• Issues Deploying ROOT Context in Tomcat6

  - by Josh K

  I'm working on getting an application deployed to the ROOT ("/") context in my Tomcat 6 instance. Here's what has been done: Defined another virtual host (domain.com) Created the respective folder (/etc/tomcat6/Catalina/domain.com) Set it to auto deploy WAR's Set appBase to CATALINA_BASE/domainapps and created respective folder Copied manager.xml from localhost to domain.com. Now I'm trying to deploy into the ROOT context by uploading a ROOT.war to CATALINA_BASE/domainapps. This isn't working. I don't get any exceptions thrown, but the stock ROOT page ("It works !") stays up. I have successfully deployed it into another context (by uploading domainapp.war and viewing at /domainapp), but not ROOT. Re-reading the Virtual Host setup it makes reference to CATALINA_HOME and CATALINA_BASE. My CATALINA_HOME is at /usr/share/tomcat6/domainapp while CATALINA_BASE is /var/lib/tomcat6. Which should I be using for what? Currently haven't touched CATALINA_HOME but will try messing with a few things there. A better question might be what is the generally accepted flow taken to setup a new Tomcat instance and deploy an application to the root context.

• standard way to perform a clean shutdown with Boost.Asio

  - by Timothy003

  I'm writing a cross-platform server program in C++ using Boost.Asio. Following the HTTP Server example on this page, I'd like to handle a user termination request without using implementation-specific APIs. I've initially attempted to use the standard C signal library, but have been unable to find a design pattern suitable for Asio. The Windows example's design seems to resemble the signal library closest, but there's a race condition where the console ctrl handler could be called after the server object has been destroyed. I'm trying to avoid race conditions that cause undefined behavior as specified by the C++ standard. Is there a standard (correct) way to stop the server? So far: #include <csignal> #include <functional> #include <boost/asio.hpp> using std::signal; using boost::asio::io_service; extern "C" { static void handle_signal(int); } namespace { std::function<void ()> sighandler; } void handle_signal(int) { sighandler(); } int main() { io_service s; sighandler = std::bind(&io_service::stop, &s); auto res = signal(SIGINT, &handle_signal); // race condition? SIGINT raised before I could set ignore back if (res == SIG_IGN) signal(SIGINT, SIG_IGN); res = signal(SIGTERM, &handle_signal); // race condition? SIGTERM raised before I could set ignore back if (res == SIG_IGN) signal(SIGTERM, SIG_IGN); s.run(); // reset signals signal(SIGTERM, SIG_DFL); signal(SIGINT, SIG_DFL); // is it defined whether handle_signal can still be in execution at this // point? sighandler = nullptr; }

• Can I use pdb files to step through a 3rd party assembly?

  - by Pure.Krome

  Hi folks, my friend has made a really helpful class library which I use all the time. I usually use Reflector to see what his code does. What I really wanted to do was to step through his code while I'm debugging. So he gave me his .pdb file. Foo.dll (release configuration, compile) Foo.pdb Now, I'm not sure how I can get it to auto break into his code when it throws an exception (his code, at various points, thorws exceptions .. like A first chance exception of type 'System.Web.HttpException' occurred in Foo.dll ... Can I do this? Do i need to setup something with the Symbol Server settings in Visual Studio ? Do i need to get the dll compiled into Debug Configuration and be passed the .dll and .pdb files? Or (and i'm really afraid of this one) .. do i need to have both the .dll, .pdb AND his source code ... I also had a look at this previous SO question, but it sorta didn't help (but proof I've tried to search before asking a question). Can someone help me please?

• Oracle why does creating trigger fail when there is a field called timestamp?

