In the same manner that ColdFusion mappings can be created at the server level and overridden by a single application with code, allow for developers to specify data sources in their Application.cfc.

This would be of great use for applications such as ContentBox Modular CMS on a shared environment as the app could install itself automatically on the user's server without needing admin access. This feature currently exists in Railo Server and looks like this:

component { = "AppName";
  // With JDBC URL (Other)

  // By datasource "type"
	  ,custom:{ characterEncoding:'UTF-8' ,useUnicode:true }

Forget *box-specific references, this just makes sense for anyone wanting to have a transportable app. CF used to have code-conifgured DSNs (until CFMX), and it makes sense to still have them. -- Adam

This issue is fixed in the next major version of ColdFusion.

Has this actually been implemented? It says it's fixed in build 288219, which should - I would have thought - been included in the CF11 public beta which is 11,0,0,288464. However I cannot get it to work. Also... I did not notice anything in the beta docs about this. Did you follow the implementation as per the Railo doc Brad linked to? It's very good news this is being done, btw. Thanks. -- Adam

Adam, this has been implemented, but not in the same manner as Railo. I just tested it last week. Basically, you can access the mappings currently defined for the application by calling the getApplicationMetadata() function and then manipulating the "mappings" struct that it returns. function addMappingCF( name, path) { var appSettings = getApplicationMetadata(); appSettings.mappings[ name ] = path; } Keep in mind, this must be done on every request, since the Application.cfc is re-created on every request. As a general note here, the same can be accomplished in CF8, 9, and 10 using an undocumented method in the application scope. I might blog this just because it is interesting. // For CF10, Add the mappings into the the application settings map // This is because getApplicationMetadata().mappings is null if none exist function addMappingCF10( name, path) { var appSettings = application.getApplicationSettingsMap(); appSettings.mappings[ name ] = path; } // CF9 is same as CF10, but with Slightly different method name function addMappingCF9( name, path) { var appSettings = application.getApplicationSettings(); appSettings.mappings[ name ] = path; }

Opps, CF8 was a typo. I never actually tried it there.
