) to check?

=== Problem description =========================
Hi,
the errors above appears after starting the process via the jBPM console.
Is my process definition wrong? I would like to check if a service is running and proceed afterwards.
The problems seems to be located at the timer.
Thanks for your help. I'm new to jBPM and open for any solutions.
Greetings,
Jonas

[JBoss Web Services Users] - Newbie: Empty ArrayList Passed on WS Call
by gwzoller
Hello,
I'm having some difficulty getting a list of things passed successfully as a web service parameter. A no-param, or simple (non-list) param works fine. My web service is an EJB stateless session bean...code below.
The Interface:
| @Remote
| @WebService
| @SOAPBinding(style = SOAPBinding.Style.RPC)
| public interface OrderTakerRemote {
| @WebMethod
| public String msg(ArrayList<String> say);
| }
The Implementation:
| @WebService(endpointInterface="com.kepler.ecom.services.OrderTakerRemote")
| @Stateless
| public class OrderTaker implements OrderTakerRemote {
|
| // Default constructor.
| public OrderTaker() {
| }
|
| public String msg(ArrayList<String> say) {
| StringBuffer sb = new StringBuffer();
| System.out.println(say.size()); // verify non-emtpy list
| if( say != null ) {
| sb.append("Hey you says ");
| for(String one : say ) {
| sb.append("\""+one+"\" ");
| }
| }
| return sb.toString();
| }
| }
The Client:
| private void wsPlaceOrder() {
| String endpointURI ="http://127.0.0.1:8080/keplerEAR-kepler/OrderTaker?wsdl";
| try
| {
| ArrayList<String> stuff = new ArrayList<String>();
| stuff.add("One");
| stuff.add("Two");
| stuff.add("Three");
| this.wsOrderResult = (String) getPort(endpointURI).msg(stuff);
| } catch (MalformedURLException e) {
| e.printStackTrace();
| throw new RuntimeException(e);
| }
| }
The ArrayList is clearly created and populated in the client. The call is made...no errors on the console..and I do get a result string back, but its just the little header "Hey you says"...not the rest of it. The console output from the implementation showing the received list size prints 0.
Any ideas why my list isn't going over the wire?
Thanks!
Greg

[JMX] - How to add listeners for notifications
by menegazzo
Hello,
I'm trying to create a notification listener, is there any reference about notification types and how to structure the XML file?
I found this:
http://www.jboss.org/community/wiki/ExampleMinimalNotificationListener
But i would like to know where to find a complete reference, or at least another examples.
| <server>
| <mbean code="br.com.framework.scheduler.SchedulerService" name="framework.scheduler:service=SchedulerService" xmbean-dd="">
| <xmbean>
| <description>starts scheduler</description>
| <class>br.com.framework.scheduler.SchedulerService</class>
|
| <!-- Attributes -->
| <attribute name="SubscriptionList">
| <subscription-list>
| <mbean name="*:*">
| <notification type="JBOSS_MONITOR_NOTIFICATION"></notification>
| <notification type="JMX.mbean.registered"></notification>
| </mbean>
| </subscription-list>
| </attribute>
|
| <!-- Operations -->
| <operation>
| <description>Start service</description>
| <name>start</name>
| </operation>
| <operation>
| <description>Stop service</description>
| <name>stop</name>
| </operation>
| </xmbean>
| </mbean>
| </server>
|
The code above does not work, it says my xml is malformed (Field value invalid: name=null), but i cant see where it is this error.
Thanks in advance

[jBPM Users] - Re: jBPM-4.2 Remote API problem?
by markroy
My jbpm.cfg.xml under JBoss is:
| <?xml version="1.0" encoding="UTF-8"?>
|
| <jbpm-configuration jndi-name="java:/ProcessEngine">
|
| <import resource="jbpm.default.cfg.xml" />
| <import resource="jbpm.businesscalendar.cfg.xml" />
| <import resource="jbpm.tx.jta.cfg.xml" />
| <import resource="jbpm.jpdl.cfg.xml" />
| <import resource="jbpm.identity.cfg.xml" />
| <import resource="jbpm.jobexecutor.cfg.xml" />
| <import resource="jbpm.console.cfg.xml" />
|
| </jbpm-configuration>
|
which imports jbpm.default.cfg.xml, but I explictly added
| <process-engine-context>
| <object class="org.jbpm.pvm.internal.id.DatabaseIdComposer" init="eager" />
| </process-engine-context>
|
I see this in server.log
| DEBUG [org.jbpm.jboss.internal.JbpmService] (main) JbpmService starting...
| DEBUG [org.jbpm.pvm.internal.cfg.ProcessEngineImpl] (main) jndi name java:/ProcessEngine is not bound
| DEBUG [org.jbpm.pvm.internal.wire.WireContext] (main) eagerly initializing org.jbpm.pvm.internal.id.DatabaseIdComposer
| DEBUG [org.jbpm.pvm.internal.wire.WireContext] (main) eagerly initializing org.jbpm.pvm.internal.jobexecutor.JobExecutor
| DEBUG [org.jbpm.pvm.internal.cfg.ProcessEngineImpl] (main) publishing jBPM ProcessEngine in jndi at java:/ProcessEngine
|
so, that seems to be loaded, but I still get the same problem.
It doesn't make sense to me that the database should be checked (checkDb()) locally (at the 'client side'), but I added DatabaseIdComposer to that jbpm.cfg.xml anyway. Same problem. The client side of the remote API doesn't necessarily have a connection to the database. Shouldn't checkDb() be executed at the remote (JBoss) end?

[JMX] - Re: Question about queues / topics and MBeans

Hello, please check this:

Other useful links:
Do you need an assynchronous message system?

Or a simple solution like a scheduler?

| As with most things in JBoss, JMS Topics and Queues are implemented using MBeans. There are two ways you can create them: you can add MBean declarations to the appropriate configuration file, or you can create them dynamically using the JMX Console. However, if you use the latter method, they wont survive a server restart.

I'm new to all this stuff too, but i think JMX MBeans were designed to provide interfaces for management through administration consoles and other stuff.

By design, this standard is suitable for adapting legacy systems, implementing new management and monitoring solutions, and plugging into those of the future.
