• xsl literal with <xsl:if>

  - by Elena

  Hi, I have to write a very simple code in xsl: IF column=0 if result = .34 set background color to green and write $result, but if result = 0.10 set background color to white and write the word "QQQ" and what doesn't work is: <xsl:if test="$result = 0.35 and $column = 0"> <xsl:attribute name='background-color'>#669933</xsl:attribute> <xsl:value-of select="result"/> </xsl:if> <xsl:if test="$result = 0.10"> <xsl:value-of select="QQQ"/> </xsl:if> any suggestions? thanks in advance

• JAMES Mailet development process

  - by itsadok

  I'm starting a project that involves writing mailets for Apache James. As far as I can tell, the only way to test a change in my code (on Windows) is through the following steps: Compile the mailet code Build a jar file containing the mailet Copy the jar file into the apps/james/SAR-INF/lib directory Start JAMES from run.bat Run test Stop JAMES by telneting to port 4555 and issuing a shutdown command (I guess on Linux a SIGTERM would suffice) I can automate all these steps using Ant and some scripting magic, but I was wondering if I was missing something. Does anyone here have experience developing mailets? Did you use a similar process, or is there an easier way? For example, is there a way to make a running James instance reload the mailets JAR?

• Compiling program that uses libpcap on Mac OSX using iPhone 3.1.1 SDK for use on iPhone

  - by Alan

  Hey SOV users, I have a question that I'm hoping some iPhone Developers may be able to help with. I had a look at statically compiling a binary on my Mac and moving it over to the iPhone for execution. I have managed to get this bit of it working by installing the iPhone 3.1.3 SDK on my Mac and setting the architecture to the iPhone in the gcc line as follows; /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc -I ~/Downloads/libpcap-1.1.1/pcap-compiled/ -arch armv6 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk -o test test.c I have managed to successfully compile a "Hello World" C program and executed it on the iPhone with success. e.g. include int main() { printf("Hello, World!\n"); return(0); } This worked a charm. I am also using 'ldid' to sign the application (but only if necessary). Anyways, I have been trying to get a program to compile which uses libpcap (http://www.tcpdump.org/) but with little success. I have downloaded and installed libpcap-1.1.1 on my mac and set the configure --prefix to /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk/usr/local and build the application. I then saw that the includes actually reside in Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk/usr/includes and so moved the Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk/usr/local/include files (which contained only the pcap stuff) to the correct location. I then attempted to compile the test program using; /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc -I /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.1.3.sdk/usr/include/ -arch armv6 -isysroot /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS2.1.sdk -o pcap pcap.c -lpcap This worked a lot better than other tests but produces an error; i.e. ld: library not found for -lcrt1.o collect2: ld returned 1 exit status Do you have any ideas as to how I can do this successfully? I've tried a load of different things but none seem to be successful. Basically, I just want to install (or add) some headers to the existing iPhoneOS SDK for use in compiling programs. Any ideas? Cheers, A

• TDD - How to start really thinking TDD?

  - by user74825

  I have been reading about Agile, XP methodologies and TDDs. I have been in projects which states it needs to do TDD, but most of the tests are somehow integration tests or during the course of project TDD is forgotten in effort to finish codes faster. So, as far as my case goes, I have written unit tests, but I find myself going to start writing code first instead of writing a test. I feel there's a thought / design / paradigm change which is actually huge. So, though one really believes in TDD, you actually end up going back old style because of time pressure / project deliverables. I have few classes where I have pure unit tested code, but I can't seem to continue with the process, when mocks come into picture. Also, I see at times : "isn't it too trivial to write a test for it" syndrome. How do you guys think I should handle this?

• Acrobat Reader ActiveX in WebBrowser stealing focus [C#]

  - by Maciej

  I'm using webBrowser.Navigate(url) control to display page. I noticed this action steals focus from current control (grid) and than I have problem to focus grid back (tired myGrid.Focus, .Select etc...) This is really annoying behaviour of browser... Does anyone knows how to prevent focus stealing by Browser or (if not) hot to force to focus control back ? EDIT: I've also tried webBrowser.DocumentCompleted event to focus back to grid EDIT 2 Good case to test this is openning PDF files webBrowser.Navigate(@"C:\TEMP\test.pdf") I believe this is ActiveX issue. On first glance it looks that this is not problem with focusing control but loosing entire Form focus... EDIT 3 I tried another approach: Form keyPress event: I thought I can capture form's keyPress and move focus from WebBrowser / AdobeReader ActiveX to my control. But surprisingly event is not fired! Looks Reader taken all control and there is no way to do anything programically until you do mouse click on (at least) form's caption Any advice (s) ?

