The overhead of starting the Java process and creating a VM is way too large in this test.

However, most companies are willing to negotiate a bit since the cost of replacing you (recruiting, hiring, training, etc.) is significant. In the US, unless you're part of a union you're usually under what's called "at will" employment, which means either party can terminate the agreement at any time, with or without cause, except for a few cases (e.g. discrimination, harrassment) specified by law.

In fact many boss, would encourage this type of work and I know of some that have heard of someone needing a consultant and they point an employee to that company - for a side job. - - - and they know that some of their programmers and engineers are doing small side jobs for different companies. I would not be running around shouting or bragging about any side work but I would not make it a secret or hide it. That just raises a lot of questions. I have even seen companies allow - the employee to use company equipment for this type of work. as it makes the employee happy. As long as it is after hours work and does not effect company work.

Thanks. It works! I take back everything I said about the feature not being there. The feature significantly reduces my need for an additional visual indicaton of whether variables and methods are instance, static or local. It also improves Eclipse's syntax colouring no end. Though - apparently inexplicably - it /still/ can't tell the difference between a numeric constant, a type name and a package name.

If a developer sends a struct memory image and then carefully documents what happens on the wire, byte by byte, then the fact that the origin is a memory image is irrelevant. If the memory image contains garbage passing then the final protocol definition will contain "undefined/unused" bytes. But the final definition MUST be a definition of what bytes go across the wire, and in what order. For this reason, any language capable of constructing and analysing a byte sequence is capable of conversing over IP sockets.

"ISO8859-1" ? I don't think it's a problem with javac, but rather a problem with the console to which you are outputting at runtime. I know that the windows CMD prompt does not display UNICODE correctly for me, and one way you can get around this is to instead log to a file using a FileWriter and then open up the file in a text editor or log viewer that supports the charset you are using to output. The FileWriter assumes a default character encoding which you can override when running the program by saying: % java -Dfile.encoding="ISO8859-1" language If you cannot change the way in which the class is invoked, you can create an OutputStreamWriter on a FileWriter and specify the character set.

Just found out that Java 1.5 actually includes a solution to this problem as well. Use the java.util.Scanner class, which includes methods to search various kinds of streams. InputStream stream = ...; Scanner scanner = new Scanner(stream); Pattern pattern = Pattern.compile(search); String match; while ((match = scanner.findWithinHorizon(pattern, 0)) != null) System.out.println(match); ============================================================================== TOPIC: Dynamic Data Exchange in java to link to windows application http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/8d2ffb69843ba63b ============================================================================== == 1 of 1 == Date: Tues, Dec 7 2004 11:31 am From: "AMI" Hi, I'm trying to use DDE (Dynamic Data Exchange) to establish a link with some Windows program using JAVA code. I use Classes provided by NEVA: http://www.nevaobject.com/_docs/_javadde/JavaDde.pdf . I'm using j2SE and eclipse IDE. Basically, the example that was provided in the documentation with the library was accessing an excel sheet , I checked it and it works fine. But when I try to connect to the application that I want to link to, it gives a windows error and terminates and my code gives an error "Execution failure: DdeConnect doesn't return (see MS Q136218)" Well, I checked for this error and the soln that I found was to add a message loop to the thread that created the window, I donnu what does this mean or how I can do it. So would someone help me with this? Thanks, Iman. This is the bug description as I found:: SYMPTOMS A 32-bit application calls DdeConnect when all previous DDEML initialization has been performed. DdeConnect never returns. CAUSE Any thread that creates a top-level window and doesn't have a message loop will cause DdeConnect to block. This is because DdeConnect calls SendMessage(HWND_BROADCAST...). In this call, SendMessage will put the message in the target thread's message queue and block the calling thread. If the target thread doesn't have a message loop, it will never process this message and therefore never return. One complication is that some things create windows without the knowledge of the calling thread. It is known that some SQL, RPC, and DDEML function calls will do this. Any top-level window that is created by a thread that has no message loop will cause this to happen. RESOLUTION The only current solution is to add a message loop to the thread that created the window. ============================================================================== TOPIC: Delete a panel inside a panel (2) http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/39f13ffc05d5cc4 ============================================================================== == 1 of 1 == Date: Wed, Dec 8 2004 8:49 am From: "HS1" Hello After got a help, I can delete a sub-panel inside a main-panel (a container with VerticalFlowLayout) for a delete button ( the button inside a sub-panel) by using: JPanel mainPanel = (JPanel)this.getParent(); mainPanel.remove(this); // "this" is the sub-panel mainPanel.repaint(); However, when I use this code, the sub panel is deleted but the main panel did not change. For example I have three sub-panels (top, centre, bottom). When I delete the centre sub-panel, this sub-panel is deleted but the top and bottom still in the same place. What I want is that the bottom sub-panel will move up. Do I have to remove all sub-panels then add them again or there is a better way to do that??? Could you please help Thank you SH1 ============================================================================== TOPIC: Where to place configuration files when using WAR-Files http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/74dc1db3e419defd ============================================================================== == 1 of 1 == Date: Tues, Dec 7 2004 8:04 pm From: Juha Laiho "Stephan Koser" <[EMAIL PROTECTED]> said: >we'd like to provide our web application as a WAR-File.

Perhaps even let go of the actual configuration file altogether, and move the individual variables into entries in the JNDI naming hierarchy. Or then just pass the conf.file name as a JNDI resource.
