  • What's the correct way to read an inputStream into a node property in JCR 2?

    - by Stuart
    In JCR 1 you could do: final InputStream in = zip.getInputStream(zip.getEntry(zipEntryName)); node.setProperty(JcrConstants.JCR_CONTENT, in); But that's deprecated in JCR 2 as detailed at http://www.day.com/maven/jsr170/javadocs/jcr-2.0/javax/jcr/Node.html#setProperty%28java.lang.String,%20java.io.InputStream%29 That says I should be using node.setProperty(String, Binary) but I don't see any way to turn my inputStream into a Binary. Can anyone point me to docs or example code for this?

  • Ensure a new session every time the user connects to a Servlet

    - by Daziplqa
    Hi, I've a JSP/Servlet Web App that consist of more than one servlet (and some JSPs) I need to create an new HttpSession whenever the users access servlet A, knowing that, servlet A is the home page (i.e. he access it as the first servlet/page in the application) so far so good, I can write the following code at the start of the servlet A: HttpSession session = request.getSession(false); if (session == null) { logger.debug("starting new session..."); session = request.getSession(); // other staff here } But the problem is, if the user didn't close his browser (even if he closes the tab - in firefox for instance - the session will still be open), so when he try to open my site again, the last session will be re-used (in the rage of session timeout ofcourse), and this I don't need. I need whenever he access Servlet A, he got created a brand new HttpSession. but unfortunately, he may access this servlet twice per session based on some scenario!! Please help.

  • What can I access in Androids Native libraries? And How?

    - by Donal Rafferty
    I am completely new to the NDK. I have done a couple of the tutorials including the hello from jni one and another one that calculates the sum of two numbers. They involved using cygwin and the ndk to create the library so file and I have a bit of a grasp on how to insert my own libraries into the libraries layer of Android. I have now been asked to access the native libraries on Android and see what I can use them for. My question is can I do this? The STABLE-APIS.txt document is a bit vague and mentions the following as Stable C++ API's in Android 1.5 cstddef new utility stl_pair.h Does that mean I can access them? If so then how do I go about it? I dont think that following the tutorials I have already done would be any help? Any pointers on how to do this or links to tutorials etc.. would be greatly appreciated

  • 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"

  • Dispatcher for Filter Mapping

    - by George
    I have an app written for Servlet Spec 2.4 with an old webserver designed for Servlet Spec 2.3. The web.xml file has the following syntax: <filter-mapping> <filter-name>sitemesh</filter-name> <url-pattern>*.action</url-pattern> <dispatcher>REQUEST</dispatcher> <dispatcher>FORWARD</dispatcher> </filter-mapping> How can I re-write this mapping to be servlet 2.3 compliant?

  • using JMock to write unit test for a simple spring JDBC DAO

    - by Quincy
    I'm writing an unit test for spring jdbc dao. The method to test is: public long getALong() { return simpleJdbcTemplate.queryForObject("sql query here", new RowMapper<Long>() { public Long mapRow(ResultSet resultSet, int i) throws SQLException { return resultSet.getLong("a_long"); } }); } Here is what I have in the test: public void testGetALong() throws Exception { final Long result = 1000L; context.checking(new Expectations() {{ oneOf(simpleJdbcTemplate).queryForObject("sql_query", new RowMapper<Long>() { public Long mapRow(ResultSet resultSet, int i) throws SQLException { return resultSet.getLong("a_long"); } }); will(returnValue(result)); }}); Long seq = dao.getALong(); context.assertIsSatisfied(); assertEquals(seq, result); } Naturally, the test doesn't work (otherwise, I wouldn't be asking this question here). The problem is the rowmapper in the test is different from the rowmapper in the DAO. So the expectation is not met. I tried to put with around the sql query and with(any(RowMapper.class)) for the rowmapper. It wouldn't work either, complains about "not all parameters were given explicit matchers: either all parameters must be specified by matchers or all must be specified by values, you cannot mix matchers and values"

  • in which namespace / package to put exceptions

    - by Fabiano
    Hi What is the common or best practice to structure the location of your exception classes? Let's say you have the packages/namespaces myproject.person (models and DAOs for persons) and myproject.order (models and DAOs for orders) and the exceptions PersonException and OrderException. Should I put the exceptions in their corresponding packages or in a separate package for exceptions (e.g. myproject.exceptions)? The first approach seems more reasonable (because it's sorted by functionality). But there the question arises where you should put exceptions that are related to both? e.g. a ConstraintViolationException Thanks

