  • JPQL (JPA) search substring

    - by JavaBeginner
    Hi, Im facing simple problem with searching entities by some (sub)string, which they might contain. E.g. I have users user1, usr2, useeeer3, user4 and I will enter to search window "use" and I expect to return user1, useeer3, user4. Im sure you know what I mean now. Is there any construction in JPA (JQPL)? It would be nice to search using WHERE somehow in named queries. Something like "SELECT u FROM User u WHERE u.nickname contains :substring"

  • How to I create an HQL query to return objects in a many to many relationship?

    - by Dave
    Hi there. I have an application that includes 2 classes Club and Article. These are mapped in Hibernate as a many to many relationship. As a result, hibernate has created a table called CLUB_ARTICLE which it uses to manage the many to many relation ship. The CLUB and ARTILCE tables have no direct reference to each other and the mapping is only represented in the CLUB_ARTICLE table. I need to create an HQL query that returns a list of articles for a particlular club. So I need to supply the club id and get back a list of Article objects that belong to it. For some reason, I just can't work out how to do this. Any help would be very much appriciated! Thanks.

  • Click event to a Gwt-connector

    - by sprasad12
    Hi, I am trying to add click event to one of the widgets that use gwt-connector. Here is the code: public class Diagrams extends Diagram implements HasClickHandlers{ public Diagrams(AbsolutePanel boundaryPanel) { super(boundaryPanel); } @Override public HandlerRegistration addClickHandler(ClickHandler handler) { return addDomHandler(handler, ClickEvent.getType()); } @Override public void fireEvent(GwtEvent<?> event) { } } Here Diagram is a gwt-connector class. Here is the link to the Diagram class and also link to GWT-Connector. Question: Am i doing anything wrong in the code while adding the clickhandler? I am getting error saying that addDomHandler is undefined for the type Diagrams. are there limitations for adding click handlers? Any input will be of great help. Thank you.

  • Convert 4 bytes to int

    - by Oscar Reyes
    I'm reading a binary file like this: InputStream in = new FileInputStream( file ); byte[] buffer = new byte[1024]; while( ( in.read(buffer ) > -1 ) { int a = // ??? } What I want to do it to read up to 4 bytes and create a int value from those but, I don't know how to do it. I kind of feel like I have to grab 4 bytes at a time, and perform one "byte" operation ( like << & FF and stuff like that ) to create the new int What's the idiom for this? EDIT Ooops this turn out to be a bit more complex ( to explain ) What I'm trying to do is, read a file ( may be ascii, binary, it doesn't matter ) and extract the integers it may have. For instance suppose the binary content ( in base 2 ) : 00000000 00000000 00000000 00000001 00000000 00000000 00000000 00000010 The integer representation should be 1 , 2 right? :- / 1 for the first 32 bits, and 2 for the remaining 32 bits. 11111111 11111111 11111111 11111111 Would be -1 and 01111111 11111111 11111111 11111111 Would be Integer.MAX_VALUE ( 2147483647 )

  • Where to put a glossary of important terms and patterns in documentation?

    - by Tetha
    Greetings. I want to document certain patterns in the code in order to build up a consistent terminology (in order to easen communication about the software). I am, however, unsure, where to define the terms given. In order to get on the same level, an example: I have a code generator. This code generator receives a certain InputStructure from the Parser (yes, the name InputStructure might be less than ideal). This InputStructure is then transformed into various subsequent datastructures (like an abstract description of the validation process). Each of these datastructures can be either transformed into another value of the same datastructure or it can be transformed into the next datastructure. This should sound like Pipes and Filters to some degree. Given this, I call an operation which takes a datastructures and constructs a value of the same datastructure a transformation, while I call an operation which takes a datastructure and produces a different follow-up datastructure a derivation. The final step of deriving a string containing code is called emitting. (So, overall, the codegenerator takes the input-structure and transforms, transforms, derives, transforms, derives and finally emits). I think emphasizing these terms will be benefitial in communications, because then it is easy to talk about things. If you hear "transformation", you know "Ok, I only need to think about these two datastructures", if you hear "emitting", you know "Ok, I only need to know this datastructure and the target language.". However, where do I document these patterns? The current code base uses visitors and offers classes called like ValidatorTransformationBase<ResultType> (or InputStructureTransformationBase<ResultType>, and so one and so on). I do not really want to add the definition of such terms to the interfaces, because in that case, I'd have to repeat myself on each and every interface, which clearly violates DRY. I am considering to emphasize the distinction between Transformations and Derivations by adding further interfaces (I would have to think about a better name for the TransformationBase-classes, but then I could do thinks like ValidatorTransformation extends ValidatorTransformationBase<Validator>, or ValidatorDerivationFromInputStructure extends InputStructureTransformation<Validator>). I also think I should add a custom page to the doxygen documentation already existing, as in "Glossary" or "Architecture Principles", which contains such principles. The only disadvantage of this would be that a contributor will need to find this page in order to actually learn about this. Am I missing possibilities or am I judging something wrong here in your opinion? -- Regards, Tetha

