Programming Web Services with XML-RPC is shipping. the sample chapter covers xml-rpc in java. it looks like the book maintains a pretty balanced perspective, which is refreshing:

"On the other hand, XML-RPC is definitely not appropriate in plenty of Java application situations. Much of the Enterprise JavaBeans (EJB) work already relies on RMI, and rewriting it to use XML-RPC would be a remarkable waste of time. Although a snippet of XML-RPC code might be useful as a simple bridge between an EJB-based application and code written for other environments, XML-RPC isn't designed explicitly to support the many demands of complex enterprise-scale design. Similarly, if you need to pass objects, rather than parameters, betweensystems, you should look into a more sophisticated set of tools than XML-RPC. XML-RPC lets you pass sets of parameters, not complex nested structures with associated method information, back and forth."

actually, i hadn't really been paying attention to sun's level of support for xml-based rpc mechanisms, until i read a representative's comments to the question of whether or not java programmers need soap:

"The new Java APIs that will support SOAP are JSR 67, Java API for XML Messaging (JAXM), and JSR 101, Java APIs for XML based RPC (JAX/RPC). Both of these Java APIs are generic APIs that can be used with a variety of XML messaging services(e.g., SOAP, W3C XMLP, ebXML Message Service) and XML-based RPC systems (e.g., SOAP, W3C XMLP, XML-RPC). Note that all of these XML communications systems are based on or forked from SOAP. These Java APIs will protect the Java developer from the minor differences between the various XML communications systems."

“"it is hard to be brave," said piglet, sniffing slightly, "when you're only a Very Small Animal." rabbit, who had begun to write very busily, looked up and said: "it is because you are a very small animal that you will be Useful in the adventure before us."”

[ about ]

this site chronicles the continuing adventures of my son, odin, who was unexpectedly born on the fourth of july at 25 weeks gestation, weighing 1 pound 7 ounces.

he's quite a fighter and you can always send him a postcard to the most current address listed here if you're inspired by his adventures. see the postcard project/google maps mashup to see a map of the postcards.

if you're new, you can browse the archives to catch up. and don't forget to watch a few movies that i made while we were in the neonatal intensive care unit. or if you want the abridged version and you can find a copy, you can read about his adventures in the november 2005 issue of parents magazine.