• JUnit Parameterized Runner and mvn Surefire Report integration

  - by fraido

  I'm using the Junit Parameterized Runner and the Maven Plugin Surefire Report to generate detailed reports during the mvn site phase. I've something like this @RunWith(Parameterized.class) public class MyTest { private String string1; private String string2; @Parameterized.Parameters public static Collection params() { return Arrays.asList(new String[][] { { "1", "2"}, { "3", "4"}, { "5", "6"} }); } public MyTest(String string1, String string2) { this.string1 = string1; this.string2 = string2; } @Test public void myTestMethod() { ... } @Test public void myOtherTestMethod() { ... } The report shows something like myTestMethod[0] 0.018 myTestMethod[1] 0.009 myTestMethod[2] 0.009 ... myOtherTestMethod[0] 0.018 myOtherTestMethod[1] 0.009 myOtherTestMethod[2] 0.009 ... Is there a way to display something else rather than the iteration number [0]..[1]..etc.. The constructor parameters would be a much better information. For example myTestMethod["1", "2"] 0.018 ...

• SQL Server and Hyper-V Dynamic Memory Part 2

  - by SQLOS Team

  Part 1 of this series was an introduction and overview of Hyper-V Dynamic Memory. This part looks at SQL Server memory management and how the SQL engine responds to changing OS memory conditions.   Part 2: SQL Server Memory Management As with any Windows process, sqlserver.exe has a virtual address space (VAS) of 4GB on 32-bit and 8TB in 64-bit editions. Pages in its VAS are mapped to pages in physical memory when the memory is committed and referenced for the first time. The collection of VAS pages that have been recently referenced is known as the Working Set. How and when SQL Server allocates virtual memory and grows its working set depends on the memory model it uses. SQL Server supports three basic memory models:   1. Conventional Memory Model   The Conventional model is the default SQL Server memory model and has the following properties: - Dynamic - can grow or shrink its working set in response to load and external (operating system) memory conditions. - OS uses 4K pages – (not to be confused with SQL Server “pages” which are 8K regions of committed memory).- Pageable - Can be paged out to disk by the operating system.   2. Locked Page Model The locked page memory model is set when SQL Server is started with "Lock Pages in Memory" privilege*. It has the following characteristics: - Dynamic - can grow or shrink its working set in the same way as the Conventional model.- OS uses 4K pages - Non-Pageable – When memory is committed it is locked in memory, meaning that it will remain backed by physical memory and will not be paged out by the operating system. A common misconception is to interpret "locked" as non-dynamic. A SQL Server instance using the locked page memory model will grow and shrink (allocate memory and release memory) in response to changing workload and OS memory conditions in the same way as it does with the conventional model.   This is an important consideration when we look at Hyper-V Dynamic Memory – “locked” memory works perfectly well with “dynamic” memory.   * Note in “Denali” (Standard Edition and above), and in SQL 2008 R2 64-bit (Enterprise and above editions) the Lock Pages in Memory privilege is all that is required to set this model. In 2008 R2 64-Bit standard edition it also requires trace flag 845 to be set, in 2008 R2 32-bit editions it requires sp_configure 'awe enabled' 1.   3. Large Page Model The Large page model is set using trace flag 834 and potentially offers a small performance boost for systems that are configured with large pages. It is characterized by: - Static - memory is allocated at startup and does not change. - OS uses large (>2MB) pages - Non-Pageable The large page model is supported with Hyper-V Dynamic Memory (and Hyper-V also supports large pages), but you get no benefit from using Dynamic Memory with this model since SQL Server memory does not grow or shrink. The rest of this article will focus on the locked and conventional SQL Server memory models.   When does SQL Server grow? For “dynamic” configurations (Conventional and Locked memory models), the sqlservr.exe process grows – allocates and commits memory from the OS – in response to a workload. As much memory is allocated as is required to optimally run the query and buffer data for future queries, subject to limitations imposed by:   - SQL Server max server memory setting. If this configuration option is set, the buffer pool is not allowed to grow to more than this value. In SQL Server 2008 this value represents single page allocations, and in “Denali” it represents any size page allocations and also managed CLR procedure allocations.   - Memory signals from OS. The operating system sets a signal on memory resource notification objects to indicate whether it has memory available or whether it is low on available memory. If there is only 32MB free for every 4GB of memory a low memory signal is set, which continues until 64MB/4GB is free. If there is 96MB/4GB free the operating system sets a high memory signal. SQL Server only allocates memory when the high memory signal is set.   To summarize, for SQL Server to grow you need three conditions: a workload, max server memory setting higher than the current allocation, high memory signals from the OS.    