Wscompile NullPointerException
Hello, I am trying to create java classes from wsdl but I failed to use wscompile.bat properly. First, I deleted from wscompile.bat the last parameter for "%JAVA_HOME%\bin\java.exe" classpath which was "%PATH%", because it was showing just the java.exe help. Next, I created a config file for my WSDL which looks like:
<?xml version="1.0" encoding="UTF-8" ?>
<configuration
xmlns="http://java.sun.com/xml/ns/jax-rpc/ri/config">
<wsdl
location="http://marvin:7778/esb/wsil/EDC/EDC?wsdl"
packageName="mypackage"/>
</configuration> And finally I ran "wscompile -Xprintstacktrace -d build -gen wsdl_config.xml" which returned a NullPointerException:

Hi
I have also tried to run wscompile through maven instead of Ant and get the exact same exception in the
'com.sun.xml.rpc.util.JavaCompilerHelper.internalCompile(JavaCompilerHelper.java:45)'. The java source gets generated(ties/etc) but the compilation doesnt happen because of this. This is with J2sdk1.4.2_01 and Maven-beta-9. Please help.

I�m trying to use a bean as return type from a web service method, but I get an error:
deserialization error: java.lang.NullPointerException
this is the class consuming the web service
package local.jws;
import local.jws.remote.TestBeanIF;
import local.jws.remote.TestBean;
import java.io.*;
import java.net.URL;
import javax.xml.rpc.Service;
import javax.xml.rpc.ServiceException;
import javax.xml.rpc.ServiceFactory;
import javax.xml.namespace.QName;
public class Client implements java.io.Serializable
private TestBean tb;
private String somestring;
public Client()
try
String wsURL = "http://localhost:8080/webservice/testbean?WSDL";
String nameSpaceURI = "http://local.jws/wsdl/MyTestBean";
String portName = "TestBeanIFPort";
String serviceName = "MyTestBean";
URL serviceURL = new URL( wsURL );
ServiceFactory serviceFactory = ServiceFactory.newInstance();
QName qServiceName = new QName( nameSpaceURI, serviceName );
Service ws = serviceFactory.createService( serviceURL, qServiceName );
QName qPortName = new QName( nameSpaceURI, portName );
TestBeanIF myTestBeanIF = (TestBeanIF)ws.getPort( qPortName, local.jws.remote.TestBeanIF.class );
somestring = myTestBeanIF.getString();
tb = myTestBeanIF.getTestBean( "hello bean" );
catch( Exception ex )
public TestBean getTb()
return this.tb;
public void setTb( TestBean tb )
this.tb = tb;
public String getSomestring()
return this.somestring;
public void setSomestring( String value )
this.somestring = value;
this is the bean:
package local.jws.beans;
public class TestBean implements java.io.Serializable
private String test;
public TestBean(){ }
public String getTest()
return test;
public void setTest( String value )
this.test = value;
this is the interface implementation:
package local.jws;
import local.jws.beans.TestBean;
public class TestBeanImpl implements TestBeanIF
public TestBean getTestBean( String value )
TestBean tb = new TestBean();
tb.setTest( value );
return tb;
public String getString()
return "some string";
using the getString() method works fine but getTestBean() doesn�t;
any clue on this?
thanksHi,
I'm experiencing exactly the same problem as you ...
The only fix I found is to use static invocation ... with static invocation, WSCompile generates a deserializer and everything works fine, no mure NullPointer exception ...
With dynamic invocation as you are trying to manage here, I didn't find any way to tell the client to use the deserializer generated with wscompile ...
Does anyone know how to do it ?
Thanks,

Hi,
I'm getting the following error when running wscompile from the command line (it also occurs when I run it from the Utilities GUI):
error: Unknown QName of member 'name'
error: java.lang.NullPointerException
When I run the same WSDL file through the version of wscompile that comes with version 1.6 of the JWSDP, everything works fine, and all the code gets generated.
A further issue is that my WSDL file contains nothing named 'name' (with a small 'n'). There are some elements and attributes called 'Name', however and I suspect that it's one of the attributes that's causing a problem, although that's not based on anything solid.
Any suggestions as to how to fix this would be greatly appreciated!

Is wscompile compatible with OC4J?
Hi everyone. I have a very simple Java class:
public class Echo
public String sayIt(String input)
return input + " " + input;
}There is also a matching remote interface. When I create the WSDL and JAX-RPC mapping file using Sun's wscompile tool, I can deploy the resulting Web Service in a WAR file to JBoss with no problem, but OC4J rejects it with the following error:
WARNING java.lang.InstantiationException:
Error compiling :C:\oracle\OC4J10.1.3\j2ee\home\applications\soasta\concerto:

Wsimport throws NullPointerException
I've created a small web service, and I'm trying to generate the client using the wsimport tool. I'm getting the exception below.
Hints:
- We have many similar services that wsimport is working fine with.
- I've tried to call this WS using the Microsoft InfoPath, and it worked fine.
What is possibly causing this exception?

