WebObjects Java Client-JNLP fine on OS X and Linux, Windows problem

Hi,
I have been making a somewhat fruitful exploration into WebObjects Java Client development in order to get my nice IB interfaces for prototypes functional and deployed in a cross platform environment.
I have made some good strides in figuring out the semi-documented process of Java/IB integration, and how to build (including adding external libraries) and deploy onto a server (if anyone else is interested I will share; perhaps a blog is deserved), and though I am able to run it from both Mac OSX and Linux clients on the network (the Linux interface currently looks like garbage but will work on that), when I try to run it on windows I immediately get the following error tab in General:
An error occurred while launching/running the application.

It looks to me like the problem is with trying to rename the directory to a name with multiple periods, which works on UNIX but not on Windows. Is this a familiar problem? Is there any workaround/solution or any intent to fix?

Has the device always behaved this way? Did this start as a result of an update to the iOS software? If the problem is that bad, you should probably restore the iOS software and then restore from a backup. If that fails, restore as new and rebuild the device. If that fails, it's time for a trip to an Apple Store to let them have a look at the iPad.

How to call a text FTP proxy service from a Java client ?

Greetings,
I've configured a text FTP proxy service which downloads files from a FTP server. It pols a directory on the FTP server and, as soon as a file respecting a given pattern apears it is downloaded. I tested the service in the test console and by putting some test files onto the FTP server. Now, I need to be able to test it from a Java client. How may I do that ? I need to write a Java client to connect to the OSB and to tell to it to use the FTP proxy in order to download a given file, from a given location and to put it in a given location on the client machine. Many thanks in advance for any help. A sample would be great !
Kind regards,
Nicolas

Ok, I understand. The crucial question here is "what is a caller that you refer to?"
Don't get me wrong, but the problem here is that you probably don't understand, what OSB is good for. OSB is an event-driven system. The event in your case is a new message in remote FTP server. You have to define what should happen when that event is fired. And that's all. You don't have to involve other client (or caller) for this case.
You should define your FTP proxy to retrieve all relevant files from FTP server and then you should route them based on their name/content/encoding/whatever to different consumers. You can also have many proxies if you want - one for each name. It's up to you. But you don't have any "callers" in either case.

Looking up EJBs from a java client

While trying to migrate my application from standalone-oc4j
to Oracle Application Server 10g, I ran into the following problem.
My application has a stateless session bean. When trying to lookup the bean (from a java client), I get the following exception:
javax.naming.NamingException: Lookup error: javax.naming.AuthenticationException
Invalid username/password for UnifyoccEAR (ias_admin)
My code used the username/password I used to log into web-based console (which I used to deploy the application). The lookup code follows:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
OracleJASLayer.INITIAL_CONTEXT_FACTORY);
env.put(Context.PROVIDER_URL, "ormi://localhost:3201/UnifyoccEAR");
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, username);
env.put(Context.SECURITY_CREDENTIALS, password);
Context ctx = new InitialContext(env);
Object obj = ctx.lookup("unify/nxj/controlCenters/occ/ControlCenterEJB");
On a whim, I tried the old SCOTT/TIGER username/password and got the following
exception:
javax.naming.NoPermissionException: Not allowed to look up unify/nxj/controlCenters/occ/ControlCenterEJB,
check the namespace-access tag setting in orion-application.xml for details
So evidently, SCOTT/TIGER is in the security database used by the app (but isn't
authorized) while the ias_admin user is not in the security database.
I have the following questions:
1. In the default configuration, is there a username/password I can use to
lookup EJB homes in the jndi namespace of an OC4J instance? If so, what
is it?
2. Where is the security database? I tried looking in the web-based console
to find how to configure security and could not figure it out. I did find
the Security page for the application, but when I tried to add a user,
it had no effect. Furthermore, this page did not show a user entry for
SCOTT; hence, it doesn't seem that OC4J is actually using the information
on this page. This is strange because the path to this page is:
Farm > Application Server: ias_admin.lab10.sac.unify.com > OC4J: home > Application: UnifyoccEAR > Security
I then went to the Security page for the default application and found
that it did have a SCOTT user. So I added a new user and tried to run
my java client. This resulted in the javax.naming.AuthenticationException
described above (I was expected the NoPermissionException encounted when
using SCOTT/TIGER). Next, I used the Security page for the default application
to change the password for SCOTT and reran my java client using SCOTT/TIGER.
This time I was expecting an AuthenticationException exception, but got the
NoPermission exception. Therefore, it seems that OC4J isn't using this
security data either.
Hunting in the console (again) for the security database, I stumble accross
the Infrasturcture page and see an Identity Management section and see that
it is configure to use an Oracle Internet Directory server. Using
<ORACLE_HOME>/bin/oidadmin, I connect to the directory server and look
for the SCOTT user. I don't find it, so I believe that this can't be the
security database either.
3. Finally, how do I configure the OC4J instance such that it will allow
anonymous users to lookup my EJB from a java client?
Please help a confused and frustrated user.