When does SQL Server shrink caches? SQL Server as a rule does not like to return memory to the OS, but it will shrink its caches in response to memory pressure. Memory pressure can be divided into “internal” and “external”.   - External memory pressure occurs when the operating system is running low on memory and low memory signals are set. The SQL Server Resource Monitor checks for low memory signals approximately every 5 seconds and it will attempt to free memory until the signals stop.   To free memory SQL Server does the following: ·         Frees unused memory. ·         Notifies Memory Manager Clients to release memory o   Caches – Free unreferenced cache objects. o   Buffer pool - Based on oldest access times.   The freed memory is released back to the operating system. This process continues until the low memory resource notifications stop.    - Internal memory pressure occurs when the size of different caches and allocations increase but the SQL Server process needs to keep its total memory within a target value. For example if max server memory is set and certain caches are growing large, it will cause SQL to free memory for re-use internally, but not to release memory back to the OS. If you lower the value of max server memory you will generate internal memory pressure that will cause SQL to release memory back to the OS.    Memory pressure handling has not changed much since SQL 2005 and it was described in detail in a blog post by Slava Oks.   Note that SQL Server Express is an exception to the above behavior. Unlike other editions it does not assume it is the most important process running on the system but tries to be more “desktop” friendly. It will empty its working set after a period of inactivity.   How does SQL Server respond to changing OS memory?    In SQL Server 2005 support for Hot-Add memory was introduced. This feature, available in Enterprise and above editions, allows the server to make use of any extra physical memory that was added after SQL Server started. Being able to add physical memory when the system is running is limited to specialized hardware, but with the Hyper-V Dynamic Memory feature, when new memory is allocated to a guest virtual machine, it looks like hot-add physical memory to the guest. What this means is that thanks to the hot-add memory feature, SQL Server 2005 and higher can dynamically grow if more “physical” memory is granted to a guest VM by Hyper-V dynamic memory.   SQL Server checks OS memory every second and dynamically adjusts its “target” (based on available OS memory and max server memory) accordingly.   In “Denali” Standard Edition will also have sqlserver.exe support for hot-add memory when running virtualized (i.e. detecting and acting on Hyper-V Dynamic Memory allocations).   How does a SQL Server workload in a guest VM impact Hyper-V dynamic memory scheduling?   When a SQL workload causes the sqlserver.exe process to grow its working set, the Hyper-V memory scheduler will detect memory pressure in the guest VM and add memory to it. SQL Server will then detect the extra memory and grow according to workload demand. In our tests we have seen this feedback process cause a guest VM to grow quickly in response to SQL workload - we are still working on characterizing this ramp-up.    How does SQL Server respond when Hyper-V removes memory from a guest VM through ballooning?   If pressure from other VM's cause Hyper-V Dynamic Memory to take memory away from a VM through ballooning (allocating memory with a virtual device driver and returning it to the host OS), Windows Memory Manager will page out unlocked portions of memory and signal low resource notification events. When SQL Server detects these events it will shrink memory until the low memory notifications stop (see cache shrinking description above).    This raises another question. Can we make SQL Server release memory more readily and hence behave more "dynamically" without compromising performance? In certain circumstances where the application workload is predictable it may be possible to have a job which varies "max server memory" according to need, lowering it when the engine is inactive and raising it before a period of activity. This would have limited applicaability but it is something we're looking into.   What Memory Management changes are there in SQL Server “Denali”?   In SQL Server “Denali” (aka SQL11) the Memory Manager has been re-written to be more efficient. The main changes are summarized in this post. An important change with respect to Hyper-V Dynamic Memory support is that now the max server memory setting includes any size page allocations and managed CLR procedure allocations it now represents a closer approximation to total sqlserver.exe memory usage. This makes it easier to calculate a value for max server memory, which becomes important when configuring virtual machines to work well with Hyper-V Dynamic Memory Startup and Maximum RAM settings.   Another important change is no more AWE or hot-add support for 32-bit edition. This means if you're running a 32-bit edition of Denali you're limited to a 4GB address space and will not be able to take advantage of dynamically added OS memory that wasn't present when SQL Server started (though Hyper-V Dynamic Memory is still a supported configuration).   In part 3 we’ll develop some best practices for configuring and using SQL Server with Dynamic Memory.

