  • Why would JSP tags appear in HTML source code?

    - by Michael
    I'm a front-end web developer at a company using Java on their server. As a front-end developer, I'm concerned with the HTML structure that the server produces, but I don't have control over anything our back-end team produces. Rather than ask someone on that team, I would like to gather knowledge from the Stackoverflow community so I can communicate intelligently with the back-end team. So, I am curious as to what would cause certain JSP tags to appear in the rendered HTML that is sent to the browser. We have tags in our HTML source such as: <flow:fileRef id="vfileColor" fileId="vfile.color"/> <flow:fileRef id="StyleDir" fileId="StyleDir"/> <flow:fileRef id="vfileStylesheet" fileId="vfile.stylesheet"/> I am more interested in knowing why these appear, not as much about what they do. Is there a server setting for Tomcat/Apache/etc. that would hide these tags from the browser? Any information would be helpful. Thanks in advance.

  • The member [class] has no supported translation to SQL

    - by Code Sherpa
    Hi, I am getting the following error: Error Message:The member 'Company.ProductCore.Core.Domain.Account.Email' has no supported translation to SQL. My method looks like this: public Account GetAccountByEmail(string email) { Account account; using (WorkbookDataContext dc = _conn.GetContext()) { account = ( from a in dc.Accounts join em in dc.Emails on a.AccountId equals em.AccountId where a.Email.EmailAddress == email select a).FirstOrDefault(); } return account; } My Account class has a getter / setter that exposes Email: public Email Email { get { return _email; } set { _email = value; } } And my Email is a LINQ object. I have a feeling that the problem is that I am using a LINQ object for me Email property? I am new to LINQ and am not really sure why this is happening. Help appreciated, thanks...

  • How to code the set method of a Map with another Map as value?

    - by Nazgulled
    I normally do this to set a new Map to a private variable: public static void setListaClausulas(Map<String, Clausula> nvLista) { listaClausulas = new TreeMap<String, Clausula>(nvLista); } I suppose this is ok to set a new copy of the nvLista and all it's members and not a reference, is it? But now I have a Map inside another Map and I'm doing this: public static void setListaClausulas(Map<String, Map<String, Clausula>> nvLista) { listaClausulas = new TreeMap<String, Map<String, Clausula>>(nvLista); } Is this the correct way to do it or do you recommend something else? What I want is to set a new copy of nvLista (and all it's elements) and not copy just the reference.

  • How do I unpack bits from a structure's stream_data in c code?

    - by Chelp
    Ex. typedef struct { bool streamValid; dword dateTime; dword timeStamp; stream_data[800]; } RadioDataA; Ex. Where stream_data[800] contains: **Variable** **Length (in bits)** packetID 8 packetL 8 versionMajor 4 versionMinor 4 radioID 8 etc.. I need to write: void unpackData(radioDataA *streamData, MA_DataA *maData) { //unpack streamData (from above) & put some of the data into maData //How do I read in bits of data? I know it's by groups of 8 but I don't understand how. //MAData is also a struct. }

  • Sharing assembly code between WPF, Silverlight and Windows Phone: quite impractical for big projects !

    - by user310291
    It is said here: http://blogs.msdn.com/b/mikeormond/archive/2010/12/09/writing-cross-platform-xaml-applications.aspx Within Visual Studio, if you add files to the project via “Add Existing Item”, and select the “Add As Link” option you can work on the same file from multiple projects. Oh my I'm on a project which have multiple countries, brands, components layers and each time I will add a file you want me to "Add as Link" ? This is a nightmare maintenance ! Is there any other solutions ?

  • Is this Leftist Tree piece of code from Wikipedia correct?

    - by they changed my name
    Link public Node merge(Node x, Node y) { if(x == null) return y; if(y == null) return x; // if this was a max height biased leftist tree, then the // next line would be: if(x.element < y.element) if(x.element.compareTo(y.element) > 0) { // x.element > y.element Node temp = x; x = y; y = temp; } x.rightChild = merge(x.rightChild, y); if(x.leftChild == null) { // left child doesn't exist, so move right child to the left side x.leftChild = x.rightChild; x.rightChild = null; x.s = 1; } else { // left child does exist, so compare s-values if(x.leftChild.s < x.rightChild.s) { Node temp = x.leftChild; x.leftChild = x.rightChild; x.rightChild = temp; } // since we know the right child has the lower s-value, we can just // add one to its s-value x.s = x.rightChild.s + 1; } return x; } What makes me ask this question is: if(x.element.compareTo(y.element) > 0) { // x.element > y.element Node temp = x; x = y; y = temp; } Isn't that just not gonna work, since the references are only switched inside the method?

  • SQLite issues, escaping certain characters...

    - by CODe
    I'm working on my first database application. It is a WinForms application written in C# using a SQLite database. I've come across some problems, when a apostrophe is used, my SQLite query fails. Here is the structure of my queries. string SQL = "UPDATE SUBCONTRACTOR SET JobSite = NULL WHERE JobSite = '" + jobSite + "'"; For instance, if an apostrophe is used in the jobSite var, it offsets the other apostrophes in the command, and fails. So my questions are: 1. How do I escape characters like the apostrophe and semicolon in the above query example? 2. What characters do I need to escape? I know I should escape the apostrophe, what else is dangerous? Thanks for your help!

  • How to strip debug code during compile time in C++?

    - by juvenis
    Say I have a C++ function debugPrint(int foo). How can I most conveniently strip that from release builds? I do not want to surround every call to debugPrint with #ifdefs as it would be really time consuming. On the other hand, I want to be 100% sure that the compiler strips all the calls to that function, and the function itself from release builds. The stripping should happen also, if it's called with a parameter that results from a function call. E.g., debugPrint(getFoo());. In that case I want also the getFoo() call to be stripped. I understand that function inlining could be an option, but inlining is not guaranteed to be supported.
