  • javax.servlet import cannot be resolved after moving web servlet

    - by Michael Kjörling
    I have written a small web servlet to run under Tomcat, using Eclipse Helios. In its old, non-source-controlled location, everything was fine, but now I need to add this to our source control system. Moving the old files out of the way, creating a new workspace, setting up the server connection and copying and importing the existing projects into the new workspace all worked fine once I figured out how to do it, but I can't get the servlet to build. Instead, I get a whole bunch of cannot be resolved to a type errors talking about various servlet class types; HttpServlet, HttpServletRequest, ServletException, etc. Another error that is almost certainly related is The import javax.servlet cannot be resolved. I am obviously missing something very basic, but I'm new to this (and not having the terminology really down pat probably doesn't help me Google for an answer). Any suggestions as to what I might be missing would be greatly appreciated.

  • Error Downloading Metadata from ASMX Service

    - by michael.lukatchik
    It should be possible (and it looks like it is), but assume I have the following functions in my ASMX web service: [WebMethod(MessageName = "CreateExternalRpt1")] public bool CreateExternalRpt(int iProductId, int iOrderProductId, DateTime dtReportTime, string strReportTitle, string strReportCategory, string strReportPrintType, out string strSnapshot, string strApplicantFirst, string strApplicantLast, string strApplicantMiddle, string strOwnerLast, string strOwnerMiddle, string strOwnerFirst, bool blnCurrentReport, int iOrderId, bool blnFlag, string strCustomerId, string strUserId) { … } [WebMethod(MessageName = "CreateExternalRpt2")] public bool CreateExternalRpt(int iProductId, int iOrderProductId, DateTime dtReportTime, string strReportTitle, string strReportCategory, string strReportPrintType, string strReportSnapshot, string strApplicantFirst, string strApplicantLast, string strApplicantMiddle, string strOwnerLast, string strOwnerMiddle, string strOwnerFirst, bool blnCurrentReport, int iOrderId, bool blnFlag) { … } With both of these functions defined in my web service, my .NET client app can’t download the metadata and instead throws a generic error message “There was an error downloading…”. With one of the above methods removed, the .NET client app can successfully download the metadata. I’ve read that by decorating the WebMethod with a unique name, both functions should be exposed in the service metadata. This isn’t working. What am I missing?

  • Check for column name in a SqlDataReader object

    - by Michael Kniskern
    How do I check to see if a column exists in a SqlDataReader object? In my data access layer, I have create a method that builds the same object for multiple stored procedures calls. One of the stored procedures has an additional column that is not used by the other stored procedures. I want to modified the method to accommodate for every scenario. My application is written in C#.

  • Why does instanceof seem to work in a static generic function sometimes?

    - by michael
    Greetings. This is my first post in this site. I thought that because of type erasure, one could not expect the following code to compile, and indeed, it did not compile on an earlier version of Eclipse. My understanding was that instanceof was a run-time operator and could not know about the generic type which would be, by run-time, compiled away: public static <E extends Comparable<? super E>> void SampleForQuestion(E e) { if ( !(e instanceof String) ) System.out.println("I am not a String"); else System.out.println("I am a String"); } However, I was surprised to see that one of your threads actually included some code like this in an answer, and my latest Eclipse (Galileo on Windows with JVM 1.6 rev 20) is perfectly happy with it -- and it works, too. (I did notice that someone said it worked on Eclipse but not in another IDE/JDK in that thread, but don't remember the specifics.) Can someone explain why it works, and more importantly, because I have to guide my students, whether it should be expected to work in the future. Thank you. (I hope the code formatting comes through correctly - it looks indented correctly from my perspective and there are no tabs.)

  • Problem passing a reference as a named parameter to a variadic function

    - by Michael Mrozek
    I'm having problems in Visual Studio 2003 with the following: void foo(const char*& str, ...) { va_list args; va_start(args, str); const char* foo; while((foo = va_arg(args, const char*)) != NULL) { printf("%s\n", foo); } } When I call it: const char* one = "one"; foo(one, "two", "three", NULL); I get: Access violation reading location 0xcccccccc on the printf() line -- va_arg() returned 0xcccccccc. I finally discovered it's the first parameter being a reference that breaks it -- if I make it a normal char* everything is fine. It doesn't seem to matter what the type is; being a reference causes it to fail at runtime. Is this a known problem with VS2003, or is there some way in which that's legal behavior? It doesn't happen in GCC; I haven't tested with newer Visual Studios to see if the behavior goes away

  • How to Compute a Database Column in .NET

    - by Michael
    I have a Database named CarsType.accdb there are four fields in the data base Item_Name, Item_Num, Item_Qty, Item_Cost. I am able to get the database to display my data in VisualBasic but I am not sure how to get the total cost to appear in my label (lblTotalCost). I prefer doing it in VB versus writing in my access program. All I am wanting to do it multiply item_qty * Item_Cost How would I go about doing that?

