in the above code of sendmail2.jsp statements after the line which is in bold are not getting executed. please help me out. i am doing mail scheduling as my final year project and this is one of the important module

In the future, please UseCodeTags when posting code of any length. It's unnecessarily hard to read as it is, making it less likely that people will do so.

One thing that jumps out is that the code doesn't handle authentication (which Google Mail requires).

Also, it's considered bad design to do stuff like this in a JSP; use a backing bean or a servlet instead.
