  • AS3 / Java - Socket Connection from live Flash to local java

    - by PitchBlackCat
    Hey guys, I'm trying to get a live flash that lives on a webserver to talk to a local java server, that will live on the clients PC. I'm trying to achieve this with a socket connection. (port 6000) Now, at first flash was able to connect, but it just sends <policy-file-request/>. After this nothing happens. Now, some people at Kirupa suggested to send an cross-domain-policy xml as soon as any connection is established from the java side. http://www.kirupa.com/forum/showthread.php?t=301625 However, my java server just throws the following: End Exception: java.net.SocketException: Software caused connection abort: recv failed I've already spend a great amount of time on this subject, and was wondering if anyone here knows what to do?

  • Batch file to uninstall all Sun Java versions?

    - by Ricket
    I'm setting up a system to keep Java in our office up to date. Everyone has all different versions of Java, many of them old and insecure, and some dating back as far as 1.4. I have a System Center Essentials server which can push out and silently run a .msi file, and I've already tested that it can install the latest Java. But old versions (such as 1.4) aren't removed by the installer, so I need to uninstall them. Everyone is running Windows XP. The neat coincidence is that Sun just got bought by Oracle and Oracle has now changed all the instances of "Sun" to "Oracle" in Java. So, I can conveniently not have to worry about uninstalling the latest Java, because I can just do a search and uninstall all Sun Java programs. I found the following batch script on a forum post which looked promising: @echo off & cls Rem List all Installation subkeys from uninstall key. echo Searching Registry for Java Installs for /f %%I in ('reg query HKLM\SOFTWARE\microsoft\windows\currentversion\uninstall') do echo %%I | find "{" > nul && call :All-Installations %%I echo Search Complete.. goto :EOF :All-Installations Rem Filter out all but the Sun Installations for /f "tokens=2*" %%T in ('reg query %1 /v Publisher 2^> nul') do echo %%U | find "Sun" > nul && call :Sun-Installations %1 goto :EOF :Sun-Installations Rem Filter out all but the Sun-Java Installations. Note the tilda + n, which drops all the subkeys from the path for /f "tokens=2*" %%T in ('reg query %1 /v DisplayName 2^> nul') do echo . Uninstalling - %%U: | find "Java" && call :Sun-Java-Installs %~n1 goto :EOF :Sun-Java-Installs Rem Run Uninstaller for the installation MsiExec.exe /x%1 /qb echo . Uninstall Complete, Resuming Search.. goto :EOF However, when I run the script, I get the following output: Searching Registry for Java Installs 'DEV_24x6' is not recognized as an internal or external command, operable program or batch file. 'SUBSYS_542214F1' is not recognized as an internal or external command, operable program or batch file. And then it appears to hang and I ctrl-c to stop it. Reading through the script, I don't understand everything, but I don't know why it is trying to run pieces of registry keys as programs. What is wrong with the batch script? How can I fix it, so that I can move on to somehow turning it into a MSI and deploying it to everyone to clean up this office? Or alternatively, can you suggest a better solution or existing MSI file to do what I need? I just want to make sure to get all the old versions of Java off of everyone's computers, since I've heard of exploits that cause web pages to load using old versions of Java and I want to avoid those.

    I'm trying to just execute the java command and it's saying it cannot be found, even though it is there. Here's what my output looks like root@oneiric:/usr/lib/jvm/default-java/bin# ls -al java -rwxrwxrwx 1 uucp 143 5750 2012-09-20 11:14 java root@oneiric:/usr/lib/jvm/default-java/bin# ./java -su: ./java: No such file or directory So the ls shows it's there, but it doesn't seem to execute. Can someone explain why this is?

  • C# Java Objective-C need expert advices

    - by Kevino
    Which platform as the edge today in 2012 with the rise of cloud computing, mobile development and the revolution of HTML5/Javascript between J2EE, .Net framework and IOS Objective-C ??? I want to start learning 1 language between Java, C# and Objective-C and get back into programming after 14 years and I don't know which to choose I need expert advices... I already know a little C++ and I remember my concepts in example pointers arithmetic, class etc so I tend to prefer learning C# and Objective-C but I've been told by some experienced programmers that Windows 8 could flop and .Net could be going away slowly since C++ and Html5/Javascript could be king in mobile is that true ? and that C# is more advanced compared to Java with Linq/Lambda... but not truly as portable if we consider android, etc but Java as a lot going for him too Scala, Clojure, Groovy, JRuby, JPython etc etc so I am lost Please help me, and don't close this right away I really need help and expert advices thanks you very much ANSWER : ElYusubov : thanks for everything please continue with the answers/explanations I just did some native C++ in dos mode in 1998 before Cli and .Net I don't know the STL,Templates, Win32 or COM but I remember a little the concept of memory management and oop etc I already played around a little with C# 1.0 in 2002 but things changed a lot with linq and lambda... I am here because I talked with some experienced programmers and authors of some the best selling programming books like apress wrox and deitel and they told me a few things are likely to happen like .Net could be on his way out because of Html5/Javascript combo could kill xaml and C++ native apps on mobile dev will outperform them by a lot... Secondly ios and android are getting so popular that mobile dev is the future so Objective-C is very hard to ignore so why get tied down in Windows long term (.Net) compared to Java (android)... but again android is very fragmented, they also said Windows 8 RT will give you access to only a small part of the .Net framework... so that's what they think so I don't know which direction to choose I wanted to learn C# & .Net but what if it die off or Windows 8 flop Windows Phone marketshare really can't compare to ios... so I'll be stuck that's why I worry is Java safer long term or more versatile if you want 'cause of the support for android ??

