Error during JNDI lookup Accessing Remote EJB (access to web service restricted using declarative security model)

Hello everyone,
I developed a Web Service prototype accessing remote EJB using the EJB
control with special syntax in the jndi-name attribute: @jws:ejb
home-jndi-name="t3://10.10.245.70:7131/AccountDelegatorEJB"
Everything works fine, but I get an error when I restrict access to my web
service with a declarative security model by implementing steps provided in
help doc:
- Define the web resource you wish to protect
- Define which security role is required to access the web resource
- Define which users are granted the required security role
- Configure WebLogic Server security for my web service(Compatibility
Security/Users)
I launch the service by entering the address in a web browser. When prompted
to accept the digital certificate, click Yes, when prompted for network
authentication information, enter username and password, navigate to the
Test Form tab of Test View, invoke the method by clicking the button and I
get the following exception:
<error>

I have a simple Hello method as well in my WebService (which is also
restricted) and it works fine, but remote EJB access doesn't. I tested my
prototype on Weblogic 7.2 and 8.1 platforms - same result.
Is that a bug or I am missing some additional configuration in order to get
that working. Has anyone seen similar behavior? Is there a known resolution?
Or a suggested way to work around the problem?
Thank you.

Andre,
It would be best if this issue is handled as an Eval Support case. Please
BEA Customer Support at http://support.beasys.com along with the required
files, and request that an Eval support case be created for this issue.
Thanks

Note: inter-domain communication is configured properly. The Web Service to
remote EJB works fine without a declarative security.
Any other ideas?

Andre,
It seems you are using the URL
jndi:t3://secuser1:[email protected]:7131/AccountDelegatorEJB
whereas you should not be specifying the "t3:" protocol.
The URL should be like
jndi://secuser1:[email protected]:7131/AccountDelegatorEJB
Please do let me know if you see any issues with this.
Note that this will only allow you to access remote EJBs in the same WLS
domain. For accessing EJBs on another domain, you need to configure
inter-domain communication by
following a few simple steps as mentioned at
http://e-docs.bea.com/wls/docs81/ConsoleHelp/jta.html#1106135. This link has
been provided in the EJB Control Workshop documentation.

Anurag

Anything else should I try?
P.S. AccountDelegatorEJB, the remote EJB my Web Service calls is NOTaccess
restricted.
I hope there is a solution.

Andre,
Can you try using the following url with username and password
jndi://username:password@host:7001/my.resource.jndi.object ?
once you add webapp level security, the authenticated is the user who
invokes the EJB.
http://e-docs.bea.com/workshop/docs81/doc/en/workshop/guide/controls/ejb/con
CreatingANewEJBControl.html?skipReload=true
has more info on using remote EJB's.
Hope this helps.
Thanks

Servlet jndi lookup to remote EJB, servlet and EJB not in the same application

Hi,
I think that the subject explain my problem.
I have Oracle IAS9i 9.0.2.0.0, and JDeveloper 9.0.2.829
I have deployed and EJB in IAS9i and i want to use from the developer machines, which have JDeveloper.
how can i to do remote calls from JDeveloper?.
I have modifed the orion-application.xml, and added remote=true.
I have modifed the rmi.xml and added the hosts where the Jdeveloper placed.
Any ideas?
Thanks and cheers
P.D The app server and jdeveloper are in the same net.

Steps to access a remote EJB from within OC4J
++++++++++++++++++++++++++++++++++++++++++++++
1) Deploy EJB application (ApplicationRemote) to remote container (REMOTE)
"java -jar admin.jar -deploy ormi://REMOTE.hostname:REMOTE.port REMOTE.username REMOTE.password -deploy -file ApplicationRemote.ear
-deploymentName ApplicationRemote"
2) Ensure that local application (ApplicationLocal) has ejb-ref tags for remote EJBs accessed (in web.xml or ejb-jar.xml)
3) Deploy to local container (LOCAL) an empty application (ApplicationEmpty) with the same name as the remote application (ApplicationRemote)
"java -jar admin.jar -deploy ormi://LOCAL.hostname:LOCAL.port LOCAL.username LOCAL.password -deploy -file ApplicationEmpty.ear -deploymentName
ApplicationRemote"
5) Deploy local application (ApplicationLocal) to local container (LOCAL)
"java -jar admin.jar -deploy ormi://LOCAL.hostname:LOCAL.port LOCAL.username LOCAL.password -deploy -file ApplicationLocal.ear -deploymentName
ApplicationLocal"
4)Restart local container
ApplicationEmpty should consist of just an application.xml file - no modules. The same file can be deployed with different application names for all the remote
applications that must be accessed.
ApplicationLocal should access the remote EJB by using the following JNDI properties
java.naming.factory.initial = "com.evermind.server.rmi.RMIInitialContextFactory"
java.naming.provider.url = "ormi://REMOTE.hostname:REMOTE.port/ApplicationRemote"
java.naming.security.principal = "REMOTE.username"
java.naming.security.credentials = "REMOTE.password"

