  • getting IllegalAccessException when accessing a protected method from parent from inner class

    - by EnToutCas
    I got a very weird problem and a weird solution: class Parent { protected void aProtectedMethod() { doSomething(); } } class Child extends Parent { void anotherMethod() { new SomeInterface() { public void interfaceMethod() { aProtectedMethod(); } }; } } When child.anotherMethod() is run, I got IllegalAccessException at myProtectedMethod(), saying my inner class doesn't have access to the Parent class... However, if I add: protected void aProtectedMethod() { super.aProtectedMethod(); } in my Child class, everything is fine... I wonder why this is?

  • After HTTP GET request, the resulting string is cut-off (incomplete)

    - by Jayomat
    hi all, I'm making a http get request like this: try { HttpClient client = new DefaultHttpClient(); String getURL = "http://busspur02.aseag.de/bs.exe?SID=5FC39&ScreenX=1440&ScreenY=900&CMD=CR&Karten=true&DatumT="+day+"&DatumM="+month+"&DatumJ="+year+"&ZeitH="+hour+"&ZeitM="+min+"&Intervall=60&Suchen=(S)uchen&GT0=Aachen&T0=H&HT0="+start_from+"&GT1=Aachen&T0=H&HT1="+destination+""; HttpGet get = new HttpGet(getURL); HttpResponse responseGet = client.execute(get); HttpEntity resEntityGet = responseGet.getEntity(); if (resEntityGet != null) { //do something with the response Log.i("GET RESPONSE",EntityUtils.toString(resEntityGet)); } ........ It all works well... the only problem: the output from Log.i is cut-off... It's not the complete html page. If I make the same request in a browser, I get 3x the output in opposition to making the request in the emulator and using the above code.... what's wrong?

  • NullPointerException when adding to BigDecimal

    - by Dan
    String[] toppings = new String[10]; BigDecimal toppingsPrice = null; toppings[0] = req.getParameter("extraCheese"); toppings[1] = req.getParameter("moreTomatoes"); toppings[2] = req.getParameter("extraOnions"); // ... for(int i = 0; i < toppings.length; i++) { if(toppings[i] != null) { toppingsPrice.add(new BigDecimal("0.99")); // <-- NPE is caused here. toppingsPrice = toppingsPrice.setScale(2, BigDecimal.ROUND_HALF_EVEN); } } I am getting a NullPointerException in the above code when adding 0.99 to toppingsPrice. I am working with money values, so I have used BigDecimal. Is there something wrong with how I am adding the 0.99c price?

  • Why isn't this simple program working?

    - by user1445478
    I'm writing a very basic program that aims for the text view to display the phrase "Hello" after a button is pressed on the screen. However, I can't get this program to work; every time I run it, it says that the application has stopped unexpectedly. This is the program I wrote: public class EtudeActivityActivity extends Activity{ TextView tvResponse; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); final TextView tvResponse = (TextView) findViewById (R.id.tvResponse); } public void updateTV(View v) { tvResponse.setText("Hello"); } } Also, I inserted an android:onClick = "updateTV" into my main.xml file for the button. Thanks for any help!

  • JDBC Connection pool monitoring GlassFish

    - by john
    I am trying to find a setting by which the connection pool monitoring information would come in the server.log whenever an error like "error allocating a connection" or "connection closed" occur. I found some blog entries that talk about this but they mention it from GUI prespective. However, I want a setting on the connection pool itself so that perodically the connection pool monitoring information would be shown in the logs. Does anyone know of such a setting? On Sun app Server 8.X it used to be perf-monitor

  • User will input some filter criteria -- how can I turn it into a regular expression for String.match