  - by Omar Kooheji

  I've just wasted the past two hours of my life trying to create a table with an auto incrementing primary key bases on this tutorial, The tutorial is great the issue I've been encountering is that the Create Target fails if I have a column which is a timestamp and a table that is called timestamp in the same table... Why doesn't oracle flag this as being an issue when I create the table? Here is the Sequence of commands I enter: Creating the Table: CREATE TABLE myTable (id NUMBER PRIMARY KEY, field1 TIMESTAMP(6), timeStamp NUMBER, ); Creating the Sequence: CREATE SEQUENCE test_sequence START WITH 1 INCREMENT BY 1; Creating the trigger: CREATE OR REPLACE TRIGGER test_trigger BEFORE INSERT ON myTable REFERENCING NEW AS NEW FOR EACH ROW BEGIN SELECT test_sequence.nextval INTO :NEW.ID FROM dual; END; / Here is the error message I get: ORA-06552: PL/SQL: Compilation unit analysis terminated ORA-06553: PLS-320: the declaration of the type of this expression is incomplete or malformed Any combination that does not have the two lines with a the word "timestamp" in them works fine. I would have thought the syntax would be enough to differentiate between the keyword and a column name. As I've said I don't understand why the table is created fine but oracle falls over when I try to create the trigger... CLARIFICATION I know that the issue is that there is a column called timestamp which may or may not be a keyword. MY issue is why it barfed when I tried to create a trigger and not when I created the table, I would have at least expected a warning. That said having used Oracle for a few hours, it seems a lot less verbose in it's error reporting, Maybe just because I'm using the express version though. If this is a bug in Oracle how would one who doesn't have a support contract go about reporting it? I'm just playing around with the express version because I have to migrate some code from MySQL to Oracle.

• What is the best way to use Guice and JMock together?

  - by Yishai

  I have started using Guice to do some dependency injection on a project, primarily because I need to inject mocks (using JMock currently) a layer away from the unit test, which makes manual injection very awkward. My question is what is the best approach for introducing a mock? What I currently have is to make a new module in the unit test that satisfies the dependencies and bind them with a provider that looks like this: public class JMockProvider<T> implements Provider<T> { private T mock; public JMockProvider(T mock) { this.mock = mock; } public T get() { return mock; } } Passing the mock in the constructor, so a JMock setup might look like this: final CommunicationQueue queue = context.mock(CommunicationQueue.class); final TransactionRollBack trans = context.mock(TransactionRollBack.class); Injector injector = Guice.createInjector(new AbstractModule() { @Override protected void configure() { bind(CommunicationQueue.class).toProvider(new JMockProvider<QuickBooksCommunicationQueue>(queue)); bind(TransactionRollBack.class).toProvider(new JMockProvider<TransactionRollBack>(trans)); } }); context.checking(new Expectations() {{ oneOf(queue).retrieve(with(any(int.class))); will(returnValue(null)); never(trans); }}); injector.getInstance(RunResponse.class).processResponseImpl(-1); Is there a better way? I know that AtUnit attempts to address this problem, although I'm missing how it auto-magically injects a mock that was created locally like the above, but I'm looking for either a compelling reason why AtUnit is the right answer here (other than its ability to change DI and mocking frameworks around without changing tests) or if there is a better solution to doing it by hand.

• How to insert records in master/detail relationship

  - by croceldon

  I have two tables: OutputPackages (master) |PackageID| OutputItems (detail) |ItemID|PackageID| OutputItems has an index called 'idxPackage' set on the PackageID column. ItemID is set to auto increment. Here's the code I'm using to insert masters/details into these tables: //fill packages table for i := 1 to 10 do begin Package := TfPackage(dlgSummary.fcPackageForms.Forms[i]); if Package.PackageLoaded then begin with tblOutputPackages do begin Insert; FieldByName('PackageID').AsInteger := Package.ourNum; FieldByName('Description').AsString := Package.Title; FieldByName('Total').AsCurrency := Package.Total; Post; end; //fill items table for ii := 1 to 10 do begin Item := TfPackagedItemEdit(Package.fc.Forms[ii]); if Item.Activated then begin with tblOutputItems do begin Append; FieldByName('PackageID').AsInteger := Package.ourNum; FieldByName('Description').AsString := Item.Description; FieldByName('Comment').AsString := Item.Comment; FieldByName('Price').AsCurrency := Item.Price; Post; //this causes the primary key exception end; end; end; end; This works fine as long as I don't mess with the MasterSource/MasterFields properties in the IDE. But once I set it, and run this code I get an error that says I've got a duplicate primary key 'ItemID'. I'm not sure what's going on - this is my first foray into master/detail, so something may be setup wrong. I'm using ComponentAce's Absolute Database for this project. How can I get this to insert properly? Update Ok, I removed the primary key restraint in my db, and I see that for some reason, the autoincrement feature of the OutputItems table isn't working like I expected. Here's how the OutputItems table looks after running the above code: ItemID|PackageID| 1 |1 | 1 |1 | 2 |2 | 2 |2 | I still don't see why all the ItemID values aren't unique.... Any ideas?

