  • What is the best IDE?

    - by venom
    Hello. As a not so experienced man in programming, I start to use netbeans PLATFORM. And I am really impressed by its power (for rich desktop app). I have been learning the programming in another way on university. I have never thought that something as powerful as nb Platform exists. My idea was that 30 people work on some rich desktop app for more than year to make it "beta". Now I know, that it is much more easier. But, I have never be satisfied with my own opinions about "something is best". I am still looking for better mouse trap. So the question is: What is most powerful IDE you know? (it does not strongly depends on language, it means if some combination of language/IDE is really powerful, feel free to answer.)

  • Why isn't my bundle getting passed?

    I'm trying to pass a bundle of two values from a started class to my landnav app, but according to the debug nothing is getting passed, does anyone have any ideas why? package edu.elon.cs.mobile; import android.app.Activity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.EditText; public class PointEntry extends Activity{ private Button calc; private EditText longi; private EditText lati; private double longid; private double latd; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.pointentry); calc = (Button) findViewById(R.id.coorCalcButton); calc.setOnClickListener(landNavButtonListener); longi = (EditText) findViewById(R.id.longitudeedit); lati = (EditText) findViewById(R.id.latitudeedit); } private void startLandNav() { Intent intent = new Intent(this, LandNav.class); startActivityForResult(intent, 0); } private OnClickListener landNavButtonListener = new OnClickListener() { @Override public void onClick(View arg0) { Bundle bundle = new Bundle(); bundle.putDouble("longKey", longid); bundle.putDouble("latKey", latd); longid = Double.parseDouble(longi.getText().toString()); latd = Double.parseDouble(lati.getText().toString()); startLandNav(); } }; } This is the class that is suppose to take the second point package edu.elon.cs.mobile; import com.google.android.maps.GeoPoint; import com.google.android.maps.MapActivity; import com.google.android.maps.MapController; import com.google.android.maps.MapView; import com.google.android.maps.MyLocationOverlay; import com.google.android.maps.Overlay; import android.content.Context; import android.graphics.drawable.Drawable; import android.hardware.Sensor; import android.hardware.SensorEvent; import android.hardware.SensorEventListener; import android.hardware.SensorManager; import android.location.Location; import android.location.LocationManager; import android.os.Bundle; import android.util.Log; import android.widget.EditText; import android.widget.TextView; public class LandNav extends MapActivity{ private MapView map; private MapController mc; private GeoPoint myPos; private SensorManager sensorMgr; private TextView azimuthView; private double longitudeFinal; private double latitudeFinal; double startTime; double newTime; double elapseTime; private MyLocationOverlay me; private Drawable marker; private GeoPoint finalPos; private SitesOverlay myOverlays; public LandNav(){ startTime = System.currentTimeMillis(); } public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.landnav); Bundle bundle = this.getIntent().getExtras(); if(bundle != null){ longitudeFinal = bundle.getDouble("longKey"); latitudeFinal = bundle.getDouble("latKey"); } azimuthView = (TextView) findViewById(R.id.azimuthView); map = (MapView) findViewById(R.id.map); mc = map.getController(); sensorMgr = (SensorManager) getSystemService(Context.SENSOR_SERVICE); LocationManager lm = (LocationManager)getSystemService(Context.LOCATION_SERVICE); Location location = lm.getLastKnownLocation(LocationManager.GPS_PROVIDER); int longitude = (int)(location.getLongitude() * 1E6); int latitude = (int)(location.getLatitude() * 1E6); finalPos = new GeoPoint((int)(latitudeFinal*1E6), (int)(longitudeFinal*1E6)); myPos = new GeoPoint(latitude, longitude); map.setSatellite(true); map.setBuiltInZoomControls(true); mc.setZoom(16); mc.setCenter(myPos); marker = getResources().getDrawable(R.drawable.greenmarker); marker.setBounds(0,0, marker.getIntrinsicWidth(), marker.getIntrinsicHeight()); me = new MyLocationOverlay(this, map); myOverlays = new SitesOverlay(marker, myPos, finalPos); map.getOverlays().add(myOverlays); } @Override protected boolean isRouteDisplayed() { return false; } @Override protected void onResume() { super.onResume(); sensorMgr.registerListener(sensorListener, sensorMgr.getDefaultSensor(Sensor.TYPE_ORIENTATION), SensorManager.SENSOR_DELAY_UI); me.enableCompass(); me.enableMyLocation(); //me.onLocationChanged(location) } protected void onPause(){ super.onPause(); me.disableCompass(); me.disableMyLocation(); } @Override protected void onStop() { super.onStop(); sensorMgr.unregisterListener(sensorListener); } private SensorEventListener sensorListener = new SensorEventListener() { @Override public void onAccuracyChanged(Sensor arg0, int arg1) { // TODO Auto-generated method stub } private boolean reset = true; @Override public void onSensorChanged(SensorEvent event) { newTime = System.currentTimeMillis(); elapseTime = newTime - startTime; if (event.sensor.getType() == Sensor.TYPE_ORIENTATION && elapseTime > 400) { azimuthView.setText(Integer.toString((int) event.values[0])); startTime = newTime; } } }; }

