Can you write your own java classes (not servlets, just simple java
classes ) and then use the functionality of those classes in your servlet?
I wrote a class that just does some simple things such as returning an array
and tryed to use this class in my servlet. I included the class in the
classpath when I compiled the servlet, and that worked just fine, but when I
access the page I get the following error :
root cause
java.lang.NoClassDefFoundError: com/ae/rtu/RTUlist
at GreetingServlet.doGet(GreetingServlet.java:30)
BELOW IS THE CODE OF THE SERVLET :
import java.io.*;
import java.util.*;
import java.sql.*;
import javax.servlet.*;
import javax.servlet.http.*;
import com.ae.rtu.*;
public class GreetingServlet extends HttpServlet {
public void doGet (HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException
{
response.setContentType("text/html");
response.setBufferSize(8192);
PrintWriter out = response.getWriter();
// then write the data of the response
out.println("<html>" + "<head><title>RTU LIST</title></head>");
out.println("<body>");
out.println("HELLO Hello<BR>"); // Just a test print to see
if servlet is working
RTUlist r = new RTUlist();
RTU[] RTUs = r.returnTestRTUarray();
out.println("</body></html>");
out.close();
}
}
BELOW IS THE CODE OF MY SIMPLE JAVA CLASS :
package com.ae.rtu;
import java.io.*;
import java.util.*;
public class RTUlist
{
public void returnRTUarrayFromFile (File f)
{
}
public RTU[] returnTestRTUarray () // This will be a test method
{
RTU[] RTUarray = new RTU[3];
RTUarray[1].setValues("testRTU1", 1, 1, 1, 1, 2, "T1",
"MPS", 9600, "QEI", 8);
RTUarray[2].setValues("testRTU2", 1, 2, 1, 1, 2, "T2",
"Harris", 9600, "QEI", 8);
RTUarray[3].setValues("testRTU3", 1, 3, 5, 7, 9, "T3",
"MPS", 1200, "XXX", 8);
return RTUarray;
}
}
THANKS FOR ANY HELP WITH THIS !!!!
