Problem with using getColumns() with informix database

Hi, I have connected to a informix database and I am trying to get the columns names by using the JDBC DatabaseMetaData and the function getColumns(). try { Class driver = Class.forName("informix.api.jdbc.JDBCDriver"); DriverManager.registerDriver((Driver)driver.newInstance() ); Connection connection = DriverManager.getConnection("jdbc:informix-api-direct:" + ";system=informix"+ ";database=jsadb, username, password); Statement statement = connection.createStatement(); DatabaseMetaData dbmd = connection.getMetaData(); // // it gives an error on the line below // ResultSet col = dbmd.getColumns(null,null,"%",null); ResultSetMetaData rsm = col.getMetaData(); } The error that it produces is:- "infotmix.api.jdbc.JDBCException: XIX000:-674:Routine (_i japi jdbc_cvtype) cannot be resolved" Has anybody got an idea on what I am doing wrong. Any help will be much appreciated. Thanks, Jas
