i have created some fields like name , roll number, std. all r user editable Text input fields.
if i enter data into these fields it should be displayed in table.

and with reference to VO created table .
table is on another page as it vl be displayed once i press submit button.

}The "should be declared abstract" error message means that you have either extended an abstract class with abstract methods that you have not implemented, or you have implemented an interface and not implemented all of its methods. Non abstract classes have to implement all methods that their base classes or interfaces declare.

Class should be declared abstract
hello,
i'm learning to use the JOONE(Java Object Oriented Neural Engine).I tried to run a sample program.On compiling it gives the following error.
XorExample should be declared abstract; it does not define errorChanged(org.joone.engine.NeuralNetEvent) in XorExample
/*XorExample.java*/

import org.joone.engine.*;
import org.joone.engine.learning.*;

public class XorExample extends JFrame implements ActionListener, NeuralNetListener{I don't know anything about JOONE, but the cause of the error is the XorExample class is specified to implement the NeuralNetListener interface, and apparently it does not implement the errorChanged method of the interface.

Dear Members,
I have built a simple page in JDevloper and when tried to rebuild my project it gave me the below error:

I kindly request you to please give me some suggestions to resolve the above error.
Best Regards & Thanks,
Arun Reddy D.i have created some fields like name , roll number, std. all r user editable Text input fields.

How to declare abstract method
given - work worked at first .
fact - then i went to add new entity object names ScottOafE0 . went through all the next sand finished. a package and entity obj already exist. i also tried to put a new package and ScottOafAM in a seperate place. still a no go
when i went to run the form it errors out w/ below msg.
Error(14,8): class xxxoaf.oracle.apps.xxuab.hr.newforms.server.ScottOafEOImpl should be declared abstract; it does not define method setLastUpdateLogin(oracle.jbo.domain.Number) in class oracle.apps.fnd.framework.server.OAEntityImpl
Guess - i tired to put import oracle.apps.fnd.framework.server.OAEntityImpl in the controller file . didnt work
any idea how to define abstract method ?
thanks
scottYou dont need to define your class as abstract, that would not resolve your issue, what is happening is
oracle.apps.fnd.framework.server.OAEntityImpl is a abstract class, and has a method declared as setLastUpdateLogin(oracle.jbo.domain.Number) in class
Now, any class (xxxoaf.oracle.apps.xxuab.hr.newforms.server.ScottOafEOImpl ) extending from this class must either provide a definition to this method (provide the implementation logic), or must itself be declared abstract.
We had a discussion on this issue in the forum , look for the thread.
Thanks

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!)

I have looked this error up in three different places but the solutions do not apply to what I am trying to accomplish.
Any help would be greatly appreciated!! Thanks!

Geesh! If I had a hammer I would be hitting myself over the head with it right now!!! What an obviously DUMB newbie mistake!!!
Thanks so much for not making me feel stupid! :-)

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 workYou 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. -

Why won't people just read? The compiler prints out a perfectly comprehensible error message not only telling them what's wrong, but even how to fix it, and they just throw their hands up! "It's all too hard! Why can't someone just tell me the answer? Where's my tutor?"
Arrgh! Try working with these people: code, code, code, ooops! Red flag! Can't code any more! I don't understand!
The supposed difference between a computer and a human is that humans are supposed to get creative when faced with a difficulty, but some of 'em make you wonder.

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 greater of two int values.
int 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.
int abs(int a){return 0;}
//Returns the greater of two double values.
double max(double a, double b){return 0.0;}
//Returns the greater of two int values.
int max(int a, int b){return 0;}
// Returns the lesser of two double values.
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
// the second argument.
double pow(double a, double b){return 0.0;}
// Returns the remainder of division of two integers.
int remainder(int a, int b){return 0;}
// Returns the closest long to the argument.
long round(double a){return 0.0;}
// Returns the sum of all the elements in an array of doubles.
double sum(double [] doubleArr){return 0.0;}
// Returns the sum of all the elements in an array of ints.
int sum(int [] intArr){return 0;}
// 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};
}if you want to extend Math class to any other class.. then make all the methods abstract

Class is public, should be declared in a file?
So I'm running a program called BankAccount.java. When I tried to comile it (javac BankAccount.java) I get a message that says
BankAccount.java:4:class InsufficientFundsException is public, should be declared in a file named InsufficientFundsException.java
public class InsufficientFundsException extends Exception
^
1 error
In case you need to see it, my code is
import java.util.*;
import java.text.*;
public class InsufficientFundsException extends Exception
private int accountNumber;
private int withdrawAmount;
private int balanceAmount;
private Date date;
private DateFormat df = DateFormat.getDateInstance(DateFormat.SHORT, Locale.US);
private NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.US);
public InsufficientFundsException(int actNumb,
int amount,
int balance)
date = new Date();
accountNumber = actNumb;
withdrawAmount = amount;
balanceAmount = balance;
public String toString()
return getClass().getName() + " on " + df.format(date)
+ ". Withdraw of " + nf.format(withdrawAmount)
+ " rejected. Balance of account #" + accountNumber
+ " remains at " + nf.format(balanceAmount) ;
}Actually I did. This is how it is right now
BankAccount.java
import java.util.*;
import java.text.*;
public String toString()
return getClass().getName() + " on " + df.format(date)
+ ". Withdraw of " + nf.format(withdrawAmount)
+ " rejected. Balance of account #" + accountNumber
+ " remains at " + nf.format(balanceAmount) ;
InsufficientFundsException.java
public class InsufficientFundsException extends Exception
private int accountNumber;
private int withdrawAmount;
private int balanceAmount;
private Date date;
private DateFormat df = DateFormat.getDateInstance(DateFormat.SHORT, Locale.US);
private NumberFormat nf = NumberFormat.getCurrencyInstance(Locale.US);
public class InsufficientFundsException(int actNumb,
int amount,
int balance)
date = new Date();
accountNumber = actNumb;
withdrawAmount = amount;
balanceAmount = balance;
So do I run the bank one first? -

RekhaHi
You mean to say that the table you have queried doesnt have a column called last_update_login right ? If its the case then what you did for debugging the error. Pls share it since i was also struggling with *<<<< needs to be declared abstract; it does not define the method setLastUpdateLogin() ..>>>*
error.
Thanks.

Material statuses error message should go after entering Trackin No in PO
Hi All,
I have created one Material statuses with error message, I have created material with the use of that material statuses..
Its working fine,At the creation of PR, PO I'm getting that Error message..
My requirement is if I enter Requirement Tracking Number at item level of PR or PO means that Material statuses Error message should Go out and system has to allow to create PR or PO..
Is it possible?? how to do it?? plz help me...
Is it possible in standard SAp???
thanks and regards
rames reddyHi,
You can keep Requirement Tracking Number as Required Entry in field selection key (NBF or a copy of NBF as ZNBF) of PO document type in u201CReference data, itemu201D segment in following path:
SPRO > Materials Management > Purchasing > Purchase Order > Define Screen Layout at Document Level
And then assign field selection key to PO Document type and save.
SPRO > Materials Management > Purchasing > Purchase Order > Define Document Types
Now create PO with PO document type, system will ask you to enter Requirement Tracking Number in u201CItem Overviewu201D unless then you can save Purchase Order.
The same you can do for PR document type by having a field selection key for PR document type.
Regards,

Xmlreader schema validation error: Cannot find the declaration of element
I have multiple schemas with namespaces but I would like to validate an xml document without namespaces. The schemas all have elementFormDefault="unqualified" in the root element.
I am encountering error below in my validation using xmlreader:
ERROR:
Cannot find the declaration of element 'NewTradenetDeclaration'.
my code is:
xmlReader = XMLReaderFactory.createXMLReader("org.apache.xerces.parsers.SAXParser");
xmlReader.setFeature(VALIDATION_FEATURE_ID, true);
xmlReader.setFeature(SCHEMA_VALIDATION_FEATURE_ID, true);
xmlReader.setFeature(SCHEMA_FULL_CHECKING_FEATURE_ID, true);
xmlReader.setFeature(SCHEMA_NAMESPACE_FEATURE_ID, true);
xmlReader.setProperty(JAXP_SCHEMA_LANGUAGE, XMLConstants.W3C_XML_SCHEMA_NS_URI);
String schemaURI = "NewTradenetDeclaration.xsd";
// ive tried all of the ff but throws the same error
//xmlReader.setProperty(EXTERNAL_SCHEMA_LOCATION, "urn:crimsonlogic:tn:schema:xsd:NewTradenetDeclaration NewTradenetDeclaration.xsd");
//xmlReader.setProperty(EXTERNAL_SCHEMA_LOCATION, schemaURI);
xmlReader.setProperty(JAXP_SCHEMA_SOURCE, schemaURI);
// set entity resolver to resolve xsd locations
MyResolver resolver = new MyResolver();
xmlReader.setEntityResolver(resolver);the entity resolver has:
public InputSource resolveEntity (String publicId, String systemId) {
String filename = "c:/workspace/TXParser/schema/"+ systemId.substring(systemId.lastIndexOf("/")+1);
File f = new File(filename);
InputSource source = null;
try {
source = new InputSource(new FileReader(f));
} catch(Exception e) {
System.out.println("InputSource exception: " + e.getMessage());
return source;
}Help please. Thanks.I fight with the same error, it is curious that the schema from schemaLocation can not be validated. If i set the schema manually through an attribute it works. What i try to do is overwriting the resolveEntity in the handler to get the schema from another location and validate the xml against the schema specified in the attribute schemaLocation rather than setting it manually :-(