Looking at your example, it looks like you are using a J2EE client container or some properties file to specify the JNDI environment used to create the initial context (for you use the no-arg constructor to InitialContext). Since our application needs to the ability to dynamically connect to ejb's running on different Java application servers (e.g., WebLogic, WebSphere, JBoss), such an approach will not work. Instead we must do it the old-fashioned way and pass the jdni connection info to the InitialContext constructor.
In any event, our problem isn't how to write the connection code, it is how to test it. Specifically, we can't figure out a valid username/password that will allow us to look up the home. Nor can we figure out how to configure security for the oc4j instance.

Unable to get 'InitialContext' using Java Client in Oracle App 10.0.2.0

Scenario & Problem Description: Unable to get 'Initial Context' using Simple Java Client in Oracle Application Server 10.0.2.0
I'm having an issue while I try to initialize the Initial Context for an EJB lookup from a simple Java Client [local lookup], but the same code snippet works fine when I try from Servlet. I have enclosed the Exception Stack Trace and the Code Snippet for your reference.

Note:
1. The user "ias_admin" & password "ias123" are the credential provided for the 'Admin' while installing the Oracle App Server and using these credentials I'm able to bring the Admin Console. Also, added new user 'guest/guest' - assigned this user to the 'admin' group ...
2. Since its a local lookup, there is no need to specify the credentials, but at runtime a dialog box pops up prompting to enter the 'userid/password' and when I enter the crendtials, I get the exception as stated. [In case of Servlet - EJB lookup, I'm not specifying any credentials]
Are there are any configuration parameters which I need to provide in any of the .xml? Could you please let me know the fix for the same.

I am able to successfully deployed my ejb on JBOSS but i m getting above error when i am trying to invoke ejb from java client.
kindly suggest me something to solve this issue.

Is it a remote lookup? Then maybe this will help:

Creating multiple stateful session beans from a java client. (EJB 3.0)

I'm having difficulties with the following:
To access the ShoppingCartBean, I have to put the following annotation in my standalone java client:
@EJB
private static ShoppingCartRemote shoppingCartBean;
The static must be there, thus only one ShoppingCartBean will exist within my java client. But as the ShoppingCartBean is a stateful session bean, I want to be able to get different beans of the same type.
What is the correct way to do this in EJB 3.0?

Great question. Because Home interfaces have been removed for the EJB 3.0 simplified
API, stateful session bean creation happens as a side-effect of injection. However, the
same is true of EJB 3.0 business interface lookups. The easiest way to create additional
stateful session beans is to lookup the same dependency that was declared via your
@EJB annotation.
E.g.,
// Assuming the declaring class is pkg1.ShoppingCartClient.java
InitialContext ic = new InitialContext();
ShoppingCartRemote scr1 = (ShoppingCartRemote)
ic.lookup("java:comp/env/pkg1.ShoppingCartClient/shoppingCartBean");
Note that the name relative to java:comp/env is the default associated with your
@EJB annotation since the name() attribute wasn't used. Alternatively, you
could have used :
@EJB(name="scb") private static ShoppingCartRemote shoppingCartBean;
InitialContext ic = new InitialContext();
ShoppingCartRemote scr1 = (ShoppingCartRemote) ic.lookup("java:comp/env/scb");
Yet another alternative is to declare the @EJB at the class-level. This just defines
the dependency without any injection, which is fine if you want to create a bunch of
them via lookup anyway.
@EJB(name="scb", beanInterface=ShoppingCartRemote.class)
public class .... {

How to deal with credentials for external applications using a Java Client/

Hi Guys,
This is the case. I am integrating an external application with an ADF Application. I have implemented some programmatic ViewObjects that are being filled up by a REST Java Client Wrapper. Everything is working fine but the issue is that the credentials the wrapper is using are hard coded inside the java class. I am thinking to ask for the credentials at the beginning of my taskflow and then store them somewhere and use them then to create my client wrapper (passing them in the constructor).
However, I don't know if my approach is good and I would like you to share your experiences or how to deal with this.
Regards

