  • How to get descriptive error messages from DB2?

    - by tangens
    When I call a SQL statement via JDBC on the DB2 and the statement fails, I catch an SQLException with the following message text: com.ibm.db2.jcc.a.nn: DB2 SQL Error: SQLCODE=-206, SQLSTATE=42703, SQLERRMC=O.METADATENSATZ, DRIVER=3.52.95 I tried an automatic translation of the message according to the error list published by IBM, but there are placeholders inside the messages referencing other elements of the exception. While looking for these elements inside the exception, I found the DB2ExceptionFormatter and tried to use it to access the missing elements. But here I stopped, because the DB2ExceptionFormatter gave me a clue: Error occurred while trying to obtain message text from server. Only message tokens are available. So my question is: What do I have to configure to get the correct messages from the DB2 server? If I can get a human readable message from the server, I could use it directly and wouldn't have to translate it by myself.

  • Android: How to prevent image from being scaled in ImageView or ImageButton?

    - by user277827
    Hi, How can I prevent my bitmap from being scaled automatically in an ImageView or ImageButton if the view or button is stretched using "fill_parent" or using "weight"? This will be useful, for example, to create a 4-button toolbar at the top of the screen where the buttons are equally spaced, but the images inside the buttons keep getting streched even if I use scaleType="center", which should prevent scaling according to the doc, but it doesn't. Any insight is appreciated! Thanks,

  • Adding a Layout to bottom of the screen inside a ScrollView in Landscape mode

    - by andreea
    I have the following layout which works in Portrait mode: the Layout with the id LinearLayout02 is placed at the bottom of the screen. The problem appears when flipping to Lanscape mode, when the #LinearLayout02 is placed at the top of the screen. The question is how do I position #LinearLayout02 at the bottom of the screen in both Portrait and Landscape mode? (This happens on G1 and Xperia) Thank you The following code is placed inside a ScrollView android:layout_height="fill_parent" android:layout_width="fill_parent" android:fillViewport="true" <LinearLayout android:id="@+id/sLayout" android:layout_height="wrap_content" android:layout_width="fill_parent" android:orientation="vertical" android:paddingTop="2dip" android:layout_alignParentTop="true" android:gravity="top" > ..... </LinearLayout> <LinearLayout android:id="@+id/LinearLayout02" android:background="@drawable/bottombar_bg" android:layout_width="fill_parent" android:paddingTop="10dip" android:layout_height="56dip" android:layout_alignParentBottom="true" android:gravity="bottom" > <Button android:id="@+id/navigate" style="@style/mainBottomTabsButtonNormal" android:drawableLeft="@drawable/icon_navigation" android:text="@string/navigationSettings" android:layout_gravity="left"> </Button> <Button android:id="@+id/search" style="@style/mainBottomTabsButtonActive" android:drawableLeft="@drawable/icon_search" android:text="@string/search.label" android:layout_gravity="right"> </Button> </LinearLayout> </RelativeLayout>

  • Blackberry Eclispe plugin and emulator

    - by gmcalab
    So I installed the following installation packages to develop Blackberry apps using the included emulators. I first installed them on a macbook pro, virtualizing windows 7 x86 with vmware. Everything worked fine, I created a quick HelloWorld app and it compiled and fully ran in the emulator. I did no other configuration. So I went to install this on my desktop PC with Windows 7 x64. I installed the exact same items. When I choose to run with the Blackberry Emulator, nothing happens. Any ideas? Here's the file list: BlackBerry_JDE_PluginFull_1.0.0.67 (This includes Eclispe) jdk-6u18-windows-i586

  • question about joGL (glTexImage2D)

