Hi friends,
I need to call a ejb from second ejb ( entity bean from a sission bean). I have defined all xml mapping in ejb.xml.jar and server specific jar file (jboss.xml.jar). I am using boss-4.0.5.GA. But when I am calling that session bean from simple desk top client. It show me this error

Hi,
According to WAS 6 , every opened connection has to be commited (or rolledback) explicitly (didnt try autocommit) before closing. Even if all you have done with that connection is a SELECT Query.
This has apparently solved the same problem I was getting. implement it and see whether it helps you.

Error:Could not find binding for QNameProperty - in WLS 11g-Plz help!!
I have a WSDL containing complexType and simpleType. I generate the webservice from wsdl using JAX-RPC.
When i deploy it in WebLogic 11g I get the error: Could not find binding for QNameProperty substringType :
<xs:complexType name="SimpleTerm">
<xs:sequence>
<xs:element minOccurs="0" name="entityConstraint" type="xs:string"/>
*<xs:element minOccurs="0" name="substringType" type="S5:substringTypeSimpleTermEnum"/>*
</xs:sequence>
</xs:complexType>
<xs:simpleType name="substringTypeSimpleTermEnum">
<xs:restriction base="xs:string">
<xs:enumeration value="beginswith"/>
<xs:enumeration value="endswith"/>
</xs:restriction>
</xs:simpleType>
My Observations:*
If i remove the simpleType's i dont get any error.
If i generate webservice from the same wsdl using JAXWS then the project gets successfully deloyed in WLS11g.
Kindly help me in solving the problem using JAX-RPC.

Seems known issue. I would suggest to raise an Service Request with the test case.

JNDI Lookup for EJB3 (Bean to Bean)
Hi Forum,
i've search the whole internet and two books but I could not find an answer that pleased me.
I want to get a reference to an EJB3 by JNDI Lookup. With container managed dependency injection everything works fine but I have to do a little more generic way, thats why I want to work with JNDI Lookup.
I have the following situation:
At first I have a stateless bean
@Local
public interface Job {
* run the job
* @return true if the job executed without errors
public boolean run(SchedulerConfig schedulerConfig ,JobContext context);
@Local
public interface AConcreteJobLocal extends Job {
//no more declarations
@Stateless
@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
public class AConcreteJobBean implements AConcreteJobLocal {
//implemented methods goes here | removed for better overview in the post
} This is a typical declaration for a bunch of jobs I have. Every concrete job has it's own bean if it necessary in some way for you to know.
So now I wanted to write a bean which returns me an bean instance via a JNDI lookup
@Stateless
public class JobJNDILookupBean implements JobJNDILookupLocal {
Logger logger = Logger.getLogger(JobJNDILookupBean.class.getName());
public Job getJobBeanFromJNDIName(String jndiName) {
Job job = null;
try {
Context c = new InitialContext();
job = (Job) c.lookup("jndiName");
} catch (NamingException ex) {
Logger.getLogger(JobJNDILookupBean.class.getName()).log(Level.SEVERE, null, ex);
} catch (IllegalArgumentException ex) {
logger.log(Level.SEVERE, "Bean not found", ex);
return job;
}When I call this method I always get a NameNotFoundException

