  • How easy would it be to refactor a small JSP/Servlet/JDBC project to SpringMVC/Hibernate

    - by John
    With reference to this post, I am considering starting a new web-based Java project. Since I don't know Spring/Hibernate I was concerned if it's a bad plan to start learning them while creating a new project, especially since it will slow down the early development. One idea I had was to write a prototype using tech I do know, namely JSP/Servlets/JDBC, since I can get this running much quicker with my current knowledge. I could then throw the whole thing away and start over with Spring, etc, but I'd like to consider how easy it would be to refactor a smallish project from JSP/Servlets/JDB to SpringMVC/Hibernate? My DB could of course be re-used but what about other code... would I expect to save most of it plugged into an MVC framework, or is the paradigm shift big enough this would cause more trouble than it avoids? Please use the other question for more general advice on choosing technologies

  • What tools do you have at your disposal as a manager to promote a way of thinking

    - by John Leidegren
    This question goes beoynd just programming, but I'd like to get some input on this, if that's okay with the community. Preferably from people that do a lot of coding themselves but also manage other people coding. My problem is this. We have all these ideas that we know is good for the overall strategy of the company and the problem is not figuring out what to do, it's to come about this change. Just telling someone to do things differently isn't enough and it's hard to promote a mind set that is shared within all of the company, (this will take time). If I could jump forward I'd like it if we could create a very nurturing company culture that promotes these ideals cross all areas but I'm not sure what tools to use. And by tools I mean anything I'm legally permitted to do. e.g. we could talk about, we could arrange traning sessions, we could spend more time in meeting (talk about it more), we could spend more time designing, we could spend more time pair-programming, we could add/remove incentive or we could encurage more play. Ultimately if we did all of these things what will be the recurring theme that ties this together. I'd like to be able to answer the question -- why should we do things like this? -- and come up with an answer that explains how important it is to think about our ideals from begining to end. I've puposly avoided to talk about or specifics of the situtation becuase I believe that it narrows things down too much. But I guess, by know you either know how to answer this question or you're as confused as I am ;) I'd love to hear from people who had to bring about a change in order to go from chaos to order, or fix something in the organization which wasn't working. And I'd like to hear it from the perspective of the developer and designer. -- or -- You could simply weigh in on what are the most important qualities in an organization encurage or stimulate rigid fun development cycle from start to finish?

  • C++ - Print Out Objects From Set

    - by John Smith
    If I have a C++ set, declaration set personList; with iterator, set::const_iterator location; how can I print out the contents of the set? They are all person objects, and I have overridden the operator<< for Person. The line that errors is: cout << location and it's in a basic for loop. Netbeans gives the following error: proj.cpp:78: error: no match for ‘operator<<’ in ‘std::cout << location’ so it looks like it wants an override for the iterator's <<. Basically, I am taking objects that used to be stored in an array format, but are now in a set. What is the equivalent to cout << array[i] for sets?

  • SQL developer here -- Nesting with select * finicky in Oracle 10g?

    - by John Sullivan
    I am writing a simple diagnostic query I will execute in my Oracle 10g scratchpad. I am trying to do this as part of a step to build the query. In the SQL Scratchpad for Oracle 10g Enterprise Manager Console, this statement runs fine. SELECT * FROM v$session sess, v$sql sql WHERE sql.sql_id(+) = sess.sql_id and sql.sql_text <> ' ' If I try to wrap that up in Select * from () tb2 I get an error, "ORA-00918: Column Ambiguously Defined". I didn't think that could ever happen with this kind of statement so I am a bit confused. select * from (SELECT * FROM v$session sess, v$sql sql WHERE sql.sql_id(+) = sess.sql_id and sql.sql_text <> ' ') tb2 You should always be able to select * from the result set of another select * statement using this structure as far as I'm aware... right? Is Oracle/10g/the scratchpad trying to force me to accept a certain syntactic structure to prevent excessive nesting? Is this a bug in scratchpad or something about how oracle works?

  • Java: pass an event to another component

    - by John
    Sorry I don't know if this is very clear, but I'm pretty new to Java. So I have a JFrame with a BorderLayout containing a JPanel and a JButton. What I want to do is when something happens in my JPanel, I want for example change the text of the JButton, or enable/disable it. How would I do that? How can I access the JButton from the JPanel? I know some ways of doing it but I don't think they're the best way to do it. What would be the best way to do this? Thanks in advance

  • Can a custom MFC window/dialog be a template class?

