SUN TEAM Pl Help - Using EJB in JSC

When I posted the following, as of now there are over 33 viewers who still haven't replied yet. Could you guys help me out? I'm your spokensman around here in Auckland, planning to make JSC as a part and parcel of our Java curriculum.
The NetBeans 5.5 tutorial is out of sync with the IDE. However, with the IDE I created a simple sessionbean with one business method that returns a hardcoded value of type String. This was housed in a EJBModule called EJBModule1. I added this to Creator-2 and dragged the only method called m1() into the SessionBean of Creator-2. I included a button and a staticText and the code given below. Building the project was successful. When it was run, on clicking the button, the following error was displayed:
com.sun.data.provider.DataProviderException: java.lang.reflect.InvocationTargetException
The code:
public String button1_action() {
try {
String name = (String) getSessionBean1().getMySessionRemoteM15().getResultObject();
staticText1.setText(name);
} catch (Exception e) {error(e.toString());}
return null;
}

Thanx 4 responding Antonio, here comes what u hopefully required.

Thank You in Advance

We do have a sample app that demos this scenario.
Please check out:

Databases: Two Page Create, Retrieve, Update, and Delete (CRUD) Database Operations with Table Display
Two Page CRUD with Table Display is an application that demonstrates how to perform create, read, update, and delete operations on a cached rowset data provider. The data provider is bound to a JavaServer Faces table component. Rather than having functionality confined to one page, this application has two additional pages, one for creating a trip and another for updating a trip.

Help: Using EJB in Creator-2

The NetBeans 5.5 tutorial is out of sync with the IDE. However, with the IDE I created a simple sessionbean with one business method that returns a hardcoded value of type String. This was housed in a EJBModule called EJBModule1. I added this to Creator-2 and dragged the only method called m1() into the SessionBean of Creator-2. I included a button and a staticText and the code given below. Building the project was successful. When it was run, on clicking the button, the following error was displayed:
com.sun.data.provider.DataProviderException: java.lang.reflect.InvocationTargetException
The code:
public String button1_action() {
try {
String name = (String) getSessionBean1().getMySessionRemoteM15().getResultObject();
staticText1.setText(name);
} catch (Exception e) {error(e.toString());}
return null;
}

marysam,
I am trying to reproduce this, but I am curious as to how you deployed your EJB module, keeping in mid that NB 5.5 and JSC 2u1 use two different versions of the PE app server (9 versus 8.2). I intend to point NB at JSCs' app server, create and deploy the EJB module to PE 8.2 from NB 5.5, then consume the EJB per your description.

It turns out that the problem had to do with network accounts, even though it was not clear at first. Redirecting the program to the local machine's cache with a network home redirector script fixed the issue. Thanks anyway.

I need a clarification : Can I use EJBs instead of helper classes for better performance and less network traffic?

My application was designed based on MVC Architecture. But I made some changes to HMV base on my requirements. Servlet invoke helper classes, helper class uses EJBs to communicate with the database. Jsps also uses EJBs to backtrack the results.
I have two EJBs(Stateless), one Servlet, nearly 70 helperclasses, and nearly 800 jsps. Servlet acts as Controler and all database transactions done through EJBs only. Helper classes are having business logic. Based on the request relevant helper classed is invoked by the Servlet, and all database transactions are done through EJBs. Session scope is 'Page' only.
Now I am planning to use EJBs(for business logic) instead on Helper Classes. But before going to do that I need some clarification regarding Network traffic and for better usage of Container resources.
Please suggest me which method (is Helper classes or Using EJBs) is perferable
1) to get better performance and.
2) for less network traffic
3) for better container resource utilization
I thought if I use EJBs, then the network traffic will increase. Because every time it make a remote call to EJBs.
Please give detailed explanation.
thank you,
sudheer

Please suggest me which method (is Helper classes or Using EJBs) is perferable :
1) to get better performance
EJB's have quite a lot of overhead associated with them to support transactions and remoteability. A non-EJB helper class will almost always outperform an EJB. Often considerably. If you plan on making your 70 helper classes EJB's you should expect to see a dramatic decrease in maximum throughput.
2) for less network traffic
There should be no difference. Both architectures will probably make the exact same JDBC calls from the RDBMS's perspective. And since the EJB's and JSP's are co-located there won't be any other additional overhead there either. (You are co-locating your JSP's and EJB's, aren't you?)
3) for better container resource utilization
Again, the EJB version will consume a lot more container resources.

