  • Unresolved compilation problems -- can't use .jar files that I have created

    - by Mike
    I created a few .jar files and am trying to access them in another application - I have tried to use both Eclipse and IntelliJ and experience the same issue: java.lang.Error: Unresolved compilation problems: The import com.XXXX.XXXXXXXXX.project2 cannot be resolved The import com.XXXX.XXXXXXXXX.project2 cannot be resolved BeanFactory cannot be resolved to a type Author cannot be resolved to a type AuthorFactoryImpl cannot be resolved to a type Author cannot be resolved to a type Author cannot be resolved to a type I have been using Maven during this process and the jars compile fine. I have included them on the file path using both the Maven .pom file and directly assigning them. I also have unassigned the direct file path and left the reference in Maven and vise versa -- no difference. See below .jar file class info: file structure: Author.java BeanWithIdentityInterface Books Subject ie: Interface: package com.XXXX.training; /** * Created with IntelliJ IDEA. * User: kBPersonal * Date: 11/5/12 * Time: 3:16 PM * */ public interface BeanWithIdentityInterface <I> { I getId(); } Author.java: package com.XXXX.training; /** * Created with IntelliJ IDEA. * User: kBPersonal * Date: 10/25/12 * Time: 12:03 PM */ public class Author implements BeanWithIdentityInterface <Integer>{ private Integer id = null; private String name = null; private String picture = null; private String bio = null; public Author(Integer id, String bio, String name, String picture) { this.id = id; this.bio = bio; this.name = name; this.picture = picture; } public Author (){} @Override public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getPicture() { return picture; } public void setPicture(String picture) { this.picture = picture; } public String getBio() { return bio; } public void setBio(String bio) { this.bio = bio; } @Override public String toString() { return "\n\tAuthor Id: "+this.getId() + " | Bio:"+ this.getBio()+ " | Name:"+ this.getName()+ " | Picture: "+ this.getPicture(); } } implementing Servlet: package com.acentia.training.project3.controller; import com.acentia.training.*; import com.acentia.training.project2.AuthorFactoryImpl; import com.acentia.training.project2.BeanFactory; import javax.servlet.ServletException; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import java.io.IOException; import java.io.PrintWriter; /** * Created with IntelliJ IDEA. * User: kBPersonal * Date: 11/11/12 * Time: 6:34 PM * */ public class ListAuthorServlet extends AbstractBaseServlet { private static final long serialVersionUID = -6934109551750492182L; public void doProcess(final HttpServletRequest request, final HttpServletResponse response) throws IOException { final BeanFactory<Author, Integer> authorFactory = new AuthorFactoryImpl(); Author author = null; if (authorFactory != null) { author = (Author) authorFactory.getMember(5); } I can't pull the Author class.

