  • JAVA: Can't get context parameters in Filter

    - by DaTval
    Hello, I have a filter and parameters in web.xml web.xml is like this: <filter> <description> </description> <display-name>AllClassFilter</display-name> <filter-name>AllClassFilter</filter-name> <filter-class>com.datval.homework.AllClassFilter</filter-class> <init-param> <param-name>DB_URL</param-name> <param-value>jdbc:derby:C:/Users/admin/workspace/homework03/homework/databases/StudentsDB;create=true</param-value> </init-param> <init-param> <param-name>DB_DIALECT</param-name> <param-value>org.hibernate.dialect.DerbyDialect</param-value> </init-param> <init-param> <param-name>DB_DRIVER</param-name> <param-value>org.apache.derby.jdbc.EmbeddedDriver</param-value> </init-param> </filter> mapping is working well. But I can't get this parameters in my filter. public void init(FilterConfig config) throws ServletException { // TODO Auto-generated method stub debugMessage = config.getInitParameter("debugMessage"); ctx = config.getServletContext(); } public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { // TODO Auto-generated method stub // place your code here ctx.log("Start - " + debugMessage); String myDbUrl = ctx.getInitParameter("DB_URL"); String DB_DIALECT = ctx.getInitParameter("DB_DIALECT"); String DB_DRIVER = ctx.getInitParameter("DB_DRIVER"); Map<String,String> pr = new HashMap<String,String>(); pr.put("hibernate.connection.url", myDbUrl); pr.put("hibernate.dialect", DB_DIALECT); pr.put("hibernate.connection.driver_class", DB_DRIVER); EntityManagerFactory emf = Persistence.createEntityManagerFactory("students",pr); EntityManager em = emf.createEntityManager(); request.setAttribute("em", em); chain.doFilter(request, response); em.close(); ctx.log("end - " + debugMessage); } I have checked and myDbUrl is null. What I'm doing wrong? Any idea? Sorry about code, I will change it later :)

  • MvcExtensions - ActionFilter

    - by kazimanzurrashid
    One of the thing that people often complains is dependency injection in Action Filters. Since the standard way of applying action filters is to either decorate the Controller or the Action methods, there is no way you can inject dependencies in the action filter constructors. There are quite a few posts on this subject, which shows the property injection with a custom action invoker, but all of them suffers from the same small bug (you will find the BuildUp is called more than once if the filter implements multiple interface e.g. both IActionFilter and IResultFilter). The MvcExtensions supports both property injection as well as fluent filter configuration api. There are a number of benefits of this fluent filter configuration api over the regular attribute based filter decoration. You can pass your dependencies in the constructor rather than property. Lets say, you want to create an action filter which will update the User Last Activity Date, you can create a filter like the following: public class UpdateUserLastActivityAttribute : FilterAttribute, IResultFilter { public UpdateUserLastActivityAttribute(IUserService userService) { Check.Argument.IsNotNull(userService, "userService"); UserService = userService; } public IUserService UserService { get; private set; } public void OnResultExecuting(ResultExecutingContext filterContext) { // Do nothing, just sleep. } public void OnResultExecuted(ResultExecutedContext filterContext) { Check.Argument.IsNotNull(filterContext, "filterContext"); string userName = filterContext.HttpContext.User.Identity.IsAuthenticated ? filterContext.HttpContext.User.Identity.Name : null; if (!string.IsNullOrEmpty(userName)) { UserService.UpdateLastActivity(userName); } } } As you can see, it is nothing different than a regular filter except that we are passing the dependency in the constructor. Next, we have to configure this filter for which Controller/Action methods will execute: public class ConfigureFilters : ConfigureFiltersBase { protected override void Configure(IFilterRegistry registry) { registry.Register<HomeController, UpdateUserLastActivityAttribute>(); } } You can register more than one filter for the same Controller/Action Methods: registry.Register<HomeController, UpdateUserLastActivityAttribute, CompressAttribute>(); You can register the filters for a specific Action method instead of the whole controller: registry.Register<HomeController, UpdateUserLastActivityAttribute, CompressAttribute>(c => c.Index()); You can even set various properties of the filter: registry.Register<ControlPanelController, CustomAuthorizeAttribute>( attribute => { attribute.AllowedRole = Role.Administrator; }); The Fluent Filter registration also reduces the number of base controllers in your application. It is very common that we create a base controller and decorate it with action filters and then we create concrete controller(s) so that the base controllers action filters are also executed in the concrete controller. You can do the  same with a single line statement with the fluent filter registration: Registering the Filters for All Controllers: registry.Register<ElmahHandleErrorAttribute>(new TypeCatalogBuilder().Add(GetType().Assembly).Include(type => typeof(Controller).IsAssignableFrom(type))); Registering Filters for selected Controllers: registry.Register<ElmahHandleErrorAttribute>(new TypeCatalogBuilder().Add(GetType().Assembly).Include(type => typeof(Controller).IsAssignableFrom(type) && (type.Name.StartsWith("Home") || type.Name.StartsWith("Post")))); You can also use the built-in filters in the fluent registration, for example: registry.Register<HomeController, OutputCacheAttribute>(attribute => { attribute.Duration = 60; }); With the fluent filter configuration you can even apply filters to controllers that source code is not available to you (may be the controller is a part of a third part component). That’s it for today, in the next post we will discuss about the Model binding support in MvcExtensions. So stay tuned.

