Import a Java Library into CouchDB JavaScript Validation Function
I would like to use a java library within a validation function for accessing
an external properties file. Something like the following:
importPackage(Packages.java.io);
importPackage(Packages.java.util);
var file = new File(sPropertyFile);
var fis = new FileInputStream(file);
var prop = new Properties();
prop.load(fis);
var field = prop.getProperty("FIELD1");
Can anyone tell me if CouchDB allows the importing of Java Library
(Packages) and if so can you provide me instructions or an example of how to
go about doing this?
Much appreciated.
Kyle

You might find a Java view server around, though evaluating Java
snippets is a bit of a black art, but no sane view server will permit
reading local files.

AFAIK, this is not possible as validate_doc_update functions can only be
written in javascript. (Maybe also Erlang? But I don't think so)
You might want to use something like JSON schema for consistent client and
server validation, as you can import more javascript with CommonJS modules.
