Double check the method name you are mentioning here is the same which you have used in AM or not.
Thanks

After running the page I am getting "No method with signature - initProfiles()" in the page .
Please help me to resolve this error
Thanks
Uma.Uma,
try to delete all class files, recompile and run! Also, check if any CO is not extended other than from OAControllerImpl, although it would not be generally.

No method with signature -initPaymentMethodLOVVO()
Hi,
I have extended a CO and calling an AM which have one method xxxxxLOVVO().
I have compiled the CO code and AM code without error.
However when I run the page , I am getting the error on top of the page . The error says "No method with signature No method with signature - xxxxLOVVO()"
How do I debug this error.
Thanks in advance

I appreciate the effort all you guys putting by looking into the matter. I am putting the code as its there (in the below screen), this is one which gets compiled earlier and errored out during page run ( with the top left of screen showing No method with signature -initPaymentMethodLOVVO())
In the processRequest method in the CO, I am using follwoing lines of code
public void processRequest(OAPageContext pageContext, OAWebBean webBean)
super.processRequest(pageContext, webBean);
SSHRParams sshrparams = new SSHRParams(pageContext.getRootApplicationModule());
String asgid = pageContext.getParameter("pAssignmentId");
int asg_id=Integer.parseInt(asgid);
OAApplicationModule oa =(OAApplicationModule) pageContext.getApplicationModule(webBean);
OADBTransaction oadbtransaction=oa.getOADBTransaction();
Configuration configuration = (Configuration)oadbtransaction.findObject(Constants.CFG_REFERENCE);
String effdate =sshrparams.getEffectiveDate();
String s = configuration.getTerritoryCode();
String payid = configuration.getPayrollId();
int pay_id=Integer.parseInt(payid);
String bgid = configuration.getBusinessGroupId();
int busgrp_id=Integer.parseInt(bgid);

oraclecallablestatement.execute();
l_payroll_id = oraclecallablestatement.getString(5);
oraclecallablestatement.close();
} catch(SQLException exception){
l_payroll_id = "0";
if(!l_payroll_id.equals("0"))
Serializable[] param = {l_payroll_id,bgid,effdate};
am.invokeMethod("initXXPaymentMethodLOVVO",param);
else
Serializable[] param = {payid,bgid,effdate};
am.invokeMethod("initXXPaymentMethodLOVVO",param);
and in the AM I am using
public void initXXPaymentMethodLOVVO(String payroll_id,String busgrp,String effdate) {
XXPaymentMethodLOVVOImpl xxvo = getXXPaymentMethodLOVVO1();
xxvo.setWhereClauseParams(null);
xxvo.setWhereClause(null);
xxvo.setWhereClauseParam(1,payroll_id);
xxvo.setWhereClauseParam(2,busgrp);
xxvo.setWhereClauseParam(3,effdate);
xxvo.executeQuery();
Sorry for all the confusion earlier . -
Semantic Error: No accessible method with signature
HI,
I am trying to set the sender address as below.
MimeMessage msg = new MimeMessage( session );
// Set message attributes
msg.setFrom( new InternetAddress( fromAddress ) );
Address add = new InternetAddress("[email protected]");
msg.setSender(add);
But I am getting compile time error :
Semantic Error: No accessible method with signature "setSender(javax.mail.Address)" was found in type "javax.mail.internet.MimeMessage".
Seeing the jar file, setSender( Address xxx ) is definetly present. But I see this error. Any ideas why is this error?
Thanks.Hi Shreevatsa
You can try like this
IN CO
YourAMImpl am = (YourAMImpl)pageContext.getApplicationModule(webBean);
Number citemVerId = am.saveFileToDB(s1, s2, s3, s4, blobdomain, n1);Hope it helps!!!

