Session facade lookup fails occasionally

Hey all,
Since a few weeks we're having some problems with our weblogic server. We're running a number of ears and wars which communicate with each other using a BusinessDelegate and Session Facade. The InitialContext lookup which is done, suddenly seems to fail at random occasions (today I counted around 20 failed lookups of the facade of one application and > 800 succesful transactions.
is there anyone who has seen this behaviour before? I'm kindof running out of ideas. Maybe something with the garbage collector?
Caused by: javax.naming.NameNotFoundException: Unable
to resolve 'XXXFacadeBean' Resolved ; remaining
name 'XXXFacadeBean'Regards,

Ejb3 session bean lookup

Hello, I have following problem with the ejb3 and session bean lookup:
For example, I have a session bean with some dummy method, i.e. getInfo() :
@Stateless
public class MySessionBean implements MySessionLocal {
public String getInfo() {return "Hello from Session bean";}
When I lookup and use this bean in servlet in the following way, everything is OK:
public class MyServlet extends HttpServlet {
@EJB() MySessionLocal mySession;
protected void doPost(HttpServletRequest request, HttpServletResponse response) {
out.println(mySession.getInfo());
On the other side, when I create some java bean object as a facade, import and use it in servlet , it doesn't work:
public class Facade {
@EJB() MySessionLocal mySession;
public String getInfo() { return mySession.getInfo();}
public class MyServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) {
Facade myFacade = new Facade();
out.println(myFacade.getInfo());
When servlet runs and gets to the command myFacade.getInfo(), NullPointerException is thrown, because mySession object in myFacade is null (ejb lookup method probably fails to perform...)
I'm trying to use Facade to be able to use my Session Bean in JSP pages, i.e. to do something like <jsp:useBean id="myFacade" class="Facade" ...>
Could someone clarify why lookup doesn't work in javabean object, despite the fact that it works in servlets?
P.S. I'm running the latest promoted build (b31) of GlassFish (maybe this is the cause) and NetBeans IDE...

Local session bean lookup in another local session bean in EJB 3.0

Hi,
I am doing JNDI lookup of a local session bean in a session bean. ( I do not want to use EJB dependency injection).
Lookup of local interface from session bean is successful. But, when the calling session bean is a local session in another session bean, the lookup fails.
Here is an example:
@Stateless
@EJBs({@EJB(name="EJB2Local", beanInterface=EJB2Local.class),
@EJB(name="EJB3Local", beanInterface=EJB3Local.class)})
public class EJB1 implements EJB1Remote, EJB1Local{
public void findEJB3Local(){
//1. JNDI lookup for EJB3Local ----
//2. EJB3Local.someFunction()
@Stateless
@EJB(name="EJB1Local", beanInterface=EJB1Local.class)
public class EJB2 implements EJB2Remote, EJB2Local{
public void findEJB1Local(){
//1. JNDI lookup EJB1Local
// 2. Call EJB1Local.findEJB1Local method
//THIS METHOD CALL WILL FAIL.
public void findEJB1Remote(){
//1. JNDI lookup EJB1
/ 2. Call EJB1Local.findEJB1 method
@Stateless
public class EJB3 implements EJB3Remote, EJB3Local{
public void someFunction(){}
This setup was working in EJB 2.1, as we had clear ejb-local-ref definitions in our ejb-jar.xml file.
I am suspecting that EJB 3.0 has special annotation to use when lookup is made from another local session bean.
Any comments will be appreciated.
Thanks,
Mohan

From a private component environment perspective, declaring @EJB in a bean class is equivalent
to using ejb-ref or ejb-local-ref for that same bean in ejb-jar.xml. In each case, the EJB dependency
is declared for that bean. Each EJB component has its own private component environment, so
code running within invocations on different EJBs can not see the component environment of the
components that made the invocations.
What exact error are you getting? Please post the stack trace if possible.

Service Locator and session facade pattern

What are differences between Service Locator and session facade pattern?
For me it seems one and the same.
Please explain me in detail. Expecting kind help.
Thanks,

The ServiceLocator Pattern is a singleton which hold a map of used DataSources. The idea is that you perform a lookup once and use the cache afterwards. The session facade is just one DataSource lookup.huh? Those J2EE patterns are not really reduced to datasources and the SessionFacade has actually nothing to do with datasources.
Session Facade
It has Facade in it and a Facade is usually used to give a simple entrypoint by providing a standartized interface. The same is now with the Session Facade. You have a Session bean that represents a high-level business component that interacts and calls lower-level business components.
Imagine having client a accessing 5 business objects with the remote calls, which is not an efficient way (network latency) or accessing the SessionFace and the session face is doing all the work through local access.
Service Locator
As J2EE components are using JDNI to lookup for ejb interfaces,DataSources, JMS components, connections etc. isntead of writing all the lookup in many code piecess across the project, you write a service locator that gives you a centralized place to handle the lookup's. It's easier to maintain and to control such a setup.
As you can see there's quite a big difference ;-)

Diferences between Business Delegate and Session Facade

Hi, I've been programming with java for a long time now, but recently decided to formally studing the J2EE patterns. By now I have the intuition of many of them but in paper looks a little confusing. Let me ask you what is a clear diference between Business Delegate and Session Facade.
For me, exposing interfaces, hiding implementations and masking the complex interactions in the back are common factors in these patterns, could you please help me to identify diferences?

There are more subtle differences, but the basic gyst is that the Business Delegate is used on the client/presentation tier. The Session Facade is used on the server/service tier. The Business Delegate typically performs a lookup of the SessionFacade which in turn fronts a service method (EJB or otherwise). The Business Delegate pattern is typically associated with J2EE remoting and its shortcomings.

Business Delegate & Session Facade

1 What is the need of Business delegate? For controlling the interactions between the presentation tier and business tier, session facade pattern can be used.
2 Can a session facade have all the facade related methods. (i.e. entire application has only one session facade). In the pattern documentation, it is stated as this stratergy inefficient. Why is so?

1 What is the need of Business delegate? The delegate provides a client-side business abstraction and acts as a proxy for the business service. Note that it is a proxy, not a facade. In other words, it is a "stand-in" for the biz service, but it is not aggregating several method invocations into one and controlling the processing flow. So, the delegate is not providing a higher-level interface to some underlying system, as would a facade.
So what's the need, if it's just a proxy? Obviously, it adds a layer, so one must consider its benefits versus the drawback of writing, maintaining, and interacting with this extra layer. In a sophisticated system, the benefits are many and will usually outweigh the drawbacks. Following are some of the benefits of using a delegate in the web container as an access point for invocations to the business tier:
- It hides the underlying implementation details of the business service (ie: lookup, creation, access details of EJB...The delegate may use the Service Locator pattern to achieve this goal).
- The delegate translates exceptions as necessary. Service-level exceptions, such as java.rmi.Remote can be intercepted by the delegate and translated into application exceptions. This also helps shield web container clients, for example, from EJB and network-related implementation details, which they should not need to worry about.
- The delegate can attempt retries/recovery efforts transparent to its clients, such that this code can be localized and reused, instead of being duplicated in numerous clients.
- The delegate can also manage a cache of resources/results, limiting unecessary remote roundtrips
- The delegate can be used as a control point for multi-threaded access into the business tier. For example, stateful beans are not to be invoked by multiple client threads simultaneously. The delegate can serialize access, or, as mentioned above, handle exceptions/retries, as necessary.
For
controlling the interactions between the presentation
tier and business tier, session facade pattern can be
used.If you decide to use a delegate in your system, based on considering its benefits, as described above, then you'll typically create a one-to-one mapping between a delegate and a session facade. The delegate is not controlling the processing flow per se, but rather serving as a single access point and proxy as described above. The facade acts as a controller, though, aggregating the interfaces of underlying components and subsystems into a higher-level interface. If you find that your using the delegate more as a facade, we recommend pushing this control code from the web container (where the delegate lives) back to the session bean in the ejb container, so that the logic can be reused across clients.
>
2 Can a session facade have all the facade related
methods. (i.e. entire application has only one session
facade). In the pattern documentation, it is stated
as this stratergy inefficient. Why is so?Having a single facade for the entire system would prove to be quite a maintenance and manageability headache for a non-trivial application. Imagine that every time something changes in any subsystem of the service layer, developers are all making changes to the same file and the same class...Not desirable and not very elegant. At the same time, one does not want to go the other way and create too many facades by having a one-to-one mapping of session facades to use cases, for example. We recommend aggregating a group of related interactions into a session facade, so that it provides highly course-grained access and control to underlying components.
Thanks,
Dan

Flex and ColdFusion and session facade?

I want to deploy a flex application on an existing ColdFusion
server. This server is already in production and uses a root
Application.cfc to set session variables as well as authenticate
the user to AD with getAuthUser. When I deploy my flex application,
it fails because of the OnRequestStart cfcomponent within
Application.cfc. I am wondering if this would be proper use of
session facade? How do I best encapsulate session variables from
the root Application.cfc within my new flex application? Basically
I will need to follow the same authentication and cfset session
guidelines that all of my other CF applications use, and my flex
app needs to have theses session variables available to it, but I
am not sure the best approach. Any insight is welcome.

