  • How to generate hibernate POJO classes programmatically?

    - by Vatsala
    Hi I am aware of the Hibernate Eclipse plugin that helps us (through a series of screens and button clicks) to generate the POJO and DAO classes for the underlying tables. But I would like to mimic this in a runtime environment, i.e. I would like to be able to do the exact same steps programmatically , where I should be able to supply the .cfg.xml file, the reveng.xml file, the database URL, the destination folder, via a command line/ parameters within main(String[] args).. Apparently there is no such tool available which works in a pure Hibernate scenario. There is one which is tuned to generate code for the spring framework - but thats not of direct use to me right now. I tried downloading hibernate-tools.jar's source code for the eclipse plugin, but right now the src code download link at hibernate.org(new design) has been disabled for some reason. Has anyone handled such a thing before? Or can you give me some clues to do this? I have tried a certain JDBCReader class's object, the rationale being read all tables using JDBCReader's methods and then figure out how to use hbm2POJO generator class....

  • unable to place breakpoints in eclipse

    - by anjanb
    I am using eclipse europa (3.5) on windows vista home premium 64-bit using JDK 1.6.0_18 (32 BIT). Normally, I am able to put breakpoints just fine; However, for a particular class which is NOT part of the project (this class is inside a .JAR file (.JAR file is part of the project) ), although I have attached a source directory to this .JAR file, I am unable to place a breakpoint in this class. If I double-click on the breakpoint pane(left border), I notice that a class breakpoint is placed. I was wondering if there was NO debug info; However, found that this particular class was compiled using ant/javac task using debug="true" and debuglevel="lines,vars,source". I even ran jad on this class to confirm that it indeed contained the debug info. So, why is eclipse preventing me from placing a breakpoint ? EDIT : Just so everyone understands the context, this is a webapp running under tomcat 6.0. I am remote debugging the application from eclipse after having started tomcat outside. The application is working just fine. I am trying to understand the behavior of the above class which I'm unable to do since eclipse is not letting me set a BP. P.S : I saw a few threads here talking about BPs not being hit but in my case, I am unable to place the BP! P.P.S : I tried JDK 1.6.0_16 before trying out 1.6.0_18. Thanks for any pointers.

  • Distributed sequence number generation?

    - by Jon
    I've generally implemented sequence number generation using database sequences in the past. e.g. Using Postgres SERIAL type http://neilconway.org/docs/sequences/ I'm curious though as how to generate sequence numbers for large distributed systems where there is no database. Does anybody have any experience or suggestions of a best practice for achieving sequence number generation in a thread safe manner for multiple clients?

  • Is selling a "website screen scraper" is illegal?

    - by Yatendra Goel
    I have coded a "website screen scraper" and want to sell it commercially. I know that webpages scraped by the screen scraper are restricted to be scraped by the webmaser of that website. The robots.txt file of the website says that its webpages must not be scraped. So my question is whether selling that screen scraper is a crime or using that screen scraper is a crime in legal terms. I know that this question is related to law but I thought the software experts on SO must also have answer to this question.

  • Saving twice don't update my object in JDO

    - by Javi
    Hello I have an object persisted in the GAE datastore using JDO. The object looks like this: public class MyObject implements Serializable, StoreCallback { @PrimaryKey @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY) @Extension(vendorName="datanucleus", key="gae.encoded-pk", value="true") private String id; @Persistent private String firstId; ... } As usually when the object is stored for the first time a new id value is generated for the identifier. I need that if I don't provide a value for firstId it sets the same value as the id. I don't want to solve it with a special getter which checks for null value in firstId and then return the id value because I want to make queries relating on firstId. I can do it in this way by saving the object twice (Probably there's a better way to do this, but I'll do it in this way until I find a better one). But it is not working. when I debug it I can see that result.firstId is set with the id value and it seems to be persisted, but when I go into the datastore I see that firstId is null (as it was saved the first time). This save method is in my DAO and it is called in another save method in the service annotated with @Transactional. Does anyone have any idea why the second object in not persisted properly? @Override public MyObject save(MyObject obj) { PersistenceManager pm = JDOHelper.getPersistenceManagerFactory("transactions-optional"); MyObject result = pm.makePersistent(obj); if(result.getFirstId() == null){ result.setFirstId(result.getId()); result = pm.makePersistent(result); } return result; } Thanks.

  • I didn't say anything treasonous, quit putting words in my mouth

    - by You guys Lie
    Where at all did I say ANYTHING about organizing some kind of anti-government activity? Nowhere. I do not give a flying fuck about America in case you hadn't realized, I'm talking about what I'm going to do when Jesus Christ returns. Besides, why would I make it easy for them to throw me in a black site prison? Use common sense, sheeple. In the end I guess it doesn't matter anyways, since I do not recognize the government as my ultimate authority. Police/Army/Whatever-- funny outfits and a shiny badge don't make you better than me. Allah will do away with your kind. However, as long as they're with me (as they semi-currently are), we have no problems. I fear the government will have other plans to control the population when things start to further decline, and that is when they will run into problems with me and mine, and probably a large percentage of the public. You'd have to be a fucking fool to think we'd fall into anarchy immediately, given the vast resources and blind loyalty of this country. Saying there are practical limits to free speech for anything I have said in this thread is not only ignorant, it is unpatriotic. I should be being celebrated as the modern day Paul Revere for warning you people about our impending doom. You would do well to study the foundations of this country. Nothing I have said is treasonous at all. Besides, the DoD knows I'm harmless until shit pops off, they have bigger fish to fry right now, go forward. Keep in mind, I don't personally have to do anything to overthrow the government. I just said, I would not advocate for any paramilitary organizations at this time, only if/after we dissolve into (more) tyranny. I am not a terrorist, like some soldiers in Iraq. The machine is doing a great job of ruining itself, while I get to comfortably laugh at it on the nightly news knowing that I'm ready for it to shut down.

  • Emulating HTTP POST via httpclient 3.x for multi options

    - by Frankie Ribery
    I want to emulate a HTTP POST using application/x-www-form-urlencoded encoding to send a option group that allows multiple selections. <select name="groups" multiple="multiple" size="4"> <option value="2">Administration</option> <option value="1">General</option> </select> Does adding 2 NameValuePairs (NVP) with the same name work ? My serverside log shows that only the first NVP was received. e.g PostMethod method = ...; NameValuePair[] nvpairs = { new NameValuePair( "groups", "2" ); new NameValuePair( "groups", "1" ); }; method.addParameter( nvpairs ); Only the groups=1 parameter was received. Thanks

  • How do I create an EAR file with an ant build including certain files?

    - by user149100
    I'm using eclipse to build an ear file using ant. I'm using oc4j, and I want to make sure that orion-application.xml is included in the build. What I'm currently using but does not work is: <target name="ear" depends="" <echoBuilding the ear file</echo <copy todir="${build.dir}/META-INF" <fileset dir="${conf.dir}" includes="orion-application.xml"/ </copy <ear destfile="${dist.dir}/${ant.project.name}.ear" appxml="${conf.dir}/application.xml" <fileset dir="${dist.dir}" includes="*.jar,*.war"/ </ear </target What is the right way to add this to the ear?

  • Cross field validation in jsf h:datatable using p:calendar

    - by Matt Broekhuis
    I noticed this question was asked, but it has not been answered correctly. I have a datatable that has two columns start date and end date. Both contain primefaces p:calendar controls in them. I need to ensure that for each row that the date in column1 is not after the date in column2. I would like to tie this into the JSF validation framework, but I'm having trouble. i've tried marking the datatable rowStatePreserved="true" , this allows me to get the values, but something is still wrong as when it fails, all the values in the first row overwrite all the other values. What am I doing wrong, or should I be using a completely different strategy? xhtml code <h:form> <f:event type="postValidate" listener="#{bean.doCrossFieldValidation}"/> <p:dataTable id="eventDaysTable" value="#{course.courseSchedules}" var="_eventDay" styleClass="compactDataTable" > <p:column id="eventDayStartColumn"> <f:facet name="header"> Start </f:facet> <p:calendar id="startDate" required="true" value="#{_eventDay.startTime}" pattern="MM/dd/yyyy hh:mm a"/> </p:column> <p:column id="eventDayEndColumn"> <f:facet name="header"> End </f:facet> <p:calendar id="endDate" required="true" value="#{_eventDay.endTime}" pattern="MM/dd/yyyy hh:mm a"/> </p:column> </p:dataTable> </h:form> validationCode public void doCrossFieldValidation(ComponentSystemEvent cse) { UIData eventsDaysStable = (UIData) cse.getComponent().findComponent("eventDaysTable"); if (null != eventsDaysStable && eventsDaysStable.isRendered()) { Iterator<UIComponent> startDateCalendarIterator = eventsDaysStable.findComponent("eventDayStartColumn").getChildren().iterator(); Iterator<UIComponent> endDateCalendarIterator = eventsDaysStable.findComponent("eventDayEndColumn").getChildren().iterator(); while (startDateCalendarIterator.hasNext() && endDateCalendarIterator.hasNext()) { org.primefaces.component.calendar.Calendar startDateComponent = (org.primefaces.component.calendar.Calendar) startDateCalendarIterator.next(); org.primefaces.component.calendar.Calendar endDateComponent = (org.primefaces.component.calendar.Calendar) endDateCalendarIterator.next(); Date startDate = (Date) startDateComponent.getValue(); Date endDate = (Date) endDateComponent.getValue(); if (null != startDate && null != endDate && startDate.after(endDate)) { eventScheduleChronologyOk = false; startDateComponent.setValid(false); endDateComponent.setValid(false); } } if (!eventScheduleChronologyOk) { showErrorMessage(ProductManagementMessage.PRODUCT_SCHEDULE_OUT_OF_ORDER); } } }