JSR 172: error while invoking methods with the same signature
Hi
I am facing a peculiar problem which is not making sense to me. This is what I have done:
1. Written a simple web service that has two methods: sayHello and sayHellToMe. Both these methods have same signatures. They do not take in any parameter and return a string.
2. Deployed this web service (document/literal) type on Axis 1.2
3. Generated the stub classes from the wsdl file using Sun Wireless Toolkit's Stub Generator
4. I have now written a MIDlet that uses this stub class to invoke both the methods one after the other.
I enabled SOAPMonitor on Axis and saw the SOAP Request and SOAP Response messages. I observed the following:
1. In the first method: sayHello - everything works fine (with a few tweaks in the Stub class)
2. However, while invoking the second method sayHelloToMe, the SOAP Body tag in the SOAP Request does not contain any method name. I checked out the Stub class, the qnames and the types are all correct..
I also realized that this behavior is seen only when I have methods with the same signature in the web service. Any idea why this might be happening? It seems like a very weird problem.
Any help in this regard will be greatly appreciated.
Thanks,
AratiHi, I'm closing this thread and opening the same in another as the content got pasted in reader un friendly format and i'm unable to change the format.

No event method with matching name and signature found on EventSet
Dear,
I have this error in the Problems view in Workshop (I'm using the Weblogic 9.2.1) :
No event method with matching name and signature found on EventSet: com.bea.control.TaskControl.Callback.
This error occurs sometimes when I put an event on a task in a process definition. Example, I have a process : Application.java, when I put the onReceptionCompleted control (receive) in my process, the error appears!
Thanks for your help,
Regards,
MathieuIt is a problem with the drap & drop in Workshop (from the taskControl to the Process). Workshop automatically inserts a wrong eventSet instead of the good one from the generated task control !
See you,

A question about a method with generic bounded type parameter
Hello everybody,
Sorry, if I ask a question which seems basic, but
I'm new to generic types. My problem is about a method
with a bounded type parameter. Consider the following
situation:
abstract class A{ }
class B extends A{ }
abstract class C
public abstract <T extends A> T someMethod();
public class Test extends C
public <T extends A> T someMethod()
return new B();
}What I want to do inside the method someMethod in the class Test, is to
return an instance of the class B.
Normally, I'm supposed to be able to do that, because an instance of
B is also an instance of A (because B extends A).
However I cannot compile this program, and here is the error message:
Test.java:16: incompatible types
found : B
required: T
return new B();
^
1 errorany idea?
many thanks,Hello again,
First of all, thank you very much for all the answers. After I posted the comment, I worked on the program
and I understood that in fact, as spoon_ says the only returned value can be null.
I'm agree that I asked you a very strange (and a bit stupid) question. Actually, during recent months,
I have been working with cryptography API Core in Java. I understood that there are classes and
interfaces for defining keys and key factories specification, such as KeySpec (interface) and
KeyFactorySpi (abstract class). I wanted to have some experience with these classes in order to
understand them better. So I created a class implementing the interface KeySpec, following by a
corresponding Key subclass (with some XOR algorithm that I defined myself) and everything was
compiled (JDK 1.6) and worked perfectly. Except that, when I wanted to implement a factory spi
for my classes, I saw for the first time this strange method header:
protected abstract <T extends KeySpec> T engineGetKeySpec
(Key key, Class<T> keySpec) throws InvalidKeySpecExceptionThat's why yesterday, I gave you a similar example with the classes A, B, ...
in order to not to open a complicated security discussion but just to explain the ambiguous
part for me, that is, the use of T generic parameter.
The abstract class KeyFactorySpi was defined by Sun Microsystem, in order to give to security
providers, the possibility to implement cryptography services and algorithms according to a given
RFC (or whatever technical document). The methods in this class are invoked inside the
KeyFactory class (If you have installed the JDK sources provided by Sun, You can
verify this, by looking the source code of the KeyFactory class.) So here the T parameter is a
key specification, that is, a class that implements the interface KeySpec and this class is often
defined by the provider and not Sun.
stefan.schulz wrote:
>
If you define the method to return some bound T that extends A, you cannot

