Exceptions arsing while accessing DataSource from a stand alone java clie

Dear all responders,
can any one help in resolving my problem??the problem description is as follows:
i am using sun one application server 7.0 to deploy a J2EE Apllication
so i have created a data source using the admin page with the name
"nodbsession".now i want to access this datasource using a stand alone java client and want to establish a connection to database.i am using the following code snippet to do so
**code is as follows**
Hashtable env=new Hashtable();
               env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
               env.put(Context.PROVIDER_URL, "iiop://localhost:3700");
               System.out.println("creating context");
               Context ctx =new InitialContext(env);
                              System.out.println("created successfull");
               DataSource ds =(DataSource)ctx.lookup("nodbsession");
/* by using like this also it is not working
DataSource ds =(DataSource)ctx.lookup("java:comp/env/jdbc/nodbsession");
i am able to obtain the context succussfully but the exception is thrown for the data source look up
the following exception is thrown
javax.naming.NameNotFoundException. Root exception is org.omg.CosNaming.NamingContextPackage.NotFound: IDL:omg.org/CosNaming/NamingContext/NotFound:1.0

please help me in resolving the above problem
advance thanx to all those who intend to reply
please provide me a proper resolution

I think the appserver uses com.sun.enterprise.naming.SerialInitContextFactory on the server side to register different resources. Anything registered with SerialialInitContextFactory cannot be resolved with a CNCtxFactory.
Can you try using SerialInitContextFactory on the client side.

Calling a web service from a stand alone java class

I need to invoke a web service from stand alone java class- Please let me know how to acheive this.

Hi jazz123,
There's an example in the [*Java Web Services Tutorial*|http://java.sun.com/webservices/docs/2.0/tutorial/doc/] : see Chapter 1: Building Web Services with JAX-WS - A Simple JAX-WS Client.

Problem while calling a Webservice from a Stand alone java program

Hello Everyone,
I am using a java program to call a webservice as follows. For this I have generated the client proxy definition for Stand alone proxy using NWDS.
Now when I call the method of the webservice I am getting the correct result but along with the result I am getting one error and one warning message in the output.
The java code to call the webservice is as follows.
public class ZMATRDESCProxyClient {
     public static void main(String[] args) throws Exception {
          Z_MATRDESC_WSDService ws = new Z_MATRDESC_WSDServiceImpl();
          Z_MATRDESC_WSD port = (Z_MATRDESC_WSD)ws.getLogicalPort("Z_MATRDESC_WSDSoapBinding",Z_MATRDESC_WSD.class);
          String res = port.zXiTestGetMatrDesc("ABCD134");
          System.out.print(res);
The result I am getting is :
Warning ! Protocol Implementation [com.sap.engine.services.webservices.jaxrpc.wsdl2java.features.builtin.MessageIdProtocol] could not be loaded (NoClassDefFoundError) !
Error Message is :com/sap/guid/GUIDGeneratorFactory
<b>Material Not Found</b> -
> This is the output of webservice method and it is right.
Can any one please let me know why I am getting the warning and error message and how can I fix this.
Thanks

Hi Abinash,
I have the same problem. Have you solve that problem?
I am using a java program to call a webservice too. And I have generated the client proxy definition for Stand alone proxy using NWDS. When I call the method of the webservice I am getting the correct result but along with the result I am getting one error and one warning message in the output.
The java code to call the webservice is as follows.
MIDadosPessoaisSyncService service = new MIDadosPessoaisSyncServiceImpl();
MIDadosPessoaisSync port = service.getLogicalPort("MIDadosPessoaisSyncPort");
port._setProperty("javax.xml.rpc.security.auth.username","xpto");
port._setProperty("javax.xml.rpc.security.auth.password","xpto");
String out = port.MIDadosPessoaisSync("xpto", "xpto");
System.out.println(out);
The result I am getting is :
Warning ! Protocol Implementation [com.sap.engine.services.webservices.jaxrpc.wsdl2java.features.builtin.MessageIdProtocol] could not be loaded (NoClassDefFoundError) !
Error Message is :com/sap/guid/GUIDGeneratorFactory
<b>The result of the WS is correct!!!</b>
The Java project does not have any warning. But the stand alone proxy project has following warnings associated with it.
This method has a constructor name     MIDadosPessoaisSync.java
The import javax.xml.rpc.holders is never used     MIDadosPessoaisSyncBindingStub.java
The import javax.xml.rpc.encoding is never used     MIDadosPessoaisSyncBindingStub.java
The constructor BaseRuntimeException(ResourceAccessor, String, Throwable) is deprecated     MIDadosPessoaisSyncBindingStub.java
It is very similar with your problem, could you help me?