java:/comp/env/ejb/AConcreteJobLocal
java:/comp/env/ejb/AConcreteJobBean
java:/comp/env/AConcreteJob
java:/comp/env/full.package.and.Class.name
this all without java:/comp/env
etc.
The only way it worked was when I added a annotation to the JobJNDILookupBean in this way
@Stateless
*@EJB(name="ejb/AConcreteJob",beanInterface=A.Interface.location)*
public class JobJNDILookupBean implements JobJNDILookupLocal {
}But this is not what I want to do. Thats why my question. How can I lookup a bean without annotate it in the bean which want to look it up???
In other words whats wrong here
@Stateless
public class JobJNDILookupBean implements JobJNDILookupLocal {
Logger logger = Logger.getLogger(JobJNDILookupBean.class.getName());
public Job getJobBeanFromJNDIName(String someJndiName) {
Job job = null;
try {
Context c = new InitialContext();
job = (Job) c.lookup("someJndiName");
} catch (NamingException ex) {
Logger.getLogger(JobJNDILookupBean.class.getName()).log(Level.SEVERE, null, ex);
} catch (IllegalArgumentException ex) {
logger.log(Level.SEVERE, "Bean not found", ex);
return job;
}I hope you understand my question and more than this I hope some has the answer.Hi Zsom,
Zsom wrote:
One thing you need to keep in mind is that beans aren't instantiated every time you make a call to your EJB. You're right! But because the fact the beans are all stateless it doesn't matter. I don't want to get a new EJB at a lookup. If I get a reference to a bean which was used a million times before it is absolutely ok
Zsom wrote:
You might be gaining some time because the container can create new beans more quickly, but you are also looking up the beans before each call, which in the long run will be even more expensive.Mhm, I don't know if I understand you. Maybe I explain my process a little bit. I have a lot of different jobs in my application (JobDoThis, JobDoThat, JobFoo, JobBar). Every job has a own bean which keeps the business logic. Furthermore I have an job engine which is able to execute jobs which are configured to run and this engine can solve some dependencies (If JobFoo fails don't execute JobBar , and so on). When I build my engine I want to get a reference to a jobBean by jndi lookup which keeps the business logic and then call some method on it. This means that the lookup will only be called when I build a new engine. And because this doesn't happen so often performance is not so important. Furthermore if all jobs all configured to run the application needs sometimes more than 12 hours (depended from the amount of data) for one run (Start to End -> the application has a little script character), that's why performance as I said already is not so important.
Zsom wrote:
But it would be worth making some test, because to me it seems a bit like bad design.Yes it could be, but this was my first thought to instantiate a bean (or get a reference to an existing one) dynamically. I don't like this hard coded dependency injection. I mean it's great If you know at compiletime which beans you need. But because we don't know which beans we need it's a big overhead to inject them all by container and then use only 40 percent of the injected bean because for example only 40 of 100 jobs shall run.
If there is another approach to get a reference dynamically which is better than this then I will try, no problem, but unfortunally I don't see another. -
@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 / JNDI binding question (ColdFusion 9)
Hello,
I am running ColdFusion 9 (developer edition) on my local machine (Windows XP SP3; 2,66Ghz; 2Gb RAM) through / using IIS 5.1.
Using this environment I'm trying to implement the Belgian e-ID applet (hosted on Google code) authentication example. But for the authentication to work, the SDK pdf tells me to register an EJB in JNDI.The basic configuration (being adding servlet & servlet mapping sections in the web.xml configuration file) works for identification, but no results for authentication...
I already contacted the eID site admin(s), requesting additional information on how to achieve this, but this yielded no results as well, as they forwarded me to the vendor of my web server (ColdFusion).
To make a long story short, is it possible to provide me with an example on how to register this / an EJB for use with the technology mentioned above?
Thanks in advance!Well, your web server isn't really ColdFusion - if you just installed CF using the default settings, you're using JRun for both your web server and for the underlying J2EE container required by CF. So I'd recommend looking at the JRun documentation - just Google "jrun ejb".
The default location and availability of JRun components in a default install of CF is a bit different than it is with a full JRun install, so you might have to reinstall CF using the JRun option, which installs a full version of JRun and then installs CF as an individual JRun server instance.

Dreamweaver doesn't use the MySQL ODBC driver. It uses the PHP MySQL extension, which is not enabled by default in PHP.
The method of enabling the MySQL extension depends on how you installed PHP. However you can check whether it's enabled by running <?php phpinfo(); ?> in a PHP page. Scroll down the page of configuration details to see if MySQL is listed. -
WebLogic 10 and EJB 3.0 for Message Driven Bean

I am compiling and creating jar file for this class. Then I am creating a .ear file for this.
The meta-inf/application.xml contains the following:
<?xml version="1.0" encoding="UTF-8"?>

</application>
I don't want to use deployment descriptor (ejb-jar.xml or weblogic-ejb-jar-xml), because I want to utilize the annotation feature of EJB3.0
So, after creating the .ear file for this, and try to deploy on weblogic 10, I get the following error:
An error occurred during activation of changes, please see the log for details.
Exception preparing module: EJBModule(MDBWorking1.jar) Unable to deploy EJB: CalculatorBean from MDBWorking1.jar: [EJB:011113]Error: The Message Driven Bean 'CalculatorBean(Application: MDBWorking1, EJBComponent: MDBWorking1.jar)', does not have a message destination configured.

How to solve this?
Note:
I don't want to use Deployment Descriptor and all I want to use is EJB3.0's annotation feature.
Thanks,
GuruDear gurubbc,
I don't know if it still matters to you but you can use the javax.ejb.MessageDriven annotation to point your bean on your queue. I had the same issue like you but i could not solve it properly by switchihg to weblogic.ejb.MessageDriven.
Use the following annotation and it should work out:
@MessageDriven
(mappedName = "queue/mdb",
name = "CalculatorBean",
activationConfig = {
@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue")
Here you can see that the mappedName is the JNDI name of the queue you are trying to connect to. The name is the name for your Bean, and the only property passed is the destination type.
Hope this helps.
Cheers,

Do JNDI look up for entity beans from a session bean in different jars
I have a problem doing entity beans JNDI look up from a session bean which is deployed
as a separate package (session.jar) from the entity beans (entity.jar)
I believe if both session bean and entity beans are deployed into one jar and
I specify ejb-local-reference-description for session bean, it should work. However,
due to some reason, they have to be in separated packages but still in the same
container. Then question how to do JNDI lookup given entity beans only have local
interfaces?
FYI.
1 both session.jar and entity.jar are self-contained. i.e., no deployment error.
each JNDI name can be viewed from JNDI tree

xjc on the schema definitions I found at http://java.sun.com/xml/ns/j2ee/ but I can't get it to work. It produces reams of errors, see below for a short extract.
Of course, someone could put me out of my misery and tell me where to find a binding that someone else has done. I can't be the first chimp on the planet that has wanted to do this!
Any help much appreciated.

