Windows Phone period task, function not executing

- by Special K.

I'm trying to execute a code (to parse an XML to be more precisely, and after that I'll toast message the user with some new info's), but the class function AccDetailsDownloaded is not executed (is simply skipped), also the memory usage is ~2mb out of 6, here is my code: if (task is PeriodicTask) { getData(); } else { getData(); } // If debugging is enabled, launch the agent again in one minute. #if DEBUG_AGENT ScheduledActionService.LaunchForTest(task.Name, TimeSpan.FromSeconds(60)); #endif // Call NotifyComplete to let the system know the agent is done working. NotifyComplete(); } public void getData() { var settings = IsolatedStorageSettings.ApplicationSettings; string url = "http://example.com/example.xml"; if (!System.Net.NetworkInformation.NetworkInterface.GetIsNetworkAvailable()) { MessageBox.Show("No network connection available!"); return; } // start loading XML-data WebClient downloader = new WebClient(); Uri uri = new Uri(url, UriKind.Absolute); downloader.DownloadStringCompleted += new DownloadStringCompletedEventHandler(AccDetailsDownloaded); downloader.DownloadStringAsync(uri); string toastTitle = ""; toastTitle = "Periodic "; string toastMessage = "Mem usage: " + DeviceStatus.ApplicationPeakMemoryUsage + "/" + DeviceStatus.ApplicationMemoryUsageLimit; // Launch a toast to show that the agent is running. // The toast will not be shown if the foreground application is running.

What is the MSBuild equivalent to ant's -project-help?

- by Jeremy Stein

I come from an ant background, and I'm starting to use msbuild. I want to create a .proj file with targets for clean, compile, deploy, etc. In ant, I would expect my user to run ant -project-help to get a list of the targets with their descriptions. There doesn't appear to be anything like this with msbuild, so I was thinking of setting DefaultTargets to "Help" and adding this target: <Target Name="Help"> <Message Text="/t:Clean - Remove all bin folders and generated files"/> <Message Text="/t:Compile - Generate assembly"/> <Message Text="/t:Deploy - Install the assembly"/> </Target> When I run msbuild, I see this: Microsoft (R) Build Engine Version 3.5.30729.1 [Microsoft .NET Framework, Version 2.0.50727.3053] Copyright (C) Microsoft Corporation 2007.

Build succeeded. 0 Warning(s) 0 Error(s) Time Elapsed 00:00:00.05 My target description are hidden among all the other output. It feels like I have a paradigm-mismatch here.

HTG Explains: Why You Shouldn’t Use a Task Killer On Android

- by Chris Hoffman

Some people think that task killers are important on Android. By closing apps running in the background, you’ll get improved performance and battery life – that’s the idea, anyway. In reality, task killers can reduce your performance and battery life. Task killers can force apps running in the background to quit, removing them from memory. Some task killers do this automatically. However, Android can intelligently manage processes on its own – it doesn’t need a task killer.

