Ejb-ql - important

The ejb-ql in the ejb-jar.xml
select object(d) from Dept d, IN (d.employees) e where e.ename = ?1
produces the following SQL after deployment.

which has 2 fields which are wrong. Namely Emp_empno and Dept_deptno . It should have been empno and deptno. Because of which I am getting invalid column names exception.
Can some one help?

Jeff,
Thanks for the reply.
The tables seen are specified by my self.
But, now I have got a solution. I have overridden the "finder-method"s query option with my own query. Since the container seems to generate the query wrongly when I go for more than one table. If I over ride the finder-method with my own query, then it goes on successfully.

Javax.ejb,CreateException import not found

I've upgraded from WL 8.1 to 10.3 and have an error "javax.ejb,CreateException import not found". javax.ejb used to be in weblogic.jar in 8.1 however, this path is empty in the version from 10.3. Where did it go? Do I need a new lib added to my build path?

javax.ejb.* is in j2ee.jar
if you use weblogic6.0, you need download ejb20.jar from http://www.weblogic.com
if you use weblogic6.1 ,you need't this file.

Importing EJB Model in NWDS

Hi, 
There is a simple Stateless Session Bean which uses an external library (JAR); and there is only 1 business method with just 1 line of code:
RecordEx r = null;
 
RecordEx is one of the library classes; 
While trying to import this as an EJB Model in Web Dynpro DC in NWDS (7.1 EHP1 SP01 Preview Version), it fails with a NoClassDefFoundError; 
Below are the steps followed; 
1. Create an External Library DC "ext" 
 1.1 Add the third party library to this DC 
 1.2 Create public parts ppC (Compilation) & ppA (Assembly) and add the library to both of these 
 1.3 Build the DC 
2. Create an Enterprise Application DC "util" 
 2.1 Add Buildtime dependency to ppA public part of "ext" DC 
 2.2 Build & deploy 
3. Create EJB Module DC "ejb" 
 3.1 Add Buildtime dependency to ppC public part of "ext" DC 
 3.2 Create a Session Bean (Stateless - Transaction: Container - Local Interface) 
 3.3 Create 1 business method, and create an object of one of the library classes in it 
 3.4 Add the business method to Local Interface 
 3.5 Check Component Properties > Permissions > Entity Forwarding 
 3.6 Build the DC - there are no build errors; default client & ejbjar public parts are created; 
4. Create an Enterprise Application DC "app" 
 4.1 Add the "ejb" as Referenced Project 
 4.2 Add "util" as Used DC with Deploy Time & Runtime dependencies; (informs "util" EAR DC has no public parts) 
 4.3 Create a Compilation public part "EjbClasses" > Reference Entities > Select client public part of "ejb" DC 
 4.4 Build & Deploy the DC 
5. Create a Web Dynpro DC "wd" 
 5.1 Add dependency to the "app" EAR DC 
 5.2 Add Buildtime dependency to ppC public part of "ext" DC 
 5.3 Add "util" as Used DC with Deploy Time & Runtime dependencies; 
 5.4 Import EJB Model Wizard > Select "app" EAR > Display 1 business method 
 5.5 But when that method is selected & click Next, nothing happens in NWDS. The Wizard windows stays like that with no processing 
And the NWDS log has this NoClassDefFoundError: 
 
!MESSAGE Unhandled event loop exception

informs "util" EAR DC has no public parts
this is probably the issue. see if you can make the external library show up in the public part of the util DC

Import javax.ejb cannot be resolved

Hi,
There are some libraries missing in the following code.
package era.budget;
import javax.ejb.*;
import era.budget.BudgetVO;
public class BudgetItemVO implements java.io.Serializable
     private Integer itemId;
     private BudgetVO budget;
     private int type;
     private String itemDetails;
     private int amount;
// -------------- BEGIN GET/SET METHODS --------------
public BudgetItemVO(Integer id)
          this.itemId = id;
     public BudgetItemVO()
     public Integer getItemId()
          return itemId;
public BudgetVO getBudget()
          return budget;
     public void setBudget(BudgetVO budget)
          this.budget=budget;
public int getType()
          return type;
     public void setType(int id)
     this.type=id;
public String getItemDetails()
          return this.itemDetails;
public void setItemDetails(String details)
          this.itemDetails=details;
public int getAmount()
          return this.amount;
public void setAmount(int amount)
this.amount=amount;
As aresult of these missing libraries there are some compilation errors..Some of the errors are as follows
     1)The import javax.ejb cannot be resolved
     2)EntityBean cannot be resolved to a type
3)EntityContext cannot be resolved to a type
4)EJBLocalObject cannot be resolved to a type
Thanx & Regards

