<P>So far DAS utilized JDBC Connection - either explicitly supplied by DAS invoker or available in the runtime context pre-configured using JNDI. </P>
|
||
|
||
<P>DAS config needs to have provision to support JDBC Connection for J2SE environment, when JNDI is not configured and connection is not explicitly supplied by the DAS invoker.</P>
|
||
|
||
<P>Below are the changes in DAS Config xsd. The attribute dataSource and element ConnectionProperties<BR>
|
||
are mutually exclusive. User needs to specify ONLY one of these. When ConnectionProperties is specified, DriverManager for appropriate database vendor is used to instantiate the JDBC Connection.<BR>
|
||
This way the J2SE applications can use DAS.</P>
|
||
|
||
<P>When dataSource is specified, the JNDI context is searched for pre-configured dataSource. This mode is useful, when Web Containers like Tomcat have the resource pre-defined for the dataSource.</P>
