Problems with an EJB refering a class in a Resource Adapter in 8.1 to 9.2 M

Hello,
I have the following problem: I got an EAR let's say application.ear, the ear has a Resource Adapter inside, adapter.rar, the adapter has some jar files inside which are used by an EJB that is deployed on the same server, but the EJB is not able to find the required JAR files, I'm getting NoClassDefFoundError. Is that a configuration issue? It was working fine on Bea 8.1. I noticed that in the resource adapter's configuration "Global Access To Classes Enabled" is set to false, could that be the problem? If so, where can I set it to true?
Greetings
Dennis

Thanks

Is there a problem with Entity EJBs on 8.1.7?

Oracle 8.1.7 on Solaris 7:
Bean Managed persistence:
TX Attribute - Required:
UserTransaction bound into JNDI:
I have tried numerous times and numerous ways to get my Entity beans working. Ejbs that represent tables with 3 columns work fine, but another EJB with 15 columns doesn't - ejbCreate, ejbFindByPrimaryKey work fine, but whenever make some changes and subsequently commit, ejbStore doesn't execute, I even had my client sleep for 15 secs, but still nothing. I know there is a problem with deploying EJBs using JDeveloper 3.2, but I have deployed all these EJBs using deployejb command line tool on the server itself!
We are right now trying to find out whether Oracle is our right choice for EJBs, any input is highly appreciated.
Thanks in Advance.
Ashish.

Upon further investigation this is what I have found:
1. Created another EJB for the 15 column table, but this time represented just 3 of its columns - so I have 3 instance variables in the Bean, and a getter/setter method for each except a setter for the primary key.
2. Undoubtedly it worked fine.
3. Increased the number of columns to 4 and GUESS WHAT, upon calling setXXX for the newly added setter method and committing, it started failing, the value just wouldn't change in the DB. But when I call all the setXXX methods, it works just fine, I finally narrowed it down to just 1 setXXX method, if I use this method with any other setXXX methods, all the values get updated, otherwise none of them get updated.
CLEARER PICTURE:
Supposing I have the following instance variables in the Bean:
String id;
String dt;
String vol;
String price;
String beg_day;
String end_day;
and the following get/set methods
String getId()
String getDt()
String setDt()
String getVol()
String setVol()
String getPrice()
String setPrice()
String getBeg_day()
String setBeg_day()
String getEnd_day()
String setEnd_day()
Now if I do the following:
HomeInterface hm = ...JNDI lookup
UserTransaction ut = ...JNDI lookup
ut.begin();
RemoteInterface rm = hm.findByPrimaryKey("1");
rm.setBeg_day("01-DEC-00");
ut.commit();
nothing happens, the date in the underlying table is still the same, BUT.....
if I do this:
ut.begin();
rm = hm.findByPrimaryKey("1");
rm.setDt("01-DEC-00");
rm.setBeg_day("01-DEC-00");
ut.commit();
IT WORKS..... using setDt() with any other method works for that setXXX method also...
Anybody experience this at all.....
Thanks in advance for your help.
Ashish.
PS: setDt() is the last method in the stBean.java file with the maximum __method_index, does that make any difference??

Problem with Progress DB while using to connect using JDBC Adapter

Hi,
I am facing Problem with Progress DB while using to connect using JDBC Adapter. I am getting the following error in auditlog file like,
Error during database connection to the database URL jdbc:JdbcProgress:T:156.5.31.65:2545:/mfgprodev/devbadb
/devsche/i_apoext.db using the JDBC driver "com.progress.sql.jdbc.JdbcProgressDriver" : com.sap.aii.adapter.jdbc.sql.DriverManagerException: Unable to locate a suitable JDBC driver to establish a connection to URL " jdbc:JdbcProgress:T:156.5.31.65:2545:/mfgprodev/devbadb
/devsche/i_apoext.db "
I tried using the following all URLs,
1. jdbc:JdbcProgress:T:156.5.31.65:2545:i_apoext.
2. jdbc:JdbcProgress:T:156.5.31.65:2545:i_apoext.db
3.
jdbc:JdbcProgress:T:156.5.31.65:2545:/mfgprodev/devbadb
/devsche/i_apoext.
4.
jdbc:JdbcProgress:T:156.5.31.65:2545:/mfgprodev/devbadb
/devsche/i_apoext.db.
Can anyone please help me out in solving this issue.
May be the cause for this is :
1) The Wrong URL format
2) CLASSPATH is not setted properly..
Can you look more into this stuff.
Thanks,
Soorya.