    - by Nour
    Hi everybody I was trying to load a texture using joGL library but it seems that something is missing when using this method glTexImage2D at : IOStream wdis = new IOStream(fileName); wdis.skipBytes(18); int width = wdis.readIntW(); // dis.skipBytes(2); int height = wdis.readIntW(); // dis.skipBytes(2); wdis.skipBytes(28); byte buf[] = new byte[wdis.available()]; wdis.read(buf); wdis.close(); gl.glBindTexture(GL.GL_TEXTURE_2D, BMPtextures[index]); gl.glTexImage2D(GL.GL_TEXTURE_2D, 0, 3, width, height, 0, GL.GL_BGR, GL.GL_UNSIGNED_BYTE, buf); gl.glTexParameteri(GL.GL_TEXTURE_2D, GL.GL_TEXTURE_MAG_FILTER, GL.GL_LINEAR); gl.glTexParameteri(GL.GL_TEXTURE_2D, GL.GL_TEXTURE_MIN_FILTER, GL.GL_LINEAR); as IOStream is a class that extends DataInputStream it shows a message that glTexImage2D(int,int,int,int,int,int,int,int,byte[]) is not found at javax.media.opengl.GL I couldn't figure the problem her because it's an open source code and it seems to work perfectly with my friends but unfortunately not with me even though we are using the same library and the same JDK version what shall I do ??

  • How to paint fully transparent pixels/points in P2D mode?

    - by netzwerg
    According to the Processing Reference, stroke(gray, alpha) allows to set the color and opacity of the stroke. With the default color mode, an alpha value of 255 denotes full opacity, while a value of 0 should correspond to complete transparency. While this works with the (default) JAVA2D renderer, I can't seem to paint fully transparent points in P2D mode. This code clearly renders a pixel at the center of the canvas, even though the alpha value is set to 0 (fully transparent): public class Transparency extends PApplet { @Override public void setup() { size(200, 200, P2D); } @Override public void draw() { stroke(0, 0); point(width / 2, height / 2); } public static void main(String[] args) { PApplet.main(new String[] { Transparency.class.getSimpleName() }); } } What's wrong here?

  • Why does my Sax Parser produce no results after using InputStream Read?

    - by Andy Barlow
    Hello, I have this piece of code which I'm hoping will be able to tell me how much data I have downloaded (and soon put it in a progress bar), and then parse the results through my Sax Parser. If I comment out basically everything above the //xr.parse(new InputSource(request.getInputStream())); line and swap the xr.parse's over, it works fine. But at the moment, my Sax parser tells me I have nothing. Is it something to do with is.read (buffer) section? Also, just as a note, request is a HttpURLConnection with various signatures. /*Input stream to read from our connection*/ InputStream is = request.getInputStream(); /*we make a 2 Kb buffer to accelerate the download, instead of reading the file a byte at once*/ byte [ ] buffer = new byte [ 2048 ] ; /*How many bytes do we have already downloaded*/ int totBytes,bytes,sumBytes = 0; totBytes = request.getContentLength () ; while ( true ) { /*How many bytes we got*/ bytes = is.read (buffer); /*If no more byte, we're done with the download*/ if ( bytes <= 0 ) break; sumBytes+= bytes; Log.v("XML", sumBytes + " of " + totBytes + " " + ( ( float ) sumBytes/ ( float ) totBytes ) *100 + "% done" ); } /* Parse the xml-data from our URL. */ // OLD, and works if comment all the above //xr.parse(new InputSource(request.getInputStream())); xr.parse(new InputSource(is)) /* Parsing has finished. */; Can anyone help me at all?? Kind regards, Andy

  • Map enum in JPA with fixed values ?

