  • How do I properly display all content in a JTabbedPane?

    - by maleki
    I am nesting a JPanel inside a JTabbedPane. I am having trouble displaying all the content inside of the JTabbedPane. The outside borders of the internal content get chopped off. I am currently not using a Layout Manager for my JTabbedPane or dummy Panel because it stretches my content automatically. How do I add a JPanel inside the JTabbedPane so that I can have an even border around all the content.My attempts to create a dummy panel and setting a border for the inner panel using BorderFactory haven't worked. Is there a convention that I need to know to do this correctly? JTabbedPane tabPane = new JTabbedPane(); GridPane tab1 = new GridPane(); GridPane tab2 = new GridPane(); tabPane.add("My Pieces",tab1); tabPane.add("Opponent Pieces",tab2); public class GridPane extends JPanel { public GridPane() { this.setPreferredSize(new Dimension(400,160)); this.setLayout(new GridLayout(4,10)); this.setComponentOrientation(ComponentOrientation.LEFT_TO_RIGHT); for (int i = 0; i < 4; i++) { for (int j = 0; j < 10; j++) { boardSquares[i][j] = new JPanel(); boardSquaresArr.add(boardSquares[i][j]); this.add(boardSquares[i][j]); } } } }

  • Intersecting boundaries with lucene

    - by Silvio Donnini
    I'm using Lucene, and I'm trying to find a way to index and retrieve documents that have a ranged property. For example I have: Document 1: Price:[30 TO 50] Document 2: Price:[45 TO 60] Document 3: Price:[60 TO 70] And I would like to search for all the documents whose ranges intersect a specific interval, in the above example, if I search for Price in [55 TO 65] I should get Document 2 and Document 3 as results. I don't think NumericRangeQueries alone would do the trick, I need to work on the index with something similar to R-trees, but are they implemented in Lucene? Also, I suppose that what I need should be a subclass of MultiTermQuery, because the query Price in [55 TO 65] has two boundaries, but I don't see anything suitable among MultiTermQuery's subclasses. Any help is appreciated, thanks, Silvio P.S. I'm using Lucene 2.9.0, but I can update to the latest release if needed.

  • How do I create a custom text field in Tapestry5 that renders some Javascript onto the page?

    - by shane87
    I have been trying to create a custom textfield in tapestry which will render some javascript when it gains focus. But I have been having trouble trying to find an example of this. Here is some of the code i have started off with: package asc.components; import org.apache.tapestry5.ComponentResources; import org.apache.tapestry5.Field; import org.apache.tapestry5.annotations.Parameter; import org.apache.tapestry5.ioc.annotations.Inject; import org.apache.tapestry5.services.ComponentDefaultProvider; public class DahserTextField implements Field { @Parameter (defaultPrefix = "literal") private String label; @Inject private ComponentResources resources; @Inject private ComponentDefaultProvider defaultProvider; @Parameter private boolean disabled; @Parameter private boolean required; String defaultLabel(){ return defaultProvider.defaultLabel(resources); } public String getControlName() { return null; } public String getLabel() { return label; } public boolean isDisabled() { return disabled; } public boolean isRequired() { return required; } public String getClientId() { return resources.getId(); } } I have been unsure on what to do next. I do not know what to put into the .tml file. I would be grateful if anyone could help or point me in the right direction.

  • custom tag 'cannot be resolved to a type'

    - by lotus99t
    I have a custom tag, packaged into a library jar that is included in my web apps war file. I get the following error: An error occurred at line: 66 in the jsp file: /WEB-INF/jsp/portlet/portfolio/operations/operationsInfo.jsp org.apache.jsp.tag.meta.form.WidgetFactory_tag cannot be resolved to a type 63: <c:forEach var="fldCfg" items="${config.page.fields}" > 64: <tr> 65: <td><form:Label fld="${fldCfg}"/></td> 66: <td><form:WidgetFactory fld="${fldCfg}" decodesMap="${decodesMap}" command="${operationsInfoBean}" dateFormat="${preferredDateFormat}"/></td> 67: </tr> 68: </c:forEach> 69: </table> But it doesn't seem to complain about Label which is in the same taglib. I've confirmed that the jar is in the war and that the tag file is in the jar and the that the TLD (in META-INF) expressly defines 'WidgetFactory' Why am I getting this error?

  • Is it considered a good/bad practice to configure tomcat for deploying certain apps?

    - by Roman
    Disclaimer: I've never used technique which is described below. That's why there may occur some mistakes or misunderstandings in its description. I heard that some teams (developers) use 'pre-configured' tomcat. As I understand they add different jars to tomcat \lib folder and do something else. Once I've read something about recompilation (or reassembly?) of tomcat for certain needs. Just yesterday I heard a dialog where one developer sayd that his team-mates were not able to deploy the project until he would give them configured tomcat version. So, I wonder, what is it all about and why do they do it? What benefits can they gain from that?

