Package my own beans in a jar

Hi,
I developped a few javabeans and i would like to package them into a jar to make these javabeans available to several applications.
myBeans.jar is located in C:\lib\ and contains :
com
---mycompany
-----businessBeans
--------xxx.class
-----technicalBeans
--------yyy.class
META-INF
---MANIFEST.MF
I added "C:\lib\myBeans.jar" to the classpath and in a java class I do:
import com.mycompany.technicalBeans.yyy;I get the following error message : the package com.mycompany.technicalBeans does not exist.
Please help :)

Usually IDE's and compile tools (ANT) override classpath settings when compiling java files.
You should add your jar to a library, if you use an IDE like JBuilder or add teh jar to a script file, if you use ANT.
If you just add it to system variable CLASSPATH that wont work.
best regards,

Do JNDI look up for entity beans from a session bean in different jars

I have a problem doing entity beans JNDI look up from a session bean which is deployed
as a separate package (session.jar) from the entity beans (entity.jar)
I believe if both session bean and entity beans are deployed into one jar and
I specify ejb-local-reference-description for session bean, it should work. However,
due to some reason, they have to be in separated packages but still in the same
container. Then question how to do JNDI lookup given entity beans only have local
interfaces?
FYI.
1 both session.jar and entity.jar are self-contained. i.e., no deployment error.
each JNDI name can be viewed from JNDI tree

Package javax.faces.bean does not exist

I am new to JSF. I tried to build a jsf application that runs on glassfish 3. I did not use IDEs.
When I compile it , I encountered the following 4 errors:
Error 1: package javax.inject.bean does not exist
Error 2: package javax.faces.bean does not exist
Error 3: cannot find symbol : class Named

Error 4: cannot find symbol: class SessionScoped

Please help me fix these errors.
Thank you in advance.

You must also be new to Java if you don't know how to deal with these problems. Do you even know what the classpath is?
I warn you right now: if you don't know the more advanced features of the Java platform (annotations, packages and the classpath, jar library usage, classloaders) you will basically get nowhere developing web applications - especially using a complex framework like JSF.

LOOKUP OF beans between two jar files

How to lookup beans between two jar file

if i want to lookup for 2nd jar (ejb2.jar)which has the same <ejb-name> how to do..

Hi,
No it would not be possible to differentiate the data just by using the dump files. You need to import these dump files in the database and then you can compare it for any difference.

You can modify the files in \templates\webapp or \templates\cabowebapp. I would recommend saving the original set prior to making any changes to the template files.

Packaging POF object class in a jar file

I have the following issue packaging a POF class.
I have two POF classes which are defined in the package oracle.communications.activation.asap.ace;
1. Token.java
2. Asdl.java
For simplicity i package them in the coherence.jar along with the other nessary artifacts.
"tokens-pof-config.xml"
<?xml version="1.0"?>
<pof-config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Then I startup the CacheServer it startsup fine. However when I invoke the POF classes from my weblogic artifacts I get the following error message.

======================================================================================================================
If I however define the classes in the default package or no package instead of package oracle.communications.activation.asap.ace;
Keeping everything else the same everything works fine.
====================================================================================
What do I need to do to make this work if I am packaging my POF classes not in the default package ?

Hi JK,
Well i have modified my POF classes since then and now created a package for them before I was just playing around and had them defined in a default package.
Second Baby steps here, once I get things working by packaging things in the coherence.jar file I will create my own jar artifact and add it to class path. As it is I have classpath issues. ...
So as I mentioned earlier.
I created the oracle/communications/activation/asap/ace directory added my two POF classes to it and then repackaged the jar.
It returns this error!

ORA-01722: invalid number when updating a CMP bean, SP10 WebLogic_RDBMS.jar problem?

