• Include static file in JSP with variable filename on WebSphere 6

  - by cringe

  I'm struggling with including a static file into my JSPs on Websphere 6.0.2.17. I tried this: <% final String MY_DIR = ResourceBundle.getBundle("mybundle").getString("props.pages.wcm"); %> <% final String page = ResourceBundle.getBundle("mybundle").getString("page"); %> <% final String inc = MY_DIR + "/" + bonus; %> <%@include file="<%= inc %>"%> The path is /wcm/some/other/dir/page and I can happily print that out with out.write(inc). Unfortunatly the include (and the jsp:include) isn't including the file at all. There is no error message, but the content isn't included... The file is accessible via the browser though. Do I have to create a full JSP for this to work? I just need a HTML file.

• PHP reading 'get' veriable that may or may not have been set

  - by thecoshman

  Simply put, if you try to read the value of a get variable, what happens if said variable had not be put into the URL. Example: you request the page test.php, in that file it tries to read the value of $_GET['message']. What happens in this case? dose the value just get returned as ''? Dose this mean, that if I am always expecting a value to be entered, and am not willing to accept a value of '' that I can just do something like $foo = $_GET['bar']; if($foo == ''){ // Handle my 'error' } else { // $foo should now have a value that I can work with } Please bare in mind I know that I could use isset($_GET['bar']) But I don't just want to know if it is set, I don't care if it is or not, I just care if it has a value that is more then just an empty string.

• Cancel UDP recvfrom in C on Unix

  - by hora

  I'm just starting to learn how network programming in C works, and I've written a small program that sends messages to and from a UNIX terminal. I'm using pthreads in my program, one of which essentially just waits on recvfrom() to receive a message. However, I want to be able to close all threads properly if the users chooses to quit the program. The way I have it set up right now, a different thread just cancels the thread waiting on recvfrom, but I'm worried this might not be a good idea since I'm leaving sockets unclosed and I'm not freeing all the memory I allocated. Is there a way to cancel a recvfrom() call, or some way to run a certain routine upon cancelling a pthread? Thanks.

• Validation Rules in Webtesting using VS2010

  - by Lexipain

  I'm creating a simple webtest (Recorded Web performance test) that makes sure that a correct error message is displayed if i try to login with a username that does not exist. However, there are two types of error messages that handle incorrect login info. One is for all the usernames that do not exist and therefore are not allowed, and the other is for usernames that start with the letter 'Q' (which is not allowed for a few reasons). Now what i want to do is use the 'Find Text' validation rule and the test should pass if ONE of the 'Find Text' parameters is found, and in that case i want the second 'Find Text' rule to be ignored so it doesn't fail the test. In other words the test should always pass if one of the 'Find Test' rules is found. How can i achieve that? Is there some if,else statement that i can use for this?

• rubyCAS-client serviceValidation uri questions.

  - by ted-gehling

  php code works with this url but the rubyCAS-Client gem's `validate_service_ticket()' seems to call an SSL Validation on this url which returns an error message.

• struts validation problem in IE

  - by user265201

  I am using Struts 2.1.8 and facing validation problem in IE. I am getting the following error An exception occurred: Error. Error message: Invalid argument. I tried out to figure out the cause and found the following. My generated javascript code is: field = form.elements['district.name']; var error = "Enter only alphabets for district"; if (continueValidation && field.value != null && !field.value.match("^[a-zA-Z ]*$")) { addError(field, error); errors = true; } I tried to mock up by putting the same code in a function and calling it in onclick event. The method addError() throws the exception and the reason is field variable. If I change it to field[0], it works fine. How to fix this error?

• C++: How to build an events / messaging system without void pointers?

  - by Jarx

  I'd like to have a dynamic messaging system in my C++ project, one where there is a fixed list of existing events, events can be triggered anywhere during runtime, and where you can subscribe callback functions to certain events. There should be an option for arguments passed around in those events. For example, one event might not need any arguments (EVENT_EXIT), and some may need multiple ones (EVENT_PLAYER_CHAT: Player object pointer, String with message) The first option for making this possible is allowing to pass a void pointer as argument to the event manager when triggering an event, and receiving it in the callback function. Although: I was told that void pointers are unsafe and I shouldn't use them. How can I keep (semi) dynamic argument types and counts for my events whilst not using void pointers?

• Packaging PHPUnit tests as a PHAR archive?

  - by therefromhere

  Is it possible to package PHPUnit tests as a PHAR archive, and run them using phpunit? I've created a .phar with the follow script: $cPhar = new Phar('mytests-archive.phar', 0); $cPhar->addFile('mytest.php'); $stub = <<<ENDSTUB #! /usr/bin/php <?php Phar::mapPhar('mytest-archive.phar'); require 'phar://mytests-archive.phar/mytest.php'; __HALT_COMPILER(); ENDSTUB; $cPhar->setStub($stub); $cPhar->compressFiles(Phar::GZ); $cPhar->stopBuffering(); But when I then try running the resulting archive as follows: phpunit mytests-archive.phar I get the error message: #! /usr/bin/php PHPUnit 3.3.17 by Sebastian Bergmann. Class MyTestClass could not be found in /path/to/mytests-archive.phar Does PHPUnit not support PHAR files, or am I missing a step in my build script? (This is my first attempt at using PHAR)

• Preventing multiple reporting of the same rule violation in FxCop -- What is Id?

  - by Dave

  FxCop is currently reporting the same rule violation for a particular method -- it has two out parameters, because I want to return two values to the caller without creating a struct for it. I wonder if anonymous types would solve my problem, but I didn't know about them at the time I had written the method. Anyhow, I'm getting CheckId CA1021 reported once for each parameter. I've copied the SuppressMessage text from FxCop, and then realized that the Id for each message is different! To me, it seems like you only need the CheckId, so... what is the Id used for? I haven't been able to find information about it online. will the Id remain the same? I assume so, or SuppressMessage wouldn't work the way one would want it to is there a way to specify the SuppressMessage attribute so that it suppresses for all Ids?

• iPhone - Browsing iPhone files through computer

  - by quano

  I want to be able to send files from an iPhone app to a computer. What would be the easiest way of doing this? I've made simple server client programs before, but in those, the client has always needed to connect to the server before being able to receive messages from it. There is an app for the iPhone called iSimulate, where you put a server on a Mac (the iPhone simulator), and then you use the iSimulate app of an iTouch or iPhone to send touch events to the server. This app does not require you to type in an ip-address. Instead it presents a list of available computers that have this server up and running. How exactly is this being done? Can a server broadcast a message over a network, w/o anyone being connected to the server? How does that work? How does a client listen for that broadcast? Here's a video of the app I'm talking about: http://www.youtube.com/watch?v=N3Qpd1ycZh4

• How to make safe cast using generics in C#?

  - by TN

  I want to implement a generic method on a generic class which would allow to cast safely, see example: public class Foo<T> : IEnumerable<T> { ... public IEnumerable<R> SafeCast<R>() where T : R { return this.Select(item => (R)item); } } However, the compiler tells me that Foo<T>.SafeCast<R>() does not define parameter 'T'. I understand this message that I cannot specify a constraint on T in the method since it is not defined in the method. But how can I specify an inverse constraint?

• how escape quotes when inserting into database in PHP

• System.IndexOutOfRange Exception Sending Gridview Values to DataTable

  - by SidC

  Hello, I am writing an ASP.NET 3.5 application and need to send gridview values to a datatable for use in a listbox control as part of a quote process. I have written the following VB code in my Page_Load: Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load Dim dtSelParts As DataTable = New DataTable("dtSelParts") Dim column As DataColumn = New DataColumn column.ColumnName = "PartName" column.ColumnName = "PartNumber" column.ColumnName = "Quantity" dtSelParts.Columns.Add(column) For Each row As GridViewRow In MySearch.Rows Dim drSelParts As DataRow drSelParts = dtSelParts.NewRow() For i As Integer = 0 To row.Cells.Count - 1 drSelParts(i) = row.Cells(i).Text Next Next End Sub When I run the partsearch.aspx page, I enter values in the row textbox for parts I want included in the listbox (to be included in quote). However, I receive the error message System.Index.OutOfRangeException: Cannot find column 1 which occurs on the line drSelParts(i) = row.Cells(i).Text. How might I correct the code and resolve the error? Thanks, Sid

• JSTL c:forEach causes @ViewScoped bean to invoke @PostConstruct on every request

  - by Nitesh Panchal

  Hello, Again i see that the @PostConstruct is firing every time even though no binding attribute is used. See this code :- <?xml version='1.0' encoding='UTF-8' ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:c="http://java.sun.com/jsp/jstl/core"> <h:head> <title>Facelet Title</title> </h:head> <h:body> <h:form> <c:forEach var="item" items="#{TestBean.listItems}"> <h:outputText value="#{item}"/> </c:forEach> <h:commandButton value="Click" actionListener="#{TestBean.actionListener}"/> </h:form> </h:body> </html> And this is the simplest possible bean in JSF :- package managedBeans; import java.io.Serializable; import java.util.ArrayList; import java.util.List; import javax.annotation.PostConstruct; import javax.faces.bean.ManagedBean; import javax.faces.bean.ViewScoped; @ManagedBean(name="TestBean") @ViewScoped public class TestBean implements Serializable { private List<String> listItems; public List<String> getListItems() { return listItems; } public void setListItems(List<String> listItems) { this.listItems = listItems; } public TestBean() { } @PostConstruct public void init(){ System.out.println("Post Construct fired!"); listItems = new ArrayList<String>(); listItems.add("Mango"); listItems.add("Apple"); listItems.add("Banana"); } public void actionListener(){ System.out.println("Action Listener fired!"); } } Do you see any behaviour that should cause postconstruct callback to fire each time? I think JSF 2.0 is highly unstable. If it has to fire PostConstruct each and every time what purpose does @ViewScoped serve. Why not to use @RequestScoped only? I thought i have made some mistake in my application. But when i created this simplest possible in JSF, i still get this error. Am i not understanding the scopes of JSF? or are they not testing it properly? Further, if you remove c:forEach and replace it with ui:repeat, then it works fine. Waiting for replies to confirm whether it is bug or it is intentional to stop the programmers from using jstl?