  • JavaOne Session Report - Java ME SDK 3.2

    - by Janice J. Heiss
    Oracle Product Manager for Java ME SDK, Sungmoon Cho, presented a session, "Developing Java Mobile and Embedded Applications with Java ME SDK 3.2,” wherein he covered the basic new features of the Java ME Platform SDK 3.2, a state-of-the-art toolbox for developing mobile and embedded applications. The session began with a summary of the four main components of Java ME SDK. A device emulator allows developers to quickly run and test applications before commercialization. It supports CLDC/MIDP CLDC/IMP.NG and CLC/AGUI. A development environment assists writing, running debugging and deploying and enables on-device debugging. Samples provide developers with useful codes and frameworks. IDE Plugins – NetBeans and Eclipse – equip developers with CPU Profiler, Memory Monitor, Network Monitor, and Device Selector. This means that manual integration is no longer necessary. Cho then talked about the Java ME SDK’s on-device tooling architecture: * Java ME SDK provides an architecture ideal for on-device-debugging.* Device Manager plays the central role by managing different devices whether it is the emulator or a device that Oracle provides or recommends or a third party device as long as the devices have a Java Runtime that supports the protocol that is designated.* The Emulator provides an accurate emulation, since it uses the same code base used in Oracle’s Java ME runtime.* The Universal Emulator Interface (UEI) makes it easy for IDEs to detect the platform.He then focused on the Java ME SDK release highlights, which include: * Implementation and support for the new Oracle® Java Wireless Client 3.2 runtime and the Oracle® Java ME Embedded runtime. A full emulation for the runtime is provided.* Support for JSR 228, the Information Module Profile-Next Generation API (IMP-NG). This is a new profile for embedded devices. * A new Custom Device Skin Creator.* An Eclipse plugin for CLDC/MIDP.* Profiling, Network monitoring, and Memory monitoring are now integrated with the NetBeans profiling tools.* Java ME SDK Update CenterCho summarized the main features: IDE Integration (NetBeans and Eclipse) enables developers to write, run, profile, and debug their applications on their favorite IDE. CPU ProfilerThis enables developers to more quickly detect the hot spot and where CPU time is being used. They can double click the method to jump directly into the source code.Memory Monitor Developers can monitor objects and memory usage in real time.Debugger on the Emulator and DeviceDevelopers can run their applications step by step, and inspect the variables to pinpoint the problem. The debugging can take place either on the emulator or the device.Embedded Application DevelopmentIMP-NG, Device Access, Logging, and AMS API Support are now available.On-Device ToolingConnect your device to your computer, and run and debug the application right on your device.Custom Device Skin CreatorDefine your own device and test on an environment that is closest to your target device. The informative session concluded with a demo that showed more concretely how to apply the new features in Java ME SDK 3.2.

  • Is there iPhone simulator on iPhone SDK 3.2?

    - by Eonil
    I'm considering upgrade SDK 3.1.3 to 3.2 because 3.1.3 disappeared on Apple's website. I used 3.2 SDK beta once, and any project launched iPad simulator only. (even iPhone project) Is there iPhone simulator on SDK 3.2? Or how to test iPhone app on SDK 3.2? PS. I have to check this before install because this is my main workstation, so I cannot put this into unstable or unusable state.

  • Java EE without Application Server

    - by deamon
    Since EJB 3 we have embeddable EJB containers, JPA implementations can be used without an application server, there is Weld for contexts and dependency injection and so on. Since on many systems is only Tomcat available, I wonder, if Java EE could be used without an application server but with a Servlet container like Tomcat. What would I have to do to set up an Java environment? What drawbacks do you see?

  • ASP.NET MVC framework port for Java EE?

    - by Adam Asham
    So I've played some with the new, not yet final release of ASP.NET MVC framework and I find it to be very nice and elegant. However at work we are tied to Java for the time being, so I'm wondering this: is there a port of the framework out there for Java people like myself? I realize that webforms isn't going to be available unfortunately but what about the routing framework? /Adam

  • Processing image data in java me

    - by Trimack
    Hi, I want to process raw data from a picture taken in java me with byte[] snap = videoControl.getSnapshot(encoding); My question is, whether I should try working already with snap or should I first create the image from this array Image im = Image.createImage(snap, 0, snap.length); and then work with that? Or is there some better documentation of both methods, i.e. getSnapshot and createImage than the Java API reference?

  • Learning advanced java skills

    - by moe
    I've been programming in java for a while and I really like the language, I've mostly just done game programming, but I want to get a feel for some of the more commonly used api's and frameworks and just get a generally more well-rounded grasp of the language and the common libraries in the current job market. From what I found things like spring, hibernate, and GWT are pretty in demand right now. I looked at some tutorials online and they weren't hard to follow but I really felt like I had no context for what I was learning - I had no idea how any of it would be use in a real work environment. I know nothing can rival the benefit I'd get from actual work experience but that's not an option for me right now, I need another way to learn these technologies in a way where I'll at least feel comfortable working with them and know what I'm doing beyond just understanding what code does what. I checked out a few books but they were all really old(like pre-2006, am I right to assume those books would be kind of out of date today?) or required experience with libraries that I didn't have and can't get. I hate getting stuck looking for the best resource to learn something instead of spending my time actually learning. All I really want is someone to point me to a resource(website or ebook) that is aimed at already experienced java developers and will not only teach me some interesting useful java technology(anything that is useful, I dont know much outside of graphics libraries and game related things so I was thinking some database or web programming api's) but also give me a good perspective of it and leave me feeling confident that I could actually use what I learned on a practical application. If my post makes you think I'm not yet experienced to be learning these things, which I doubted earlier today but am now starting to question, then what do you think is the next step for me? I just want to get better at java. Thanks everyone
