    Default Help for Java method used as an Oracle function

    Hello everyone, I'm new here! (:
    I'm also quite new to Java development and Oracle either, but I'm learning.

    My problem is the following, I created a dll in .net and used it as custom function in MSSqlServer, basically this library act as a SOAP gateway letting me call a webservice (both in GET and POST) simply using a SELECT like this

    SELECT *
    FROM fn_SoapGateway_MakeWebRequest
    (
    'GET', -- Method
    'https://fish.go-moo.it', -- Url
    '/foo/bar?method=info', -- Path
    '' -- XML Envelope
    )

    Now, I want to do the same thing but using Java for Oracle.
    For testing purposes, I created the class "SoapGateway" which exposes two static methods:

    - 1) public statis String GetData() <- which returns just a string, to see that all things work good..

    - 2) public static String MakeWebRequest(String username, String password, String method, String url, String path, String envelope) <- makes the call to the webservice

    The second step is compiling everything with the Oracle java compiler so there will be no problems of java version: done!

    Now third step: binding Oracle function to the java class with a simple code like this

    CREATE OR REPLACE FUNCTION fn_SoapGateway_GetData RETURN VARCHAR2 AS
    LANGUAGE JAVA NAME 'SoapGateway.GetData() return java.lang.String';
    COMMIT;

    and last, test the simple function GetData with this select
    SELECT MY_SCHEMA.fn_SoapGateway_GetData() FROM DUAL ;
    .. works like a charme!! and it returns me my custom string.

    Now, finally I can ask you my questions:
    1) What should I write in Oracle to bind the function "MakeWebRequest" and create the function in Oracle?
    2) Is it correct sending a "String" as an Envelope and returning a "String" or should I use a bigger data type? If so, which kind of data type? Can you help me correcting my code? I can share everything once it works
    3) How can I invoke the function correctly from Oracle to obtain the response as an XML variable?

    Many many thanks for helping!
    tell me if I was not clear in something!

    Thread moved. I'm not sure that it's in the right place, but it's better than it was.
