Integrating Java and EGW 1.4 with XMLRPC - Is that possible?

xlates-2 2009-06-21 10:28:41 UTC #1

Trying to use XMLRPC apache client from Windows and call xmrpc.php on redhat. Not so easy… Help wanted in case someone knows how to integrate Java / EGW.

Original question:

"According to XMLRPC documentation there should be at least fault response if something fails. Now, only case, when fault response arrives, is when the posted request body is corrupted or empty. Another case is, when the method name != system.login. When I use system.login as method name I ALWAYS GET 200 no matter on the other arguments.

Could someone put an example message WITH AN EXAMPLE domain name - not like “your domain” for the login message? But I think it wont matter what I send, as the system never sends any “auth failed” or “invalid arguments” or nothing. Only empty… What is the matter? Should the XMLRPC work on EGW 1.4? Are there any changes compared to 1.6?"

The client is written in Java. Now I am trying to apply Apache xmlrpc client that works better. However, I dont know what args should I use, as the client is now telling me:

org.apache.xmlrpc.XmlRpcException: Incorrect parameters passed to method: Wanted struct, got string at param 1)
at org.apache.xmlrpc.client.XmlRpcStreamTransport.readResponse(XmlRpcStreamTransport.java:197)

when using:

Object[] params = new Object[]{“foo”};
Integer result = (Integer) client.execute(“system.login”, params);

What struct? I wonder why the “params” is 1-dim array instead of map with name/value pairs. Would anyone know, what params the “system.login” needs?

Im having a molologue here… but reporting progress, in case someone could help me. The core issue is calling EGW from Java. Thats what Im trying to do. For some reason, the Apache XmlRpcClient does not allow stuctures below ……

The server in EGW is expecting still and others… It seems to be pretty difficult to put that suff in. However, I tried to put “…” as string to argument for the client, but some process converted the signs to &lt… and so on (tried escaping utf8, but same result):

<?xml version="1.0" encoding="UTF-8"?>system.loginESCAPED LTstructESCAPED GT

SO - What is the way to integrate Java / EGW?
And if I go back to my manual sender, that generates XML, what should I put to the POST header in order to get appropriate response instead of 200ok and empty body?

Thanks - I have read that and al the other docs about the issue… As told, core issue is, that the Apache client wont allow “deep” structures, that the xmlrpc.php demands. At least I dont know how. And “tricking” wont work, as some <>-sign transformation occurs on the way to EGW. One option is to find out, what should be put with the XMLRPC message header, so that the POST body made according to the spec BY HAND (using Jaxb), would cause some actual transaction in the server side (as now returns happily 200ok with no body)

Resolved the issue by modifying Apache XmlRpcClient source code to be “EGW” spesific, eg. made methods such as “sendLoginRequest” and so on. The serializer can make proper XML.

That isn’t a good solution at all.
