Getting Tomcat 4.1 to call EJBs in WLS 8.1

I know this is not necessarily a new topic, but we're upgrading our Tomcat
4.1 -> WLS 5.1 to a Tomcat 4.1 -> WLS 8.1 configuration.
Firstly, has ANYONE got Tomcat 4.1.x to work with a post 5.1 container at
all? Ever?
We are using the T3 protocol to talk to our beans, and the goal, of course,
is that our Tomcat based client code will ideally not have to change.
Our beans are all EJB 1.1, and I have them loaded into a running WLS 8.1
container. They appear to work.
The way I tested to see if I could talk to WLS was by using a simple client
that I had that gets an InitialContext, and then grabs a bean.
I now have a simple JSP that essentially does the same thing. I've bundled
this jsp into a properly formatted WAR file.
Within this WAR file in the WEB-INF/classes directory are the Session bean
Home and the Session Bean Remote interface classes.
Within the WEB-INF/lib directory is the
c:\bea\weblogic81\server\lib\weblogic.jar, slightly modified.
After the first attempt to load this, Tomcat would complain because the
weblogic.jar contains the javax.servlet package, so I exploded the
weblogic.jar file, renamed javax/servlet to javax/servlet.x, and then
rejarred the file. This file was placed into the WEB-INF/lib directory.
This is otherwise a default Tomcat 4.1.18 binary package.
Here's the WAR file contents:
./META-INF/MANIFEST.MF
./WEB-INF/classes/com/pfizer/ecms/as/CustomizationSession.class
./WEB-INF/classes/com/pfizer/ecms/as/CustomizationSessionHome.class
./WEB-INF/lib/wlsx.jar <-- Edited weblogic.jar
./WEB-INF/web.xml
./test.jsp
This is the contents of the test.jsp:
<%@ page language="java" %>
<%@ page import="javax.naming.*" %>
<%@ page import="com.pfizer.ecms.as.*" %>
<%
try{
System.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
System.setProperty(Context.PROVIDER_URL, "t3://localhost:7001");
InitialContext ctx = new InitialContext();
CustomizationSessionHome csth = (CustomizationSessionHome)
ctx.lookup("CustomizationSession");
CustomizationSession cst = csth.create();
catch (Throwable t) {
System.out.println(">>>t = " + t);
t.printStackTrace(System.out);
%>
<HTML>
<BODY>
This is the jsp.
</BODY>
</HTML>
Similar code to this has been working for us for 3 years so far.
When I try and load the JSP, it dumps a stack trace. Here's the relevant
bits up to the Tomcat container:

What is interesting about this is that the system could "see"
weblogic.utils.classloaders.GenericClassLoader, but THAT class could not
find weblogic.rmi.extension.server.Stub, even though they are, ideally, at
the same level within the Tomcat imposed hierarchy of classloaders.
Unfortunately, we don't quite know where in that hierarchy each class is
placed.
Now, the culprit may well be java.security.SecureClassLoader (or, actually,
the java.lang.ClassLoader.defineClass0), which is very high up in the
hierarchy trying to load a the result of the StubGenerator, only to find
that an associated class, weblogic.rmi.extensions.server.Stub, was "not
found" because it only existed deep in the Tomcat hierarchy.
One way that I tried to get around this was to start taking selective bits
of of weblogic.jar and put them on the system CLASSPATH used by Tomcat when
it starts up.
This gets us farther along, in that more classes seem to load without
getting the ClassDefNotFound error, but it finally leads us into this
exception:
The error is, with a small bit of stack dump:
weblogic.utils.AssertionError: ***** ASSERTION FAILED *****[ Environment not
found on thread ]

Now, according to the Weblogic documentation, the AssertionError exception
"is impossible". Well, that's my job they say, doing the impossible.
Minimally, it's a meaningless message to me and pretty much stops me cold.
I have seen other discussions about Tomcat and how it's not J2EE, etc, and
perhaps my expectations that this will work are too high. My concern with
that is simply that in our case, Tomcat is a Fat Client no different from
"any other Java application". We just use Tomcat to talk to beans rather
than a custom client. The difficulty, it seems, is in the complexities of
the Tomcat class loaders interoperating with the expectations of Weblogics
classes et al.
I've got a small application that does exactly what Tomcat wants to do, so
"weblogic works", except of course, in Tomcat.
So, in the end, I'm curious if others have some data on getting these two
system cooperating. If anyone has any other ideas on how to use Tomcat as a
client of Weblogic 8 that utilizes techniques besides replacing Tomcat
(which is not an option at the moment) I'd like to hear those as well. I
have been fighting this for days, and tried several things, but nothing
"obvious" seems to help.
Weblogic 8 has a "thin client" jar, but it's only useful for RMI rather than
T3, plus it's still not clear how we'd go about rewriting the interfaces to
support that versus the standard EJB interfaces already created for the
beans.
Any assistance greatly appreciated.

Of course I feel obliged to first recommend that you run your webapps
and EJBs in WLS. There's significant performance advantages and it
greatly simpifies your life since you don't have to deal with another
remote failure case.
That being said, I believe it should be possible especially with 8.1 to
make Tomcat a WLS client.
Answers inline.

The question is what protocol (eg T3, JRMP, IIOP) will actually run RMI.
By default WLS uses its own protocol (t3), but most customer apps
should run without change over IIOP.
I'd really recommend going the thin client route. Otherwise I fear
you'll end up with a heavily modified weblogic.jar and headaches when
you try to install a service pack etc.

Call EJB in WLS 7.0SP2 from WLS 5.1 SP13

Hello,
I am trying to call an EJB deployed on WLS 7.0SP2 from a WLS 5.1 SP13.
There are issues from 19 Dec 2002 in "weblogic.developer.interest.rmi-iiop" newsgroup

seems to be the same as the interoperability between WLS 6.1SP2 and WLS5.1SP12

with "weblogic.ejbc -iiop" in WLS 7.0 and client classes generated with "weblogic.ejbc

New To Iplanet app server.Can some one help me getting started by delpoying and calling one of each of these:JSP,Servlet,EJB.Tried with iplanet docs..didnt quite get it. thanx

Hi,
What is that you are trying to accomplish ? Is it deployment or
trying to develop applications ? Are you getting any errors ? If so,
please post them to help you. I think the documentation is the best place
for you to begin with.
Regards & Happy New Year

Thread hang during call EJB 3.0 with Weblogic 10.3 (Urgent)

Hello,
We have a java client application call Weblogic Appserver 10.3, EJB 3.0 Service. Occasionally, client application, some step will get hang when try to invoking EJB. When we restart the application server and re-run the client application, it may work or hang on any other step. (Totally, we have around 40 steps to invoking EJB service)
We did check Google and find similar issue happen on the IBM Websphere appserver. They post a patch to fix this issue (http://www-01.ibm.com/support/docview.wss?rs=180&uid=swg1PK74719), but not Weblogic.
Is there any Weblogic expert who can help me to solve this issue?
I have attached two thread dumps (different steps) when they got hang.
Appreciate your quick help.
Best wishes,
Feelyn

I used a writen example that calls EJB from HTML via SERVLET. Example name is Bonus. The problem I have is that the HTML throw error while calling SERVLET. I dont figure out what seams to be a problem. Someone know?

WDP calling EJB and passing objects of classes from Java project

Hi.
We have <b>Java</b> project which contains some classes common for all projects (like xxx.Version).
We have <b>EJB</b> project which defines EJB interface using these common classes (like getVersion(String,int): xxx.Version and getCurrency(String,xxx.Version,int):xxx.Currency ).
We have <b>Web Dynpro</b> project which calls EJB:
1. Lookup is successful
2. call to getVersion is successful
3. call to getCurrency fails with <b>NoSuchMethodException</b>:

How can I set dependencies to get this running?
Thanks to all
       Volker

Hi,
Is it available in the interface you are using..
If the answer is yes.. you might have probably forgotten to deploy the EJBs ear file after making the changes..
Rebuild it.. and deploy the EJB s ear file again..
It will solve the problem.. If that also does not work,it might be a problem with the cache.. restart the server..
It should work now !

How to Call EJB from coldfusion

I need to call EJB that's created in JBoss from coldfusion.
I'm getting different errors depending on how I set the home object
and provider url.
If I prefix provider url with jnp://, then I get the
following error
The connection to the remote JNDI server on host jnp at port
1099 has failed (as have all backup hosts listed, if any) - please
verify that the server is running and the NamingService is
available
If I take the jnp out and keep just the ip address and port,
then i get the following error
null (no security manager: RMI class loader disabled).
So I'm not sure what the issue is and I haven't used this
feature before.
Here's my code

I tries to call custom EJBfrom custom component received
follwong error
ERROR [STDERR] javax.naming.CommunicationException [Root exception is java.lang.ClassNotFoundException:
No ClassLoaders found for: com.mycom.myapp.action.interfaces.pm.ejb.PmFacadeRemote
(no security manager: RMI class loader disabled)]
any idea?
Thanks

Calling EJB from an applet in 9iAS Release 2?

Hello!
In 9iAS Release 1 it is not so easy to call an EJB from an applet. First the applet needs special privileges and then the applet starts only once. The cause of problem is the implementation of ormi.
Will 9iAS Rel. 2 support Applets calling EJBs?