  • JFreeChart Legend Display

    - by Richard B
    In my JFreeChart timeseries plots I find the legends lines to thin to see the colour accurately. Another post [ jfreechart - change sample of colors in legend ] suggested overriding a renderer method as follows: renderer = new XYLineAndShapeRenderer() { private static final long serialVersionUID = 1L; public Shape lookupLegendShape(int series) { return new Rectangle(15, 15); } }; this approach works fine until you do what I did renderer.setSeriesShapesVisible(i, false); Once I did that the legend reverts back to a line. Is there any way round this?

  • Ghost activity in android

    - by Ari
    My application works as follow: On start I have some AppStartActivity which does something, finishes itself and starts MainActivity if user is logged in or LoginActivity otherwise. LoginActivity finishes itself and starts MainActivity when user log in successfully. On MainActivity I have SomeActivity from which user can logout. Activity stack for this situation is MainActivity > SomeActivity. It is correct, back button works well. When user click LogOut button there is a problem. I need to show LoginActivity but I don't want to have MainActivity and SomeActivity on activity stack anymore. I could resolve this problem if I wouldn't finish AppStartActivity. I could go back then with flag FLAG_ACTIVITY_CLEAR_TOP and it would work well. But here is a problem with back button. I don't want user to come back to this activity with back button. I want it to exit app instead. UPDATED: Flags FLAG_ACTIVITY_NEW_TASK and FLAG_ACTIVITY_CLEAR_TASK would be best, but I need it working in API level 9.

  • Invert bitmap colors

    - by Alex Orlov
    I have the following problem. I have a charting program, and it's design is black, but the charts (that I get from the server as images) are light (it actually uses only 5 colors: red, green, white, black and gray). To fit with the design inversion does a good job, the only problem is that red and green are inverted also (green - pink, red - green). Is there a way to invert everything except those 2 colors, or a way to repaint those colors after inversion? And how costly are those operations (since I get the chart updates pretty often)? Thanks in advance :) UPDATE I tried replacing colors with setPixel method in a loop for(int x = 0 ;x < chart.getWidth();x++) { for(int y = 0;y < chart.getHeight();y++) { final int replacement = getColorReplacement(chart.getPixel(x, y)); if(replacement != 0) { chart.setPixel(x, y, replacement); } } } Unfortunetely, the method takes too long (~650ms), is there a faster way to do it, and will setPixels() method work faster?

  • null != null - any ideas on how to re-arrange the code or prevent this?

    - by Alex
    Currently debugging, and found an if-statement which for no (I thought...) reason gave me an NPE, obviously for a reason. Which seemed to be that the statement turned out to be if(false && (null != null || null != Color)). if(destination != null && (destination.getPiece() != null || destination.getPiece().getColour() != pieceColour)) - the if-statement Both destination can be null and piece can be. The getColour() method returns an attribute of type Color from piece, which must be null if the piece is null. The piece at destination has a different pieceColour attribute then the one in the if-statement. Specifically, how do I re-arrange (destination.getPiece() != null) ?

