i got error multiple annotation error?what can i do??
You can provide error stacktrace.
You code can be written beautifully using JSTL/EL. Right now, it is dirty as you have used
Java code (Scriptlets), (which actually belongs to Java files), inside JSP files. Please also take a look at MVC architecture.
I know, it may be possible that you want to get it done quickly. But using Scriptlets is not the right approach for long run.
Lastly, it is Model and not modal. :)
Good luck.
