Java EE (Java Enterprise Edition) General Discussion

I'm working on windows 2000 server with Tomcat4.0, and j2sdk1.4.0.

servlet.jar and cos.jar are both located on d:\Tomcat4.0\common\lib and system's classpath.

The code passed the compile, but got error on run time. I check the post here, but didn't found the resolution. Would anyone be able to help me? Thanks indeed!

Code is:

import java.io.*;
import java.sql.*;
import java.util.*;
import java.text.*;
import java.math.*;

import javax.servlet.*;
import javax.servlet.http.*;

import com.oreilly.servlet.*;

public class TemperDocServlet extends TemperBaseServlet
{
private Connection conTemper=null;
private Statement stTemper=null;
private StringBuffer sbTemperDoc = new StringBuffer();
private String pageTitle="";
private PrintWriter lout=null;

private SimpleDateFormat formatter=new SimpleDateFormat("MM/dd/yyyy");

protected void doGet (HttpServletRequest gareq, HttpServletResponse gares) throws ServletException, IOException
{
lout=gares.getWriter();
gares.setContentType(" text/html");

try {
Class.forName(getJDBCClass());
conTemper = DriverManager.getConnection(getDBURL(), getDBUser(), getDBPassword());
createMain(gareq);
if (stTemper!=null) stTemper.close();
if (conTemper!=null) conTemper.close();
} catch(Exception aException) { errorHandler(gares, lout, aException,aException.getMessage()); }
}

protected void doPost (HttpServletRequest pareq, HttpServletResponse pares) throws ServletException, IOException
{
lout=pares.getWriter();
pares.setContentType(" text/html");

try {
Class.forName(getJDBCClass());
conTemper = DriverManager.getConnection(getDBURL(), getDBUser(), getDBPassword());
createMain(pareq);
if (stTemper!=null) stTemper.close();
if (conTemper!=null) conTemper.close();
} catch(Exception aException) { errorHandler(pares, lout, aException,aException.getMessage()); }
}

private void createMain(HttpServletRequest areq) {
try {
String lLocalSaveDirectory = "D:\\InetPub\\wwwroot\\temper\\doc";
MultipartRequest lMultipartRequest = new MultipartRequest(areq, lLocalSaveDirectory, 10*1024*1024); // 10MB
if(lMultipartRequest.getParameter("submit").equals("Upload"))
{
sbTemperDoc.append("Files:");
Enumeration lFile = lMultipartRequest.getFileNames();
while (lFile.hasMoreElements()) {
String name = (String)lFile.nextElement();
String filename = lMultipartRequest.getFilesystemName(name);
String type = lMultipartRequest.getContentType(name);
File f = lMultipartRequest.getFile(name);
FileReader fs = new FileReader(f);
BufferedReader in = new BufferedReader(fs);
String s, s2 = new String();
while((s = in.readLine())!= null) s2 += s + "\n";
//fileContent = s2;
//session.setAttribute("fileContent", fileContent);
//out.println(in.readLine());
sbTemperDoc.append("name: " + name);
sbTemperDoc.append("filename: " + filename);
sbTemperDoc.append("type: " + type);
if (f != null) {
sbTemperDoc.append("f.toString(): " + f.toString());
sbTemperDoc.append("f.getName(): " + f.getName());
sbTemperDoc.append("f.exists(): " + f.exists());
sbTemperDoc.append("f.length(): " + f.length());
sbTemperDoc.append("fileContent: " + s2);
}
in.close();
}
}
} catch (IOException e) { System.out.println("Error::"+e); }

writeBody(lout, pageTitle, sbTemperDoc.toString(), writeLinkButton(""));
sbTemperDoc.setLength(0);
}
}

the error is:

exception
