JSP错误“类型非法开始”

Question

I'm trying to get a JSP-File for a HTML-Form running, but I've got the following problem: When I try to run this file on a testserver (running with LiveLink), an error appears, saying:

---

500 Servlet Exception

/WebApps_e/WebApps/FORMS/Formular_Softwareantrag/PDFTest/PDFTest.jsp:34:

    try

This is how my JSP-File looks like

I've already checked for missing parentheses, but as far as I can tell, none is missing.

I don't know if it's important, but the server is running Java 1.4.2_19 (can't update it) and, as you can see, the JSP also contains iText functionalities.

Is there a mistake I made in the code itself, or can the reason for this be something different I haven't thought of?

Answer 1

This should be a servlet, not a JSP. A JSP should contain HTML code and JSP tags. Not Java code.

Regarding your question: your code is transformed to a class which looks like this:

public class TransformedJsp {
    HashMap pdfOutputs = new HashMap();
    // ...

    try {
        //...

And that's obviously invalid. A try block must be inside a method. Not directly in the class.

But I repeat: don't use a JSP for Java code. Use a servlet. That's what they're for.