  • Servlet, JSP, JavaBeans and HTML form

    - by dedalo
    Hi, I'm working on a servlet that makes a connection to a database gets the information of one of the tables ans sends this information to a jsp file. This file will print on the brower the information table, adding radio buttons that allows us to choose one of the rows. The servlet looks like this: List<InfoBean> items = new ArrayList<InfoBean>(); if (!conexion.isClosed()){ Statement st = (Statement) conexion.createStatement(); ResultSet rs = st.executeQuery("select * from lista_audio" ); while (rs.next()) {items.add(getRow(rs));} conexion.close();} req.getSession().setAttribute("items", items); In the JSP file I can print a table with the information, adding radio buttons that the user will use to choose 1 row and send the selected info to a servlet using a form I can add: < form action="administ" method=get enctype=multipart/form-data> < table> < table border=\"1\">< tr>< th>Title< /th>< th>Author< /th>< th>Album< /th>< /tr> < c:forEach items="${items}" var="item"> < tr>< td><input type="radio" name="SongInfo" value=${item.title}> < td>${item.title}< /td> < td>${item.author}< /td> < td>${item.album}< /td>< /tr> < /c:forEach> < /table> In the field 'value' I should be able to send to the servlet the information stored in ${item.title}. When I set value = ${item.title} and title is, for example "The bodyguard", in the servlet the information I can retrieve is just "The". It looks like it sends the characters located before the first white space of the string. How could I get the whole string? Thanks

  • How do I send an email with embedded images AND regular attachments in JavaMail?

    - by Chris
    Hi, I'd like to know how to build an SMTP multipart message in the correct order so that it will render correctly on the iPhone mail client (rendering correctly in GMail). I'm using Javamail to build up an email containing the following parts: A body part with content type "text/html; UTF-8" An embedded image attachment. A file attachment I am sending the mail via GMail SMTP (via SSL) and the mail is sent and rendered correctly using a GMail account, however, the mail does not render correctly on the iPhone mail client. On the iPhone mail client, the image is rendered before the "Before Image" text when it should be rendered afterwards. After the "Before Image" text there is an icon with a question mark (I assume it means it couldn't find the referenced CID). I'm not sure if this is a limitation of the iPhone mail client or a bug in my mail sending code (I strongly assume the latter). I think that perhaps the headers on my parts might by incorrect or perhaps I am providing the multiparts in the wrong order. I include the text of the received mail as output by gmail (which renders the file correc Message-ID: <[email protected]> Subject: =?UTF-8?Q?Test_from_=E3=82=AF=E3=83=AA=E3=82=B9?= MIME-Version: 1.0 Content-Type: multipart/mixed; boundary="----=_Part_0_20870565.1274154021755" ------=_Part_0_20870565.1274154021755 Content-Type: application/octet-stream Content-Transfer-Encoding: base64 Content-ID: <20100518124021763_368238_0> iVBORw0K ----- TRIMMED FOR CONCISENESS 6p1VVy4alAAAAABJRU5ErkJggg== ------=_Part_0_20870565.1274154021755 Content-Type: text/html; charset=UTF-8 Content-Transfer-Encoding: 7bit <html><head><title>Employees Favourite Foods</title> <style> body { font: normal 8pt arial; } th { font: bold 8pt arial; white-space: nowrap; } td { font: normal 8pt arial; white-space: nowrap; } </style></head><body> Before Image<br><img src="cid:20100518124021763_368238_0"> After Image<br><table border="0"> <tr> <th colspan="4">Employees Favourite Foods</th> </tr> <tr> <th align="left">Name</th><th align="left">Age</th><th align="left">Tel.No</th><th align="left">Fav.Food</th> </tr> <tr style="background-color:#e0e0e0"> <td>Chris</td><td>34</td><td>555-123-4567</td><td>Pancakes</td> </tr> </table></body></html> ------=_Part_0_20870565.1274154021755 Content-Type: text/plain; charset=us-ascii; name=textfile.txt Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=textfile.txt This is a textfile with numbers counting from one to ten beneath this line: one two three four five six seven eight nine ten(no trailing carriage return) ------=_Part_0_20870565.1274154021755-- Even if you can't assist me with this, I would appreciate it if any members of the forum could forward me a (non-personal) mail that includes inline images (not external hyperlinked images though).

