Does WebSphere have support for MTOM and XOP?
Back in Feb. 2005, I talked about new specs from the W3C to make XML more efficient (Better Web Services Performance, Web Services Compression and Reliability, and Reliable Web Services). Two of those are MTOM and XOP. Now a customer wanted to know if WebSphere supports these.
I've also talked about the WebSphere Software Early Programs, one of which is (or at least was) the WebSphere Application Server Feature Pack for Web Services (which now has support). This feature pack is no longer in beta, it's GA (generally available); so it may no longer be considered an early program, but it is now supported for production use.
The Web Services feature pack adds support for MTOM and XOP (as explained in the info center). The package is WS-I compliant. It implements the WS-I Basic Profile 1.1. However, BP 1.1 is older than MTOM/XOP and so doesn't include them. WS-I BP 1.2 does include XOP 1.0 and SOAP 1.1 Binding for MTOM 1.0, but it's not final yet. The MTOM/XOP support in the WAS feature pack is compliant with latest draft of WS-I BP 1.2 (March 2007), which is about as close to standard as we have right now.
There was also a question about interoperability with Microsoft products. I can't speak for Microsoft (or IBM for that matter!), but Microsoft generally claims that their products are WS-I compliant. If so, then their products should eventually support WS-I BP 1.2 and therefore support MTOM and XOP. WS-I compliance also means that products from different vendors (such as those from IBM and Microsoft) are supposed to be interoperable. (See Interoperability vs. Integration and More on Interoperability vs. Integration.)
So: Yes, WebSphere now supports MTOM and XOP. To get it, install the WAS 6.1 feature pack for Web Services.
Update (Aug. 15): Note the comment from IBM's Billy Lo: He gave a presentation at Impact 2007 that demonstrated MTOM interoperability between WebSphere and Microsoft products.
Bobby Woolf: WebSphere SOA and JEE in Practice
From archive: August 2007 X
IBM is characterizing Microsoft's SOA strategy as Windows-only.
This according to "IBM chides Microsoft over SOA" (CNet). Basically, IBM supports all platforms, whereas Microsoft (IBM claims) only supports the Windows platform.
This distinction is important because a big part of the promise of SOA is to enable and simplify integration of services and applications running on multiple platforms so that they all work together as what appears to the user to be one (composite) application. SOA should integrate programs on all platforms, not just on any one platform like Windows.[Read More]
The TRS-80, one of the first home computers, has turned 30 years old.
Tandy Corporation introduced the Radio Shack TRS-80 Microcomputer on August 3, 1977, which is thirty years ago last week. It was one of the first personal/home computers; the IBM PC didn't come along until 1982 (Wikipedia says August 12, 1981). Hard to believe now, but the idea that individuals could afford to own their own computer was a big deal. ("Only six electronic digital computers would be required to satisfy the computing needs of the entire United States." (Howard Aiken, 1947))
The first TRS-80 didn't even have a diskette drive; programs loaded off of casette tape, and slowly. I remember my middle school had one and a couple of friends of mine and I would play around with it to try to figure out what it could do. It had BASIC, so you could actually program it yourself; a good thing since there wasn't much software. So BASIC became the first programming language I learned--something else I learned in school that I don't use in work/life! Well, look at me now.[Read More]
Can it be that beauty is not just in the eye of the beholder, but that in fact it's a mathematical ratio?
I'd never heard of this before, but there's a so-called "golden number," aka Phi, which is 1.618 (or perhaps it's irrational: 1.6180339887...). What we humans consider to be properly proportioned often contains this ratio. Among other things, it's the basis for a grid of the human face; the better someone's face fits this grid, the more likely he or she is to be considered beautiful. Beauty, it seems, is somewhat universally agreed upon, in terms of a face being symmetrical and properly proportioned.
This seems far fetched to me, but there's a lot of discussion dating back hundreds if not thousands of years. It may or may not simply be a myth, but it is interesting. To learn more:Read More]
