  • Hibernate generate POJOs with Equals

    - by jschoen
    We are using hibernate in a new project where we use the hibernate.reveng.xml to create our *.hbm.xml files and POJOs after that. We want to have equals methods in each of our POJOs. I found that you can use <meta attribute="use-in-equals">true</meta> in your hbm files to mark which properties to use in the equals. But this would mean editing alot of files, and then re-editing the files again in the future if/when we modify tables or columns in our DB. So I was wondering if there is a way to place which properties to use in the equals method for each pojo(table) in the hibernate.reveng.xml file?

  • Disabling JComboBox and retaining original item list

    - by n002213f
    My action listener on a JComboBox invokes a thread. I would like the component to be disabled until the thread completes. I have tried calling seEnabled(false) when the thread start and setEnabled(true) when it completes. Unfortunately setEnabled(false) clears the combo box list as well. Is there a way of disabling the component but retain the original list?

    Hi guys, I solved a problem recently. But I have this one piece of code where I dont utilize the for loop initialization and condition check. It looks a bit odd that way for a for loop. I want to convert it into a while loop. Please help me do it. I tried many times, but somewhere something is missing. for(;;current =(current+1)%n){ if(eliminated[current%n]){ continue; }else{ inkiPinki++; if(inkiPinki == m){ eliminated[current%n] = true; printStatus(eliminated, people); remainingGuys--; break; } } } In the above code eliminiated[index] is a boolean.

Moreover at Jboss 4.2.2 application is working fine up to long -long html element. I set content type as: <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> This issue is reproducible at FF 3.6 and IE 7 and 8 browser. Can anyone help me out? Am I missing some setting?

  • NotFoundException in layout editor for Android?

    - by borg17of20
    I'm trying to extend a RelativeLayout object and include an embedded SurfaceView object that uses a png file in my /res/drawable folder as its background but I keep getting an error in the XML Layout editor. See the following code: public class StopMotionRelativeLayout extends RelativeLayout { private Context myContext; private SurfaceView surfaceView1; private BitmapFactory.Options myBitmapOptions; private final android.view.ViewGroup.LayoutParams params = new LayoutParams(LayoutParams.FILL_PARENT, android.view.ViewGroup.LayoutParams.FILL_PARENT); public StopMotionRelativeLayout(Context context, AttributeSet attrs) { super(context, attrs); myContext = context; this.setBackgroundColor(Color.GREEN); //init images surfaceView1 = new SurfaceView(myContext,attrs); surfaceView1.setVisibility(View.INVISIBLE); this.addView(surfaceView1, params); } @Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { super.onMeasure(widthMeasureSpec, heightMeasureSpec); myBitmapOptions = new Options(); myBitmapOptions.outWidth = widthMeasureSpec; myBitmapOptions.outHeight = heightMeasureSpec; surfaceView1.setBackgroundDrawable(new BitmapDrawable(BitmapFactory.decodeResource(this.myContext.getResources(), R.drawable.golf1, myBitmapOptions))); } } I get the following error: NotFoundException: Could not find drawable resource matching value 0x7F020002 (resolved name: golf1) in current configuration. I have seen this type of error may times now and it always happens when I try to load something from a resource file via code and not XML. Curiously, this error does not stop me from compiling the app, and the app runs without error in the emulator. I'd like to get back the use of my layout editor though... Please help. UPDATE: Here is the layout XML <?xml version="1.0" encoding="utf-8"?> <com.games.test.StopMotionRelativeLayout android:id="@+id/RelativeLayout01" android:layout_width="fill_parent" android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android"> </com.games.test.StopMotionRelativeLayout>

    I'm trying to figure out how to use HTTPClient (org.eclipse.jetty.client.HttpClient) so it will pipeline HTTP Request. I've tried to create some HttpExchange instances and applying the send() method for each, in an asynchronous mode, but each HTTP request has waited for it response before the next request was sent. Can you please supply a code snippet for this case?

  • Looking for detailed explanation of Hibernate UserType methods for mutable objects

    - by Tom
    I am creating a custom UserType class in Hibernate. The specific case is for an HL7v3 clinical document (I work in health IT). It is a mutable object and most of the documentation around the Hibernate UserType interface seems to center around immutable types. I want a better understanding of how and when the interface methods are used, specifically: assemble - why two parameters (one Serializable, one Object)? What is the use case for this method? disassemble - should I just implement this method to return a serializable form (e.g. String representation)? When and how is this method invoked? equals - is this for update? read? contention? dirty reads? What are the consequences of simply returning false in most cases? replace - I really don't understand where the three Object parameters come from, when this method is invoked, and what Hibernate expects to return, or how that return value is used. Any pointers would be appreciated. I've searched and read all I can find on the subject, but have not found much documentation at all explaining how these methods are used for mutable objects.