The definition of T as is does not make sense at all.>
He is absolutely right about that, but the problem is, as I said, here we are
talking about the implementation and not the invocation. The implementation is done
by the provider whereas the invocation is done by Sun in the class KeyFactory.
So there are completely separated.
Therefore I wonder, how a provider can finally impelment this method??
Besides, dannyyates wrote

Find whoever wrote the signature and shoot them. Then rewrite their code.
Actually, before you shoot them, ask them what they were trying to achieve that
is different from my first suggestion!
>
As I said, I didn't choose this method header and I'm completely agree
with your suggestion, the following method header will do the job very well
protected abstract KeySpec engineGetKeySpec (Key key, KeySpec key_spec)
throws InvalidKeySpecException and personally I don't see any interest in using a generic bounded parameter T
in this method header definition.
Once agin, thanks a lot for the answers. -
Can't fill ByteArray in EJB-Method with generated Model-Class from WD-Model
Hello everybody,
i try to call an ejb-method with data from an FileUpload-UI-Element in WD. The EJB-Method is receiving the byte-data to create a document in KM via a Web-Service.
The ebj-methid has the following signature:
public FObject putFileDataSimple (byte [] btContent, String fullFileName, String username, String password)
After importing the Model and creating a context node i have the following structure:
Request_X_putFileDataSimple
+---btContent (Node)
+-- item
+ fullFileName
+ username
+ password
btContent is of the generated Type Byte_Item, which is itself a generated Model-Class of modelClassType ARRAY
item is of Type byte
But i simply have problems to fill the context node (or the binded model-object). i tried different ways and looked at thread [https://www.sdn.sap.com/irj/scn/thread?messageID=1954223] but i cant get it work.
So my Method in WD looks like this to fill the structure and start the ejb-method:
public boolean putKMDataSimple( com.sap.tc.webdynpro.services.sal.datatransport.api.IWDResource fin ) {
try
wdContext.currentRequest_X_putFileDataSimpleElement().setFullFileName("abc");
wdContext.currentRequest_X_putFileDataSimpleElement().setUsername("def");
wdContext.currentRequest_X_putFileDataSimpleElement().setPassword("xxx");
byte[] buffer = new byte[1];
InputStream in = fin.read(false);
int i = 1;
int j = 0;
while (i!=-1)
i = in.read(buffer);
if (i!=-1)
Byte_Item bi = new Byte_Item(mAlf); // mAlf ist global defined Model-Class-Instance
bi.setItem(buffer[0]);
wdContext.currentRequest_X_putFileDataSimpleElement().modelObject().addBtContent(bi);
wdContext.currentRequest_X_putFileDataSimpleElement().modelObject().execute();
Doing this results in Error-Messages like:
Model-Object is not a complex type for every byte added this way.
And finally an IllegalArgumentException at java.lang.reflect.Array.set(Native Method)
The second way i tried is:
public boolean putKMDataSimple( com.sap.tc.webdynpro.services.sal.datatransport.api.IWDResource fin ) {
try
wdContext.currentRequest_X_putFileDataSimpleElement().setFullFileName("abc");
wdContext.currentRequest_X_putFileDataSimpleElement().setUsername("def");
wdContext.currentRequest_X_putFileDataSimpleElement().setPassword("xxx");
byte[] buffer = new byte[1];
ArrayList<Byte> btlist = new ArrayList<Byte>();
InputStream in = fin.read(false);
int i = 1;
int j = 0;
while (i!=-1)
i = in.read(buffer);
if (i!=-1)
btList.add(buffer[0]);
wdContext.currentRequest_X_putFileDataSimpleElement().modelObject().setBtContent(btList);
wdContext.currentRequest_X_putFileDataSimpleElement().modelObject().execute();
Trying so results in:
java.lang.ClassCastException: class java.lang.Byte:null incompatible with interface com.sap.tc.cmi.model.ICMIModelClass:library:com.sap.tc.cmi(at-sign)[email protected]@alive
whenn calling the setBtContent Method
I don't what to do now to fill the context/model-object the right way.
Any helpfull hints are very welcome

