You cannot use the getParameter family of methods with multipart forms.

Are you using a 3rd-party library to process the uploaded form?

Yes, don't do it yourself. See the JspFaq for libraries that will do it for you. See https://coderanch.com/how-to/java/FileUpload

All right, I had apply the approach of using Apache Common FileUpload to retrieve the value of the textbox.
So, I did download and paste the .jar file into the Project's lib and apply the import statement.



Then I am trying the retrieve the value from the textbox.


P/S: Variable desc is declared as global variable.

And the error I got once I execute the program.


Thanks for the future advise.

You have not included all the necessary jar files. The error messages tell you what classes are missing.

Thanks for the guide.
In order to use Apache Common Fileupload approach.
Common-File.Jar & Common-Io.jar must included.
