[protege-dev] Exception when executing custom built-in with Jess

[Martin O'Connor]

That is not at the beginning of the method. There are several commands before it that could throw exceptions.

Can you just replace the entire method body with a log command and see if there is still an exception?

e.g.,


public boolean mymethod(List<SWRLBuiltInArgument> arguments) throws SWRLBuiltInException
 {
   System.out.println("my method");
 }

Hello
I put the instruction System.out.println at the beginning of my method
.
.
checkNumberOfArgumentsEqualTo(numberOfArguments, arguments.size());
       String s1 = getArgumentAsAString(argument1Number, arguments);
       String s2 = getArgumentAsAString(argument2Number, arguments);
       System.out.println("opening line of the function");

but it does not display in the log file of protege,
