Try to work Checked Exceptions in doInTransactionWithoutResult

[dr_pompeii]

Hello

I have this code

public void purchase(final String isbn, final String username)throws Exception  {
        
     RuleBasedTransactionAttribute attr = new RuleBasedTransactionAttribute();
     attr.getRollbackRules().add(new RollbackRuleAttribute(IOException.class));
     attr.getRollbackRules().add(new NoRollbackRuleAttribute(ArithmeticException.class));
				    		    
    TransactionTemplate transactionTemplate =
            new TransactionTemplate(transactionManager,attr);
       			
		
	transactionTemplate.execute(new TransactionCallbackWithoutResult() {

            protected void doInTransactionWithoutResult(
                    TransactionStatus status) {
	                    
                     ....some logic with persistence
		    throw new ArithmeticException();
		    //throw new IOException();		    
   	    }
        });
    }

If I dont comment throw new ArithmeticException(); (and yes IOException of course), I dont recieve any compile errors (because is a unchecked exception), the rollback rule works fine.

to rollback

	attr.getRollbackRules().add(new RollbackRuleAttribute(ArithmeticException.class));

or dont rollback

	attr.getRollbackRules().add(new NoRollbackRuleAttribute(ArithmeticException.class));

but If I dont comment throw new IOException(); like

                     ....some logic with persistence
		    //throw new ArithmeticException();
		    throw new IOException();

I recieve instead

[javac] .......java:128: unreported exception java.io.IOException;
must be caught or declared to be thrown
[javac] throw new IOException();
[javac] ^
[javac] 1 error

How I can handle this?

or is mandatory only to work with unchecked exceptions?
I dont want handle any exception inside doInTransactionWithoutResult method

Thanks in advanced
