• Unable to execute a function usnig reflection

  - by Steven

  hi, i am developing a eclipse plugin . In this plugin i am using reflection to execute a function in a class present in another project which is a hibernate project.Whenever the invoke is used i.e mymethod.invoke(myobj); it is giving this exception java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:37) at java.lang.reflect.Method.invoke(Method.java:599) at packagesearch.DummyExecution.execution(DummyExecution.java:154) at packagesearch.HelloWorldAction.run(HelloWorldAction.java:48) at org.eclipse.ui.internal.PluginAction.runWithEvent(PluginAction.java:251) at org.eclipse.ui.internal.WWinPluginAction.runWithEvent(WWinPluginAction.java:229) at org.eclipse.jface.action.ActionContributionItem.handleWidgetSelection(ActionContributionItem.java:583) at org.eclipse.jface.action.ActionContributionItem.access$2(ActionContributionItem.java:500) at org.eclipse.jface.action.ActionContributionItem$6.handleEvent(ActionContributionItem.java:452) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:84) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:1003) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3823) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3422) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2384) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2348) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2200) at org.eclipse.ui.internal.Workbench$5.run(Workbench.java:495) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:288) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:490) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:113) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:193) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:110) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:79) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:386) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:179) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:37) at java.lang.reflect.Method.invoke(Method.java:599) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:549) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:504) at org.eclipse.equinox.launcher.Main.run(Main.java:1236) at org.eclipse.equinox.launcher.Main.main(Main.java:1212) Caused by: java.lang.NoClassDefFoundError: org.dom4j.DocumentException at java.lang.J9VMInternals.verifyImpl(Native Method) at java.lang.J9VMInternals.verify(J9VMInternals.java:72) at java.lang.J9VMInternals.initialize(J9VMInternals.java:134) at test.Example.demo1(Example.java:38) ... 36 more Caused by: java.lang.ClassNotFoundException: org.dom4j.DocumentException at java.net.URLClassLoader.findClass(URLClassLoader.java:419) at java.lang.ClassLoader.loadClass(ClassLoader.java:643) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:345) at java.lang.ClassLoader.loadClass(ClassLoader.java:609) ... 40 more what is the exact problem . i have used loader to load the class.Help

• Asp.net MVC and MOSS 2010 integration

  - by Robert Koritnik

  Just a sidenote: I'm not sure whether I should post this to serverfault as well, because some MOSS admin may have some info for me as well? A bit of explanation first (without Asp.net MVC) Is it possible to integrate the two? Is it possible to write an application that would share at least credential information with MOSS? I have to write a MOSS application that has to do with these technologies: MOSS 2010 Personal client certificates authentication (most probably on USB keys) Active Directory Federation Services Separate SQL DB that would serve application specific data (separate as not being part of MOSS DB) How should it work? Users should authenticate using personal certificates into MOSS 2010 There would be a certain part of MOSS that would be related to my custom application This application should only authorize certain users via AD FS - I guess these users should have a certain security claim attached to them This application should manage users (that have access to this app) with additional (app specific) security claims related to this application (as additional application level authorization rights for individual application parts) This application should use custom SQL 2008 DB heavily with its own data This application should have the possibility to integrate with external systems as well (Exchange for instance to inject calendar entries, ERP systems etc) This application should be able to export its data (from its DB) to files. I don't know if it's possible, but it would be nice if the app could add these files to MOSS and attach authorization info to them so only users with sufficient rights would be able to view/open these files. Why Asp.net MVC then? I'm very well versed in Asp.net MVC (also with the latest version) and I haven't done anything on Sharepoint since version 2003 (which doesn't do me no good or prepare me for the latest version in any way shape or form). This project will most probably be a death march project so I would rather write my application as a UI rich Asp.net MVC application and somehow integrate it into MOSS. But not only via a link, because I would like to at least share credentials, so users wouldn't need to re-login when accessing my app. Using Asp.net MVC I would at least have the possibility to finish on time or be less death marching. Is this at all possible? Questions Is it possible to integrate Asp.net MVC into MOSS as described above? If integration is not possible, would it be possible to create a completely MOSS based application that would work as described? Which parts of MOSS 2010 should I use to accomplish what I need?

• I need help with this ogre dependent header (Qgears)

  - by commodore

  I'm 2 errors away from compiling Qgears. (Hacked Version of the Final Fantasy VII Engine) I've messed with the preprocessors to load the actual location of the ogre header files. Here are the errors: ||=== qgears, Debug ===| /home/cj/Desktop/qgears/trunk/project/linux/src/core/TextManager.h|48|error: invalid use of ‘::’| /home/cj/Desktop/qgears/trunk/project/linux/src/core/TextManager.h|48|error: expected ‘;’ before ‘m_LanguageRoot’| ||=== Build finished: 2 errors, 0 warnings ===| Here's the header file: // $Id$ #ifndef TEXT_MANAGER_h #define TEXT_MANAGER_h #include <OGRE/OgreString.h> #include <OGRE/OgreUTFString.h> #include <map> struct TextData { TextData(): text(""), width(0), height(0) { } Ogre::String name; Ogre::UTFString text; int width; int height; }; typedef std::vector<TextData> TextDataVector; class TextManager { public: TextManager(void); virtual ~TextManager(void); void SetLanguageRoot(const Ogre::String& root); void LoadTexts(const Ogre::String& file_name); void UnloadTexts(const Ogre::String& file_name); const TextData GetText(const Ogre::String& name); private: struct TextBlock { Ogre::String block_name; std::vector<TextData> text; } Ogre::String m_LanguageRoot; // Line #48 std::list<TextBlock> m_Texts; }; extern TextManager* g_TextManager; #endif // TEXT_MANAGER_h The only header file that's in include that's not a ogre header file is "map". If it helps, I'm using the Code::Blocks IDE/GCC Compiler in GNU/Linux. (Arch) I'm not sure even if I get this header fixed, I think I'll have build errors latter, but it's worth a shot. Edit: I added the semicolon and I have one more error in the header file: error: expected unqualified-id before ‘{’ token

