Hi Nicholas,
I thank you for your response. Here is a servlet that I have been trying to run, as
you can see it is from the course material of an university and if you run it at their
site it works. I have made some modifications like, instead of handling the doPost()
by calling doGet() from the method, I have called it directly. Also I have tried out
the various suggestions that I found in the archives.
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.*;
/** Shows all the parameters sent to the servlet via either
* GET or POST. Specially marks parameters that have no values or
* multiple values.
* <P>

public class ShowParameters extends HttpServlet {
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
String type= request.getContentType();
System.out.println(request.getContentLength());
System.out.println(type);
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String title = "Reading All Request Parameters";
StringBuffer sb = new StringBuffer();
sb.append(ServletUtilities.headWithTitle(title) +
"<BODY BGCOLOR=\"#FDF5E6\">\n" +
"<H1 ALIGN=CENTER>" + title + "</H1>\n" +
"<TABLE BORDER=1 ALIGN=CENTER>\n" +
"<TR BGCOLOR=\"#FFAD00\">\n" +
"<TH>Parameter Name<TH>Parameter Value(s)");
Enumeration paramNames = request.getParameterNames();
while(paramNames.hasMoreElements()) {
String paramName = (String)paramNames.nextElement();
sb.append("<TR><TD>" + paramName + "\n<TD>");
String[] paramValues = request.getParameterValues(paramName);
if (paramValues.length == 1) {
String paramValue = paramValues[0];
if (paramValue.length() == 0)
sb.append("<I>No Value</I>");
else
sb.append(paramValue);
} else {
sb.append("<UL>");
for(int i=0; i<paramValues.length; i++) {
sb.append("<LI>" + paramValues[i]);
}
sb.append("</UL>");
}
}
try{
sb.append("</TABLE>\n</BODY></HTML>");
response.setContentLength(559);
System.out.println("Buffer length" + sb.length());
out.print(sb.toString());
out.close();
}catch(Throwable e){System.out.println("Inside socket exception");}
}
}

It would be helpful if you could post some code, since
I am not sure that any data you have provided is
sufficent to diagnose the problem.
