java - JDBC connection does not run with .jar file, but with eclipse project -

i'm looking @ mystery here. created java program in eclipse , established jdbc connection. code following:

import java.sql.*;  public class login {      public static void main(string[] args) {         try {             // class.forname("com.microsoft.sqlserver.jdbc.sqlserverdriver");             connection connection = drivermanager                     .getconnection("jdbc:sqlserver://localhost;databasename=testdb; integratedsecurity=true;");                                    //adding port 1433 doesn't make difference               system.out.println("connection successful");             statement st = connection.createstatement();             resultset rs = st.executequery("select * testtable");              while (rs.next()) {                 line = rs.getstring(2);             }          } catch (exception e) {             e.printstacktrace();         }     } } 

when i'm running within eclipse, everything's fine. database , tables good, library , authentication in java built path set , result want, namely "hello world", string in selected table.

but creating executable jar file , running throws exception "this driver not configured integrated authentication". not connect, if there error in database wouldn't matter @ point.

even more confusing fact, weeks earlier, created executable jar file , worked!

os: windows vista home premium x86 (i know, win7 lappy broken)

jdbc driver location: "c:\sqljdbc_4.0\enu\sqljdbc4.jar"

native library location: "c:\sqljdbc_4.0\enu\auth\x86"

java version: java 7 update 17 , jdk 7 update 17

previousely, used update 21, changed check if driver reason.

so, suggestions? i'd grateful!

btw, hope sscce, because don't know how smaller , more correct make it...

• check runtime classpath of eclipse, try create system level "classpath" variable , add same path. once variable set, execute in new command prompt or reload environment variables

• make sure executable jar has dependency in manifest.mf necessary jars (along mainclass)

• finally, practice in java make first alphabet in capital ("login" instead of "login")