You can use Credential Store Framework to store the credentials securely in the weblogic server instead of hardcoding in the java class.
The Credential Store Framework:
- enables you to manage credentials securely
- provides an API for storage, retrieval, and maintenance of credentials in different back-end repositories
Check the documentation on CSF API -
http://docs.oracle.com/cd/E29505_01/core.1111/e10043/devcsf.htm
Major Steps -
1. Create a credential map and key in em console to store the password (http://docs.oracle.com/cd/E25054_01/core.1111/e10043/csfadmin.htm)
2. Use CSF API to retrieve the stored password
3. In jazn-data.xml give permissions to access CSF key and map

Java clients and IUserPrincipal class not working for authentication

I'm developing a Java client which talks to EJBs on the iAS server via
iiop.
I've already developed EJBs, and they work fine. I'm trying to do user
authentication per the examples in the Rich Client section.
Here are the steps I've taken:
1. I've created a class (achp.security.AchpPrincipal) which implements
com.netscape.ejb.client.IUserPrincipal.
2. I've added the class to the initial context via the following line:
env.put("com.netscape.ejb.client.PrincipalClass",
"achp.security.AchpPrincipal");
3. I do a home lookup with the above initial context when the
application starts, create a bean, and then invoke a method on the bean.
When I do the home lookup, according to the manual, my AchpPrincipal
class should be instantiated (which brings up a login window which then
records username and password for future use).
This never happens. The AchpPrincipal class is never instantiated,
although the home lookup occurs successfully and the bean method call is
also performed successfully.
I'm running server on my Win2K desktop, with SP3. And, of course, I've
properly installed the CXS server (as indicated by the fact that I can
communicate with the EJBs at all though the Java client).
Any help would be appreciated.
Thanks,

Java Client throws exception while sending NTLMV2 Response from WIN7 to W

We have written a Java client which connects to a webservices application using NTLM authentication against Windows 2008 R2 Server (using IIS7). This program works fine when running from Windows XP, Linux but failing when running from Windows 7.
Error encountered is: java.io.IOException: Authentication failure.
Here is what we have written to connect to HTTPS with credential using SSLContext as mentioned below.
SSLContext sc = SSLContext.getInstance( "SSL" );
sc.init( null, trustAllCerts, new java.security.SecureRandom() );
HttpsURLConnection.setDefaultSSLSocketFactory( sc.getSocketFactory() );
( ( HttpsURLConnection )( m_oHttpURLConnection ) ).setHostnameVerifier( this );
URL url = new URL("https://testsite...");
HttpsURLConnection m_oHttpURLConnection = (HttpsURLConnection) url.openConnection();
Following properties are set to HttpsURLConnection:
RequestMethod : GET
InstanceFollowRedirects : true
AllowUserInteraction : true
UseCaches : false
DoOutput : true
DoInput : true
After setting all the above parameters the following code is used to set credentials data and connect to site
Authenticator.setDefault(new MyAuthenticator ());
m_oHttpURLConnection.connect();
After connection is successful request XML is sent to server and expecting a response from the server. So when the below line is called exception is thrown.
m_oHttpURLConnection.getResponseCode();
Exception :
java.io.IOException: Authentication failure
     at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1173)
     at java.net.HttpURLConnection.getResponseCode(HttpURLConnection.java:373)
     at sun.net.www.protocol.https.HttpsURLConnectionImpl.getResponseCode(HttpsURLConnectionImpl.java:318)
After changing LAN Manager Authentication level setting of Windows 7 from Send NTLMv2 response only to Send LM & NTLM use NTLMv2 session security if negotiated, application is working fine.
Local Security Settings àSecurity SettingsàLocal Policies à Security Optionsà Network security: LAN Manager Authentication level
By default in Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2: Send NTLMv2 response only , Lowering the security level at the client end is bit risk and typically is not recommended.

this subforum is about Kerberos and GSS and not about NTLM. Why are you hasseling with NTLM? Take Kerberos.

