SNMP- WLS81SP1 ejb*RuntimeTable not working

We have several EJB's as part of EAR file.
When SNMP Agent is enabled we are able to query every Runtime Table
except EJB***Runtime Tables.
For example:
java snmpwalk -c public@lbs localhost .1.3.6.1.4.1.140.625.190.1
(JDBCPoolRuntime)
gives appropriate results.
But
java snmpwalk -c public@lbs 144.111.12.126 .1.3.6.1.4.1.140.625.170.1
(EJBStatelessHomeRuntime) returns with no output.
Every runtime table related to EJB gives no results.
Is this a bug with 81SP1? This used to work fine with 6.1SP4
Thanks In Advance,
Kumar.

Satya,
When I use Weblogic.Admin to query MBeans, I get "No MBeans found" for
all the stateless session beans and MDB's that are part of my ear file.
I am able to invoke these stateless session beans and MDB's are
processing messages.
Also I am able to see my web application that are part of same EAR
file when I query on type WebAppComponentRuntime.
Why are EJBMessageDrivenRuntime and EJBStatelessHomeRuntime not visible
that are part of same ear?
Thanks,
Kumar.

I just tried for EJBPoolRuntime and it worked with out any problem.
Could you make sure that you have EJBStatalessHomeRuntime mbeans in your
server. You can do that through
java weblogic.Admin -username xxx -password xxx -url t3://localhost:7001
get -type EJBStatelessHomeRuntime -pretty

Re: EJB Control not working with methods that contain arguments

John,
I'm not qualified to answer your EJB control question, but before you
become too disillusioned with page flows I'd like to mention that the
request scoped data form and and the return-to="page" issues you
mentioned have been addressed for the next service pack. We've
introduced the ability to specify a page flow scoped form bean which
lives for the life of the page flow, and we've clarified the return-to
values to include both "currentPage" and "previousPage" which should
clarify the expected behavior.
I hope you give it a try.

Can you just attach your stateless session bean. You need not sendthe
dependent files, since we only want to sniff the call made to the stateless
EJB method, and are not concerned with the implementation.

I am using the GA release. My control looks identicle toTraderEJBControl.jcx

itself does not exacly match the traderbean but it does look very

to MusicBean.java

fact
the

the bean only be created once at the first method call and persistfor the

Was this issue ever resolved ? We are running into the same problem.
The last response is "I'm not qualified to answer your EJB control question."

EJB injection not working for a Jersey class

I have a standard EJB3.0 bean defined as follows:
@Stateless
@Local(CustomerService.class)
public class CustomerBean implements CustomerService
I can successfully reference that EJB using dependency injection from a servlet with the following code:
public class CustomerServlet extends HttpServlet {
@EJB(beanName="CustomerBean")
private CustomerService customerService;
public void doGet(...) {
CustomerVO customer = customerService.getCustomerById(id);
However the same code will not work from a Jersey RESTful service class
@Path("/{customer}")
public class CustomerREST {
@EJB(beanName="CustomerBean")
private CustomerService customerService;
@GET
@Produces("text/plain")
public String getCustomer(@PathParam("customer") String customerId) {
CustomerVO customer = customerService.getCustomerById(customerId);
The Jersey RESTful service class will get executed but throws a NullPointerException because the customerService entity is null.
The CustomerServlet and the CustomerREST classes are both in the same WebApp, inside an EAR with the EJB.
They are even in the same package!
I would appreciate any help.

Congratulations. You've hit the major limitation of JEE-based dependency injection. You can only inject resources into servlets, filters, listeners, and tag handlers. This is why people eventually move to Spring if they really need dependency injection in non-JEE components.
You can read the WebLogic manual pages related to this at [http://download.oracle.com/docs/cd/E12840_01/wls/docs103/pdf/webapp.pdf] . Read chapter 8, "WebLogic Annotation for Web Components".

