User Information: Cinema 4D Version: 8.100 Platform: Windows ; Language(s) :
--------- I am a newbie and learning basic Java programming. I have had a standard edition of SDK 1.4 on my system and JCreator on top of that. Up till now everything worked well. I do not know the difference between the JSE 1.4 and J2EE. I got my SDK off a file share utility than go to Java.sun website as it easier to make a choice. I guess I am too lazy to read all the technical stuff. The problem started with not being able to execute following error detection... The rest of the code worked but every time I tested for the following code I got a java lang error. Initially I thought I had syntax problem. But I noticed all my applications that worked previously were behaving the same way. if(response==null) { JOptionPane.showMessageDialog(null,"You clicked Cancell"); System.exit(0); } else if(response.equals("") { JOption.showMessageDialog(null,"You sent an empty string"); System.exit(0); } I eventually decided to reinstall the SDK and JCreator. But I had to decide whether to install JSE or J2EE. I downloaded both then reinstalled JCreator. This procedure normally worked and I did not need to set the path under enviornment variables. But I am finding that this does not work now. Non of my previous applications do not compile or run. I get following error: --------------------Configuration: Test - j2sdk1.4.1_02 <Default> - <Default>-------------------- Error : Invalid path, C:\j2sdk1.4.1_02\bin\javac.exe -classpath "D:\JavaFiles\Test\classes" -d D:\JavaFiles\Test\classes D:\JavaFiles\Test\src\Test.java" Process completed.

Just to let you know that I scrapped SDK 1.4 thinking it is a bug problem and reinstalled the older 1.3 version. Fortunately this time, when I installed JCreator it saw the SDK and compiled and ran most of my previous applications. However the originating problem exists. I keep getting NullPointerException error when try to run following file public static void main(String args[]) { String response; String moreBankingBusiness; moreBankingBusiness=JOptionPane.showInputDialog ("Do you want to do some banking?"); moreBankingBusiness=moreBankingBusiness.toUpperCase(); while(moreBankingBusiness.equals("YES")) { response=JOptionPane.showInputDialog ("***Select Banking Options***\n\n"+ "1 for deposit" + "\n"+"2 for withdrawal"+ "\n" +"3 for balance query"); if(response==null) { JOptionPane.showMessageDialog (null,"You clicked cancel"); System.exit(0); } }// end of while } // end of main }// end of class I suspect the text in blue is the offending code. I would be most grateful for a solution. Regards SS

What you are asking is completely out of scope of this forum, you will get much better replies from a Java specific message board.
