Compiler error: Missing JSP library?

Question

Hi All,
I am really new at this, and I know that I'm making some sort of simple mistake.
I have an existing application running on a 9i middle tier. I want to make a couple of simple changes to a .JSP. So I downloaded the EAR file, loaded it into JDeveloper (10.1.3.0.4 SU4), made my changes and tried to run it locally. I got 241 compiler errors. So I reverted to the original EAR, and I still get 241 compiler errors.
The errors are:
Error(1,5): illegal forward reference
Error(1,14): duplicate definition of class _index
Error(1,48): HttpJsp not found in class _index
Error(1,62): method getPageContext(_index, javax.servlet.http.HttpServletRequest, javax.servlet.http.HttpServletResponse, null, boolean, int, boolean) not found in class javax.servlet.jsp.JspFactory
The code is:
<sample>
import oracle.jsp.runtime.*;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.jsp.*;
public class _index extends oracle.jsp.runtime.HttpJsp {
public final String _globalsClassName = null;
public void _jspService(HttpServletRequest request, HttpServletResponse response) throws java.io.IOException, ServletException {
response.setContentType( "text/html;charset=windows-1252");
/* set up the intrinsic variables using the pageContext goober:
** session = HttpSession
** application = ServletContext
** out = JspWriter
** page = this
** config = ServletConfig
** all session/app beans declared in globals.jsa
PageContext pageContext = JspFactory.getDefaultFactory().getPageContext( this, request, response, null, true, JspWriter.DEFAULT_BUFFER, true);
// Note: this is not emitted if the session directive == false
HttpSession session = pageContext.getSession();
if (pageContext.getAttribute(OracleJspRuntime.JSP_REQUEST_REDIRECTED, PageContext.REQUEST_SCOPE) != null) {
pageContext.setAttribute(OracleJspRuntime.JSP_PAGE_DONTNOTIFY, "true", PageContext.PAGE_SCOPE);
JspFactory.getDefaultFactory().releasePageContext(pageContext);
return;
</sample>
So, I read the forums, etc and decided that I need ojsp.jar included in my project libraries. So I went to libraries under project properties, and I already have "Jsp Runtime" as my first library and it claims to include ojsp.jar. I've tried removing and re-adding the library, adding other libraries ("J2EE","Servlet Runtime","OC4J Deployment Plugin"...), and a dozen other things, none of which have allowed my to compile.
Any ideas on what I should do?

Answer 1

you might need to post more code, but basically the
compiler is complaining because you do not have a
return statement at the end of your method.
if you do not have a return statement (with a matching
return type) then the compiler will complain. If you
don't understand this then post the code to your
method and we can get it fixed.
public String[] read(InputStream list) throws
Exception {
String[] stringArray;
return stringArray;
The code is the most complex I have written so far but here is some of it. (the begining and the end)
public String[] read(InputStream list) throws Exception {
if (list != null) {
String[] stringArray = null;
try {
while {
//add strings to string array
}//end of while
return stringArray;
}// end try
catch{
}//end of method