Call a Servlet via POST from a Stand alone Java App

Hi guys.
Right now I am facing a tricky problem I hope you can help me on this...
What I want to do is to call a servlet that is listening ( I can't touch the servlet code) in a web browser.
I was able to send a GET request by a code like this:
URLConnection conn = new URL(webServerStr).openConnection();
conn.setDoOutput(true);
OutputStreamWriter wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(webServerStr);
wr.flush();
and everthig was all right.
The problem arises when I try to send a long REQUEST via my java app. I get a 414 HTTP error (414 - Request-URI Too Large ). When I do the long request by browser works fine. (when I fill all the form and press the submit button)
The only difference between the browser request and my java request is the ACTION. From the FORM is POST and when I build the string to send it out to the web server is via GET ( I build the string like ?ATTR=VALUE&ATTR2=VALUE2....)
Here is my question. How I do a POST request from a java application?
Any ideas?
Thaks guys and any help will be appreciate.

URL url = new URL("http://localhost:8080/");
HttpURLConnection con = (HttpURLConnection)url.openConnection();
con.setStuff(...............................check out api
con.setDoOutput(true);
con.connect();
// write stuff
PrintWriter pw = new PrintWriter(con.getOutputStream());
pw.println(depart);
pw.flush();
pw.close();
// read reply
BufferedReader br = new BufferedReader(new InputStreamReader(con.getInputStream()));
String res = br.readLine();

You didn't post the stack trace from the server, but I'm guessing it's complaining about the QName class. Sun changed the QName class in JDK 1.5 wreaking havoc on JDK 1.5 clients that use JDK 1.4 servers and attempt to pass a QName object from one to the other. If your client uses JDK 1.5, your sever will need to use a QName class which is compatible. The file liquiddata/lib/wls90interop.jar contains a QName class that is compatible with the one in JDK1.5. You can put it first in the classpath of your server.
If you already have wls90interop.jar first in the classpath of your server, then, for your client, you need to either (1) use the Sun JDK 1.5; or (2) put wls90interop.jar first in the classpath of your client (if you are running JDK 1.4).

Error in obtaining token using TokenManager thru a stand-alone java appln

I am trying to use the IS Java APIs to connect to the directory server and insert a user in the directory from a stand alone java appln.
I get an SSOException while trying to obtain a Token object from the TokenManager (TokenManager.createSSOToken() method ).
Following is the dump of the error:
Exception Message: LDAP authentication failed.
com.iplanet.sso.SSOException: LDAP authentication failed.
at com.iplanet.sso.providers.dpro.SSOProviderImpl.createSSOToken(SSOProv
iderImpl.java:94)
at com.iplanet.sso.SSOTokenManager.createSSOToken(SSOTokenManager.java:2
57)
at SampleUserOperations.main(SampleUserOperations.java:51)
However, the principal and password supplied in the code are correct. Following is the code that generates this error.
public static void main(String[] args)
          int count = 0;
          SSOTokenManager Manager = null;
          SSOToken Token = null;
          AMStoreConnection AMConn = null;
          try
               //create a token
               Manager = SSOTokenManager.getInstance();
               System.out.println("Got a token mgr");
               Token = Manager.createSSOToken(new AuthPrincipal("uid=admin,ou=administrators,ou=topologymanagement,o=netscaperoot"), "abcdefg123");
                              System.out.println("Got a token");
               AMConn = new AMStoreConnection(Token);
               System.out.println("Got a conn");
          catch (com.iplanet.sso.SSOException e)
               count++;
               System.out.println("COUNT = " + count + " : " + e);
The credentials provided in the code are correct. What could be the cause of the error?
TIA,
siddharth.

Tthis class is undocumented and this is the reason why you will not find any documentation. This is not the correct way for a client to authenticate to the is in v6. You need to use the JAAS API. I do not believe that the AuthPrincipal sample works in 6.
The package for the class is com/sun/identity/authentication/internal/

How to access my application on a SunOne 8.0.0_01 from a stand-alone client

Hello,
perhaps someone of you knows how can solve my problem accessing my J2EE-Application with EJBs, etc. from a stand-alone client.
In the classpath of my client the appserv-rt.jar and j2ee.jar are accessible. In the sourcecode I tried to access the server with:
Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
env.put(Context.PROVIDER_URL, "iiop://myserver:3700");
Context initialContext = new InitialContext(env);

Did your stand-alone client on the remote machine encounter the same error as your tomcat attempt? Try looking in the tomcat log for a more detailed stack trace.
I'm able to do this from tomcat 5.0 on a remote machine with JDK 1.5 and the latest version of the J2EE 1.4 SDK release (AS 8.2) for an appserver running on linux or solaris. You might want to try with those versions as well.

Error while creating datasource from table MBEWH

Hi all,
I am facing an error message while creating datasource from table MBEWH
"Invalid extract structure template MBEWH of DataSource "; This operation failed, because the template structure quantity fields or currency fields, for example, field LBKUM refer to a different table.
Can anyone help me that why system is not allowing me to generate generic datasource for table MBEWH to transfer my month wise inventory data.
thanks and regards.