Using Portable datasource lookup for a java client in OC4J 10g

Hi,
I'm in the process of porting a standalone java client to j2ee. At the moment I have a thick java client which uses jndi to access a global datasource configured on the OC4J server (10.1.2.0.2) and it works fine.
Using the 'Services Guide' I decided the next step was to deploy the client as a J2EE application. At the moment the j2ee application only contains the descriptors (i.e application-client.xml and orion-application-client.xml packaged under META-INF in a .jar. This is, in turn, packaged in an .ear along with application.xml (again under META-INF.)
This is where I'm hitting problems. The following config produces a 'javax.naming.NameNotFoundException' error
application.xml
<application>
     <display-name>appName</display-name>
     <description>appDescription</description>
</application>
application-client.xml :-
<application-client>
     <display-name>appName</display-name>
     <resource-ref>
          <res-ref-name>jdbc/MaptoTest</res-ref-name>
          <res-type>javax.sql.DataSource</res-type>
          <res-auth>Container</res-auth>
     </resource-ref>
</application-client>
orion-application-client.xml :-
<orion-application-client>
     <resource-ref-mapping name="jdbc/MaptoTest" location="jdbc/Test"/>
</orion-application-client>
jndi.properties :-
java.naming.factory.initial=com.evermind.server.ApplicationClientInitialContextFactory
java.naming.provider.url=opmn:ormi://<machine>:6004:<OC4J_INSTANCE>/appName
java.naming.security.principal=<USERNAME>
java.naming.security.credentials=<PASSWORD>
client.class
ctx = new InitialContext();
ds = (DataSource)ctx.lookup("java:comp/env/jdbc/jdbc/MaptoTest"));
"jdbc/Test" was configured through OAS and is present in data-sources.xml (it is the ejb-location property).
I'm running the client through Jdeveloper. I've used SJSAS previously and was use to configuring and deploying a application module through it's own tool. SJSAS also has a tool (appclient) for running the client. Is there something similar I should be using in OC4J?
The services guide only mentions web.xml and ejb-jar for portable datasource lookup but I assume it's also possible using application-client.xml.
It seems to me that my descriptors don't mention the j2ee application explicitly. Am I missing an entry in one of the xml descriptors. Any help would be appreciated this is driving me crazy!
Thanks in advance for any advice.

Hi Geoff,
The configurations for your client.xml files look ok. Question: where did you configure the datasources.xml i.e. under j2ee/<OC4J_Name>/config or under the application-deployments/<appname>, kindly check and let us know.
Thanks,
Deepak

Help required for ---- Java Client -- XI -- R/3

Hello,
*My Java Client is on Server A. My XI is on server B. I had wsdl (webservice) with me .*
How to call wsdl (webservice) from Java Client that is on Server A to XI that is on server B.
Pls help
Regards

Good Morning Prateek,
I have tested with Altoval XML spy . It is working fine.
Altoval XML spy (on my local machine) -- XI -- R/3.
Now instead of xml spy I want java client -- XI -- R/3 with scanerio that javal client is on server A and XI on server B.
2. For that request parameter (O/B Interface) I have made wsdl (webservice) through XI .
After making wsdl it ask to save that wsdl.I have saved that wsdl currently
in my local machine.
3.How to call this wsdl (webservice) from Java Client that is on Server A to XI that is on server B.
Pls explain me the all the steps in detail and also send me links/docs for it.

Java client failing to connect to web service - help!!

Hi
I have created a Web service using ASP Web Matrix, which currently resides on my C drive in c:\Service6\HelloWorld.asmx.
The service can be tested from a browser on my local machine by calling: http://localhost/Service6/HelloWorld.asmx. This works fine, i.e. it takes a string as a parameter and returns an amended string.
When I try to access this from a Java client I created in Netbeans, however, I get the following error message:
Server did not recognize the value of HTTP Header SOAPAction: sayHiya.
at System.Web.Services.Protocols.Soap11ServerProtocolHelper.RouteRequest()
at System.Web.Services.Protocols.SoapServerProtocol.Initialize()
at System.Web.Services.Protocols.ServerProtocolFactory.Create(Type type, HttpContext context, HttpRequest request, HttpResponse response, Boolean& abortProcessing)
Can anyone advise what I am doing wrong?
[nb. I have spent over a week trying to sort this, so I have tried!!)
The code for the client follows:-
// The Axis package is used to generate and handle the SOAP call
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
import org.apache.axis.encoding.XMLType;
// The rpc package is used to create the RPC call
import javax.xml.namespace.QName;
import javax.xml.rpc.NamespaceConstants;
// The java.net package gives a URL class
import java.net.URL;
public class HelloWorldClient {
/** Creates a new instance of HiyaClient */
public static void main(String[] args)
try
String endpoint = "http://localhost/Service6/HelloWorld.asmx";
Service service = new Service();
Call call = (Call) service.createCall();
// Configure the call
call.setTargetEndpointAddress(new URL(endpoint));
call.setSOAPActionURI("sayHello");
call.setEncodingStyle(NamespaceConstants.NSURI_SOAP_ENCODING);
call.setOperationName(new QName("urn:HelloWorld", "sayHello"));
//call.setReturnType(XMLType.XSD_STRING);
System.out.println("**Works to here**");
//Invoke the call
String result = (String) call.invoke(new Object[] { "Diane" });
System.out.println("Sent 'Diane', got '" + result + "'");
catch(Exception e)
System.err.println(e.toString());

Hiya, did try that - tried
"http://localhost:8080/HelloWorld.asmx" and
"http://localhost:8080/Service6/HelloWorld.asmx" and it still didn't work.
Thanks anyway.
Anyone else got any bright ideas?