Edited by: Matthias Hayk on Dec 2, 2008 10:56 AMOk Vesselin and thanx for your idea,
so i adapted the source in the way you told like the following:
ArrayList<Byte_Item> btlist = new ArrayList<Byte_Item>();
byte[] buffer = new byte[1];
InputStream in = fin.read(false);
int i = 1;
int j = 0;
while (i!=-1)
i = in.read(buffer);
if (i!=-1)
// Byte gelesen
Byte_Item bi = new Byte_Item(mAlf);
bi.setItem(buffer[0]);
btlist.add(bi);
j++;
wdContext.currentRequest_X_putFileDataSimpleElement().modelObject().setBtContent(btlist);
wdContext.currentRequest_X_putFileDataSimpleElement().modelObject().execute();
This results also in the following Exception when exceuting the WS-proxy:

Creating a method with ByRef parameter
Hi All,
when i am creating a method with parameter as ByRef, i am getting the message as fallows.
Please use valid signature.
help me to overcome frojm this.
Thanks in advance.

RajuHi,
strange... I even thought that ByRef is default parameter type for sub... maybe you can try this.
Or try to create your sub directly in the project file, maybe then you will have a proper error message from MS.

hello,
When a class has two or more methods with the same name but each method
accepts unique parameters ..... what is this called? Overloading?
Thanks,
jd
public class Test{
public Test(){
String bubby = sayHI("Jason");
System.out.println(bubby);
public String sayHI(){
return "hi";
public String sayHI(String name){
return "hi " + name;
public static void main(String[] args){
getPrefs gp = new getPrefs();is this also called overloading when your doing it with the constructor?Yes, unequivocally.
8.4.7 Overloading
If two methods of a class (whether both declared in the same class, or both inherited by a class, or one declared and one inherited) have the same name but different signatures, then the method name is said to be overloaded. This fact causes no difficulty and never of itself results in a compile-time error. There is no required relationship between the return types or between the throws clauses of two methods with the same name but different signatures.
8.8.6 Constructor Overloading
Overloading of constructors is identical in behavior to overloading of methods. The overloading is resolved at compile time by each class instance creation expression (�15.9).

How do you invoke a method with native int array argument?
Hi,
Will someone help me to show me a few codes samples on how to invoke a method which has only one argument, an int [] array.
For exampe:
public void Method1(int [] intArray) {...};
Here is some simple code fragment I used:
Class<?> aClass = Class.forName("Test2");
Class[] argTypes = new Class[] {int[].class};
Method method = aClass.getDeclaredMethod("Method_1", argTypes);
int [] intArray = new int[] {111, 222, 333};
Object [] args = new Object[1];
args[0] = Array.newInstance(int.class, intArray);
method.invoke(aClass, args);I can compile without any error, but when runs, it died in the "invoke" statement with:
Exception in thread "main" java.lang.IllegalArgumentException: object is not an instance of declaring class
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)
at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source)

at Test1.invoke_Method_1(Test1.java:262)
at Test1.start(Test1.java:33)
at Test1.main(Test1.java:12)
Any help is greatly appreciated!
JeffSorry, my bad. I was able to invoke static methods and instance methods with all data types except native int, short, double and float, not sure the proper ways to declare them.
After many frustrating hours, I posted the message for help, but at that time, my mind was so numb that I created a faulted example because I cut and pasted the static method invocation example to test the instance method passing int array argument.
As your post suggested, "args[0] = intArray;", that works. Thanks!
You know, I did tried passing the argument like that first, but because I was not declaring the type properly, I ended up messing up the actual passing as well as the instantiation step.
I will honestly slap my hand three times.