  • Placing component on Glass Pane

    - by Chris Lieb
    I have a subclass of JLabel that forms a component of my GUI. I have implemented the ability to drag and drop the component from one container to another, but without any visual effects. I want to have this JLabel follow the cursor during the drag of the item from one container to another. I figured that I could just create a glass pane and draw it on there. However, even after I add the component to the glass pane, set the component visible, and set the glass pane visible, and set the glass pane as opaque, I still so not see the component. I know the component works because I can add it to the content pane and have it show up. How do I add a component to the glass pane? package wpics509s10t7.view; import javax.swing.*; import wpics509s10t7.model.Tile; import java.awt.*; import java.awt.dnd.DragSource; import java.awt.event.AWTEventListener; import java.awt.event.MouseEvent; /** * GlassPane tutorial * "A well-behaved GlassPane" * http://weblogs.java.net/blog/alexfromsun/ * <p/> * This is the final version of the GlassPane * it is transparent for MouseEvents, * and respects underneath component's cursors by default, * it is also friedly for other users, * if someone adds a mouseListener to this GlassPane * or set a new cursor it will respect them * * @author Alexander Potochkin */ public class GlassPane extends JPanel implements AWTEventListener { private static final long serialVersionUID = 1L; private final JFrame frame; private TileView tv; // subclass of JLabel private Point point; private WordStealApp wsa; public GlassPane(JFrame frame, WordStealApp wsa) { super(null); this.wsa = wsa; this.frame = frame; setOpaque(true); setLayout(null); setVisible(true); composite = AlphaComposite.getInstance(AlphaComposite.SRC_OVER, 0.5f); } public void beginDrag(Tile t, Point p) { this.tv = new TileView(t, null, this.wsa, true); this.add(this.tv); System.out.println("Starting point: x=" + p.getX() + ",y=" + p.getY()); this.tv.setLocation((int)p.getX(), (int)p.getY()); this.tv.setVisible(true); } public void endDrag(Point p) { System.out.println("Ending point: x=" + p.getX() + ",y=" + p.getY()); this.remove(this.tv); this.tv.setVisible(false); this.tv = null; } public void eventDispatched(AWTEvent event) { if (event instanceof MouseEvent) { MouseEvent me = (MouseEvent) event; if (!SwingUtilities.isDescendingFrom(me.getComponent(), frame)) { return; } if (me.getID() == MouseEvent.MOUSE_EXITED && me.getComponent() == frame) { if (tv != null) { tv.setVisible(false); } point = null; } else { MouseEvent converted = SwingUtilities.convertMouseEvent(me.getComponent(), me, frame.getGlassPane()); point = converted.getPoint(); } repaint(); } } /** * If someone adds a mouseListener to the GlassPane or set a new cursor * we expect that he knows what he is doing * and return the super.contains(x, y) * otherwise we return false to respect the cursors * for the underneath components */ @Override public boolean contains(int x, int y) { if (getMouseListeners().length == 0 && getMouseMotionListeners().length == 0 && getMouseWheelListeners().length == 0 && getCursor() == Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR)) { return false; } return super.contains(x, y); } }

  • GWT with JDO problem

    - by Maksim
    I just start playing with GWT I'm having a really hard time to make GWT + JAVA + JDO + Google AppEngine working with DataStore. I was trying to follow different tutorial but had no luck. For example I wend to these tutorials: TUT1 TUT2 I was not able to figure out how and what i need to do in order to make this work. Please look at my simple code and tell me what do i need to do so i can persist it to the datastore: 1.

  • Covariance and Contravariance in C#

    - by edalorzo
    I will start by saying that I am Java developer learning to program in C#. As such I do comparisons of what I know with what I am learning. I have been playing with C# generics for a few hours now, and I have been able to reproduce the same things I know in Java in C#, with the exception of a couple of examples using covariance and contravariance. The book I am reading is not very good in the subject. I will certainly seek more info on the web, but while I do that, perhaps you can help me find a C# implementation for the following Java code. An example is worth a thousand words, and I was hoping that by looking a good code sample I will be able to assimilate this more rapidly. Covariance In Java I can do something like this: public static double sum(List<? extends Number> numbers) { double summation = 0.0; for(Number number : numbers){ summation += number.doubleValue(); } return summation; } I can use this code as follows: List<Integer> myInts = asList(1,2,3,4,5); List<Double> myDoubles = asList(3.14, 5.5, 78.9); List<Long> myLongs = asList(1L, 2L, 3L); double result = 0.0; result = sum(myInts); result = sum(myDoubles) result = sum(myLongs); Now I did discover that C# supports covariance/contravariance only on interfaces and as long as they have been explicitly declared to do so (out). I think I was not able to reproduce this case, because I could not find a common ancestor of all numbers, but I believe that I could have used IEnumerable to implement such thing if a common ancestor exists. Since IEnumerable is a covariant type. Right? Any thoughts on how to implement the list above? Just point me into the right direction. Is there any common ancestor of all numeric types? Contravariance The contravariance example I tried was the following. In Java I can do this to copy one list into another. public static void copy(List<? extends Number> source, List<? super Number> destiny){ for(Number number : source) { destiny.add(number); } } Then I could use it with contravariant types as follows: List<Object> anything = new ArrayList<Object>(); List<Integer> myInts = asList(1,2,3,4,5); copy(myInts, anything); My basic problem, trying to implement this in C# is that I could not find an interface that was both covariant and contravariant at the same time, as it is case of List in my example above. Maybe it can be done with two different interface in C#. Any thoughts on how to implement this? Thank you very much to everyone for any answers you can contribute. I am pretty sure I will learn a lot from any example you can provide.

