| | Because [URL="http://www.w3.org/TR/DOM-Level-2-HTML/html.html#ID-85676760"]selectedIndex [/URL]can't be a alphabet; it has to be numeric; more specifically long. It would be better if you just passed in `this' and got the value selected using:[code] function showSomething(elem) { var val = elem.options[elem.selectedIndex].value; // process the value } // in your markup <select id="choice" onchange="showReg(this);" size="4"> … |

| | The warnings are because the specification uses all lowercase convention when specifying intrinsic event handlers; i.e. onchange in favor of onChange. Since this is some library specific issue, your best bet is to run this application in Firefox and use the Firefox Error console or the addon Firebug to trace … |
| | If your project was set up in Eclipse, the "[URL="http://www.java-tips.org/other-api-tips/eclipse/how-to-restore-deleted-files-in-eclipse.html"]Restore from Local History[/URL]" option might work out for you; it's worth a try. |

| | Indeed; the entire point of the exercise was to make use of basic math tricks to come up with a compact solution and to exercise the basics of OOP. Create a class which bears the responsibility of accepting a number and maintaining the state of which range appears how many … |
| | > although I have this "izraz.txt" file in the correct location If that were the case, the said exception won't be thrown by the Java runtime. The solution to this issue depends on how you are executing your program. Are you using an IDE, or is it a command line … |
| | Simply put, the list returned by the `findFlights' method seems to return a list of Object arrays rather than a list of FlightItenary. Don't mix and match type safe code with non-type safe code; either use generics all the way through or don't use it at all [not recommended]. Try … |
| | > I want to prevent visitors from being able to type anything in this > field altogether This isn't a JSP question but relates more to the markup language used; I guess HTML here.

| | How about getting started by doing a bit of simple PHP/Javascript coding, coming across real problems and then asking for help? |
| | Just to get the terminology right, a string is just a sequence of unicode characters, there is nothing `binary' in it. In the end, everything is stored as a byte, the way the byte sequence is interpreted is what makes all the difference. If your intention here is to grab … |

| | The twoDArray in your case is just an array of size 10 with each slot referring to a integer array i.e. two dimensional arrays in Java are just an array of arrays. Hence you can either use [icode]twoDArray[3] = oneDArray;[/icode] or [icode]System.arraycopy[/icode] if you don't want modifications in the original … |
| | Saying that 'XXX is not possible in Java' is pretty misleading IMO. Is I/O and Networking possible in Java? You might say yes, there are packages like [ICODE]java.io.*[/ICODE] and [ICODE]java.net.*[/ICODE] for it. But is it really possible in *java*? Both I/O and Networking libraries which are part of the standard … |
 | From what I understand, your web page has a text field which allows the user to enter his search criteria. Based on the user input, a new set of check boxes are fetched from the server but before doing that, you need to persist the state of the check boxes … |

| | It's pretty easy; make full use of the conditional expression which gets tested before the body of the loop is executed. When the given condition is reached or encountered within the loop body, set a boolean flag and test the same in your loop conditional.[code] for(int i = 0; i … |

 | Re: Context problem The value of `this' depends on the context in which the function was invoked and hence can only be known at runtime. Hence saying that "here `this' refers to XXX" holds little truth since I can very well have a object with its property set to func.a in which case … |
| | You need to mark the field of type [ICODE]MessageContext [/ICODE] as [ICODE]transient [/ICODE]so that the serialization mechanism doesn't attempt to serialize it. This only works if the state of the [ICODE]MessageContext [/ICODE]has no significance whatsoever to the newly reconstituted [ICODE]SoapPair [/ICODE]object. If it does, then you have to manually write … |

| | In the code posted I don't see the stream/writer being closed. Variable names like cloudOut1 through cloudOut11 suggest there is something seriously wrong with your design. Try writing out a small and compilable test case which illustrates the problem at hand at post it here. |

| | Proper encoding headers need to be set when requesting and serving the resource e.g. Content-Type and Content-Encoding. Just having utf-8 charset doesn't mean the content is not encoded in some other encoding. Inspect the requested .js file in a unicode aware text editor and see if it really is unicode … |
| | Re: Recursion help > Every call cause store whole array on the stack. No it doesn't. Arrays in Java are objects and when invoking methods with object references, copy of the reference is created and copied to the stack frame which is then pushed onto the call stack [the stack which maintains the … |
 | > I can't figure out how to write to a specific line of a text file. An efficient way would be to open the file using a [URL="http://java.sun.com/j2se/1.5.0/docs/api/java/io/RandomAccessFile.html"]RandomAccessFile [/URL]in read/write mode though things can get pretty nasty if care is not exercised. Almost all other methods include reading a line … |