Hi guys
We are having a problem with the migration to WLCS 3.2 SP2 / WLS 5.1 SP10.
We are moving from WLCS 3.2 and WLS SP6. Our CMP beans generate errors when
the container tries to update them. They deploy without error though.
See below for the stack trace
We use the recommended weblogic driver for our Oracle 8.1.7.0 database. WL
runs on w2k, and Oracle on Solaris 7.
Extract from set-environment:
SET DB_CLASSPATH=
SET PATH=%PATH%;%WEBLOGIC_HOME%\bin\oci815_8;%WLCS_ORACLE_HOME%\bin
SET
SQLPATH=C:\WebLogicCommerceServer3.2\db\oracle816;C:\WebLogicCommerceServer3
.2\db\oracle816\event;
Extract from weblogic.properties:
weblogic.jdbc.connectionPool.commercePool=\
url=jdbc:weblogic:oracle,\
driver=weblogic.jdbc.oci.Driver,\
I made a few experiments, and I noticed that generating the CMP classes
(with EJBC) with the old WebLogic_RDBMS.jar (from WLS SP6) is working fine.
Here is what I mean : ejbc uses the library
c:\weblogic\lib\persistence\WebLogic_RDBMS.jar And this library has changed
with SP10. However since that change and after rebuilding our jars, all CMP
entity beans fail to update.
If I just replace that WebLogic_RDBMS.jar with the previous one (from SP6),
and without changing anything else, our CMP beans work fine. I did not
change any driver or xml deployment descriptor.
One of the generated files in the jar (for our bean
VisibilityPSWebLogic_CMP_RDBMS.class) differs, and that seems to be the
cause of the problem.
I jadded that class and here is a difference I notice:
OLD, ejbc ran with SP6 WebLogic_RDBMS.jar : visibilitybean.targetCompanyId =
(BigDecimal)resultset.getObject(5);
NEW, ejbc ran with SP10 WebLogic_RDBMS.jar : visibilitybean.targetCompanyId
= resultset.getBigDecimal(5, 35);
Similar differences for the SETbigdecimal.
Dunno if that will help, but I'm attaching the 2 jar files with explicit
names.
Damn that was long, I hope someone will read it... Thanks for any help on
this, see stack trace attached below

You are using WebLogic jDriver for Oracle which needs exact version of OCI API, that comes with the Oracle client installation. Ensure that you have installed the right Oracle client version. And updated the PATH properly.
I notice that you have
bin/oci815_8
oracle816
Thsi looks liek the inconsistency in your environment.
What you need to do is
1. find oci817_8 and place that in the PATH.
2. install oracle 817 and use that client and set the ORACLE_HOME environment variable and the PATH properly.
Try this and see if it helps.
BTW - WLS 5.1 is EOL

Can I deploy the entity bean in different jar files?

I have an application EAR, which contains several JARs. I have an entity bean A that has relationships with 2 other different entity beans B and C in the same DB. Now, I have to deploy this entity A together with B in AB.jar, and A with C in AC.jar. Both AB.jar and AC.jar are modules of the same application EAR file. They all use the same data sources to the same database, and named by different <ejb-name>.
I have no problem with deploying the app to WebLogic 8.1. But the JSP page accessing entity A got errors. Sometime, it got error complaining that the container-generated ejbFindAccount mehtod is abstract.
My questions are,
Can an entity bean be defined twice in 2 different jars?
When container load AB.jar and AC.jar, does it generate the finder methods twice?
I guess there are some name conflicts going on here. What should I do to avoid it?
Any comments are very much appreciated.

Thanks for your answer, but how can I use it in connection with relationships?

Do I have to write a new <entity> where I define the referenced entity?

WebLogic 12.1.2 fails when injecting extension in jar into bean in same jar

WebLogic 12.1.2 fails when deploying a web application that contains a jar in which an extension is injected into a bean that resides within that same jar. The following exception is thrown:
"weblogic.management.DeploymentException: org.jboss.weld.exceptions.DeploymentException: WELD-001408 Unsatisfied dependencies for type [SampleExtension] with qualifiers [@Default] at injection point [[field] @Inject private test.ApplicationBean.extension]"

The problem can be easily reproduced by a minimal case with the following structure:
war-root
     WEB-INF
         beans.xml
         lib
            somejar.jar
And with somejar.jar having the following structure:
test
    ApplicationBean.java
    SampleExtension.java
META-INF
    services
        javax.enterprise.inject.spi.Extension
    beans.xml
ApplicationBean can looks as follows:
@Named
@ApplicationScoped
public class ApplicationBean {
    @Inject
    private SampleExtension extension;
    @Inject
    private BeanManager manager;
    public void myMethod() {
        System.out.println("Extension:" + extension + " Manager:" + manager);
And SampleExtension can be:
public class SampleExtension implements Extension {
    public void onBeanDiscovery(@Observes AfterBeanDiscovery beanDiscovery, BeanManager beanManager) {
        out.println("Extension called");
I published a minimal web application (as Maven multi-module project) that reproduces the case here: https://github.com/arjantijms/inject-extension
This application runs fine on basically every other Java EE server (tried specifically JBoss EAP 6.1, GlassFish 4.0 and TomEE 1.5.2), but not on WebLogic 12.1.2.
Note that I'm not really a WebLogic user. I'm an open source library writer who's trying to make our library (OmniFaces) to run on all Java EE implementations. This case is part of a functionality in our upcoming release.