Ergent Help Using JBoss, EJBs ...

Hey to all ....
Please help me, i just started EJBs and i am having difficulties with the given project.
So ..
I am using EJB, Jboss too deploy everything
I have created my entities and some sessions.
Entities have created my database correctly.
Now i want to access the data from Jsp.
I Could use some help on that.
I am trying to create the JSP to call the sessions files that i have but i must be doing something wrong.
I have jared both entities and sessions and uploaded them in ejb container.
I am placing my jsp into the jsp container.
i am placing all classes into the web-inf container as well in the jsp container.
HOW will i get the data using the JSp ?
Please some help here.
Perhaps not the best post, but i have no idea what else too post

done it .... :)

Need help using XWS-Security with EJB service endpoint

I am trying to use XWS-Security along the lines of the JWSDP 1.6 examples, but with an EJB endpoint deployed in an ejb-jar file rather than a typical service endpoint deployed in a WAR.
Any information on how to do this would be appreciated. I believe I'm close to getting an example working- the details on the problem I've encountered are below.
I use WSCompile to generate stubs and ties for my WS, and XDoclet to generate the ejb-jar.xml. I deploy the ejb-jar on JBoss 4.0.2.
The problem I'm having is that the security features are handled in the Stubs and Ties generated by WSCompile, and my server-side refuses to use the WSCompile generated Tie. Previously the web service had used the WSCompile argument 'import="true"', which generated no tie, and the web service worked (this was before I tried to add security features). Whatever mechanism had been used to direct messages to my EJB then is still being used now (JNDI, I believe, facilitated by the ejb-jar.xml and webservices.xml files), and bypassing the Tie class that I now generate using 'server="true"'.
There must be some way I can reconfigure my webservice so that the WSCompile generated Tie is used, but I can't find any help on the topic.
Can anyone tell me how to make sure my webservice will use the Tie class on the server side? Is it even possible when using EJBs instead of servlets?

Burn your CD using iTunes. Then rip the music off of the CD using any "ripping" program. Just make sure the program you use has the "save as .wav" option available. Im not familiar with MusicMatch but I'm sure you would be able to use it.

Help - using custom login module with embedded jdev oc4j to access ejb 3

Hi All (Frank ??),
I'm just wondering if anyone has successfully been able to leverage a custom login module in combination
with a client that connects to a local EJB 3 stateless session bean through Jdeveloper 10.1.3.2's embedded oc4j.
I have spent 2+ days trying to get this to work - and i think I resound now to the fact im going to
have to deploy to oc4j standalone instead.
I got close.. but finally was trumped with the following error from the client trying to access the ejb:-
javax.naming.NoPermissionException: Not allowed to look up XXXXXX, check the namespace-access tag
setting in orion-application.xml for details.
Using the various guides available, I had no problem getting the custom login module working
with a local servlet running from JDev's embedded oc4j.. however with ejb - no such luck.
I have a roles table (possible values Member, Admin) - that maps to sr_Member and sr_Admin
respectively in various config files.
I'm using EJB 3 annotations for protecting methods .. for example
@RolesAllowed("sr_Member")
Steps that I had to do so far :-
In <jdevhome>\jdev\system\oracle.jwee.10.1.3.40.66\embedded-oc4j\config\system-jazn-data.xml1) Add custom login module

Thanks for the response. I checked out your blog and tried your suggestions. I'm sure it works well in standalone OC4J, but i was still unable to get it to function correctly from JDeveloper embedded.
Did you ever get the code working directly from JDeveloper?
Your custom code essentially seems to be the equivalent of a grant within system-jazn-data.xml.
For example, the following grant to a custom jaas role (JAAS_ADMIN) that gets added by my custom login module gives them rmi login access :-
 <grant>
 <grantee>
 <principals>
 <principal>
 <realm-name>jazn.com</realm-name>
 <type>role</type>
 <class>kr.security.principals.KRRolePrincipal</class>
 <name>JAAS_Admin</name>
 </principal>
 </principals>
 </grantee>
 <permissions>
 <permission>
 <class>com.evermind.server.rmi.RMIPermission</class>
 <name>login</name>
 </permission>
 </permissions>
 </grant>If I add the following to orion-application.xml

