Question about ear file and jar file

I have an ear file that I built using ant. Say my project name is test. So my ear file name is test.ear. Everytime I try to deploy the ear file, weblogic complains about not finding the test-ejb.jar. I'm confused as to why weblogic expects a test-ejb.jar in the ear because I didn't intend to put one in. My question is whats inside the ear file that weblogic thinks it needs the test-ejb.jar? I went through the file, but couldn't find anything that should tell weblogic that it should find a test-ejb.jar. In addition, I don't have either weblogic-ejb-jar.xml or ejb-jar.xml in the ear file. Any help would be appreciated.
Thanks in advance.

An EAR should have an "application.xml" in the META-INF directory within the JAR. You might take a look at it. I suspect there is an EJB module specified by that name.

Are JDev autogenerated paths needed to create ear, war and jar files ?

Hi
We want to create ear, war and jar files from Ant build script generated from JDeveloper 11.1.1.7.
We also like to use ojdeploy with it.
In the process of creating build.xml files from projects, we see these paths.
We also have standalone Weblogic installed with ADF runtime 11.1.1.7
Questions:
1- Do we need these path ids to generate ear, jar, war files properly and then deploy the ear to our standalone Weblogic so that our webapp can run ok ?
2- Why are they generated, if they are not needed
From research, it appears that we don't need these paths except to keep ant targets of init, compile, exec etc with ojdeploy.
3- Is that true ?
We are afraid that because no paths are listed in the build.xml, then when we deploy the ear app, it cant use the ADF runtime on the standalone WLS.
Thanks in advance for answering.
Sincerely
eg of paths generated below:
<path id="library.SOA.Designtime"/>
<path id="library.SOA.Runtime"/>
<path id="library.BPEL.Runtime"/>

There are two different things here. Using ant to build the class files and then building an ear from the class files and other resources.
The building part needs the libraries if you use javac as compiler. Building an ear file only needs the path to the jar files which are packed into the ear.
In this sense you need the pages you see in the build.xml.
Then Jdev offers another way: ojdeploy. This tool is a Jdev without a gui.
You can use this tool and build the classes for each project of a workspace and to build build war and ear file. This is just like you click the rebuild button for each project and then the deploy the projects and application. If you use this approach you don't need the generated path ids as the whole build process is done inside Jdev as it's done on your developer pc.

How to run .class file and .jar file in jdev9i

I want to run .class file and .jar file in jdev9i,what should I do?
Also,I want to generate .class file and .jar file in jdev9i,what should i do?

Add the .class file containing the public static void main(...) method to the project by clicking on the + toolbar button in the navigator, open the project properties and properly set the additional classpath then right click on the .class in the navigator and say run. It should work, I've just tried it.
Doesn't work for a .jar yet, in JDeveloper 9.0.3 it works both for .class and .jar

Question about using third party jar files in Java Web Start Environment

Hi everybody, I got a very strange problem and still can't figer out how to solve it. Can anyone help to overcome this problem?? Thanks in advance.
Question: I wrote a simple java swing application to connect to Oracle database. I packed whole my classes and a third party jar file(classes12.jar) to a new jar file named "IRMASSvrMgntGUI.jar" and then use command 'jarsigner' to signed IRMASSvrMgntGUI.jar. There is no problem when I execute 'java -jar IRMASSvrMgntGUI.jar' in the command line. But when I execute this application via Web Start Environment, an "java.lang.NoClassDefFoundError: oracle/jdbc/driver/OracleDriver

contents of the manifest file I used to create this jar file are as follows
===================================
Manifest-Version: 1.0
Main-Class: IRMASSvrMgntGUI
Class-Path: classes12.jar
Created-By: 0.9a (itoh)
===================================
and file structures in "IRMASSvrMgntGUI.jar" is
====================================
META-INF/
classes12.jar
DBAuthenticateDialog.class
DBConnection.class
IRMASSvrMgntGUI.class
====================================

If you directly include classes12.jar in IRMASSvrMgntGUI.jar, the classloader won't be able to find the classes inside classes12.jar. You should sign classes12.jar separately and include that in jnlp along with your application specific jar. When you're launching your app using "java -jar somefile.jar" then the classpath settings in manifest file are used, but that's not the case when you start using JWS since in this case the classpath is based only on the " <jar href=..." entries in jnlp.

How to create dll file and jar files in oracle forms ? and how to use in oracle forms?

pls teach me....

Your question is more related to batch programming.
From what I understand, you want to add 100 [ :o ] jars to the classpath to execution and you probably don't want to write all the names in the batch file. There's a simple way of adding jars by running a loop. The code should look like the following:
dir /b "%LIBDIR%\*.jar" > temp.tmp
FOR /F %%I IN (temp.tmp) DO SET CLASSPATH=%CLASSPATH%;"%LIB_DIR%\%%I"
del temp.tmp

Classpath and jar file question

my application need to use few jar files i downloaded from the internet
so i need to set the classpath so that i can import the packages in the jar file rite?
let say set classpath=.;c:\somedir\bin;
the ".;" after the "=" means that i search the current directory first then search the directory i have specified after that rite?
if so, can i put all the needed jar files in the current directory so that my application can use them??
Another question is if all the jar files in located in the same directory how can i set the class path to refer to them without sepecifying each of the jar file name??can i just put the directory path and will it locate them automatically when my application start??
can anyone tell me about it??thanks

No, you need to include each and every jar file in your classpath.
Or put them all in your <jdk_installation_dir>\jre\lib\ext directory, so that they will get included in your classpath automatically.

How to Add JAR files and Config files to CLASSPATH at runtime?

QUERY:
During runtime, I need to load the JAR files and relevant config files( .cfg files and .properties file) into CLASSPATH and run a specific java program from one of the JAR which is available in CLASSPATH.
Please advise me any relevant Java API details or a sample java program to implement the above use case.
Thanks in advance.

You don't add to YOUR classpath once your app is launched.
You create a NEW process for the app you want to run and provide the proper environment for it to run in - including any PATH or CLASSPATH environment variables.
The Java API for the ProcessBuilder class has a simple example that shows how to create the arguments and launch an external application.
ProcessBuilder (Java Platform SE 7 )
There are also PLENTY of other examples of using ProcessBuilder; just search the net.

Protecting jnlp and jar files

Hi
I would like to know how to protect the jnlp and jar files against anyone who just types the URL in the browser Address bar.
Thanks
Steven

Haven't tried, but if your jnlp app must check for updates on every startup and your files (both jnlp file and jars) are in a password protected folder (using digest or plain authentication over a SSL connection, for example) then you may be in trouble. Will JWS recognize this situation on an update check and prompt for login/password? (related to web server's folders).