    - by envinyater
    I have a program where the user will enter a string such as PropertyA = "abc_*" and I need to have the asterisk match any character. In my code, I'm grabbing the property value and replacing PropertyA with the actual value. For instance, it could be abc_123. I also pull out the equality symbol into a variable. It should be able to cover this type of criteria PropertyB = 'cba' PropertyC != '*-this' valueFromHeader is the lefthand side and value is the righthand side. if (equality.equals("=")) { result = valueFromHeader.matches(value); } else if (equality.equals("!=")) { result = !valueFromHeader.matches(value); } EDIT: The existing code had this type of replacement for regular expressions final String ESC = "\\$1"; final String NON_ALPHA = "([^A-Za-z0-9@])"; final String WILD = "*"; final String WILD_RE_TEMP = "@"; final String WILD_RE = ".*"; value = value.replace(WILD, WILD_RE_TEMP); value = value.replaceAll(NON_ALPHA,ESC); value = value.replace(WILD_RE_TEMP, WILD_RE); It doesn't like the underscore here... abcSite_123 != abcSite_123 (evaluates to true) abcSite_123$1.matches("abcSite$1123") It doesn't like the underscore...

  • Framework Recommendation request: spring, struts, j2ee?

    - by Jack BeNimble
    The last time I looked at web applications, the consensus seemed to be Struts/J2EE. Now, it looks like Spring MVC/J2EE or Struts/J2EE are both viable solutions. Is this generally correct? Or is Spring MVC now the consensus choice over Struts? We have at least one guy who has worked with Struts before and wants to go with that. I'm more familiar with Struts as well, having reviewed in the past. Also, is J2EE still considered the viable solution for handling remote components? Or are there alternatives?

  • When calling CRUD check if "parent" exists with read or join?

    - by Trick
    All my entities can not be deleted - only deactivated, so they don't appear in any read methods (SELECT ... WHERE active=TRUE). Now I have some 1:M tables on this entities on which all CRUD operations can be executed. What is more efficient or has better performance? My first solution: To add to all CRUD operations: UPDATE ... JOIN entity e ... WHERE e.active=TRUE My second solution: Before all CRUD operations check if entity is active: if (getEntity(someId) != null) { //do some CRUD } In getEntity there's just SELECT * FROM entity WHERE id=? AND active=TRUE. Or any other solution, recommendation,...?

  • Customizing jTable

    - by gmile
    I need to customize my jTable. All I need, is to put a custom Swing object (like jButon, jPanel, etc.) into the table cell. Is it possible? I'm trying: jTable.getModel.setValueAt(jPanel1,0,0) and jTable.getModel.setValueAt(jPanel1.getUI(),0,0) But the result is only a some kind of string, representing the object... Any ideas?

  • Eclipse: Should I create a workspace for each project ?

    - by Zombies
    I am simply wondering whether it is best to put all of my Eclipse projects into one workspace, or do a 1 workspace per 1 project. I am just a solo developer, for hobby more or less, but the apps I create do actually have production versions that are running on rather frequent cron jobs, so its almost like an amateur production environment. The only problems I have noticed so far is for exporting JARs, I have the potential to include source files from other projects which seems like it could get messy (maybe?).

  • Starting new transaction in Spring bean

    - by Marcus
    We have: @Transactional(propagation = Propagation.REQUIRED) public class MyClass implementes MyInterface { ... MyInterface has a single method: go(). When go() executes we start a new transaction which commits/rollbacks when the method is complete - this is fine. Now let's say in go() we call a private method in MyClass that has @Transactional(propagation = Propagation.REQUIRES_NEW. It seems that Spring "ignores" the REQUIRES_NEW annotation and does not start a new transaction. I believe this is because Spring AOP operates on the interface level (MyInterface) and does not intercept any calls to MyClass methods. Is this correct? Is there any way to start a new transaction within the go() transaction? Is the only way to call another Spring managed bean that has transactions configured as REQUIRES_NEW? Update: Adding that when clients execute go() they do so via a reference to the interface, not the class: @Autowired MyInterface impl; impl.go();

  • How to send exceptions to exceptionController?

    - by ivar
    <bean class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver"> <property name="mappedHandlers"> <set> <ref bean="exceptionController" /> </set> </property> <property name="defaultErrorView" value="tiles/content/error" /> </bean> I'm trying to send exceptions to a controller so I can create a redirect. If I comment out the mappedHandlers part then the error tile is displayed but it is only a tile. The rest of the tiles load normally. I need to make a redirect in the controller so I can show an error page not just an error tile. I can't find enough information or an example how the exception invokes some method in exceptionController.
