Hi,
The code I'm referring to is auto generated. Please note the jsp file that
fails contains *no* code at all - it's pure html. The line referenced is
the end of the file. There must be a configuration error in system
somewhere. Is there a knowledge base that would indicate the problem?
Line 66 is marked below:
>From this I presume one of pageContext, or _jspxFactory is knackered. But
why- this is autogenerated code. What could be wrong with the tomcat config
to cause this problem. Also please note, this is an autoinstall of Sun's
Cobalt JDK on a Cobalt RaQ4.
package jsp;
import javax.servlet.*;
import javax.servlet.http.*;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
import java.io.PrintWriter;
import java.io.IOException;
import java.io.FileInputStream;
import java.io.ObjectInputStream;
import java.util.Vector;
import org.apache.jasper.runtime.*;
import java.beans.*;
import org.apache.jasper.JasperException;
public class _0002fjsp_0002ftest_0002ejsptest_jsp_1 extends HttpJspBase {
static {
}
public _0002fjsp_0002ftest_0002ejsptest_jsp_1( ) {
}
private static boolean _jspx_inited = false;
public final void _jspx_init() throws JasperException {
}
public void _jspService(HttpServletRequest request, HttpServletResponse
response)
throws IOException, ServletException {
JspFactory _jspxFactory = null;
PageContext pageContext = null;
HttpSession session = null;
ServletContext application = null;
ServletConfig config = null;
JspWriter out = null;
Object page = this;
String _value = null;
try {
if (_jspx_inited == false) {
_jspx_init();
_jspx_inited = true;
}
_jspxFactory = JspFactory.getDefaultFactory();
response.setContentType("text/html;charset=8859_1");
pageContext = _jspxFactory.getPageContext(this, request,
response,"", true, 8192, true);
application = pageContext.getServletContext();
config = pageContext.getServletConfig();
session = pageContext.getSession();
out = pageContext.getOut();
// HTML // begin
[file="/usr/java/jakarta-tomcat-3.2.1/webapps/examples/jsp/test.jsp";from=(0
,0);to=(5,0)]
out.write("<html>\r\n<body>\r\n</body>\r\n</html>\r\n\r\n");
// end
} catch (Exception ex) {
if (out.getBufferSize() != 0)
out.clearBuffer();
pageContext.handlePageException(ex);
} finally {
>>> out.flush();
_jspxFactory.releasePageContext(pageContext);
}
}
}
Thanks
Martin

Subject: Re: [cobalt-developers] NullPointerException running JSP samples in
Cobalt RaQ4 tomcat in
Martin,
Your problem is right in front of you, you have a null pointer
on line
66. Go and look at your code, becuase there is something that is
supposed to have/return a value but instead is returning a null pointer.
Check out your code again.
Good luck.