  • How to code a time delay between plotting points in JFreeCharts?

    Is there a way to animate the plotting process of an xy-line chart using JFreeCharts? I want to be able to watch the program draw each line segment and connect them. For example, if I paste this into the TextArea, "gtgtaaacaatatatggcg," I want to watch it graph each line segment one by one.

    - by Xorty
    Hello, I am trying to use native MySQL's MD5 crypto func, so I defined custom insert in my mapping file. <hibernate-mapping package="tutorial"> <class name="com.xorty.mailclient.client.domain.User" table="user"> <id name="login" type="string" column="login"></id> <property name="password"> <column name="password" /> </property> <sql-insert>INSERT INTO user (login,password) VALUES ( ?, MD5(?) )</sql-insert> </class> </hibernate-mapping> Then I create User (pretty simple POJO with just 2 Strings - login and password) and try to persist it. session.beginTransaction(); // we have no such user in here yet User junitUser = (User) session.load(User.class, "junit_user"); assert (null == junitUser); // insert new user junitUser = new User(); junitUser.setLogin("junit_user"); junitUser.setPassword("junitpass"); session.save(junitUser); session.getTransaction().commit(); What actually happens? User is created, but with reversed parameters order. He has login "junitpass" and "junit_user" is MD5 encrypted and stored as password. What did I wrong? Thanks EDIT: ADDING POJO class package com.xorty.mailclient.client.domain; import java.io.Serializable; /** * POJO class representing user. * @author MisoV * @version 0.1 */ public class User implements Serializable { /** * Generated UID */ private static final long serialVersionUID = -969127095912324468L; private String login; private String password; /** * @return login */ public String getLogin() { return login; } /** * @return password */ public String getPassword() { return password; } /** * @param login the login to set */ public void setLogin(String login) { this.login = login; } /** * @param password the password to set */ public void setPassword(String password) { this.password = password; } /** * @see java.lang.Object#toString() * @return login */ @Override public String toString() { return login; } /** * Creates new User. * @param login User's login. * @param password User's password. */ public User(String login, String password) { setLogin(login); setPassword(password); } /** * Default constructor */ public User() { } /** * @return hashCode * @see java.lang.Object#hashCode() */ @Override public int hashCode() { final int prime = 31; int result = 1; result = prime * result + ((null == login) ? 0 : login.hashCode()); result = prime * result + ((null == password) ? 0 : password.hashCode()); return result; } /** * @param obj Compared object * @return True, if objects are same.

  • Does anyone know how to layout a JToolBar that does't move or re-size any components placed in it?