• Windows Vista/Win7 Privilege Problem: SeDebugPrivilege & OpenProcess

  - by KevenK

  Everything I've been able to find about escalating to the appropriate privileges for my needs has agreed with my current methods, but the problem exists. I'm hoping maybe someone has some Windows Vista/Win7 internals experience that might shine some light where there is only darkness. I'm sure this will get long, but please bare with me. Context: I'm working on an app that requires accessing the memory of other processes on the current machine. This, obviously, requires administrator rights. It also requires SeDebugPrivilege, which I believe myself to be acquiring correctly, although I question if more privileges aren't necessary and thus the cause of my problems. Code has so far worked successfully on all versions of Windows XP, and on my test Vista32 and Win7x64 environments. Process: Program will Always be run with Administrator Rights. This can be assumed throughout this post. Escalating the current process's Access Token to include SeDebugPrivilege rights. Using EnumProcesses to create a list of current PIDs on the system Opening a handle using OpenProcess with PROCESS_ALL_ACCESS access rights Using ReadProcessMemory to read the memory of the other process. Problem: Everything has been working fine during development and my personal testing (including Windows XP 32 & 64, Windows Vista 32, and Windows 7 x64). However, during a test deployment onto both Windows Vista(32-bit) and Windows 7(64-bit) machines of a colleague, there seems to be a privilege/rights problem with OpenProcess failing with a generic Access Denied error. This occurs both when running as a limited User (as would be expected) and also when run explicitly as Administrator (Right-click Run as Administrator and when run from an Administrator level command prompt). However, this problem has been unreproducible for myself in my test environment. I have witnessed the problem first hand, so I trust that the problem exists. The only difference that I can discern between the actual environment and my test environment is that the actual error is occurring when using a Domain Administrator account at the UAC prompt, whereas my tests (which work with no errors) use a local administrator account at the UAC prompt. It appears that although the credentials being used allow UAC to 'run as administrator', the process is still not obtaining the correct rights to be able to OpenProcess on another process. I am not familiar enough with the internals of Vista/Win7 to know what this might be, and I am hoping someone has an idea of what could be the cause. The Kicker: The person who has reported this error, and who's environment can regularly reproduce this bug, has a small application named along the lines of RunWithDebugEnabled which is a small bootstrap program which appears to escalate its own privileges and then launch the executable passed to it (thus inheriting the escalated privileges). When run with this program, using the same Domain Administrator credentials at UAC prompt, the program works correctly and is able to successfully call OpenProcess and operates as intended. So this is definitely a problem with acquiring the correct privileges, and it is known that the Domain Administrator account is an administrator account that should be able to access the correct rights. (Obviously obtaining this source code would be great, but I wouldn't be here if that were possible). Notes: As noted, the errors reported by the failed OpenProcess attempts are Access Denied. According to MSDN documentation of OpenProcess: If the caller has enabled the SeDebugPrivilege privilege, the requested access is granted regardless of the contents of the security descriptor. This leads me to believe that perhaps there is a problem under these conditions either with (1) Obtaining SeDebugPrivileges or (2) Requiring other privileges which have not been mentioned in any MSDN documentation, and which might differ between a Domain Administrator account and a Local Administrator account Sample Code: void sample() { ///////////////////////////////////////////////////////// // Note: Enabling SeDebugPrivilege adapted from sample // MSDN @ http://msdn.microsoft.com/en-us/library/aa446619%28VS.85%29.aspx // Enable SeDebugPrivilege HANDLE hToken = NULL; TOKEN_PRIVILEGES tokenPriv; LUID luidDebug; if(OpenProcessToken(GetCurrentProcess(), TOKEN_ADJUST_PRIVILEGES, &hToken) != FALSE) { if(LookupPrivilegeValue(NULL, SE_DEBUG_NAME, &luidDebug) != FALSE) { tokenPriv.PrivilegeCount = 1; tokenPriv.Privileges[0].Luid = luidDebug; tokenPriv.Privileges[0].Attributes = SE_PRIVILEGE_ENABLED; if(AdjustTokenPrivileges(hToken, FALSE, &tokenPriv, 0, NULL, NULL) != FALSE) { // Always successful, even in the cases which lead to OpenProcess failure cout << "SUCCESSFULLY CHANGED TOKEN PRIVILEGES" << endl; } else { cout << "FAILED TO CHANGE TOKEN PRIVILEGES, CODE: " << GetLastError() << endl; } } } CloseHandle(hToken); // Enable SeDebugPrivilege ///////////////////////////////////////////////////////// vector<DWORD> pidList = getPIDs(); // Method that simply enumerates all current process IDs ///////////////////////////////////////////////////////// // Attempt to open processes for(int i = 0; i < pidList.size(); ++i) { HANDLE hProcess = NULL; hProcess = OpenProcess(PROCESS_ALL_ACCESS, FALSE, pidList[i]); if(hProcess == NULL) { // Error is occurring here under the given conditions cout << "Error opening process PID(" << pidList[i] << "): " << GetLastError() << endl; } CloseHandle(hProcess); } // Attempt to open processes ///////////////////////////////////////////////////////// } Thanks! If anyone has some insight into what possible permissions/privileges/rights/etc that I may be missing to correctly open another process (Assuming the executable has been properly "Run as Administrator"ed) on Windows Vista and Windows 7 under the above conditions, it would be most greatly appreciated. I wouldn't be here if I weren't absolutely stumped, but I'm hopeful that once again the experience and knowledge of the group shines bright. I thank you for taking the time to read this wall of text. The good intentions alone are appreciated, thanks for being the type of person that makes SO so useful to all!

• NFS to NFS mount

  - by dude

  I have a machine that I need to bridge NFS files to. Can I mount an NFS directory on machine2 from machine1 and then mount the mounted NFS directory on machine2 on machine3 via NFS? Do you see any problems with that? I am basically bridging some subnet domains this way, in a certain fashion. My development machine is on a different and separate (unbridged) than where I would like to use the files, and I would like this machine1(dev machine) - machine2(passthrough machine) - machine3(test machine) connection. And no there is no way to move the test machine as it's a chassis :) and it's two buildings away.

