Why j2sdkee1.3.1 support JNDI lookup "java:comp/env" from remote client?
Hi:
I have been puzzled by this function of j2sdkee1.3.1 support JNDI lookup "java:comp/env"
from client. I always think that "java:comp/env" namespace can only be access
by the application server self for it is a private namespace. The weblogic and
websphere doest support this.
Why?
Regards!

Hi:I'm unable to get JNDI reference object from remote application client with "java:comp/env/ejb/<lookupName>".
The exception says:
Application threw an exception:javax.naming.CommunicationException: Cannot connect to ORB [Root exception is org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 201 completed: No]
The J2EE server and client are run on different machines, and needs to be like this. There isn't any problem with JSP/Servlet (cause they run/execute on the server itself). How will the client find out the JNDI refernce my mere specification of "java:comp/env/..."?
Am I making a mistake anywhere?
BEA Weblogic & IBM Websphere allows explicitly specifying the server name, while doing JNDI lookup. Is there anything similary for J2EE?
I couldn't find reference for this anywhere in the J2EE tutorial or EJB books.

Access java:comp/env from standalone client
Hi,
I am using the j2ee applicationserver from Sun.
I want to access the java:comp/env namespace from a standalone client. When I try to do this I get the following excepton:
javax.naming.NamingException: java:comp/env namespace is only available from within a J2EE component
How do I get around this?
Is it possible?
Regards
/StefanThanks a lot for giving me an answer Bart,
here is another question if you have the time.
Since it is not possible to access the the java:comp/env namesapce from a standalone client, how do I access for example a "TopicConnectionFactory" from within a J2EE application when the TopicConnectionFactory is NOT in the java:comp/env namesapce?
I have made this work but I get a warning like this:
Warning : Illegal connection factory access to TopicConnectionFactory. J2EE Components should access JMS Connection Factories through a resource-ref in java:comp/env
If this isn't possible either, then how should I use for example JMS with EJB to send messages to a standalone client?
Regards

javax.naming.NameNotFoundException. Root exception is
org.omg.CosNaming.NamingContextPackage.NotFound
=================
Below is the line of my LoginServlet class which is
referred to in the stack trace - Object object =
context.lookup
( "java:comp/env/ejb/WarehouseClerk" );The root of the naming context is 'java:comp/env' and this is where lookup automatically begins for EJBs and resources. IOW, by specifying "java:comp/env/ejb/WarehouseClerk" as the EJB lookup name the server is actually treating this as "java:comp/env/java:comp/env/ejb/WarehouseClerk". Specify only the ejb context ("ejb/WarehouseClerk") in your lookup and you should be fine.
Any help would be most appreciated.

Problems with JNDI lookup for java:comp/env/ejb
Hi all,
I'm using OC4J 9.0.3 and I have problems when looking up for the local
EJB context.
I have a SLSB which refers to another SLSB via a JNDI mapping like
shown below. Both services are deployed within one EAR file.
(snippets of ejb-jar.xml and orion-ejb-jar.xml)
<ejb-jar>
<enterprise-beans>
<session>
<ejb-name>ServiceABean</ejb-name>
<home>com.coi.ServiceAHome</home>
<remote>com.coi.ServiceA</remote>
<ejb-class>com.coi.ServiceABean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Container</transaction-type>
<ejb-ref>
<ejb-ref-name>ejb/some/sub/packages/ServiceB</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<home>com.coi.ServiceBHome</home>
<remote>com.coi.ServiceB</remote>
</ejb-ref>
</session>
</enterprise-beans>
</ejb-jar>
<orion-ejb-jar>
<enterprise-beans>
<session-deployment location="global/some/sub/packages/ServiceA" name="ServiceABean">
<ejb-ref-mapping name="ejb/some/sub/packages/ServiceB" location="global/some/sub/packages/ServiceB" />
</session-deployment>
</enterprise-beans>
</orion-ejb-jar>
The ApplicationInitialContextFactory will be used (prepared by the container),
so the lookup for ServiceB within a method of ServiceA should work as follows:
public class ServiceABean implements SessionBean
public void someMethod()
InitialContext con = new InitialContext(); // will be of class ApplicationContext
Context localEjbContext = (Context)con.lookup( "java:comp/env/ejb" );
ServiceBHome serviceBHome = (ServiceBHome) PortableRemoteObject.narrow(
localEjbContext.lookup( "some/sub/packages/ServiceB" ),
ServiceBHome.class );
The problem is now, that the lookup for "java:comp/env/ejb" doesn't work
and throws a NameNotFoundException.
To figure out what's actually happening during lookup I debugged a little bit and
tried a few things:
1. A lookup for "java:comp" works fine. It returns an instance of class FlatMapContext
which consists of a hash map which itself contains an entry for "env".
2. So a lookup for "env" on that FlatMapContext also works and returns an instance of SubContext.
3. A lookup for "ejb" using this SubContext causes a NameNotFoundException
with message "java:comp/env/ejb not found".
4. A lookup like con.lookup( "java:comp/env" ) throws also a NameNotFoundException
with message "java:comp/env not found (not inside a J2EE module, for instance a Web-App,
EJB, or Application-Client)".
Does anyone know something about this?
Regards
--thomasHi Debu,
Great! 9.0.4 will be released in june/july this year, right? Sorry for my ironical reaction, but does that mean, that I don't have any chance to get my whole stuff running in 9.0.3? I cannot believe that. Isn't there a wordaround I could apply? A setting or whatever to substitute the daft FlatCtx by something else that is implemented according to the spec?
Regards