BPM 11g - Dynamic Task Assignment with Multi-level Organization Units

- by Mark Foster

I've seen several requirements to have a more granular level of task assignment in BPM 11g based on some value in the data passed to the process. Parametric Roles is normally the first port of call to try to satisfy this requirement, but in this blog we will show how a lot of use-cases can be satisfied by the easier to implement and flexible Organization Unit. The Use-Case Task assignment is to an approval group containing several users. At runtime, a location value in the input data determines which of the particular users the task is ultimately assigned to. In this case we use the Demo Community referenced in the SOA Admin Guide, and specifically the "LoanAnalyticGroup" which contains three users; "szweig", "mmitch" & "fkafka". In our scenario we would like to assign a task to "szweig" if the input data specifies that the location is "JapanCentral", to "fkafka" if the location is "JapanNorth" and to "mmitch" if "JapanSouth", and to all of them if the location is "Japan" i.e.... The Process Simple one human task process.... In the output data association of the "Start" activity we need to set the value of the "Organization Unit" predefined variable based on the input data (note that the predefined variables can only be set on output data associations).... ...and in the output data association of the human activity we will reset the "Organization Unit" to empty, always good practice to ensure that the Organization Unit will not be used for any subsequent human activities for which we do not require it.... Set Up the Organization Unit Log in to the BPM Workspace with an administrator user (weblogic/welcome1 in our case) and choose the "Administration" option. Within "Roles" assign the "ProcessOwner" swim-lane for our process to "LoanAnalyticGroup".... Within "Organization Units" we can model our organization.... "Root Organization Unit" as "Japan" and "Child Organization Unit" as "Central", "South" & "North" as shown. As described previously, add user "szweig" to "Central", "mmitch" to "South" and "fkafka" to "North".... Test the Process Invalid Data First let us test with invalid data in the input to see what the consequences are, here we use "X" as input.... ...and looking at the instance we can see it has errored.... Organization Unit Root Level Assignment Now let us see what happens if we have "Japan" in the input data.... ...looking in the "flow trace" we can see that the task has been assigned.... ... but who has the task been assigned to ? Let us look in the BPM Workspace for user "szweig".... ...and for "mmitch".... ... and for "fkafka".... ...so we can see that with an Organization Unit at "Root" level we have successfully assigned the task to all users. Organization Unit Child Level Assignment Now let us test with "Japan/North" in the input data.... ...and looking in "fkafka" workspace we see the task has been assigned, remember, he was associated with "JapanNorth".... ... but what about the workspace of "szweig".... ...no tasks assigned, neither has "mmitch", just as we expected. Summary We have seen in this blog how to easily implement multi-level dynamic task routing using Organization Units, a common use-case and a simpler solution than Parametric Roles.

Overflow exception while performing parallel factorization using the .NET Task Parallel Library (TPL

- by Aviad P.

Hello, I'm trying to write a not so smart factorization program and trying to do it in parallel using TPL. However, after about 15 minutes of running on a core 2 duo machine, I am getting an aggregate exception with an overflow exception inside it. All the entries in the stack trace are part of the .NET framework, the overflow does not come from my code. Any help would be appreciated in figuring out why this happens.