  • Inspect in memory hsqldb while debugging

    - by Albert
    We're using hdsqldb in memory to run junit tests which operate against a database. The db is setup before running each test via a spring configuration. All works fine. Now when a tests fails it can be convinient to be able to inspect the values in the in memory database. Is this possible? If so how? Our url is: jdbc.url=jdbc:hsqldb:mem:testdb;sql.enforce_strict_size=true The database is destroyed after each tests. But when the debugger is running the database should also still be alive. I've tried connecting with the sqldb databaseManager. That works, but I don't see any tables or data. Any help is highly appreciated!

  • Loading a class file immediately AFTER startup

    - by Striker
    We have a few war files deployed inside an ear file. Some of the war files have a class that caches static data from our PLM system in singletons. Since some of the classes take several minutes to load we use the load-on-startup in the web.xml to load them ahead of time. This all works fine until we attempt to re-deploy the application on our production servers. (WebLogic 10.3) We get an exception from our PLM API about a dll already being loaded. Our PLM vendor has confirmed that this is a problem and stated that they don't support using the load-on-startup. This is also a huge problem on our development boxes where we have redeploy the app all the time. Most of us, when we're not working on one of the apps that uses a cache, have them commented out. Obviously we can't do that for the production servers. Right now we transfer the ear to the production server, deploy it in the console, wait for it to crash, shut the app server instance down and then start it up again. We need to find a way around this... One suggestion was to create a servlet that we can call after the server boots that will load the various caches. While this will work I'm looking for something a bit cleaner. Is there anyway to detect once the server started and then fire off the methods? Thanks.

  • Merging two templates in iText

    - by Shaggy Frog
    Let's say I have two PDF templates created with Adobe Acrobat, which are both single-page, 8.5x11 documents. The first template (A.pdf) has content for the top half of the page. The second template (B.pdf) has content for the bottom half of the page. (It just so happens the content in both templates does not "overlap" each other.) I would like to use iText to take these two templates and create a single, "merged" template from it (C.pdf) that is only a single page (with A.pdf's content on the top half and B.pdf's content on the bottom half). (I do not want to "merge" these two files into a 2-page document. I need the final product to be a single page.) I will be running iText in a servlet environment (Tomcat 6) but I don't think that makes a difference to the answer. Is this possible?

  • Pause and Resume AsyncTasks? (Android)

    - by Matt Swanson
    I have an AsyncTask that acts as a countdown timer for my game. When it completes the countdown it displays the out of time end screen and it also updates the timer displayed on the screen. Everything works fine, except I need to be able to pause and resume this when the pause button in the game is pressed. If I cancel it and try to re-execute it, it crashes with an IllegalStateException. If I cancel it and instantiate a new AsyncTask in its place the old one begins to run again and the new one runs at the same time. Is there a way to cancel/pause the timer and restart it using AsyncTasks or is there a different way I should be going about doing this?

  • JMX - MBean automated registration on application deployment

    - by Gadi
    Hi All, I need some direction with JMX and J2EE. I am aware (after few weeks of research) that the JMX specification is missing as far as deployment is concerned. There are few vendor specific implementations for what I am looking for but none are cross vendor. I would like to automate the deployment of MBeans and registration with the Server. I need the server to load and register my MBeand when the application is deployed and remove when the application is un-deployed. I develop with: NetBean 6.7.1, GlassFish 2.1, J2EE5, EJB3 More specific, I need a way to manage timer service runs. My application need to run different archiving agents and batch reporting. I was hoping the JMX will give me remote access to create and manage the timer services and enable the user to create his own schedule. If the JMX is auto registered on application deployment the user can immediately connect and manage the schedule. On the other hand, how can an EJB connect/access an MBean? Many thanks in advance. Gadi.

  • Delete or comment out non-working JUnit tests?

    - by Chris Knight
    I'm currently building a CI build script for a legacy application. There are sporadic JUnit tests available and I will be integrating a JUnit execution of all tests into the CI build. However, I'm wondering what to do with the 100'ish failures I'm encountering in the non-maintained JUnit tests. Do I: 1) Comment them out as they appear to have reasonable, if unmaintained, business logic in them in the hopes that someone eventually uncomments them and fixes them 2) Delete them as its unlikely that anyone will fix them and the commented out code will only be ignored or be clutter for evermore 3) Track down those who have left this mess in my hands and whack them over the heads with the printouts of the code (which due to long-method smell will be sufficently suited to the task) while preaching the benefits of a well maintained and unit tested code base

  • Spring - Transaction Readonly

    - by AAK
    Hello Gurus! Just wanted your expert opinions on declarative transaction management for Spring. Here is my setup - A. DAO Layer is Plain old JDBC using jdbcTemplete (No hibernate etc) B. Service Layer is POJO with declarative trasnactions as follows - save*, readonly=false, rollback for Throwable Things work fine with above setup. However when I say get*, readonly=true I see errors in my log file saying - Database connection cannot be marked as readonly. This happens for all get* methods in Service Layer. Now my questions - A. Do I have to say get* as readonly? All my get* methods are pure read DB operations. I do not wish to run them in any transaction context. How serious is the above error? B. When I remove the get* confiiguration, I do not see the errors, morever all my simple get* operations are performed without transactions. Is this the way to go? C. Why would anyone want to have transactional methods where readonly = true? Is there any practical significance of this configuration? Thank you! As always your resposes are much appreciated!