Hi,
To access any database fromm XI, using the JDBC adapter, the corresponding drivers have to be installed on the XI server.
Just check this note 831162.
Also, check this PDF to install Drivers in XI,

Problem with downloading EJBs to JDeveloper

Hi,
Upon downloading EJBs to JDeveloper905, I am able to see the bean class, remote and local classes for an entity bean. However, I cannot see the Entity Bean icon (represent the entity) in the respective package in the Model.jpr. Thus, could not access to the EJB Module Editor which previously(before using SCM) can be accessed through the entity bean icon by double clicking it. Is there any other way to access the EJB Module Editor? or it's dependant on the Entity Bean icon? Same problems with the session bean downloaded from SCM.
Hope to get replies from you guys soon.
Regards,
Jo

@ondrahu
Sorry for the time you have spent assuming that the problem is at your end by re-installing software; there seems to be no issue accessing via "Update" feature in Ovi Maps application at time of this post.
As farby points out from past experience it is not uncommon that at times maps server is not available if any maintenance being carried out, so always sensible to try a few hours later before assuming the worst.
Please let us know if you still have issues in this respect.

Problem with constructors and using public classes

Hi, I'm totally new to Java and I'm having a lot of problems with my program :(
I have to create constructor which creates bool's array of adequate size to create a sieve of Eratosthenes (for 2 ->n).
Then it has to create public method boolean prime(m) which returs true if the given number is prime and false if it's not prime.
And then I have to create class with main function which chooses from the given arguments the maximum and creates for it the sieve
(using the class which was created before) and returns if the arguments are prime or not.
This is what I've written but of course it's messy and it doesn't work. Can anyone help with that?
//part with a constructor
public class ESieve {
ESieve(int n) {
boolean[] isPrime = new boolean[n+1];
for (int i=2; i<=n; i++)
isPrime=true;
for(int i=2;i*i<n;i++){
if(isPrime[i]){
for(int j=i;i*j<=n;j++){
isPrime[i*j]=false;}}}
public static boolean Prime(int m)
for(int i=0; i<=m; i++)
if (isPrime[i]<2) return false;
try
m=Integer.parseInt(args[i]);
catch (NumberFormatException ex)
System.out.println(args[i] + " is not an integer");
continue;
if (isPrime[i]=true)
System.out.println (isPrime[i] + " is prime");
else
System.out.println (isPrime[i] + " is not prime");
//main
public class ESieveTest{
public static void main (String args[])
public static int max(int[] args) {
int maximum = args[0];
for (int i=1; i<args.length; i++) {
if (args[i] > maximum) {
maximum = args[i];
return maximum;
new ESieve(maximum);
for(int i=0; i<args.length; i++)
Prime(i);}

I've made changes and now my code looks like this:
public class ESieve {
ESieve(int n) {
   sieve(n);
public static boolean sieve(int n)
     boolean[] s = new boolean[n+1];
     for (int i=2; i<=n; i++)
s=true;
for(int i=2;i*i<n;i++){
if(s[i]){
for(int j=i;i*j<=n;j++){
s[i*j]=false;}}}
return s[n];}
public static boolean prime(int m)
if (m<2) return false;
boolean x = sieve(m);
if (x=true)
System.out.println (m + " is prime");
else
System.out.println (m + " is not prime");
return x;}
//main
public class ESieveTest{
public static int max(int[] args) {
int maximum = args[0];
for (int i=1; i<args.length; i++) {
if (args[i] > maximum) {
maximum = args[i];
return maximum;
public static void main (String[] args)
int n; int i, j;
for(i=0;i<=args.length;i++)
n=Integer.parseInt(args[i]);
int maximum=max(args[]);
ESieve S = new ESieve(maximum);
for(i=0; i<args.length; i++)
S.prime(i);}
It shows an error for main:
{quote} ESieveTest.java:21: '.class' expected
int maximum=max(args[]); {quote}
Any suggestions how to fix it?

