Problems Accessing EJB from Client
Hello All,
I have deployed my first EJB in my JBoss App server and thats fine. However when I try and run the simple client that I have written to access this I get the following error:
javax.naming.NoInitialContextException: Need to specify class name in environment or system property, or as an applet parameter, or in an application resource file: java.naming.factory.initial
I have tried Debugging the app and cant understand where/why this error is occurring? Any ideas and suggestions would be appreciated...The code I am using in the client is below:
Context c = new InitialContext();
Object o = c.lookup("HelloWorldEJB");
HelloWorldHome hw = (HelloWorldHome)PortableRemoteObject.narrow (o, HelloWorldHome.class);
HelloWorld hello = hw.create();
System.out.println ("Result is: " + hello.hello());
hello.remove();
Hi!
I do not know if you have got the solution for your problem....
I am also struggling around with similar issue
Here is how i tried
Properties prop = System.getProperties();
prop.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
prop.put(Context.PROVIDER_URL, "localhost");
prop.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces" );
Context ctx = new InitialContext(prop);
System.out.println("looking up ejb");
Object obj = ctx.lookup("ejb/test");
DO NOT forget to put jbossall-client.jar and jnpserver.jar in your classpath .
This way at least you get the solution of the problem you are facing now.....
Good Luck

Problem accessing ejb from servlet
Hi,
I'm aving a problem accessing a stateful session bean from a servlet. I'm using a jndi lookup to do it because I need that a client has its own bean reference...
My code into the service method is:
InitialContext ctx;
try {
ctx = new InitialContext();
carrelloService = (CarrelloLocal)ctx.lookup("java:comp/env/ejb/Carrello");
and I have a reference to EJB into web.xml:
<ejb-local-ref>
<ejb-ref-name>ejb/Carrello</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<local-home></local-home>
<local>carrello.model.CarrelloLocal</local>
</ejb-local-ref>
If I use @EJB annotation to inject the servlet, it works fine.
Instead using jndi lookup throws a NamingException because it doesn't find java:comp/env/ejb/Carrello entry.
Any idea about the problem?Here's something simple that I have that works:
<p> </p>
SimpleBean
<p> </p>
@Stateless(name="SimpleBean")
public class SimpleBeanBean implements SimpleBeanLocal {
<p> </p>
web.xml; -- note I use a whacko ejb-ref-name just to make it obvious where I'm using it.
<p> </p>
<ejb-local-ref>
<ejb-ref-name>ejb_mapping_doodad/SimpleBean</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<local>sab.otn681398.ejb.SimpleBeanLocal</local>
</ejb-local-ref><p> </p>

out.println("<html>");
out.println("<head><title>TestServlet</title></head>");
out.println("<body>");
out.printf("<p>The %s bean has been hit: %s times</p>", simple, simple.getHitCount());
out.println("</body></html>");
out.close();
private SimpleBeanLocal createSimple() throws NamingException {
return (USEENC==true? createSimpleViaENC(): createSimpleViaName());
private SimpleBeanLocal createSimpleViaENC() throws NamingException {
InitialContext ic = new InitialContext();

Com.adobe.processingException : Problem accessing data from destination
hi guys,
i have an ECC 6.0 server(db : sql) and i am getting the below error while testing the destination service
(((com.adobe.processingException:Problem accessing data from destination
dest: fp_icf_data_isp)))
i checked rfc connection and it is working fine .
i dont remember the ADS_AGENT password for checking the user.but i have provided all the required roles for that.
please guide me to resolve this issueHi
When you say you checked the rfc are you refering to the one in SM59? The fp_icf_data_isp should be an entry in the visual admin of the server that runs the ADS. In the visual admin under server->services->destinations goto to the http folder and check that there is an entry with that name there. Also the address should be http://<host of abap system>:<abap http port> and the client field and username field should be filled in.

Hi,
I am trying to understand how WLS 7.0 secures a call to an MBean. Got
the following
scenario:
- I am in a servlet context
- I have created and registered an MBean with the WLS MBeanServer. Fine
so far
- Within the same call I can retrieve the MBean attributes. Fine so far
- I keep the MBeanServer reference in an object global to the servlet
context
The problem:
- When I do another request and try to use the cached MBeanServer
instance to
access the MBean, I get the following error:
weblogic.management.NoAccessRuntimeException: Access not allowed for
subject:
principals=[], on ResourceType ...
Any idea?

