Subject Re: [Firebird-Java] Re: connect would work better
Author Mark Rotteveel
I am unable to reproduce your problem. I used the following code in a
project that includes the Jaybird-2.1.6-full.jar:

import java.sql.Connection;
import java.sql.SQLException;
import javax.sql.PooledConnection;
import org.firebirdsql.pool.FBConnectionPoolDataSource;

public class JeanProblem {

public static void main(String[] args) throws SQLException {
FBConnectionPoolDataSource dataSource = new
FBConnectionPoolDataSource();
dataSource.setMaxStatements(10);
dataSource.setMaxIdleTime(30 * 60 * 60);
dataSource.setPooling(true);
dataSource.setMaxPoolSize(5);
dataSource.setMinPoolSize(2);
dataSource.setLoginTimeout(10000);
dataSource.setDatabase("localhost:D:/data/db/TESTDB.FDB");
dataSource.setPassword("masterkey");
dataSource.setUserName("SYSDBA");
PooledConnection pooledConnection =
dataSource.getPooledConnection();
Connection connect = pooledConnection.getConnection();
}
}

All I have done to get this to work in NetBeans (6.9) is:
1) Add the Jaybird library to NetBeans:
- Tools, Libraries, Add new library
- Library Name: Jaybird-2.1.6
- Library Type: Class Libraries
- Ok
- On Tab Classpath, Add JAR/Folder
- Browse to the Jaybird-2.1.6-full.jar and select it
- Add JAR/Folder
- Ok
2) Create a new project
- File, New Project
- Select Java, Java Application
- Next
- Fill in names for the project, location and main class
- Finish
3) Add Jaybird library to the project
- In the Projects view, right-click on the 'Libraries' folder for the
new project
- Add Library
- Select 'Jaybird-2.1.6' library from the list
4) Enter code
5) Run: it works, no errors (except in the Firebird log as I don't close
the connection pool before the program ends ;)

BTW: For normal applications you would normally use the
FBWrappingDataSource if you want connection pooling. You should not use
the FBConnectionPoolDataSource; FBConnectionPoolDataSource (and its
getPooledConnection()-method) are intended for managed environments like
JEE servers.

>>> Then you really are doing something wrong in Netbeans. I think you simply forgot to add the library to your project. Step 1 is creating a user library for Jaybird in Netbeans (which I think you did), step 2 is adding that library to your current project (which I you forgot to do). After that imports should just work. There is never a good reason to need to include the source of a dependency into your own program.