• Error: "Cannot simultaneously fetch multiple bags" when calling Configuration.BuildSessionFactory();

  - by Nick Meldrum

  We are getting this error after upgrading to NHibernate 2.1. [QueryException: Cannot simultaneously fetch multiple bags.] NHibernate.Loader.BasicLoader.PostInstantiate() +418 NHibernate.Loader.Entity.EntityLoader..ctor(IOuterJoinLoadable persister, String[] uniqueKey, IType uniqueKeyType, Int32 batchSize, LockMode lockMode, ISessionFactoryImplementor factory, IDictionary`2 enabledFilters) +123 NHibernate.Loader.Entity.BatchingEntityLoader.CreateBatchingEntityLoader(IOuterJoinLoadable persister, Int32 maxBatchSize, LockMode lockMode, ISessionFactoryImplementor factory, IDictionary`2 enabledFilters) +263 NHibernate.Persister.Entity.AbstractEntityPersister.CreateEntityLoader(LockMode lockMode, IDictionary`2 enabledFilters) +26 NHibernate.Persister.Entity.AbstractEntityPersister.CreateLoaders() +57 NHibernate.Persister.Entity.AbstractEntityPersister.PostInstantiate() +1244 NHibernate.Persister.Entity.SingleTableEntityPersister.PostInstantiate() +18 NHibernate.Impl.SessionFactoryImpl..ctor(Configuration cfg, IMapping mapping, Settings settings, EventListeners listeners) +3261 NHibernate.Cfg.Configuration.BuildSessionFactory() +87 Without stepping into the NHibernate source, it doesn't look like I can see which mapping is creating the issue. It's a very old application with a load of mappings files, lots of mappings have one-to-many bags in them, all lazy instantiated. For example: <bag name="Ownership" lazy="true" cascade="all" inverse="true" outer-join="auto" where="fkOwnershipStatusID!=6"> <key column="fkStakeHolderID"/> <one-to-many class="StakeholderLib.Ownership,StakeholderLib" /> </bag> maps to: public virtual IList Ownership { get { if (ownership == null) ownership = new ArrayList(); return ownership; } set { ownership = value; } } Has anyone seen this error before when upgrading to NHibernate 2.1?

• Grails Deployment - Fastest way to get deployed?

  - by gav

  Hi All, If anyone has or is running a Grails application on their server I would appreciate some details on where to go after creating the WAR. Background I chose grails because with Google App Engine and the App Engine Plugin deployment should have been trivial. This issue is that there is a bug which makes any application pretty much unusable, I wish this had been more prominent so I didn't have to get to the point of seeing the error myself before I was aware of it. The next option was EC2 and the Cloud Tools plugin, it seems Cloud Tools worked with grails 1.0 but doesn't work with the current 1.2.1 due to issues getting the JAR dependencies. It also seems that Cloud Tools has been succeeded by Cloud Foundry which is in beta, will cost extra money and has limited places (I signed up but haven't got an e-mail). Question My application is painfully trivial, it has a small load, small data requirements and doesn't need to scale past 5 users. How can I deploy my grails app as quickly and painlessly as possible? Specifically: Are there any hosting companies that have tomcat installed on their servers out of the box that I can sign up to and use that will just work? Do you know of any simple tutorials for getting a grails application deployed to EC2 without Cloud Tools? Thanks in advance, Gav Side-note: I picked grails because of good advice from SO, it should have been a very short time from development to deployed product except the tools for auto-deployment aren't that mature and I've never configured a server before.

• Best strategy for synching data in iPhone app

  - by iamj4de

  I am working on a regular iPhone app which pulls data from a server (XML, JSON, etc...), and I'm wondering what is the best way to implement synching data. Criteria are speed (less network data exchange), robustness (data recovery in case update fails), offline access and flexibility (adaptable when the structure of the database changes slightly, like a new column). I know it varies from app to app, but can you guys share some of your strategy/experience? For me, I'm thinking of something like this: 1) Store Last Modified Date in iPhone 2) Upon launching, send a message like getNewData.php?lastModifiedDate=... 3) Server will process and send back only modified data from last time. 4) This data is formatted as so: <+><data id="..."></data></+> // add this to SQLite/CoreData <-><data id="..."></data></-> // remove this <%><data id="..."><attribute>newValue</attribute></data></%> // new modified value I don't want to make <+, <-, <%... for each attribute as well, because it would be too complicated, so probably when receive a <% field, I would just remove the data with the specified id and then add it again (assuming id here is not some automatically auto-incremented field). 5) Once everything is downloaded and updated, I will update the Last Modified Date field. The main problem with this strategy is: If the network goes down when I am updating something = the Last Modified Date is not yet updated = next time I relaunch the app, I will have to go through the same thing again. Not to mention potential inconsistent data. If I use a temporary table for update and make the whole thing atomic, it would work, but then again, if the update is too long (lots of data change), the user has to wait a long time until new data is available. Should I use Last-Modified-Date for each of the data field and update data gradually?