  • Freemarker template not found

    - by brock
    Hi, I'm currently trying to get Freemarker to work with my application using Spring. No matter what I try I keep getting template not found. I am not sure if I have the configuration set up properly, but it never finds my template. Here is my spring bean config: <bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer"> <property name="templateLoaderPath" value="/WEB-INF/freemarker/"/> </bean> Whenever I try to call getTemplate on the freemaker configuration it always sends back a template not found error. So if I do configuration.getTemplate("testTemplate.ftl") it always throws an IOException. I'm not sure if anyone has an idea of what I'm doing wrong. Thanks for all your help!

  • JLabel with separate text and icon background colours

    - by emeraldjava
    Hey, I have a simple Jlabel element with text and icon setting the background changes the full label colour. I want to be able to only render the background colour on the text section of the label, ie - to have separate backgrounds/foregrounds for the icon and text. Selecting/deselecting the label will flip the colour behind the icon and text. Is this possible to do this by just extending JLabel, and if so which methods should i be looking to customise? My alternative idea is to create a panel with two separate label elements, one with an icon the other with text. It seems a bit messy, and before i start i'm wondering is there a smarter way of achieving this with Swing.

  • Reflection: cast an object to subclass without use instaceof

    - by Fabrizio
    I have this simple interface/class: public abstract class Message { } public class Message1 extends Message{ } public class Message2 extends Message{ } And an utility class: public class Utility { public void handler(Message m){ System.out.println("Interface: Message"); } public void handler(Message1 m){ System.out.println("Class: Message1"); } public void handler(Message2 m){ System.out.println("Class: Message2"); } } Now, the main class: public static void main(String[] args) { Utility p=new Utility(); Message1 m1=new Message1(); p.handler(m1); Message m=(Message) m1; p.handler(m); } The output is Class: Message1 Interface: Message I would that p.handler(m) call the method p.handler(m:Message1) I don't want use the "manual" command instanceof because I have many cases: if(m instance of Message1) p.handler((Message1)m) else if (m instanceof Message2) p.handler((Message2)m) ... If I call m.getClass() I obtain "mypackage.Message1", so the subclass and not the superclass. I try with this code (use reflection): p.handler(m.getClass().cast(m)); But the output is Interface: Message So, this is my problem. I would do a runtime cast of superclass object to subclassobject without use the "code command" istanceof. I would a right command like this: p.handler((m.getclass)m); How can I obtain it? It's possible? Thank in advance. Fabrizio

  • How to change webservice url endpoint ?

    - by EugeneP
    I generated a web-service client using JBoss utils (JAX-WS compatible) using Eclipse 'web service client from a wsdl'. So, the only thing I provided was a url to a web-service. Now, the web service provider tells me to change the "client endpoint" of the web-service. What is it and how to change it?

  • Can I use two different look and feels in the same Swing application?

    - by DR
    I'm using the Flamingo ribbon and the Substance Office 2007 look and feel. Of course now every control has this look and feel, even those on dialog boxes. What I want is something like in Office 2007, where the ribbons have their Office 2007 look, but other controls keep their native Vista/XP look. Is it possible to assign certain controls a different look and feel? Perhaps using some kind of chaining or a proxy look and feel?

