When I tried to open the client i.e User interface which is MainMenuApp received NO_PERMISSION CORBA exception while attempting to get an initial reference to the mvcf_ControllerFactory from the FactoryFinder. Software defect that should be addressed is that the UI did not recover after catching the exception and required a restart of the UI to connect. The problem is that cleanWorkspace() in CorbaAdapter doesn't have any failover logic in it at all. The adapter is assumed to be good and if it is not cleanWorkspace() attempts to use a factory that doesn't exist. This throws an uncaught NullPointerException that blows out to MainMenuApp where it is interpreted as a fatal exception and prevents the main menu from starting. So please help me in writing the failover logic in CorbaAdapter The code for cleanWorkspace is /** * Cleans up the entire logical positions workspace. * @throws AdapterException UserError or Error occured */ public synchronized void cleanWorkspace() throws AdapterException { cut_ContextInitData cid = getContextInitData(); cid.clientId = "*"; MVC2CleanWorkspaceCmd cmd = new MVC2CleanWorkspaceCmd(cid); execute(cmd); }

I am trying to complete my last program for intro to Java. Can anyone explain how to create a new string from an old one and take out the spaces from that string?

The code is as follows. import java.awt.*; import java.awt.event.*; public class buttons1 extends Frame implements ActionListener { TextField t1; Button b1,b2,b3; Button[] bu; Button[] bt; Button BB; int x1=700; int y1=0; int x2=100; int y2=10; int x3=180; int y3=10; int s1; int s3; String s; public buttons1() { setLayout(null); t1=new TextField(20); b1=new Button("Enter"); add(b1); add(t1); b1.addActionListener(this); b1.setBackground(Color.blue); t1.setBounds(400,100,70,30); b1.setBounds(400,300,70,30); } public void actionPerformed(ActionEvent ae) { if(ae.getSource()==b1) { s=t1.getText(); s1=Integer.parseInt(s); System.out.println("Value of I is"+s1); String s2[]={"Rone","Rtwo","Rthree","Rfour","Rfive","Rsix","Rseven","Reight","Rnine","Rten","Releven","Rtwelve","Rthirteen","Rfourteen","Rfifteen"}; for(int i=0;i

If anyone could let me know how to get my intersection and difference methods to print properly. I have to use iterative loops and methods to complete this assignment so NO in built methods are to be used!Thanks [CODE] import java.util.Scanner; public class setPractice { public static Scanner kbd; public static final int MAXSIZE = 20; public static void main(String[] args) { kbd = new Scanner(System.in); int[] setA = new int[MAXSIZE]; int[] setB = new int[MAXSIZE]; int[] intersect = new int[MAXSIZE]; int[] difference = new int[MAXSIZE]; int sizeA, sizeB, interSize, diffSize; System.out.print("How many numbers will be in the 1st set: "); sizeA = kbd.nextInt(); while (sizeA > MAXSIZE) { System.out .print("Error: Set size is too large. Re-enter set size: "); sizeA = kbd.nextInt(); } System.out.println("Enter list of integers for 1st set: "); getData(setA, sizeA); sort(setA, sizeA); System.out.println("The ascending order for 1st is:"); print(setA, sizeA); System.out.print("How many numbers will be in the 2nd set: "); sizeB = kbd.nextInt(); while (sizeB > MAXSIZE) { System.out .print("Error: Set size is too large.

how to check given two number without using operators in java

I created a derby database backed swing application. I then wanted to archive the database for distribution with the application, the final goal being a single jar. Pre-archive queries that ran in no time now take 5 or so seconds. The application, which used to load in under a second, now takes nearly a minute to start up. My question is, will all archived databases run this much slower, or have I done something wrong? For what its worth, the database is 8.7 MB pre-archive, 2.1 MB as a jar, and the queries are not very complex.