Access Enterprise Search via ABAP Web Service

Hello ES experts,
I am looking for more information on how to access Enterprise Search via ABAP web service QSDispatcher, using processQuery operation. I created a client proxy and need information on structure of input and output parameters (query and query result)
Thanks, Srdjan

Hi Srdjan
You can access the SAP ABAP system by configuring it in the NW ES admin console, any system with version > 4.6C can be integrated in the search engine.
The UI for NW ES is a WebDynpro via Web Browser (In the future will be integrated in Widgets and Portal, etc) but i'm not sure if you want to use the WS to access the results of the ES searching or if you want to integrate a WS from ABAP as part of the searching area...
Please clarify.
Thanks,
Best Regards,
Luis

EJB exposed as web services

I am very new to web services.
I understand that a Stateless bean can be exposed using RPC style web services.
But I want to know if a stateless session bean can be accessed by EJB client and Web service client (java or non-java) simultaneously. ?
i.e. 1. Can same bean serve two types of client simultaneously.(java and non-java client)
2. Does this web service accept complex java object as input parameters. and how?

Hi Patrik,
> Exception raised from invocation of public void com.sap.sia.serviceMonitor.ServiceMonitorBean.initPostConstruct() method on bean instance com.sap.sia.serviceMonitor.ServiceMonitorBean@5a8ab489 ... ; nested exception is: java.lang.NullPointerException
The NPE occurs in the bean code, in the initPostConstruct() method or some other method it calls. Unfortunately, its stack trace is not available above, but you should be able to find it in the defaultTrace file.
HTH!

Please help. The problem does not occur with Integrated WLS. I think the config scripts are correctly running from JDev.

Hi,
It's not easy to tell what's wrong with your example.
Maybe you could send me a zip and I'll check when I have some time.
By the way, you're asking a question about the lookup of an EJB3, I wrote an article that covers that topic.
It should give you some interesting input.

Security issue to access remote ejbs, URGENT!!! please and thanks.

Hi gurus:
I have questions for you. I need to access remote ejbs. the ejb(beans) have been
deployed on remote machine. I have helper class file to do JNDI lookup to point
the machine and find it.
I have local machine to have all of home interfaces, remote interfaces and stub
classes and common classes. I have local jsp and config weblogic-web.xml to allow
test user to access.
Sometimes fine but got the following message and error from my local machine.
I have no clue about that. Is any other issue that remote machine have security
to limit clients to access beans. Because remote wl server startup as system/weblogic.
If my local machine startup as system/weblogic too. It has no problem at all.
This doesn't make sense for my local machine has to have same system's password
as remote machine. Should have some issues to limit clients to access remote beans.
Thank you for any helps and suggestions in advance.
Steven.

well, if we post in other threads, they tell me that it is ARD and server technology. If you try to post back to my mac in the normal threads about Leopard, they point us to this thread.
It seems that a lot of people are frantically looking for someone who can explain in plain english how to do the remote desktop - is remote desktop the same technology as back to my mac?
Extremely frustrating for people like me who don't have unix or programming language experience... We choose for mac because we wanted user friendlyness... What a joke!

Unable to open connection to MS Access 2013 .accdb file Under WCF Web Service Project Using Windows 8.1 64bit

I am encountering the following error when trying to connect to an Access 2013 database:
The 'Microsoft.ACE.OLEDB.12.0' provider is not registered on the local machine.
I have Visual Studio 2013 SP3 running on Windows 8.1 64bit OS which also has Office 2013 installed (which includes MS Access 2013). My project is a WCF web service using .NET Framework 4.5.1 using any cpu as target. I have tried reluctantly
to install the older drivers as described by in the below article:
https://social.msdn.microsoft.com/Forums/en-US/1d5c04c7-157f-4955-a14b-41d912d50a64/how-to-fix-error-the-microsoftaceoledb120-provider-is-not-registered-on-the-local-machine?forum=vstsdb
and also went through the "Add Data Source" wizard in the Project menu to have the connect string automatically built. Even with the automatically built connect string I can not connect to the .accdb file from within my WCF web service.
What's odd is if I use the Database Explorer in Visual Studio it has no problem connecting the my Access file. I inspected the connect string and tried to use it as well but still get the same error. Even stranger is that I have no problem connecting
to the Access DB in an ASP.NET project on the same PC. I am also able to connect to the Access file using a simple Windows Forms application. So I'm wondering if it has something to do with trying to connect to the Access file from a WCF web service
project.
What I'd like to know is if anyone has been able to get this to work in an environment as I described above as a 64bit WCF web service project? I tried to switch my project to 32bit but when I do I get a different error which reads:
System.BadImageFormatException: Could not load file or assembly 'file:
Almost to the point of trying to get this web service project done with SQL Express but would like to know if it can be done with MS Access 2013. Any information anyone can provide to help me get past this issue is greatly appreciated. Thanks.

Have you installed the 64-bit Access driver on your machine? See
Data Source Names and 64-Bit Operating Systems for the differences in odbcad32. Call %SystemRoot%\system32\odbcad32.exe to check the drivers.
How do you host your service? Stand-alone or IIS or embedded to another application? Keep in mind that IIS7 runs it in its application pool which is defaullt 64bit. Thus the bad image exception, when compiling your service as 32bit.
When you need the Access database for your service to store informtation, then I would switch to SQL Server (Express) or XML files depending on your actual needs.
Also check whether your account under which your service is run has the necessary NTFS file permissions on the access file and the folder. This is getting even more complex when it's a remote folder.

Test web service proxy using EJB session bean client...

Hello!
I am following this blog /people/abdelmorhit.elrhazi/blog/2009/10/30/how-to-consume-an-inbound-backend-web-service-in-nwdsjboss-environment to create a EJB session bean client to access the web service proxy...
The blog is not very clear. Where should I be deploying the web service proxy and the EJB session bean (web service client) ? on the PI 7.1 ?
How to find out the URL for the wsdl ?
Thanks

> The blog is not very clear. Where should I be deploying the web service proxy and the EJB session bean (web service client) ? on the PI 7.1 ?
"To deploy your web service proxy and session bean, right click on your JBoss server in the Servers view, and click on Add Remove Projects, add you ear file and click finish."
You need a JBoss server.

EJB 3.0 Web Service

Hi!
I tried to create a Web Service (through wizard) from existing EJB 3.0 Session Bean. Basicly, the wizard just added @WebService annotation to my existing code...
Now, the problem is that simple methods like:
@WebMethod
public String helloWorld() {
return "Hello World!";
}works fine. Expect that if I use Local Interface for this Session Bean, the WSDL shows two helloWorld methods (and one is with exclamation icon showing some kind of problem with multiple methods with same name - but it is not true, I have one and the other one is just interface).
But, when I want to expose my real business service methods like:
@WebMethod
public List<Employee> getEmployees() {
return (List<Employee>)q.getResultList();
}it doesn't work (the Web Service create wizard finishes ok but service doesn't work)! When I try "Test Web Service" (from Session Bean context-menu) or "Show WSDL for Web Service annotations" the error is thrown (Null pointer exception in WSDL).
Basically, it looks to me that Web Service cannot use EJB Entities as parameters or results. Is this correct? I saw some examples on EJB 3.0 web services and there are entities routinely used as both input and output parameters.
Can someone, please, explain me what I'm doing wrong here.
Thanks in advance,
Pedja
P.S. In Web Service wizard, only SOAP 1.1 is enabled. How can I choose SOAP 1.2? And what EJB 3.0 bindings are in same context (SOAP 1.2 or EJB 3.0 bindings?)?