  • Eager/Lazy loaded member always empty with JPA one-to-many relationship

    - by Kaleb Pederson
    I have two entities, a User and Role with a one-to-many relationship from user to role. Here's what the tables look like: mysql> select * from User; +----+-------+----------+ | id | name | password | +----+-------+----------+ | 1 | admin | admin | +----+-------+----------+ 1 row in set (0.00 sec) mysql> select * from Role; +----+----------------------+---------------+----------------+ | id | description | name | summary | +----+----------------------+---------------+----------------+ | 1 | administrator's role | administrator | Administration | | 2 | editor's role | editor | Editing | +----+----------------------+---------------+----------------+ 2 rows in set (0.00 sec) And here's the join table that was created: mysql> select * from User_Role; +---------+----------+ | User_id | roles_id | +---------+----------+ | 1 | 1 | | 1 | 2 | +---------+----------+ 2 rows in set (0.00 sec) And here's the subset of orm.xml that defines the tables and relationships: <entity class="User" name="User"> <table name="User" /> <attributes> <id name="id"> <generated-value strategy="AUTO" /> </id> <basic name="name"> <column name="name" length="100" unique="true" nullable="false"/> </basic> <basic name="password"> <column length="255" nullable="false" /> </basic> <one-to-many name="roles" fetch="EAGER" target-entity="Role" /> </attributes> </entity> <entity class="Role" name="Role"> <table name="Role" /> <attributes> <id name="id"> <generated-value strategy="AUTO"/> </id> <basic name="name"> <column name="name" length="40" unique="true" nullable="false"/> </basic> <basic name="summary"> <column name="summary" length="100" nullable="false"/> </basic> <basic name="description"> <column name="description" length="255"/> </basic> </attributes> </entity> Yet, despite that, when I retrieve the admin user, I get back an empty collection. I'm using Hibernate as my JPA provider and it shows the following debug SQL: select user0_.id as id8_, user0_.name as name8_, user0_.password as password8_ from User user0_ where user0_.name=? limit ? When the one-to-many mapping is lazy loaded, that's the only query that's made. This correctly retrieves the one admin user. I changed the relationship to use eager loading and then the following query is made in addition to the above: select roles0_.User_id as User1_1_, roles0_.roles_id as roles2_1_, role1_.id as id9_0_, role1_.description as descript2_9_0_, role1_.name as name9_0_, role1_.summary as summary9_0_ from User_Role roles0_ left outer join Role role1_ on roles0_.roles_id=role1_.id where roles0_.User_id=? Which results in the following results: +----------+-----------+--------+----------------------+---------------+----------------+ | User1_1_ | roles2_1_ | id9_0_ | descript2_9_0_ | name9_0_ | summary9_0_ | +----------+-----------+--------+----------------------+---------------+----------------+ | 1 | 1 | 1 | administrator's role | administrator | Administration | | 1 | 2 | 2 | editor's role | editor | Editing | +----------+-----------+--------+----------------------+---------------+----------------+ 2 rows in set (0.00 sec) Hibernate obviously knows about the roles, yet getRoles() still returns an empty collection. Hibernate also recognized the relationship sufficiently to put the data in the first place. What problems can cause these symptoms?

  • Why are error pages ignored in RESTEasy web service running on Tomcat?

    - by Chandru
    I'm developing a REST-ful web service using RESTEasy deployed on Tomcat. I've configured an error page which takes the exception's message and generates an XML based on it when any exception occurs during the request. This works fine for any application generated exceptions. However, if client sends an invalid XML which cannot be unmarshalled correctly, an javax.xml.bind.UnmarshalException is thrown and Tomcat's default error page is used instead of mine. I have configured my error page to the error-code 500 in web.xml. Is using error pages the correct way to handle errors when using RESTEasy or is there an alternative way?

  • Speed up compilation with mockito on Android

    - by pbreault
    I am currently developing an android app in eclipse using: One project for the app One project for the tests (Instrumentation and Pojo tests) In the test project, I am importing the mockito library for standard POJO testing. However, when I import the library, the compilation time skyrockets from 1 second to about 30 seconds in eclipse. The cause seems to be that the whole library is converted each time. So basically, each time a make a modification that I want to test, I have to wait 30 seconds. The only workarounds that I have found so far would be: Disable "Build Automatically" Create a project that includes only pojo tests and put mockito only there. Use another library that compiles faster (e.g. easymock) Any other suggestion?