AlainWhat ResourceType are you trying to access. From the Exception you're
trying to access it as an Anonymous user (principals=[]) and evidently
you're attempting to access something that is protected. I can't tell
what
from the snippet you've included.
Using M2, Opera's revolutionary e-mail client: http://www.opera.com/m2/
Thanks Paul for your reply.
You are right. I can access my custom MBeans if I am authenticated for example
as an Administrator. My problem is that I want any application to access this
MBean authenticated or not. I am trying to find how I could grant permission to
this MBean to everyone. Still searching.
Thanks. -

What is the easiest way to access the router from an iPad? I have no problems accessing it from my laptop. Even though I am entering the address in the left address box, not the Google search box, it wants to do either a search, or add www to the beginning of the IP address.
I usually can eventually access the router, but it is way to much trouble. However, I use my iPad hundreds of times more often than my laptop.Are you typing http:// in front of the IP address of the router? e.g. http://192.168.0.1
Sometimes, and with some routers it doesn't seem to like it if you miss off the http:// -
ADS, Problem accessing data from Destination
Hello All,
I'm facing an error when executing transaction TRIP.
If I use the standard Adobe form it's OK no error.
If I use a Z-form copy of this standard form (after doing customizing in PE03) I have an error message: Error while initiating travel form
When I was deeper in the debugging I found that there was an exception rose which is:
ADS: com.adobe.ProcessingException: com.adobe.ProcessingException: Problem accessing data from Destination: ...
I found some threads talking about ADS and transaction SM59u2026
When testing the connection in tx SM59 I have an error message 403: forbidden access
Is it the cause of the error generated in TRIP tx?
If yes why using the standard form works fine??
Thank you in advance for your help.
Regards,
Moez.Hello Otto,
Yes I'm using the same user for the two forms.
It works for the standard form and not for the Z-form.
That's why I'm expecting a customizing issue to resolve this problem.
All solution that I found are talking about administration and Visual Admin tool.
Regards,
Moez. -
SYSTEM ERROR : com/adobe.processingexception:Problem accessing data from De
Hi SAP Guru,
We have configured ADOBE for separate ABAP server and Java Server.
But when I am execution report FP_TEST_00 getting below error
ADS: com.adobe.ProcessingException: Problem accessing d(200101) Message no. FPRUNX001
FP_CHECK_DESTINATION_SERVICE
FP_CHECK_HTTP_DATA_TRANSFER giving error

But report fp_pdf_test_00 is giving postive response.
I have troubles hooted according to note 944221 , my configuration is ok but no success.
Please help to resolve this issue.Hi,
Check your ADS Connection .
Do one thing
Go to T-code "SM59" - "RFC Destinations (Display/Maintain)"
select "HTTP Connections to External Server" - > ADS
Double click there and check the all the settings " Administrations " , Technical setting , Logon and security , Special option .
Please check the log on and pass word with the help of your SAP BASIS consultant it will work fine . -
This error message has many threads. However, I have not seen any postings for NW CE 7.1. The configuration for this version of JAVA and ADS is very different from any of the documentation that we have found. We suspect a config issue but cannot find any pertinent documentation for ADS configuration and NW CE 7.1 (we are SP11).
Where can we find ADS configuration documentation for NW CE 7.1?
Please help.
So far, we are mainly using test FP_CHECK_DESTINATION_SERVICE which seems to prove that the destination configuration is the problem. Fortunately, some of the configuration was automated. But not all.Thanks for the help, so far. I have gotten one step closer by manually starting all processes and services related to Adobe Document Services. CE 7.1 is quite a bit different.
I can now get a byte count returned with the test FP_CHECK_DESTINATION_SERVICE in SE38 without checking the "with destination service" box. When I check the box, I still get the "Problem accessing data from Destination: dest:FP_ICF_DATA_<SID>//sap/bc/fp/ message".
The problem is related to the return of the rendering service from the Java side via the Java destination service.
Note that the ABAP side with the problem is ECC 6.0 EHP3 SP1. -

Security exception while trying to access EJB from stand alone client
Hi!, I am trying a sample EJB application to R&D some security related issues. I want to access EJB through a web application as well as a stand-alone client. I have set approriate <method-permission> in EJB deployment descriptor. I am using users.properties/roles.properties file for authentication mechanism. I am using JBoss 3.2.
- On the web application side I am using BASIC authentication and the servlet is able to access the EJB OK, as long as I am using a login/password that has access to the EJB.
- Now I am trying to access the EJB using a stand alone Java class. These are the things I have tried till now:
=>Created a InitialContext with appropriate principal, credentials and tried getting a reference to EJB home interface. That resulted in security exception.
=>Logged into a LoginContext by using appropriate JBossSX classes and then tried getting a EJB home interface. Again security exception.
Now I am not sure what to do. I read at some places about client side container but not sure what that is. Does anyone has any ideas to try? Is there any other way I can make a swing application and a web application authenticate to EJB container?
Also can anyone point me to any documentation that gives some idea about how the security credentials gets propagated from web application/standalone client to EJB container?It would be better if you can post your code...and DD that way we can help you better