Hi Frank,
Most of those problems are resolved (NPE was due to Timestamp field, and two methods with the same name in WSDL because of not choosing to generate SEI in wizard, so the generated WSDL had one method from the Session bean and the other from it's Local interface). But, the errors should DEFINITELY be more descriptive.
Does the wizard work correctly? I noticed plenty of "bug like" details. For example, if I choose to create asynchronous web service, later when I go to Properties the "Asynchronous Web Service" checkbox isn't checked. Also, the @WebMethod annotations are sometimes generated and sometimes not (even if the method is checked to be exposed).
I am also getting these exceptions when I create a proxy for the asynchronous web service (I selected "Generate asynchronous methods for all operations"), could be I'm doing something wrong:
WARNING: The parameter/return type "java.util.concurrent.Future" in the method
"public abstract java.util.concurrent.Future<?>

Errors installing web service to use dreamweaver extension

Portal Version: 10g
OS/Vers. Where Portal is Installed:: Linux AS 2.1
Errors installing web service to use dreamweaver extension
Recently I download the dreamweaver extension for portal, but when I try to install it several errors are raised... in the installation guide the next message appear:
This installation for this feature is an easy 3 step procedure.
1. Installing the Portal web service
2. Configuring the web service to work with your portal (one time administrative process)
3. Installing the PortalTemplates extension for Dreamweaver MX
well but when I try to run the 1 step everything goes wrong...
in the guide say:
# Transfer this file to the OC4J_HOME/j2ee/home directory of the OC4J
(please make sure that the OC4J is up and running)
# Use the following command to install the web service
java -jar admin.jar ormi://<oc4j_host>:<oc4j_ormi_port>
<username> <password>
-deploy -file portalTemplate.ear -deploymentName portalTemplate
here it's where I have some questions,
1. the ormi referers to the rmi ok (I think that), well then I go tho the iasconsole and search for the ports and is show:
home RMI 3202
OC4J_Portal RMI 3203
OC4J_BI_Forms RMI 3204
then I use the home-> port 3202
java -jar admin.jar ormi://myhost.midtierinstall.com:3202
ias_admin ias_midtier_admin_password -deploy -file portalTemplate.ear -deploymentName portalTemplate
but the following messages appear :
Error: Unable to find java:ServerAdministrator : lookup error:javax.naming.AuthenticationException invalid username/passwod for default (ias_admin).... and the error continue... but the problem is that the password works when I use the enterprise manager in that midtier console...
I want to know if I'm doing something wrong or how I should use this command to install that web service

The ormi is the rmi port in the OC4J. This coold be found in oc4j_home/j2ee/home/config/rmi.xml file. The default port is 23791.
Hope this helps,
Ramya

Adding new Remote System unavailable in Web Service Request

Hi,
I created a CRUD Web service from a table using web service generator.I added a new remote system to the repository.When I invoke the create operation (which has key mapping "Yes"),it says "Remote System not found in the repository"
I am able to view the Remote System via Data Manage though.
Any ideas?
Regards,
Premjit

Hi Premjit,
When did you added new remote system?
Before generating web services.
Or After generating web services.
If you have added remote system after generating web services.
Then try re-generating web services using web service generator.

Errors creating a Web Service Proxy using Microsoft WSDL.exe tool

I have deployed a BPEL process using JDeveloper. This process can be invoked from the BPEL console and completes as expected. I am trying to create a Web Service Proxy using the Microsoft WSDL.exe tool so that the process can be invoked from a Microsoft Word document. This process is based on the AutoLoan example in the Developer's Guide for Microsoft Office Interoperability B25781-01.
WSDL.exe returns the following error message
Error: There was an error processing 'http://erp.template.co.uk:8889/orabpel/default/HonorariumSmartDoc/1.0/HonorariumSmartDoc?wsdl'.
- The document at the url http://erp.template.co.uk:8889/orabpel/default/HonorariumSmartDoc/1.0/HonorariumSmartDoc?wsdl was not recognized as a known document type. The error message from each known type may help you fix the problem:
- Report from 'WSDL Document' is 'There is an error in XML document (19, 7).'.
- A schema with the namespace '' has already been added.
- Report from 'DISCO Document' is 'Discovery document at the URL http://erp.template.co.uk:8889/orabpel/default/HonorariumSmartDoc/1.0/HonorariumSmartDoc?wsdl could not be found.'.

How do I resolve this error?

Hi,
The error message said
the Permission(java.lang.RuntimePermission getClassLoader) has not been granted to USF.
I'd follow the suggestion
The PL/SQL to grant this is dbms_java.grant_permission( 'USF','SYS:java.lang.RuntimePermission', 'getClassLoader', '' )