A problem with annotation @EJB

Hi,
My application uses servlet+JSP+EJB+JBOSS. I want to use a pure java object that is a singleton and within this singleton call an EJB.
I have a servlet that call a singleton:
My servlet
public class FindAdministratorForumServlet extends HttpServlet {
     private static final long serialVersionUID = 1L;
     // ======================================
     // = Entry point method =
     // ======================================
     @Override
     protected void service(final HttpServletRequest request,
               final HttpServletResponse response) throws ServletException,
               IOException {
          final int rows=3;
          int page = Integer.parseInt(request.getParameter("page"));
          List<Topic> discussionList = ListHandlerService.getForumTopics(page); My singleton :
package service;
import java.util.LinkedList;
import java.util.List;
import java.util.ListIterator;
import javax.ejb.EJB;
import sessionbean.TopicService;
import entitybean.Topic;

     private static TopicService discussionService;
    /** Récupère l'instance unique de la class Singleton.
    * Remarque : le constructeur est rendu inaccessible
    public static ListHandlerService getInstance() {
        if (null == instance) { // Premier appel
            synchronized(objetSynchrone__) {
                if (null == instance) {
                    instance = new ListHandlerService();
        return instance;
    /** Constructeur redéfini comme étant privé pour interdire
    * son appel et forcer à passer par la méthode
    private ListHandlerService() {
    public static List<Topic> getForumTopics(int page) {
         int i = 0;
          Topic topic;
          LinkedList<Topic> result = new LinkedList<Topic>();
         if (page==1) {
              listTopic = discussionService.getForumTopics();
              ListIterator<Topic> listIterator = listTopic.listIterator();
              while (listIterator.hasNext() && (i< rows)) {
                   topic = listIterator.next();
                   result.add(topic);
                   i++;
         } else {
              ListIterator<Topic> listIterator = listTopic.listIterator();
              while (listIterator.hasNext() && (i< rows*(page-1))) {
                   listIterator.hasNext();
                   i++;
              while (listIterator.hasNext() && (i< rows*page)) {
                   topic = listIterator.next();
                   result.add(topic);
                   i++;
         return result;
    public static int getSize() {
         return listTopic.size();
} In my singleton that is a pure JAVA object, the injection of my EJB with annotation @EJB doesn't seem to work. Indeed when executing, "discussionService" that should be injected and initialized, is null. Isn't it possible to inject an EJB in a pure java object which is a singleton ?
Thank you for your answers.

Is it deployed in the same application?
In they are not in the same application you need to use some other techniques. See the following thread for info:

thanks forward.

          We got resolved it through bea. This is a know problem of WLS6.1 Sp4. Bea has provided
          us with a patch, after which every thing seems to be working fine.
          Please open a case with bea mentioning the CR092146. You can read the description
          of this CR on internet.
          This will certainly solve your problem.

Problems with getWidth() and getHeight() in class Canvas

Hi,
i am developing MIDlets with Sun Studio4 One Update1 (Mobile Edition). Here is a simple example Code for my Problem:
class MyCanvas extends Canvas
    public void paint(Graphics g)
        //Clear the Display
        g.setColor(0,0,0); //black
        g.fillRect(0,0,getWidth(),getHeight());
}If i try to execute the Program with the Default Color Phone emulator included with Suns WTK2.0, everything works fine. (Ive tried to print out the results of getWidth() and getHeight() on the console, everything ok, the Displays width and height is displayed.).
The problem is, that any other emulator from WTK1.0.4_01 (included with Sun Studio4 ME) compiles and preverifies fine, but while running the application, the emulator quits with the following error:
ALERT: No such method getWidth.()I
Execution completed successfully
Anyone has an idea?
Thanks!!