Hi all,
I have made a small code (just an interface and it's implementation)for JAX-RPC API.

then i have used WSCOMPILE tool as
wscompile -cp ../* -gen server config.xml.
an exception coming as
error:modeller error:java.lang.NullPointerException.
anyone expereince?.plz tell me the issues with wscompile tool.Please post JAXRPC related questions to [email protected]
Can you include the entire stack trace? -
Sender Mail Adapter - java.lang.NullPointerException in CC monitoring
hi,
I configured my Sender Mail Adapter correctly.
I have the correct POP URL, authentication. I'm not using PayloadSwapBean right now.
I can't get rid of the exception inside my Channel monitoring.
exception caught during processing mail message; java.lang.NullPointerException
does anyone know why?
I've been told the POP account has emails already.
I will try to create an outlook account for this POP e-mail account in the mean time to see the e-mails.
Thank youthanks aaron.
I don't see the folder ./SYS/../j2ee/...
will it be under another folder? I don't see a trace log folder either.
I think the problem might be in the Module tab.
I tried.
AF_Modules/PayloadSwapBean
localejbs/AF_Modules/PayloadSwapBean
/localejbs/AF_Modules/PayloadSwapBean
sap.com/com.sap.aii.adapter.mail.app/XIMailAdapterBean
localejbs/sap.com/com.sap.aii.adapter.mail.app/XIMailAdapterBean
/localejbs/sap.com/com.sap.aii.adapter.mail.app/XIMailAdapterBean
they all produce the same error. I wonder if these Beans actually exist.
I think we might have to reinstall this Mail Adapter altogether.
Or maybe it's really the connection to the Mail Server. But would it display this kind of message.
This is what I'm looking at.
Also, i had to use this URL
pop://server:995/
(995 is using SSL and it is the default port). When I use this, I see the Java Null Pointer Exception a lot less frequently. Weird. -
Data Federator Connection to R3 - java.lang.NullPointerException
Hi.
We are trying to add a SAP R3 DataSource in Data Federator XI 3.0 SP2.
Test Connection gives us the following message: "The connection was established but there is no table for the given connection parameters", what it seems to be ok according to the SAP doc.
However, when we try to get a list of the Functions or Infosets in the SAP system, an error comes because of a "java.lang.NullPointerException". Checking the application log we get the following:

Are there any ideas? Thanks -

Am i doing anything wrong in the code? Where can this nullpointerexception be triggered?
Thanks.These three xml are the same:
<?xml version="1.0"?><a:xml xmlns:a="urn:123">root</a:xml>
<?xml version="1.0"?><xml xmlns="urn:123">root</xml>
<?xml version="1.0"?><ns0:xml xmlns:ns0="urn:123">root</ns0:xml>
But your code will work only with last one, because it doesn't bound namespace to prefix ns0. -
HI Everyone!
I try to deploy my web dynpro project to SAP J2EE engine. Configuration about SAP J2EE Engine is OK, but there is an error during the deployment. Here is the deployment trace:

It seems that there is something wrong about 'SDU', but i don't know what is it, and i can not find the answer both in sdn.sap.com and here.
Anyone can help me on this?
Thanks in Advance,
MKHi Sumit,

Getting java.lang.NullpointerException while closing resultset aft using it
Hi,
I kindly request to share your ideas reg. my problem.
I am opening a database connection using connection pool and i am using two or more resultsets and statement objects.I am closing these objects at the end of their usage.But i am getting java.lang.NullpointerException when i close them(if i don't close them it works fine). what might be the reason. Had i did any thing wrong in the code.
please view the code

Prasanth.CThanks a lot.
i replaced the code below
if (rs != null)
try
rs.close();
catch (SQLException e)
rs = null;
if (rs1 != null)
try
rs1.close();
catch (SQLException e)
rs1 = null;
if (rs2 != null)
try
rs2.close();
catch (SQLException e)
rs2 = null;
if (rs3 != null)
try
rs3.close();
catch (SQLException e)
rs3 = null;
if (st != null)
try
st.close();
catch (SQLException e)
st = null;
if (pst != null)
try
pst.close();
catch (SQLException e)
pst = null;
instead of blindly closing the resultsets and statements
now it works fine.
One more thing, is my code structurally correct, i mean the variables, try...catch blocks,results,statements,database connections and overall coding. whether it looks like professional code.
thaks & regards,