Problem with Action binding for a command button in a Managed Bean
Hi
Thank you for reading my post
I am trying to use a backing bean for a button action binding.
I followed all steps as they seems to be correct. i did not made any changes directly by hand , all of changes are introduced by oracle
Jdeveloper wizards. but now i get this exception
Managed bean is defined in faces-config.xml (it shows in preview mode) , the method is there in managed bean (Jdeveloper itself create the method i just enter its name)
can you please take a look and tell me what can be wrong?
thanks
here is method and its body in managed bean
public String userAccept_action() {
BindingContainer bindings = getBindings();
OperationBinding operationBinding =
bindings.getOperationBinding("Commit");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
return null;
}here is the exception that i recive

Specifying JNDI Details for Controls (EJB/JMS) in Workshop
Hello,
I was running into some basic issues in using workshop for building applications. Any help is appreciated !
How do I point Controls (EJB/JMS) to JNDI where the Objects have been bound
In J2EE I will do this :
Context ctx = new InitialContext(ht); // ht has Provider URL etc.
Specifically in Design view of Workshop for (WLI) JMS Control how do you define PROVIDER_URL, SECURITY_PRINCIPAL, etc. My JMS Server is targeted to separate Managed Server that where Workshop Applications are deployed and I do not want to create Foriegn Destinations etc. on Managed Server where Applications get deployed.
For EJB Controls: How do you lookup remote EJBs that get deployed as a part of (EARs) on managed server (different from where Workshop Application and EJB Controls reside)
Basic Question: How do we distribute this "EJB Control" JAR to clients to call these EJBs using controls and specify the JNDI Environment for the control that surfaces the EJB resource deployed remotely?
I cannot import these as modules in an Workshop Application (=> EAR) and generate controls from these as they will get "deployed" in that application and we want only one deployment.
Thanks
HarishHi there,
In your GUI client you should consdier building a model that represents the data that you want the GUI to display. This model would contain the references to the EJB's that you need to use. If you want to avoid using some kid of model then it really depends on the complexity of your GUI. If your GUI consists of one JFrame then everything can be done inside the main class for the GUI. If you have lots of sub windows then you need to consider where the references will be used. If theyare used in more than one window then you could end up with lots of complex cross references which is why the model would be better in this situation.
JNDI lookups can be expensive and this depends on several factors particularly network latency, if your client is self contained then once you have a reference to a home interface then you may as well keep and use it for any future calls. The key to this is keeping references to home interfaces as instance variables rather than scoping them locally.
There should really be no bottleneck caused by using as single session bean as a Facade to your EJB tier. The Session Facade is a very common pattern and the one that is most espoused by the various authors writing EJB tech books. As far as coupling is concerned this is an ideal situation as your client can then make coarse grained calls to the single facade session bean instead of making lots of smaller fine-grained calls to several session beans. I'd say that this is a good general design.
Hope this helps

Error while passing ODI variable in JNDI Url for JMS Queue XML
Hi,
Facing a weird problem while passing ODI variable in JNDI Url for JMS Queue XML.
Below is the JNDI Url configured under ODI Topology:
JNDI Url: t3://<host_location>?d=#TEST.SCHEMA_FILE&s=<schema_name>&JMS_DESTINATION=jms/<queue_name>
where,
#TEST.SCHEMA_FILE --> ODI variable storing xsd name and location
Issue Description:
If we restart ODI server then for the first run of any ODI interface using JMS Queue XML, it is unable to get the value for ODI variable present in JNDI Url (d=#TEST.SCHEMA_FILE).
It throws error message saying: No XSD found
Temporary Resolution:
As a temporary fix if we hard-code and pass the value in that ODI variable as shown below, it will successfully go through.
eg: JNDI Url: t3://<host_location>?d=C:\XSD\test.xsd&s=<schema_name>&JMS_DESTINATION=jms/<queue_name>
Reverting it back to variable later will have no issues and subsequent run will succeed.
But again anytime later if server is restarted then first run will have this issue.
Want to have permanent fix for it.
Any one having idea on it please share. Appreciate your help!What ODI version are you using? It could be related to the bug in the older version as described in support note Doc ID 1290326.1

Error in Event Binding for Table UI element
Hi,
I had created a table UI element in my web dynpro component and it worked fine. After a few weeks, while I was making some other changes in the same module and did a syntax check on the component, I got this error "The event binding for element "TBL_ABC" contains errors". There is a "Correct errors" button given along with this error message, which removes the error. But I just wanted to know what is the reason for this error.
Regards,
Akshatha.Hi,
Please check for the cardinality of the node which you are using to bind for the TABLE UI element.
I think the cardinality should be either 1:N or 0:N.
Give it a try.