Hello,
I'm having the exact same problem and I'd like to know what changes you made to your code to get it working. My class is not an inner class and is very much like yours and so follows the form:
class MyCanvas extends Canvas{
int element = getWidth()/10;
public void paint(Graphics g) {        //Clear the Display

g.fillRect(0,0,getWidth(),getHeight());
I am also using WTK104. I did not have this problem until I renamed my file. I carried the renaming throughout the rest of the file in a consistent fashion and I don't see any problems with it. Any help appreciated.

Problems with extension of generic abstract class

Hello,
I'm having some problems with the extension of a generic abstract class. The compiler tells me I have not implemented an abstract method but I think I have. I have defined the following interface/class hierarchy:
public interface Mutator<T extends Individual<S>, S> {
     public void apply( T<S> ind );
public abstract class AbstractMutator<T extends Individual<S>, S> implements Mutator<T, S> {
     public abstract void apply( T<S> ind );
}Now I implement AbstractMutator as such:
public class BinaryMutator extends AbstractMutator<StringIndividual<Integer>, Integer> {
     public void apply( StringIndividual<Integer> ind ) { ... }
}The compiler says:
BinaryMutator.java:3: ga.BinaryMutator is not abstract and does not override abstract method apply(ga.Individual<java.lang.Integer>) in ga.AbstractMutator
Why does it say the signature of the abstract method is apply(Individual<Integer>) if I have typed the superclass as StringIndividual<Integer>?
Thanks.

Yes, but the abstract method takes an arg of type <T extends Individual>. So it takes an Individual or a subclass thereof, depending on how I parameterise the class, right? StringIndividual is a subclass of Individual. So if I specify T to be StringIndividual, doesn't the method then take an arg of type StringIndividual?

Problem with jikes & EJB

I've been experiencing a problem using jikes to compile EJBs. Has anyone
has this type of problem and is there a known fix?
The beans seem to compile fine, but I get an error when trying to deploy
them. Here's the error:
weblogic.ejb.common.DeploymentException: Unexpected I/O exception during
deployment:
weblogic.ejb.common.DeploymentException: Problem deploying a bean:
java.lang.VerifyError: (class:
com/criatech/contractstation/party/provider/PartyManagerBeanEOImpl_ServiceSt
ub, method: ensureInitialized signature: ()V) Illegal target of jump or
branch
at java.lang.Class.getConstructor0(Native Method)
at java.lang.Class.getConstructor(Class.java:886)
Thoughts?

That seems to be the problem. It only happens on one bean which is a very
large one. It appears to work ok with the javac 1.3 compiler, but no luck
with jikes. It's unfortunate, because jikes is SO much faster.
At least I know someone else is seeing this problem. Thanks for the info.

Hi.
This sounds a bit like a problem we were having when compiling one of the
generated classes for a bean with a huge number of methods (~400). The
ensureInitialised method (I think, it might be a different method now -the
name of the class changes in every WLS version) got so big that some ofthe
jump instructions needed to become wide jump instructions but both javacand
jikes got it wrong.
For us, the workaround was (and still is) to use kjc(http://www.dms.at/kopi/)
to compile the generated classes.
This may or may not be your problem, however.
Toby.

Bouncing off the wall: Problems with passing/using pointers to classes

I have a mostly completed "msPaint" (=assigment) program that is driving me nuts!!!
1. First shape you draw doesn't appear.
1.5 Draw a shape by clicking twice on Panel, can change shape, color, fill with what buttons you see.
2. Subsequently only the newest shape appears. Using System.println(); it appears to be drawing as many shapes as it has made, but it doesn't.
3. I owe much to anyone who helps me, here is complete code. Specifically will ask/reward you to reply to a diff link in which I have dukes, got no answer, and can't reallocate dukes. (=5)
Thank you very much.

Sorry mate but you need a lot of work....
I like what you've done but (in my humble opinion) it needs a lot of reworking.
Your problem is you're not storing the shapes. You've set up an array but you never assign the shapes to it. I would reccomend using a vector. Heres a quick bit of pseudo code.
Listener class
mouseClicked method
if first click
get mouse x/y
if second click
get mouse x/y
create new MyShape(x1, y1, x2, y2)
call data.addShape(new MyShape)
Data class
constructor
this.myVector = new Vector()
addShape(MyShape shape) method
this.myVector.addElement(shape) -- add new shape
this.myVector.remove(0) -- remove bottom shape
drawAllShapes method
Enumeration enum= this.myVector.elements()
while(enum.hasMoreElements())
MyShape shape = (MyShape)enum.nextElement()
shape.draw()
Feel free to ask any questions.

