Missing method to query a Proxy's interfaces list.

I need to query a Proxy object for its implemnting interfaces list (or array).
Following source code I see that Proxy class already detains the map proxyClasses indexed by the proxyClass that is used to check wether a class is a Proxy:
boolean isProxyClass(Class<?> cl)Following the same philosophy there should be also a method
Class<?>[] getProxyInterfaces(Class<?> cl)that returns the list of interfaces used to define the Proxy class.
This would be very useful to me.
Do you think this could be implemented, maybe already in the next builds of version 5 and/or 6 of J2SE?
Regards,
Marco.

Perhaps I am missing something. For any class cl if Proxy.isProaxyClass(cl) is true then would not cl.getInterfaces() give the list of interfaces that the class proxies?

Web Service u0096 ABAP proxy synchronous interface

hi experts,
can you suggest me how to do this scenario?
<i><b>Web Service ABAP proxy synchronous interface.</b></i>

hi,
you can create a web service on XI
which will call ABAP proxy (on ERP, SRM etc)
in a synchronous way (you just need to generate the proxy class
in TCODE SPROXY)
then you can fill the method of your generated proxy class
and you will have WS - ABAP proxy interface
have a look at this to undrstand server proxy:

Missing method body or declare abstract error

Hi!
I have been working on this simple Java 1.3.1 program for three days now and cannot figure out what I am doing wrong. If anyone has done the "Building an Application" tutorial in the New to Java Programming Center, you might recognize the code. I am trying to set up a frame with panels first using the BorderLayout and then the FlowLayout within each section of the BorderLayout. It will have textfields and checkboxes. I am working on the code to retrieve the user input from the text boxes and also to determine which checkbox the user has checked. Here is my code: (ignore my irrelivent comments!)

Query in BPS Web Interfaces - Open in New Window

Hello,
I am trying to insert a BW Query into a web interface but have it launch in a new window. I know how to have it open in the web interface by using a text box. In July of 05 I found an answer from Marc Bernard on a similar topic, but with a query returning variables. When I tried to use the code, I got an error. I know that I can create a URL with Target="_Blank" but I don't want to hard code the full URL of the web report because the default host and port will change with the systems. I tried the following URL in hopes that would inherit the system but it doesn't work.
http://<default_host>:<default_port>/sap/bw/BEx?cmd=ldoc&infocube=EPABUDGET&query=EPA322BR
Here is the code I have for the report.   Can someone tell me how to open in a new window or how to get the URL to work?
<iframe
    id="BWReport01"
    name="BWQUERY"
    src="/sap/bw/BEx?cmd=ldoc&infocube=EPABUDGET&query=EPA322BR"

Thanks,

Hi Cherie,
you are on the right track. Just use a href="/sap/bw/bex..." target="_blank". If you need the URL to be more dynamic, use javascript with window.open.

Missing operator in query expression

Greetings,
I'm attempting to access a MS Acess database, but getting the following error.
Syntax error (missing operator) in query expression 'Org Name'.
The error occurs between the following two lines.
String SQL = "SELECT Org Name FROM OrganizationTable";
ResultSet resultset = statement.executeQuery(SQL);Where Org Name is the data set I'm trying to access and OrganizationTable is the database table.
Any help would be appreciated.

What is happening is that the interpreter is seeing
"Org Name" as two different columns and/or values and
is expecting an operator. Somehow you need to
indicate that it should be interpreted as a single
column.
Try one of these (I'm not sure if one will work since
I don't work with access much, but I'm guessing that
it would work similar to other dbs I've used):
String SQL = "SELECT [Org Name] FROM
OrganizationTable";
or
String SQL = "SELECT 'Org Name' FROM
OrganizationTable";
Thanks boss,
I started to get it figured as I was able to open a result set that didn't have any whitespace in the name in the same table.
FYI, [Org Name], did the trick. Single quotes do not work.
Thanks again :)

Multiprovder objects missing in the Query Designer

Hi,
I have multiprovider based on 2 infosets ( as the reproting is based on master data) .
Later on i have added couple of objects in master data and adjusted the infoset and activated it . The multiprovider also ajusted after adding the fields.
I have activated the multiprovider which is successfully activated, but when i login to Query designer and try to create a query the news objects are missing from the query desinger where as in RSA1 for the Multiprovider it is displayed.. Kindly can anyone will help to resolve this.
Thanks

Hi Sathish,
Thanks for the response..
I have cehck the infoset invidually , the data dispalyed in both the infosets are according to my requreiment.
When i was checking the multiprovider i did not get the fileds which i have added in the multiprovider , i went back to the structure to cross check, if found this difference for all the ojects when you right click it will display assign identification filed where as for the added obejct it is displaying Change RUN id option.. why this is happening...
This is happen in test server after transprotation where as in dev it is fine and executing properly
Thanks