Jeff,
I am also trying to make an applet client for an EJB deployed to OC4J.
I modified the java2.policy file as you suggested, but when I tried to run my applet, I
got the following error:
java.lang.ExceptionInInitializerError: java.security.AccessControlException: access denied (java.util.PropertyPermission tunneling.shortcut read)

I am using OC4J (stand-alone) version 9.0.2.0.0 on Solaris 7 and Microsoft Internet Explorer
5.0 with the java 1.3.1 plug-in.
Here is the applet code that I use to lookup the EJB home interface:
Properties props = new Properties();

Object homeObj = ctxt.lookup("my_bean");
MyBeanHome home = PortableRemoteObject.narrow(homeObj, MyBeanHome.class);

Calling EJB from Oracle via IIOP

I've spent the last two days trying to figure out how I can call an
EJB from an Oracle Stored Procedure. I first looked into WLS JNDI
(Using WLInitialContextFactory ), but my collegue recommended I look
into IIOP because it is "less proprietary". I was able to get a WL
example working that does a lookup on an EJB and "narrows" the IIOP
object...so it looked promissing, but then I tried to load the JAR
into Oracle and it said:
"referenced name javax/rmi/PortableRemoteObject could not be found"
So I did a quick check and it looks like this didn't come into
existance until JDK 1.3. By all accounts, Oracle 8.1.6 supports JDK 2
(1.2). So now I'm stuck. I've got a few examples about connecting to
the Oracle ORB using session-iiop, but I don't know if Weblogic will
be able to work with this. I don't know how I'd even call it because
the URL requires an Oracle SID...so now what? I see three options.
Please let me know which would be best (or another option that I'm
missing)
1. Try connecting with Weblogic "T3"
2. Try to get the right combination of classes loaded so 1.2 can work
like 1.3
3. Use the Oracle IIOP (I have no examples for connecting to other
ORBs so I have no idea how to lookup objects).

1. Try connecting with Weblogic "T3"It depends on what version of WLS you are using. If you are using 6.1
then you are out-of-luck because this only support JDK 1.3.1.We are using WLS 6.1 and Oracle 8.1.6. There's got to be a way to
connect what is essentially a 1.2 JVM to a 1.3.1 JVM. On my way home
yesterday I was wondering if just straight RMI would work...although
we need to encrypt the connection. I've seen several people talk
about calling EJB's from stored procedures so it seems like there is a
way. Any other ideas?The really gross way is HTTP. In a previous life I had a customer use
oracle's HTTP plug-in to do this. You could probably invert the
problem also. I.e. write CORBA objects that sit inside an Orb hosted
in WLS and invoke on those using oracle's CORBA support. But HTTP is
probably the way most likely to work. You probably couldn't use RMI
over HTTP either - you would have to write a servlet that delegated to
your beans.

Calling EJB from JSP

Hi - I'm running OC4J 9.0.2 on windows 2000
I have a JSP that accepts user inputs and the call respective Servlets. Before the servlet gets called, I want to log a tracing event with an EJB(Stateless Session Bean).
I have manipulated the "form" values with JavaScript but cannot find any docs on how to call an EJB from JavaScript in a JSP.
The JSP and EJB works fine on there own. How do I get the "form" values into the EJB variables without JavaScript?
The EJB logs fine while still in the "JAVA" part of the JSP but I don't know how to extract these 2 index values.
Tks

Hi Christian,
A few questions to clarify where the cause of the problem might be:
1. When you run the JSP app in JDeveloper, are you connecting to the remotely deployed app module, or the local one in your workspace?
2. In your JSP project, there is an appmodule.properties file. This file should specify the connection mode to use to connect to your EJB (ConnectMode=EJB), and should be deployed to a directory on your webserver's classpath, along with the connections.properties file. If the appmodule.properties file contains the wrong connectmode setting, or is not on the classpath for the webserver, this might be the cause.
Let us know.

Calling EJB from XI Mapping

Hello,
i try to call a ejb (deployed on the same machine) within a message mapping (userdefined function).
Is there any documentation how to do the jndi lookup?
Do i have to pass user credentials in order get working jndi-lookups. Currently i get only sap....UnsatisfiedReferenceImpl Objects from the context.lookup(...).
As far as i can see there is no binding of my ejb visible for lookups (tracing the content of context.list("")).
Do i have to load a foo_client.jar into xi or not. Are there other jars to load into xi to get it work .....?
Thanks
Peter