Edited by: vinaysb on Sep 1, 2010 3:29 AM

there is not much help to give. Java already says what the problem is: the cart/util/BookException class is not on the application's classpath. That can indicate a missing library or bad deployment settings. Hard to say what it exactly is.
All I can say is: learn how a JEE application is properly packaged and deployed and with that knowledge try and figure out where the mistake is.

@EJB not working when used in Cactus ServletTestCase

Hi All,
I am running my tests using Cactus ServletTestCase servlet and testing my EJB from there. I deploy my EAR application (my test servlet is in WAR, EJB in EAR modul)
When I run the test, I got NPE as the @EJB is not working and EJB ref is not initialized. Strange thing is, the @EJB is working fine from any other servlet or POJO in WAR.
Test result:

I am stucked with this one, dont want to use the EJB2 way with JNDI look up. Any suggestions much appreciated!

Was anyone ever able to figure out a solution for this issue? I'm having the exact same problem right now and this is the only reference to it I've been able to find online.
Thanks!

EJB 3 CMP not working in JBoss

hi,
i created a simple CMP Entity Bean with mySQL and works fine with OC4J but when delpoy to JBoss 4.0.4RC1, it doesn't work.
What I realised is that when a JDeveloper create a CMP Entity Bean from a Table it uses @Resource annotaion while I saw all the JBoss samples using @Persistance annotation.
I changed my CMP to use @persistence annotation and created a persistence.xml file; for somereason it is not working neither in JBoss nor does it work in OC4J.
Now, if i continue using @Resource annotation, where can I set the datasource so that the @Resource annotation uses my datasource when I deploy it to JBoss?
or is there any other way to get it working?
p/s: my datasource is working fine. i created a simple slsb and used
DataSource ds =
(DataSource)context.lookup(
"java:jdbc/mysqlDS");
and it works fine both in OC4J and JBoss
any help is appreciated.
thanks

Ok, i got this working in JBoss.
1) Replaced @Resource annotation with @Peristence annotation
@PersistenceContext(unitName="mysql")
2) Created persistence.xml in META-INF directory
<persistence>
<persistence-unit name="mysql">
<jta-data-source>java:/jdbc/mysqlDS</jta-data-source>

</persistence-unit>
</persistence>
that is it.
It means that whether we create EJB 3 on toplink EJB 3 or hibernate EJB 3, we should be able to run it on any of these as long as we stick with the standard annotations. JBoss Hibernate EJB has many additional annotations.
Now, the only thing that is not working is my Firebird DataSource in JBoss. If anyone has done it please let me know .. thanks.

The cisco snmp oids do not work, I can't get cpu or memory data.

Hello. I want to monitor the cpu and memory usages on my cisco devices using snmp. I found the snmp oids related to cpu in the following page :
http://www.cisco.com/en/US/tech/tk648/tk362/technologies_tech_note09186a0080094a94.shtml
I just copy the table here:
But the oids in the table do not work on my devices. For example, I have a cisco 3550 switch with the ip 192.168.1.211, version 12.2(25)when I want to get the informations about the oids up in the table, I got these results:
It shows that the oids cisco given up in the table are not existed in my 3550 switch's MIB. More weird is that when i add a number "1" to
the end of the oid cisco given, I can get some meaningless data for some unkonwn item names like "entreprises.x.x".
For most mib items, the snmp oids work well on my switch. For example, the following graph shows the interface out rate of the swtich:
I think the essence is when I executed the following command:
in all the output results, there's not any item relevant with "cpu" or "memory", but most other items are ok, such as interfaces, as shown below:
IF-MIB::ifDescr.47 = STRING: FastEthernet0/39
IF-MIB::ifDescr.48 = STRING: FastEthernet0/40
IF-MIB::ifDescr.49 = STRING: GigabitEthernet0/1
IF-MIB::ifDescr.50 = STRING: GigabitEthernet0/2
IF-MIB::ifDescr.51 = STRING: Null0
IF-MIB::ifDescr.52 = STRING: Vlan1
IF-MIB::ifType.1 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.2 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.3 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.4 = INTEGER: ethernetCsmacd(6)
IF-MIB::ifType.5 = INTEGER: ethernetCsmacd(6)
So why the cisco given oids won't work on my cisco switch, and how can I get the datas I want? Anyone has some advices? Thanks in advance!
In case the pictures I inserted missing, I attach my problem in the doc.