Did you enable session management in the Application.cfc or
Application.cfm?

Bussiness Delegate vs Session Facade.

Hi,
Please any one tell me what are the differences between Bussiness Delegate and Session Facade.
I read some documentation in online but not clear in above two design patterns.
Any help I will appricate.
Thanks,
CDulla.

A business delegate is generally thought of as a plug-in that is given to the client developer. This "plug-in" can do service lookups and searches on behalf of the client developer. Very smart if you have a Swing or Servlet Developer that doesn't know ejbs.
A session facade is a session bean that is much like the delegate but resides on the server and is used to encapsulate course services so that network can be held to a minimum.
A business-delegate can call a session facade which in turn can call an entity bean

Session bean lookup during MBean registration

1 Timer Session bean is created but not started.
1 static MBean is declared in orion-application.xml
In the MBean constructor, a JNDI lookup is done on the timer session bean to start the timer (method from the Timer session bean)
The JNDI lookup fails !!
Is it possible to call a session bean from an MBean constructor ??
It seems to be the same pb when i try to access a JNDI ressource (db) from any MBean constructor.
Is there a way (post construct) to access JNDI or session bean after MBean registration ?

javax.naming.Context c = new
text c = new javax.naming.InitialContext();
ejb.ejbCustomerDbLocalHome rv =
calHome rv = (ejb.ejbCustomerDbLocalHome)
c.lookup("ejb/ejbCustomerDbBean");
ejb.ejbCustomerDbLocalHome rv = (ejb.ejbCustomerDbLocalHome)c.lookup("java:/comp/env/ejb/ejbCustomerDbBean");

Confusion: Session Facade Bean

Hi all,
I have confusion regarding the Sessin Facade. I am not getting that.
I read http://java.sun.com/blueprints/corej2eepatterns/Patterns/SessionFacade.html
but still not clear...
Anybody can explain with example?
Thanks in advance.

HI..
It's very simple. For example u r writing a simple client to transfer money frm one account to another.
A typical sequence of calls involves, ( without Session Facade ).
In client code ( It could b a servelt, or jsp or anything...)
1.Get AccountHome - 1 remote call
2.lookup account1 bean - 1 remote call
3.lookup account2 bean - 1 remote call
4.withdraw money from account1 - 1 remote call
5.deposit money into account2 - 1 remote call
So you end up in making 5 remote calls and also wat if somthing goes wrong in step 5?? how will you roll back???
To avoid that we introduce a session bean called Session Fascade.. It is a simple session bean containing methods which actually performs all such operations.
U create a session bean say AccountHandlerSessionBean with a method
withdraw(String frmAccountNo, String toAccountNo){
//here u lookup and update entiry beans.
Now from the client perspective you need to do only one thing.. lookup this session bean and call withdraw() method.. simple..

In order to get a reference to you EJB Home interface from JNDI, your
application has to have an access to the stub of this interface. This stub
is generated by WL tools when you deploy your EJB. Because your servlet runs
inside the server's VM, it has an access to this stub by default. So just
include these stubs in CLASSPATH of your test program and you will see the
difference.

Session facade samples

hi,all
I am new to j2ee.any experts here could give me an sample code of session facade?in my case.I have a passwordbean (CMP entity) where stores userinfo. and a useradminbean( session bean) with remote interface.I want to write two methods createauser() and removeauser() in my SB;
the two beans are assumed to be bundled in a same jar file.so Do I have to use InitalContext.look method to call my CMP entity in SB�Hor directly call the two interfaces of my entity bean?I was lost how to write a getuserinfo() in SB which I think should call entity bean's find method.

Hi,
Your session bean is like a pojo client for lookup method.
However, it's recomended to use local interface (LocalHome, Local) between Session and Entity. (available from EJB 2.0).
I've code at home, if you need it, tell me.
Regards,
Sebastien Degardin.

Registry's EnumKey Lookup Failing When Called By MSBuild?

But that is not a portable solution. it does not apply to 32 bit platforms and will only work from a 64 bit session when calling intp a 32 bit session.
If we are in a 32 bit session running VBScript then we cannot see the 64 bit registry without the help of WMI. The correct solution is to build in the correct environment. If you want to run in both environments then you will need to test the
32 bit version on a 32 bit system assuming the applications being enumerated use the same keys on both architectures.
¯\_(ツ)_/¯
This is correct. I totally forgot there are 32 bit and 64 bit versions of MSBuild. I made no changes except to execute the main deployment script with the 64 bit version of MS Build. Thank you for all of your help.