How you can extend Tasklists in Fusion Applications

- by Elie Wazen

In this post we describe the process of modifying and extending a Tasklist available in the Regional Area of a Fusion Applications UI Shell. This is particularly useful to Customers who would like to expose Setup Tasks (generally available in the Fusion Setup Manager application) in the various functional pillars workareas. Oracle Composer, the tool used to implement such extensions allows changes to be made at runtime. The example provided in this document is for an Oracle Fusion Financials page. Let us examine the case of a customer role who requires access to both, a workarea and its associated functional tasks, and to an FSM (setup) task. Both of these tasks represent ADF Taskflows but each is accessible from a different page. We will show how an FSM task is added to a Functional tasklist and made accessible to a user from within a single workarea, eliminating the need to navigate between the FSM application and the Functional workarea where transactions are conducted. In general, tasks in Fusion Applications are grouped in two ways: Setup tasks are grouped in tasklists available to implementers in the Functional Setup Manager (FSM). These Tasks are accessed by implementation users and in general do not represent daily operational tasks that fit into a functional business process and were consequently included in the FSM application. For these tasks, the primary organizing principle is precedence between tasks. If task "Manage Suppliers" has prerequisites, those tasks must precede it in a tasklist. Task Lists are organized to efficiently implement an offering. Tasks frequently performed as part of business process flows are made available as links in the tasklist of their corresponding menu workarea. The primary organizing principle in the menu and task pane entries is to group tasks that are generally accessed together. Customizing a tasklist thus becomes required for business scenarios where a task packaged under FSM as a setup task, is for a particular customer a regular maintenance task that is accessed for record updates or creation as part of normal operational activities and where the frequency of this access merits the inclusion of that task in the related operational tasklist A user with the role of maintaining Journals in General Ledger is also responsible for maintaining Chart of Accounts Mappings. In the Fusion Financials Product Family, Manage Journals is a task available from within the Journals Menu whereas Chart of Accounts Mapping is available via FSM under the Define Chart of Accounts tasklist Figure 1. The Manage Chart of Accounts Mapping Task in FSM Figure 2. The Manage Journals Task in the Task Pane of the Journals Workarea Our goal is to simplify cross task navigation and allow the user to access both tasks from a single tasklist on a single page without having to navigate to FSM for the Mapping task and to the Journals workarea for the Manage task. To accomplish that, we use Oracle Composer to customize the Journals tasklist by adding to it the Mapping task. Identify the Taskflow name and path of the FSM Task The first step in our process is to identify the underlying taskflow for the Manage Chart of Accounts Mappings task. We select to Setup and Maintenance from the Navigator to launch the FSM Application, and we query the task from Manage Tasklists and Tasks Figure 3. Task Details including Taskflow path The Manage Chart of Accounts Mapping Task Taskflow is: /WEB-INF/oracle/apps/financials/generalLedger/sharedSetup/coaMappings/ui/flow /CoaMappingsMainAreaFlow.xml#CoaMappingsMainAreaFlow We copy that value and use it later as a parameter to our new task in the customized Journals Tasklist. Customize the Journals Page A user with Administration privileges can start the run time customization directly from the Administration Menu of the Global Area. This customization is done at the Site level and once implemented becomes available to all users with access to the Journals Workarea. Figure 4. Customization Menu The Oracle Composer Window is displayed in the same browser and the Hierarchy of the page component is displayed and available for modification. Figure 5. Oracle Composer In the composer Window select the PanelFormLayout node and click on the Edit Button. Note that the selected component is simultaneously highlighted in the lower pane in the browser. In the Properties popup window, select the Tasks List and Task Properties Tab, where the user finds the hierarchy of the Tasklist and is able to Edit nodes or create new ones. src="https://blogs.oracle.com/FunctionalArchitecture/resource/TL5.jpg" Figure 6. The Tasklist in edit mode Add a Child Task to the Tasklist In the Edit Window the user will now create a child node at the desired level in the hierarchy by selecting the immediate parent node and clicking on the insert node button. This process requires four values to be set as described in Table 1 below. Parameter Value How to Determine the Value Focus View Id /JournalEntryPage This is the Focus View ID of the UI Shell where the Tasklist we want to customize is. A simple way to determine this value is to copy it from any of the Standard tasks on the Tasklist Label COA Mapping This is the Display name of the Task as it will appear in the Tasklist Task Type dynamicMain If the value is dynamicMain, the page contains a new link in the Regional Area. When you click the link, a new tab with the loaded task opens Taskflowid /WEB-INF/oracle/apps/financials/generalLedger/sharedSetup/ coaMappings/ui/flow/ CoaMappingsMainAreaFlow.xml#CoaMappingsMainAreaFlow This is the Taskflow path we retrieved from the Task Definition in FSM earlier in the process Table 1. Parameters and Values for the Task to be added to the customized Tasklist Figure 7. The parameters window of the newly added Task Access the FSM Task from the Journals Workarea Once the FSM task is added and its parameters defined, the user saves the record, closes the Composer making the new task immediately available to users with access to the Journals workarea (Refer to Figure 8 below). Figure 8. The COA Mapping Task is now visible and can be invoked from the Journals Workarea Additional Considerations If a Task Flow is part of a product that is deployed on the same app server as the Tasklist workarea then that task flow can be added to a customized tasklist in that workarea. Otherwise that task flow can be invoked from its parent product’s workarea tasklist by selecting that workarea from the Navigator menu. For Example The following Taskflows belong respectively to the Subledger Accounting, and to the General Ledger Products. /WEB-INF/oracle/apps/financials/subledgerAccounting/accountingMethodSetup/mappingSets/ui/flow/MappingSetFlow.xml#MappingSetFlow /WEB-INF/oracle/apps/financials/generalLedger/sharedSetup/coaMappings/ui/flow/CoaMappingsMainAreaFlow.xml#CoaMappingsMainAreaFlow Since both the Subledger Accounting and General Ledger products are part of the LedgerApp J2EE Applicaton and are both deployed on the General Ledger Cluster Server (Figure 8 below), the user can add both of the above taskflows to the tasklist in the /JournalEntryPage FocusVIewID Workarea. Note: both FSM Taskflows and Functional Taskflows can be added to the Tasklists as described in this document Figure 8. The Topology of the Fusion Financials Product Family. Note that SubLedger Accounting and General Ledger are both deployed on the Ledger App Conclusion In this document we have shown how an administrative user can edit the Tasklist in the Regional Area of a Fusion Apps page using Oracle Composer. This is useful for cases where tasks packaged in different workareas are frequently accessed by the same user. By making these tasks available from the same page, we minimize the number of steps in the navigation the user has to do to perform their transactions and queries in Fusion Apps. The example explained above showed that tasks classified as Setup tasks, meaning made accessible to implementation users from the FSM module can be added to the workarea of their respective Fusion application. This eliminates the need to navigate to FSM to access tasks that are both setup and regular maintenance tasks.