CDI not working in Weblogic 12c Embedded EJB Container?

Hi,
we are trying to use embedded ejb container from weblogic 12c (12.1.2.0) for our junit tests.
As our application is running in weblogic 12c, we would like to run our tests in same environment.
But we encountered two problems, which brings me to the conclusion that CDI is not working correctly in embedded ejb container.
1. CDI Interceptor are not working
2. CDI Objects (@Inject) are null
I can provide an error message, which I think is thrown, when container tries to access the interceptor, because if I delete the interceptors the error message gets no longer thrown:
Caused by: java.lang.UnsupportedOperationException: authenticatedLookup is unavailable for BasicNamingNode types
      at weblogic.rmi.internal.ServerRequest.sendReceive(ServerRequest.java:234)
      at weblogic.rmi.cluster.ClusterableRemoteRef.invoke(ClusterableRemoteRef.java:463)
      at weblogic.rmi.cluster.ClusterableRemoteRef.invoke(ClusterableRemoteRef.java:274)

      at weblogic.jndi.internal.WLContextImpl.lookup(WLContextImpl.java:483)
We just want to know, if CDI is not working in embedded ejb container, so we can go ahead and look for another solution for our junit tests.

Basic auth interop problem, servlet WS works, EJB WS not (Sun AS 8)

After spending some time I managed to add HTTP basic auth to a simple web service. I have implemented two variants, an JAX-RPC servlet web service and an EJB web service.
A (Sun) JAX-RPC client works pretty well against both web services. I do the required steps with the stub (set user/pwd) and things work. I do get the correct principal in the server side, fine.
When I do NOT set the authentication properties at the stub, the servlet based WS responds something like HTTP error 403 (?) or so, which leads to "authentication required". The EJB based response is not that adequate, it's something like "internal server error, EJBLocalAccessException or so" but from the given message you could get the idea what's wrong.
Anyway, I got the impression that this stuff
return HTTP error to flag "auth required"
is not happening for some reason in my EJB based web service. I found this problem in Sun AS 8 and I think it's the same problem when I test stuff with Oracle's OC4J ...
Some client implementations have obviously problems to get the idea that user authentication is required. In other words, the clients cannot invoke the EJB WS. I tried it with Perl Soap::Lite, MS SOAP Toolkit 3.0 and MS .Net 1.1 stuff. All this clients work well (with authentication) when I consume the servlet based web service. But the EJB based web service is not working at all. I do get there just "not allowed" and the SOAP client runtime is not handing over any user credentials (because it's obviously not correctly asked for it by an appropriate AS response).
Anyone else experienced this problems with EJB WS???
Interesting question: why is the JAX-RPC client working? Is it sending the properties set at the stub in any case? Or do they "handle" the internal error coming from Sun AS explicitly or so? Strange, in a way. :-)
Thanx for any help here!
Merten

I guess the reason was that I wrote
<login-config>
<auth-method>Basic</auth-method>
</login-config>
instead of required
<login-config>
<auth-method>BASIC</auth-method>
</login-config>
At deploy time, I got no error message. At usage time, I just got this AccessLocalException. That's not really nice ...

@EJB not working for managed beans in adfc-config

using adf 11.1.1.3
We have an application that uses EJB (deployed on the same WLS as our application). We notice that when we create managed beans in the adfc-config and use the @EJB annotation to get an instance of the sessionbean, it is not working.
The error we get is a simple nullPointerexception pointing to the EJB.
When we register the bean in faces-config.xml instead of adfc-config.xml, we do get an instance of the EJB.
I also get a nullpointerException when i add the managed bean to a taskflow instead of the adfc-config.
This is an example of the bean:
public class HomeTest {
    @EJB
    MyService service;
    public HomeTest() {
    public List getData(){
      return service.getSomedata();
}When i register this bean in adfc-config i get a nullpointer on service.
When i register the same bean in the faces-config, it is working.