    - by Kartoch
    I'm looking for the different ways to map an enum using JPA. I especially want to set the integer value of each enum entry and to save only the integer value. @Entity @Table(name = "AUTHORITY_") public class Authority implements Serializable { public enum Right { READ(100), WRITE(200), EDITOR (300); private int value; Right(int value) { this.value = value; } public int getValue() { return value; } }; @Id @GeneratedValue(strategy = GenerationType.AUTO) @Column(name = "AUTHORITY_ID") private Long id; // the enum to map : private Right right; } A simple solution is to use the Enumerated annotation with EnumType.ORDINAL: @Column(name = "RIGHT") @Enumerated(EnumType.ORDINAL) private Right right; But in this case JPA maps the enum index (0,1,2) and not the value I want (100,200,300). Th two solutions I found do not seem simple... First Solution A solution, proposed here, uses @PrePersist and @PostLoad to convert the enum to an other field and mark the enum field as transient: @Basic private int intValueForAnEnum; @PrePersist void populateDBFields() { intValueForAnEnum = right.getValue(); } @PostLoad void populateTransientFields() { right = Right.valueOf(intValueForAnEnum); } Second Solution The second solution proposed here proposed a generic conversion object, but still seems heavy and hibernate-oriented (@Type doesn't seem to exist in JEE): @Type( type = "org.appfuse.tutorial.commons.hibernate.GenericEnumUserType", parameters = { @Parameter( name = "enumClass", value = "Authority$Right"), @Parameter( name = "identifierMethod", value = "toInt"), @Parameter( name = "valueOfMethod", value = "fromInt") } ) Is there any other solutions ? I've several ideas in mind but I don't know if they exist in JPA: use the setter and getter methods of right member of Authority Class when loading and saving the Authority object an equivalent idea would be to tell JPA what are the methods of Right enum to convert enum to int and int to enum Because I'm using Spring, is there any way to tell JPA to use a specific converter (RightEditor) ?

  • Websphere MQ using JMS, closed connections stuck on the MQ

    - by Ahmad
    I have a simple JMS application deployed on OC4J under AIX server, in my application I'm listening to some queues and sending to other queues on a Websphere MQ deployed under AS400 server. The problem is that my connections to these queues are terminated/closed when it stays idle for some time with the error MQJMS1016 (this is not the problem), and when that happens I attempt to recover the connection and it works, however, the old connection is stuck at the MQ and would not terminate until it is terminated manually. The recovery code goes as follows: public void recover() { cleanup(); init(); } public void cleanup(){ if (session != null) { try { session .close(); } catch (JMSException e) { } } if (connection != null) { try { connection.close(); } catch (JMSException e) { } } } public void init(){ // typical initialization of the connection, session and queue... }

  • ScrollView alawys scrolling to the bottom

    - by Sebi
    I defined a scrollview with a texteedit in my layout: <ScrollView android:fillViewport="true" android:layout_marginBottom="50dip" android:id="@+id/start_scroller" android:layout_height="fill_parent" android:layout_width="fill_parent" android:fadingEdge="none"> <TextView android:id="@+id/text" android:layout_width="fill_parent" android:layout_height="wrap_content" > </TextView> </ScrollView> I add text to this ScrollView with the following method: public void writeToLogView(String textMsg) { if (text.getText().equals("")) { text.append(textMsg); } else { text.append("\n" + textMsg); scroller.scrollBy(0, 1000000); } } As you can see i append the text and try to scroll to the bottom of the ScrollView. Unfortunately this doesn't worked correctly. It scrolls down, but not always, and not always to the bottom. Any hints?

  • Joda-Time: DateTime, DateMidnight and LocalDate usage

    - by fraido
    Joda-Time library includes different datetime classes DateTime - Immutable replacement for JDK Calendar DateMidnight - Immutable class representing a date where the time is forced to midnight LocalDateTime - Immutable class representing a local date and time (no time zone) I'm wondering how are you using these classes in your Layered Applications. I see advantages in having almost all the Interfaces using LocalDateTime (at the Service Layer at least) so that my Application doesn't have to manage Timezones and can safely assume Times always in UTC. My app could then use DateTime to manage Timezones at the very beginning of the Execution's Flow. I'm also wondering in which scenario can DateMidnight be useful.