  • Configure postfix to filter email into hold queue

    - by Ian
    Hey, I would like postfix to send all emails received on SMTP off to an external process, which will decide whether to allow them through as normal, or whether to put them into the hold queue (or another quarantine area), where they have to wait for admin approval. I was thinking of doing this with an after-queue content filter, which uses pipe(8) to run a script on each message, and the script itself will spawn "postsuper -h " if it decides to put the message on hold. Then the admin can do postsuper -d or -r to delete or pass the message on as appropriate. So, my questions are - a) will this work, and b) is this the best way to do it? Would a milter or another type of content filter be a better approach?

  • WPF: Filter TreeView without collapsing it's nodes

    - by Julian Lettner
    This one is a follow-up question. I filter the top level nodes of a TreeView control like shown below. private void ApplyFilterHandler(object sender, RoutedEventArgs e) { if (_filterCheckBox.IsChecked.Value) CollectionViewSource.GetDefaultView(TopLevelNodes).Filter += MyFilter; else CollectionViewSource.GetDefaultView(TopLevelNodes).Filter -= MyFilter; } . <TreeView ItemsSource="{Binding TopLevelNodes}"> ... </TreeView> When the user applies the filter all nodes get collapsed. Question How can I hide certain nodes in a tree while retaining the expand state of the other nodes? Can someone explain, what happens internally on ICollectionView.Filter += MyFilter. Thanks for your time.

  • NHibernate Many-To-One on Joined Sublcass with Filter

    - by Nathan Roe
    I have a class setup that looks something like this: public abstract class Parent { public virtual bool IsDeleted { get; set; } } public class Child : Parent { } public class Other { public virtual ICollection<Child> Children { get; set; } } Child is mapped as a joined-subclass of Parent. Childen is mapped as a Many-To-One bag. The bag has a filter applied to it named SoftDeletableFilter. The filter mapping looks like: <filter-def name="SoftDeleteableFilter" condition="(IsDeleted = 0 or IsDeleted is null)" /> That problem is that when Other.Children is loaded the filter is being applied to the Child table and not the parent table. Is there any way to tell NHibernate to apply the filter to the parent class?

  • Use filter(), but work with both results

    - by Tomalak
    In jQuery, filter() reduces your result to those elements that fulfill a certain condition. This splits the list in two parts. Working with the "good half" of the elements is easy: $("some selector").filter(function() { // determine result... return result; }).each( /* do something */ ); But how can I work with the "other half" of my elements, too - but without doing the equivalent of this: $("some selector").filter(function() { // determine result... return !result; }).each( /* do something else */ ); Basically, I'd like to feed two separate /* do something */ parts to a single filter. One for those that match, and one for the others - without having to filter twice. Am I missing a jQuery function that does this? P.S.: I guess I could do: $("some selector").each(function() { // determine result... if (result) /* do something */ else /* do something else */ }); But I was hoping for something nicer.

  • BindingSource.Filter does not work with affected rows in DataSet

    - by Artru
    I created DataGridView in WinForms App. Then at the initializing create DataSet and fill it with some data, bind to DataGridView . I added textBox as a filter. `myBindingSource = new BindingSource(); myBindingSource.DataSource = ds; myBindingSource.DataMember = dt.TableName; dataGridView1.DataSource = myBindingSource;` string strCmd = "some filter query"; myBindingSource.Filter = strCmd; It works fine with filtering. If I add or delete any row to the DataSet then new data will occur in dridview, BUT filter will not work with new data. As I found on the forums there is a Table cash, which .NET uses for filter and I want to refresh it. How can I do it?

