I tried to run a sample application from "core JSP" by D.Hougland &
A.Tavistock on Tomcat3.1(all sample apps which came with tomcat work fine).
Here the code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Final//EN">
<HTML>
<BODY BGCOLOR="white">
<H1> Request Information </H1>
<H2> Request MetaData: </H2>
<BLOCKQUOTE>
<FONT SIZE=4>
Request Method: <CODE><%= request.getMethod() %></CODE>
<BR>
Query string: <CODE><%= request.getQueryString() %></CODE>
</FONT>
</BLOCKQUOTE>
<H2> Parameter Names and Values: </H2>
<BLOCKQUOTE>
<FONT SIZE=4>
<CODE>
<TABLE BORDER=0>
<%
Enumeration requestNames = request.getParameterNames();
StringBuffer outPut = new StringBuffer();
while (requestNames.hasMoreElements()) {
String Name = (String)requestNames.nextElement();
String[] Values = request.getParameterValues(Name);
for(int count = 0; count < Values.length; count++){
outPut.append("<TR>")
.append("<TD>").append(Name).append("</TD>")
.append("<TD> = </TD>")
.append("<TD>").append(Values[count]).append("</TD>")
.append("</TR>\n");
Name = " ";
}
}
out.print(outPut.toString());
%>
</TABLE>
</CODE></FONT></BLOCKQUOTE>
</BODY>
</HTML>
On some reason I keep getting the folowing error:
Error: 500
Location: /examples/jsp/parameters.jsp
Internal Servlet Error:
