<param-value>"sun.jdbc.odbc.JdbcOdbcDriver"</param-value>I don't think you need quotes around these values.
<init-param>
<param-name>protocol</param-name>
<param-value>"jdbc:odbc:srikanth","scott","tiger"</param-value>
</init-param>I am fairly certain the value for this is incorrect. I'm assuming you're trying to use an oracle db through ODBC, based on the values above. However, I don't think the param-value element's data is correct here. Consult the oracle docs for this.
Hope this helps,
