Unable to use Class Designer when deriving Entity Bean from another class

I have several Entity Beans that have common fields. In order to maximise reusability, I have defined a base class which contains these common fields and corresponding get/set methods on these fields.
In the next step, I build an Entity Bean using JDeveloper. I then go to Source Editor and in the Bean class, modify the Java code to inherit from this base class that I have defined. I then try to go to Class Designer expecting to see the inherited fields as well.
However, this is the error I get :
"Error while trying to parse source file...."
Any pointers on resolving this would be a great help ! Thanks !!!

If you're running >Java 1.4, you'll need to put your classes into a package since Tomcat can no longer import the class 'BeanProdess' which is in an unnamed namespace.
Your JSP is compiled into a class (in the package org.apache.jsp) that doesn't recognize anything in the default package.
Here's a reference if you want to read about this.

Entity bean with another class as primary key generator class

Hi All,
I have a CMP entity bean in which I generate the primary key using my own class know as unique id generator.
I use it in ejbCreate method in the following manner
public Long ejbCreate(HospitalData hospitalData) throws CreateException{
          Long myid = new Long(UniqueIdGenerator.getId());
          System.out.println("My id generated ====== "+myid);
          this.hospitalid = myid;
          System.out.println("My id generated ====== "+this.hospitalid);
          System.out.println("Came in ejbCreate method of HospitalEJB");
          this.hospitalname = hospitalData.getHospitalname();
          return null;
Can you tell me how I map this primary key in my ejb-jar.xml and jbosscmp-jdbc.xml.
Anyhelp would be appreciated.
Thanks

I am trying to develop an entity bean attached to a key which have a
composite key using Primary Key Class. When I use the findByPrimaryKey
method of the bean it throws an exception as follows,I notice that you are using the reference CMP plugin.
at com.netscape.server.ejb.SQLPersistenceManager.find(Unknown Source)I'm also willing to bet that you may have created your own primary key class
with a single field, rather than using the fields type as a primitive
primary key class. If you do this, then SQLPersistenceManager will break.
It is badly written, and has some stupid assumptions. The one I remember
the most is that if you only have one primary key field, then
SQLPersistenceManager assumes you have used a primitive type such as
java.lang.String or java.lang.Integer, to represent it, rather than creating
your own <Enity>Pk.java file.
SQLPersistenceManager works for toy examples, but in general I would say it
is broken and unusable. Either use BMP, or splash out the money for Coco
Base from Thought Inc. Currently the only CMP plugin for iPlanet App server,
other than the reference implementation, that I know of.

Can't add list element when calling a method from another class

I am trying to call a method in another class, which contains code listmodel.addElement("text"); to add an element into a list component made in that class.
I've put in System.out.println("passed"); in the method just to make sure if the method was being called properly and it displays normally.
I can change variables in the other class by calling the method with no problem. The only thing I can't do is get listmodel.addElement("text"); to add a new element in the list component by doing it this way.
I've called that method within it's class and it added the element with no problem. Does Java have limitations about what kind of code it can run from other classes? And if that's the case I'd really like to know just why.

There were no errors, just the element doesnt get added to the list by doing it this way
class showpanel extends JPanel implements ActionListener, MouseMotionListener {
       framepanel fp = new framepanel();
       --omitted--
     public void actionPerformed(ActionEvent e){
              if(e.getSource() == button1){
                   fp.addLayer();
/*is in a different class file*/
class framepanel extends JPanel implements ActionListener{
        --omitted--
     public void addLayer(){
          listmodel.addElement("Layer"+numLayer);
          numLayer++;
}

Calling Local Entity Beans from another Application

Hi,
I packaged all my Local entity Beans in 1 single Application (APP1.EAR).
I then I have another Application (APP2.EAR) which is made of Session Beans which require access to the APP1 application.
I'm using this code to achieve this:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "admin");
env.put(Context.SECURITY_CREDENTIALS, "manager");
env.put(Context.PROVIDER_URL, "ormi://<host>/APP1");
context = new InitialContext(env);
... (BeanLocalHome)context.lookup("java:comp/env/ejb/BeanLocal");
I get the Following Exception:
javax.naming.NameNotFoundException: java:comp/env/ejb/BeanLocal not found
1) is there any problem with this code?
2) can local interfaces be accessed by another Application (or can they be accessed only by the same application) ?
Regards.

Hi ,
thank you for your answer.
I'm still in trouble:
these are the steps:
App1.jar entity beans.
App2.jar Session bean.
I embedded the App1.jar into the App2.ear
dir :
App1.jar
App2.jar
application.xml (added the App1.jar)
then I added this in the ejb-jar.xml deployment descriptor for App2.jar
<ejb-link>../App1.jar#BeanName</ejb-link>
for each entity bean.
But I still get :
javax.naming.NameNotFoundException: java:comp/env/ejb/BeanNameLocal not found
java.lang.Object com.evermind.server.ApplicationContext.lookup(java.lang.String, boolean)
ApplicationContext.java:110
java.lang.Object com.evermind.server.ApplicationContext.lookup(java.lang.String)
ApplicationContext.java:66
java.lang.Object javax.naming.InitialContext.lookup(java.lang.String)
What am I missing ??
Thanks.

