Hi
According to the javadoc call commit() on autoCommit=true connection
will throw a SQLException. But a PGXAConnection
thrown a InvocationTargetException.
Because the following code, It use reflection internally.
method.invoke() will throw InvocationTargetException when underlying
method throw a Exception.
/*
* A java.sql.Connection proxy class to forbid calls to transaction
* control methods while the connection is used for an XA transaction.
*/
private class ConnectionHandler implements InvocationHandler
{
private Connection con;
public ConnectionHandler(Connection con)
{
this.con = con;
}
public Object invoke(Object proxy, Method method, Object[] args)
throws Throwable
{
if (state != STATE_IDLE)
{
String methodName = method.getName();
if (methodName.equals("commit") ||
methodName.equals("rollback") ||
methodName.equals("setSavePoint") ||
(methodName.equals("setAutoCommit") && ((Boolean)
args[0]).booleanValue()))
{
throw new PSQLException(GT.tr("Transaction control methods
setAutoCommit(true), commit, rollback and setSavePoint not allowed
while an XA transaction is active."),
PSQLState.OBJECT_NOT_IN_STATE);
}
}
return method.invoke(con, args);
}
}