  • Seam - list all components

    - by Walter White
    Hi all, I would like to get a list of all the components so that I can further process them. Is this possible, if so, how can I do that? I don't believe I can observe all postCreate events since it is simply an exact match and not a regular expression. @Observer("org.jboss.seam.postCreate.") You can only observe those events and not * as it is put into a map where the key is a string. Any ideas? Walter

  • Is it normal that conversationId keeps increasing after each page request?

    - by Casper
    Hi I'm building a Seam application and have a question: I got a stateless session bean (default seam scope) with a delete and a select method. A page which contains a datamodel loads and got links to select and delete each row (both links refer to the actionmethods in the bean). The delete method deletes the selected row from the list and returns null (reloads page). The select method loads a new page where the selected row can be edited. Each time a link in the datamodel is clicked and an action gets fired, the conversationId gets increased. Is this normal behaviour since im not even in a conversation? If it ain't normal behaviour, what's best practice to prevent this from happening?

What I am aiming for is overwriting this method so I can perform some actions before the sms/mail gets sent, then just allow it to perform its normal actions.

  • Spring integration with RabbitMQ

    We have build a solution based on file based delivery using Spring-Integration. This works fine but we need to process many files. We are happy with Spring Integration but we want to scale up. For this we'd like to use a messaging system like Rabbit MQ(or other solutions). Does anybody have experience with this, what's needed to get this working?

    Hello, I have a Map, which I tried to iterate over with JSTL. Somehow I could not accomplish even this basic task. I also referred the questions here and here, but that is what I am already doing, still no success. What I tried to do was: <c:forEach items="${myMap}" var="myEntry"> ${myEntry.key} + ${myEntry.value} </c:forEach> But I always get the last object. Maybe I am missing something trivial, please advise. Thank You

  • thread reaches end but isn't removed

    - by pstanton
    I create a bunch of threads to do some processing: new Thread("upd-" + id){ @Override public void run(){ try{ doSomething(); } catch (Throwable e){ LOG.error("error", e); } finally{ LOG.debug("thread death"); } } }.start(); I know i should be using a threadPool but i need to understand the following problem before i change it: I'm using eclipse's debugger and looking at the threads in the debug pane which lists active threads. Many of them complete as you would expect, and are removed from the debug pane, however some seem to stay in the list of active threads even though the log shows the "thread death" entry for these. When i attempt to debug these threads, they either do not pause for debugging or show an error dialog: "A timeout occurred while retrieving stack frames for thread: upd-...". there is some synchronization going on within the doSomething() call but i'm fairly sure it's ok and since the "thread death" log is being called i'm assuming these threads aren't deadlocked in that method. i don't do any Thread.join()s, however i do call a third party API but doubt they do either. Can anyone think of another reason these threads are lingering? Thanks. EDIT: I created this test to check the Garbage Collection theory: Thread thread = new Thread("!!!!!!!!!!!!!!!!") { @Override public void run() { System.out.println("running"); ThreadUs.sleepQuiet(5000); System.out.println("finished"); // <-- thread removed from list here } }; thread.start(); ThreadUs.sleepQuiet(10000); System.out.println(thread.isAlive()); // <-- thread already removed from list but hasn't been GC'd ThreadUs.sleepQuiet(10000); this proves that it is nothing to do with garbage collection as eclipse removes the thread from the thread list as soon as it completes and isn't waiting for the object to be de-referenced/GC'd.

  • Eclipse RCP: Actions vs Commands - would like an update

    - by nEm
    I know this question has been asked before but it was in 2009 and I haven't found anything more recent either on the web. I was wondering if the answer in that still holds or can it be updated? I am just starting work on an RCP and I haven't been able to decide between actions and commands for my menu items. I will be using a lot of the ones provided by Eclipse such as the Edit, File and some of their sub menu items as well. Since it has been nearly two years for the answer provided in the '09 question, I just wanted to make sure there is nothing else that could sway my decision in either direction or maybe if there have been some new developments that I am not aware of.