    - by John
    There's a bunch of special macros that MFC uses when creating dialogs, and in my quick tests I'm getting weird errors trying to compile a template dialog class. Is this likely to be a big pain to achieve? Here's what I tried: MyDlg.h template <class W> class CMyDlg : public CDialog { typedef CDialog super; DECLARE_DYNAMIC(CMyDlg <W>) public: CMyDlg (CWnd* pParent); // standard constructor virtual ~CMyDlg (); // Dialog Data enum { IDD = IDD_MYDLG }; protected: virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support DECLARE_MESSAGE_MAP() private: W *m_pWidget; //W will always be a CDialog }; IMPLEMENT_DYNAMIC(CMyDlg<W>, super) <------------------- template <class W> CMyDlg<W>::CMyDlg(CWnd* pParent) : super(CMyDlg::IDD, pParent) { m_pWidget = new W(this); } I get a whole bunch of errors but main one appears to be: error C2955: 'CMyDlg' : use of class template requires template argument list I tried using some specialised template versions of macros but it doesn't help much, other errors change but this one remains. Note my code is all in one file, since C++ templates don't like .h/.cpp like normal.

  • How do I use grep to extract a specific field value from lines

    - by Stormshadow
    I have lines in a file which look like the following ....... DisplayName="john" .......... where .... represents variable number of other fields. Using the following grep command, I am able to extract all the lines which have a valid 'DisplayName' field grep DisplayName="[0-9A-Za-z[:space:]]*" e:\test However, I wish to extract just the name (ie "john") from each line instead of the whole line which is returned by grep. I tried pipelining the output to the cut command but it does not accept string delimiters.

  • Why do you have to call URLConnection#getInputStream to be able to write out to URLConnection#getOutputStream?

    - by John
    I'm trying to write out to URLConnection#getOutputStream, however, no data is actually sent until I call URLConnection#getInputStream. Even if I set URLConnnection#doInput to false, it still will not send. Does anyone know why this is? There's nothing in the API documentation that describes this.

  • Use HTTP PUT to create new cache (ehCache) running on the same Tomcat?

    - by socal_javaguy
    I am trying to send a HTTP PUT (in order to create a new cache and populate it with my generated JSON) to ehCache using my webservice which is on the same local tomcat instance. Am new to RESTful Web Services and am using JDK 1.6, Tomcat 7, ehCache, and JSON. I have my POJOs defined like this: Person POJO: import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement public class Person { private String firstName; private String lastName; private List<House> houses; // Getters & Setters } House POJO: import javax.xml.bind.annotation.XmlRootElement; @XmlRootElement public class House { private String address; private String city; private String state; // Getters & Setters } Using a PersonUtil class, I hardcoded the POJOs as follows: public class PersonUtil { public static Person getPerson() { Person person = new Person(); person.setFirstName("John"); person.setLastName("Doe"); List<House> houses = new ArrayList<House>(); House house = new House(); house.setAddress("1234 Elm Street"); house.setCity("Anytown"); house.setState("Maine"); houses.add(house); person.setHouses(houses); return person; } } Am able to create a JSON response per a GET request: @Path("") public class MyWebService{ @GET @Produces(MediaType.APPLICATION_JSON) public Person getPerson() { return PersonUtil.getPerson(); } } When deploying the war to tomcat and pointing the browser to http://localhost:8080/personservice/ Generated JSON: { "firstName" : "John", "lastName" : "Doe", "houses": [ { "address" : "1234 Elmstreet", "city" : "Anytown", "state" : "Maine" } ] } So far, so good, however, I have a different app which is running on the same tomcat instance (and has support for REST): http://localhost:8080/ehcache/rest/ While tomcat is running, I can issue a PUT like this: echo "Hello World" | curl -S -T - http://localhost:8080/ehcache/rest/hello/1 When I "GET" it like this: curl http://localhost:8080/ehcache/rest/hello/1 Will yield: Hello World What I need to do is create a POST which will put my entire Person generated JSON and create a new cache: http://localhost:8080/ehcache/rest/person And when I do a "GET" on this previous URL, it should look like this: { "firstName" : "John", "lastName" : "Doe", "houses": [ { "address" : "1234 Elmstreet", "city" : "Anytown", "state" : "Maine" } ] } So, far, this is what my PUT looks like: @PUT @Path("/ehcache/rest/person") @Produces(MediaType.APPLICATION_JSON) @Consumes(MediaType.APPLICATION_JSON) public Response createCache() { ResponseBuilder response = Response.ok(PersonUtil.getPerson(), MediaType.APPLICATION_JSON); return response.build(); } Question(s): (1) Is this the correct way to write the PUT? (2) What should I write inside the createCache() method to have it PUT my generated JSON into: http://localhost:8080/ehcache/rest/person (3) What would the command line CURL comment look like to use the PUT? Thanks for taking the time to read this...

