marianol Posted November 8, 2012 Share Posted November 8, 2012 Do you have the correct mySQL JDBC driver installed in the ireport Classpath? Can you show which URI and class are you using when you setup the connection? Link to comment Share on other sites More sharing options...
mgeise Posted November 8, 2012 Share Posted November 8, 2012 You may want to compare the version of Java you are using in each system. Link to comment Share on other sites More sharing options...
