[jboss-user] [Beginners Corner] - Error when conecting with a remote object from MBean
Hello.
I have a remote server and a client in the form of an MBean, designed following
the Serialization Server example from JBoss Remoting.
The Server
| import javax.management.MBeanServer;
|
| import org.jboss.remoting.InvocationRequest;
| import org.jboss.remoting.InvokerLocator;
| import org.jboss.remoting.ServerInvocationHandler;
| import org.jboss.remoting.ServerInvoker;
| import org.jboss.remoting.callback.InvokerCallbackHandler;
| import org.jboss.remoting.transport.Connector;
|
| import ro.ebsoft.doorcontrol.comm.common.CommModuleMain;
| import ro.ebsoft.doorcontrol.interfaces.CommModule;
|
| public class Main {
|
| private static String transport = rmi;
| private static String host = localhost;
| private static int port = 5400;
|
| private static CommModule response;
|
| public void setupServer(String locatorURI) throws Exception {
| InvokerLocator locator = new InvokerLocator(locatorURI);
| System.out.println(Starting remoting server with locator URI
of:
| + locatorURI);
| Connector connector = new Connector(locator);
|
| connector.create();
|
| SampleInvocationHandler invocationHandler = new
SampleInvocationHandler();
| connector.addInvocationHandler(CommModule, invocationHandler);
|
| connector.start();
| }
|
| // rmi server main class
| public static void main(String args[]) {
|
| String locatorURI = transport + :// + host + : + port
| + /?serializationtype=jboss;
| Main main = new Main();
|
| try {
| response = new CommModuleMain();
| main.setupServer(locatorURI);
| while (true) {
| Thread.sleep(1000);
| }
| } catch (Exception e) {
| e.printStackTrace();
| }
| }
|
| public static class SampleInvocationHandler implements
| ServerInvocationHandler {
|
| @Override
| public void addListener(InvokerCallbackHandler arg0) {
| }
|
| @Override
| public Object invoke(InvocationRequest invocation) throws
Throwable {
| System.out.println(Invocation request is
| + invocation.getParameter());
|
| return new CommModuleMain();
| }
|
| @Override
| public void removeListener(InvokerCallbackHandler arg0) {
| }
|
| @Override
| public void setInvoker(ServerInvoker arg0) {
| }
|
| @Override
| public void setMBeanServer(MBeanServer arg0) {
| }
|
| }
| }
|
The MBean class
| package ro.ebsoft.doorcontrol.mbean.engine;
|
| import org.jboss.remoting.Client;
| import org.jboss.remoting.InvokerLocator;
| import org.jboss.system.ServiceMBeanSupport;
|
| import interfaces.CommModule;
|
| public class CommEngine extends ServiceMBeanSupport implements
CommEngineMBean {
|
| private static String transport = rmi;
| private static String host = localhost;
| private static int port = 5400;
|
| public String getMessage() {
| return message;
| }
|
| public void setMessage(String message) {
| this.message = message;
| }
|
| public void printMessage(){
| log.info(message);
| }
|
| protected void startService() throws Exception{
| log.info(Starting CommModuleMBean);
| String locatorURI = transport + :// + host + : + port +
/?serializationtype=jboss;
| log.info(Connecting to + locatorURI);
| //String locatorURI = transport + :// + host + : + port;
|
| InvokerLocator locator = new InvokerLocator(locatorURI);
| Client remotingClient = new Client(locator);
| remotingClient.connect();
|
| try{
| CommModule cm =
(CommModule)remotingClient.invoke(CommModule);
| }
| catch(Throwable t){
| t.printStackTrace();
| }
| }
|
| protected void stopService() throws Exception{
| log.info(Stopping with message: + message);
| }
|
| //setters getters
| }
|
When I run both the server and a similar client (which is not an MBean), all
goes well. But when I deploy my client as a .sar in the app server, I get

[jboss-user] [Remoting] - Need some advice
Hello and please excuse my total newbieness. I am building a web application that acts as a control panel to a collection of physical devices. I implemented the communication protocol as a RMI interface, whose methods are commands that need to be called from the web interface. The Remote object which acts as a RMI server resides on a host in the local network. The client should reside on the App Server. For what I understand from reading the JBoss Remoting docs, the idea should be that I have to implement a Service on the server who acts as a client to the remote RMI server. The Service will be used by my EJB session beans to send commands to the remote server, i.e. to the devices. Am I getting this right? If no, could you give me some tips? I'll be happy to provide further information if needed. Thank you for your time.

No, there isn't. Just the faces message posted above (model validation failed).

[jboss-user] [JBoss Seam] - Re: h:SelectManyListbox, s:SelectItems and Many-to-Many mapp
Pete, I tried your example posted here:
http://jroller.com/pmuir/entry/using_sets_in_jsf.
userGroup.xhtml now looks like this:
| h:selectManyListbox id=locationsListBox
value=#{dc:asList(userGroupHome.instance.locations)}
| disabled=#{not
s:hasRole('admin')}
| s:convertEntity /
| s:selectItems
value=#{locationList.resultList} var=location
|
label=#{location.locationName} noSelectionLabel=None /
| /h:selectManyListbox
|
where 'asList' is the function described in the link above.
Now, when trying to create a userGroup I get:
model validation failed:/members/userGroup.xhtml @33,44
value=#{dc:asList(userGroupHome.instance.locations)}: Illegal Syntax for Set
Operation
What am I missing?

[jboss-user] [JBoss Seam] - h:SelectManyListbox, s:SelectItems and Many-to-Many mapping
Hello.
Not sure if I'm addressing a known bug, but here it goes.
I'm using Seam 2.0.0.GA, JBoss AS 4.2.2, JDK 1.5
I have a Many-to-Many mapping:
Location entity:
| private CollectionUserGroup userGroups;
|
|
@ManyToMany(TargetEntity=ro.ebsoft.doorcontrol.applogic.entity.UserGroup.class,
| cascade={CascadeType.MERGE, CascadeType.PERSIST})
| @JoinTable(name=UserGroup_Location,
| [EMAIL PROTECTED](name=locationId)}, [EMAIL
PROTECTED](name=userGroupId)})
| public CollectionUserGroup getUserGroups() {
| return userGroups;
| }
|
| public void setUserGroups(CollectionUserGroup userGroups) {
| this.userGroups = userGroups;
| }
|
and UserGroup entity
| private CollectionLocation locations = null;
|
| @ManyToMany(
| cascade={CascadeType.PERSIST, CascadeType.MERGE},
| mappedBy=userGroups,
| targetEntity=Location.class
| )
| public CollectionLocation getLocations() {
| return locations;
| }
|
| public void setLocations(CollectionLocation locations) {
| this.locations = locations;
| }
|
|
When adding a new UserGroup, a user can select any number of locations for the
group.
userGroup.xhtml :
| h:selectManyListbox id=locationsListBox
value=#{userGroupHome.instance.locations}
| disabled=#{not s:hasRole('admin')}
| s:convertEntity/
| s:selectItems value=#{locationList.resultList} var=location
label=#{location.locationName}/
| /h:selectManyListbox
|
When I try to save a new group (for instance, with the 2 top locations from the
listbox), there's a failed validation. Faces Message: Conversion Error setting
value '0 1' for '#{userGroupHome.instance.locations}'.
I understand there's a problem binding a Set to a h:selectManyListBox (should
use ArrayList). When trying to change CollectionLocation locations; to
ArrayListLocation locations; Hibernate notifies that it does not support it
(mapping many to many to something else than a Collection).
What to do? Does anyone have a fix for this problem?
Thank you for your time.