Background task in mobile phone to access a secure element and a web server

- by Splryxx

Is it possible in a GSM mobile phone OS (e.g. Android, Win Mo, Symbian, etc.) to have some kind of background task or application able to exchange data at the same time with a web server and a secure element of the mobile? The purpose if for the web server to be able to push APDUs to the secure element (an retrieve response APDUs) without activating the IHM of the mobile. NB: I know that this is possible when the secure element is the one managing the GSM baseband, for example using BIP as described in Ulysse specifications. My question is only when using another secure element (e.g. Java Card in a microSD).

SSIS Send Mail Task and ForceExecutionValue Error

- by Kevin Shyr

I tried to use the "ForcedExecutionValue" on several Send Mail Tasks and log the execution into a ExecValueVariable so that at the end of the package I can log into a table to say whether the data check is successful or not (by determine whether an email was sent out) I set up a Boolean variable that is accessible at the package level, then set up my Send Mail Task as the screenshot below with Boolean as my ForcedExecutionValueType. When I run the package, I got the error described below. Just to make sure this is not another issue of SSIS having with Boolean type ( you also can't set variable value from xp_cmdshell of type Boolean), I used variables of types String, Int32, DateTime with the corresponding ForcedExecutionValueType. The only way to get around this error, was to set my variable to type Object, but then when you try to get the value out later, the Object is null. I didn't spend enough time on this to see whether it's really a bug in SSIS or not, or is this just how Send Mail Task works. Just want to log the error and will circle back on this later to narrow down the issue some more. In the meantime, please share if you have run into the same problem. The current workaround is to attach a script task at the end. Also, need to note 2 existing limitation: Data check needs to be done serially because every check needs to be inner join to a master table. The master table has all the data in a single XML column and hence need to be retrieved with XQuery (a fundamental design flaw that needs to be changed) The next iteration will be to change this design into a FOR loop and pull out the checking query from a table somewhere with all the info needed for email task, but is being put to the back of the priority. Error Message: Error: 0xC001F009 at CountCheckBetweenODSAndCleanSchema: The type of the value being assigned to variable "User::WasErrorEmailEverSent" differs from the current variable type. Variables may not change type during execution. Variable types are strict, except for variables of type Object. Error: 0xC0019001 at Send Mail Task on count mismatch: The wrapper was unable to set the value of the variable specified in the ExecutionValueVariable property.

C++ Parallel Asynchonous task

- by Doodlemeat

I am currently building a randomly generated terrain game where terrain is created automatically around the player. I am experiencing lag when the generated process is active, as I am running quite heavy tasks with post-processing and creating physics bodies. Then I came to mind using a parallel asynchronous task to do the post-processing for me. But I have no idea how I am going to do that. I have searched for C++ std::async but I believe that is not what I want. In the examples I found, a task returned something. I want the task to change objects in the main program. This is what I want: // Main program // Chunks that needs to be processed. // NOTE! These chunks are already generated, but need post-processing only! std::vector<Chunk*> unprocessedChunks; And then my task could look something like this, running like a loop constantly checking if there is chunks to process. // Asynced task if(unprocessedChunks.size() > 0) { processChunk(unprocessedChunks.pop()); } I know it's not far from easy as I wrote it, but it would be a huge help for me if you could push me at the right direction. In Java, I could type something like this: asynced_task = startAsyncTask(new PostProcessTask()); And that task would run until I do this: asynced_task.cancel();