Help with "Exception in thread "Thread-4" java.lang.NullPointerException"
I am new to Java and I am trying a simple bouncing ball example from Stanford. Here is their simple example that works.
import acm.program.*;

import java.awt.*;
public class BouncingBallWorking extends GraphicsProgram {
/** sets diameter */
private static final int DIAM_BALL = 30;
/** amount y velocity is increased each cycle */

private static final int DELAY = 50;
/** Initial X and Y location ball*/
private static final double X_START = DIAM_BALL / 2;
private static final double Y_START = 100;
private static final double X_VEL = 3;
private static final double BOUNCE_REDUCE = 0.9;
private double xVel = X_VEL;
private double yVel = 0.0;
private GOval BallA;

// Simulation ends when ball goes off right hand
// end of screen
while (BallA.getX() < getWidth()) {

yVel = - yVel * BOUNCE_REDUCE;
double diff = BallObject.getY() - (getHeight() - DIAM_BALL);
BallObject.move(0, -2 * diff);
} Now I am trying to modify "setup" so it I can create several balls. I made a simple modification to "setup" and now I am getting an error.

That is great! Thanks. I've got two question though.
1.) Now I want to have 100 bouncing balls. Is the best way to achieve this is through an array of GOvals? I haven't gotten to the lecture on arrays on Stanford's ITunesU site yet so I am not sure what is possible with what I know now.An array would work, or a List. But it doesn't matter much in this case.
2.) Are references being passed by value only applicable to Java or is that common to object-oriented programming? Also is there a way to force Java to pass in "BallA" instead of the value "null"?I can't say about all OO languages as a whole, but at least C++ can pass by reference.
And no, there's no way to pass a reference to the BallA variable, so the method would initialize it and it wouldn't be null anymore.
When you call the method with your BallA variable, the value of the variable is examined and it's passed to the method. So you can't pass the name of a variable where you'd want to store some object you created in the method.
But you don't need to either, so there's no harm done. -
I have classes CDRack, Record and TestProgram.
When I am trying to run TestProgram I have runtime error:

public boolean insert(Record disc,

}I suspect it is the line that reads
if (collection[slot].equals(null))
If the array entry at collection[slot] is null this will indeed cause a NullPointerException. If you are trying to test for a null entry, which is what it looks like you need to do it like this
if (collection[slot] == null) -
Hello, I hope you can help me out with a Java excercise I am working on. I am using "Learn to Program with Java by John Smiley.
It involves error checking to see if the user clicks cancel without sending a required string or sending an empty string on a JOptionPane
prompt.
If you look at the code you will see what I mean. On my machine
it compiles fine. But when I run it, instead of returning a string with
message "You clicked on CANCEL button" or you sent an empty screen the program bombs
Specifically when click Cancel I get
NullPointerException error.
When I click OK on an empty string the program bombs black screen without any error messages.
Here is the code:
import javax.swing.JOptionPane;
class Excercise6_1
static double adjustment=0;
static double balance =0;
static double newBalance=0;
public static void main(String args[])
String response;
String moreBankingBusiness;
moreBankingBusiness=JOptionPane.showInputDialog
("Do you want to do some banking?");
moreBankingBusiness=moreBankingBusiness.toUpperCase();
while(moreBankingBusiness.equals("YES"))
response=JOptionPane.showInputDialog
("***Select Banking Options***\n\n"+
"1 for deposit" + "\n"+"2 for withdrawal"+
"\n" +"3 for balance query");
response=JOptionPane.showInputDialog
("Enter subject number,(English:1,Maths:2,Science:3");
if(response==null)
JOptionPane.showMessageDialog
(null,"You clicked CANCEL");
System.exit(0);
else if(response.equals(""))
JOptionPane.showMessageDialog
(null,"You sent and empty string");
System.exit(0);
}// end of while
} // end of main
}// end of class
The curious thing is that the program actually worked initially which lead me to think it had to do with SDK getting corrupt.
I have reinstalled JDK and the IDE JCreator several times and still get
the same problem.
Would you be kind enough to provide some insight into the problem.?
I thank you in advance for your support and co-operation.
Regards
SSThe solution is already given but why it doesn't happen when pressed ok is because at that condition it returns an empty string i.e("") whereas if you press cancel it returns a null value.Try replacing the code below and you can understand everything.
try
moreBankingBusiness=JOptionPane.showInputDialog
("Do you want to do some banking?");
if(moreBankingBusiness.equals(""))
System.out.println("empty String");
System.exit(0);
moreBankingBusiness=moreBankingBusiness.toUpperCase();
catch(NullPointerException e)
System.out.println("we caught it");
System.exit(0);
