Null Pointer exception while adding header

[Varadharajan Sethuraman]

Hi,

here is my code snippet
-------------------------------------

            if (options.getHeader("Set-Cookie") == null ) { 
                options.setHeader("Set-Cookie", 
"JSESSIONID="+jsessionid);                                 
            }else { 
                options.addHeader("Set-Cookie", 
"JSESSIONID="+jsessionid);                                 
            } 
            if (options.getHeader("Set-Cookie") == null ) { 
                options.setHeader("Set-Cookie", 
"LtpaToken2="+LtpaToken2);                                 
            }else { 
                options.addHeader("Set-Cookie", 
"LtpaToken2"+LtpaToken2);                                 
            } 
            if (options.getHeader("Set-Cookie") == null ) { 
                options.setHeader("Set-Cookie", 
"LtpaToken="+LtpaToken);                                 
            }else { 
                options.addHeader("Set-Cookie", 
"LtpaToken="+LtpaToken);                                 
            } 

I am getting an null pointer exception when addHeader being called.

could you please provide me the work around for this issue?