Accessing running task scheduled with java.util.Timer

- by jbatista

I'm working on a Java project where I have created a class that looks like this (abridged version): public class Daemon { private static Timer[] timerarray=null; private static Daemon instance=null; protected Daemon() { ArrayList<Timer> timers = new ArrayList<Timer>(); Timer t = new Timer("My application"); t.schedule(new Worker(), 10000,30000); timers.add(t); //... timerarray = timers.toArray(new Timer[]{}); } public static Daemon getInstance() { if(instance==null) instance=new Daemon(); return instance; } public SomeClass getSomeValueFromWorker() { return theValue; } ///////////////////////////////////////////// private class Worker extends TimerTask { public Worker() {} public void run() { // do some work } public SomeReturnClass someMethod(SomeType someParameter) { // return something; } } ///////////////////////////////////////////// } I start this class, e.g. by invoking daemon.getInstance();. However, I'd like to have some way to access the running task objects' methods (for example, for monitoring the objects' state). The Java class java.util.Timer does not seem to provide the means to access the running object, it just schedules the object instance extending TimerTask. Are there ways to access the "running" object instanciated within a Timer? Do I have to subclass the Timer class with the appropriate methods to somehow access the instance (this "feels" strange, somehow)? I suppose someone might have done this before ... where can I find examples of this "procedure"? Thank you in advance for your feedback.

Task Queue stopped working

- by pocoa

I was playing with Goole App Engine Task Queue API to learn how to use it. But I couldn't make it trigger locally. My application is working like a charm when I upload to Google servers. But it doesn't trigger locally. All I see from the admin is the list of the tasks. But when their ETA comes, they just pass it. It's like they runs but they fails and waiting for the retries. But I can't see these events on command line. When I try to click "Run" on admin panel, it runs successfuly and I can see these requests from the command line. I'm using App Engine SDK 1.3.4 on Linux with google-app-engine-django. I'm trying to find the problem from 3 hours now and I couldn't find it. It's also very hard to debug GAE applications. Because debug messages do not appear on console screen. Thanks.

Output redirection still with colors in PowerShell

- by stej

Suppose I run msbuild like this: function Clean-Sln { param($sln) MSBuild.exe $sln /target:Clean } Clean-Sln c:\temp\SO.sln In Posh console the output is in colors. That's pretty handy - you spot colors just by watching the output. And e.g. not important messages are grey. Question I'd like to add ability to redirect it somewhere like this (simplified example): function Clean-Sln { param($sln) MSBuild.exe $sln /target:Clean | Redirect-AccordingToRedirectionVariable } $global:Redirection = 'Console' Clean-Sln c:\temp\SO.sln $global:Redirection = 'TempFile' Clean-Sln c:\temp\Another.sln If I use 'Console', the cmdlet/function Redirect-AccordingToRedirectionVariable should output the msbuild messages with colors the same way as the output was not piped. In other words - it should leave the output as it is. If I use 'TempFile', Redirect-AccordingToRedirectionVariable will store the output in a temp file. Is it even possible? I guess it is not :| Or do you have any advice how to achieve the goal? Possible solution: if ($Redirection -eq 'Console) { MSBuild.exe $sln /target:Clean | Redirect-AccordingToRedirectionVariable } else { MSBuild.exe $sln /target:Clean | Out-File c:\temp.txt } But if you imagine there can be many many msbuild calls, it's not ideal. Don't be shy to tell me any new suggestion how to cope with it ;) Any background info about redirections/coloring/outpu is welcome as well. (The problem is not msbuild specific, the problem touches any application that writes colored output)

