How to run the service after getting an error

I am prasad,I am new to this webMethods.I want to handle the run time error
so I wrote a sequence.If a error gets at run time the service should not stop.It has to call one more service.Like in java how we are handling run time exceptions with try,catch and finally like that i want to handle but after getting the errors it has to call the service it should not stop.can any one
tell me how to do this.

Thanking you in advance.

I am not sure if you are familiar with Try Catch process using 3 Sequences but it does the same thing. You can find the example in WmSamples package.