Calling EJB method

Hi All,
I have never worked with EJBs so I am kind of stuck with one problem.
I have to make use of one existing EJB project through my external standard java class. The existing EJB project makes use of some other packages which are also EJB projects and I am not allowed to change any functionality of the EJB project but to use them as it is.
I am just initilizing the class object of the EJB project and calling its method. Within the EJB project there is a method which is calling another method of another EJB class.
The problem is that I dont see this other EJB class object getting initilized first and then calling its method as it happens in a normal scenario, hence when that method gets called i get a null pointer execption.
Let me give you some idea by posting some code snippet.
@WebService(targetNamespace = "http://www.ttt.de/ota")
@SOAPBinding(style = SOAPBinding.Style.DOCUMENT, use = SOAPBinding.Use.LITERAL, parameterStyle = SOAPBinding.ParameterStyle.BARE)
// standard EJB3 annotations
@Local(AMSAgencyWSPortType.class)
@Stateless
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW)
// jboss propriatary annotations
@WebContext(transportGuarantee = "NONE", secureWSDLAccess = false)
public class AMSProfileServiceBean extends AbstractProfileBuilder implements AMSAgencyWSPortType
private static Log log = LogFactory.getLog(AMSMappingServiceBean.class);
@EJB(mappedName = "PotsdamProfileService/local")
private PotsdamProfileService profileService;
private Security              security;
@EJB
private OTAProfileBuilder     otaProfileBuilder;
@Override
public OTATTProfileReadRS otaTTReadRQ(Holder<Security> wsseHeader, OTATTReadRQ request)
     security = wsseHeader.value;
     BigDecimal requestVersion = request.getVersion();
     OTATTProfileReadRS otaProfileReadRS = new OTATTProfileReadRS();
     otaProfileReadRS.setVersion(requestVersion);
     PotsdamInstanceKey profileIntanceKey;
    try
      profileIntanceKey = getKeyHandler(requestVersion).buildUserKey(wsseHeader);
      PotsdamInstance userInstance = loadProfileFromPotsdam(profileIntanceKey);
private PotsdamInstance loadProfileFromPotsdam(PotsdamInstanceKey userCredentials) throws PotsdamException
       PotsdamInstance potsdamInstance = null;
       try{
    Holder<com.ttt.potsdam.common.messages.Security> wsseHeader = buildWsseHeader(security);
    ProfileResponse potsdamInstanceRS = profileService.loadProfile(wsseHeader, userCredentials);
...I get an error message before the sequence reaches loadProfile(..), which in my sense is due to the fact that 'profileService' never was initilized in the EJB project.
profileService is object of another EJB project, which looks somethign like this:
@Stateless
@LocalBinding(jndiBinding = "PotsdamProfileService/local")
// jboss 4.2
@org.jboss.annotation.ejb.LocalBinding(jndiBinding = "PotsdamProfileService/local")
public class PotsdamProfileServiceBean implements PotsdamProfileService {
     private static Log log = LogFactory.getLog(PotsdamProfileServiceBean.class);
     @EJB
     private CacheProfileService cacheProfileService;
     @EJB(mappedName = "/PersistenceUnitsManagerBean/local")
     private PersistenceUnitsManager persistenceUnitsManager;
     @EJB
     private PotsdamService potsdamService;
     public ProfileResponse loadProfile(Holder<Security> wsseHeader,
               PotsdamInstanceKey cacheInstanceKey) {
           log.debug("inside loadProfile");
...Now I am calling the main EJB like this:
PotsdamotaTTReadRQ();
public OTATTProfileReadRS PotsdamotaTTReadRQ()
       AMSProfileServiceBean a = new AMSProfileServiceBean();
       Holder<Security> wsseHeader = new Holder<Security>();
       OTATTProfileReadRS response = a.otaTTReadRQ(wsseHeader, request);
       return response;
}So my confusion is how can I make use of profileService.loadProfile(wsseHeader, userCredentials); ??
I tried to initilize: PotsdamProfileServiceBean profileService = new PotsdamProfileServiceBean();but I get jndi binding and lots of other exception.
Please help.

Thanks for your pointer. Could you please help me out with a small code snippet example?
I want to make use of this existing bean (AMSProfileServiceBean ):

@EJB
private OTAProfileBuilder     otaProfileBuilder;
@EJB
private OTAProfileUpdater     otaProfileUpdater;
@Override

...in my soap-connector :
@WebServiceProvider(wsdlLocation = "WEB-INF/wsdl/PotsdamAMSAgencyWS.wsdl", targetNamespace = "http://www.ttt.de/ota", serviceName = "PotsdamAMSAgencyWS", portName = "PotsdamAMSAgencyWSPortType")

Calling EJB in WebDynpro JavaBean model

Hi,
we have our business logic encapsulated in EJB's. Due to performance issues we don't want to call the EJB's via the webservice model in Web Dynpro. Thus we decided to use the Java Bean model in Web Dynpro and call the EJB's we need in the execute method of the Java Bean.
This worked fine before we migrated from FP12 to FP14. Now we get a
java.lang.NoClassDefFoundError: javax/ejb/EJBHome
exception when we try to access the EJB in the execute method of the Java Bean.
This happens although we have defined a library reference to
sap.com/ejb20
in project properties -> Web Dynpro References.
Did we miss something in order to use the ejb20.jar?
Any help to this topic is appreciated.
Greetings.
Achim

Hi,
we have exactly the same problem!! We also use FP14
Please help!
Greetings