• Convincing Management to use WCF

  - by Kyle Rozendo

  Hi All, I asked another question, stating that the I am unable to use WCF in a new Web Service project and have come to see that it seems to be the technology to use in regards to extensibility and security. My question is a simple one: How can I persuade management (and developers for that matter) to move over to using WCF as opposed to other web service technologies (ASMX/CFC)? They won't be concerned with a comparison between the types (especially with regard to ASMX), simply what there is to gain. Thanks for your time, Kyle

  Hello, I am new to repositories and am currently looking around to find the best possible option. I need something that can handle multiple versions of our website, and allow multiple collaborators to all push to the repo together. Our current project is built in PHP, and we have a MySQL database. I am short on funding and need the best option for our money. I have limited ssh access to our server, however I have little to no experience working with repositories. Thanks, Mike

• Does my fat-client application belong in the MVC pattern?

  - by boatingcow

  The web-based application I’m currently working on is growing arms and legs! It’s basically an administration system which helps users to keep track of bookings, user accounts, invoicing etc. It can also be accessed via a couple of different websites using a fairly crude API. The fat-client design loosely follows the MVC pattern (or perhaps MVP) with a php/MySQL backend, Front Controller, several dissimilar Page Controllers, a liberal smattering of object-oriented and procedural Models, a confusing bunch of Views and templates, some JavaScripts, CSS files and Flash objects. The programmer in me is a big fan of the principle of “Separation of Concerns” and on that note, I’m currently trying to figure out the best way to separate and combine the various concerns as the project grows and more people contribute to it. The problem we’re facing is that although JavaScript (or Flash with ActionScript) is normally written with the template, hence part of the View and decoupled from the Controller and Model, we find that it actually encompasses the entire MVC pattern... Swap an image with an onmouseover event - that’s Behaviour. Render a datagrid - we’re manipulating the View. Send the result of reordering a list via AJAX - now we’re in Control. Check a form field to see if an email address is in a valid format - we’re consulting the Model. Is it wise to let the database people write up the validation Model with jQuery? Can the php programmers write the necessary Control structures in JavaScript? Can the web designers really write a functional AJAX form for their View? Should there be a JavaScript overlord for every project? If the MVC pattern could be applied to the people instead of the code, we would end up with this: Model - the database boffins - “SELECT * FROM mind WHERE interested IS NULL” Control - pesky programmers - “class Something extends NothingAbstractClass{…}” View - traditionally the domain of the graphic/web designer - “” …and a new layer: Behaviour - interaction and feedback designer - “CSS3 is the new black…” So, we’re refactoring and I’d like to stick to best practice design, but I’m not sure how to proceed. I don’t want to reinvent the wheel, so would anyone have any hints or tips as to what pattern I should be looking at or any code samples from someone who’s already done the dirty work? As the programmer guy, how can I rewrite the app for backend and front end whilst keeping the two separate? And before you ask, yes I’ve looked at Zend, CodeIgnitor, Symfony, etc., and no, they don’t seem to cross the boundary between server logic and client logic!

• How to Practice Unix Programming in C?

  - by danben

  After five years of professional Java (and to a lesser extent, Python) programming and slowly feeling my CS education slip away, I decided I wanted to broaden my horizons / general usefulness to the world and do something that feels more (to me) like I really have an influence over the machine. I chose to learn C and Unix programming since I feel like that is where many of the most interesting problems are. My end goal is to be able to do this professionally, if for no other reason than the fact that I have to spend 40-50 hours per week on work that pays the bills, so it may as well also be the type of coding I want to get better at. Of course, you don't get hired to do things you haven't dont before, so for now I am ramping up on my own. To this end, I started with K&R, which was a great resource in part due to the exercises spread throughout each chapter. After that I moved on to Computer Systems: A Programmer's Perspective, followed by ten chapters of Advanced Programming in the Unix Environment. When I am done with this book, I will read Unix Network Programming. What I'm missing in the Stevens books is the lack of programming problems; they mainly document functionality and provide examples, with a few end-of-chapter questions following. I feel that I would benefit much more from being challenged to use the knowledge in each chapter ala K&R. I could write some test program for each function, but this is a less desirable method as (1) I would probably be less motivated than if I were rising to some external challenge, and (2) I will naturally only think to use the function in the ways that have already occurred to me. So, I'd like to get some recommendations on how to practice. Obviously, my first choice would be to find some resource that has Unix programming challenges. I have also considered finding and attempting to contribute to some open source C project, but this is a bit daunting as there would be some overhead in learning to use the software, then learning the codebase. The only open-source C project I can think of that I use regularly is Python, and I'm not sure how easy that would be to get started on. That said, I'm open to all kinds of suggestions as there are likely things I haven't even thought of.