  • Hibernate, EHCache, Read-Write cache, adding item to a list

    - by Walter White
    Hi all, I have an entity that has a collection in it. The collection is a OneToMany unidirectional relationship storing who viewed a particular file. The problem I am having is that after I load the entity and try to update the collection, I don't get any errors, but the collection is never updated: Entity: @OneToMany(cascade = CascadeType.PERSIST) @JoinTable protected List<User> users; File Servlet @In private EntityQuery<File> File_findById; ... File file = File_findById(fileId); file.getUsers().add(user); session.update(file); Even though I call session.update(file) and I see stuff in hibernate logs, I don't see anything in the database indicating that it was saved.

  • Jalopy comments indentation

    - by Neil Wightman
    Hi All. We use jalopy to format our code to the sun standard (well 99%). I have 1 issue with it. It keeps moving comments to the right of the line. E.g // Panel "JPanel.border", new LazyValue(packageName + "PanelBorder"), //frozen // Button "Button.background", new ColorUIResource(251, 251, 251), //frozen "Button.foreground", new ColorUIResource(0, 0, 0), //frozen But jalopy always moves the // Button to the far right. // Panel "JPanel.border", new LazyValue(packageName + "PanelBorder"), //frozen // Button "Button.background", new ColorUIResource(251, 251, 251), //frozen "Button.foreground", new ColorUIResource(0, 0, 0), //frozen Is there any way to stop this? Thanks Neil

  • Can't open Websphere Portal 7.0 Login Page after its integration with a custom user registry?

    - by jack_sparrow
    I am currently working on a project related to Websphere Portal 7.0 on Windows Server 2008 R2,64 bit. I am trying to integrate websphere portal with my custom user registry.I have completed all the steps required to implement custom user registry in portal as given in IBM documentation.I am adding my custom repository to the default federated repositories of Portal 7.0.I have made the required changes under VMM Federated CUR Properties section in wkplc.properties.I am using configengine.bat file to configure Portal with user registry. But even completing all the steps,when I am trying to open the Portal Login Page through http://ip-address:port_of_portal/wps/portal ,it is throwing an exception on the console: "Error 500: com.ibm.wps.resolver.data.exceptions.URIProcessingIOException: EJCBD0021E: The URI dav:fs-type1/themes/PageBuilder2/theme.html and parameters [['themeURI'=, 'mime-type'= could not be processed: [EJCBD0021E: The URI dav:fs-type1/themes/PageBuilder2/theme.html and parameters [['themeURI'=, 'mime-type'= could not be processed: EJPSG0002E: Requested Member does not exist.uid=portal,o=defaultWIMFileBasedRealm/null] " and in logs Systemout.log "EJPSB0005E: Exception occurred during creation of the principal with Name uid=portal,o=defaultWIMFileBasedRealm and Principal Type USER caused by com.ibm.portal.puma.MemberNotFoundException: EJPSG0002E: Requested Member does not exist.uid=portal,o=defaultWIMFileBasedRealm/null".

  • JDK-7 SwingWorker deadlocks?