    - by S1.Mac
    Can anyone help with this problem i'm trying to create a JToolBar and I want all its components to be fixed in size and position. I'v tried a few different layout managers but they all center and/or re-size the components when the frame its in is re-sized. here is an example using GridbagLayout, I have also used the default layout manager using the toolbar.add( component ) method but the result is the same : ' import java.awt.BorderLayout; import java.awt.Component; import java.awt.Dimension; import java.awt.GridBagConstraints; import java.awt.GridBagLayout; import javax.swing.*; public class ToolBarTest extends JFrame { private JToolBar toolbar; private JPanel mainPanel; private JPanel toolBarPanel; private JButton aButton; private JCheckBox aCheckBox; private JList aList; private Box toolbarBox; private GridBagConstraints toolbarConstraints; private GridBagLayout toolbarLayout; private JLabel shapeLabel; private JComboBox<ImageIcon> shapeChooser; private JLabel colorLabel; private JComboBox colorChooser; private String colorNames[] = { "Black" , "Blue", "Cyan", "Dark Gray", "Gray", "Green", "Light Gray", "Magenta", "Orange", "Pink", "Red", "White", "Yellow", "Custom" }; private String shapeNames[] = { "Line", "Oval", "Rectangle", "3D Rectangle","Paint Brush", "Rounded Rectangle" }; public ToolBarTest() { setLayout( new BorderLayout() ); setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE ); setSize( 500, 500 ); add( createToolBar(), BorderLayout.PAGE_START ); setVisible( true ); } public void addToToolbar( Component component, int row, int column ) { toolbarConstraints.gridx = column; toolbarConstraints.gridy = row; toolbarConstraints.anchor = GridBagConstraints.WEST; toolbarConstraints.fill = GridBagConstraints.NONE; toolbarConstraints.weightx = 0; toolbarConstraints.weighty = 0; toolbarConstraints.gridwidth = 1; toolbarConstraints.gridheight = 1; toolbarLayout.setConstraints( component, toolbarConstraints ); toolbar.add( component ); }// end addToToolbar public final JToolBar createToolBar() { toolbarLayout = new GridBagLayout(); toolbarConstraints = new GridBagConstraints(); // create the tool bar which holds the items to draw toolbar = new JToolBar(); toolbar.setBorderPainted(true); toolbar.setLayout( toolbarLayout ); toolbar.setFloatable( true ); shapeLabel = new JLabel( "Shapes: " ); addToToolbar( shapeLabel, 0, 1 ); String iconNames[] = { "PaintImages/Line.jpg", "PaintImages/Oval.jpg", "PaintImages/Rect.jpg", "PaintImages/3DRect.jpg","PaintImages/PaintBrush.jpg", "PaintImages/RoundRect.jpg"}; ImageIcon shapeIcons[] = new ImageIcon[ shapeNames.length ]; // create image icons for( int shapeButton = 0; shapeButton < shapeNames.length; shapeButton++ ) { shapeIcons[ shapeButton ] = new ImageIcon( iconNames[ shapeButton ] ); }// end for shapeChooser = new JComboBox< ImageIcon >( shapeIcons ); shapeChooser.setSize( new Dimension( 50, 20 )); shapeChooser.setPrototypeDisplayValue( shapeIcons[ 0 ] ); shapeChooser.setSelectedIndex( 0 ); addToToolbar( shapeChooser, 0, 2 ); colorLabel = new JLabel( "Colors: " ); addToToolbar( colorLabel, 0, 3 ); colorChooser = new JComboBox( colorNames ); addToToolbar( colorChooser, 0, 4 ); return toolbar; }// end createToolBar public static void main( String args[] ) { new ToolBarTest(); }// end main }// end class ToolBarTest'

  • Not sure why I'm getting a NullPointerException when creating a Swing component

    - by Alex
    The error occurs when creating the Box object. public void drawBoard(Board board){ for(int row = 0; row < 8; row++){ for(int col = 0; col < 8; col++){ Box box = new Box(board.getSquare(col, row).getColour(), col, row); squarePanel[col][row].add(box); } } Board is given from the Game constructor here (another class): public Game() throws Throwable{ View graphics = new View(); board = new Board(); board.setDefault(); graphics.drawBoard(board); } The Board constructor looks like this: public Board(){ grid = new Square[COLUMNS][ROWS]; for(int row = 0; row < 8; row++){ for(int col = 0; col < 8; col++){ grid[col][row] = new Square(this); } } for(int row = 0; row < 8; row++){ for(int col = 0; col < 4; col++){ int odd = 2*col + 1; int even = 2*col; getSquare(odd, row).setColour(Color.BLACK); getSquare(even, row).setColour(Color.WHITE); } } } And finally the Box class: class Box extends JComponent{ Color boxColour; int col, row; public Box(Color boxColour, int col, int row){ this.boxColour = boxColour; this.col = col; this.row = row; repaint(); } public void paint(Graphics drawBox){ drawBox.setColor(boxColour); drawBox.drawRect(50*col, 50*row, 50, 50); drawBox.fillRect(50*col, 50*row, 50, 50); } } So while looping through the array, it uses the two integers as coordinates to create the Box. The coordinates are referenced and then repaint() is run. The box also gets the colour, using the two integers, from the Square in the Board class. Since the colour is already set, before the drawBoard(board) method is run, that shouldn't be a problem, right? Exception in thread "main" java.lang.NullPointerException at View.drawBoard(View.java:38) at Game.<init>(Game.java:21) at Game.main(Game.java:14) The relevant part of Square import java.awt.Color; public class Square { private Piece piece; private Board board; private Color squareColour; public Square(Board board){ this.board = board; } public void setColour(Color squareColour){ this.squareColour = squareColour; } public Color getColour(){ return squareColour; }