Error in deploying a simple EJB 3.0

Hi ,
I am getting the following error while deploying my simple ejb of version 3.0 in Weblogic 9.2.
Exception preparing module: EJBModule(build) [EJB:011023]An error occurred while reading the deployment descriptor. The error was: Error processing annotations: java.lang.NullPointerException.
During my evaluation of Weblogic 9.2 for EJB 3.0 , I have got the following questions.
EJB Specification states that EJB's in EJB 3.0 can be developed and deployed without the need of deployment descriptors. I have created a simple EJB with two file Env.java and EnvBean.java and the source code is given below.
a) I just complied these class files and when I was trying to deploy without ejb-jar.xml and weblogic-ejb-jar.xml, the console was not at all allowing me to deploy.Why is this so?
b) After I created a META-INF file under root of classes directory by placing ejb-jar.xml with empty <enterprise-beans> element, console was allowing me to deploy with errors in parsing ejb-jar.xml. The error was either session/entity/mdb is a required under <enterprise-beans> element. Why is this required when there are several examples stating <enterprise-beans> element can be empty.
c) Later I updated ejb-jar.xml with <session> element under <enterprise-beans> with the following values. I got the above error when deployed with this change.
I had been struggling to deploy this simple bean for almost a day.Pleas point me if there is any documentation that solves my stated problem or if there is a solution.Thanks in advance.
regards
Karim

Presumably you're using the EJB3 tech preview, and not a vanilla WebLogic 9.2 install, right?
Can you post the full stack trace?

PHP using soap to call EJB

Hello everybody,
I've a problem to call a EJB form a PHP script.
There is a Apache with PHP 5.2.0 and a SAP NetWeaver Application Server 7.10 / AS Java 7.10 running on the system.
I wanted to use soap to call a method in an EJB. It's only a test EJB:
[code]
package beans;
import javax.ejb.Stateless;
import javax.jws.WebService;
import javax.jws.WebMethod;
@WebService(name="HelloWorldEARBean",serviceName="HelloWorldEARBeanService",targetNamespace="http://beans/",portName="HelloWorldEARBeanPort") @Stateless public class HelloWorldEARBean {
@WebMethod public String sayHello(String testStr){
 return "Hello Mr. "+testStr;
@WebMethod public String getReturn(String inputStr){
 return "the return value is"+inputStr;
[/code]
I tried it with the PEAR SOAP in the following script:
[code]
<?php
require_once 'SOAP/Client.php';
$wsdl_url = 'http://localhost:50000/HelloWorldEARBeanService/HelloWorldEARBean?wsdl';
$WSDL = new SOAP_WSDL($wsdl_url);
$client = $WSDL->getProxy();
$client->__trace(1);
$options=array('namespace' => 'http://beans/',
'style' => 'rpc',
'soapaction' => 'sayHello');
$NAME = "Bob";
$parameters=array(
 'parameters', $NAME
$result = $client->getReturn($parameters);
echo "<pre>";
print_r($params);
echo "</pre>";
echo "<h2>return</h2>";
echo "<pre>";
print_r($result);
echo "</pre>";
echo '<h2>Request</h2>';
echo '<pre>' . htmlspecialchars($client->__getlastrequest(), ENT_QUOTES) . '</pre>';
echo '<h2>Response</h2>';
echo '<pre>' . htmlspecialchars($client->__getlastresponse(), ENT_QUOTES). '</pre>';
?>
[/code]
The AS distributes the following WSDL:
[code]

[/code]
By the following output it's obvious that the AS or the EJB (webservice) doesn't receive the parameter send by the PHP script. Look at the output:

I used different soap interfaces for PHP like nusoap and the integrated soap interface of PHP 5.
Further I experimented with different parameters inside the function call
that results in small differencies at the xml-request.
Thanks.