  • SqlCE DB occasionally freezes on one handheld, not another

    - by Michael
    I have two types of custom handhelds which are similar, but slightly different, each running the same WinForm application and a WinCE database: Type 1: WinCE 4.2, 400 mhz, 93244 kb Type 2: WinCE 5.0, 520 mhz, 84208 kb Type 1 will happily proceed through a large batch db operation (initiated) by the app, by Type 2 will consistently begin c-r-a-w-l-i-n-g (for several to many cycles) at around the 200 cycle mark. As several points it will begin running normally and then crawl again. The app does several db op's (inserts, updates and selects, no deletes). To simplify my situation, I've built a small test app which essentially does this: command_s.CommandText = "select dvr from vr where vid = 2211250"; command_u.CommandText = "update pvr set LocationID=81 where Status='OK' and vri = 27861"; while(going) { command_s.ExecuteScalar(); command_u.ExecuteNonQuery(); } and set it off running on the two units side by side. Sure enough, the slower (400 mhz) unit is outpacing the faster (520 mhz) unit (it's about 5000 cycles ahead right now) and I can see noticable pauses on the 520 mhz unit. What is causing this?

  • Refactoring - Speed increase

    - by Michael G
    How can I make this function more efficient. It's currently running at 6 - 45 seconds. I've ran dotTrace profiler on this specific method, and it's total time is anywhere between 6,000ms to 45,000ms. The majority of the time is spent on the "MoveNext" and "GetEnumerator" calls. and example of the times are 71.55% CreateTableFromReportDataColumns - 18, 533* ms - 190 calls -- 55.71% MoveNext - 14,422ms - 10,775 calls What can I do to speed this method up? it gets called a lot, and the seconds add up: private static DataTable CreateTableFromReportDataColumns(Report report) { DataTable table = new DataTable(); HashSet<String> colsToAdd = new HashSet<String> { "DataStream" }; foreach (ReportData reportData in report.ReportDatas) { IEnumerable<string> cols = reportData.ReportDataColumns.Where(c => !String.IsNullOrEmpty(c.Name)).Select(x => x.Name).Distinct(); foreach (var s in cols) { if (!String.IsNullOrEmpty(s)) colsToAdd.Add(s); } } foreach (string col in colsToAdd) { table.Columns.Add(col); } return table; }

  • N-gram split function for string similarity comparison

    - by Michael
    As part of excersise to better understand F# which I am currently learning , I wrote function to split given string into n-grams. 1) I would like to receive feedback about my function : can this be written simpler or in more efficient way? 2) My overall goal is to write function that returns string similarity (on 0.0 .. 1.0 scale) based on n-gram similarity; Does this approach works well for short strings comparisons , or can this method reliably be used to compare large strings (like articles for example). 3) I am aware of the fact that n-gram comparisons ignore context of two strings. What method would you suggest to accomplish my goal? //s:string - target string to split into n-grams //n:int - n-gram size to split string into let ngram_split (s:string, n:int) = let ngram_count = s.Length - (s.Length % n) let ngram_list = List.init ngram_count (fun i -> if( i + n >= s.Length ) then s.Substring(i,s.Length - i) + String.init ((i + n) - s.Length) (fun i -> "#") else s.Substring(i,n) ) let ngram_array_unique = ngram_list |> Seq.ofList |> Seq.distinct |> Array.ofSeq //produce tuples of ngrams (ngram string,how much occurrences in original string) Seq.init ngram_array_unique.Length (fun i -> (ngram_array_unique.[i], ngram_list |> List.filter(fun item -> item = ngram_array_unique.[i]) |> List.length) )

  • popup panel that docks to the bottom of the screen

    - by Michael Wiles
    How do I create a pop panel that docks to the bottom of the screen... The way that I'm doing this is by setting the styling as such: bottom: 10px; position: absolute; This will always set the panel to 10 px from the bottom of the browser window. The problem is that gwt (or gwtp for that matter) is insisting on setting the right and the top of the panel and thus overriding my styling. If I use chrome's element explorer and disable the right and top style rules I get the correct behaviour so one way of doing it is somehow disabling gwt setting of the location of the panel on the screen...?

