Hi!

I wrote a java-application that uses mysql-connector-java-5.1.6-
bin.jar and does well as long as Java(TM) 2 Runtime Environment,
Standard Edition (build 1.5.0_15-b04) executes the bytecode. I tried
to gain some extra-speed by compiling native.

The compiling works well again but starting the native code leads into
an error: “Unexpected exception encountered during query”. I searched
the web for a while but did not find a useful hint so I’d really
appreciate your advise where to search.

Is the connector not designed to be used for compiling native code? Or
is there a way to modify my Java-Code?

Thanks in advance

Christian

Java-Source
===========

System.out.print("Loading driver " + DATABASE_DRIVER + " ... ");

try {
    Class.forName(DATABASE_DRIVER);
}
catch (ClassNotFoundException classNotFoundException) {
    throw new
InstantiationError(classNotFoundException.getMessage());
}

System.out.println("loaded");
System.out.print("Connecting to " + server + " ... ");

try {
    String url = "jdbc:mysql://" + server + ':' + port + "/?user=" +
userName;
    if ((passWord != null) && (passWord.trim().length() > 0))
         url = url + "&password=" + passWord.trim();
    System.out.print("via " + url + " ");
    connection = DriverManager.getConnection(url);
}
catch (SQLException sqlException) {
    throw new InstantiationError(sqlException.getMessage());
}

System.out.println("connected");

Java-VM coping with the code
============================
java version "1.5.0_15"