  • Exercise 26 of The Pragmatic Programmer

    - by _ande_turner_
    There is a code snippet presented in The Pragmatic Programmer on page 143 as: public class Colada { private Blender myBlender; private Vector myStuff; public Colada() { myBlender = new Blender(); myStuff = new Vector(); } private doSomething() { myBlender.addIngredients(myStuff.elements()); } } This obeys the Law of Demeter / Principle of Least Knowledge. Is it preferable to, and are there any caveats for, replacing it with the following, which utilises Dependency Injection? public class Colada throws IllegalArgumentException { private Blender myBlender; private Vector myStuff; public Colada(Blender blender, Vector stuff) { blender == null ? throw new IllegalArgumentException() : myBlender = blender; stuff == null ? throw new IllegalArgumentException() : myStuff = stuff; } public getInstance() { Blender blender = new Blender(); Vector stuff = new Vector(); return new Colada(blender, stuff); } private doSomething() { myBlender.addIngredients(myStuff.elements()); } }

  • JAXB: How to avoid repeated namespace definition for xmlns:xsi

    - by sfussenegger
    I have a JAXB setup where I use a @XmlJavaTypeAdapter to replace objects of type Person with objects of type PersonRef that only contains the person's UUID. This works perfectly fine. However, the generated XML redeclares the same namespace (xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance") every time it's used. While this is generally okay, it just doesn't feel right. How can I configure JAXB to declare xmlns:xsi at the very beginning of the document? Can I manually add namespace declarations to the root element? Here's an example of what I want to achive: Current: <person uuid="6ec0cf24-e880-431b-ada0-a5835e2a565a"> <relation type="CHILD"> <to xsi:type="personRef" uuid="56a930c0-5499-467f-8263-c2a9f9ecc5a0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/> </relation> <relation type="CHILD"> <to xsi:type="personRef" uuid="6ec0cf24-e880-431b-ada0-a5835e2a565a" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"/> </relation> <!-- SNIP: some more relations --> </person> Wanted: <person uuid="6ec0cf24-e880-431b-ada0-a5835e2a565a" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <relation type="CHILD"> <to xsi:type="personRef" uuid="56a930c0-5499-467f-8263-c2a9f9ecc5a0"/> </relation> <relation type="CHILD"> <to xsi:type="personRef" uuid="6ec0cf24-e880-431b-ada0-a5835e2a565a"/> </relation> <!-- SNIP: some more relations --> </person>

  • blackberry mainscreen vertical scroll

    - by pajton
    I am trying to create a MainScreen with vertical scrolling. From what I've read in the documentation, MainScreen has a VerticalManager inside, so it should be possible to enable vertical scrolling only with proper construction, i.e: super(MainScreen.VERTICAL_SCROLL | MainScreen.VERTICAL_SCROLLBAR); This is not working for me, however. I am creating a screen, adding a couple of LabelFields and no scrollbar, no scrolling at all. I am testing on 8900, OS 5.0. Here is the code I use: public class ExampleScreen extends MainScreen { public ExampleScreen() { super(MainScreen.VERTICAL_SCROLL | MainScreen.VERTICAL_SCROLLBAR); create(); } private void add(String text) { add(new LabelField(text)); } private void create() { add("line 0"); add("line 1"); ... etc ... } } The question is am I doing something wrong? Is there a way to enable vertical scrolling with MainScreen or do I need to create a VerticalManager myself?

  • Using Apache Camel how do I unmarshal my deserialized object that comes in through a CXF Endpoint?