  • Efficiently using position to control actions

    - by John Ashmore
    I want to use position (returned from a gridview for e.g.) or a similar numeric integer to do various things, e.g. create a sprite, or in any command that wants something other than a number, e.g. I want to use something like: sprites.add(createSprite(R.drawable.image(position)); , where createSprite creates a sprite using the image supplied, instead of: if (position == 1) {sprites.add(createSprite(R.drawable.image1);} if (position == 2) {sprites.add(createSprite(R.drawable.image2);} ...etc There is an easy solution for strings: Most efficient method to use position to open a .java but what about for situations like this one?

  • Embedded Lua on iPhone. What's new and what does it mean?

    - by John Smith
    Apparently Apple has changed some term in the agreement again. From http://www.appleoutsider.com/2010/06/10/hello-lua/ section 3.3.2 is now Unless otherwise approved by Apple in writing, no interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). Notwithstanding the foregoing, with Apple’s prior written consent, an Application may use embedded interpreted code in a limited way if such use is solely for providing minor features or functionality that are consistent with the intended and advertised purpose of the Application. instead of the original No interpreted code may be downloaded or used in an Application except for code that is interpreted and run by Apple’s Documented APIs and built-in interpreter(s). I am more interested in embedding Lua, but other people have other embeddings they want to make. I am wondering how you ask for permission, and what they mean by the terms "minor features" and "consistent" and how will Apple interpret this section? It seems to have enough loopholes to drive a real firetruck through.

  • WPF WrapPanel - all items should have the same width

    - by John
    I have a ListBox whose ItemsPanel I have replaces with a WrapPanel. The WrapPanel now hosts the databound ListboxItems. Each item has a variable sized text in it, giving each item a different width. However, I want the width to be constant so that all items have the same width as the item with the longest text. Is that possible?

  • How to understand other people's CSS architectures?

    - by John
    I am reasonably good with CSS. However, when working with someone else's CSS, it's difficult for me to see the "bigger picture" in their architecture (but i have no problem when working with a CSS sheet I wrote myself). For example, I have no problems using Firebug to isolate and fix cross browser compatibility issues, or fixing a floating issue, or changing the height on a particular element. But if I'm asked to do something drastic such as, "I want the right sidebars of pages A, B, C and D to have a red border. I want the right side bars of pages E, F and G to have a blue border if and only if the user mouses over", then it takes me time a long time to map out all the CSS inheritance rules to see the "bigger picture". For some reason, I don't encounter the same difficulty with backend code. After a quick debriefing of how a feature works, and a quick inspection of the controller and model code, I will feel comfortable with the architecture. I will think, "it's reasonable to assume that there will be an Employee class that inherits from the Person Class that's used by a Department controller". If I discover inconvenient details that aren't consistent with overall architectural style, I am confident that I can hammer things back in place. With someone else's CSS work, it's much harder for me to see the "relationships" between different classes, and when and how the classes are used. When there are many inheritance rules, I feel overwhelmed. I'm having trouble articulating my question and issues... All I want to know is, why is it so much harder for me to see the bigger picture in someone else's CSS architecture than compared to someone else's business logic layer? **Does it have any thing to do with CSS being a relatively new technology, and there aren't many popular design patterns?

  • how to define div or table cell height depending on the height of other divs or cells