Problem in JNDI Lookup of Deployable Proxy from the logon par file
Hi,
I have customized the Logon par file and have a functionality to call a webservice when the Password Reset happens.
<b>from the ResetPassword.jsp , SAPMLogonLogic.java is getting called ,and there is a method called performResetPassword().</b>
I am calling a Deployable Proxy in that method by using the below code,
<b>Gateway objGateway=(SMSGateway)ctx.lookup("java:comp/env/MailProxy");
MailGatewayViDocument objSMSGatewayViDocument=(MailGatewayViDocument )objGateway.getLogicalPort("wsPort_Document",MailGatewayViDocument.class);
objMailGatewayViDocument.sendMail(...);</b>
I am getting the Exception,
<b>com.sap.engine.services.jndi.persistent.exceptions.NameNotFoundException: Path to object does not exist at java:comp, the whole lookup name is java:comp/env/MailProxy.</b>
I have deployed the Deployable Proxy in the J2EE Engine and add this API Jar as the External Library (Project >Properties>Java Build Path ---> Add External jars...Added the .jar file generated in the Proxy Project).
<b>Please let me know the possible solutions where i can call a deployable proxy inside the logon par file</b>.
Thanks and Regards,
SekarHi,
I have fixed this error by changing the lookup as follows.
InitialContext ctx=new InitialContext();
Gateway objGateway=(Gateway)ctx.lookup("wsclients/proxies/sap.com/GatewayProxy/com.ms.sap..GatewayProxy");
Just open Visual Administrator and look for the path under wsclients for proper naming.
Thanks and Regards,
Sekar

Any help will be appreciated! Thanks in advance.Try removing the JNDI fully qualified name (i.e. java:comp\env\) Use the name of your bean to lookup.
It worked for me when i used to get a similar exception. -

The name "java:comp/env" is just addressesing a Context and not any object.
Suppose your bean name is "mybean". So your lookup name should be "java:comp/env/mybean".

Getting java:comp/env context in init()
Hi,
I started to write web application using servlets 2.2.
Here is the code in my init() method:
Context jndi_context = new InitialContext();
Context env_context = (Context)jndi_context.lookup("java:comp/env");

Is "java:comp/env" accessible during servlet init method? I just need to
lookup EJBHome
interface described in web.xml file. With EJBs it works. Am I missing
something with
webapp?
Thanks in advance

Java:comp/env bound and unbound at the same time
I have a ServiceLocator class which has a method that looks up and caches EJB remote home objects. I am occasionally getting a NameNotFoundException from this method telling me that env is not bound when I try doing a lookup using a JNDI name such as "java:comp/env/ejb/MyEjb". What is so odd is that this lookup is working for other JNDI names under java:comp/env, as well as in other cases when using the same JNDI name which causes the exception. It appears that env is bound in some cases but not in others.
This only occurs when I restart my JBoss server after a client has opened an HttpSession. If I also restart the client then the error doesn't occur. The client is a VB application which calls my JBoss web application's Servlets. I'm using JBoss 4.0.1.
Can anyone give me a suggestion as to where I should look for the problem? Thanks in advance.
--JamesA little more information:
The ServiceLocator is a Singleton object which runs as part of the server, and has its InitalContext bound the first time it's used (this happens in the ServiceLocator Singleton's constructor). The weirdness I'm experiencing is that it completes several lookups successfully before bombing on a lookup which uses the same JNDI name of a lookup that previously worked -- it literally works on one call and then fails on the next. The difference between the times it works and the time it doesn't is that the successful ServiceLocator method invocations originate within Servlets or EJBs and the unsuccessful invokation is made from within a JMX component. Still it's the same ServiceLocator Singleton, with the same internal InitialContext, so it would follow that the InitialContext would never lose a binding, regardless of the type of component that calls the method which does a lookup.
To further illustrate here's the scenario I'm dealing with:
1. The server is started.
2. The client is started.
3. All is well -- the client calls the servlets, which either (a) call the ServiceLocator to get EJBs or (b) invoke JMX services (MBean methods) which call the ServiceLocator to get EJBs.
4. The server is restarted.
5. The client makes a call to a servlet.
6. The servlet makes a call to the ServiceLocator method to get an EJB, and within that EJB the ServiceLocator is again called to get another EJB:
a. Lookup of java:comp/env/ejb/EJBOne is successful
b. Lookup of java:comp/env/ejb/EJBTwo is successful
7. The client calls a method on a JMX service (MBean) which internally uses the ServiceLocator to get an EJB. In this case the lookup fails:
c. Lookup of java:comp/env/ejb/EJBThree fails with the following exception stack trace:
javax.naming.NameNotFoundException: env not bound
at org.jnp.server.NamingServer.getBinding(NamingServer.java:491)
at org.jnp.server.NamingServer.getBinding(NamingServer.java:499)
at org.jnp.server.NamingServer.getObject(NamingServer.java:505)