chaining array of tasks with continuation

- by Andrei Cristof

I have a Task structure that is a little bit complex(for me at least). The structure is: (where T = Task) T1, T2, T3... Tn. There's an array (a list of files), and the T's represent tasks created for each file. Each T has always two subtasks that it must complete or fail: Tn.1, Tn.2 - download and install. For each download (Tn.1) there are always two subtasks to try, download from two paths(Tn.1.1, Tn.1.2). Execution would be: First, download file: Tn1.1. If Tn.1.1 fails, then Tn.1.2 executes. If either from download tasks returns OK - execute Tn.2. If Tn.2 executed or failed - go to next Tn. I figured the first thing to do, was to write all this structure with jagged arrays: private void CreateTasks() { //main array Task<int>[][][] mainTask = new Task<int>[_queuedApps.Count][][]; for (int i = 0; i < mainTask.Length; i++) { Task<int>[][] arr = GenerateOperationTasks(); mainTask[i] = arr; } } private Task<int>[][] GenerateOperationTasks() { //two download tasks Task<int>[] downloadTasks = new Task<int>[2]; downloadTasks[0] = new Task<int>(() => { return 0; }); downloadTasks[1] = new Task<int>(() => { return 0; }); //one installation task Task<int>[] installTask = new Task<int>[1] { new Task<int>(() => { return 0; }) }; //operations Task is jagged - keeps tasks above Task<int>[][] operationTasks = new Task<int>[2][]; operationTasks[0] = downloadTasks; operationTasks[1] = installTask; return operationTasks; } So now I got my mainTask array of tasks, containing nicely ordered tasks just as described above. However after reading the docs on ContinuationTasks, I realise this does not help me since I must call e.g. Task.ContinueWith(Task2). I'm stumped about doing this on my mainTask array. I can't write mainTask[0].ContinueWith(mainTask[1]) because I dont know the size of the array. If I could somehow reference the next task in the array (but without knowing its index), but cant figure out how. Any ideas? Thank you very much for your help. Regards,

How do I update an xml file with msbuild with two namespaces?

- by c3rin

This msbuild below task can take into account one namespace, but in the case where I'm updating an mxml (flex) that has a mix of namespaces, can I use this task or another msbuild task to do the update? <XmlUpdate Prefix="fx" Namespace="http://ns.adobe.com/mxml/2009" XmlFileName="myFlexApp.mxml" Xpath="//mx:Application/fx:Declarations/fx:String[@id='stringId']" Value="xxxxx"> Here is the flex xml I'm trying to update: <mx:Application xmlns:fx="http://ns.adobe.com/mxml/2009" xmlns:mx="library://ns.adobe.com/flex/mx" xmlns:s="library://ns.adobe.com/flex/spark"> <fx:Declarations> <fx:String id="stringId">UPDATE_ME</fx:String> </fx:Declarations></mx:Application>

How do I get MSBuild Task to generate XML Documents when building a solution?

- by toba303

I have a solution with lots of projects. Each project is configured to generate the XML documentation file when building in Debug-Mode (which is default). That works when I build in Visual Studio 2008. In my build script on my integration server I advise MSBuild to build the whole solution, but it won't generate the documentation files. What can I do? I already tried to explicitly give the Debug-Condition to the build process, but it makes no difference. <Target Name="BuilSolution"> <MSBuild Projects="C:\Path\To\MySolution.sln" targets="Build" Properties="SolutionConfigurationPlatforms='Debug|Any CPU'"/> </Target> There seem to be some ideas to solve this problem when building single projects, but I can't afford to do this, so I need a hint for doing it this way. Thanks in advance!