Error message "missing method body, or declare abstract"

This is my test driver. Does anyone know why it is not working?
public class TestInfo
   public static void main(String args[])
          Info results = new Info();
          printInfo();
     public static String printInfo();
          System.out.println(" The Diameter is: " + results.diam
          + " The Circumference is: " + results.circum
          + " The Area is: " + results.area);
}The error message I get is: missing method body, or declare abstract
The print block has to be a separate method. The print block works when I put it in main. When it is in a separate method and I call it in main it doesn't work

You have an extraneous semi-colon after printInfo. This tells the compiler that that's all there is for that method, which only makes sense if it's an abstract method. It sees the block after the semicolon, but it thinks it's an initializer. So it wants you to either declare it abstract, or give it a method body.
Just remove that semicolon and you're fine.

Wsdlc with jaxws - missing method on bean

One, at least, of the POJOs created by "wsdlc" for JAX-WS is missing a "setter" method. The "getter" exists. The corresponding "setter" is missing.
I generated a Web Service from a WSDL file using "wsdlc". I generated the JAX-RPC and JAX-WS Web Service. I compared one of the POJOs. The JAX-RPC version has the correct "getter" and corresponding "setter" methods. The JAX-WS version is missing a "setter". The code below is missing: setResponseStatusMessage.
Is there a bug in "wsdlc" related to generics?

1) Put an "action" in your form tag. The action should be either
a JSP or a servlet. e.g. <FORM name="createPerson" action="/servlet/process" method="post">2) If you use a JSP for processing then move your <jsp:useBean>
tag to the processing JSP. If you use a servlet then import the bean
class and instantiate the class.
import com.oxbow.*;
PersonBean person = new PersonBean();3) Get the parameters passed:

Java.lang.RuntimeException: Uncompilable source code - missing method body

Hi,
I am getting the following error at runtime
java.lang.RuntimeException: Uncompilable source code - missing method body, or declare abstractwhen I try to instantiate a class using reflexion as following:
MyInstance = MyClass.newInstance(); I have tried to find some explanation using Google, but could not find any that fit my case. MyClass's implementation has a public constructor with no parameter. There is no error at compile time when cleaning and building all code.
Anyone has tips about what could cause this error?
Thanks.

Missing method body

class Board
    public static void main(String[] args)
        Board example = new Board();
    private Board();
        char array[][];
        array = new char[3][3];
        for (int i = 0; i < 3; i++)
            for (int j = 0; j < 3; j++)
                array[i][j] = '.';
                System.out.println(array[i][j]);
}compiler says missing method body, but i can't think where the error is? private Board has to be a constructor.

Are you using a text editor or an IDE? If you are already fairly familiar with the Java programming language and the java/javac and you understand how classpath works, then you might consider to step over from the text editor to an IDE, such as Eclipse. It will save time and effort in developing. I tried to reproduce your problem in Eclipse and it clearly understrikes the "Board();" part during typing and says "This method requires a body instead of a semicolon" which makes much more sense.

Missing method body and cannot resolve symbol

I keep getting these two errors when trying to compile. I know that I need to call my fibonacci and factorial functions from the main function. Is this why I am getting the missing method body error? How do I correct this?
Am I getting the cannot resolve symbol because I have to set the num and fact to equal something?
Thanks
public class Firstassignment
public static void main(String[]args)
     System.out.println();
public static void fibonacci(String[]args);
     int even=1;
     int odd=1;
     while (odd<=100);
     System.out.println(even);
     int temp = even;
     even = odd;
     odd = odd + temp;
public static void factorial (String[]args);
     for (int count=1;
     count<=num;
     count++);
     fact = fact * count;
     outputbox.printLine("Factorial of" + num + "is" + fact);

Hey... :o)
the problem is that you've put semicolons at the end of the function signature, like this:
public static void fibonacci(String[]args);
}that should happen only when the function is abstract... so ur function should actually look like this:
public static void fibonacci(String[]args)
}also, i think you've missed out on the declarations (like what are fact and num??)....

Missing method body or declare abstract...

