Using a Java application as EJB consumer

Hi everybody,
I'm new to EJB, and I have to develop a desktop application that will interact with some EJBs. I've done so using JSPs/Servlets as the EJBs consumers, but I can't get it to work with my Java app.
I thought it would be as easy as including some JNDI code in my app, lookup the beans and invoke their methods, but all I get is an exception.
I've read in some tutorials, that the client needs to be registered in the server, or deployed at the same time (or I completely misunderstood it), but I'm still in a development stage, so I don't want to jar everything and redeploy...
I'm using Orion, and I get the following exception:
javax.naming.NamingException: META-INF/application-client.xml resource not found (see J2EE spec, application-client chapter for requirements and format of the file)
I've included though that META-INF/application-client.xml in my app jar.
I've been thinking about using web services as a more standard way to communicate, which do you think will be better?
Anyway, what am I doing wrong, or what should I do to make it work?
What other app server do you recomend?
thanks in advance!
Luis Javier

<--I've read in some tutorials, that the client needs to be registered in the server, or deployed at the same time (or I completely misunderstood it), but I'm still in a development stage, so I don't want to jar everything and redeploy...-->
No, client doesnt need to be registered in the server. If your client is a Java App you have to make sure that your app client classpath includes :
1) An Initial Context Factory class to create JNDI context, and it depends on server you deployed EJB components
2) An client support jar file, that contains Home,Remote interfaces and
their implementations of EJBs client will call. This support could be provided by your J2EE server deploy tool at deploying time. J2EE RI deploy tool, for axample, asks deployer if he wants to generate this jar file as he deploy an application containing some EJB module.

Can we call a webservice using standalone java application ?

Hi friends,
               Can we call configurd webservice in xi , using standalone java application by just giving url of webservice ?
              OR
              Only by means of WEBDynapro we can call ?
                Can you please tell me the answer for this .
Regards .,
V.Rangarajan

HI Ranga Rajan
well, If at all if you have webservice...you can import that werbserivce as External definition in to IR.
How to import:
1) Go to IR and and move to your requied component and there you can see the option called imported objects...select on imported objects where you can give the name and you can select the webservices which you want to use it.
2) Hope you are aware of that a werbservice will have the request and response.
3) Create the mapping program accroding to your requirement.
Go through blogs of Bhavesh and Naveen which talks about calling webservice in a specific condition:
Webservice Calls From a User Defined Function - /people/bhavesh.kantilal/blog/2006/11/20/webservice-calls-from-a-user-defined-function
Consuming/Calling webservices from DataBases - /people/sap.user72/blog/2005/10/20/consumingcalling-webservices-from-databases

Can we run the batch file using simple java application

Hello sir,
we want to run the batch file using simple java application. i tried with some example, we run the exe files but not batch file.
Runtime r = Runtime.getRuntime();
r.exec("D:\\jboss\\bin\\run.bat");
My application is server will run when we run the java appliation.
any suggestion? plz give me the solutions

yes you can run html file
WEB.SHOW_DOCUMENT is a built-in that is used in Forms to call URL from a Web Form. It works much like the similar way that a link on an HTML page works and it takes two arguments, one is URL and second one is TARGET, in your case use following.
WEB.SHOW_DOCUMENT('http://channas.iil.informatics.lk:8890/forms/frmservlet?config=abc.html', '_blank');
Hope this will work for you

Deployment failed. Building failed using sun java application server

Hi
am using netbean 6 ,glassfish v2 and sun java application server 9
When am try to run my jsp file am getting Deployment error report with further error given below.
Deployment error:
The Sun Java System Application Server could not start.
More information about the cause is in the Server log file.
Possible reasons include:
- IDE timeout: refresh the server node to see if it's running now.
- Port conflicts. (use netstat -a to detect possible port numbers already used by the operating system.)
- Incorrect server configuration (domain.xml to be corrected manually)
- Corrupted Deployed Applications preventing the server to start.(This can be seen in the server.log file. In this case, domain.xml needs to be modified).
- Invalid installation location.
See the server log for details.

