16901 of 18429 | An early look at sXBL - SVG`s XML Binding Language -- sXBL -- is an XML vocabulary being developed at the W3C as a means of mapping XML elements in arbitrary vocabularies to SVG pictures that represent those elements. For example, an XML Metadata Interchange (XMI) document can be turned into SVG code that shows the actual Unified Modeling Language (UML) diagram encoded in the XMI document. But sXBL takes the separation of presentation from content one step further: It is a generic language for rendering documents as arbitrarily complex two-dimensional pictures. This article offers an overview of this emerging and potentially powerful technology....

For example, if Schema1.xsd imports SchemaA.xsd AND SchemaB.xsd. And SchemaA.xsd AND SchemaB.xsd both import Schema2.xsd. Without this fix you will receive the following error when you compile Schema1.xsd: schemaLocation could not be resolved Right now the readme for SP1 directs you to http://support.microsoft.com/default.aspxscid=kb;en-us;890673 which instructs you to call PSS to receive the fix.  You really do want this fix and it wouldn`t be very efficient if you had to call ......

16914 of 18429 | More on wsa:To - Mark replies to my recent missive. Regarding the value of wsa:To itself, apparently Mark`s concern is:       "…that the spec didn`t require that the address go in the appropriate place in the application protocol."   I really don`t see how WS-Addressing can specify this given that the spec itself doesn`t know anything about the underlying protocols that might be used to move around SOAP messages containing wsa:* headers. And even if the WG were tasked with providing normative bindings for, say, HTTP, SMTP, TCP and UDP, the value of the wsa:To may or may not make sense for one or more of those protocols.   Now, in *many* cases, the value of the wsa:To will be an HTTP URI. And the SOAP messa......

16915 of 18429 | Simplify WSDL composition with the ETTK WSDL Port Type Aggregator - These days the task of creating WSDL files has become increasingly complex and time-consuming. This scenario is worsened due to the sheer number of Web Services specifications available. A WSDL document willing to take advantage of these specifications is required to incorporate elements from them. This is generally implemented through a crude and error prone cut-and-paste process. The featured tool presents a graphical and intuitive way to aggregate constructs from several different WSDL sources into a single document....

16921 of 18429 | Using SLAs in a Web Services context, Part 7: Mitigating risks of vulnerabilities with a SLA guarantee - In Part 7 of this series, Judith M. Myerson explains how developers can mitigate risks of vulnerabilities of Web services in a heterogeneous Service-Oriented Architecture (SOA) to reduce the chances of adversely impacting the service-level agreement (SLA) guarantee for uptime availability. She goes beyond the Advanced Vulnerability Description Language (AVDL) by addressing the issues of determining interruption thresholds for a Web service that, for example, has not completed the task of responding to a request for vulnerability information over the HTTP. This is important as the Web service is designed to interact quickly with other Web services and non-Web services in the SOA....

Business Process can be described in two ways: - Executable business processes, which model actual behavior of a participant in a business interaction. - Business protocols(abstract processes), which use process descriptions that specify the mutually visible message exchange behavior of each of the parties involved in the protocol, without revealing their internal behavior. BEPL4WS provides a language for the formal specification of business processes and business interaction protocols. BPEL4WS extends the Web Services interaction model and enables it to support business transactions. BPEL......

16935 of 18429 | To the TAG with you... - Well, this will be interesting. Mark Baker succeeded in his quest to get the W3C Technical Architecture group to look at his beef with WS-Addressing. I’m very curious to see how this plays out. Let me attempt to summarize Mark’s issue. WS-Addressing defines an abstract property called “Address” that reflects the destination of the message. When EPR’s are serialized using the SOAP binding, this URI gets squirted into a wsa:To header. Bindings to other formats might put that information in a different place. Mark is of the opinion that if the “Address” abstract property represents the destination of the message, then it......

16939 of 18429 | Create SecurityContextTokens without X509 Certs - So I wanted to roll my own SecurityContextToken (SCT) service.  Not because I want to reinvent the wheel, but because I did not want to have to use X509 certs and because I could not figure out how to issue SCTs using soap.tcp at the server.  All the documentation addresses using IIS web service and ASP.  First a word on SCTs as they can be a bit confusing.   The goal is to authenticate to the server and get a SCT at both sides.  The idea is you can only get a SCT if you authenticate at the server.  The SCTs at both sides have a random 16 byte secret key that both sides can use to encrypt the rest of the session (using AES/Rijndael or other.)  This is very similar to how SSL works.  SCTs ar......