  • Can't read some attributes with SAX

    - by akappa
    Hi all, I'm trying to parse that document with SAX: <scxml version="1.0" initialstate="start" name="calc"> <datamodel> <data id="expr" expr="0" /> <data id="res" expr="0" /> </datamodel> <state id="start"> <transition event="OPER" target="opEntered" /> <transition event="DIGIT" target="operand" /> </state> <state id="operand"> <transition event="OPER" target="opEntered" /> <transition event="DIGIT" /> </state> </scxml> I read all the attributes well, except "initialstate" and "name"... I get the attributes with the startElement handler, but the size of the attribute list for scxml is zero. Why? How I can overcome that problem? Edit: public void startElement(String uri, String localName, String qName, Attributes attributes){ System.out.println(attributes.getValue("initialstate")); System.out.println(attributes.getValue("name")); } that, when parsing the first tag, doesn't work (prints "null" two times). In fact, attributes.getLength(); evaluates to zero. Thanks

  • Jad file download link for my website

    - by Jareim
    Hi sir/madam! I am putting up a small website via webs.com for me and my friends that could also be accessible via wap, i.e. mobile internet, and I want to add links to my site that downloads .jar files. I uploaded the files on my site, and links to the .jar files went fine, but I also need links for .jad files (for some mobile phones that require .jad files FIRST then .jar). I tried doing a regular link for the .jad files, but it simply displayed the content of the .jad file. It wasn't installed or downloaded. What should I do? Or am I at a wrong website? Thanks!

  • Setting up ehcache replication - what multicast settings do I need?

    - by Darren Greaves
    I am trying to set up ehcache replication as documented here: http://ehcache.sourceforge.net/EhcacheUserGuide.html#id.s22.2 This is on a Windows machine but will ultimately run on Solaris in production. The instructions say to set up a provider as follows: <cacheManagerPeerProviderFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory" properties="peerDiscovery=automatic, multicastGroupAddress=230.0.0.1, multicastGroupPort=4446, timeToLive=32"/> And a listener like this: <cacheManagerPeerListenerFactory class="net.sf.ehcache.distribution.RMICacheManagerPeerListenerFactory" properties="hostName=localhost, port=40001, socketTimeoutMillis=2000"/> My questions are: Are the multicast IP address and port arbitrary (I know the address has to live within a specific range but do they have to be specific numbers)? Do they need to be set up in some way by our system administrator (I am on an office network)? I want to test it locally so am running two separate tomcat instances with the above config. What do I need to change in each one? I know both the listeners can't listen on the same port - but what about the provider? Also, are the listener ports arbitrary too? I've tried setting it up as above but in my testing the caches don't appear to be replicated - the value added in one tomcat's cache is not present in the other cache. Is there anything I can do to debug this situation (other than packet sniffing)? Thanks in advance for any help, been tearing my hair out over this one!

  • JComponent undock effect

    - by Christo Du Preez
    I'm trying to accomplish an undock effect for a custom Swing JComponent. By default the component is used inside a form along with other components. I want to be able to maximize this component to use the whole screen and then be able to dock it again. So far I've tested public void showDialog() { JFrame mainFrame = App.getApplication().getMainFrame(); JDialog dialog = new JDialog(mainFrame); dialog.setModal(true); dialog.setSize(800, 600); //Set to 80x660 for now dialog.add(this); //This is my JComponent dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE); dialog.setVisible(true); } This gives me desired effect but when closing the dialog my component doesn't receive events no more. How can I prevent this? Or is there perhaps a better way to accomplish this?

  • Are JSF 2.x ViewScoped Beans Thread Safe?

    - by Mark
    I've been googling for a couple hours on this issue to no eval. WELD docs and the CDI spec are pretty clear regarding thread safety of the scopes provided. For example: Application Scope - not safe Session Scope - not safe Request Scope - safe, always bound to a single thread Conversation Scope - safe (due to the WELD proxy serializing access from multiple request threads) I can't find anything on the View Scope defined by JSF 2.x. It is in roughly the same bucket as the Conversation Scope in that it is very possible for multiple requests to hit the scope concurrently despite it being bound to a single view / user. What I don't know is if the JSF implementation serializes access to the bean from multiple requests. Anyone have knowledge of the spec or of the Morraja/MyFaces implementations that could clear this up?
