Hi!
I made the post below almost a month ago. I can still make use of any
information since I haven't had time to look into it myself yet.
Regards,
Jimisola

Subject: HttpClient - usage etc
Hi!
I have server-client solution where we have problem with timeouts. Under 1.4
you
have to use properties to set read and/connection timeout for the whole
program.
So, I was delighted to see that HttpClient is available in XMLRPC-2.0 as
timeouts can be set directly on the HttpClient.
However, I spend some time last night trying to figure out 1) how to actually
use it and 2) how to set timeouts.
Is there no factory class to use with XmlRpcClient constructor for use of
HttpClient. The
DefaultXmlRpcTransportFactory seems to be more than just a plain factory class
as I in createTransportFactory noticed the Reflection construction call to a
constructor with signature java.util.Properties properties
(CONSTRUCTOR_SIGNATURE_STRING).
So, my questions are:
1) How do use Commons HttpClient and also set additional properties? Do I need
to create a new factory class or extend DefaultXmlRpcTransportFactory and then
adjust it after my needs? Or can I use DefaultXmlRpcTransportFactory as is -
in
some way that I haven't been able to figure out yet? (might be interesting
with
an example on the web site)
2) It says that "Note: Currently this transport is not thread safe":
http://ws.apache.org/xmlrpc/apidocs/index.html
What exactly does this mean? To refer to item 52 in Effective Java, is it:
- conditionally thread-safe: thread-safe in methods are called in right
sequence
- thread-compatible: thread-safe if all methods have external synchronization
(e.g. Collection classes)
- thread-hostile: not thread-safe even if all methods have external
synchronization
Read on that " HttpClient is fully thread-safe when used with a thread-safe
connection manager such as MultiThreadedHttpConnectionManager " (more info on
http://jakarta.apache.org/commons/httpclient/threading.html).
I am not very familiar with HttpClient, so bear with my questions. Does this
thread-safety only apply for HttpClient 3.0 (which seems to be close now)?
Kind regards,
Jimisola
