  • Struts for IBM Application Server Toolkit

    - by Timbuck
    I'm looking to build a Struts 1.2.x application for Websphere, using IBM's Application Server Toolkit. Are there any plugins available for this toolkit (it is a version of Eclipse) that are known to help with this type of development? I am new to Struts so I will also be learning about the technology as I go along, but I want to make it as painless as possible. A web search has only brought up things such as "MyEclipse", which I can't use in the corporate environment.

  • how to implement this observer pattern?

    - by lethal
    Hello. I have 4 classes, that describe state diagram. Node, Edge, ComponentOfNode, ComponentOfEdge. ComponentOfEdge compounds from ComponentsOfNode. Node can have 0..n outgoing edges. Edge can have only 2 nodes. Edge should be able to offer ComponentOfNode, but only from nodes that Edge has, in form ComponentOfEdge. The user can change ComponentsOfNode. I need this change spreads to all Edge. Hw to do it? I expect the observer should be used. Can you give me example in pseudocode please?

  • Check if edit is valid for database ms-access

    - by twodayslate
    I want to be able to check if I can edit a cell in a database with a new object Example method declaration: something.isValid(Object newObject, row, column); Example cases: If the editing cell stores an Number and I give it a String, the method will return false... If the editing cell has to be different than every other entry and the new object is the same as something else, the method will also return false.... My main goal... I want to check a whole row, and if everything is valid, I will edit the whole row. Right now, the only way I can find out if I can actually edit something is by actually editing it and seeing if I get an error.

  • How do I connect StaticListableBeanFactory with ClassPathXmlApplicationContext?

    - by Aaron Digulla
    In the setup of my test cases, I have this code: ApplicationContext context = new ClassPathXmlApplicationContext( "spring/common.xml" ); StaticListableBeanFactory testBeanFactory = new StaticListableBeanFactory(); How do I connect the two in such a way that tests can register beans in the testBeanFactory during setup and the rest of the application uses them instead of the ones defined in common.xml? Note: I need to mix a static (common.xml) and a dynamic configuration. I can't use XML for the latter because that would mean to write 1000 XML files.

  • Chat client with GWT

    - by user284016
    What would be the best way to create a JS chat client with GWT? The bit that I'm having trouble with is the persistence and transfer of the messages. Should I store the messages in a DB and check the db for new messages? Is there a much better way to do this?

  • Complete list of Fonts which support

    - by Yan Cheng CHEOK
    Currently, if I change the locale setting of my application by Locale.setDefault(Locale.ENGLISH); Locale.setDefault(Locale.SIMPLIFIED_CHINESE); What I understand from this JFreeChart forum is that, I am not using correct font. Once you get the reference of the LegentTitle, you can set it to any font. Apparently, JFreeChart's default is "Tahoma" and it doesn't support Chinese characters. May I know, how I can programmatic determine, as list of available Fonts in my system, which support Chinese? I can hard code it to Serif (It fully support Chinese, doesn't it?), its look n feel doesn't looks good to me. I would like to have more choices.

  • Passing.getText() String to another class

    - by DanMc
    I'm currently working on a first year university project and I have a problem, although I doubt it's a very complicated one, but I've been searching and I just can't find a suitable answer to it. The problem concerns two classes. A gui class (class1) and another class (class2). I have a JTextField in class1 and am trying to pass through the .getText() value to class2 and store it in a String type variable. The current code I'm trying to achieve this with is the following: (Class1) private JTextField textField = new JTextField("Something"); ... public String getTextFieldString() { return textField.getText(); } (Class2) private c1 Class1 = new Class1(); private String s = new String(); ... s = c1.getTextFieldString(); I'm pretty new to coding, I've read that maybe I need to pass through an argument somewhere and I assume that's because textField is not static in itself, it changes when somebody enters a new value. (sorry for stating the obvious there.) Anyway, help is appreciated. Thanks a lot!

  • How to send HTML as GET-Request parameter?

    - by Mork0075
    I would like to send a html string with a GET request like this with Apaches HttpClient: http://sample.com/?html=<html><head>... This doesnt work at the moment, i think its an encoding problem. Do you have any ideas how to do that? method.setQueryString(new NameValuePair[] {new NameValuePair("report", "<html>....")}); client.executeMethod(method) This fails with org.apache.commons.httpclient.NoHttpResponseException: The server localhost failed to respond. If i replace "<html>" by "test.." it works fine. EDIT It seams to be a problem of URL length after encoding, the server doesnt except such long URls. Sending it as POST solves the problem.

  • Extract elements from list based on object property type

    - by Dustin Digmann
    Often, I have a list of objects. Each object has properties. I want to extract a subset of the list where a specific property has a predefined value. Example: I have a list of User objects. A User has a homeTown. I want to extract all users from my list with "Springfield" as their homeTown. I normally see this accomplished as follows: List users = getTheUsers(); List returnList = new ArrayList(); for (User user: users) { if ("springfield".equalsIgnoreCase(user.getHomeTown()) returnList.add(user); } I am not particularly satisfied with this solution. Yes, it works, but it seems so slow. There must be a non-linear solution. Suggestions?

  • Does thread pool size keep growing for scheduledthreadpoolexecutor?

    - by Sourajit Basak
    Imagine a situation where tasks are being added to scheduledthreadpoolexecutor. Each of these tasks will keep on running at different periodic intervals. Although all such tasks will not be running at the same time because each is set at different intervals, there may be a situation where a high number of threads are competing for execution. Is there any restriction on total number of threads ? It seems there is a restriction on the total number of idle threads. And does this concept of idle thread imply that long running tasks (thread) may be destroyed and recreated when needed ?

There are multiple items starting with the same letter Thanks

  • How can I get an error or a warning from a PreparedStatement?

    - by Geo
    I had an update like this: update table set col1=?,col2=?,col3=? where col4=?; and I filled it up like this: statement.setString(1,"some_value"); statement.setString(2,"some_value"); statement.setString(3,"some_value"); and I forgot to add a fourth value.I did a executeUpdate and of course nothing happened to the database. I spent about 1 hour debugging it, to see where it goes wrong. I then modified my code to print the SQLWarning object returned by the getWarnings method. It always returned null. I even modified the code to the buggy state it was, before I set the fourth parameter, and still no warning. Does anyone know how one can get an error/warning? If it matters, my Connection is set to autoCommit.

  • How to handle dependency files in a cross-platform manner?

    - by Brian Knoblauch
    I'm working on updating an old app. It has some dependency files that live in the same directory as the app. Obviously this broke when Windows Vista came out (since it violates the API and Vista/7 now enforce that (XP didn't)). Ideally, I'd like to avoid hardcoding anything into the app for just Windows. I can live with that if I have to though. I've already been down that path with pulling the APPDATA and LOCALAPPDATA environment variables, but that doesn't help any since they just give you the current user area... I need these to live somewhere accessible for all users, and I'd like to obey the Windows API expectations that they go into the all user appdata area. Suggestions?

  • JSP Component Creation

    - by jboyd
    When creating JSP pages one thing that I'd often like is the ability to do something like this: <jsp:include page="fancystoryrenderer.jsp" value="${aStoryObjectInMyModel}/> ... fancystoryrenderer.jsp <div id="fancymainbody"> ... ${theStory.title} ... </div> The main important characteristics of this is that I can reuse the same component on the same JSP page in different places without having to copy paste the component and give the story variables different names, notice that the story is called "theStory" in the JSP and not "aStoryObjectInMyModel", the linkage between our model has been broken by the view, which is a good thing in this case How do you do this?