Recommended way of getting entity manager from pojo class

Hi,
In our application we have the need or retrieving entity manager from 'pojo' classes.
More specifically we have singleton classes which act as 'data' repositories and are accessed from both servlets and ejb.
I'm aware that the repositories classes might be problematic, but in the current stage we can't perform significant change in application structure so I am looking for a 'fast' solution as possible.
The best way will be to lookup entityt manager in JNDI, but as I undestand this feature is not avaialabe in weblogic.
I understand that the preffered way for getting entity manager in such situation is by using @PersistenceUnit annotion on the calling location and lookup entityManager by that name in the pojo. This is however problematic for us since since we access the repositories from variouse locations (many different classes).
Possible additional solutions we thought of:
- creating an 'entity manager factory' locator ejb. This is an ejb with no transaction attribute, which has one method getEntityManagerFactory. It injects entityManagerFactory and returns it. This is the fastest soltion to implement. Is this a valid one?
- using application managed entity manager in such situations. We have a problem doing so now because the creation seems to fail for variouse reasons.
What is the recommended way?
Thanks.

To obtain an EntityManager instance, first must obtain an EntityManagerFactory instance by injecting it into the application component by means of the javax.persistence.PersistenceUnit annotation:
@PersistenceUnit
EntityManagerFactory emf;
Then, obtain an EntityManager from the EntityManagerFactory instance:
EntityManager em = emf.createEntityManager();

Use a method from another class in another package?

How can I use a method from another class in another package?

WhiteJ wrote:
What do you mean by "new keyword?" You posted this previously:
I tried that, it seems to not be working. I want to use the constructor from the other class. I imported it, using this piece of code:
import components.FileChooser;
components.FileChoser();
Typically if I am going to call a constructor on a class called Fubar, I'd use new to create a new object:
Fubar myFubar = new Fubar();Incidently, is it a simple typo in your post or are you trying to use a FileChoser object when it should be FileChooser?

Using a class that has a main from another class

Can I call a class that has a main from another classes public methods?

Yes, you can, although strictly speaking you won't be calling that classes "main" method, you will simply be calling and initializing the class through it's constructor, the "main" method will be ignored. If you have code inside your main method that you want executed as well consider moving it inside your constructor and simply using the "main" method as an application initializer:
public static void main( String args[] ) {
new MyClass();
This way you can use your class as an application or call it from another class and not have any duplicate code inside your "main" method and constructor. You can also take this further and have it call the applet initialization so that you can launch it any way you like, I suspect this is a bit beyond what you were asking.
Does this solve your problem?

CMP entity beans from tables in 9.0.3 jdev preview

I am trying to generate CMP entity beans from oracle tables using 9.0.3 jdeveloper preview. My oracle db version is 9.2. I notice that if a table has a single column primary key, no xxxPK.java file is created. However, if the primary key is multi-column an xxxPK.java file is created. Is this correct behavior? I expected an xxxPK.java file to be created regardless of the number of columns in the primary key for the table. Has anyone else noticed this? I am new to EJB so forgive my ignorance.

Comparing to JDev 902, I think this is a much better decision. Having to change beans with a single field PK to not using a custon PK class, to avoid using that class was a pain in JDev 902. There4s little benefit in using a custom class when there4s only a single field in it... some will say that it prevents having to do majot changes to your code if the PK changes in the future and add another field. But a careful database design will void this almost completely. So having JDev 903 use a java native class is a better option in this situation. At least from my personal point of view.

Problem getting arraylist from another class

I am trying to call information about an arraylist from another class. I am using this code to call the size of an arraylist:
import java.io.*;
public class Test
    public static void main(String argv[]) throws IOException
Echo03 thing = new Echo03();
int y=thing.value();
System.out.println(y);
Echo03 thing2 = new Echo03();
int x=thing2.percent.size();
System.out.println(x);
}from another file which starts like this:
public class Echo03 extends DefaultHandler
static ArrayList<String> percent = new ArrayList<String>();
static ArrayList<String> text = new ArrayList<String>();
int a;
public int value(){
     return percent.size();
public static void main(String argv[]) throws IOException
    {The second file is based on an example piece of code from the Java website. I havent posted the whole thing, but if it is relevant then please ask.
Anyway when I run Echo03 by itself, the arraylist has a size of 2. But when I run it from the Test file, it says a size of 0. Is this because the data is not being transferred between the classes? Or is the Echo03 program not executing (and hence the arraylist is not filling up)?
How can I fix this? I have tried 2 ways of calling the data (As seen in my Test file). Neither work.

I didnt post the full bit of the code for the second one. Here it is:

Can I invoke a class that extends JAppl from another class extends JAppl

Can I invoke a class that extends JApplet from another class that extends JApplet. I need to invoke an applet then select an action which opens another applet. Thanks in advance.

