Failed to invoke getAllServiceProviders2
java.lang.NullPointerException

[dotnetrockz]

i dont code in java but null pointer exception ante might be something like this is happening in your code......just a try frm my side

When you declare a reference variable (i.e. an object) you are really creating a pointer to an object. Consider the following code where you declare a variable of primitive type int:
int x;
x = 10;

In this example the variable x is an integer and Java will initialize it to 0 for you. When you assign it to 10 in the second line your value 10 is written into the memory location pointed to by x.
But, when you try to declare a reference type something different happens. Take the following code:
Integer num;
num = new Integer(10);