• How to use and/or localize DisplayAttribute with ASP.NET MVC2?

  - by asp_net

  I am trying to figure out how to get the DisplayAttribute in my MVC 2 ViewModel to work with the Html.LabelFor() helper. Neither public class TestModel { [Display(ResourceType = typeof(Localization.Labels))] public string Text { get; set; } } nor public class TestModel { [Display(Name = "test")] public string Text { get; set; } } seem to work. Localizing the Required Attribute works as expected: [Required(ErrorMessageResourceName = "Test", ErrorMessageResourceType = typeof(Localization.Labels))] I am using VS2010 RC. Has anybody got that running?

• Oracle Fusion Applications: Changing the Game

  - by kellsey.ruppel(at)oracle.com

  Originally posted in the Oracle Profit Magazine, November 2010 Edition. When the order processing system red-flags a customer's credit status, the IT department doesn't get the customer's call. When a supplier misses a delivery date for a key automotive assembly, it's not the CIO who has to answer for the error. Knowledge workers (known in IT circles as "users") are on the front lines when an exception occurs in an established business process. They're also the ones who study sales trends to decide when to open a new store in an up-and-coming neighborhood, which products are most profitable, how employee skill sets are evolving, and which suppliers are most efficient. In short, knowledge workers are masters of business as unusual. Traditional enterprise resource planning (ERP) systems and other familiar enterprise applications excel at automating, managing, and executing standard business processes. These programs shine when everything goes as planned. Life gets even trickier when a traditional application needs to be extended with a new service or an extra step is added to a business process when new products are brought to market, divisions are merged, or companies are acquired. Monolithic applications often need the IT department to step in and make the necessary adjustments--incurring additional costs and delays. Until now. When Oracle unveiled the much-anticipated family of Oracle Fusion Applications at Oracle OpenWorld in September 2010, knowledge workers in particular had a lot to cheer about. Business users will soon have ready access to analytical information and collaboration tools in the context of what they are working on, so they can make better decisions when problems or opportunities arise. Additionally, the Oracle Fusion Applications platform will make it easy for business users to tweak processes, create new capabilities, and find information, often without the need for IT department assistance and while still following company guidelines. And IT leaders will be happy to hear about new deployment options, guided implementation and setup tools, and cost-saving management capabilities. Just as important, the underlying technologies in Oracle Fusion Applications will allow organizations to choose among their existing investments and next-generation enterprise applications so they can introduce innovations at a pace that makes the most business and financial sense. "Oracle Fusion Applications are architected so you don't have to do rip and replace," says Jim Hayes, managing director of the consulting firm Accenture. "That's very important for creating a business case that will get through the steering committee and be approved by the board. It shows you can drive value and make a difference in the near term." For these and other reasons, analysts and early adopters are calling Oracle Fusion Applications a game changer for enterprise customers. The differences become apparent in three key areas: the way we innovate, work, and adopt technology. Game Changer #1: New Standard for InnovationChange is a constant challenge for most businesses, whether the catalysts are market dynamics, new competition, or the ever-expanding regulatory environment. And, in an ongoing effort to differentiate, business leaders are constantly looking for new ways to do business, serve constituents, and bring new products and services to market. In addition, companies face significant costs to keep their applications up-to-date. For example, when a company adds new suppliers to a procurement system, the IT shop typically has to invest time, effort, and even consulting fees for custom integrations that allow various ERP systems to communicate with each other. Oracle Fusion Applications were built on Web services and a modular SOA foundation to ease customizations and integration activities among all applications--whether from Oracle or another vendor. Interfaces and updates written in ubiquitous Java, rather than a proprietary coding language, allow organizations to tap into existing in-house technical skills rather than seek expensive outside specialists. And with SOA, organizations can extend a feature set or integrate with other SOA environments by combining Web services such as "look up customer" into a new business process managed by the BPEL orchestration engine. Flexibility like this has long-term implications. "Because users capture these changes at a higher metadata layer, not in the application's code, changes and additions are protected even as new versions of Oracle Fusion Applications are released," says Steve Miranda, senior vice president of applications development at Oracle. "This is a much more sustainable approach because you don't incur costly customizations that prevent upgrades and other innovations." And changes are easier to make: if one change is made in the metadata, that change is automatically reflected throughout the application interface, business intelligence, business process, and business logic. Game Changer #2: New Standard for WorkBoosting productivity comes down to doing the basics right: running business processes more efficiently and managing exceptions more effectively, so users can accomplish more in the course of a day or spend more quality time with the most profitable customers. The fastest way to improve process efficiency is to reduce the number of steps it takes to execute common tasks, such as ordering office equipment from an internal procurement system. Oracle Fusion Applications will deliver a complete role-based user experience with business intelligence and collaboration capabilities provided in the context of the work at hand. "We created every Oracle Fusion Applications screen by asking 'What does the user need to know?' 