• Basic compile issue with QT4

  - by Cobus Kruger

  I've been trying to get a dead simple listing from a university textbook to compile with the newest QT SDK for Windows I downloaded last night. After struggling through the regular nonsense (no make.bat, need to manually add environment variables and so on) I am finally at the point where I can build. But only one of the two libraries seem to work. The .pro file I use is dead simple: SUBDIRS += utils \ dataobjects TEMPLATE = subdirs In each of these two subfolders I have the source for a library. Running QMAKE generates a makefile and running Make runs through all the preliminaries and then fails on the g++ call: g++ -enable-stdcall-fixup -Wl,-enable-auto-import -Wl,-enable-runtime-pseudo-reloc --out-implib,libdataobjects.a -shared -mthreads -Wl -Wl,--out-implib,c:\Users\Cobus\workspace\lib\libdataobjects.a -o ..\..\lib\dataobjects.dll object_script.dataobjects.Debug -L"c:\Users\Cobus\Portab~1\Qt\2010.02.1\qt\lib" -LC:\Users\Cobus\workspace\lib -lutils -lQtXmld4 -lQtGuid4 -lQtCored4 c:/users/cobus/portab~1/qt/2010.02.1/mingw/bin/../lib/gcc/mingw32/4.4.0/../../../../mingw32/bin/ld.exe: cannot find -lutils The problem seems to be right near the end of the command line, where -lutils is added, indicating that there is a library by the name of utils. While I would have expected to see that, you'll notice the library names after --out include lib in the name, so they become libutils and libdataobjects. I have tried to figure out why this is happening, to no avail. Anyone have an idea what's going on?

• .NET proxy detection

  - by Ziplin

  I am having an issue with .NET detecting the proxy settings configured through internet explorer. I'm writing a client application that supports proxies, and to test I set up an array of 9 squid servers to support various authentication methods for HTTP and HTTPs. I have a script that updates IE to whichever configuration I choose (which proxy, detection via "Auto", PAC, or hardcode). I have tried the 3 methods below to detect the IE configuration through .NET. On occassion I notice that .NET picks up the wrong set of proxy servers. IE has the correct settings, and if I browse the web with IE, I can see I am hitting the correct servers via wireshark. WebRequest.GetSystemWebProxy().GetProxy(destination); GlobalProxySelection.Select.GetProxy(destination); WebRequest.DefaultWebProxy Here are the following tips I have: My script sets a PAC file on a webserver, and updates the configuration in IE, then clears IE's cache .NET seems to get "stuck" on a certain proxy configuration, and I have to set another configuration for .NET to realize there was a change. Occasionally it seems to pick some random set of servers (I'm sure they're not random, just a set of servers I used once and are in some cached PAC file or something). As in, I will check the proxy for the destination "https://www.secure.com" and I may have IE configured for and thus expect to get "http://squidserver:18" and instead it will return "http://squidserver:28" (port 18 runs NTLM, 28 runs without authentication). All the squid servers work. This does not appear to be an issue on XP, only Vista, 2003, and windows 7. Hardcoding the proxy servers in IE ALWAYS works Time always solves the issue - if I leave the computer for about 20 or 30 minutes and come back, .NET picks up the correct proxy settings, as if a cached PAC script expired.

• How can I create an automatically generated alteranate table row color ?

