Subject Problem using beanutils: MethodUtils.invokeMethod throw a null pointer exception
Date Thu, 01 Apr 2004 14:29:48 GMT




Hi,

I'm using MethodUtils.invokeMethod(Object myObject, String methodName,
Object[] parameters) to do some reflection in my application and I got the
following problem:

I got a null point exception when passing as parameters a table with a null
value inside like this:  [, , null, avionCargoFret, , ]
The following code inside beanutils send me the exception when it does
getClass the null element of the table:

       Class parameterTypes [] = new Class[arguments];
        for (int i = 0; i < arguments; i++) {
            parameterTypes[i] = args[i].getClass();
        }

Is this a misuse of the MethodUtils.invokeMethod?
Is this a known limitation of the implementation?
Is  this a bug?
Is there any solution out there?

Thanks by advance.

Eric