Trying to Imitate the html POST method with an applet
I am trying to imitate the POST method with an applet, so that I can eventually send sound from a microphone to a PHP script which will store it in a file on a server. I am starting out by trying to post a simple line of text by making the PHP script think that it is receiving the text within a POST-ed file. The reason I am doing things this way is in part because I am, for the time being, limited to a shared server without any support for servlets or any other server side java.
The code I am trying is based in part on an old thread found elsewhere in this forum, concerning sending data to a PHP file by imitating the POST method:
link:
http://forum.java.sun.com/thread.jspa?threadID=530399&messageID=2603608
someone named "harmmeijer" provided most of the answers on that thread. If that person is still around hope they take a look at this,also I have some questions to clarify what they said on the other thread..
My first attempt at code is below. The applet is in a signed jar file and is trying to pass a text line to the PHP script in the same directory and on the same server that the applet came from. It is doing this by sending header information that is supposed to be identical to what an html form would send if it was uploading a .txt file with the line of text within it. The applet displays one button. When you press it, it sucessfully starts up the postsim method (defined at the end), which is supposed to send the info to the PHP script at the server.
I have two questions:
1) I know that the PHP script is starting up, because it prints out a few messages depending on what happens. However, the script does not recognize any file coming down the line, so it does not save anyting on the server, and prints out a message saying the no file was uploaded.
Any idea what might be going wrong? I'm not getting any error messages from the applet. I've tried a few different variations of the 'header' information contained in the line:
osToServer.writeBytes("--****4353\r\nContent-Disposition: form-data; name=\"testfile\"; filename=\"C:testfile.txt\"\r\nContent-Type: text/plain\r\n");
The commented out line below it shows one variation (which was given in the thread mentioned above).
2) You'll notice that I've commented out the two lines having to do with the input line:
//InputStream isFromServer;
and
//isFromServer = uc.getInputStream();
The reason is that the program crahes whenever I put the latter line in - to the extent that Opera closes down the JVM and then crashes when I tried to exit it.. I must be doing something horribly wrong there! I first tried using isFromServer = new DataInputStream(uc.getInputStream());
becuase it was consistent with the output stream, but that caused the same problem.
Here's the code:
public class AudioUptest1 extends Applet{
//There are a few spurious things defined in this section, having to do with the fact the microphone data is evenuatly going to be sent. haven't yet insterted code to get input from a microphone.
AudioFormat audioFormat;
TargetDataLine targetDataLine;
SourceDataLine sourceDataLine;
DataOutputStream osToServer;
//InputStream isFromServer;
URLConnection uc;
final JButton captureBtn = new JButton("Capture");
final JPanel btnPanel = new JPanel();
public void init(){
System.out.println("Started the applet");
try
URL url = new URL( "http://www.mywebsite.com/handleapplet.php" );
uc = url.openConnection();
//Post multipart data
uc.setDoOutput(true);
uc.setDoInput(true);
uc.setUseCaches(false);
//set request headers
uc.setRequestProperty("Connection", "Keep-Alive");
uc.setRequestProperty("HTTP_REFERER", "http://applet.getcodebase");
uc.setRequestProperty("Content-Type","multipart/form-data; boundary=****4353");
osToServer = new DataOutputStream(uc.getOutputStream());
//isFromServer = uc.getInputStream();
catch(IOException e)
System.out.println ("Error etc. etc.");
return;
//Start of GUI stuff
captureBtn.setEnabled(true);
//Register listeners
captureBtn.addActionListener(
new ActionListener(){
public void actionPerformed(
ActionEvent e){
captureBtn.setEnabled(false);
//Postsim method will send simulated POST to PHP script on server.
postsim();
}//end actionPerformed
}//end ActionListener
);//end addActionListener()

I was trying to write a signed applet that helps the
user of the applet to browse the local hard disk and
select a file from the same. The JFileChooser class
from Swing is what I used in my applet. The problem
is with the policy file. I am not able to trace the
exact way to write a policy file which gives a total
access to read,write,delete,execute on all the drives
of the local hard disk.
I am successful in signing the applets and performing
operations : read,write,delete & execute on a single
file but failing to grant permission for the entire
file.
Any help would be highly appreciated.Which policy file are you using? there might be more than one policy file.
also, u have to specify the alias of the signed certificate in the policy file to grant the necessary priviledges to the signed applet. -
