[JNDI/Naming/Network] - How to Access EJB over HTTP in remote machine?
by ritesh163
hello everybody,
I am having problem to access EJB over HTTP in remote machine. I have to access EJB which is running in remote server. In between two EJBs, there is routing IP as these are running in different network connected by radio link. I am given with routing IP to connect with remote EJB by my client, that routing IP will map to remote EJB server.
Remote EJB server is running in [internal IP] and I have to connect remote EJB with [Routing IP or External IP]. Can I access this remote EJB over HTTP?
I am using JBoss-4.0.4.GA and Java version: 1.5.0_15. OS: RHEL 4.
If I access the web page through my server by "http://[routing IP]:[port]" then welcome screen of Jboss is displayed but through application, the connection is not found.
The code of client's remote machine for http-invoker.sar\META-INF\jboss-service.xml is given below:
| <server>
|
| <!-- The HTTP invoker service configration
| -->
| <mbean code="org.jboss.invocation.http.server.HttpInvoker"
| name="jboss:service=invoker,type=http">
| <!-- Use a URL of the form http://<hostname>:8080/invoker/EJBInvokerServlet
| where <hostname> is InetAddress.getHostname value on which the server
| is running.
|
| -->
|
| <attribute name="InvokerURL">http://[Internal IP]:[port]/invoker/EJBInvokerServlet</attribute>
| <attribute name="InvokerURLPrefix">http://</attribute>
| <attribute name="InvokerURLSuffix">:8080/invoker/EJBInvokerServlet</attribute>
| <attribute name="UseHostName">false</attribute>
| </mbean>
|
| <!-- Expose the Naming service interface via HTTP -->
| <mbean code="org.jboss.invocation.http.server.HttpProxyFactory"
| name="jboss:service=invoker,type=http,target=Naming">
| <!-- The Naming service we are proxying -->
| <attribute name="InvokerName">jboss:service=Naming</attribute>
| <!-- Compose the invoker URL from the cluster node address -->
| <!--
| -->
| <attribute name="InvokerURL">http://[Internal IP]:[port]/invoker/JMXInvokerServlet</attribute>
| <attribute name="InvokerURLPrefix">http://</attribute>
| <attribute name="InvokerURLSuffix">:8080/invoker/JMXInvokerServlet</attribute>
| <attribute name="UseHostName">false</attribute>
|
| <attribute name="ExportedInterface">org.jnp.interfaces.Naming</attribute>
| <attribute name="JndiName"></attribute>
| <attribute name="ClientInterceptors">
| <interceptors>
| <interceptor>org.jboss.proxy.ClientMethodInterceptor</interceptor>
| <interceptor>org.jboss.proxy.SecurityInterceptor</interceptor>
| <interceptor>org.jboss.naming.interceptors.ExceptionInterceptor</interceptor>
| <interceptor>org.jboss.invocation.InvokerInterceptor</interceptor>
| </interceptors>
| </attribute>
| </mbean>
|
| <!-- Expose the Naming service interface via clustered HTTP. This maps
| to the ReadOnlyJNDIFactory servlet URL
| -->
| <mbean code="org.jboss.invocation.http.server.HttpProxyFactory"
| name="jboss:service=invoker,type=http,target=Naming,readonly=true">
| <attribute name="InvokerURL">http://[Internal IP]:[port]/invoker/JMXInvokerServlet</attribute>
| <attribute name="InvokerName">jboss:service=Naming</attribute>
| <attribute name="InvokerURLPrefix">http://</attribute>
| <attribute name="InvokerURLSuffix">:8080/invoker/readonly/JMXInvokerServlet</attribute>
| <attribute name="UseHostName">false</attribute>
| <attribute name="ExportedInterface">org.jnp.interfaces.Naming</attribute>
| <attribute name="JndiName"></attribute>
| <attribute name="ClientInterceptors">
| <interceptors>
| <interceptor>org.jboss.proxy.ClientMethodInterceptor</interceptor>
| <interceptor>org.jboss.proxy.SecurityInterceptor</interceptor>
| <interceptor>org.jboss.naming.interceptors.ExceptionInterceptor</interceptor>
| <interceptor>org.jboss.invocation.InvokerInterceptor</interceptor>
| </interceptors>
| </attribute>
| </mbean>
| </server>
|
|
Also connecting code of my server is given below:
| props.put("java.naming.factory.initial",
| "org.jboss.naming.HttpNamingContextFactory");
| props.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
| props.put("java.naming.provider.url", "http://" + routingIP + ":"
| + port+ "/invoker/JNDIFactory");
|
| InitialContext ic = new InitialContext(props);
| Object objRef = ic.lookup("ejb/EjbTxn");
| ejbTxnHome home = (ejbTxnHome) PortableRemoteObject.narrow(
| objRef, ejbTxnHome.class);
| ejbTxn = home.create();
|
Will I have to use invoker in my server also or not? Error that occur during connection is also given below:

Could anyone tell me how to solve this problem ? If any suggest, please provide it to me.
Thank you.