'What does he or she need to do?' and 'Who do they need to work with to get the job done?'" Miranda explains. So when the sales department heads need new laptops, the self-service procurement screen will not only display a list of approved vendors and configurations, but also a running list of reviews by coworkers who recently purchased the various models. Embedded intelligence may also display prevailing delivery lead times based on actual order histories, not the generic shipping dates vendors may quote. The pervasive business intelligence serves many other business activities across all areas of the enterprise. For example, a manager considering whether to promote a direct report can see the person's employee profile, with a salary history, appraisal summaries, and a rundown of skills and training. This approach to business intelligence also has implications for supply chain management. "One of the challenges at Ingersoll Rand is lack of visibility in our supply chain," says Mike Macrie, global director of enterprise applications for global industrial firm Ingersoll Rand. "Oracle Fusion Applications are going to provide the embedded intelligence to give us that visibility and give us the ability to analyze those orders at any point in our supply chain." Oracle Fusion Applications will also create a "role-based user experience" that displays a work list of events that need attention, based on user job function. Role awareness guides users with daily lists of action items and exceptions. So a credit manager may see seven invoices with discounts that are about to expire or 12 suppliers that have been put on hold because credit memos are awaiting approval. Individualization extends to the search capabilities of Oracle Fusion Applications. The platform uses Web-style search screens powered by an Oracle enterprise search engine, with a security framework that filters search results so individuals will only see the internal information they're authorized to access. A further aid to productivity is Oracle Fusion Applications' integration with Web 2.0 collaboration and social networking resources for business environments. Hover-over text will reveal relevant contact information whenever the name of a person appears in an Oracle Fusion Application. Users can connect via an online chat, phone call, or instant message without leaving the main application, reducing the time required for an accounts payable staffer to resolve a mismatch between an invoiced charge and the service record, for example. Addresses of suppliers, customers, or partners will also initiate hover-over text to show contact details and Web-based maps. Finally, Oracle Fusion Applications will promote a new way of working with purpose-driven communities that can bring new efficiencies to everything from cultivating sales leads to managing new projects. As soon as a lead or project materializes, the applications will automatically gather relevant participants into an online community that shares member contact information, schedules, discussion forums, and Wiki pages. "Oracle Fusion Applications will allow us to take it to the next level with embedded Web 2.0 tools and the embedded analytics," says Steve Printz, CIO and vice president, supply chain management, at window-and-door manufacturer Pella. "[This] allows those employees today who are processing transactions to really contribute to the success of the company and become decision-makers." Game Changer #3: New Standard for Technology AdoptionAs IT becomes a dominant component of how businesses run and compete, organizations need to lower the cost of implementing applications and introducing new application features. In the past, rolling out new code often required creating a test bed system, moving beta code to a separate system for user feedback, and--once all the revisions were made--moving version one of the software onto production systems, where business users could finally get the needed new features. Oracle Fusion Applications will use a dedicated setup manager application to streamline this process. First, the setup manager will help scope out the project, querying users about their requirements. "From those questions and answers we determine the steps and the order of those steps that will enable that task," Miranda says. Next, system utilities will assign tasks to owners, track completion status, and monitor the overall status of a programming effort. Oracle Fusion Applications can then recommend Web services that allow users to migrate setup choices and steps across all the various deployments of the application. Those setup capabilities automate the migration from test systems to production systems, as well as between different business units that may be using the same application. "The self-service ability of the setup manager helps business users change setups with very little intervention from the IT team," says Ravi Kumar, vice president at IT services company Infosys. "That to me is a big difference from how we've viewed enterprise applications before." For additional flexibility, organizations will be able to adopt Oracle Fusion Applications modules in either of two modes: a single-instance alternative uses one database for all Oracle Fusion Applications, while a "pillar mode" creates separate databases to underpin each application. This means IT departments running any one of Oracle's applications or even third-party applications can plug Oracle Fusion Applications modules into their environment and see additional business value created on top of their existing systems. And Oracle Fusion Applications offer a hybrid approach to deployment. The applications are all software-as-a-service-ready, so customers can choose on-premises, public or private cloud, or a combination of these to suit their business needs. It's that combination of flexibility and a roadmap for the future that may be the biggest game changer of all. "The Oracle Fusion Applications architecture allows us to migrate our company at a pace that's consistent with our business strategy, whereas before we might have had to do it with a massive upgrade," says Macrie of Ingersoll Rand. "We're looking forward to that architecture to really give us more flexibility in how we migrate over time."

• Asp.Net MVC EnableClientValidation doesnt work.