Hi,
If it is war then try to apply following Patch 13893259.

Packaging and accessing resources in a JAR

I'm working on an application and I would like to package my resources (icons, about dialog images, splash screen images, release version text, etc.) in the jar file I'm going to distribute for deployment. I would like to access these resources from the JAR file in my deployed code. But I would also like them accessible when I'm running the code in my Eclipse IDE. Is there a way to do this using only one code base?
My Eclipse project structure is src (folder) which contains my source code, bin (folder) which contains my class files and res (folder) which contains my resource files.
I am using the javapackager utility to create my deployment JAR and build a self-contained deployment .exe for deploying to Windows.
Is there a way to have the javapackager build a single JAR file from multiple sources (i.e. my bin and res folders)? What do I have to do in my code so that the same code can be used to load resources when I'm running in Eclipse and the self-contained deployment?
Thanks,
Mike

The Java Tutorials has several trails for loading resources.
Retrieving Resources (The Java™ Tutorials > Deployment > Java Web Start)
Use the getResource method to read resources from a JAR file. For example, the following code retrieves images from a JAR file.
// Get current classloader
ClassLoader cl = this.getClass().getClassLoader();
// Create icons
Icon saveIcon = new ImageIcon(cl.getResource("images/save.gif"));
Icon cutIcon = new ImageIcon(cl.getResource("images/cut.gif"));
The example assumes that the following entries exist in the application's JAR file:
•images/save.gif
•images/cut.gif
See that last sentence?
You put what you need in the jar file and then use the 'getResource' methods to load them.

Trying to use ProgressBar demo to build own bean

Hello, I have a working form and I'm experimenting with PJCs. I'm using the progress bar demo as the starting point. My form only shows a grey box; communication with the bean does not seem to work.
I have added a bean area to my form. I have created jar file with two classes: an LWComponent and a VBean. I have formsweb.cfg ARCHIVE referencing this jar (along with frmall.jar). I have the jar file in the CLASSPATH in the default.env file. The jar exists in the directory referenced in class path (and has permissions to it). I have signed the jar using a modified sign_webutil.sh (it appears to succeed). I have restarted OC4J.
I have a when-button-pressed trigger set to do this:
BEGIN
SET_CUSTOM_PROPERTY('IMAGEVIEWERPJC', 1, 'CLEARALL', 1);
SET_CUSTOM_PROPERTY('IMAGEVIEWERPJC', 1, 'APPR_ID', :appraisal.app_id);
SET_CUSTOM_PROPERTY('IMAGEVIEWERPJC', 1, 'CONNSTR', GET_APPLICATION_PROPERTY(CONNECT_STRING));
SET_CUSTOM_PROPERTY('IMAGEVIEWERPJC', 1, 'POPIMAGES', 1);
Message('Should have: ' || :appraisal.app_id || ' Got: ' || GET_CUSTOM_PROPERTY('IMAGEVIEWERPJC', 1, 'APPR_ID'));
SET_CUSTOM_ITEM_PROPERTY('IMAGEVIEWERPJC', 'CLEARALL', 1);
SET_CUSTOM_ITEM_PROPERTY('IMAGEVIEWERPJC', 'APPR_ID', :appraisal.app_id);
SET_CUSTOM_ITEM_PROPERTY('IMAGEVIEWERPJC', 'CONNSTR', GET_APPLICATION_PROPERTY(CONNECT_STRING));
SET_CUSTOM_ITEM_PROPERTY('IMAGEVIEWERPJC', 'POPIMAGES', 1);
Message('Should have: ' || :appraisal.app_id || ' Got: ' || GET_CUSTOM_PROPERTY('IMAGEVIEWERPJC', 1, 'APPR_ID'));
END;
The bean should should see the POPIMAGES property being set and then use the other information to access a database and display images. But the bean area is always grey.
The messages show that :appraisal.app_id is "46" (which is correct) and "Got: " is blank(null). So the beans APPR_ID property is not being set.
I don't seem to be able to communicate with the bean... IF it's even running.
I'm hoping there is an obvious step that I'm missing. 8-)
Thank you for any help.