    - by ScArcher2
    I have a very simple camel route. It starts with a CXF Endpoint exposed as a web service. I then want to convert it to xml and call a method on a bean. Currently i'm getting a CXF specific object after the web service call. How do I take my serialized object out of the CXF MessageList and use it going forward? My Route: <camel:route> <camel:from uri="cxf:bean:helloEndpoint" /> <camel:marshal ref="xstream-utf8" /> <camel:to uri="bean:hello?method=hello"/> </camel:route> The XML Serialized Message: <?xml version='1.0' encoding='UTF-8'?> <org.apache.cxf.message.MessageContentsList serialization="custom"> <unserializable-parents /> <list> <default> <size>1</size> </default> <int>6</int> <com.whatever.Person> <firstName>Joe</firstName> <middleName></middleName> <lastName>Buddah</lastName> <dateOfBirth>2010-04-13 12:09:00.137 CDT</dateOfBirth> </com.whatever.Person> </list> </org.apache.cxf.message.MessageContentsList> I would expect the XML to be more like this: <com.whatever.Person> <firstName>Joe</firstName> <middleName></middleName> <lastName>Buddah</lastName> <dateOfBirth>2010-04-13 12:09:00.137 CDT</dateOfBirth> </com.whatever.Person>

  • Intercepting method with Spring AOP using only annotations

    - by fish
    In my Spring context file I have something like this: <bean id="userCheck" class="a.b.c.UserExistsCheck"/> <aop:config> <aop:aspect ref="userCheck"> <aop:pointcut id="checkUser" expression="execution(* a.b.c.d.*.*(..)) &amp;&amp; args(a.b.c.d.RequestObject)"/> <aop:around pointcut-ref="checkUser" method="checkUser"/> </aop:aspect> </aop:config> a.b.c.UserExistsCheck looks like this: @Aspect public class UserExistsCheck { @Autowired private UserInformation userInformation; public Object checkUser(ProceedingJoinPoint pjp) throws Throwable { int userId = ... //get it from the RequestObject passed as a parameter if (userExists(userId)) { return pjp.proceed(); } else { return new ResponseObject("Invalid user); } } And the class that is being intercepted with this stuff looks like this: public class Klazz { public ResponseObject doSomething(RequestObject request) {...} } This works. UserExistCheck is executed as desired before the call is passed to Klazz. The problem is that this is the only way I got it working. To get this working by using annotations instead of the context file seems to be just too much for my small brain. So... how exactly should I annotate the methods in UserExistsCheck and Klazz? And do I still need something else too? Another class? Still something in the context file?

  • Web service request ignores basic WSDL XML element restrictions

    - by Oliver
    Hi all, I have encountered some difficulties while trying to validate an incoming soap message to a service I have running on JBoss AS (v. 5.1.0). In my code, I have explicitly set some fields to be required, eg: public class MyClass { @XmlElement(required=true, nillable=false) private List<myOtherObjects> myList; } This requirement is also reflected in the WSDL (note the lack of minOccurs="0"): <xs:element maxOccurs="unbounded" name="myList" type="tns:myOtherObjects" /> However, when I do a test soap message that has myList set to empty or null, these restrictions are completely ignored, forcing me to validate manually within the application logic on the service. I did some searching on the Internet and found out that, on WebLogic, the validation does not seem to be enabled by default, though it can be turned on by modifying the weblogic-webservices.xml file. (http://forums.oracle.com/forums/thread.jspa?threadID=783972&tstart=115) I’m wondering if there is something similar that I have to do with JBoss AS to enable automatic validation before the soap message reaches the service. Any help would be greatly appreciated. Oliver

  • Swipe gestures on Android ListView items

    - by Bartek
    I have a ListView populated by a ResourceCursorAdapter. I use the loaders mechanism to query a ContentProvider for list items. I detect swipe gestures on the list items to perform some actions on them. New items get added by a background service, so the list can change dynamically. Everything works fine, except when I start swiping and a database change occurs (as a result of the background service adding a new row). In such case the gesture is not detected properly. I noticed that ACTION_CANCEL is dispatched to the list item view and also that bindView is executed for all visible items. Inside the bindView method I only set some text - I don't change any listeners there. How can I make gestures work even when new items are being added by the background service? Perhaps there's a way to prevent the motion from being cancelled or I can pause database updates so they don't interrupt the gesture.
