  • Use of Hibernate 3.0 with EJB 3.0 & JPA

    - by SOA Nerd
    Where I'm working the guys that are sitting across from me are working on a project. This is a JavaEE app which uses Struts, Spring, EJB 3.0, JPA, and Hibernate 3.0. They are using EJB 3.0 entity beans with annotations. I've been asking them why Hibernate 3.0 is in this mix and noone can seem to tell me. It feels like they've included Hibernate 3.0 because they were told to but are not using it for anything that they can't get from EJB 3.0 entity beans/JPA. They're using CMP and accessing all of the database functions via EJBs. Can Hibernate give you anything in this setup that can't be provided by EJB 3.0/JPA?

  • Drools Rules: How can I use a method on "when" section?

    - by manoelhc
    Hi, I need to execute a method on "when" section of a DSLR file and I´m not sure if it´s possible. Example: rule "WNPRules_10" when $reminder:Reminder(source == "HMI") $user:User(isInAgeRange("30-100")==true) Reminder(clickPercentual >= 10) User(haveAtLeastOptIns("1,2,3,4") == true) then $reminder.setPriority(1);update($reminder); end (note: isInAgeRange() and haveAtLeastOptIns() are methods of User) I tried with eval() and no errors appeared, but it didn´t execute. Like this: rule "WNPRules_10" when $reminder:Reminder(source == "HMI") $user:User(eval($user.isInAgeRange("30-100")==true)) Reminder(clickPercentual >= 10) User(eval($user.haveAtLeastOptIns("1,2,3,4") == true)) then $reminder.setPriority(1);update($reminder); end How can I resolve this problem?

  • Custom view in ListView disappears while scrolling in Android

    - by troorl
    Hi. I wrote a simple custom view for rows in ListView. It works fine, but when I try to scroll the list, I see only white rows without content. And when scrolling is over, rows continue to show again. This is how I draw a custom view: @Override protected void onDraw(Canvas canvas) { if(poster != null) { canvas.drawBitmap(poster, padding, padding, paint); } canvas.drawText(title, 55 + padding, 16 + padding, paint); } Maybe I missed something? P.S. This is short screencast (400kb) http://dl.dropbox.com/u/190203/test.mpeg

  • Hibernate ScrollableResults Do Not Return The Whole Set of Results

    - by mlaverd
    Some of the queries we run have 100'000+ results and it takes forever to load them and then send them to the client. So I'm using ScrollableResults to have a paged results feature. But we're topping at roughly 50k results (never exactly the same amount of results). I'm on an Oracle9i database, using the Oracle 10 drivers and Hibernate is configured to use the Oracle9 dialect. I tried with the latest JDBC driver (ojdbc6.jar) and the problem was reproduced. We also followed some advice and added an ordering clause, but the problem was reproduced. Here is a code snippet that illustrates what we do: Criteria crit = sess.createCriteria(ABC.class); crit.add(Restrictions.eq("property", value)); crit.setFetchSize(pageSize); crit.addOrder(Order.asc("property")); ScrollableResults sr = crit.scroll(); ... ... do{ for (Object entry : page) sess.evict(entry); //to avoid having our memory just explode out of proportion page.clear(); for (int i =0 ; i < pageSize && ! metLastRow; i++){ if (resultSet.next()) page.add(sr.get(0)); else metLastRow = true; } metLastRow = metLastRow?metLastRow:sr.isLast(); sendToClient(page); }while(!metLastRow); So, why is it that I get the result set to tell me its at the end when it should be having so much more results?

  • JSP Document/JSPX: what determines how space/linebreaks are removed in the output?

    - by NoozNooz42
    I've got a "JSP Document" ("JSP in XML") nicely formatted and when the webpage is generated and sent to the user, some linebreaks are removed. Now the really weird part: apparently the "main" .jsp always gets all its linebreak removed but for any subsequent .jsp included from the main .jsp, linebreaks seems to be randomly removed (some are there, others aren't). For example, if I'm looking at the webpage served from Firefox and ask to "view source", I get to see what is generated. So, what determines when/how linebreaks are kept/removed? This is just an example I made up... Can you force a .jsp to serve this: <body><div id="page"><div id="header"><div class="title">... or this: <body> <div id="page"> <div id="header"> <div class="title">... ? I take it that linebreaks are removed to save on bandwidth, but what if I want to keep them? And what if I want to keep the same XML indentation as in my .jsp file? Is this doable?

  • How to add a dynamic library to Android?

    - by Malcolm
    I want to add a non-native shared library to Android so every application on the device would be able to use it. I mean using packaged classes just like a core library as if they were present in the application itself. I studied Android source code to figure out a way to add a new path to the application ClassLoader and found out that it is created during startup and there's no way to change the paths later. I can use my own ClassLoader, but all I will get after loading a class will be a reference to a Class object. This way I will be bound to work through reflection mechanism, which is slower than the native execution system. Is there any way to organise a shared library on Android?

  • How to figure out which jars are needed?

    - by Ari
    How can I systematically determine which jars I'll need, and thus should include in my pom.xml file (I'm using maven as my project management tool)? When learning spring, to keep things simple, added all the jars (even the ones I never used) to the classpath. Right now for the most part, I'm guessing which jars to include. For example, I know in my spring configuration file, I have: <tx:annotation-driven /> <context:annotation-config /> <aop:aspectj-autoproxy /> So, I guess I'll need: spring-context-x.x.x.jar, spring-tx-x.x.x.jar, spring-aop-x.x.x.jar Thanks.