Hi Zakir,
      This was comming for classification data... when ever you want to extract some classification related data then we can't create generic datasources directly.. for that you need to go with CTBW ( tcode ) and   create one datasource...
   so, you need to check that   related table also.. for that MBEWH table..
    ALL THE CLASSIFICATION RELATED DATASOURCES WE CAN'T CREATE DIRECTLY... JUST LIKE AUSP table also.. liek this..
regards

Error while creating datasource from view ZBSIS_VIEW

Hi all,
I could not create the datasource on the database table BSIS as it said "Invalid extract structure template BSIS of Datasource". I had suggestions that I should create a view and then create the Datasource on it. So I created the view and tried. But still I am facing an error message while creating datasource from custom Database View ZBSIS_VIEW.
"Invalid extract structure template ZBSIS_VIEW of DataSource"
Can anyone help on this regard.
thanks.

Hi,
Yes. You need a create a view on tables BSIS, BKPF and T001 as the currency/quantity fields in BSIS have reference fields from the other 2 tables.
In BSIS, in the currency/quantity fields tab, you have some ref tables and fields. You would need to include these tables and join in the view. You would also need to include the ref fields like WAERS, HWAE2, HWAE3, etc in the view. Then you would be able to create the datasource.

How to call a stand alone java application from ADF BC JSP, struts or JSF

Hi,
My requirement is that there are utilities or stand alone java applications that I want to call from our existing applications.
We have two seperate applications one ADF BC Struts application we developed using JDeveloper 10.1.2 and another ADF BC JSF application we developed using JDeveloper 10.1.3.2.
We want to integrate applications like JTwain and others to help us in scanning. The application will be placed on the same server as our application. How can I do this without loosing all the current session information.
Please help.
Thanks and regards,

There are two possible solutions.
First, if the tool or application you want to integrate, has an Java-API you can use this api and integrate the tool in your application (using one or more jars you add to the classpath).
Second, if the tool has no java api, you can call the tool via runtime.exec(...) as a shell process. This way you open a command shell in you application and execute the tool like you do on a normal command shell.
For tide integration and control I recommend the first approach. The second one is only for those tools which don't offer a java api.

Calling a web service through SSL via a stand alone java class

HI,
I am trying to call a web service through SSL via a simple stand alone java client.
I have imported the SSL certificate in my keystore by using the keytool -import command.
Basically I want to add a user to a group on the server. Say I add a user user 1 to group group 1 using an admin userid and password. All these values are set in an xml file which I send to the server while calling the server. I pass the web service URL, the soap action name and the xml to post as the command line arguments to the java client.
My xml file(Add.xml) that is posted looks like :
<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
xmlns:xsi = "http://www.w3.org/1999/XMLSchema-instance"

<groupName>group1</groupName>
<users>
<userName>user1</userName>
</users>
</namesp1:modifyGroupOperation>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
I call the client as:
java PostXML https://com.webservice.com/services/modifyGroup "/services/modifyGroup/modifyGroupOp" Add.xml
I my client, I have set the following:
System.setProperty("javax.net.ssl.keyStore", "C:\\Program Files\\Java\\jre1.5.0_12\\lib\\security\\cacerts");
System.setProperty("javax.net.ssl.keyStorePassword", "password");
System.setProperty("javax.net.ssl.trustStore", "C:\\Program Files\\Java\\jre1.5.0_12\\lib\\security\\cacerts");
System.setProperty("javax.net.ssl.trustStorePassword", "password");
But when I try to execute the java client, I get the following error:

Database connection pool to stand alone java class

Hi all,
I would like to know the best way to use a database connection pool with a stand alone java class.
In my web applications I usually use JDBC Data Source version 5 to connect to my database. In this case, I connect to an Oracle database. But in this scene, I've a WebSphere Application Server to provide this connection pool. But for stand alone applications, I don't know how to do because I don't have a Application server to run on.
Can enyone help me with this beginner question?
Best regards.

I tried to find the pool class I created but it must be on another CD. Anyway, you can easily create a number of connections and place them on a stack (your own or java's). When you need one, pop it off. When you are finished, push it back.
Good luck.

Diff was java add in and stand alone java instance

Hi Guys ,
What is the diff between was java add in and stand alone java instance ?
Thanks

Hai,
SCS is nothing but the SAP Central Services, it is AS Java instance of an SAP system containing the enqueue server and the message server.
JAVA Addin is inserted in exsisting ABAP only instance to have JAVA functionality. JAVA instance is assigned to an ABAP instance. The Internet Communication Manager (ICM) of the ABAP instance starts and stops the associated Java instance as required.
Netweaver JAVA (Stand alone) vs JAVA Addin:
Netweaver JAVA Addin installation is a dual installation that consists of Java and ABAP stack. Addin is required when you are implementing SAP XI (Exchange Infrastructure). Stand alone JAVA is required when you implement SAP EP (Enterprise Portal). It is generally not recommended to use dual installation for EP because this will expose the ABAP layer to the public Internet. So the ABAP stack is often used to host SAP ERP ECC (Enterprise Central Component), SAP CRM, SAP SCM, etc.,
Since the information hosted on ABAP stack is more sensitive in nature you are recommended to install Portal on the Netweaver AS Java server (Stand alone JAVA server).
By doing this you will be able to fully utilize the system resources for the portal and ensure good performance.