Frank,
Thanks! I think i managed to implement the workaround:
This is my bean that has been registered in the faces-config:
public class BeanHelper {
    @EJB
    private MyEJB myEjB;
    public BeanHelper() {
        super();
    public MyEJB getMyEJB()
          return myEJB;
}In my adfc managed bean i use
MyEJB myEJB = (MyEJB)JSFUtils.get("#{BeanHelper.myEJB}");This is working fine.
This way i no longer need to use a direct lookup and i don't need to know the exact path and so on for the EJB.
Thanks Frank!
Is there a way to let Oracle update the bug with this workaround so if other people find the bug, they know how to implement a workaround?

@EJB annotation in JSF managed beans not working

Hi all,
I've been trying to get the @EJB annotation to work in a JSF manged bean without success.
The EJB interface is extremely simple:
package model;
import javax.ejb.Local;
@Local
public interface myEJBLocal {
String getHelloWorld();
void setHelloWorld(String helloWorld);
and the bean code is simply:
package model;
import javax.ejb.Stateless;
@Stateless
public class myEJBBean implements myEJBLocal {
public String helloWorld;
public myEJBBean() {
setHelloWorld("Hello World from myEJBBean!");
public String getHelloWorld() {
return helloWorld;
public void setHelloWorld(String helloWorld) {
this.helloWorld = helloWorld;
When I try to use the above EJB in a managed bean, I only get a NullPointerException when oc4j tries to instantiate my managed bean. The managed bean looks like:
package view.backing;
import javax.ejb.EJB;
import model.myEJBLocal;
import model.myEJBBean;
public class Hello {
@EJB
private static myEJBLocal myBean;
private String helloWorld;
private String helloWorldFromBean;
public Hello() {
helloWorld = "Hello from view.backing.Hello!";
helloWorldFromBean = myBean.getHelloWorld();
public String getHelloWorld() {
return helloWorld;
public void setHelloWorld(String helloWorld) {
this.helloWorld = helloWorld;
public String getHelloWorldFromBean() {
return helloWorldFromBean;
Am I missing something fundamentally here? Aren't you supposed to be able to use an EJB from a JSF managed bean?
Thanks,
Erik

Well, the more I research this issue, the more confused I get. There have been a couple of threads discussing this already, and in this one Debu Panda states that:
"Support of injection in JSF managed bean is part of JSF 1.1 and OC4J 10.1.3.1 does not support JSF 1.1"
10.1.3.1 Looking up a session EJB with DI from the Web tier
But if you look in the release notes for Oracle Application Server 10g R3, it is explicitly stated that JSF 1.1. is supported. So I'm not sure what to believe.
I've also tried changing the version in web.xml as described here:
http://forums.java.net/jive/thread.jspa?threadID=2117
but that didn't help either.
I've filed a SR on Metalink for this, but haven't got any response yet.
Regards,
Erik

@EJB annotation in entity bean does not work

I just started with ejb3. I have created a couple of beans. One session bean that looks like this:
@Stateless
public class MySessionBean implements MySession
     @Resource(name="jdbc/mydb")
     private DataSource myDB;
public void someMethod() {
myDB.getConnection()
This works great. The other bean is an entity bean, and there the resource injection doesn't work. It looks like this:
@Entity
public class MyEntityBean
@Resource(name="jdbc/mydb")
     private DataSource myDB;
public void someMethod() {
myDB.getConnection()
Is resource injection any different in an entity bean then in a session bean? Both beans belong to the same package and are in the same application, (ear). I have exactly the same problem with @EJB injection: it works fine in the session bean but not in the entity bean...
Any help is appreciated...
