java.lang.Exception;

[arijeet]

Hi,
I am facing the following error while compiling my code:
unreported exception java.lang.Excep tion; must be caught.....(err or is at line 100
function = this.createFunc tion("ZTEST", mRepository);)


The code is :

}[/code]

Why is this happening??Appr eciate some help

You defined your createFunction to throw an Exception. When you call it
you don't try .. catch that possible Exception; that's what your compiler is
complaining about: you either have to define your calling function to throw an
Exception as well or you have to catch the Exception thrown by the createFunction.

kind regards,

Jos

ps. I added code tags around your code for readability reasons.

Hi Jos,

I have made the following changes in the code:

// imports to include the required libraries.
//Start of imports.

import com.sap.mw.jco.*;
import com.sap.spe.pricing.*;
import java.math.BigDecimal;
import com.sap.spe.base.logging.UserexitLogger;

import com.sap.spe.pricing.transactiondata.userexit.IPricingConditionUserExit;
import com.sap.spe.pricing.transactiondata.userexit.IPricingDocumentUserExit;
import com.sap.spe.pricing.transactiondata.userexit.IPricingItemUserExit;
import com.sap.spe.pricing.transactiondata.userexit.ValueFormulaAdapter;

//End of imports.

public class zconprc1 extends ValueFormulaAdapter
{
	public BigDecimal overwriteConditionValue(IPricingItemUserExit item,
				IPricingConditionUserExit condition) {
		
		BigDecimal item_guid;
		String guid;
		JCO.Structure finalStructure;

		guid = item.getProduct().getId(); //Returns GUID
		
		
		item_guid = new BigDecimal(guid);
		finalStructure = passPar(item_guid); //Call to the remote function.

		return item_guid;
	}



	public JCO.Function createFunction(String name,JCO.Repository mRepository) extends Exception
	{

			try
			{
				IFunctionTemplate ft = mRepository.getFunctionTemplate(name.toUpperCase());					
										
			}
			catch (Exception ex){
				throw new Exception("Problem retrieving JCO.Function object.");
			}
			
			if (ft == null)
				return null;
			return ft.getFunction();
	}


	


	public JCO.Structure passPar(BigDecimal item_guid) 
	{
			JCO.Client mConnection;
			
		
			// Create a client connection to a dedicated R/3 system
			 mConnection =   JCO.createClient("100",      // SAP client
                		      	       	       "crm_jco",         // remote userid
                        		       	       "SAREGAMA",         // password
                               			       "EN",       // language
                               	       		       "192.168.39.209", // host name
                               	       	       	       "01",     // system number 
	                         	 	       "192.168.39.209", //Gateway Host
					               "sapgw01" );      //Gateway Service Name

			//Establishing the connection
			try
			{
				System.out.println("Starting Session....");
				System.out.println("\n");
				System.out.println("\n");

				mConnection.connect();
				//System.out.println(mConnection.getAttributes());
				// Not required

			JCO.Repository mRepository;
			JCO.Function function;
			
			//Creating a JCO repository
			mRepository = new JCO.Repository("TEST", mConnection);

			//Executing a Function
			function = this.createFunction("ZTEST", mRepository);
			
			//Import Scalar Import Parameter (item_guid)
			function.getImportParameterList().setValue("int","item_guid");
			
			mConnection.execute(function);

			JCO.Structure returnStructure = function.getExportParameterList().getStructure("RETURN");
		
			//return returnStructure;
						
										
			}
			
			catch (Exception e){
				e.printStackTrace();
				System.exit(1);
			}

			return returnStructure;		


	}


}

It now gives the error :
zconprc1.java:3 7: ';' expected
public JCO.Function createFunction( .....) extends Exception

I have included the function call within the try block. Why this error??

A method can't "extend" anything; only classes can extend other classes.

@arijeet : you didn't read Jos's reply carefully. he never said that you have to modify the 'createFunction' function. This is what Jos suggested :
1. define your calling function to throw an Exception as well -> which means that 'passPar'(this is the calling function) should also throw an exception. See the implementation of 'createFunction' function in your code(the one before you modified it) to see how a method is declared to throw an exception.
2.catch the Exception thrown by the 'createFunction' -> this means that the call to 'createFunction' (which is in line 100 of the unmodified code of yours) should be surrounded by a try/catch block. There is already a try/catch block in 'passPar'. Look at it to see how it is used.

@Jos : After the mistake that arijeet made after your reply, i felt he would need a little more explanation.

Sure, I hope s/he gets it now; randomly juggling with keywords and hoping it
means what one hopes it means is an endless mess. IMHO the OP should read
a tutorial first.
