Question

Get a jar for my heavy container connecting to EJB in Netbeans

Asked by: Nargzul

Hi!

I've done a small program that connect to my EJB server, It works on debugging under Netbeans but now I want to test it on a serveur that hasn't netbeans.

I've viewed that netbeans generate two jar for this container. I've deployed the one that doesn't have a -client.

After this I've try to launch the program but it appears it don't know which class he must start. But in the netbeans properties it's specified.

So my question is simple:
What is the good way to create a .jar(or the two jars) that will connect to my EJB server.

Thank you!

I am not to sure if you need to deploy the second jar at all. When you deploy the jar containing the the beans all you need is a stand alone client to do the lookup of that bean and that functions independently. So I am not sure why you need the second jar.

 

by: NargzulPosted on 2009-07-18 at 04:28:15ID: 24885623

Okay, so how I generate this stand alone client?

 

by: a_bPosted on 2009-07-18 at 10:59:47ID: 24886743

No need to generate it. You can write a java bean/pojo as a client and use that. Do the lookup and access the ejb.

 

by: NargzulPosted on 2009-07-20 at 05:19:48ID: 24894307

So how I run it?? I've tried to make a javac, etc, but I've missing library(javax.ejb by exemple).

 

by: a_bPosted on 2009-07-20 at 05:22:03ID: 24894321

You can run it through the javac but make sure you include the right libs in the class path by using the javac flags.

 

by: NargzulPosted on 2009-07-20 at 05:24:21ID: 24894341

I've watched in my Netbeans project, the only imported lib is my EJB project.

If we do a javac, are you sure it use J2EE and not J2SE? Because I think this missing lib is in the J2EE and not J2SE.

 

by: a_bPosted on 2009-07-20 at 05:37:15ID: 24894442

Yes I am sure..........the netbeans lib link the required libs internally and generate the classpath.

 

by: NargzulPosted on 2009-07-20 at 05:39:24ID: 24894457

Okay, so what is this library? Where can I found it?

Glassfish V2U2

 

by: a_bPosted on 2009-07-21 at 05:08:46ID: 24903539

Check in  the lib directory, it should be there.

 

by: NargzulPosted on 2009-07-21 at 05:13:06ID: 24903587

which lib directory? Of glassfish? Of the project? What is its name?

The only lib directory I've found in this client container application is the jar of my EJB project

 

by: a_bPosted on 2009-07-21 at 22:24:35ID: 24911743

Open the directory where glassfish is installed, there should be a lib directory inside the server dir. Place the entire directory in the classpath.

 

by: NargzulPosted on 2009-07-22 at 06:42:18ID: 24914717

Okay, the lib folder has something like 75Mo of libraries.

I've try this:


"C:\Program Files\Java\jdk1.6.0_14\bin\javac" -classpath "C:\Program Files\glassfish-v2ur2\lib;C:\Users\J4N\Desktop\TrustBN-ejb.jar" MatchBot.java

But I always got same error:


C:\Users\J4N\Documents\My Dropbox\WorkSpaces\J2EE\TrustBN\TrustBN-app-client\src\java\MatchBot>"C:\Program Files\Java\jdk1.6.0_14\bin\javac" -classpath "C:\Program Files\glassfish-v2ur2\lib;C:\Users\J4N\Desktop

search for some ejb specific lib inside the folder.........can you list those out. Do a searcg *ejb*.jar in the lib folder and post the results.

 

by: NargzulPosted on 2009-07-22 at 10:56:30ID: 24917753

I've some DTD and XSD about ejb, but no jar with the ejb in the name.

Any progress  on the issue as yet?

What is the pacakge name that you have specified and how to do you invoke in from the command line? You need to be at the right package level.

 

by: NargzulPosted on 2009-07-28 at 04:54:11ID: 24959724

No :(

I've show how I call it.

The package is MatchBot.
