error in connecting MYSQL database (Too many connections error)

[prakash shanmugam]

hai all,

 i have one major issue in my project..

 My project is developed using jsp,servlets in Tomcat5 with MySql as
database.. i am using type1 driver

 My project is now used by end users in intranet..

 When multiple users are accessing at the same time ,its throwing *too many
connections exception* at sometimes . And at sometimes its dispaying error
as "*Operation not allowed after ResultSet is closed"*

 i dont know how to rectify this ..  Can anybody help me to overcome this..

  Here is my bean file used for establing database connections...

package com.pts.database;
import java.io.*;
import java.sql.*;
import java.net.*;

public class DBCon
{
  private static final String DriverClass = "com.mysql.jdbc.Driver";
  private static final String CONNECTION_STRING = "jdbc:mysql://";
  private static final String PORT = "3306";
  private static final String DATABASE = "opts";
  private static final String user = "dav";
  private static final String pwd="";
  private static Connection  con = null;
  private static Statement stmt = null;
  private static Statement stmt2 = null;
  private static PreparedStatement pst = null;
  private static ResultSet rs = null;
  private static int count = 0;

  public static void assignCon()
  {
 String CONNECTION_IP="100.100.100.6";
try{
   Class.forName(DriverClass).newInstance();
   }
   catch(ClassNotFoundException ce){System.out.println(ce);}
   catch(InstantiationException ie){}
   catch(IllegalAccessException ie1){}

   try{
   con = DriverManager.getConnection
(CONNECTION_STRING+CONNECTION_IP+":"+PORT+"/"+DATABASE,user,pwd);
   stmt = con.createStatement();
   stmt2 = con.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE,
ResultSet.CONCUR_READ_ONLY);
   }catch(SQLException sqle){System.out.println("STMT:"+sqle);}
  }
  public static ResultSet retrieveFromDB(String sql) throws SQLException
  {
   return (stmt.executeQuery(sql));
  }
  public static ResultSet retrieveScrollDB(String sql) throws SQLException
  {
   return (stmt2.executeQuery(sql));
  }
  public static int updateDB(String sql) throws SQLException
  {
   return (stmt.executeUpdate(sql));
  }
  public static PreparedStatement prepareStmt(String sql) throws
SQLException{
 pst=con.prepareStatement(sql);
return pst;
  }
  public static ResultSet getProjectsList() throws SQLException{
 rs=((PreparedStatement)con.prepareStatement("select projID,projName from
proj_det where delFlag=0 || delFlag IS NULL")).executeQuery();
return rs;
  }
  public Connection getConn() {
return con;
  }
  public Statement getStmt()
  {
return stmt;
  }
  public  static void CloseAll() throws SQLException
  {
   stmt.close();
   stmt2.close();
   con.close();
  }
}



Hope Any of u can help me.. it would be very much helpful to me if any body
suggest me a solution to this... Because of this issue my project is in
pending..



Thanks in Advance

I think this bug is invalid.

I think you are asking for a Servlet container that uses the HTTP protocol to
communicate with the client and wish the session management mechanism to not
make use of HTTP Cookies for session tracking.

What you are asking for is not technologically feasable with any degree of
accuracy.  Since its possible to run multiple browsers per host or have multiple
hosts per IP address so cookies provide the only way to uniquely tracking each
client instance.

If you believe you have a scheme that works for you can replace/override the
inbuilt session management function with your own implementation.

Maybe you can explain how you expect session tracking to work in the provided
test case.

Hi,
I'm sorry I lost the original thread, or I'd respond there, but I
believe someone (Bill B?) asked about this earlier today: a
mod_rewrite-like Java filter, http://tuckey.org/urlrewrite/ .

   Summary: Default Tomcat configuration alows easy session
hijacking
   Product: Tomcat 5
   Version: 5.0.15
  Platform: All
OS/Version: All
Status: NEW
  Severity: major
  Priority: P2
 Component: Catalina
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: [EMAIL PROTECTED]


Tomcat should not carry over a session id generated under HTTP do HTTPS
requests. After authentication, the session ID becomes THE secret password.

In reality, many standard servlets (including e.g. Apache MyFaces servlet)
return a session ID on the first request. After switch to SSL (with
authentication), the session ID is retained, thus allowing easy session 
hijacking.

In the ideal world the session should survive the switch from HTTP to HTTPS, but
the session ID must change upon switch to HTTPS.

   Summary: Order of jar loading affects packaged resources
   Product: Tomcat 5
   Version: 5.0.28
  Platform: PC
OS/Version: Windows XP
Status: NEW
  Severity: major
  Priority: P4
 Component: Catalina
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: [EMAIL PROTECTED]


Consider two jar files:
JarA contains:
/mypackage/SomeClass.class
/mypackage/SomeClass.hbm.xml

JarB contains:
/mypackage/Another.class

When 'JarA' gets loaded before 'JarB' I have access to 'SomeClass.hbm.xml', but
when the order is changed the resource is not available. I do have access to the
classes at all time though. This behaviour only seems to occur when both jars
contain classes in the package where the resource is located.

filter to "emulate" mod_rewrite

[Jean-frederic Clere]

Hi,

Do we have a filter to "emulate" mod_rewrite features?

Cheers