CCNet web dashboard not showing anything when MSBuild fails

- by cfdev9

I have a simple project in ccnet using svn & msbuild only. There is a 30 second trigger for svn and the msbuild file compiles a web application then copies it to a numbered build folder. When an error occurs in the msbuild task I get a failed build. When I view a failed build in the web dashboard I can see the 'Modifications since last build' section in the dashboard, but nothing else. I have to click on the build log and read through all of the xml in the error log to see what the error was. Why won't the dashboard show the errors from the build log? I haven't changed anything in the dashboard.config since installing ccnet. Dashboard Version : 1.5.7256.1 <project name="SimpleWebapp1"> <artifactDirectory>C:\Program Files\CruiseControl.NET\server\SimpleWebapp1\Artifacts\</artifactDirectory> <triggers> <intervalTrigger name="continuous" seconds="30" buildCondition="IfModificationExists" initialSeconds="5" /> </triggers> <sourcecontrol type="svn"> <executable>C:\Program Files\CollabNet\Subversion Client\svn.exe</executable> <trunkUrl>https://server:8443/svn/SimpleWebapp1/trunk</trunkUrl> <workingDirectory>D:\CCNetSandbox\SimpleWebapp1</workingDirectory> <username>username</username> <password>password</password> </sourcecontrol> <tasks> <msbuild> <executable> C:\WINDOWS\Microsoft.NET\Framework\v3.5\MSBuild.exe </executable> <workingDirectory> D:\CCNetSandbox\SimpleWebapp1 </workingDirectory> <projectFile>SimpleWebapp1.build</projectFile> <buildArgs>/p:Configuration=Debug /p:Platform="Any CPU"</buildArgs> <targets>CompileLatest</targets> <timeout>900</timeout> <logger>ThoughtWorks.CruiseControl.MsBuild.XMLLogger, C:\Program Files\CruiseControl.NET\server\ThoughtWorks.CruiseControl.MsBuild.dll</logger> </msbuild> </tasks> <publishers> <xmllogger /> <buildpublisher> <publishDir>C:\Program Files\CruiseControl.NET\server\SimpleWebapp1\Artifacts\</publishDir> <useLabelSubDirectory>true</useLabelSubDirectory> </buildpublisher> </publishers> </project>

Ant get task throws "get doesn't support nested resources element" error

The following ant xml should work according to documentation, but does not. Can anyone tell me if I'm doing something wrong. The get task should support the nested "resources" element in Ant 1.7.1 which is the version I'm using: -- <target name="setup"> <tstamp/>     <property name="framework_wa" value="../../../framework"/> <property name="xpbuw_wa" value="../../../xpbuw"/> <property name="xpb_wa" value="../../../xpb"/> <property name="bil_wa" value="../.."/>  <property name="out" value="${user.dir}"/>  <property name="locale" value="us"/>  <property name="contextRoot" value="xpertBridge"/> <property name="build_dir" value="${out}/${release}/build"/> <property name="distrib_dir" value="${out}/${release}/distrib"/> <property name="build.number" value="-1"/>  <get dest="${lib}"> <resources> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=central&g=soap&a=soap&v=2.3.1&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=JBOSS&g=apache-fileupload&a=commons-fileupload&v=1.0&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=regexp&a=regexp&v=1.1&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=javax.mail&a=mail&v=1.2&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=com.ibm.ws.webservices&a=webservices.thinclient&v=6.1.0&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=avalon-framework&a=avalon-framework&v=4.2.0&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=jimi&a=jimi&v=1.0&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=batik&a=batik-all&v=1.6&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=bsf&a=bsf&v=2.3.0&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=rhino&a=js&v=1.5R3&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=central&g=commons-io&a=commons-io&v=1.1&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=central&g=commons-logging&a=commons-logging&v=1.0.4&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=xmlgraphics&a=commons&v=1.0&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=barcode4j&a=barcode4j&v=trunkBIL&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=com.ibm&a=fmcojagt&v=6.1&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=com.allfinanz&a=ejbserversupport&v=1.0&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=com.sun&a=jce&v=1.0&e=zip"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=ssce&a=ssce&v=5.8&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=com.ibm&a=mq&v=5.1&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=com.ibm&a=mqjms&v=5.1&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=NetServerRemote&a=NetServerRemote&v=1.0&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=NetServerRMI&a=NetServerRMI&v=1.0&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=jwsdp&a=saaj-api&v=1.5&e=jar&c=api"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=jwsdp&a=saaj-impl&v=1.5&e=jar&c=impl"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=org.apache.xmlgraphics&a=fop&v=0.92b&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=xerces&a=dom3-xml-apis&v=1.0&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=org.apache&a=derbynet&v=10.0.2&e=jar"/> <url url="http://repo.fms.allfinanz.com/service/local/artifact/maven/redirect?r=thirdparty&g=com.sun&a=jsse&v=1.0&e=jar"/> </resources> </get> </target>