Hi There,
Im working on an assignment that works with the math class and performs a bunch of mathematical functions. Im trying to declare the different fields in the math class and I keep getting error messages!!
This is what I have right now
public class Math
    // Returns the absolute value of a double value.
    double abs(double a);
    // Returns the absolute value of a int value.
    int abs(int a);
    //Returns the greater of two double values.
    double max(double a, double b);
    //Returns the greater of two int values.
    int max(int a, int b);
    // Returns the lesser of two double values.
    double min(double a, double b);
    // Returns the lesser of two double values.
    int min( int a, int b);
    // Returns the value of the first argument raised to the power of
    // the second argument.
    double pow(double a, double b);
    // Returns the remainder of division of two integers.
    int remainder(int a, int b);
    // Returns the closest long to the argument.
    long round(double a);
    // Returns the sum of all the elements in an array of doubles.
    double sum(double [] doubleArr);
    // Returns the sum of all the elements in an array of ints.
    int sum(int [] intArr);
    // Storage for the list of integers used for the int sum method.
    private int [] intArray = {5, 10, 15, 20};
    // Storage for the list of doubles to be used double sum method.
    private double [] doubleArray = {5.25, 10.00, 14.50, 21.90};
    }When I try and compile it tells me that Im missing method body or declare abstract.
I originally had this
   // Returns the absolute value of a double value.
    double abs;
    // Returns the absolute value of a int value.
    int abs;
    //Returns the greater of two double values.
    double max;

    // Returns the lesser of two double values.
    double min;
    // Returns the lesser of two double values.
    int min;
    // Returns the value of the first argument raised to the power of
    // the second argument.
    double pow;
    // Returns the remainder of division of two integers.
    int remainder;
    // Returns the closest long to the argument.
    long round;
    // Returns the sum of all the elements in an array of doubles.
    double sum(double [] doubleArr);
    // Returns the sum of all the elements in an array of ints.
    int sum(int [] intArr);
    // Storage for the list of integers used for the int sum method.
    private int [] intArray = {5, 10, 15, 20};
    // Storage for the list of doubles to be used double sum method.
    private double [] doubleArray = {5.25, 10.00, 14.50, 21.90};When i tried doing this it told me that I had already declared the field previously when it got the the field with the same name and thats why I added the bit in brackets.....
Im so lost... can anybody hep????

hi,
here is your code...
modified by correcting my bad habit...
he..he...
public class Math
    // Returns the absolute value of a double value.
    double abs(double a){return 0.0;}
    // Returns the absolute value of a int value.

    double min(double a, double b){return 0.0;}
    // Returns the lesser of two double values.
    int min( int a, int b){return 0;}
    // Returns the value of the first argument raised to the power of

    // Storage for the list of doubles to be used double sum method.
    private double [] doubleArray = {5.25, 10.00, 14.50, 21.90};
    }if you want to extend Math class to any other class.. then make all the methods abstract

