JNDI doesn't work
Hi everyone;
I need help! i´m trying to set up my Tomcat 4..0.1 in such a way
than I can use a DataSource in my aplicaction called FtcApp.
My piece of server.xml regard this is:
Context path=/FtcApp docBase=FtcApp debug=0
reloadable=true
Logger className=org.apache.catalina.logger.FileLogger
prefix=localhost_FtcApp_log. suffix=.txt
timestamp=true/
Parameter name=context.param.name
value=context.param.value
override=false/
Resource name=jdbc/FtcAppDb auth=CONTAINER
type=javax.sql.DataSource/
ResourceParams name=jdbc/FtcAppDb
parameternameuser/namevaluescott/value/parameter
parameternamepassword/namevaluetiger/value/parameter
parameternamedriverClassName/name
valueoracle.jdbc.driver.OracleDriver/value/parameter
parameternamedriverName/name
valuejdbc:oracle:thin:@zagarron:1521:orcl/value/parameter
/ResourceParams
/Context
My web.xml is like this:
resource-ref
res-ref-namejdbc/FtpAppDb/res-ref-name
res-typejavax.sql.DataSource/res-type
res-authContainer/res-auth
/resource-ref
And my java code that i want it use this datasource is :
Context ctx = null;
DataSource cpds = null;
//PooledConnection pool = null;
try {
ctx = new InitialContext();
cpds = (DataSource)ctx.lookup(/jdbc/FtcAppDb);
} catch (NamingException e) {
throw new JspException(e);
}
And when i trying this i get the following error:
javax.servlet.jsp.JspException: Error:IOException mientras se insertaba
en tablajavax.servlet.jsp.JspException: El nombre jdbc no este asociado
a este contexto