  • Maven Release Plugin with JAXB issues

    - by Wysawyg
    Hiya, We've got a project set up to use the Maven Release Plugin which includes a phase that unpacks a JAR of XML schemas pulled from Artifactory and a phase that generates XJC classes. We're on maven release 2.2.1. Unfortunately the latter phase is executing before the former which means that it isn't generating the XJC classes for the schema. A partial POM.XML looks like: <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.6</source> <target>1.6</target> </configuration> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-dependency-plugin</artifactId> <executions> <execution> <id>unpack</id> <!-- phase>generate-sources</phase --> <goals> <goal>unpack</goal> <goal>copy</goal> </goals> <configuration> <artifactItems> <artifactItem> <groupId>ourgroupid</groupId> <artifactId>ourschemas</artifactId> <version>5.1</version> <outputDirectory>${project.basedir}/src/main/webapp/xsd</outputDirectory> <excludes>META-INF/</excludes> <overWrite>true</overWrite> </artifactItem> </artifactItems> </configuration> </execution> </executions> </plugin> <plugin> <groupId>org.codehaus.mojo</groupId> <artifactId>maven-buildnumber-plugin</artifactId> <version>0.9.6</version> <executions> <execution> <phase>validate</phase> <goals> <goal>create</goal> </goals> </execution> </executions> <configuration> <doCheck>true</doCheck> <doUpdate>true</doUpdate> </configuration> </plugin> <plugin> <groupId>org.jvnet.jaxb2.maven2</groupId> <artifactId>maven-jaxb2-plugin</artifactId> <configuration> <schemaDirectory>${project.basedir}/src/main/webapp/xsd</schemaDirectory> <schemaIncludes> <include>*.xsd</include> <include>*/*.xsd</include> </schemaIncludes> <verbose>true</verbose> <!-- args> <arg>-Djavax.xml.validation.SchemaFactory:http://www.w3.org/2001/XMLSchema=org.apache.xerces.jaxp.validation.XMLSchemaFactory</arg> </args--> </configuration> <executions> <execution> <goals> <goal>generate</goal> </goals> </execution> </executions> </plugin> I've tried googling for it, unfortunately I ended up with a case of thousands of links none of which were actually relevant so I'd be very grateful if someone knew how to configure the order of the release plugin steps to ensure a was fully executed before it did b. Thanks

  • Issues with reversing bit shifts that roll over the maximum byte size?

    - by Terri
    I have a string of binary numbers that was originally a regular string and will return to a regular string after some bit manipulation. I'm trying to do a simple caesarian shift on the binary string, and it needs to be reversable. I've done this with this method.. public static String cShift(String ptxt, int addFactor) { String ascii = ""; for (int i = 0; i < ptxt.length(); i+=8) { int character = Integer.parseInt(ptxt.substring(i, i+8), 2); byte sum = (byte) (character + addFactor); ascii += (char)sum; } String returnToBinary = convertToBinary(ascii); return returnToBinary; } This works fine in some cases. However, I think when it rolls over being representable by one byte it's irreversable. On the test string "test!22*F ", with an addFactor of 12, the string becomes irreversible. Why is that and how can I stop it?

  • Why does XPath.selectNodes(context) always use the whole document in JDOM

    - by Simeon
    Hi, I'm trying to run the same query on several different contexts, but I always get the same result. This is an example xml: <root> <p> <r> <t>text</t> </r> </p> <t>text2</t> </root> So this is what I'm doing: final XPath xpath = XPath.newInstance("//t"); List<Element> result = xpath.selectNodes(thisIsThePelement); // and I've debuged it, it really is the <p> element And I always get both <t> elements in the result list. I need just the <t> inside the <p> I'm passing to the XPath object. Any ideas would be of great help, thanks.

