We have ingres database and our front end is java and jsp. Our development work is on one server and database is on different server.
When I execute following code, I don't see any exception at loading driver but I get run time exception at getConnection as follows
connection could not be established ca.edbc.util.EdbcEx: Unable to establish connection due to communications error
I got edbc.jar from ingres database,I copied edbc.jar to j2ee/home/lib directory. I don't understand what the problem is. Can somebody throw light on this please.
try {
catch (Exception ex) {
out.println("ClassNotFoundException: " +
try {
con = DriverManager.getConnection(
catch(SQLException e)
out.println("connection could not be established " + e.toString() );

You've already asked this question in the JSP forum. Rather than having a duplicate conversation, I'm going to have this thread closed and get the JSP thread moved to this forum.
I agree. Here's the link:
