This implementation is not specific to any particular type of the resource adapter or connection factory interface. <p>The ConnectionManager implementation delegates to the application server to enable latter to provide quality of services (QoS) - security, connection pool management, transaction management and error logging/tracing. <p>An application server implements these services in a generic manner, independent of any resource adapter and EIS specific mechanisms. The connector architecture does not specify how an application server implements these services; the implementation is specific to an application server. <p>After an application server hooks-in its services, the connection request gets delegated to a ManagedConnectionFactory instance either for the creation of a new physical connection or for the matching of an already existing physical connection. <p>An implementation class for ConnectionManager interface is required to implement the <code>java.io.Serializable</code> interface. <p>In the non-managed application scenario, the ConnectionManager implementation class can be provided either by a resource adapter (as a default ConnectionManager implementation) or by application developers. In both cases, QOS can be provided as components by third party vendors.</p><P><P><DL><DT><B>Since:</B></DT> <DD>0.6</DD><DT><B>Author:</B></DT> <DD>Rahul Sharma</DD><DT><B>See Also:</B><DD><A HREF="../../../javax/resource/spi/ManagedConnectionFactory.html" title="interface in javax.resource.spi"><CODE>ManagedConnectionFactory</CODE></A></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/Object.html" title="class or interface in java.lang">Object</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../javax/resource/spi/ConnectionManager.html#allocateConnection(javax.resource.spi.ManagedConnectionFactory, javax.resource.spi.ConnectionRequestInfo)">allocateConnection</A></B>(<A HREF="../../../javax/resource/spi/ManagedConnectionFactory.html" title="interface in javax.resource.spi">ManagedConnectionFactory</A> mcf, <A HREF="../../../javax/resource/spi/ConnectionRequestInfo.html" title="interface in javax.resource.spi">ConnectionRequestInfo</A> cxRequestInfo)</CODE><BR> The method allocateConnection gets called by the resource adapter's connection factory instance. </TD></TR></TABLE> <P><!-- ============ FIELD DETAIL =========== --><!-- ========= CONSTRUCTOR DETAIL ======== --><!-- ============ METHOD DETAIL ========== --><A NAME="method_detail"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=1><FONT SIZE="+2"><B>Method Detail</B></FONT></TD></TR></TABLE><A NAME="allocateConnection(javax.resource.spi.ManagedConnectionFactory, javax.resource.spi.ConnectionRequestInfo)"><!-- --></A><H3>allocateConnection</H3><PRE>public <A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/Object.html" title="class or interface in java.lang">Object</A> <B>allocateConnection</B>(<A HREF="../../../javax/resource/spi/ManagedConnectionFactory.html" title="interface in javax.resource.spi">ManagedConnectionFactory</A> mcf, <A HREF="../../../javax/resource/spi/ConnectionRequestInfo.html" title="interface in javax.resource.spi">ConnectionRequestInfo</A> cxRequestInfo) throws <A HREF="../../../javax/resource/ResourceException.html" title="class in javax.resource">ResourceException</A></PRE><DL><DD><p>The method allocateConnection gets called by the resource adapter's connection factory instance.