    - by John
    I want to have a web page that contains 3 parts: A header at the top of the page , a footer (both of which having specific height in px)and the main part of the page which should be a div or table cell with the appropriate height attribute in order to take all the available space between them. I want the page to take 100% of the browser window height, trying to avoid scrollbars. The problems I have are the following: USING DIVs a) If I set the maindiv height to 100%, the page overflows and I get a vertical scrolbar. (the maindiv's height is set to the 100% of the browser window) <!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"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <style type="text/css"> <!-- body, html{ height: 100%; max-height:100%; width: 100%; margin:0; padding:0; } div{padding:0;margin:0;} #containerdiv{height:100%;width:100%;background-color:#FF9;border:0;} #headerdiv{height:150px;width:100%;background-color:#0F0;border:0;} #footerdiv{height:50px;width:100%;background-color:#00F;border:0; } #maindiv{ background-color:#F00; height:100%; } div{border:#000 medium solid;border:0;} </style> <body> <div id="containerdiv"> <div id="headerdiv">headerdiv</div> <div id="maindiv">maindiv</div> <div id="footerdiv">footerdiv</div> </div> </body> </html> b) If I set the maindiv height to auto, the maindiv height is depending on it's content, which is not what I want. USING tables a) If I set the main cell height to 100% it works fine with Firefox but in Internet Explorer 8 I get a vertical scrollbar (you can use the next code block using th style="height:100%" instead of "auto" to see this.) b) If I set the main cell to auto it seems to be working both in IE and FF but then I have the problem that anything I put inside the maincell (table or div) cannot get maincell's full height in IE. <!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"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> </head> <style type="text/css"> <!-- body, html, table{ height: 100%; width: 100%; margin:0; padding:0; } table{border:#000 0px solid} </style> <body> <table style="background:#063" cellpadding="0" cellspacing="0" border="0"> <tr><th style="height:150px;background-color:#FF0"></th></tr> <tr> <th style="height:auto"><table style="background:#0FF;" cellpadding="0" cellspacing="0" border="0"><tr><th style="height:auto">nested cell</th></tr></table> </th> </tr> <tr><th style="height:50px;background-color:#FF0"></th></tr> </table> </body> </html> </html> Any ideas? Maybe there is an easier way to define the size of the main part of the page in px using javascript? (my javascript skills are pretty poor so any help with this is welcome!)

  • Java 7 New Features

    - by John W.
    I have done some good reading on the new java.util.concurrent features being introduced with the java 7 release. For instance, Phaser, TransferQueue and the more exciting Fork Join Framework. I recently saw a power point made by Josh Bloch about even more features that are going to be introduced however that link has been lost. For example I remember one change is being able to build a Map the same way you can build an array for: Map myMap = {"1,Dog","2,Cat"}; and so forth (this may not be 100% correct but the idea is there) Does anyone know of a list or just can name some new things to look forward to? Note: I did see a question asked http://stackoverflow.com/questions/213958/new-features-in-java-7 however it was asked ~2 years ago and I am sure the list of updates are more concrete. Thanks!

  • ASP.net MVC support for URL's with hyphens

    - by John
    Is there an easy way to get the MvcRouteHandler to convert all hyphens in the action and controller sections of an incoming URL to underscores as hyphens are not supported in method or class names. This would be so that I could support such structures as sample.com/test-page/edit-details mapping to Action edit_details and Controller test_pagecontroller while continuing to use MapRoute method. I understand I can specify an action name attribute and support hyphens in controller names which out manually adding routes to achieve this however I am looking for an automated way so save errors when adding new controllers and actions.

  • How can I detect when the .NET Framework feature is "turned off" in Windows 7 / Vista?

    - by John Myczek
    My application requires the .NET Framework version 3.5. I recently ran into a customer that had the .NET Framework installed but turned off on Windows Vista (also applies to Windows 7). In this case, my installer (InstallShield 2009) does not prompt the user to install the Framework (because it is already installed) and when my application runs it crashes immediately. I tried another .NET application and it also crashes immediately. Is there any way to detect this situation and handle it more gracefully? Just detecting this during install is not ideal since the .NET Framework can be turned off at any time. Ideally, the application would be able to check and display a friendly message to the user telling them they need to turn on the .NET Framework. EDIT: "Turning off" the .NET Framework in Windows Vista or Windows 7 is not the same as uninstalling it. The Framework can be simply turned back on without reinstalling: http://windows.microsoft.com/en-US/windows-vista/Turn-Windows-features-on-or-off

  • Web app implementation question.

    - by John Berryman
    I would like to create a web app similar to Stack Overflow in that the users will have different "point" levels and that their capabilities within the web app will be different based upon their point level. Question: How can this best be implemented? How can it be implemented in a way that is un-hackable (i.e. accessing capabilities that should not be available)? I figure there are two ways to do this: server-side and client-side. For the server-side solution, for each page request you check who the user is and have the CGI rewrite the page so that the client only gets a web page with the intended capabilities. For the client-side solution, the server gives the client the fully capable app and it is the client's job to check the point level and to handicap the app appropriately. It seems like the client-side solution would be easier on the server, (which is really important for my app), but more susceptible to someone hacking and using capabilities unwarranted by their point level.