Problem with final variables and inner classes (JDK1.1.8)

When using JDK1.1.8, I came up with following:
public class Outer
    protected final int i;
    protected Inner inner = null;
    public Outer(int value)
        i = value;
        inner = new Inner();
        inner.foo();
    protected class Inner
        public void foo()
            System.out.println(i);
}causing this:
Outer.java:6: Blank final variable 'i' may not have been initialized. It must be assigned a value in an initializer, or in every constructor.
public Outer(int value)
^
1 error
With JDK 1.3 this works just fine, as it does with 1.1.8 if
1) I don't use inner class, or
2) I assign the value in initializer, or
3) I leave the keyword final away.
and none of these is actually an option for me, neither using a newer JDK, if only there is another way to solve this.
Reasons why I am trying to do this:
1) I can't use a newer JDK
2) I want to be able to assign the variables value in constructor
3) I want to prevent anyone (including myself ;)) from changing the value in other parts of the class (yes, the code above is just to give you the idea, not the whole code)
4) I must be able to use inner classes
So, does anyone have a suggestion how to solve this problem of mine? Or can someone say that this is a JDK 1.1.8 feature, and that I just have to live with it? In that case, sticking to solution 3 is probably the best alternative here, at least for me (and hope that no-one will change the variables value). Or is it crappy planning..?

You cannot use a final field if you do not
initialize it at the time of declaration. So yes,
your design is invalid.Sorry if I am being a bit too stubborn or something. :) I am just honestly a bit puzzled, since... If I cannot use a final field in an aforementioned situation, why does following work? (JDK 1.3.1 on Linux)
public class Outer {
        protected final String str;
        public Outer(String paramStr) {
                str = paramStr;
                Inner in = new Inner();
                in.foo();
        public void foo() {
                System.out.println("Outer.foo(): " + str);
        public static void main( String args[] ) {
                String param = new String("This is test.");
                Outer outer = new Outer(param);
                outer.foo();
        protected class Inner {
                public void foo() {
                        System.out.println("Inner.foo(): " + str);
} producing the following:
[1:39] % javac Outer.java
[1:39] % java Outer
Inner.foo(): This is test.
Outer.foo(): This is test.
Is this then an "undocumented feature", working even though it shouldn't work?
However, I assume you could
get by with eliminating the final field and simply
passing the value directly to the Inner class's
constructor. if not, you'll have to rethink larger
aspects of your design.I guess this is the way it must be done.

Problem with file.listFiles() of File class??

Hi all friends,
Iam facing with one peculiar problem,Iam using [file.listfiles()] method of File class in my program and this method of file class introduced in Java2.Now when Iam runing on Mac OS classic(8 to 9)[it is my client requirement they can't change Mac OS classic to Mac OS X] it is giving me error file.listfiles() not found in java.io package coz in Mac classic I have used MRJ2.2.6(for runtime) and MRJ SDK2.2 which is based on jdk1.1.8 and this method[listfiles()] added in java2.But now for me I can't change this method in program coz it is a big code and I have to change lot of things in my program.Can any one plz tell me can i find any (java.io) package of java2 seperately in the from of .jar or .zip so that i can keep it in my MRJCLASSES folder and from there I can import it in my program.Eagerly waiting for reply.
Regards
Bikash

Just use File.list(). There are minor semantical differences but they are easy to work around.

Problems with data controls from java classes in JSF pages.

Hi! We have a problem in our Application that we are developing with JSF pages using Data Controls generated from facades java classes. When we running a page in debug mode and the page are loading, if we insert a breakpoint in the first line of method referenced in the data control, the execution enter two times in the method, and this is a problem for us. How to solve this?
We are using JDeveloper 11.1.1.2 with ADF faces.

You might need to play around with the refresh property of the action binding.
