shot from the hip:
- specify all databases available inside your context.xml-file
- from the url, read a parameter (such as "&customer=scrooge")
- depending on the parameter, create the datasource:
try {
Context env = (Context) new
InitialContext().lookup("java:comp/env");
dbDS = (DataSource) env.lookup(customer);
if (dbDS == null) {
logger.error("seems that '" +
dataSourceName + "' is an unknown
DataSource");
throw new ServletException("'" +
dataSourceName + "' is an
unknown DataSource");
}
} catch (NamingException e) {
logger.error("Exception caught:", e);
throw new ServletException(e);
}