  - by UXdesigner

  Good day, I've been trying to make this CSS code work: table.mytable { margin: 0; padding: 0; border: 0; font-size: 0.8em; border-collapse: collapse; } table.mytable td, table.mytable th { width: auto; padding: 2px 4px; vertical-align: top; } table.mytable th { color: #fff; background:url(images/header-bg.gif); text-align: left; } table.mytable tr.alternateColor { background-color:#E9F3FC; } well, it works, if I do write it manually. But as the tables are going to be generated thru asp.NET (Aspx) , which is not manually created- I'd like my table to generate the alternate rows. I've been trying to make this work with Javascript, but I can't figure it out and I believe this is a good resource site. I've been using a manual table with Adobe Dreamweaver cs4 as a test, but I have to put the class of "alternatecolors" in order to make them appear, and I can't do this normally.: Question is , can someone provide me a good Javascript that I would put in the header of the file, and actually help me out to make this work ? I think I'm burned...or maybe I can't see what others see quickly due to the amount of time I've spent. I just tried posting the code of my table here, but I couldn't get it well formatted and I got to run... I'm not using an 'id' on this table, but the class is 'mytable'. Thank you so much for your good help.

  I created in code a database and two tables: static final String dbName="graficeCirculatie"; static final String ruteTable="Rute"; static final String colRuteId="RutaID"; static final String colRuta="Ruta"; static final String statiaTable="Statia"; static final String colStatiaID="StatiaID"; static final String colIdRuta="IdRuta"; static final String colStatia="Statia"; public DatabaseHelper(Context context) { super(context, dbName, null,33); } public void onCreate(SQLiteDatabase db) { // TODO Auto-generated method stub db.execSQL("CREATE TABLE " + statiaTable + " (" + colStatiaID + " INTEGER PRIMARY KEY , " + colIdRuta + " INTEGER, " + colStatia + " TEXT)"); db.execSQL("CREATE TABLE " + ruteTable + "(" + colRuteId + " INTEGER PRIMARY KEY AUTOINCREMENT, " + colRuta + " TEXT);"); InsertDepts(db); } void InsertDepts(SQLiteDatabase db) { ContentValues cv = new ContentValues(); cv.put(colRuteId, 1); cv.put(colRuta, "Expres8"); db.insert(ruteTable, colRuteId, cv); cv.put(colRuteId, 2); cv.put(colRuta, "Expres2"); db.insert(ruteTable, colRuteId, cv); cv.put(colRuteId, 3); cv.put(colRuta, "Expres3"); db.insert(ruteTable, colRuteId, cv); } Now I want to see tables inputs from command line. I try in this way: C:\Program Files\Android\android-sdk\tools sqlite3 SQLite version 3.7.4 Enter ".help" for instructions Enter SQL statements terminated with a ";" sqlite sqlite3 graficeCirculatie ... select * from ruteTable; And I got an error: Error: near "squlite3": syntax error. Can someone help me?

• Delphi: how to lock dfm-s to not change...?

  - by durumdara

  Hi! We used Delphi 6 long times ago. Our problem, that Delphi have two problems with DFMs: 1.) When some linked resource (like DataSet) will removed, Delphi many times forget to ask you that "some of the resources are linked, you need to redirect...". This happens, when the actual form is not added to the project, or it is not opened. 2.) When we only open the DFM, and only see some thing, may we change it (active TabSheet, form position). Then Delphi auto save the form - and sometimes it drops the links. Another problem with this that we used SVN, and SVN detect these changes... We thought that we change DFM files to read only, but this can prevent the usage of SVN too... So somebody please help us: have the Delphi some extension (like gexpert) that can lock the DFMs to avoid changes, and some other tool to see that dataset is used in other forms or not? Thanks for your help: dd

• What's the difference between the input type "text" and "password" in an html form?

  - by Domingo

  Hi everybody, this question might seem stupid, but here's the situation: I'm trying to create an auto login page for my mail using jquery's post request, but it's not working, it works with all other pages except with webmail. So, trying to figure out what was wrong, I recreated the login form, here's the code: <form id="form1" name="form1" method="post" action="https://login.hostmonster.com/"> <label>User <input type="text" name="login" id="user" /> </label> <label>Pass <input name="password" type="password" id="pass" /> </label> <input name="doLogin" type="submit" id="doLogin" value="Login"> </form> The strange thing is when you change the input type of pass to text, the form doesn't work! I can't figure out why. Anyway, if you can tell me what's the real difference between the input type text and password (and not what it says everywhere on the net that the only difference is that when you type stars appear instead of characters) I would appreciate it. Also, do you think this is affecting my jquery's post? Here's the code for it: $j.post('https://login.hostmonster.com/', { login: '[email protected]', password: 'xxx' }, function(data, text){ if (text=='success') { alert('Success '+data); } else { alert('Failed'); } }); Thanks a lot! Regards, D