  • How to apply patterns when not all team members can follow them

    - by michael moore
    We're going to start a new huge project and while it's in the process of architecting the system, I have certain doubts whether I can apply patterns and be sure they won't be violated by team members. The problem is, not all team members have enough skills to develop asp.net apps let's say using MVP pattern. So maybe this question is addressed to Team leads, or experienced devs. Did you dealt with this kind of situation, and if so what was your solution. I was thinking to create the core by myself, and let 'em start building upon that core, however I'm not sure it will work out.

  • Incorrect emacs indentation in a C++ class with DLL export specification

    - by Michael Daum
    I often write classes with a DLL export/import specification, but this seems to confuse emacs' syntax parser. I end up with something like: class myDllSpec Foo { public: Foo( void ); }; Notice that the "public:" access spec is indented incorrectly, as well as everything that follows it. When I ask emacs to describe the syntax at the beginning of the line containing public, I get a return of: ((label 352)) If I remove the myDllSpec, the indentation is correct, and emacs tells me that the syntax there is: ((inclass 352) (access-label 352)) Which seems correct and reasonable. So I conclude that the syntax parser is not able to handle the DLL export spec, and that this is what's causing my indentation trouble. Unfortunately, I don't know how to teach the parser about my labels. Seems that this is pretty common practice, so I'm hoping there's a way around it.

  • How to extract ALL typedefs and structs and unions from c++ source

    - by Michael Wells
    I have inherited a Visual Studio project that contains hundreds of files. I would like to extract all the typedefs, structs and unions from each .h/.cpp file and put the results in a file). Each typdef/struct/union should be on one line in the results file. This would make sorting much easier. typdef int myType; struct myFirstStruct { char a; int b;...}; union Part_Number_Serial_Number_Part_2_Response_Message_Type {struct{Message_Response_Head_Type Head; Part_Num_Serial_Num_Part_2_Report_Array Part_2_Report; Message_Tail_Type Tail;} Data; BYTE byData[140];}myUnion; struct { bool c; int d;...}mySecondStruct; My problem is, I do not know what to look for (grammar of typedef/structs/unions) using a regular expression. I cannot believe that nobody has done this before (I googled and have not found anything on this). Does anyone know the regular expressions for these? (Note some are commented out using // others /* */) Or a tool to accomplish this. Edit: I am toying with the idea of autogenerating source code and/or dialogs for modifying messages that use the underlying typedef/struct/union. I was going to use the output to generate an XML file that could be used for this reason. The source for these are in C/C++ and used in almost all my projects. These projects are usually NOT in C/C++. By using the XML version I would only need to update/add the typedef/struct/union only in one place and all the projects would be able to autogen the source and/or dialogs.

  • Sharepoint 2010, get the Distinct Values of a User Profile Property?

    - by Michael Stum
    Is there any way in SharePoint 2010 to get the Distinct values of a property accross all users? For example, I want a list of all Departments in the Profile Store. In SQL I can do SELECT DISTINCT(PropertyVal) FROM [ProfileDB].[dbo].[UserProfileValue] WHERE PropertyID = 14 but accessing the SQL Database is a big no-no of course, so I wonder if there is something in the object model? Note that accessing the User Information List on an SPSite is not good enough, as only a fraction of all users is in that list. I want to get it directly from the Profile Store.

  • Is There a Good Pattern for Creating a Unique Id based on a Type?

    - by Michael Kelley
    I have a template that creates a unique identifier for each type it is instanced. Here's a streamlined version of the template: template <typename T> class arType { static const arType Id; // this will be unique for every instantiation of arType<>. } // Address of Id is used for identification. #define PA_TYPE_TAG(T) (&arType<T >::Id) This works when you have an executable made purely of static libraries. Unfortunately we're moving to an executable made up of dlls. Each dlls could potentially have its own copy of Id for a type. One obvious solution is to explicitly instantiate all instances of arType. Unfortunately this is cumbersome, and I'd like to ask if anyone can propose a better solution?
