Java:comp

(WL5.1SP6)
1) It appears that the java:comp namespace not available to a servlet. Is
that true? Is that conditional?
2) As far as I can tell, the J2EE 1.2 and Servlet 2.2 specs state that the
Servlet will have the java:comp namespace available (see Servlet 2.2 section
9.9, J2EE table 6-1, and example in 4.2.1)
For example (4.2.1):
Servlets and JavaServerT Pages (JSP)
The J2EE platform must:
-> Provide an object implementing the
javax.transaction.UserTransaction interface to servlets and JSPs.
The platform must publish the UserTransaction object in the JavaT
Naming and Directory Interface (JNDI) name space available to servlets and
JSPs under the name java:comp/UserTransaction.

OK, so no takers on this question so far. (Rob?) Let me be more explicit.
The following, according to the spec, should work in a servlet (among other
places) but does not work on WebLogic 5.1:
1) new InitialContext()
2) lookup "java:comp"
Questions:
1) Is it supposed to work in a servlet? (i.e. Did I understand the spec
correctly?)
2) Is it supposed to work in WebLogic 5.1? (i.e. Is this supported in 5.1,
or was this item not completed in 5.1, and if so, will it work in 6.0?)
3) If it is supposed to work in WebLogic 5.1, then under what conditions
would the java namespace NOT be available? (i.e. What the *@^# is wrong
with the code/configuration?)
Here's some test code (with the exception line (118) clearly marked) so you
can see how I tested it in a servlet:
public void service(ServletRequest req, ServletResponse res)
throws ServletException, IOException
try
Context ctx = new InitialContext();
PrintWriter writer = res.getWriter();
writer.println("<html><block><pre>");
writer.println("** listing java:comp");
list((Context) ctx.lookup("java:comp"), " . ", writer); // <--
line 118
writer.println("</pre></block></html>");
writer.close();
catch (Throwable e)
e.printStackTrace();
private void list(Context ctx, String s, PrintWriter writer) throws
Exception
for (Enumeration enum = ctx.listBindings(""); enum.hasMoreElements(); )
Binding binding = (Binding) enum.nextElement();
String sName = binding.getName();
String sClass = binding.getClassName();
Object o = binding.getObject();
if (o instanceof Context)
writer.println(s + sName);
list((Context) o, s + " . ", writer);
else
writer.println(s + sName + " [" + sClass + "]" + (o == null ? "
***NULL***" : ""));
Here's the exception from the InitialContext.lookup:
java.lang.NullPointerException

Could not lookup PortalManagerHome in the JNDI tree using EJB reference java:comp/env/ejb/PortalManager

Hi
I am just a starter on WLPortal.
I have created a barebone Application from scratch. I have synchronized it properly
from EBCC to WLP. But When I am trying to access the home page of my application,
I am getting from stack trace -

catch(Exception e)

I have checked the PortalManager's JNDI name on WLConsole. Its ${APPNAME}.BEA_portal.PortalManager.
Should I change it?
When I tried to change it, I started getting other weird errors.
Thanks

Neeraj -
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.

Greetings,
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.
SeanRegards,
Tony "Vee Schade" Cook

I have developed a search servlet and deployed it in tomcat 4.0.3 and connected to mysql database through jdbc by specifying jndi.
I have coded JNDI lokkup name as "java:comp/env/jdbc/KgoogleDB"
I have added a context in server.xml file of tomcat for DBCP connection pooling .I have tested this in windows and it is running well in it.
But when i hosted this in linux i got error like this
INIT OF SEARCH SERVLET
Error in file reading Connection refused

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
--thomas

Hi 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

Lookups with java:comp/... not working

Hi,
when I bind an object to the jndi tree, e.g. "/mysubcontext/myobject", I
can't perform a lookup on "java:comp/mysubcontext/myobject". If I try to
lookup "/mysubcontext/myobject" it works fine. Isn't the lookup with the
java:comp prefix supposed to do the same?
Thanks,
Daniel

thanx this is the solution. With this construct
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:java="http://xml.apache.org/xalan/java" exclude-result-prefixes="java">
     <xsl:output method="html" indent="yes" encoding="iso-8859-1"/>
     <xsl:template match="/">
     <xsl:variable name="counter" select="java:java.util.Vector.new()"/>
     <xsl:variable name="temp1" select="java:add($counter,'1')"/>
     <xsl:variable name="temp2" select="java:add($counter,'2')"/>
     <xsl:variable name="temp3" select="java:add($counter,'3')"/>
     <xsl:variable name="temp4" select="$temp3"/>
     <xsl:value-of select="java:size($counter)"/>
     <xsl:value-of select="java:toString($counter)"/>
     </xsl:template>
</xsl:stylesheet>
at least the '3' is added to the vector.

What is the meaning of java:comp/env in (?java:comp/env/jdbc/mssql?) ?

I know that we are suppose to give jndi names starting with jdbc/
But i have a sun book in which they created a jndi with jdbc/ejbUserAccount and later referred it with "java:comp/env/jdbc/UserAccountDB"
also in this blog this guy has done the same ..
http://vchaithanya.wordpress.com/category/java/
please help !!

no we're not!

That's how he defined it, apparently. Or rather the application(server) that provides the resource through JNDI.
please help !!It's just a name. It could be anything, but usually they are descriptive.

NameNotFound exception for java:comp/WorkContextMap

Hi,
we need to write a context propagation code. I tried the same using the example from - http://e-docs.bea.com/wls/docs90/programming/context.html#1058673. I have written the web service and it is getting the jndi for java:comp/WorkContextMap OK from it's own initial context. However, when I am writing a standalone java client to use WorkContextMap from the client side by getting a initial context to the weblogic 9.2 server by setting the initial context factory and the provider url, it does not work. I also tried by using only "WorkContextMap" in place of "java:comp/WorkContextMap". but that does not work either. How can this be fixed?
Just to test, I also tried to doa look up of "java:comp/UserTransaction" from the standalone client and it did not work either. I tried with different types of the jndi string - like with and without java:comp.
Here is the client code snippet -
               Hashtable env = new Hashtable() ;
               env.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
               env.put(Context.PROVIDER_URL, "t3://172.20.8.211:7001");
               InitialContext ctx = new InitialContext(env) ;
               logger.info("in testEchoService...InitialContext=" + ctx) ;
               WorkContextMap map = (WorkContextMap) ctx.lookup("java:comp/WorkContextMap") ;
               logger.info("in testEchoService...map=" + map) ;
Appreciate your help,
Thanks.

The issue you are seeing has to do with client initialization - which is a big and hairy topic I won't bore you with. The simplest way to get this working is to use the J2EE appliction client which will ensure proper initialization - including the comp entries.
weblogic.j2eeclient.Main
You will need a generated client jar as well I believe.

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.

I'm using JBoss Seam as my web framework, and the Seam container is starting up successfully after deploying my WAR file. I get this stacktrace when I hit my first page.
I googled "java:comp/EJBContext" and it looks like it's a standard EJB3 resource which should be available. Any ideas?

I figured out how to get JBoss Seam working with OC4J 11 and wrote it up here:
http://wiki.jboss.org/wiki/Wiki.jsp?page=SeamOC4J11g
By the way, the solution to this particular problem was I didn't need to have any content in my jndi.properties at all, and I was trying to use java.naming.factory.initial=com.evermind.server.ApplicationClientInitialContextFactory (or com.evermind.server.rmi.RMIInitialContextFactory).

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

Java:comp/env namespace is only available from within a J2EE component

Can someone help me to explain and resolve the Exception?
The Exception is like below:
javax.naming.NamingException: java:comp/env namespace is only available from within a J2EE component

Hi temp,
I can only guess here -- since you haven't provided much information,
but if you are trying to lookup an EJB from some client class, then
the client class must also be deployed to OC4J in order to use the
"java:comp/env" namespace.
I think if you did a search of this forum's archives for the text
"java:comp/env", it would probably explain lots of things to you.
Good Luck,
Avi.

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
J

There 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.

Why only j2sdkee1.3 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?

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.