  • [Android] Returning to a ListView with a text filter

    - by sosiouxme
    I enabled text filtering on my ListView in the expected way; adding android:textFilterEnabled=”true” in resource definition and (as I'm using a SimpleCursorAdapter) setting a FilterQueryProvider that provides a filtered cursor like so: public Cursor runQuery(CharSequence constraint) { Cursor cur = mDba.fetchTrackers(mCurrentGroupId, constraint.toString()); startManagingCursor(cur); return cur; } My question is this: once the user selects a list item, goes off to another activity, and returns to this one, how can I control the state of the filter previously applied? What I'm seeing right now is that when I return to the activity, the cursor being used is the unfiltered one set on the filter at creation, but the filter text they typed is still shown (and typing keys causes the filter to be applied). What I'd like to do is either clear the filter, or keep the filtered cursor that the activity was left with.

  • git filter-branch chmod

    - by Evan Purkhiser
    I accidental had my umask set incorrectly for the past few months and somehow didn't notice. One of my git repositories has many files marked as executable that should be just 644. This repo has one main master branch, and about 4 private feature branches (that I keep rebased on top of the master). I've corrected the files in my master branch by running find -type f -exec chmod 644 {} \; and committing the changes. I then rebased my feature branches onto master. The problem is there are newly created files in the feature branches that are only in that branch, so they weren't corrected by my massive chmod commit. I didn't want to create a new commit for each feature branch that does the same thing as the commit I made on master. So I decided it would be best to go back through to each commit where a file was made and set the permissions. This is what I tried: git filter-branch -f --tree-filter 'chmod 644 `git show --diff-filter=ACR --pretty="format:" --name-only $GIT_COMMIT`; git add .' master.. It looked like this worked, but upon further inspection I noticed that the every commit after a commit containing a new file with the proper permissions of 644 would actually revert the change with something like: diff --git a b old mode 100644 new mode 100755 I can't for the life of me figure out why this is happening. I think I must be mis-understanding how git filter-branch works. My Solution I've managed to fix my problem using this command: git filter-branch -f --tree-filter 'FILES="$FILES "`git show --diff-filter=ACMR --pretty="format:" --name-only $GIT_COMMIT`; chmod 644 $FILES; true' development.. I keep adding onto the FILES variable to ensure that in each commit any file created at some point has the proper mode. However, I'm still not sure I really understand why git tracks the file mode for each commit. I had though that since I had fixed the mode of the file when it was first created that it would stay that mode unless one of my other commits explicit changed it to something else. That did not appear to the be the case. The reason I thought that this would work is from my understanding of rebase. If I go back to HEAD~5 and change a line of code, that change is propagated through, it doesn't just get changed back in HEAD~4.

  • Sync database with filter using SyncOrchestrator with Sync Framework 2.0

    - by Flo
    Hi, I want to synchronize two SQL databases. But since one of the databases only requires a subset of the data I am looking for a filter option. Is there a possibility to add a Filter to the SyncOrchestrator or do I have to add the filter to the SyncProvider? According to this: http://social.microsoft.com/Forums/en-US/uklaunch2007ado.net/thread/35d4deb8-a861-4fe3-a395-d175e14c353f it is not possible to filter with the DbSyncProvider. Quote: "I understand your scenario, and the hebavior of the DbSyncProvider is due to the current limitation. DbSyncProvider is built on top of the Microsoft Sync Framework that can support filtering. Unfortunately, DbSyncProvider does not yet." But that post is quite old, maybe that has changed now. I am working with this example at the moment: http://msdn.microsoft.com/en-us/library/cc807255.aspx but I can't figure out how to add filtering here.

  • Breakpoints not working in Delphi 6 DirectShow source filter

    - by Robert Oschler
    I'm trying to debug my DirectShow source filter. I'm using Delphi Pro 6 on Windows XP along with the DSPACK component library. I'm using Skype as my host application, which I set in the Parameters option in the Run menu, for testing my source filter DLL (ax file extension). Skype runs fine and I see a stream of my OutputDebugString messages in the Event Viewer, but none of my breakpoints are ever hit. In my Project Settings I have optimizations off, stack frames on, debug DCUs on, Range Checking on, and Overflow checking on. Each time I modify my code and run a test I: Do a full build Unregister the DirectShow filter (regsvr32 /u) Register the DirectShow filter (regsvr32) Run Skype as my Host application from the IDE When an Exception occurs, the IDE does trap it and pops up an error dialog box with the option to view the assembler code in the CPU window. However none of my breakpoints are being hit. Can anyone tell me how to get breakpoints working? Thanks.