Unable to call exported client methods of EJB session bean remote interface

I am unable to call client methods of a BC4J application module deployed as a Session EJB to Oracle 8i at the client side of my multi-tier application. There is no documentation, and I am unable to understand how I should do it.
A business components project has been created. For instance, its application module is called BestdataModule. A few custom methods have been added to BestdataModuleImpl.java file, for instance:
public void doNothingNoArgs() {
public void doNothingOneArg(String astr) {
public void setCertificate(String userName, String userPassword) {
theCertificate = new Certificate(userName, userPassword);
public String getPermission() {
if (theCertificate != null)
{if (theCertificate.getPermission())
{return("Yes");
else return("No, expired");
else return("No, absent");
theCertificate being a protected class variable and Certificate being a class, etc.
The application module has been tested in the local mode, made remotable to be deployed as EJB session bean, methods to appear at the client side have been selected. The application module has been successfully deployed to Oracle 8.1.7 and tested in the remote mode. A custom library containing BestdataModuleEJBClient.jar and BestDataCommonEJB.jar has been created.
Then I try to create a client basing on Example Oracle8i/EJB Client snippet:
package bestclients;
import java.lang.*;
import java.sql.*;
import java.util.*;
import javax.naming.*;
import oracle.aurora.jndi.sess_iiop.*;
import oracle.jbo.*;
import oracle.jbo.client.remote.ejb.*;
import oracle.jbo.common.remote.*;
import oracle.jbo.common.remote.ejb.*;
import oracle.jdeveloper.html.*;
import bestdata.client.ejb.*;
import bestdata.common.ejb.*;
import bestdata.common.*;
import bestdata.client.ejb.BestdataModuleEJBClient;
public class BestClients extends Object {
static Hashtable env = new Hashtable(10);
public static void main(String[] args) {
String ejbUrl = "sess_iiop://localhost:2481:ORCL/test/TESTER/ejb/bestdata.BestdataModule";
String username = "TESTER";
String password = "TESTER";
Hashtable environment = new Hashtable();
environment.put(javax.naming.Context.URL_PKG_PREFIXES, "oracle.aurora.jndi");
environment.put(Context.SECURITY_PRINCIPAL, username);
environment.put(Context.SECURITY_CREDENTIALS, password);
environment.put(Context.SECURITY_AUTHENTICATION, ServiceCtx.NON_SSL_LOGIN);
BestdataModuleHome homeInterface = null;
try {
Context ic = new InitialContext(environment);
homeInterface = (BestdataModuleHome)ic.lookup(ejbUrl);
catch (ActivationException e) {
System.out.println(e.getMessage());
e.printStackTrace();
System.exit(1);
catch (CommunicationException e) {
System.out.println(e.getMessage());
e.printStackTrace();
System.exit(1);
catch (NamingException e) {
System.out.println(e.getMessage());
e.printStackTrace();
System.exit(1);
try {
System.out.println("Creating a new EJB instance");
RemoteBestdataModule remoteInterface = homeInterface.create();
// Method calls go here!
// e.g.
// System.out.println(remoteInterface.foo());
catch (Exception e) {
System.out.println(e.getMessage());
e.printStackTrace();
It doesnt cause any errors. However, how must I call methods? The public interface RemoteBestdataModule has no such methods:
void doNothingNoArgs();
void doNothingOneArg(java.lang.String astr);
void setCertificate(java.lang.String userName, java.lang.String userPassword);
java.lang.String getPermission();
Instead of that it has the following methods:
oracle.jbo.common.remote.PiggybackReturn doNothingNoArgs(byte[] _pb) throws oracle.jbo.common.remote.ejb.RemoteJboException, java.rmi.RemoteException;
oracle.jbo.common.remote.PiggybackReturn doNothingOneArg(byte[] _pb, java.lang.String astr) throws oracle.jbo.common.remote.ejb.RemoteJboException, java.rmi.RemoteException;
oracle.jbo.common.remote.PiggybackReturn customQueryExec(byte[] _pb, java.lang.String aQuery) throws oracle.jbo.common.remote.ejb.RemoteJboException, java.rmi.RemoteException;
oracle.jbo.common.remote.PiggybackReturn setCertificate(byte[] _pb, java.lang.String userName, java.lang.String userPassword) throws oracle.jbo.common.remote.ejb.RemoteJboException, java.rmi.RemoteException;
oracle.jbo.common.remote.PiggybackReturn getPermission(byte[] _pb) throws oracle.jbo.common.remote.ejb.RemoteJboException, java.rmi.RemoteException;
I cannot call those methods. I can see how they are called in BestdataModuleEJBClient.java file:
public void doNothingNoArgs() throws oracle.jbo.JboException {
try {
oracle.jbo.common.remote.PiggybackReturn _pbRet = mRemoteAM.doNothingNoArgs(getPiggyback());
processPiggyback(_pbRet.mPiggyback);
if (_pbRet.isReturnStreamValid()) {
return;
catch (oracle.jbo.common.remote.ejb.RemoteJboException ex) {
processRemoteJboException(ex);
catch (java.rmi.RemoteException ex) {
processRemoteJboException(ex);
throw new oracle.jbo.JboException("Marshall error");
However, I cannot call getPiggyback() function! It is a protected method, it is available to the class BestdataModuleEJBClient which extends EJBApplicationModuleImpl, but it is unavailable to my class BestClients which extends Object and is intended to extend oracle.jdeveloper.html.WebBeanImpl!
It seems to me that I mustnt use RemoteBestdataModule interface directly. Instead of that I must use the public class BestdataModuleEJBClient that extends EJBApplicationModuleImpl and implements BestdataModule interface. It contains all methods required without additional arguments (see just above). However, how must I create an object of BestdataModuleEJBClient class? That is a puzzle. Besides my custom methods the class has only two methods:
protected bestdata.common.ejb.RemoteBestdataModule mRemoteAM;
/*This is the default constructor (do not remove)*/
public BestdataModuleEJBClient(RemoteApplicationModule remoteAM) {
super(remoteAM);
mRemoteAM = (bestdata.common.ejb.RemoteBestdataModule)remoteAM;
public bestdata.common.ejb.RemoteBestdataModule getRemoteBestdataModule() {
return mRemoteAM;
It looks like the remote application module must already exist! In despair I tried to put down something of the kind at the client side:
RemoteBestdataModule remoteInterface = homeInterface.create();
BestdataModuleEJBClient dm = new BestdataModuleEJBClient(remoteInterface);
dm.doNothingNoArgs();
Of course, it results in an error.
System Output: null
System Error: java.lang.NullPointerException

System Error: void bes
System Error: tclients.BestClients.main(java.lang.String[]) (BestClients.java:76)
I have studied a lot of documents in vain. I have found only various senseless discourses:
"Use the Application Module Wizard to make the Application Module remotable and export the method. This will generate an interface for HrAppmodule (HrAppmodule.java in the Common package) which contains the signature for the exported method promoteAllEmps(). Then, deploy the Application Module. Once the Application Module has been deployed, you can use the promoteAllEmps() method in your client-side programs. Calls to the promoteAllEmps() method in client-side programs will result in calls to the promote() method in the application tier."
However, I have failed to find a single line of code explaining how it should be called.
Can anybody help me?