Hi
I've solved the problem now. I just have to add
@SOAPBinding(style=SOAPBinding.Style.RPC)
in the EJB, that's all.
Here is the complete code, ... maybe some other guys have this problem too, so I will post the working code:
At first the EJB:
package beans;
import javax.ejb.Stateless;
import javax.jws.WebParam;
import javax.jws.WebService;
import javax.jws.WebMethod;
import javax.jws.soap.SOAPBinding;
import beans.HelloWorldEARBean;
@WebService(name="HelloWorldEARBean",serviceName="HelloWorldEARBeanService",targetNamespace="http://beans/",portName="HelloWorldEARBeanPort")
@SOAPBinding(style=SOAPBinding.Style.RPC)
@Stateless public class HelloWorldEARBean {
 @WebMethod public String sayHello(@WebParam(name="testStr") String testStr){
 return "Hello Mr. "+testStr;
2. the local XML:

Any body please help me how to call this web sevices method in J2ME client using kxmlrpc, i tried but it shows execption. And i want to know which url i want ot give inthe XmlRpcclient() and what are all the parameters to be given in xmlrpcclient.execute().

Is it a remote lookup? Then maybe this will help:

Looks like you are running a standalone java client, as opposed to JavaEE application client. You may find helpful info in Glassfish EJB FAQ:

EJB 3.0 entity found within JDeveloper but not on OAS 10.1.3

I'm tearing my hair out with this!
Basically I have an entity bean with a primary key annotated with @Id, a stateful session bean facade which has an EntityManager injected through @Resource, and a java client in JDeveloper which calls this bean through a lookup.
In JDeveloper 10.1.3 it works fine, no problems. I deploy the app, along with a JSP version of this client, to Oracle AS 10.1.3.0 - the deploy goes through without a problem. Whenever I try to use the JSP to test that it's working, I get a NPE in the server logs - but it only points to the compiled JSP class, and therefore not corresponding to a line in the actual JSP!
Here is the error stack trace:

Does this look obvious to anyone? All I am asking is a general idea to what the problem might be. I have been looking at this for 2 weeks and keep going round in circles. If anyone here has any idea that would be much appreciated.
I will supply other code (JSP, bean) if necessary, as this isn't a Java forum ;)
Thanks in advance

the problem is in your client code. you are instantiating the EJB locally. that is not what you want. you should be looking up the remote ejb using a Context object. look for information on setting up a client program to contact jboss using jndi.

I have not modified any .xml files, I don't recall the tutorial saying I have to.
I'm using Eclipse 3.2 WTP and it doesn't recognize that I have any Session beans... not 100% sure that EJB 3.0 is supported by it. I ended up creating a basic Java project to store the beans because an EJB project was saying that I need at least one bean.
Thank you in advance for suggestions.

While looking up why don't you use the fully
qualified jndi name"java:/comp/ejb...."?
What's the benefit of that?It's portable. Any direct access of a global JNDI namespace is not portable.
Also, it's "java:comp/env", not "java:/comp/env".
>
Is it possible to use annotations in JSPs?No, annotations are not supported in JSPs for Java EE 5. In the web tier
they can be used in certain managed classes such as servlets.
Regarding your original posting, how exactly did you deploy the ejb? If you
got a message saying the ejb-jar had no ejbs, that sounds like the root of
the problem. If the ejb-jar only contains a single EJB 3.0 bean and that
bean uses EJB 3.0 annotations instead of a deployment descriptor, make
sure there is no ejb-jar.xml. It's possible that Eclipse packaged an
EJB 2.1 - based ejb-jar.xml descriptor inside the ejb-jar. In that case,
the app server will assume it is an EJB 2.1 app and not process any
annotations.

EJb 3.0 com.ibm.mq.jms.MQQueueConnectionFactory

Hi All
I see this error
[EJB:011013]The Message-Driven EJB attempted to connect to the JMS connection fa
ctory with the JNDI name:xxxx.ccerqcf. However, the object with th
e JNDI name xxxx.ccerqcf is not a JMS connection factory. NestedEx
ception Message is :com.ibm.mq.jms.MQQueueConnectionFactory
When using MDB/ EJB 3.0 in WLS 10.0 Mp2
When I use EJB 2.x I don't see the issue, can ejb 3.o read weblogic-ejb-jar.xml for its connection factory?
Is there any debug flag to see a better exception
This is a MDB intended to listen to message from IBM MQ server using a foreign server configured in the console
