SQLException: Io exception: socket closed: Bad file number;

Question

Hi,
My server application connects oracle 8i using thin driver.
My code opens a connection and create a statement object:
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection connection = DriverManager.getConnection(url, username, password);
connection.setAutoCommit(false);
Statement statement = connection.createStatement();
After a few hours it runs just fine I get the following error:
java.sql.SQLException: Io exception: socket closed: Bad file number;
The code line that couses this exception is:
statement.executeQuery("my SQL query");
after this there are more errors:
;java.sql.SQLException: Protocol violation;
(in code line: connection.execCommit())
and than a repeated exception of :
java.sql.SQLException: Io exception: Broken pipe;
Does anyone knows a solution? (is the problem in my code or in the oracle account?)
Thank!!!

Answer 1

Which package you are using? if you don't have
classes12.zip, try again by including that package in
the classpath. If you are already using classes12.zip
then try by including nls_charset12.zip in the
classpath.
You can get these packages in Oracle (otn) website.
SudhaThanks!
I had classes12.zip in my classpath, but my classpath also had: classes111.zip
so i removed classes111.zip from the classpath and as far as now,
the problem did not occur again!
(i also added nls_charset12.zip just to be sure)
