The error messages reflects that there are just compiler syntax errors:
public String getBoundary(HttpServletRequest request,Properties prop)
In this line the compiler doesn t see the SPACE between Properties and prop...
I don`t understand this, because the code you ve attached is good (there is a SPACE).
So?!