• Avoiding exceptions when uploading files in laravel

  - by occam98

  I've got a file upload field (attachment1) in a form that may or may not have a file uploaded in it when I process the form in laravel. When I'm trying to process the page, this line generates an exception: Input::upload('attachment1',path('storage').'attachments/'.$name); Here is the text of the exception: Message: Call to a member function move() on a non-object it seems that I need to check in advance to see if 'attachment1' has a file, and I found that the function Input::has_file('attachment1') is supposed to tell me whether or not 'attachment1' has a file, but even when I submit an empty form, it returns true. Also, from reading documentation, it seems that Input::upload is supposed to just return false when trying to upload a non-existant file, so why does it produce this exception instead, and how can I fix it?

• How to make a loop over all keys of a HashMap?

  - by Roman

  I try to do it in the following way: public String getValue(String service, String parameter) { String inputKey = service + ":" + parameter; Set keys = name2value.keySet(); Iterator itr = keys.iterator(); while (itr.hasNext()) { if (inputKey.equal(itr.next())) { return name2value.get(inputKey); } return ""; } } And I get an error message: cannot find symbol method.equal(java.lang.Object). I think it is because itr.next() is not considered as a string. How can I solve this problem? I tried to replace Set keys by Set<String> keys. It did not help.

• Cannot Debug Unmanaged Dll from C#

  - by JustSmith

  I have a DLL that was written in C++ and called from a C# application. The DLL is unmanaged code. If I copy the DLL and its .pdb files with a post build event to the C# app's debug execution dir I still can't hit any break points I put into the DLL code. The break point has a message attached to it saying that "no symbols have been loaded for this document". What else do I have to do to get the debugging in the dll source? I have "Tools-Options-Debugging-General-Enable only my code" Disabled. The DLL is being compiled with "Runtime tracking and disable optimizations (/ASSEMBLYDEBUG)" and Generate Debug Info to "Yes (/DEBUG)"

• ActionScript: Type coercion problem with BlazeDS/AMF and class interfaces

  - by mike

  Hi, I've got a problem with type coercion in a Java/Hibernate/BlazeDS/Flex-Setup. First of all, my classes look like this: --- JAVA --- Interface I (Abstract) Class A implements I Class B extends A --- ActionScript --- Interface I Class A implements I Class B extends A I got RemoteClass-Meta-Tags in all ActionScript-Classes/Interfaces I, A and B. Package structure and Class/Interface names are exactly the same. Now here's the problem: My Java Service successfully retrieves objects of class B from my database via Hibernate. I got another class C which has a member property of interface type I, so it should be possible to assign an object of type B. But for some reason i get the following error message: TypeError: Error #1034: cannot convert Object@28b44a89 to package.name.I I checked the Java object type in the service and it is of type B and seems to be totally fine. Why can't the object of type B be assigned to a member variable of type I? This is driving me nuts. Thanks in advance.

• CMake & ExternalProject: Fails to find specific file

  - by Enrico

  Hi, we have some dependency libraries in our repository. The main part is build with cmake. Now the cmake-makefiles shall build the dependency libraries, which do not have a cmake build system. For one specific library there is a "Makefile.squirrel" which should be used. The cmakelists.txt for that library: cmake_minimum_required (VERSION 2.8) include(ExternalProject) ExternalProject_Add(squirrel, SOURCE_DIR "./" UPDATE_COMMAND "" BUILD_IN_SOURCE 1 CONFIGURE_COMMAND "" BUILD_COMMAND "make -f ${CMAKE_CURRENT_SOURCE_DIR}/Makefile.squirrel" INSTALL_COMMAND "" ) However, when running make I get an error message: [ 93%] Performing build step for 'squirrel,' /bin/sh: make -f /home/enrico/projekte/projectname/dependencies/SQUIRREL2/Makefile.squirrel: not found make[2]: *** [dependencies/SQUIRREL2/squirrel,-prefix/src/squirrel,-stamp/squirrel,-build] Error 127 make[1]: *** [dependencies/SQUIRREL2/CMakeFiles/squirrel,.dir/all] Error 2 make: *** [all] Error 2 ls -lA on /home/enrico/projekte/projectname/dependencies/SQUIRREL2/Makefile.squirrel shows that the file exists.
