I configured Jakarta-Tomcat-4.1.27 to supply connections of my Oracle Database Server through JNDI Datasource as described in http://jakarta.apache.org/tomcat/tomcat-4.1-doc/jndi-datasource-examples-howto.html
All accomplished the tests of JNDI Datasource HOW-TO and everything perfectly worked. Later, reading a magazine of ORACLE finds an article on Six JDBC Tips goes Enterprise Web Application (Setember/October 2002), more specifically with an example on Datasources according to code below: ... Context ctx = new InitialContext(); DataSource ds = (DataSource) ctx.lookup("java:comp/env/jdbc/pequi"); conn = ds.getConnection("CELIN","1951174"); conn.setTransactionIsolation(Connection.TRANSACTION_SERIALIZABLE); ... My question is if I can pass the user and connection password to the servant of database in the way that is being done above, because in all of the examples of JNDI Datasource HOW-TO user's name and the password are so much defined in server.xml, together with the configuration. When executing the code I am receiving the error message java.lang.UnsupportedOperationException at datasource.OracleDataSource.conecta_datasource(OracleDataSource.java:18) The line 18 of the code is exactly the same in that step the user and the respective password.
