I created a small JSP to connect to a mySQL database on another server.
Under Linux (Tomcat 5.5.4) with JDBC 3.0.16 It works fine..I get a sql result.

If I use instead of Linux windows (XP & 2000) I get the following stacktrace:
java.sql.SQLException: Unable to connect to any hosts due to exception: java.lang.NullPointerException
at com.mysql.jdbc.Connection.createNewIO(
at com.mysql.jdbc.Connection.<init>(
at com.mysql.jdbc.NonRegisteringDriver.connect(
at java.sql.DriverManager.getConnection(Unknown Source)
at java.sql.DriverManager.getConnection(Unknown Source)
at org.apache.jsp.db_002dtest_jsp._jspService(org.apache.jsp.db_002dtest_jsp:64)

All the database connections are fine (it is the same jsp)

I also tried an newer connector (3.1.5) ..without any succes.

Does someone has a clue??