  - by Farrell

  I want as well as Client Side Validation as Server Side Validation. I realized this as the following: Model: ( The model has a DataModel(dbml) which contains the Test class ) namespace MyProject.TestProject { [MetadataType(typeof(TestMetaData))] public partial class Test { } public class TestMetaData { [Required(ErrorMessage="Please enter a name.")] [StringLength(50)] public string Name { get; set; } } } Controller is nothing special. The View: <% Html.EnableClientValidation(); %> <% using (Ajax.BeginForm("Index", "Test", FormMethod.Post, new AjaxOptions {}, new { enctype = "multipart/form-data" })) {%> <%= Html.AntiForgeryToken()%> <fieldset> <legend>Widget Omschrijving</legend> <div> <%= Html.LabelFor(Model => Model.Name) %> <%= Html.TextBoxFor(Model => Model.Name) %> <%= Html.ValidationMessageFor(Model => Model.Name) %> </div> </fieldset> <div> <input type="submit" value="Save" /> </div> <% } %> To make this all work I added also references to js files: <script src="../../Scripts/MicrosoftAjax.js" type="text/javascript"></script> <script src="../../Scripts/MicrosoftMvcAjax.js" type="text/javascript"></script> <script src="../../Scripts/MicrosoftMvcValidation.js" type="text/javascript"></script> <script src="../../Scripts/jquery-1.4.1.min.js" type="text/javascript"></script> Eventually it has to work, but it doesnt work 100%: It does validates with no page refresh after pressing the button. It also does "half" Client Side Validation. Only when you type some text into the textbox and then backspace the typed text. The Client Side Validation appears. But when I try this by tapping between controls there's no Client Side Validation. Do I miss some reference or something? (I use Asp.Net MVC 2 RTM)

• asp.net MVC RC1 RenderPartial ViewDataDictionary

  - by Mark79

  I'm trying to pass a ViewData object from a master page to a view user control using the ViewDataDictionary. The problem is the ViewDataDictionary is not returning any values in the view user control whichever way i try it. The sample code below is using an anonymous object just for demonstration although neither this method or passing a ViewData object works. Following is the RenderPartial helper method i'm trying to use: <% Html.RenderPartial("/Views/Project/Projects.ascx", ViewData.Eval("Projects"), new ViewDataDictionary(new { Test = "Mark" })); %> and in my view user control i do the following: <%= Html.Encode(ViewData["Test"]) %> Why does this not return anything? Thanks for your help. EDIT: I'm able to pass and access the stronlgy typed model without any problems. it's the ViewDataDictionary which i'm trying to use to pass say just a single value outside of the model..

• Rx Reactive extensions: Unit testing with FromAsyncPattern

  - by Andrew Anderson

  The Reactive Extensions have a sexy little hook to simplify calling async methods: var func = Observable.FromAsyncPattern<InType, OutType>( myWcfService.BeginDoStuff, myWcfService.EndDoStuff); func(inData).ObserveOnDispatcher().Subscribe(x => Foo(x)); I am using this in an WPF project, and it works great at runtime. Unfortunately, when trying to unit test methods that use this technique I am experiencing random failures. ~3 out of every five executions of a test that contain this code fails. Here is a sample test (implemented using a Rhino/unity auto-mocking container): [TestMethod()] public void SomeTest() { // arrange var container = GetAutoMockingContainer(); container.Resolve<IMyWcfServiceClient>() .Expect(x => x.BeginDoStuff(null, null, null)) .IgnoreArguments() .Do( new Func<Specification, AsyncCallback, object, IAsyncResult>((inData, asyncCallback, state) => { return new CompletedAsyncResult(asyncCallback, state); })); container.Resolve<IRepositoryServiceClient>() .Expect(x => x.EndRetrieveAttributeDefinitionsForSorting(null)) .IgnoreArguments() .Do( new Func<IAsyncResult, OutData>((ar) => { return someMockData; })); // act var target = CreateTestSubject(container); target.DoMethodThatInvokesService(); // Run the dispatcher for everything over background priority Dispatcher.CurrentDispatcher.Invoke(DispatcherPriority.Background, new Action(() => { })); // assert Assert.IsTrue(my operation ran as expected); } The problem that I see is that the code that I specified to run when the async action completed (in this case, Foo(x)), is never called. I can verify this by setting breakpoints in Foo and observing that they are never reached. Further, I can force a long delay after calling DoMethodThatInvokesService (which kicks off the async call), and the code is still never run. I do know that the lines of code invoking the Rx framework were called. Other things I've tried: I have attempted to modify the second last line according to the suggestions here: Reactive Extensions Rx - unit testing something with ObserveOnDispatcher No love. I have added .Take(1) to the Rx code as follows: func(inData).ObserveOnDispatcher().Take(1).Subscribe(x = Foo(x)); This improved my failure rate to something like 1 in 5, but they still occurred. I have rewritten the Rx code to use the plain jane Async pattern. This works, however my developer ego really would love to use Rx instead of boring old begin/end. In the end I do have a work around in hand (i.e. don't use Rx), however I feel that it is not ideal. If anyone has ran into this problem in the past and found a solution, I'd dearly love to hear it.