Issue in accessing EJB from plain java
Hi,
I am new to OAS. I am using OAS 10.1.2.
I want to access EJB which runs inside OAS, through a plain java program which runs from outside the OAS environment (standalone java program).
I am confused on what to use. RMIInitialContextFactory or ApplicationClientInitialContextFactory for the context in the java program.
what should be the provide URL ?
java.naming.provider.url","ormi://hostname:18140/
is it "ormi" or something else? what is the port number should i use. there are many ports in this OAS. i see that in the console("Ports") link.
also let me know what should i mention in the EJB xml descriptor.
Is this lookup to be done by retrieving from jndi?
pls help.
Thanks,
Sukumar
with this confusion i developed an EJB with the following details
ejb-jar.xml
<ejb-ref>
<ejb-ref-name>ejb/testDetails</ejb-ref-name>

pls helpHi,
you do not have to package your EJB and PAR together! You can deploy them separately and then reference the J2EE Application from your PAR or vice versa to access it.
For instance you can access the EJB from your PAR as described here:
http://help.sap.com/saphelp_nw2004s/helpdata/en/42/9ddf20bb211d72e10000000a1553f6/frameset.htm
Or you can access a Portal application from J2EE like described here:
http://help.sap.com/saphelp_nw2004s/helpdata/en/42/9ddd0cbb211d72e10000000a1553f6/frameset.htm
Even if you package your PAR in to the same EAR with your EJB they will result in two different containers on the J2EE Engine and you will have to reference them as described in the link above to access the functionality of one component from the other.

Stefan Brauneis -

If I add my servlet classes, aurora_client.jar, mts.jar, vbjapp.jar and vbjorb.jar files to the CLASSPATH, it works fine.
The behavior is the same in JRun and Tomcat.
I don't like this solution since I have to make the CLASSPATH point to my application classes at the web server level instead of at the application context level.
Has anyone been able to solve this problem?
Thanks for your help.
nullYes, I did. Actually, if I run my servlet in JDeveloper (Web-to-Go), it all works fine. I also extracted the code that calls the EJB from the servlet and I tested it in a small Java application, and it also works fine.
Things stop to work when I deploy my servlet in JRun or in Tomcat.
It appears that my code is correct, but the environment I try to run it is not, and I can't figure out what's wrong.
Can anyone help me?

Have you provided the environmental settings in the servlet.
It should be :
import oracle.aurora.jndi.sess_iiop.ServiceCtx;
env.put(Context.URL_PKG_PREFIXES, "oracle.aurora.jndi");
env.put(Context.SECURITY_PRINCIPAL, username);
env.put(Context.SECURITY_CREDENTIALS, password);
env.put(Context.SECURITY_AUTHENTICATION, ServiceCtx.NON_SSL_LOGIN);
InitialContext ctx = new InitialContext(env);
Object obj = ctx.lookup("test/EJBHome");
HomeObject home = PortableRemoteObject.narrow(
obj,"HomeObject.class");
RemoteObject remote = home.create();
This should make it work!!

Security problem accessing MBeanServer from a servlet
Hi,
I am trying to understand how WLS 7.0 secures a call to an MBean. Got the following
scenario:
- I am in a servlet context
- I have created and registered an MBean with the WLS MBeanServer. Fine so far
- Within the same call I can retrieve the MBean attributes. Fine so far
- I keep the MBeanServer reference in an object global to the servlet context
The problem:
- When I do another request and try to use the cached MBeanServer instance to
access the MBean, I get the following error:
weblogic.management.NoAccessRuntimeException: Access not allowed for subject:
principals=[], on ResourceType ...
Any idea?

AlainWhat ResourceType are you trying to access. From the Exception you're
trying to access it as an Anonymous user (principals=[]) and evidently
you're attempting to access something that is protected. I can't tell
what
from the snippet you've included.

Thanks Paul for your reply.
You are right. I can access my custom MBeans if I am authenticated for example
as an Administrator. My problem is that I want any application to access this
MBean authenticated or not. I am trying to find how I could grant permission to
this MBean to everyone. Still searching.
Thanks.