<namespace-access>
 <read-access>
 <namespace-resource root="">
 <security-role-mapping>
 <group name="JAAS_Admin"></group>
 </security-role-mapping>
 </namespace-resource>
 </read-access>Running a standalone client against the embedded jdev oc4j server gives the namespace-access error.
I tried out your code by essentially creating a static reference to a singleton class that does the role lookup/provisioning with rmi login grant :-
From custom login module :-
private static KRSecurityHelper singleton = new KRSecurityHelper();
protected Principal[] m_Principals;
 Vector v = new Vector();
 v.add(singleton.getCustomRmiConnectRole());
 // set principals in LoginModule
 m_Principals=(Principal[]) v.toArray(new Principal[v.size()]);
Singleton class :-

public RealmRole getCustomRmiConnectRole()
 return m_Role;
}Using the code approach and switching application.xml across so that namespace access is for the group remote_connect, I get the following error from my bean :-
INFO: Login permission not granted for current-workspace-app (test.user)
Thus, the login permission that I'm adding through the custom remote_connect role does not seem to work. Even if it did, i'm pretty sure I would still get that namespace error.
This has been such a frustrating process. All the custom login module samples using embedded JDeveloper show simple j2ee servlet protection based on settings in web.xml.
There are no samples showing jdeveloper embedded oc4j using ejb with custom login modules.
Hopefully the oc4j jdev gurus like Frank can write a paper that demonstrates this.

Help needed - why we use ejb-ref element in ejb-jar.xml

hi all
can anyone tell me what is the purpose of this element in the ejb deploy descriptor? thanks

Suppose u have bean A, which needs to look up another bean B. Normally you wud need to use the jndi lookup using the initial context to access the bean B's home interface. If you use ejb-ref element you dont need to know the JNDI name of bean B. You can use ejb-ref-name instead. So you can say this is a short cut method of looking up and getting a reference to a bean's home object.

Help using JMS in a network/general architecture

Hi everybody :
We are working on the development of a distributed application. The architecture of the system is something like this:
- A dispatcherthat receives requests (in a string shape) via http post. This unit has to encapsulate this request in a object and fordward such a petition to the correct service according a parameter of the request string.
- A little number of services (4 or 5) that wait for requests delivered by the dispatcher. When a petition arrives, is attended to, and a response is sent to the client, using the http post that the client has used to send us the initial request. The computation complexity could be severe (access to DB, on-demand compilations, multimedia handling...).
The distribution arises when we wanted to place each service on different machines due a heavy amount of requests.
On a first approach, we are considering to use a servlet to manage the requests and JMS as middleware messaging service, as we want to provide an efficient communication layer between the modules of our application.
Here come my doubts:
- Would be the system more efficient if the service-providers are some kind of Enterprise Java Beans? And servlets?
- I have readed the JMS and de JNDI tutorial. I have performed many tests in local mode, and i want now to do the same in a network mode... could somebody orient me? How do could i bind a connection factory with a specific resource across the network? In coding time or in deploying time?
Help will be very very appreciated!!!!!
Thank you very much for reading this message
Greetings from Maria, Spain (europe)

Hello Maria,
You mention several things regarding architecture. I'll try to iterate them for you. As always this is just one persons idea/opionion.
Receive Request from HTTP Posts. (Dispatcher)
-- Sounds like an XML String morphed into an object via servlet. You could standardize on SOAP if it's not too much overhead.
Services - High computation...
Let jms receive and queue these requests. A service delegate can spawn threads to deal with the complex computations. I say Queue so you can cap the active thread count and pause the delegators thread creation due to any memory / cpu constraints...
As far as JMS is concerned I'm unaware of your transactional requirements. In enterprise systems I have written, everything must be transacted and audited. JMS has a nice model for this. You could move to a pub/sub architecture as well.
Scalability - (Distribution arises) - Each machine can maintain it's own queue and the servlets can distribute to them. Or you can pub/sub them via a dispatcher, it's own machine if desired - and let each machine act as a listener. A nice model as the amount of services grows.
- Now that I've only reiterated what you've tried..
Would be the system more efficient if the service-providers are some kind of Enterprise Java Beans? And servlets?
-In my opionion for the high volume HTTP requests, servlets can lift the load.
-You system has a high level of requests and load on your CPU. I'll also assume that transactions and auditing are required. As I'm sure you well know EJB is not the fastest animal in the forest. I would not use Message Driven Beans as you will have a hard time tunning performance within an EJB Container.
- Now after I've said all that any fallout and persistance requrements from each service can leverage EJB's. Just remember that EJB's lend themselves well to web/commerce apps. I have no idea of your applications context so I'm taking a stab. There are wonderful tools in the EJB architecture, however, just because you've chosen Java doesn't mean you have to use EJB's. If speed in an issue for these services ( persisted or session level ) perhaps a mix is what your desire. ( I find session beans to be much better accessors than there sluggish entity brothers. )
JNDI - Create a Service Locator that abstract the lookups for your services. Depending on how far you want to go. Our Service Locator can look up a multitude of contexts. Be it Weblogic/Websphere or a file system. There is no magic to it you just have to plug and play the contexts.
"I have readed the JMS and de JNDI tutorial. I have performed many tests in local mode, and i want now to do the same in a network mode... could somebody orient me? How do could i bind a connection factory with a specific resource across the network? In coding time or in deploying time?"
--I would take the performance hit on late binding and use caching to try and gain some back. Below is a small example...
-- All in all, It would help you to become more familiar with the EJB spec if your planning on that path. You soon come to notice it's features ( and particular quirks ).
Good Luck,
Hope this helps

