  • Tool which can do both UML and ER Diagram

    - by Abhishek
    Hello, I have approval to buy one tool which can help programmers of my team to write better code. Most of my team members either do UML (.NET developers) or they do ER (database developers) Can you please recommend a tool for me which can do both of these type of diagrams? Please don't recommend Visio because my team already evaluated it and everyone disliked it as either a UML or ER diagram tool.

  • How to open AsyncTask from a Thread

    - by Abhishek
    In my application I have created a SplashScreen that will b shown for 5 Seconds and after that it executes an if else case depending upon the values stored in the Preference file. If Preference file contains values then the AsyncTask code will run else the Login form will load. When i try to run my application. The thread is going to the Login form with the help of intent but when it comes to AsyncTask my application shows a force close error message. This is my SplashScreen code: public class SplashScreen extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.splashscreen); Thread timer = new Thread() { public void run() { try { sleep(5000); } catch(InterruptedException e) { e.printStackTrace(); } finally { if(GoGolfPref.getEmail(SplashScreen.this)!=null && GoGolfPref.getPass(SplashScreen.this)!=null) { new LoadingScreen(SplashScreen.this, SplashScreen.this).execute("login_page", Login.url+GoGolfPref.getEmail(SplashScreen.this)+"/"+GoGolfPref.getPass(SplashScreen.this)); } else { Intent in = new Intent(SplashScreen.this, Login.class); startActivity(in); finish(); } } } }; timer.start(); } } This is the error I am getting: 08-29 07:25:58.040: E/AndroidRuntime(2365): FATAL EXCEPTION: Thread-10 08-29 07:25:58.040: E/AndroidRuntime(2365): java.lang.RuntimeException: Can't create handler inside thread that has not called Looper.prepare() 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.os.Handler.<init>(Handler.java:121) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.Dialog.<init>(Dialog.java:101) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.AlertDialog.<init>(AlertDialog.java:63) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.ProgressDialog.<init>(ProgressDialog.java:80) 08-29 07:25:58.040: E/AndroidRuntime(2365): at android.app.ProgressDialog.<init>(ProgressDialog.java:76) 08-29 07:25:58.040: E/AndroidRuntime(2365): at com.pnf.gogolf.LoadingScreen.<init>(LoadingScreen.java:130) 08-29 07:25:58.040: E/AndroidRuntime(2365): at com.pnf.gogolf.SplashScreen$1.run(SplashScreen.java:32) How to get this working?

    - by abhishek
    Hi, I have 3 drop-downs. 1st drop-down contains some values when the page loads. I need to populate 2 nd drop-down based on the value selected in 1st dropdown. Similarly, I need to populate 3 nd drop-down based on the value selected in 1st and 2nd dropdown. Initially I tried like this. <h:selectOneMenu value="#{stu.country}" > <f:selectItems value="#{bean.allCountries}" /> <a4j:support event="onchange" action="#{bean.retrieveStates(stu.country)}" reRender="states_dropDown"></a4j:support> </h:selectOneMenu> //ly, for 2nd drop-down <h:selectOneMenu id="states_dropDown" value="#{stu.state}" > <f:selectItems value="#{bean.allStates}" /> <a4j:support event="onchange" action="#{bean.retrieveCities(stu.country,stu.state)}" reRender="City_dropDown"></a4j:support> </h:selectOneMenu> Some times this code works fine. But some times it doesn't invoke managed bean method. Can you please help??

  • Why does Java not have any destructor like C++?

    - by Abhishek Jain
    Java has its own garbage collection implementation so it does not require any destructor like C++ . This makes Java developer lazy in implementing memory management. And Garbage Collection is very expensive. Still we can have destructor along with garbage collector where developer can free resources and which can save garbage collector's work. This might improves the performance of application. Why does Java not provide any destructor kind of mechanism? Developer does not have control over GC but he/she can control or create object. Then why not give them ability to destruct the objects?