16940 of 18429 | CSS vs XSL - Last Week Xml.com posted an article by HakonWium Lie and Michael Day called "Printing XML: Why CSS is Better than XSL".  It was a pretty good read on why, for printing and web page rendering purposes, CSS is better than XSLT.  The authors are careful to point out that XSL`s functionallity is far more robust than CSS and is better for a variety of uses, but that for printing, CSS may be the better alternative.  As a XML guys and a  blogger who has grand ideas that he might be able to design a cool-looking blog one day, rather than use one of the various standard templates available to me, I`ve often thought that XSL would be a great way to format a blog, with an XML data model benieth. It st......

16941 of 18429 | Opacity - In reference to my recent post on EPR`s, RefP`s, and MSDN2, Savas says that I might be forgetting about EPR opacity. I`ve read Savas` previous discussions of this topic on the WS-Addressing list. I didn`t feel prepared to disagree with them in that forum, but I`ll do so now. It`s not so much that I forgot about EPR opacity as I made a conscious decisions that it really didn`t apply in the scenarios I`m discussing. Backing up a bit, EPR opacity is the principle that says that when I`m given an EPR, I shouldn`t look inside of it to gain any information about the thing to which it is referring. Opacity is a general characteristic of addressing mechanisms like UR......

16942 of 18429 | EPR`s, RefP`s, and MSDN2 - Tim Ewald`s recent MSDN article on the details of the new MSDN2 URL scheme is really quite fascinating. The implementation details are pretty cool, but what really grabbed my brain was his discussion of identifiers at the top of the article. At least in my head, it related nicely to the recent discussion of ReferenceProperties and identifiers in the context of WS-Addressing. One of the things that has bugged me about the discussions of RefP`s has been a lack of a proper motivating example -- the canonical use cases of message correlation and transaction ID`s have been beaten into the ground, and people have been reaching really hard to find other examples wher......

16943 of 18429 | Mitigating XPath Injection Attacks in .NET - It`s already 2005 and everybody`s aware of SQL injection attacks nowadays. But it`s silly to think that this kind of attack is only about SQL, right SQL injection is just one particular case of a general code injection attack - when somebody too gullible allows user input to become a part of an executable code. So it`s always bothers me when I see how often people (even XML geeks) are building XPath expressions concatenating them with user input. Admit it - that`s common practice to have something like customers.SelectNodes("//customer[@name=`" + txtUser.Text + "` and @password=`" + txtPassword.Text + "`]") which is just a front door open for any evil person, which knows a litt......

16945 of 18429 | Using Java - I`ve been working with Java lately because it`s what Mindreef uses to build SOAPscope and our next thing. As a dedicated MS platform supporter for many many years, it`s been a pretty interesting experience, especially coming off 18 months working on MSDN2, which we implemented with Whidbey. There are three main things I`ve noticed. First, once you environment is set up, the only difference between Java and C# is the idioms. Yes, C# has some nice features that Java does not (some will come in 1.5), but they aren`t enough of an issue to make you go one way or the other. The IDEs for Java are uglier (well, maybe not Eclipse) and clunkier, but they offer richer features for cutting OO code. The......

16946 of 18429 | What do people mean by document-oriented - Lot`s of WS zealots complain that too many developes think of Web services as just another RPC when it should be seen as a message-oriented or document-oriented instead.

Here are some possible interpretations: Don`t break apart the input/output messages and map their contents to individual method arguments; make a method with one input message parameter and one output message parameter instead Just like (1), but the messages should be exposed as XML You don`t map request/response pairs to method calls at all, come up with some other programming model The programming model may or may not matter, what really matters is whether the root elemen......

16947 of 18429 | BizTalk Server 2004: Generating C# source files - Some time ago I published a utility on GotDotNet.com which dumps the temporary C# source code files generated by BizTalk during compilation. The utility works quite well, but cannot always dump all the files because it is unable to prevent BizTalk from deleting files once compilation is complete. BizTalk sometimes gets there first, removing the temporary files before the utility has a chance to copy them to the target dump location. Another problem is that the files have meaningless names, and are therefore difficult to trace back to the corresponding BizTalk artefacts. The utility is cool…but quite unnecessary. It turns out that Microsoft has implemented an undocumented registry setting to......

16950 of 18429 | BizTalk FTP Receive Adapter might fail on large files - Just saw that my last serious post dates back to november 5th. A lot has happened in between, like a project with no internet connection (aaargh), two weeks of serious illness and some BizTalk deployment issues on one of my projects. It`s one of those issues that I like to blog about.    We use the BizTalk FTP Receive adapter to pull down XML files that might become up to several 100 MBs in size. Those files failed in our case on the exception `could not delete file` (which referred to file on the FTP server). The file was not processed by BizTalk. The cause was actually quite simple.   The FTP Adapter works as follows: - Regularly poll the FTP site for new files - Download any found files ......