    - by kd304
    I have a small image processing application which does multiple things at once using SwingWorker. However, if I run the following code (oversimplified excerpt), it just hangs on JDK 7 b70 (windows) but works in 6u16. It starts a new worker within another worker and waits for its result (the real app runs multiple sub-workers and waits for all this way). Did I use some wrong patterns here (as mostly there is 3-5 workers in the swingworker-pool, which has limit of 10 I think)? import javax.swing.SwingUtilities; import javax.swing.SwingWorker; public class Swing { static SwingWorker<String, Void> getWorker2() { return new SwingWorker<String, Void>() { @Override protected String doInBackground() throws Exception { return "Hello World"; } }; } static void runWorker() { SwingWorker<String, Void> worker = new SwingWorker<String, Void>() { @Override protected String doInBackground() throws Exception { SwingWorker<String, Void> sw2 = getWorker2(); sw2.execute(); return sw2.get(); } }; worker.execute(); try { System.out.println(worker.get()); } catch (Exception e) { e.printStackTrace(); } } public static void main(String[] args) { SwingUtilities.invokeLater(new Runnable() { @Override public void run() { runWorker(); } }); } }

  • using Swing components in javafx if they're not in the NetBeans javafx palette

    - by Jason S
    I'm just getting started with javafx in NetBeans, and I have it doing simple stuff (windows with buttons + the like) but would like to try something slightly more realistic. The "Swing/AWT Components" palette has a whole bunch of stuff that the "JavaFX Script Code Clips" palette does not (it has Button, CheckBox, ComboBox, ComboBoxItem, Label, RadioButton, Slider, TextField, and ToggleButton). How do I add stuff to this palette? I would like to try using some of the components in org-netbeans-swing-outline.jar edit: Aha. I was missing the point somewhat: there are only some javafx-wrapped Swing components available in javafx.ext.Swing.*, so if you want one of the other Swing components you have to wrap them yourself.

  • TeamCity and pending Git merge branch commit keeps build with failed tests

    - by Vladimir
    We use TeamCity for continuous integration and Git for source control. Generally it works pretty well - convenient, modern and good us quick feedback when tests fails. There is a strange behavior related to Git merge specifics. Here are steps of the case: First developer pulls from master repo. Second developer pulls from master repo. First developer makes commit A locally. Second developer makes commit B locally; Second developer pushes commit B. First developer want to push commit A but unable because he have to pull commit B first. First developer pull's from remote reposity. First developer pushes commit A and generated merge branch commit. The history of commits in master repo is following: B second developer A first developer merge branch first developer. Now let's assume that Second Developer fixed some failing tests in his commit B. What TeamCity will do is following: Commit B arrives - TeamCity makes build #1 with all tests passed Commit A arrives - TeamCity makes build #2 (without commit B) test bar becomes Red! TeamCity thought that Pending "Merge Branch" commit doesn't contain any changes (any new files) - but it actually does contain the merge of commit B, so the TeamCity don't want to make new build here and make tests green. Here are two problems: 1. In our case we have failed tests returning back in second commit (commit A) 2. TeamCity don't want to make a new build and make tests back green. Does anybody know how to fix both of this problems. I consider some reasonable general approach.

  • Spring - SessionAttribute problem

    - by Max
    Hello, I want to implement something like this: @Controller @SessionAttributes("promotion") class PromotionController { @RequestMapping("showPromo") void showPromotionInfo( @RequestParam("promId") String promotionId, @ModelAttribute Promotion promotion, Errors errors ) { promotion = Promotions.get(promotionId); if (promotion == null || promotion.validates() == false) { errors.reject("promotion.invalid"); } return "prom"; } } The code is invalid, wont work and has some bad errors, but I don't know how to write it better. When user comes to an URL "showPromo?promId=15", controller should validate if the promotion is valid (outdated/non-existent/etc.). If it is valid - it should show it's information and save the promotion to model and session. If it's not - it should show some error about promotion being invalid. Problem is, I need to save the promotion in the session (for several requests) and don't want to use direct session management. Is it currently possible with Spring? Or am I doing something wrong? Could you please provide the optimal solution to my problem using Spring 3? Thanks in advance.

  • Dependency on Spring's annotations

    I have annotated my classes with @Repository, @Resource, @Component, @Service annotations but these classes must run in 2 environments. The first environment is Spring 2.x based while the other has no spring at all. I'm sure the code will fail without the spring jars & I want to know ideas from you on how I can retain the annotations but still work in both environments

  • SIP servlets, chatserver

    - by Senne
    I'm trying to get a SIP servlet chat server working, together with the textclient found here. When I use 2 clients to send messages to eachother (peer to peer), everything goes well. But when I use one or more clients together with my server, I have to wait exactly 32 seconds before the server picks up any new messages in the doMessage() method. I'm using Netbeans together with Sailfin as my SIP server. Is there some kind of limitation or configurable delay or timeout between requests or responses in Sailfin I'm looking over? I can post the server code, if needed. Thanks