• Demangling typeclass functions in GHC profiler output

  - by Paul Kuliniewicz

  When profiling a Haskell program written in GHC, the names of typeclass functions are mangled in the .prof file to distinguish one instance's implementations of them from another. How can I demangle these names to find out which type's instance it is? For example, suppose I have the following program, where types Fast and Slow both implement Show: import Data.List (foldl') sum' = foldl' (+) 0 data Fast = Fast instance Show Fast where show _ = show $ sum' [1 .. 10] data Slow = Slow instance Show Slow where show _ = show $ sum' [1 .. 100000000] main = putStrLn (show Fast ++ show Slow) I compile with -prof -auto-all -caf-all and run with +RTS -p. In the .prof file that gets generated, I see that the top cost centers are: COST CENTRE MODULE %time %alloc show_an9 Main 71.0 83.3 sum' Main 29.0 16.7 And in the tree, I likewise see (omitting irrelevant lines): individual inherited COST CENTRE MODULE no. entries %time %alloc %time %alloc main Main 232 1 0.0 0.0 100.0 100.0 show_an9 Main 235 1 71.0 83.3 100.0 100.0 sum' Main 236 0 29.0 16.7 29.0 16.7 show_anx Main 233 1 0.0 0.0 0.0 0.0 How do I figure out that show_an9 is Slow's implementation of show and not Fast's?

• Common lisp, CFFI, and instantiating c structs

  - by andrew

  Hi, I've been on google for about, oh, 3 hours looking for a solution to this "problem." I'm trying to figure out how to instantiate a C structure in lisp using CFFI. I have a struct in c: struct cpVect{cpFloat x,y;} Simple right? I have auto-generated CFFI bindings (swig, I think) to this struct: (cffi:defcstruct #.(chipmunk-lispify "cpVect" 'classname) (#.(chipmunk-lispify "x" 'slotname) :double) (#.(chipmunk-lispify "y" 'slotname) :double)) This generates a struct "VECT" with slots :X and :Y, which foreign-slot-names confirms (please note that I neither generated the bindings or programmed the C library (chipmunk physics), but the actual functions are being called from lisp just fine). I've searched far and wide, and maybe I've seen it 100 times and glossed over it, but I cannot figure out how to create a instance of cpVect in lisp to use in other functions. Note the function: cpShape *cpPolyShapeNew(cpBody *body, int numVerts, cpVect *verts, cpVect offset) Takes not only a cpVect, but also a pointer to a set of cpVects, which brings me to my second question: how do I create a pointer to a set of structs? I've been to http://common-lisp.net/project/cffi/manual/html_node/defcstruct.html and tried the code, but get "Error: Unbound variable: PTR" (I'm in Clozure CL), not to mention that looks to only return a pointer, not an instance. I'm new to lisp, been going pretty strong so far, but this is the first real problem I've hit that I can't figure out. Thanks!

• Visual Studio 2010 Professional - Problem Unit-Testing Web Services

  - by Ben

  Have created a very simple Web Service (asmx) in Visual Studio 2010 Professional, and am trying to use the auto-generated unit test cases. I get something that seems quite familiar on this site: The web site could not be configured correctly; getting ASP.NET process information failed. Requesting http://localhost:81/zfp/VSEnterpriseHelper.axd return an error: The remote server returned an error: (500) Internal Server Error. http://stackoverflow.com/questions/260432/500-error-running-visual-studio-asp-net-unit-test I have tried: 1. Running the tests on IIS rather than ASP.NET Development Server 2. Adding and then removing the XML fragment to my Web Service's .config file 3. Giving the MACHINE\ASPNET account Full control to the local folder My current questions: 1. Why am I being bothered with this instrumentation / code coverage DLL, when this doesn't seem to be something that ships with Visual Studio 2010 Professional? Is there any way I can turn it off? 2. I'm placing the node under in Web.config - is that the correct node? 3. Is it possible to bind to a web service without using the webby test attributes? I've seen other people advising making the Web Service as light-weight as possible. I'm trying to call it with jQuery / AJAX / JSON, so being able to debug the actual web service would be really helpful. Best wishes, Ben