  • Using AsyncTask, but experiencing unexpected behaviour

    - by capcom
    Please refer to the following code which continuously calls a new AsyncTask. The purpose of the AsyncTask is to make an HTTP request, and update the string result. package room.temperature; import java.io.BufferedReader; import java.io.InputStream; import java.io.InputStreamReader; import java.util.ArrayList; import java.util.concurrent.ExecutionException; import org.apache.http.HttpEntity; import org.apache.http.HttpResponse; import org.apache.http.NameValuePair; import org.apache.http.client.HttpClient; import org.apache.http.client.entity.UrlEncodedFormEntity; import org.apache.http.client.methods.HttpPost; import org.apache.http.impl.client.DefaultHttpClient; import android.app.Activity; import android.os.AsyncTask; import android.os.Bundle; import android.util.Log; import android.widget.TextView; public class RoomTemperatureActivity extends Activity { String result = null; StringBuilder sb=null; TextView TemperatureText, DateText; ArrayList<NameValuePair> nameValuePairs; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); TemperatureText = (TextView) findViewById(R.id.temperature); DateText = (TextView) findViewById(R.id.date); nameValuePairs = new ArrayList<NameValuePair>(); for (int i = 0; i < 10; i++) { RefreshValuesTask task = new RefreshValuesTask(); task.execute(""); } } // The definition of our task class private class RefreshValuesTask extends AsyncTask<String, Integer, String> { @Override protected void onPreExecute() { super.onPreExecute(); } @Override protected String doInBackground(String... params) { InputStream is = null; try { HttpClient httpclient = new DefaultHttpClient(); HttpPost httppost = new HttpPost("http://mywebsite.com/roomtemp/tempscript.php"); httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs)); HttpResponse response = httpclient.execute(httppost); HttpEntity entity = response.getEntity(); is = entity.getContent(); } catch(Exception e) { Log.e("log_tag", "Error in http connection" + e.toString()); } try { BufferedReader reader = new BufferedReader(new InputStreamReader(is,"iso-8859-1"),8); sb = new StringBuilder(); sb.append(reader.readLine()); is.close(); result=sb.toString(); } catch(Exception e) { Log.e("log_tag", "Error converting result " + e.toString()); } return result; } @Override protected void onProgressUpdate(Integer... values) { super.onProgressUpdate(values); } @Override protected void onPostExecute(String result) { super.onPostExecute(result); //System.out.println(result); setValues(result); } } public void setValues(String resultValue) { System.out.println(resultValue); String[] values = resultValue.split("&"); TemperatureText.setText(values[0]); DateText.setText(values[1]); } } The problem I am experiencing relates to the AsyncTask in some way or the function setValues(), but I am not sure how. Essentially, I want each call to the AsyncTask to run, eventually in an infinite while loop, and update the TextView fields as I have attempted in setValues. I have tried since yesterday after asking a question which led to this code, for reference. Oh yes, I did try using the AsyncTask get() method, but that didn't work either as I found out that it is actually a synchronous call, and renders the whole point of AsyncTask useless.