New development: I modified formsweb.cfg. This time the webutilarchive variable. It now looks like this:
WebUtilArchive=frmwebutil.jar, jacob.jar, ImageViewerProfile.jar
After restarting OC4J and hitting the URL, a window popped up and said "downloading libraries"; three progress bars, one after the other, zipped by. Then the pop-up went away.
Woohoo!
The java bean area is still grey. And my button still doesn't change anything. And the debug messages I output still show that forms is not able to get/set any of the beans properties.
But I got a pop-up!! 8-)

Want to package a class file and a jar file in main jar file

hello folks,
i have a class named launch.class
and a jar file named First_Sample2.jar
First_Sample2 is an application that i have made which requires more memory than is generally allocated by the JRE. so, launch.java file just contains code to execute the command:
javaw -Xms128M -Xmx256M -jar " + path + "First_Sample2.jar"
where path variable refers to a directory which contains First_Sample2.jar
problem is that the only way i can use this code is by keeping two separate JAR files, one is launch.jar, the other is First_Sample2.jar and then execute launch.jar, which will in turn call First_Sample2.jar (which means I have to provide anyone with 2 separate files if they want to use my application)
is there any way in which i can combine both these jar files into one?

Well there is a couple ways you can achieve this, but I am telling you that packaging a JAR within a JAR will not work because classes within the internal JAR will not be recognized on the classpath.
The easiest way to get the user to run your program with a simple double click would be to hide the two JAR files from them completely, having them reside in a folder somewhere on the user's computer. I would use a batch file (Windows environment) or an .sh file (Unix) that would set up your classpath variable and then call java to execute the main class in your main JAR.
For instance:
cd [Where java.exe resides]
set CLASSPATH=[semi-colon delimited absolute file paths pointing to your two JAR files and any other JAR files that they reference]
java -cp %CLASSPATH% [main class]
The user would have access to this batch file, perhaps on their desktop, where they can double click to execute teh program just as if it were an EXE file. This is the best way because it hides the JAR files from the user.
If you would like to combine the two JAR files however, you would need to extract the contents of the secondary JAR file and then include them in with the contents of the main JAR file. That is the only other way that all classes are visible on the classpath.

Builtin package VS own package

I have created one own AWT package.In my own AWT package cotains methods are same as in built-in AWT package. I am importing built-in awt package also. I am accessing one method .. which package will execute ??? will it execute my own package or buitl-in package??
Pl. answer the above question.
Regards & thanks,
srinivas

I assume you are talking about classes rather than methods. There's no problem with methods with the same name etc. if they are in different classes.
It's not a good idea to have more than one version of the same class (including package name) available but, if you do, which one you get depends on the order of items in your classpath.
You should not be creating your own classes with package names starting with java anyway. If you want to create your own awt use your own package name, then there's no ambiguity.

How to get the owning bean given a java object

Hi, is there any way - for a just-created bean instance - to know on behalf of which bean this object has been created ?
In other words, going back from the java object to the bean symbolic name, as described in a faces-config managed-bean chunk (just the opposite of resolveVariable) ?

You want to get the definied managed bean name inside the backing bean?
If so, call this inside the backing bean: private String getManagedBeanName() {
    String managedBeanName = null;
    HttpServletRequest request =
        (HttpServletRequest) FacesContext
            .getCurrentInstance()
                .getExternalContext()
                    .getRequest();
    // Lookup bean in request scope.
    Enumeration requestAttributeNames = request.getAttributeNames();
    while (requestAttributeNames.hasMoreElements()) {
        String requestAttribute = (String) requestAttributeNames.nextElement();
        Object object = request.getAttribute(requestAttribute);
        if (this.equals(object)) {
            managedBeanName = requestAttribute;
            break;
    if (managedBeanName == null) {
        // Bean is not in the request scope. Lookup it in session scope.
        Enumeration sessionAttributeNames = request.getSession().getAttributeNames();
        while (sessionAttributeNames.hasMoreElements()) {
            String sessionAttribute = (String) sessionAttributeNames.nextElement();
            Object object = request.getSession().getAttribute(sessionAttribute);
            if (this.equals(object)) {
                managedBeanName = sessionAttribute;
                break;
    return managedBeanName;
}
