Stand Alone java client for calendar server

I am using washington calendar client as a desktop client for calendar server.Can anyone help me on how to use it with JES?.
I have the following questions on it.
1. Whats the way to edit the calendar client? Eg suppose we want to fix an appointment.,how it can be done on that calendar screen?
2. How can we share a calendar among different users?
3.What is the database being used to store the details about the tasks entered on calendar client?.
4.What are the security features available?.

"Pierre-Yves Fourmond" <[email protected]> wrote in message news:<3bf38eb0$[email protected]>...
I have an EJB deployed on WebLogic 6.1 on my NT machine and I try to reach it
with a Java client program on that same machine.
Properties prop = new Properties();
prop.setProperty (Context.INITIAL_CONTEXT_FACTORY,
"com.sun.enterprise.naming.SerialInitContextFactory");Hi Pierre,
For a start, you need to use the
"weblogic.jndi.WLInitialContextFactory" as the naming factory.
Hope this helps

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).

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.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

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 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"
xmlns:SOAP-ENC = "http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENV = "http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd = "http://www.w3.org/1999/XMLSchema"
SOAP-ENV:encodingStyle = "http://schemas.xmlsoap.org/soap/encoding/">
<SOAP-ENV:Body>
<namesp1:modifyGroupOperation xmlns:namesp1 = "/services/modifyGroup/modifyGroupOp">
<auth>
<user>adminUser</user>
<password>adminPassword</password>
</auth>
<operationType>ADD</operationType>
<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:

NameNotFoundException in JNDI lookup in for stand alone App client in EJB3

I created an ejb module in netbeans 5.5 added a session facade (SavingsaccountFacade) and downloaded it to SunAppServer 9 (java EE 5). When I try and access the JNDI name in a stand alone java application client using the following code
Context initial = new InitialContext();
Object objref = initial.lookup("ejb/SavingsaccountFacade");
I get the following errors:
javax.naming.NameNotFoundException: SavingsaccountFacade not found
at com.sun.enterprise.naming.TransientContext.doLookup(TransientContext.java:203)
I have added j2ee.jar, appserv-rt.jar, and the dist/SavingsAccount.jar to the library. When I do a similar thing in J2EE1.4 it worked fine.
Can somebody help please.
Thanks

Hi Dave,
Here's our EJB FAQ entry that explains how EJB Global JNDI names are set in the
Java EE 5 SDK and Glassfish. The most likely explanation is that the name used
in the client does not match the one assigned to your EJB in sun-ejb-jar.xml.

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.

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;

          try

               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);

               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 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.

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.

Java beans for calendar utility

Hii Javaities
I need to have calendar in my jsp for choosing dates
Earlier i was uisng javascript for calendar but now i want to use Java beans .
Can i use Java beans for calendar ?
Are there any tag libraries for tht ?

PDAs ? hmm...sounds interesting
what technology have u thought of using for your application ?
java microedition ...[certainly not c++ or .net] ?
Is it going to be a stand alone application on a PDA .
OR
Are you thinking of wireless internet connectivity to the PDA? In this case your application might have to be designed strickly so that it fits the screen size.
How about a tablet PC? It good for mobile computing and is handy too.

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
Sonam

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.

Yoganand.V

In my Web Service, I have one GetSum java class, which has a method addSum(int x, int y) and this method returns the sum of x and y. I am able to successfully test the addSum method in the web service via the end point. However, I would want to use the addSum() method of the web service in a stand alone java class. For this I have used the wsimport utility and the WSDL of the webservice, from which I have got the following java classes.
AddSum.class
AddSumResponse.class
GetSumWS.class
GetSumWS_Service.class
ObjectFactory.class
package-info.class
I have packed all the above class into a jar file.
I have tried many options provided in various websites, but am not able to get this resolved. I am pasting the WSDL for any reference

Can someone please provide me the code to invoke the addSum() method in a stand alone java class. I would really appreciate the help
Thanks,
Suresh

Hi,
The following is my code to invoke the addSum() web service method.
package com.FirstWS;
import com.firstws.*;
import com.firstws.GetSumWS_Service;
import com.firstws.GetSumWS;
import java.rmi.RemoteException;
public class useWS {
public static void main (String[] args) {
GetSumWS port = null;
try {
int number1 = 10;
int number2 = 20;
port = new GetSumWS_Service().getGetSumWSSoapHttpPort();
System.out.println ("Invoking addNumbers(%d, %d)\n"+ number1 + number2);
int result;
result = port.addSum(number1,number2);
System.out.printf (
"The result of adding %d and %d is %d.\n\n",
number1, number2, result);
} catch (Exception ex) {
System.out.println ("Caught Exception: %s\n"+ex);
But when I compile, I get the following error: "Error(14,20): Service not found in class com.firstws.GetSumWS_Service in class com.FirstWS.useWS"
Please let me know where I have wrong, and would appreciate if you could correct it.
Thanks,
Suresh

Socket Communication between java client and c++ server

HI,
In my project,I want to do the following:
1.Sending datas from client to server.
2.Getting the response from server to client.
I written the client in java.but the server is in c++.
Is it possible to communicate with the server using java codings itself?
Im able to send the data from my java client to the server.
but unable to get back the datas from server to client.
Can anyone tell me how to do this?
thanks a lot

hi
thanks for ur reply.
I didnt get any error msg while getting the back the datas.
Actually i divided my application into two parts.
My application will act as both server and client.
server ll get the browser request and send to the client and the client will send that data to the c++ server.
Im able to do that.and unable to get the data from server.
Didnt get any error.
can u tell me how to make an application to act as both client and server.
I think im wrong in that part.
thanks a lot
