Hello Berin,
I went a little further and got more of an education of the workings of
avalon and cocoon (the greatness of open source :)). Got the latest cvs of
avalon and cocoon2 compiling and working with mysql databases using
tomcat-4.0.2-b1 and jdk1.4-beta3!
In the JdbcConnectionPool I changed JdbcConnection to AbstractJdbcConnection
and in JdbcConnectionFactory changed JdbcConnection to Jdbc3Connection and
the constructors were gotten. This of course won't work with jdk1.3.x.
Starting at line 105 in JdbcConnectionFactory:
if ( null != this.m_connectionClass )
{
try
{
Class clazz =
Thread.currentThread().getContextClassLoader().loadClass(
this.m_connectionClass );
Class[] paramTypes = new Class[] { Connection.class,
String.class };
Object[] params = new Object[] { connection,
this.m_keepAlive };
Constructor constructor = clazz.getConstructor(
paramTypes );
System.out.println(this.m_connectionClass);
jdbcConnection = (Jdbc3Connection)
constructor.newInstance( params );
System.out.println("first try");
}
catch ( Exception e )
{
...
"first try" ouput occurs when run.
Question: Do you want to make Jdbc3Connection a subclass of JdbcConnection
or use the AbtractJdbcConnection throughout the code?
Regards,
Roger
