java.lang.NoSuchMethodError

[Sona Patel]

Hi All..

I have two classes. First class has two static methods. Second class is calling one of the static methods from first class without creating instance.

Both the classes compiled without errors. But while running second class i am getting "java.lang.NoSuchMethodError" where i am calling static method of first class.

Everything seems fine. No compile time error. Then what can be the reason of this runtime error.

Thanks

We need more information:
1) The exact (copy and paste) of the error you get. Likely this will tell you exactly what the problem is
2) The lines of code that cause the error (you can get the location of the error from the stack trace the error give you.

I can not copy paste exact code but below is the snap shot of it
Classes are as below

public class abc
{
    private static String HOMECC = null;
    private static String HOMENDC = null;
    public static String getHomeCC()
	{
		return HOMECC;

	}
	
	public static String getHomeNDC()
	{
		return HOMENDC;

	}
}

public class def
{
        protected boolean isHomeSubscriber(String senderMsisdn)
        {
        	      boolean result = false;
	            String tmphomeNDC = abc.getHomeNDC(); // java.lang.NoSuchMethodError is thrown from here
                System.out.println(tmphomeNDC);
                String tmphomeCC = abc.getHomeCC(); // No Error
                System.out.println(tmphomeCC);
                return result;
        }
}

I think the java.lang.NoSuchMethodError is thrown because the interpreter is trying to find main() which you'ven't provided..

[Steve Luke]

It could be that there is no public static void main(String[] args) to be executed. Sona, instead of making us guess, could you please copy and paste the error message that you get?

Issue Resolved...
Thank you friends

It was referring to old class file somehow , which did not have newly added method. and hense "NoSuchMethodError"
So i changed the class file with new one and its working now...

thanks for your suggestions...

Did you read the API documentation first? That would have been very helpful.
