program

Sep 3rd, 2007

I am using a example in a book to build my own program (java server pages) I can not even get the example to run. Is there someone to take a look at the program? (netbeans package)?

I have a program I am building but I had to back up to this simple program to try to understand how it should work. Please find inclosed an index.html with a links (interface.html) which should post to interface.jsp that uses file bean. I have to get a working knowledge of writing to a file and systematically go through the file and pull out correct entries. Is it easy to perform this with a simple file writer or should I be working with a random access file? Thank you for your time

That is why NetBeans should be used once you learned more about Java and development in Java. NetBeans can be realy confusing...
I found some extra bracklets in your JSP file and here is updated version

You will now able to navigate from index.html to interface.hml and interface.jsp. However once you create new bulletin and want to view it, it will not be able to display as your bean is dealilng with FileReader that is supposed to create a txt, but I di dnot have time to get it working.

If you will have some problems to run this, just post bellow
