Hey,
I developed an application for red5 which connects to a Mysql database and
SELECTs a set of data. On my Windows PC everything works fine.
I installed the mysql-connector-java-5.0.7-bin.jar. I made a directory
called "lib" in the WEB-INF folder of my project and copied the
mysql-connector-java-5.0.7-bin.jar to this location.
When I try to use the application on Linux it crashes with the following
error message:
(streamName is a function of the application.java.)
[ERROR] 498512 pool-3-thread-2:(
org.red5.server.service.ServiceInvoker.invoke ) Error executing call:

I think java cannot find the mysql connector?
Or do I connect in a wrong way?
Some excerpts of my application.java ( I am not so advanced in programming
with java ;) ).
import java.sql.*;
[...]
java.sql.Connection conn = null;
try {
Class.forName("com.mysql.jdbc.Driver").newInstance();
}
[...]
public static String streamName(String sid) {
rs = stmt.executeQuery("SELECT `stream_name` FROM `eingeloggte_user`
WHERE `sid`='"+sid+"'");
while ( rs.next() ){
StreamName = rs.getString(1);
}
rs.close();
stmt.close();
con.close();
}
[...]
conn = java.sql.DriverManager.getConnection(
"jdbc:mysql://localhost/test?user=m_giesel&password=...");
[...]
Thanks!
Max