• Ajax call to wcf windows service over ssl (https)

  - by bpatrick100

  I have a windows service which exposes an endpoint over http. Again this is a windows service (not a web service hosted in iis). I then call methods from this endpoint, using javascript/ajax. Everything works perfectly, and this the code I'm using in my windows service to create the endpoint: //Create host object WebServiceHost webServiceHost = new WebServiceHost(svcHost.obj, new Uri("http://192.168.0.100:1213")); //Add Https Endpoint WebHttpBinding binding = new WebHttpBinding(); webServiceHost.AddServiceEndpoint(svcHost.serviceContract, binding, string.Empty); //Add MEX Behaivor and EndPoint ServiceMetadataBehavior metadataBehavior = new ServiceMetadataBehavior(); metadataBehavior.HttpGetEnabled = true; webServiceHost.Description.Behaviors.Add(metadataBehavior); webServiceHost.AddServiceEndpoint(ServiceMetadataBehavior.MexContractName, MetadataExchangeBindings.CreateMexHttpBinding(), "mex"); webServiceHost.Open(); Now, my goal is to get this same model working over SSL (https not http). So, I have followed the guidance of several msdn pages, like the following: http://msdn.microsoft.com/en-us/library/ms733791(VS.100).aspx I have used makecert.exe to create a test cert called "bpCertTest". I have then used netsh.exe to configure my port (1213) with the test cert I created, all with no problem. Then, I've modified the endpoint code in my windows service to be able to work over https as follows: //Create host object WebServiceHost webServiceHost = new WebServiceHost(svcHost.obj, new Uri("https://192.168.0.100:1213")); //Add Https Endpoint WebHttpBinding binding = new WebHttpBinding(); binding.Security.Mode = WebHttpSecurityMode.Transport; binding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Certificate; webServiceHost.AddServiceEndpoint(svcHost.serviceContract, binding, string.Empty); webServiceHost.Credentials.ServiceCertificate.SetCertificate("CN=bpCertTest", StoreLocation.LocalMachine, StoreName.My); //Add MEX Behaivor and EndPoint ServiceMetadataBehavior metadataBehavior = new ServiceMetadataBehavior(); metadataBehavior.HttpsGetEnabled = true; webServiceHost.Description.Behaviors.Add(metadataBehavior); webServiceHost.AddServiceEndpoint(ServiceMetadataBehavior.MexContractName, MetadataExchangeBindings.CreateMexHttpsBinding(), "mex"); webServiceHost.Open(); The service creates the endpoint successfully, recognizes my cert in the SetCertificate() call, and the service starts up and running with success. Now, the problem is my javascript/ajax call cannot communicate with the service over https. I simply get some generic commication error (12031). So, as a test, I changed the port I was calling in the javascript to some other random port, and I get the same error - which tells me that I'm obviously not even reaching my service over https. I'm at a complete loss at this point, I feel like everything is in place, and I just can't see what the problem is. If anyone has experience in this scenario, please provide your insight and/or solution! Thanks!

• Fiddler not sniffing SOAP traffic from ASP.NET website

  - by JohnIdol

  So far I've been successfully using fiddler to sniff web service traffic from both test fixtures, console apps and web projects. Today I noticed I am not able anymore to sniff that kind of traffic if I am running my web application (it's a ASP.NET website, hosted locally on IIS). I see all the local traffic but the web service traffic is just gone (the service is being hit as I do see the response debugging into the code). I am still able to successfully sniff soap requests and responses from test fixtures or console apps in the same solution (exact same environment). If it was a windows (I am on Win7) security update or the likes it would never work I guess (unless it affects only traffic routed through IIS). What should I be looking for that could cause the emergence this behavior? Any pointers appreciated!

• MVC2 Ajax Form does unwanted page refresh

  - by Kay

  Hi, I am pretty new to MVC. I have my first Ajax Form here: <div id="test"></div> <div id="MainChatMenu"> <% using (Ajax.BeginForm("SendMessage", "MainChat", new AjaxOptions { UpdateTargetId="test"})) { %> <input id="chatMessageText" type="text" maxlength="200" /> <input type="submit" value="Go"/> <% } %> Now, if I click the submit button, the page is reloading, goint to mysite/controller/action. I thought that the default behaviour of the Ajax.BeginForm was exactly not to do that? Where's my newbie mistake? My Controller is called correctly, but data passing also doesn't work. Probably because of the same mistake? Here's the code: public class MainChatController : Controller { [AcceptVerbs(HttpVerbs.Post)] public EmptyResult SendMessage(FormCollection formValues) { return new EmptyResult(); } }

• iPhone SDK "loading" on Titanium Developer

  - by raulriera

  Hi, I have tried this question on the site of Titanium and several tweets to their account, but they either ignore me or refuse to answer. I want to start using their framework, but for some reason the iPhone SDK is always "loading" when in the "TEST & PACKAGE" tab. Have you guys found a fix for this? I have: Snow Leopard 10.6.3 Titanium Developer 1.2.1 iPhone SDK 3.2 All the certificates "blah blah" from Apple because I am able to test and deploy apps on my device using XCode. Help please :)