  • Repeated Scene Trees (Java3d / OpenGL)

    - by Jim
    Hello, I want to make a 3d scene that loops around on its self. That is to say, if you keep going in any direction, you will loop back to the other side. My current implementation is so bad, it's embarrassing to admit to it. I redraw the each change twenty-seven times, to make a 3x3x3 scene cube. When the user reaches the end of the middle cube, I jump them over to the other side. Maintaining consistency (let alone performance) is a nightmare. Total Disaster. This doesn't seem like it would be an unusual request, so I'm wondering if anyone knows of a more legit solution. 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 does Tomcat append / to directory paths?

    - by Anonymouse
    Suppose my Tomcat webapps directory looks like this: webapps/ webapps/fooapp/ webapps/fooapp/WEB-INF/ webapps/fooapp/WEB-INF/web.xml webapps/fooapp/bardir/ When I make a GET request for /fooapp/bardir, Tomcat sees that webapps/fooapp/bardir is a directory and sends back a 302 to /fooapp/bardir/ (with a slash at the end). Here is my question: Where in the Tomcat source code does this take place? (I'm looking at 6.0.x but a correct answer for any version would be a great starting point.) The only reference material I can find on this subject is in the Catalina Functional Specifications which states, regarding the Default Servlet: On each HTTP GET request processed by this servlet, the following processing shall be performed: [...] If the requested resource is a directory: If the request path does not end with "/", redirect to a corresponding path with "/" appended so that relative references in welcome files are resolved correctly. However, this functionality does not appear to be in org.apache.catalina.servlets.DefaultServlet; or at least, it's not there exclusively: if I replace the default servlet in web.xml with a servlet whose servlet-class does not exist, directory paths still come back 302 to add the slash, while every other request comes back with an error as expected.

  • BlazeDS StreamingAMF: How to detect when flex client closes the connection?

    - by Adrian Pirvulescu
    Hello, I have a Flex application that connects to a BlazeDS server using the StreamingAMF channel. On the server-side the logic is handled by a custom adapter that extends ActionScriptAdapter and implements FlexSessionListener and FlexClientListener interfaces. I am asking how can I detect which "flex-client" has closed a connection when for example the user is closing the browser? (so I can clean some infos inside the database) I tried using the following: 1. To manually manage the command messages: @Override public Object manage(final CommandMessage commandMessage) { switch (commandMessage.getOperation()) { case CommandMessage.SUBSCRIBE_OPERATION: System.out.println("SUBSCRIBE_OPERATION = " + commandMessage.getHeaders()); break; case CommandMessage.UNSUBSCRIBE_OPERATION: System.out.println("UNSUBSCRIBE_OPERATION = " + commandMessage.getHeaders()); break; } return super.manage(commandMessage); } But the clientID's are always different from the ones that came. 2. Listening for sessionDestroyed and clientDestroyed events @Override public void clientCreated(final FlexClient client) { client.addClientDestroyedListener(this); System.out.println("clientCreated = " + client.getId()); } @Override public void clientDestroyed(final FlexClient client) { System.out.println("clientDestroyed = " + client.getId()); } @Override public void sessionCreated(final FlexSession session) { System.out.println("sessionCreated = " + session.getId()); session.addSessionDestroyedListener(this); } @Override public void sessionDestroyed(final FlexSession session) { System.out.println("sessionDestroyed = " + session.getId()); } But those sessionDestroyed and clientDestroyed methods are never called. :(

  • 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).

  • 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

  • Spring: PropertyPlaceHolderConfigurer to set values for non-string/integer properties

    - by babyangel86
    Hi, All the examples I have seen where the PropertyPlaceHolderConfigurer is used seem to be setting simple values like Strings and ints. How do you use the PPC to set the values of classes. E.g. If i had a class signature Source(String name, DistributionSample batch, DistributionSample delay) How would I go about setting the batch and delay properties. There is also a small catch. DistributionSample is an abstract class. On the bright side, The class that is using the propertyPlaceHolder knows the beanName of the "Solid" class that needs to be instantiated. Any help would be much appreciated.

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

    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.
