Hallo ...
habe noch ein Problem bei der Erstellung von Servlet in Tomcat bei der web.xml Datei...

...so hab noch mal mein Pfad eingeschrieben

+ angela2|
- database ...Datenbank
- graphics....Dateien ...Bilder und .html Dateien
+ WEB-INF
|
+ classes ...alle Java Dateien mit .class
- web.xml


unter http://127.0.0.1:8080/angela2/ aufrufen

zb: eine Showall.java Datei dazu:


import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import java.sql.*;

public class Showall extends HttpServlet
{
public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
java.util.Properties props = new java.util.Properties();
props.put("user", " ");
props.put("password", " ");
String driverName = "sun.jdbc.odbc.JdbcOdbcDriver";
String connectionURL = "jdbc😱dbc:angela2";
out.println("<html>");
out.println("<body>");
out.println("<head>");
out.println("<title>Programmierung III</title>");
out.println("<link REL='stylesheet' TYPE='text/css' HREF='../../style.css' TITLE='formal'>");
out.println("</head>");
out.println("<body bgcolor='aliceblue' topmargin='0' leftmargin='0'>");
buildtabledel(driverName,connectionURL,props,out);
out.println("</body>");
out.println("</html>");
}
void buildtabledel(String driverName,String connectionURL, java.util.Properties props, PrintWriter out)
{
out.println("<form name='frm4' method='get' action='showallresp'>");
out.println("<table border=0>");
out.println("<tr>");
out.println("<td bgcolor='yellow' height='30'><font color='blue'>&LISTING ALL RECORDS MODULE</font>&&&&&");
out.println("</td>");
out.println("</tr>");
out.println("<tr>");
out.println("<td bgcolor='WHITE'>");
listregid(driverName,connectionURL,props,out);
out.println("</td>");
out.println("</tr>");
out.println("</table>");
out.println("</form>");
}
void listregid(String driverName,String connectionURL, java.util.Properties props, PrintWriter out)
{
String query = "SELECT * FROM student_det";
boolean rc = true;
Connection con = null;
Statement stmt = null;
ResultSet rs = null;
int rowCount = 0;
out.println("<center><table border='1' bordercolor='#000000' style='border: Black;'>");
try
{
Class.forName(driverName).newInstance();
con = DriverManager.getConnection(connectionURL, props);
stmt = con.createStatement();
rs = stmt.executeQuery(query);
ResultSetMetaData rsmd = rs.getMetaData();
String tempval="";
int columnCount = rsmd.getColumnCount();
out.println("<tr bgcolor='gray'>");
for (int i = 1; i <= 3; i++)
{
out.println("<td><font color='white'>" + rsmd.getColumnLabel(i + 1) + "</font></td>");
}
out.println("</tr>");
while (rs.next())
{
out.println("<tr>");
for (int i = 1; i <= 3; i++)
{

if(i==1)
{
tempval=rs.getString(i+1);
out.println("<td><font color='black'>"+tempval+"</font></td>");
}
else
{
out.println("<td><font color='black'>"+rs.getString(i+1)+"</font></td>");
}

}
out.println("</tr>");
}
out.println("</table></center>");

}
catch (Exception ex)
{
out.println("Exception!");
ex.printStackTrace(out);
rc = false;
}
finally
{
try
{
if (rs != null)
{
rs.close();
}
if (stmt != null)
{
stmt.close();
}
if (con != null)
{
con.close();
}
}
catch (Exception ex)
{
// Do Nothing here
}
}
}
}