    Hi I have an application that calls the android phone's default camera to take photo the following is my code. Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); startActivityForResult(intent, TAKE_PICTURE); and in the onActivityResult method I am doing the following if ((requestCode == TAKE_PICTURE) && (resultCode == Activity.RESULT_OK)) { Uri photoPath = intent.getData(); // do something with the uri here } The above code works fine on htc Tatto and Sony ericsson's x10 running 1.6 but in on htc G1 running 1.6 the above code causes the following exception 03-08 18:54:25.906: ERROR/AndroidRuntime(4344): Uncaught handler: thread main exiting due to uncaught exception 03-08 18:54:25.966: ERROR/AndroidRuntime(4344): java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=1, result=-1, data=Intent { act=inline-data (has extras) }} to activity removed java.lang.NullPointerException 03-08 18:54:25.966: ERROR/AndroidRuntime(4344): at android.app.ActivityThread.deliverResults(ActivityThread.java:3224) 03-08 18:54:25.966: ERROR/AndroidRuntime(4344): at android.app.ActivityThread.handleSendResult(ActivityThread.java:3266) 03-08 18:54:25.966: ERROR/AndroidRuntime(4344): at android.app.ActivityThread.access$2600(ActivityThread.java:116) 03-08 18:54:25.966: ERROR/AndroidRuntime(4344): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1823) 03-08 18:54:25.966: ERROR/AndroidRuntime(4344): at android.os.Handler.dispatchMessage(Handler.java:99) 03-08 18:54:25.966: ERROR/AndroidRuntime(4344): at android.os.Looper.loop(Looper.java:123) 03-08 18:54:25.966: ERROR/AndroidRuntime(4344): at android.app.ActivityThread.main(ActivityThread.java:4203) 03-08 18:54:25.966: ERROR/AndroidRuntime(4344): at java.lang.reflect.Method.invokeNative(Native Method) 03-08 18:54:25.966: ERROR/AndroidRuntime(4344): at java.lang.reflect.Method.invoke(Method.java:521) 03-08 18:54:25.966: ERROR/AndroidRuntime(4344): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:791) 03-08 18:54:25.966: ERROR/AndroidRuntime(4344): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:549) 03-08 18:54:25.966: ERROR/AndroidRuntime(4344): at dalvik.system.NativeStart.main(Native Method) 03-08 18:54:25.966: ERROR/AndroidRuntime(4344): Caused by: java.lang.NullPointerException 03-08 18:54:25.966: ERROR/AndroidRuntime(4344): at removed 03-08 18:54:25.966: ERROR/AndroidRuntime(4344): at android.app.Activity.dispatchActivityResult(Activity.java:3624) 03-08 18:54:25.966: ERROR/AndroidRuntime(4344): at android.app.ActivityThread.deliverResults(ActivityThread.java:3220) 03-08 18:54:25.966: ERROR/AndroidRuntime(4344): ... 11 more Any insights into how to solve this problem.

  • HTTP 500 ERROR on CAS Server while setting SSLVerifyClent as "required"

    - by Huiyu.Bird
    I have 3 servers, a Apache Server, a JBOSS Server and a CAS Server for SSO. The Apache Server resolve all request with a domain such as www.request.com, and the path of CAS Server is www.request.com/cas, and JBOSS Server is www.request.com/jboss (This app got a CAS client). My problem is if I set SSLVerifyClient require for the NameVirtualHost of www.request.com in my Apache Server, I got a HTTP 500 error during the redirecting to the JBOSS Server(http://www.request.com/jboss), after logined in the CAS login page successfully. But everything goes successfully if there is no SSLVerifyClient require . Error logs of my Apache Server : [Mon Apr 19 17:07:25 2010] [error] Re-negotiation handshake failed: Not accepted by client!? Error logs of my JBOSS Server : 2010-04-19 17:29:57,263 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/jboss].[jsp]] (ajp-0.0.0.0-8009-1) Servlet.service() for servlet jsp threw exception org.jasig.cas.client.validation.TicketValidationException: The CAS server returned no response. at org.jasig.cas.client.validation.AbstractUrlBasedTicketValidator.validate(AbstractUrlBasedTicketValidator.java:162) at org.jasig.cas.client.validation.AbstractTicketValidationFilter.doFilter(AbstractTicketValidationFilter.java:129) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jasig.cas.client.authentication.AuthenticationFilter.doFilter(AuthenticationFilter.java:103) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jasig.cas.client.session.SingleSignOutFilter.doFilter(SingleSignOutFilter.java:78) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.springframework.web.filter.CharacterEncodingFilter.doFilterInternal(CharacterEncodingFilter.java:96) at org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:75) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.in Any tips will be highly appreciated.

  • Apache Camel ESB for C# and Java EDA

    - by Dokie
    Hi We are looking at integrating some of our coarse grained business Services using an Event Driven Architecture (EDA) and the server side of these Services (REST) are implemented in both Java and .NET (C#). We originally thought of using RabbitMQ (and AMQP protocol) as a neutral and open means (with good client support in these two languages), but it means having to support another runtime (Erlang) alongside Java and the CLR. We are also looking at Apache qPid as that has a Java broker implementation of the AMQP protocol which might eliminate that concern. Does anyone have any experience of trying to use the richer Apache Camel ESB on top of ActiveMQ to integrate Java and .NET Services in a Pub-Sub EDA manner? Have I missed any other possible suggestions as to a route through this? Thanks