at javax.naming.InitialContext.lookup(InitialContext.java:351)
at com.mycom.util.ServiceLocator.getRemoteHome(ServiceLocator.java:119)
etc...
7. The client receives the error and calls another servlet to refresh itself. This servlet looks up the same EJB which the JMX service was trying to lookup, and this time the ServiceLocator has no trouble finding it:
b. Lookup of java:comp/env/ejb/EJBThree is successful
In the ServiceLocator's lookup method I have added debug code to show the HashCode of the InitialContext being used, and in fact it is the same InitialContext being used each time.
What I think is happening is that normally in my application when the JMX components invoke ServiceLocator methods these methods are never doing lookups and are always getting objects previously cached by lookups made by previous ServiceLocator method calls made the Servlets or EJBs. In other words the above scenario is the only time a JMX component is invoking a ServiceLocator method in which the requested object isn't already cached and the lookup actually needs to happen. The "java:comp/env" name is somehow not available within the context of JMX, and hence the lookup fails.
So it appears that within the context of normal (non-JMX) components the JNDI name "java:comp/env" is bound to the InitialContext, but within the context of a JMX component the InitialContext temporarily loses this binding. Is this the really case? If so can someone point me to a reference in which this behavior explained?

How to bind a String object to java:comp/env name space?
Hi, does anybody know how to declare a String as a JNDI object in OC4J V904. I want to register a String named 'Foo' with the value 'val' with JNDI. Eventually I want to get the value of this by referencing this JNDI name:
java:comp/env/ejb/Foo
I don't really care how this is done either by declaring it by way of ejb-jar.xml or a global setting at the application server level.
Please assist!
Thanks
JThere are many possible ways.
- (BEST) Use the J2EE resource environment variable mechanism (ie resource-env-ref in ejb-jar.xml).
- (MEDIUM) Use OC4J startup classes.
- (IF ELSE FAILS) Use the InitialContext.rebind method. -

Neeraj HansNeeraj -
The Portal framework code (including PortalAppflowHelper) uses ejb
references to find the PortalManager (and other EJBs) from servlets and
taglibs; that is what is signified by the java:comp/env/... name.
Since you built your webapp from scratch (instead of using the portal
wizard), you will need to make sure the you have the appropriate
<ejb-ref> entries in your web.xml, and the corresponding
<ejb-reference-description> entries in your weblogic.xml. By default,
you will need at least mappings for:
- ejb/PortalManager
- ejb/UserManager
- ejb/GroupManager
- ejb/PipelineExecutor
- ejb/EventService
See either the resulting webapp from using the portal wizard or
BEA_HOME/weblogic700/samples/portal/sampleportalDomain/beaApps/sampleportal/sampleportal/WEB-INF
for example syntax.

Java:comp/env namespace is only available from within J2EE component
HI
I am writing a standalone application program to access the bean using jdk1.3.1 and it's giving me the namespace error.
I deployed the bean and included the .jar file in CLASSPATH. In the program, I specify the correct namespace to lookup since it's already registered through deployment
When I run the application, I get the exception error with namespace only available withing j2ee component.
Does anyone know what's the problem?Hi,
When you deploy your bean ( im assuming you are using deploytool ) have you added your client application as a component in deploytool ?
If you haven't done this then the client app code won't be able to lookup the java:comp/env name space. The reason is, that to access this namespace ( at least with j2sdkee1.3 ) you need a "client container". This client container is generated by the deploytool automatically if you add the client application into deploytool. Sun's sample application "Dukes Bank App" is a good place to see an example of this -