Nobody is able to solve this problem, i cant even
think this things. i have hope so plz try and get
result and help.Did you understand what Sharad has said???
Yep, you can forward to specific error page from servlet when even error occured in JSP. In order to achieve you have to open jsp file from servlet say example by using reqdisp.forward.
handle exception in the part where you are forwarding. And forward to the specific error page inside catch block.

Accessing an Array List from another class

Hi, I was a member on here before, but I forgot my password and my security question is wrong.
My question is how do I access a private arraylist from a different class in the same package?
What I am trying to do is the following (hard to explain).
Make a picking client for a shop, so that when an order is recieved, the picker can click on the orders button, and view all of the current orders that have not been completed. This Pick client has its own user interface, in a seperate class from where the BoughtList array is created, in the cashier client. The boughtlist is created when the cashier puts in the product number into the cashier client and clicks buy. I seem to be having trouble accessing the list from another class. Once the order is completed the cashier clicks bought and the list is reset. There is another class in a different pagage that processes some of the functions of the order, eg newOrder().
Yes it is for Uni so I dont need / want the full answers, jist something to get started. Also please dont flame me, I have done many other parts of this project, just having trouble getting started on this one.
Here is the code for the cashier client. The code for the Pick client is almost the same, I just need to make the code that displays the orders.

(disclaimer: I did not read through your Swing code, as I find that painful)
My question is how do I access a private arraylist from a different class in the same
package?Provide a public accessor method (getMyPrivateArrayList())

CallerPrincipal when calling one sessionbean from another

Hi all,
I have a little problem when calling one sessionbean from another sessionbean. The problem is, that in the method, which is called, is used SessionContext's getCallerPrincipal().getName(). This works great from client, but from other sessionbeans getCallerPrincipal() retuns an "ANONYMOUS" principal. How can I set the correct principal (the principal from the first sessionbean)?
Thank you
My env: Glassfish 2.1.1, Netbeans 6.8, Eclipselink 2.0.0, Java 1.6.0.18
My code:
@Stateless
public class ABean implements ASessionRemote{
@Resource
SessionContext ctx;
@Override
public void aMethod(){
String name = ctx.getCallerPrincipal().getName(); // the name is ANONYMOUS, when the call is done from other sessionbean
@Stateless
public class BBean implements BSessionRemote{
@Resource
SessionContext ctx;
@EJB
private ASessionRemote aSessionBean;
@Override
public void bMethod(){
aSessionBean.aMethod();
}

"This works great from client"
What do you mean by this, i.e what sort of client are you using (stand alone app, servlet) ?
what shows up if you printout the caller principal in the calling bean ?
are the two ejbs in the same ear ?
what security meta-information are you using in ejb-jar.xml and sun-ejb-jar.xml, if any ?

Drawing from another class

I have a class Score and in that lcass I have the following method:
* Draw the score to the applet windows
* @param g The graphics object
public void draw(Graphics g, int x, int y)
calculateScore();
String stringScore = new Integer(usersScore).toString();
g.drawString(stringScore, x, y);
In my Applet class, Driver, I have a global graphics object:
Graphics gObject;
I initialize it in the paint method by sayingpublic void paint(Graphics g)
gObject = g;
But, inside the Applet when I call the method draw it doesn't work.
Then I tried
gObject = getGraphics(0But that didn't work either.
Is it possible to draw to an applet from another class?
Thanks.

I just read one of you other postings on a similiar topic. In that thread everybody is assuming you are using Swing and are giving suggestions based on that assumption.
In this thread it appears you are using AWT so I gave suggestions based on that assumption.
It would be nice if you actually asked a clear question and stated what you are doing so people don't waste time guessing what the heck you are trying to do.
Thats one reason why I always ask for demo code. So we don't waste time guessing.
If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.
And don't forget to use the [url http://forum.java.sun.com/help.jspa?sec=formatting]Code Formatting Tags so the code retains its original formatting.

Create CMP Entity Beans from Tables Wizard - Can't see any tables with DB2

Hi,
I'm trying to use the "Create CMP Entity Beans from Tables Wizard" to create an entity from a table in a DB2 database. The problem is, on page 2, I can't see any available tables. I have verified that the connection works (I can open the connection in the Navigator frame and I can see that table).
Note that if I try this wizard on an Oracle database, I can see tables.
WTF? Can someone please help?

I second the motion. I too work in an environment with centralized data management (DBA's) that create and maintain all tables under a generic schema. This has prevented me from using the Create Entity Beans from Table feature of Jdev r3 preview.
At least I can see that I'm not alone.
Thanks
When I select the "Create CMP Entity Beans from Tables Wizard," no tables or views are available to select. The JDev database connection is using an ID assigned to me.
The tables that I am looking for were created by the DBA under his ID and are therefore in that schema. He did create Public Synonyms for them, but the tables still do not show up in the wizard.
Is there a configuration step that I need to do to have those tables show up?
Tables created by a DBA and then accessed by developers using a public synonym is a very common scenario and should be supported by JDeveloper (IMO).
Thanks.
I'm using JDev 9.0.2.8.2.