  • WPF: Bind/Apply Filter on Boolean Property

    - by Julian Lettner
    I want to apply a filter to a ListBox accordingly to the IsSelected property of a CheckBox. At the moment I have something like this. XAML <CheckBox Name="_filterCheckBox" Content="Filter list" Checked="ApplyFilterHandler"/> <ListBox ItemsSource="{Binding SomeItems}" /> CodeBehind public ObservableCollection<string> SomeItems { get; private set; } private void ApplyFilterHandler(object sender, RoutedEventArgs e) { if (_filterCheckBox.IsChecked.Value) CollectionViewSource.GetDefaultView(SomeItems).Filter += MyFilter; else CollectionViewSource.GetDefaultView(SomeItems).Filter -= MyFilter; } private bool MyFilter(object obj) { return ... } It works but this solution feels like the old-fashioned way (Windows Forms). Question: Is it possible to achieve this with Bindings / in XAML? Thanks for your time.

  • Using a Filter to serve a specific page?

    - by user246114
    Hi, I am using a class which implements Filter for my jsp stuff. It looks like this: public class MyFilter implements Filter { public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException { request.getRequestDispatcher("mypage.jsp").forward(request, response); } } So the target, "mypage.jsp", is just sitting in my top-level directory. The filter works fine if I'm entering urls like: http://www.mysite.com/foo http://www.mysite.com/boo but if I enter a trailing slash, I'll get a 404: http://www.mysite.com/foo/ http://www.mysite.com/boo/ HTTP ERROR: 404 /foo/mypage.jsp RequestURI=/foo/mypage.jsp it seems if I enter the trailing slash, then the filter thinks I want it to look for mypage.jsp in subfolder foo or boo, but I really always want it to just find it at: http://www.mysite.com/mypage.jsp how can I do that? Thank you

  • DSP - Filter sweep effect

    - by Trap
    I'm implementing a 'filter sweep' effect (I don't know if it's called like that). What I do is basically create a low-pass filter and make it 'move' along a certain frequency range. To calculate the filter cut-off frequency at a given moment I use a user-provided linear function, which yields values between 0 and 1. My first attempt was to directly map the values returned by the linear function to the range of frequencies, as in cf = freqRange * lf(x). Although it worked ok it looked as if the sweep ran much faster when moving through low frequencies and then slowed down during its way to the high frequency zone. I'm not sure why is this but I guess it's something to do with human hearing perceiving changes in frequency in a non-linear manner. My next attempt was to move the filter's cut-off frequency in a logarithmic way. It works much better now but I still feel that the filter doesn't move at a constant perceived speed through the range of frequencies. How should I divide the frequency space to obtain a constant perceived sweep speed? Thanks in advance.

  • Redirecting the response from a filter throws an IllegalStateException

    - by Ritesh M Nayak
    I am writing a filter that will handle all authentication related tasks. My filter is a standard servlet filter as shown below @Override public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException { UserSession attribute = (UserSession)request.getSession().getAttribute("user_session_key"); if(attribute!=null && attribute.isValid()) { //proceed as usual, chain.doFilter(req, res); return; } else { //means the user is not authenticated, so we must redirect him/her to the login page ((HttpServletResponse)res).sendRedirect("loginpage"); return; } } But when I do this, I get an IllegalStateException thrown by Tomcat's ResponseFacade. How do I acheive this in a filter. I read in other SO threads that in TOmcat this is a problem as the response object is already commited. How do I get past this ?

  • Javscript filter vs map problem

    - by graham.reeds
    As a continuation of my min/max across an array of objects I was wondering about the performance comparisons of filter vs map. So I put together a test on the values in my code as was going to look at the results in FireBug. This is the code: var _vec = this.vec; min_x = Math.min.apply(Math, _vec.filter(function(el){ return el["x"]; })); min_y = Math.min.apply(Math, _vec.map(function(el){ return el["x"]; })); The mapped version returns the correct result. However the filtered version returns NaN. Breaking it out, stepping through and finally inspecting the results, it would appear that the inner function returns the x property of _vec but the actual array returned from filter is the unfiltered _vec. I believe my usage of filter is correct - can anyone else see my problem?

  • javascript filter nested object based on key value

    I wish to filter a nested javascript object by the value of the "step" key: var data = { "name": "Root", "step": 1, "id": "0.0", "children": [ { "name": "first level child 1", "id": "0.1", "step":2, "children": [ { "name": "second level child 1", "id": "0.1.1", "step": 3, "children": [ { "name": "third level child 1", "id": "0.1.1.1", "step": 4, "children": []}, { "name": "third level child 2", "id": "0.1.1.2", "step": 5, "children": []} ]}, ]} ] }; var subdata = data.children.filter(function (d) { return (d.step <= 2)}); This just returns the unmodified nested object, even if I put value of filter to 1. does .filter work on nested objects or do I need to roll my own function here, advise and correct code appreciated. cjm
