This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
Let me begin by saying I am VERY new to servlets. I only just got my system setup to develop locally. I am able now to run everything (including Tomcat 7) inside eclipse. I have made my first servlet and jsp. I have a button in my JSP that will one day post a string, "HelloWorld" to a servlet. Until then, I am just making a String out of Hello \n World, then I send it to my JSP. It is here I run into a problem. I don't want to cast my 2d array as a String object type in the JSP.
My Question: How do I preserve the object type in the transition from servlet to jsp?
Although I don't think it will help, I will provide my code.
EDIT: I have edited this code so it is at least working.
I recommend you do not use server-side script (the stuff inside the <% ... %>) in your JSPs. Your servlet is passing a object to the JSP, so use tag libraries and the expression language to extract the information out of the object. In your example, the twoDStrArr object is a little complex for me to come up with a decent example off the top of my head, so let me change your example to something very simple to show what I mean.