BUILD FAILED (total time: 44 seconds)

Hi,
I've found that if you remove the j2ee-application element related to the enterprise app you are trying to deploy from Sun\AppServer\domains\domain1\config\domain.xml, and also remove your enterprise j2ee-app directory from Sun\AppServer\domains\domain1\applications\j2ee-apps\, it works.
This is not a permanent solution. I get the same error again, when I try to redeploy the application for the third time. Hope someone can help soon!
Thanks.

Use of java application w/ Swing component causes Win95 system to freeze

Hi All,
Until yesterday, we were having a major problem that whenever we ran a java applet or application that used Swing, the Windows 95 systems would freeze tight and require a reboot.
I had tried everything from loading the J2RE, Windows Sockets 2, J2SDK, none of which helped with the problem.
What we found out yesterday is the Windows 95 machines that were freezing didn't have DirectX on them, and that when DirectX 8.0a was installed, the freezing problem went away.
Just thought I'd share my success if anyone else is now struggling through the same items.

hii,
Well although the reply is litle bit late but i just wanted to thank you for your idea in installing direct x it worked fine also with a windows 2000 and 120 ram

Which application of Netweaver will be useful for JAVA professionals

Hi,
I am new to Netweaver and need to know which application of netweaver will be useful for me. I am basically a JAVA Programmer.
What exactly i can learrn in netweaver. EP,Webdynpro or XI.
Regards,
Sujan.

Hi,
Netweaver Portal(EP) is a frontend which provides one solid interface to all your applications, whether they are SAP or not. It runs on the java platform.
You can develop pure j2ee applications using the Netweaver Developer Studio, it has plug-ins which help in developing SAP technologies such as Web Dynpro, but you don't have to use it, you can develop your application using pure java technologies like EJB, jsp, etc. It also provides a solution for deploying your apps to the web application server.
In EP & WebDynPro, you can easily code if you have Java knowledge.Java is a big part of being a Portal Developer.
Hope this helps.
Regards,
Pooja.

Probably not, in pure Java. Depends on what the "hardware" is that you had in mind.

Hi Again Monty.
I may have given up too soon.
Click once on the downloaded TheGame.zip file to highlight it.
Press the Command⌘ + I keys, to Get Info.
Change Open With to Stuffit Expander.
Double-Click on TheGame.zip.
A folder titled TheGame will be created. Open that.
In there will be:
decks An Empty Folder
Game.jar
game.xml
images Folder This one has many sub entries.
preferences.properties
readme.txt
release_notes.txt
runme.bat
When I Get Info on Game.jar, Open With is set to Jar Launcher.
That's as far as I am going though. does that help any?

Java application won't start anymore

Hi,
I am using a Java Application (Protege) that was running just fine last week but today it just won’t start!
When click-on it jumps about 3 time in the dock and stop. I was able to run the connected .jar file but most of the features are not available this way.
I have not done anything special since last week beside Safari update (1.3.2.).
Any help is greatly appreciated.

Did you update Quicktime to 7.0.4? See if the following discussion seems relevant. There's a solution in the fourth message (reverting to Quicktime 7.0.1).
http://discussions.apple.com/thread.jspa?messageID=1500443
If that's the fix, the problem may be due to Protege using an outdated JavaApplicationLauncher. See

Sort order in Java application (oc4j container) -- ear file deployment

I have a Java application deploy in Oracle OC4J container (EAR file).
In my Java application (jsp), I have a SQL statement who return data but the
sort order is wrong. The letters "é" and all characters with accents
appears at the end of the result.
I tried many things to change the sort order (NLS parameters in database
and OAS10g parameter files).
When I use SQL*plus on database server, that's working.
The sort order is wrong when I use the java application.
Somebody can tell me what and where is the NLS parameters to change ?
Thanks
Robin

Robin,
I'm only guessing, but it could either be related to the java locale or the CHARSET attribute of the HTML header -- and nothing to do with the NLS parameters.
Maybe you should try the Globalization Support forum?
Good Luck,
Avi.