The .xml and code looks ok. Using java:comp/env is the right approach. How does getInitialContext() instantiate the InitialContext()? Make sure it's using the no-arg "new InitialContext" Also try running the $APS_HOME/bin/verifier on your .ear. Please also post the full stack trace. Thanks.

 out.println(" <table width='35%' border='0' cellpadding='1' cellspacing='1' bgcolor='#000000'> ");
 out.println(" <tr bordercolor='#000000' bgcolor='#CC99FF'> ");
 out.println(" <td width='19%' bgcolor='#CC99FF'>Name</td>");
 out.println(" <td width='81%' bgcolor='#CC99FF'>" + elem.getTitle() + "</td>");
 out.println(" </tr>");
 out.println(" <tr bordercolor='#000000' bgcolor='#CC99FF'> ");
 out.println(" <td>Message</td>");
 out.println(" <td>" + elem.getBody() + "</td>");
 out.println(" </tr>");
 out.println(" </table>");
 out.println("-----" + hm.get("title")); //I just want to try to get 1 item to see if it works
 out.println(" ");
 }Well thats the important parts of the code. it works fine when I send simple messages but when I try out the HashMap the servlet is displayed but no messages are sent to the queue. It would be great if anyone could help.
I know this isnt that clear but Im really tired and frustrated right now if you need more info please ask and I can supply it. Thanks

Hi, so I've added a weblogic-ejb.jar.xml file with a reference to the JNDI name of the work manager:
<?xml version="1.0" encoding="UTF-8"?>
<wls:weblogic-ejb-jar xmlns:wls="http://xmlns.oracle.com/weblogic/weblogic-ejb-jar" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd http://xmlns.oracle.com/weblogic/weblogic-ejb-jar http://xmlns.oracle.com/weblogic/weblogic-ejb-jar/1.0/weblogic-ejb-jar.xsd">
 <wls:weblogic-enterprise-bean>
 <wls:ejb-name>DependencyWorker</wls:ejb-name>
 <wls:resource-description>
 <wls:res-ref-name>MyWorkManager</wls:res-ref-name>
 <wls:jndi-name>wm/MyWorkManager</wls:jndi-name>
 </wls:resource-description>
 </wls:weblogic-enterprise-bean>
</wls:weblogic-ejb-jar>But I still get exactly the same error when I try to start my server. The example you referred to kind of cryptically suggests that adding a plan.xml suddenly fixed everything, but what am I missing here that actually hooks the work manager up to JNDI? am I getting these problems because I'm using annotations, or are people not supposed to access work managers in this way?
Thanks,

SUN TEAM URGENT: auto creation of data source, connection pool, ...etc

to the sun team,
i have been using NB+VWP to deploy an application created in JSCU2 to a Sun App Server 9.
for some reason, whenever am viewing a DB connection in the servers window and drag-drop a table on the page, the system is automatically creating a new data source, a new conneciton pool, and new jdbc resource. also, it is removing the necessary references in web.xml and sun-web.xml.
is there any way to get around this? otherwise, i am forced to modify the jdbc settings in the server as well as the config file each i drag-drop a DB table/view.
thanks so much
- Peter

Unfortunately, this is a bug and should be fixed in the next release.
I'll look for the issue id.
In the meantime, this workaround may help:
