Statful Session bean and its life
Hi,
I don't know how long a Stateful session bean lives in the memory. What keeps
the stateful bean around?
I do have a Stateful session bean in my application creating some problem. When
the user first uses the stateful session bean, the bean remote reference is stored
in the user session object. Even though the user session is active and not invalidated,
stateful session bean is getting timed-out. I am using weblogic 6.1 with SP2.
Please help. Thanks.
Below is the exception stack trace:

The usual cause is a user loads a page, the request takes a while so
they hit stop and reload. There's other possibilities like frames etc.

Thanks Rob for the response. Every instance of the sfsb is tied to a particular
user web session. I am not sure how the concurrent calls take place. I am almost
certain that I am not calling any methods in sfsb concurrently. Thanks again.

The sfsb hasn't timed out. This is the EJB lock manager that's
complaining. I suspect you are trying to make concurrent calls on a
sfsb instance.

RPC web service session beans and local interfaces
I am wondering if it is possible to use EJB 2.0's local
interface (vs remote interface) with 6.1's RPC web service
session beans. Since WLS generates the SOAP servlet that
invokes the RPC session bean and I do not find
a way to some how tell SOAP servlet to use local interface to
get the session bean's local home interface, I am not sure
this can be done.
Any comments would be appreciated.
Thanks.
PeterTa. Thanks for the info.
Any idea when Local I/F support is due?

I was just about to post the very same question - but for WLS 7.0.0.1.
There are essentially two questions:
1) (from a functional perspective)
Can I expose Local Interfaces as SOAP using the auto-generation(servicegen ant
tasks)?Local Interfaces support is coming.
2) (from a performance perspective)
Does the generated SOAP implementation go via the (expensive) RemoteInterface
(ie marshalling) - or is the RMI marshalling optimised out (by setting<enable-call-by-reference>true</>)?
You can set this option by yourself on your EJB. Web service runtime
doesn't
do any magic in this area.

Nick

Stateless session beans and idle timeouts (weblogic 10.3.1)
Need clarification about stateless session beans and the idle-timeout-seconds setting.
Situation is this – we have a process that is timing out due to an API call to a very slow Authentication server.
I am trying to resolve this with a code change, but need to further other understand what the server is actually doing.
We have a session bean which calls another which is calling a util class that does all the work and returns the results back up to the initial session bean. I have left out the ejbName in these examples (it’s irrelevant here).
Example:
SessionBean1 // basically called just once a day
@Session(defaultTransaction = Constants.TransactionAttribute.SUPPORTS,
enableCallByReference = Constants.Bool.TRUE,
type = Session.SessionType.STATELESS,
transTimeoutSeconds = "0",
initialBeansInFreePool = "0",
maxBeansInFreePool = "20")
Methods
@RemoteMethod() public boolean getUserList(String adminGroup) {
Map usrList = getUserList(adminGroup);
Private Map getUserList(String adminGroup) {
return SessionBean2.getUsers(adminGroup);
SessonBean2
@Session(defaultTransaction = Constants.TransactionAttribute.SUPPORTS,
enableCallByReference = Constants.Bool.TRUE,
type = Session.SessionType.STATELESS,
transTimeoutSeconds = "0",
initialBeansInFreePool = "3",
maxBeansInFreePool = "20")
Method
@RemoteMethod() public Map getUsers(String adminGroup) throws RemoteException {
return javaUtilClass.getUsers(adminGroup);
JavaUtilClass
Method
public Map getUsers(String adminGroup) throws RemoteException {
// This is where the work happens, calling the Authentication server to get a complete
// list of users for an admin group. When the user list is around 1500 entries, this can
// take an hour. Did I mention this server is very slow? It’s about this threshold of 1500
// that causes the timeout.
return Map of users
First thought, just bump the idle-timeout-seconds setting for the session beans (from the default 600), but that would be a temporary solution until the user list grew larger.
Second thought, refactor the call to the Authentication Server API to get the user list in blocks of data (say 400 at a time) and decreasing the call/response time between the method getUsers and the API call. This would still occur in the JavaUtilClass, so I am unsure this would make a difference. The session beans would still be idle and subject to timeout, correct?
Would setting initialBeansInFreePool to 1 in SessionBean1 make any difference?
Or should I be looking at replicating the re-factored method from the JavaUtilClass in SessionBean1 where the user list is being used so that the API calls come back to it and keep it 'active'?
Thanks for any advice you could give me on this.Hi
regarding timeouts, there are two ways:
1.- Changing the settings in the JTA WebLogic domain , called "Timeout Seconds". This will affect globally to all EJB deployed in the domain.
or
2.- Specified directly in the bean with a weblogic annotation, like this:
@TransactionTimeoutSeconds(value = 300)I hope this will help you.
Regards.

ThomasIt means the pool doesn't have a connection available for this thread to use, after waiting
some time for any other thread to return one. Either your pool is not big enough, or your
bean code may sometimes be forgetting to close any connection it gets. Note that in
a stateful session bean, you may fall into the trap of retaining a JDBC connection open
for the duration of the session. If you do this, your pool must have as many connections
as the maximum number of simultaenous sessions you want to support. Usually the aim is
to obtain a pool connection, use it, and return it to the pool, all within any single response
to the client. Then you only need as many pool connections as there are execute threads
in the server. Having a DBMS transaction that spans user input is an invitation to deadlocks,
bottlenecks in performance etc.

Stateful session bean and faces
I have one stateful session bean(EJB) that manages business logic and conditional page flow. In the web part i have a bunch of JSP pages and each page has it's own JSF bean with data and "submit" methods. Each bean has to keep a reference to this stateful bean and it should be the same reference among all beans. Also i have to create and destroy this bean some way (I think i can use HttpSessionBindingListener).So, any suggestions how to do this? Also i'm searching for 'tips'n'tricks' or design pattern for JSF.
antonwhy do you need to hold the same EJB reference in all your JSF beans?
something is wrong with your design, you should take a closer look to see why you need this. a stateless bean does not hold client specific state and there is no difference between stateless bean instances, so your JSF beans do not have to point to the same EJB reference. -
Session Beans and TIBCO E4JMS and Weblogic JMS 8.1
Setup:-
Weblogic Server 8.1 SP2 on Linux
TIBCO E4JMS 3.1.2
I have a two Staeless Session Beans which are deployed in both sides of the cluster
- Cluster is made up of two servers(ManagedServer1 and ManagedServer2) on the
same machine. The beans have container managed transaction and trans-type set
to required. The JMS Server is on ManagedServer1. The session bean publishes 100
messages to TIBCO JMS and Weblogic JMS and calls the second bean which again publishes
100 messages to TIBCO JMS and Weblogic JMS .
The connection factories used are XAQueueConnectionFactories.
This seems to work under the following conditions:-
a) The session beans are deployed just in ManagedServer1
b) The WL load balancing scheme manages to run both the beans on ManagedServer1
c) If I don't publish onto Weblogic JMS( It runs successfully on ManagedServer1
and ManagedServer2)
It does not seems to work :-
When the The WL load balancing scheme manages to run both the beans on ManagedServer2.I
put debug statements on the beans and it seems to publish everything but fails
during the commit

Apologies in advance if this need to be posted in the JTA news group..
Any ideas?
Murali
Posting to the transaction newsgroup would probably also be helpful.
Can you post the code for the session bean so we can see how you're
enlisting Tibco in the transaction? It looks like you're using the JMS
provider wrappers from 8.1, which do the transaction enlistment for you, so
you shouldn't need to mess with JTA at all in your code. Still, something
weird is going on and it'd be nice to see exactly what your code looks like.

Statefull session bean and MDB architecture
Hello members,
I'm planning to design an application in the following manner but not sure if that's the best design. Your input would be greatly appreciated.
I have a stateful session bean (is also a MessageListener) which takes an order, sends the order to a MDB (which processes it by saving it to database and returns some search results). Then the MDB sends the search results as a message back to the stateful session bean.
This seems to work fine, but I'm not sure whether I'm violating any of the J2EE specs.
Thanks for your response,
-athanks.
the reason i was asking these questions was i was playing with a stateless session bean that displays a jframe. i download from a jsp, and then close the browser, the jframe continues to function. i have not gotton deeper into functionality yet but i wonder if this poses a security problem: can this frame access the local computer system and do bad things? since it lives outside the browser, it appears dangerous.
another interesting thing is when i close the frame, it shuts down the app server, even when i set the jframe to do nothing on exit. can you shed some light on this? -
WebLogic 10.3.0, web-service enabled session beans, and CMT transactions
Does WebLogic 10.3 support CMT for JAX-WS Web-Service enabled EJB 3.0 session beans?
When a client invokes the following Web service:
@WebService
@Stateless
@TransactionManagement( TransactionManagementType.CONTAINER )
public class TestService
@WebMethod
@TransactionAttribute(TransactionAttributeType.REQUIRED)
public String echo( @WebParam( name = "param" ) final String param)
Context context = new InitialContext();
TransactionSynchronizationRegisttry registry =
(TransactionSynchronizationRegistry)
context.lookup( "java:comp/TransactionSynchronizationRegistry" );
registry.putResource("foo", "bar");
return param;
}WebLogic throws this exception:
SEVERE: Transaction does not exist
java.lang.IllegalStateException: Transaction does not exist
at weblogic.transaction.internal.TransactionManagerImpl.putResource(TransactionManagerImpl.java:2033)
at weblogic.transaction.internal.TransactionManagerImpl.putResource(TransactionManagerImpl.java:2029)Is this a bug in WL 10.3.0?
Thanks in advance.
Edited by: user572625 on Aug 18, 2011 12:29 AMThis is fixed now. Someone had defined a Servlet for the web service in web.xml that was preventing the EJB container to kick in.

Prerequisite boolean statement for SET and its value in ggb1
hi all,
i read in sap help and wonder where and how to create the set and assign the value to it. any advice is appreciated.
thanks
COBL-BLART IN DOCMNT-TYPE OR COBL-WAERS IN CURRENCY
This statement contains two sets: DOCMNT-TYPE and CURRENCY. The set DOCMNT-TYPE contains the values SA and SB; the set CURRENCY contains the currency codes DEM, SFR, LIT, BRF, and HFL. Both sets use dimensions from table COBL.
The combined statement is true if the document type is SA or SB, or the document's currency code is DEM, SFR, LIT, BRF, or HFL.hi,
sets are created in GS01
hope this helps

SQL SELECT statement Parent_child table and its related table..... HELP plz
I have 2 tables
Table Parent_child_table:

2 | 4 | 12 | vv
I want to select Name from parent table where selected child ID are in PRODUCT table.....
The result would like:

select
p.name
from Parent_child_table p
where p.parent_id is null
and exists
select
null
from Parent_child_table p1, products p2
where p1.id = p2. parent_child_table_id
and p1.parent_id = p.id
)The reason it's a guess is because you've really done nothing to outline WHY you should get the results you say you would like. The more time you spend creating a clear question, the less time you'll have to spend weeding through useless answers.

Share stateful session bean in JSF managed beans with different scope
Hi,
I have a JSF application and I want to try to use of stateful session beans.
So I created a new stateful session bean and its local interface.
@Stateful
public class StatefulSessionBean implements StatefulSessionBeanLocalInterface{
private String name;
@Local
public interface StatefulSessionBeanLocalInterface {
...In my JSF application I have a mananed bean with session context which registers the new interface by
this annotation
@EJB(name="sessionbeanref", beanInterface=StatefulSessionBeanLocalInterface.class) and set the name to something.
Now I want to fetch this name in another managed bean with request scope. So I looked up the bean and tried to get the name.
StatefulSessionBeanLocalInterface = (StatefulSessionBeanLocalInterface) new InitialContext().lookup("java:comp/env/sessionbeanref");
System.out.println(currentmailingbean.getName());but the name is null.
Why?The xsd was created via the netbeans J2EE enterprise application dialog and I think its the most recent.
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" 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/web-app_2_5.xsd">All other annotations seem to work.
Wouldnt the lookup completely fail if the deployment process thought that it is version 1.4 ? -
Creating and deploying ejb 3.0 session bean with annotated pojo
I try to create and deploy a EJB 3.0 stateless session bean (and associated webservice) with the following steps:
1) Create Interface "Repository"
package de.xxx.config;
import java.rmi.Remote;
import java.rmi.RemoteException;
import javax.jws.WebMethod;
import javax.jws.WebService;
@WebService
public interface Repository extends Remote {
@WebMethod(operationName = "findCampaignByChannel")
public String findCampaignByChannel(String channelName) throws RemoteException;
2) create dummy "RepositoryImpl"
package de.xxx.config;
import java.rmi.RemoteException;
import javax.ejb.Stateless;
import javax.jws.WebService;
@WebService(endpointInterface="de.xxx.config.Repository")
@Stateless
public class RepositoryImpl implements Repository {
public String findCampaignByChannel(String channelName) throws RemoteException {
return null;
3) The two class files are packaged into a jar without any further descriptors
4) The jar is deployed with admin_client into the oc4j instance using the commands:
-deploy -file <jarfile> -deploymentName <name>
Result:
An ear was constructed and started but no session bean or webservice is found (using the console). But according to to the docs a jar file without a ejb-jar.xml should be recognized as a EJB 3.0 ejb-jar file and the necessary steps to create session bean and expose webservice should be done automatically.
My question:
Which step do i miss here ?
Tools used:
Eclipse 3.2 for the jar file
SoaSuite 10.1.3.1 for oc4janother strange problem.
i have an APplication server added ( JBOSS ).
when i create deployment profile (EAR ) application server is showed in the ComboBox .
But when i create Java Test Client for some EJB and when i check " Connect Remote Application server" there is 2 comboboxes
J2EE Application
App Server Connection.
first combo is ok there is EJB applicaiton
Secound is empty .. but i Have App Server.
Another think is that when i create EJB 3.0 its BAD to see J2EE app it must be J EE 5 app or just Java EE app -
Losing UserTransaction state in Stateful session bean
I have a UserTransaction I wish to begin and commit in different methods of a Stateful session bean. I have 2 methods to test this on the session bean:
public void beginTransaction()
trans = context.getUserTransaction() ;
trans.begin() ;
public void commitTransaction()
trans = context.getUserTransaction() ;
trans.commit() ;
If I call these methods from one Perform method in a Struts action all works fine. If I call the methods in different Struts actions (storing the session bean handle on the HTTPSession in the first for retrieval in the second) the second call fails with the following exception:
java.lang.IllegalStateException: No active Transaction
The state of the transaction on the second call is STATUS_NO_TRANSACTION. I am certain that I have lost no state on the session bean and that using handles gives me the correct bean since I have written some state to test this. Basically something seems to close the transaction between the end of the first Perform method and the beginning of the second (I am of course assuming this is a valid thing to do).
My session bean descriptor has <transaction-type>Bean</transaction-type>, and I am using OC4J.
If anyone can point out what it is I am doing wrong I would be grateful!
James.Sorry, I have re-checked my code and I believe I found the problem.
I was beginning my transaction inside ejbCreate() and trying to commit/rollback in another method. This works in JBoss 3.2 but does not work in either OC4J or WebLogic 7.
If I begin my transaction in a business method and commit/rollback in another method, everything works fine. (It also seems to work fine in 9.0.3 this way).
So I am not sure whether this is a bug in 9iAS/WLS, or a bug in JBoss, or something that is left "vague" in the J2EE spec. Unfortunately, examples on bean-managed transactions are thin on the ground generally (the usual advice being not to use them, which I definitely agree with!).
If you believe that the behaviour I describe is a bug in 9iAS, I can send a simple EJB test case.

2 local ejb and one remote session bean in same server - java client
idea was -
to create a new stateless session bean that will talk to the two entity beans. although the session bean will expose its method through a remote interface, the communication betweenn the session bean and the entity beans will be through a local interface. the assumptions is that all three ejbs are running in the same JVM.
so -
all three ejbs complied properly.
but -
when i tried to test with one 'sample test client' then this is the error i get.
please please -

Process exited with exit code 0.After you drop an ejb into the designer, you'll see a <ejb>Client1 instance created for the ejb in the backing bean (i.e. Page1.java). The client instance is a wrapper for the ejb. It contains all the remote methods available on your ejb. In your web app, you can invoke any methods on the client instance as if you're calling methods on a regular java object. The wrapper class knows how to invoke the corresponding methods on the ejb for you.

HttpSession vs. Stateful Session Bean ---- when State Session is large
I hope most of the people come across with this issue where to put the state
for the internet/intranet based applications when they are using
servlet/jsps calling session beans. Weblogic 4.5.1 does support httpsession
in-memory replication for the servlets but the stateful session beans are
not replicated in clustered environment. Plus with stateful bean u get
activation/passivation overhead too. So one tempts to use stateless session
beans and store state in httpsession?
Then what is the upper limit for the session state one can put in
HttpSession with the weblogic? Is there any way to configure it?
One way to overcome the httpsession size limitation is to use database for
storing state and just store some unique Ids for the session info in
httpSession. But then there will be overhead for database connection?(jdbc
connection pool can provide some help here). So what is the recommended way
for doing this provided few thousand concurrent clients with session size
say exceeding 4kb per client?
Thanks
UsmaniThere are no special setting in sun-ejb-jar.xml regarding cache settings. The default settings from server.xml are used:

</ejb-container>The Session Bean uses Container Managed Transaction. Is it possible in this case, that the bean isn't 'idle enough' in order to set into passivated?