  • Android SQLite database gets corrupted

    - by Seu
    There are about 100 people using my Android App right now and every once and while I get a crash report to the server with this stack trace: android.database.sqlite.SQLiteDatabaseCorruptException: database disk image is malformed at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2596) at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2621) at android.app.ActivityThread.access$2200(ActivityThread.java:126) at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1932) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:123) at android.app.ActivityThread.main(ActivityThread.java:4595) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:521) at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:860) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:618) at dalvik.system.NativeStart.main(Native Method) Caused by: android.database.sqlite.SQLiteDatabaseCorruptException: database disk image is malformed at android.database.sqlite.SQLiteQuery.native_fill_window(Native Method) at android.database.sqlite.SQLiteQuery.fillWindow(SQLiteQuery.java:75) at android.database.sqlite.SQLiteCursor.fillWindow(SQLiteCursor.java:295) at android.database.sqlite.SQLiteCursor.getCount(SQLiteCursor.java:276) at android.database.AbstractCursor.moveToPosition(AbstractCursor.java:171) at android.database.AbstractCursor.moveToFirst(AbstractCursor.java:248) The result is the app crashing and all the data in the DB being lost. One thing to note is that every time I read or write to the database I get a new SQLiteDatabase and close it as soon as I'm done. I thought this would simplify things, but perhaps that's causing the problem? Is it possible this is just a SQLite bug?

  • Anyone have BlazeDS working with WebLogic Security (j_security_check) ??

    - by Brian
    I'm working on a Flex implementation (currently using SDK 3.5) on WebLogic 10.3 (11G.) We originally used Glassfish v2.1.1 with zero issues (there was an active directory group lookup bug but it did not hinder our progress.) Since transitioning to WebLogic we have an issue where the flexsession is invalidated after logging in using j_security_check: [BlazeDS]Unexpected error encountered in Message Broker servlet flex.messaging.LocalizedException: The FlexSession is invalid. at flex.messaging.FlexSession.checkValid(FlexSession.java:943) at flex.messaging.FlexSession.getUserPrincipal(FlexSession.java:254) at flex.messaging.HttpFlexSession.getUserPrincipal(HttpFlexSession.java:286) at flex.messaging.MessageBrokerServlet.service(MessageBrokerServlet.java:296) at javax.servlet.http.HttpServlet.service(HttpServlet.java:820) at weblogic.servlet.internal.StubSecurityHelper$ServletServiceAction.run(StubSecurityHelper.java:227) at weblogic.servlet.internal.StubSecurityHelper.invokeServlet(StubSecurityHelper.java:125) at weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.java:292) at weblogic.servlet.internal.ServletStubImpl.execute(ServletStubImpl.java:175) at weblogic.servlet.internal.WebAppServletContext$ServletInvocationAction.run(WebAppServletContext.java:3594) at weblogic.security.acl.internal.AuthenticatedSubject.doAs(AuthenticatedSubject.java:321) at weblogic.security.service.SecurityManager.runAs(SecurityManager.java:121) at weblogic.servlet.internal.WebAppServletContext.securedExecute(WebAppServletContext.java:2202) at weblogic.servlet.internal.WebAppServletContext.execute(WebAppServletContext.java:2108) at weblogic.servlet.internal.ServletRequestImpl.run(ServletRequestImpl.java:1432) at weblogic.work.ExecuteThread.execute(ExecuteThread.java:201) at weblogic.work.ExecuteThread.run(ExecuteThread.java:173) I've tried almost every option in services-config.xml: [security [login-command class="flex.messaging.security.WeblogicLoginCommand" server="Weblogic"/> [!-- Uncomment the correct app server [login-command class="flex.messaging.security.TomcatLoginCommand" server="JBoss"> [login-command class="flex.messaging.security.JRunLoginCommand" server="JRun"/> [login-command class="flex.messaging.security.TomcatLoginCommand" server="Tomcat"/> [login-command class="flex.messaging.security.WebSphereLoginCommand" server="WebSphere"/> --> [/security> I've even completely removed this section with no luck. The login functions correctly from a non-BlazeDS perspective. It authenticates the user correctly. Without authentication, BlazeDS works fine (no errors for any remote calls.) Together its a big ball of fail (invalid flexsession every time.) Has anyone got this working? Any tips?
