Subject [jira] [Commented] (XMLRPC-195) StringSerializer does not create <string> tag
Date Tue, 20 Nov 2012 11:30:58 GMT

    [ https://issues.apache.org/jira/browse/XMLRPC-195?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13501116#comment-13501116
] 

Jochen Wiedmann commented on XMLRPC-195:
----------------------------------------

Quoting from the XML-RPC specification that you have referenced yourself below:

    If no type is indicated, the type is string.

In other words: What Apache XML-RPC does, is a perfectly valid behaviour and the error (if
any) is on the side of the software which doesn't deal with that properly.

 A Google search for "Apache XML RPC string tag" quickly reveals possibly workarounds, as
detailed in the Apache XML RPC FAQ:

http://www.google.de/url?sa=t&rct=j&q=&esrc=s&source=web&cd=3&cad=rja&ved=0CC8QFjAC&url=http%3A%2F%2Fapache-xml.6118.n7.nabble.com%2FAdding-lt-string-gt-tag-in-XML-RPC-3-1-td29255.html&ei=hmmrUIWSB4nHswaqr4HoCg&usg=AFQjCNFaJwfP155CYYU4xzFrtweumv_V1Q

Closing this as "not a bug".

> Consider a method call (API) named 'login' that takes in 4 parameters major version (integer),
minor version (integer), user name (string) and password (string). Below code snippet explains
how I invoke this remote API.
> XmlRpcClient client = new XmlRpcClient();
> Object[] loginParams = {new Integer(2), new Integer(0), new String("user@sample.com"),
new String("password")};
> client.execute("login", loginParams);
> The four parameters are wrapped as Object array to method call named 'login'. Below is
the XML generated and passed to server hosting login API:
> <methodCall>
>   <methodName>login</methodName>
>   <params>
>     <param>
>       <value>
>         <i4>2</i4>
>       </value>
>     </param>
>     <param>
>       <value>
>         <i4>0</i4>
>       </value>
>     </param>
>     <param>
>       <value>
>         user@sample.com
>       </value>
>     </param>
>     <param>
>       <value>
>         password
>       </value>
>     </param>
>   </params>
> </methodCall>
> As you notice the user name - user@sample.com and password - password are serialized
without '<string>' tag. Is this intentional. I referred the code StringSerializer and
noticed that '<string>' tag is not passed to write method. By XML-RPC specification
http://xmlrpc.scripting.com/spec it should have been:
> :
> <value>
>  <string>
>   user@sample.com
>  </string>
> </value>
> :
> Any specific reason for this change in behavior ?