  • JFrame not working correctly

    - by Nick Gibson
    This is making me very angry, I have worked on this for 2 days, have 2 books open and have looked through them, and STILL can't get this program to run the way I want it run. I'm getting to the point where if this doesn't help, I quit. I want a SIMPLE Frame application. It has a JComboBox centered at the top. Next to it is a text field big enough to show numeric digits such as "$49.99" Below it is a spot for a Text area showing terms of service Below that is the checkbox agreeing to the terms of service Below that is 2 buttons "Accept" and "Decline" I Have worked on this for 2 days, here is the coding: public class Bar extends JFrame implements ActionListener { public Bar(final JFrame frame) { String[] tests = { "A+ Certification", "Network+ Certification", "Security+ Certification", "CIT Full Test Package" }; JButton button = new JButton("Click Meh"); add(new JLabel("Welcome to the CIT Test Program ")); add(new JLabel("Please select which Test Package from the list below.")); frame.setVisible(true); frame.setSize(250,250); JPanel pane1 = new JPanel(new FlowLayout()); JPanel pane2 = new JPanel(new FlowLayout()); JMenuBar menuBar = new JMenuBar(); JMenu fileMenu = new JMenu("File"); JMenu editMenu = new JMenu("Edit"); JMenu helpMenu = new JMenu("Help"); menuBar.add(fileMenu); menuBar.add(editMenu); menuBar.add(helpMenu); JMenuItem newMenu = new JMenuItem("New (Ctrl+N)"); JMenuItem openMenu = new JMenuItem("Open (Ctrl+O)"); JMenuItem saveMenu = new JMenuItem("Save (Ctrl+S)"); saveMenu.addActionListener(this); JMenuItem exitMenu = new JMenuItem("Exit (Ctrl+W)"); JMenuItem cutMenu = new JMenuItem("Cut (Ctrl+X)"); JMenuItem copyMenu = new JMenuItem("Copy (Ctrl+C)"); JMenuItem pasteMenu = new JMenuItem("Paste (Ctrl+V)"); JMenuItem infoMenu = new JMenuItem("Help (Ctrl+H)"); fileMenu.add(newMenu); fileMenu.add(openMenu); fileMenu.add(saveMenu); fileMenu.add(exitMenu); editMenu.add(cutMenu); editMenu.add(copyMenu); editMenu.add(pasteMenu); helpMenu.add(infoMenu); frame.setJMenuBar(menuBar); JComboBox packageChoice = new JComboBox(tests); frame.add(packageChoice); } public void actionPerformed(ActionEvent e) { Object source = e.getSource(); { } } EDIT: Forgot to add the second program public class JFrameWithPanel { public static void main(String[] args) { JPanel panel = new Bar(new JFrame("CIT Test Program")); } } How do I get this to have everything where I want it and show up? I'm very confused because of this and now barely even get how Frames work.

  • Playing around with Eclipse features - Project files are now hidden?

    - by Daddy Warbox
    I don't even remember how, but somehow I managed to make all of my project's source files hidden in Eclipse's Package and Project Explorer panels. Go figure. 'Show Filtered Children (alt+click)' temporarily reveals the files, and only in Package Explorer can I double-click to reopen them from this view. They go back into hiding after I select another item, though. Plus, now I'm getting other annoyances, such as all of the folded non-hidden trees altogether expanding when I click on any item, and the entire file folder tree of my project now being shown in these panels (including my .svn subversion folders... which shouldn't be any of Eclipse's business, presently). Long story short, my Package/Project Explorers' just blew up on me, and I want to know how to fix this. Thanks in advance. P.S. What's a good guide I can use to learn my way around this silly contraption, anyway?

  • append files to an archive without reading/rewriting the whole archive

    - by bene
    I've got many files that I want to store in a single archive file. My first approach was to store the files in a gzipped tarball. The problem is, that I've to rewrite the whole archive if a single file is added. I could get rid of the gzip compression, but adding a file would still be expensive. What other archive format would you suggest that allows fast append operations?

  • How to set JtextArea to keep fixed no of rows?

    - by Hippo
    How can i keep no of rows constant in text area. I need to create a console window for my application. If rows exceeds predefined no of rows first rows must get disposed. As if first written row will be destroyed first when i append anything which exceeds no of rows set. One more thing , i need to keep vertical scroll bar. That means no of rows must not be the whatever rows are visible when text area it opened. For example : - no of visible rows on view port are 30. It should keep 120 rows information, which will can be seen with the help of scroll bar.

  • HQL query for entity with max value

    - by Rob
    I have a Hibernate entity that looks like this (accessors ommitted for brevity): @Entity @Table(name="FeatureList_Version") @SecondaryTable(name="FeatureList", pkJoinColumns=@PrimaryKeyJoinColumn(name="FeatureList_Key")) public class FeatureList implements Serializable { @Id @Column(name="FeatureList_Version_Key") private String key; @Column(name="Name",table="FeatureList") private String name; @Column(name="VERSION") private Integer version; } I want to craft an HQL query that retrieves the most up to date version of a FeatureList. The following query sort of works: Select f.name, max(f.version) from FeatureList f group by f.name The trouble is that won't populate the key field, which I need to contain the key of the record with the highest version number for the given FeatureList. If I add f.key in the select it won't work because it's not in the group by or an aggregate and if I put it in the group by the whole thing stops working and it just gives me every version as a separate entity. So, can anybody help?
