Dear User, Thank you for your bug report! I have been using various connector/j versions on Red Hat 9 connection to various versions of MySQL and I haven't experienced this problem. Would it be possible for you to provide the version of mysql you are trying to connect to as well as providing the source file that is causing the problem for you? If the file is too large to attach to the bug report you can use the anonymous account on ftp.mysql.com/pub/mysql/upload and just let me know the filename. Best Regards

I have the same problem.
Running MySql server 4.0.20 and MySql Connector 3.0.18.
What is to do here?
Thanx, Ales

For some reason I am getting the same problem, my situation is I am using the connection to log the unix cpu data to a database every 15 minutes. I have a servlet which loads as soon as the the JVM starts and there is a TimeTask which is schedule to run every 15 minutes. I didn't have problem until recently i started seeing this error.

Not that it's related to the connection reset exception (which means something along the line either severed your connection, or re-started the server or machine it was running on), however if you ever have the following in a stacktrace from Connector/J, you should upgrade, as you're using an old version that doesn't have a workaround for a 'feature' in BufferedInputStreams (which many call a bug): > at java.io.BufferedInputStream.fill(BufferedInputStream.java:183) > at java.io.BufferedInputStream.read1(BufferedInputStream.java:222) > at java.io.BufferedInputStream.read(BufferedInputStream.java:277) > at com.mysql.jdbc.MysqlIO.readFully(MysqlIO.java:1391)

I have the same problem with the latest MySQL5 and the latest Connector/J : mysql-connector-java-3.2.0-alpha.
I am using this with Weblogic8.1.3 and Eclipse3.1.
The stack trace exeption is similar to those reported without the null :

The code fragment is quite similar, the comments are some try i let for the purpose because they lead to the same exception :
Class.forName("com.mysql.jdbc.Driver").newInstance();
String urlDB = "jdbc:mysql://localhost/corpo";
String userNameDB = "mgammar";
String passwordDB = "mgammar";
conn = DriverManager.getConnection(urlDB, userNameDB,passwordDB);
//conn = DriverManager.getConnection("jdbc:mysql://localhost/corpo", "mgammar", "mgammar");
//conn = DriverManager.getConnection("jdbc:mysql://localhost/corpo?user=mgammar&password=mgammar");
//conn = DriverManager.getConnection("jdbc:mysql://localhost/corpo", "root", "");
//conn = DriverManager.getConnection("jdbc:mysql://localhost/corpo?user=root");
Thank you.

Malik, Looks like your server is crashing/restarting when you try and connect...What does the .err log file that is created by the MySQL server say?

Mark, The output doesn't show any thing for today. The Eclipse console is showing the message.
