convert from string to inputstream

[usha mocherla]

Hi
I am new user of java.
Can anybody help me in changing from string to InputStream.
This is following code:
String inputstream=request.getParameter("inputstream");
InputStream in=request.getParameter("inputstream");
It gives error "cannot convert from string to InputStream"
Plz help me.
Regards

Assuming that request is an instance of HttpServletRequest, the method getParameter() returns a String, in the line

InputStream in=request.getParameter("inputstream");

you are trying to cast the String into an InputStream. If you want an InputStream from request, you have to call the getInputStream() method inherited from ServletRequest.
