I have developed a web application that uploads the file from client machine to server. it works well with Firefox and Apple Safari browser but when i try it with Internet Explorer,it sends onl开发者_StackOverflow社区y the boundary.I have set EncType as multipart/form-data.i am using servlet to receive the file. But file sent by IE does not received at servlet only boundary is received. How can I solve this?

You should not homegrow a multipart/form-data parser. Rather pick a robust, thoroughly developed and well maintained library like Apache Commons FileUpload. You can find a kickoff example in this answer.