  • How to use a Spring config file in a Maven dependency

    - by javamonkey79
    In dependency A I have the following: <beans> <bean id="simplePersonBase" class="com.paml.test.SimplePerson" abstract="true"> <property name="firstName" value="Joe" /> <property name="lastName" value="Smith" /> </bean> </beans> And then in project B, I add A as a dependency and have the following config: <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd"> <bean id="simplePersonAddress01" parent="simplePersonBase"> <property name="firstName" value="BillyBob" /> <property name="address" value="1060 W. Addison St" /> <property name="city" value="Chicago" /> <property name="state" value="IL" /> <property name="zip" value="60613" /> </bean> </beans> When I use ClassPathXmlApplicationContext like so: BeanFactory beanFactory = new ClassPathXmlApplicationContext( new String[] { "./*.xml" } ); SimplePerson person = (SimplePerson)beanFactory.getBean( "simplePersonAddress01" ); System.out.println( person.getFirstName() ); Spring complains as it can not resolve the parent xml. Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'simplePersonBase' is defined I am sure there is a way to do this, however, I have not found it. Does anyone know how?

  • Does Hibernate 3.5.0-CR-2 release support JPA2.0

    - by fool
    I see that Hibernate home page has a symbol informing that it implements JSR 317, but I couldn't find if it implements the full spec.

  • Generate webservice soap client from wsdl when server using Windows Integrated Authentication

    - by James Black
    There is an SAP server that has some webservices I need to use, so I am trying to use wsimport to generate the client stubs. I don't want to find all the wsdls and schemas that are referenced and modify them to do it locally, as that isn't sustainable, if they service should change. So, how can I use wsimport to fetch a wsdl and generate the client stubs when the server is using Windows Integrated Authentication, where even the wsdl requires credentials.

  • Is there anyway I can fix a webview?

    - by Legend
    I am trying to load a webpage into a sample webview that I created: public class HelloWebview extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); WebView webview; webview = (WebView) findViewById(R.id.webview); webview.getSettings().setDefaultZoom(ZoomDensity.FAR); webview.setHorizontalScrollBarEnabled(false); webview.setVerticalScrollBarEnabled(false); webview.getSettings().setJavaScriptEnabled(true); webview.loadUrl("http://10.0.2.2/index.html"); } } Initially, I had a problem with the scrollbars so I added the two lines to disable them. Now, I am still able to pan around the webpage though the scroll bars are not visible. How can I fix the view so that I am not able to pan (or scroll) the webpage? By panning, I mean moving around the webpage with an onTouch event.

  • Displaying images in a console application?!

    - by Stefan Kendall
    I have a console application which screen scrapes some data, and now I need to do image comparisons. If the images are different, I want to show the images to the user. What's the best way to display two images during the execution of a console application? I'm assuming I would use some sort of inter-process communication to send information back and forth, but I'm not sure how exactly I would go about doing that in a good fashion. Also, I'd rather NOT store the images to files if possible. There's no reason to persist the data, and if the console application terminates unexpectedly, it's better if I don't have any dirt left on the file system. Does anyone have any thoughts on how best to accomplish this?

  • JBoss ignores @RemoteBinding annotation

    - by tputkonen
    I would like to specify JNDI name for an EJB3 bean using annotation, but JBoss 5.1.0 GA seems to ignore the annotation completely. Bean's annotations are: @Remote(Foobar.class) @Stateless(name = "Foobar") @TransactionManagement(TransactionManagementType.BEAN) @RemoteBinding(jndiBinding="ejb/Foobar") public class FoobarBean implements Foobar { ... I tested deploying also using @RemoteBindings annotation, but the result was same: @RemoteBindings({@RemoteBinding(jndiBinding="ejb/Foobar")}) The bean does not get bound to JNDI with the specified name, and the log file doesn't give any clues.

  • IVR-style dialog system

    - by unbeli
    I need to build a dialog system similar to IVR used in call centers. My system is not phone-based, but the dialog is similar. Something like System: "Main menu: Enter [1] for menu1, [2] for menu2" User: [1] System: "menu1: enter [1] for apples, [2] for oranges, [3] for main menu" User: [7] System: "What??" System: "menu1: enter [1] for apples, [2] for oranges, [3] for main menu" User: [2] ... and so on I want to have a nice declarative description of all the possible options and a nice way to run through that tree, guided by user input. Already considered: ANTLR-generated lexer/parser (seems to be an overkill), SCXML-based state machine (seems like only transitions can be declared, the rest needs to be coded)

  • JSON URL from StackExchange API returning jibberish?

    I have a feeling I'm doing something wrong here, but I'm not quite sure I'f I'm missing a step, or am just having an encoding problem or something. Here's my code URL url = new URL("http://api.stackoverflow.com/0.8/questions/2886661"); BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream())); // Question q = new Gson().fromJson(in, Question.class); String line; StringBuffer content = new StringBuffer(); while ((line = in.readLine()) != null) { content.append(line); } when I print content, I get a whole bunch of wingdings and special characters, basically jibberish. I would copy and past it here, but that isn't working. What am I doing wrong?
