Java :: Controlling A USB Device From A Web Application?
Aug 17, 2010
I would like to be able to control a USB device from a web application. I was hoping to use Adobe Flex but I don't think that Flex can support access to USB devices.Is this possible using Java applets, or a similar approach using .NET?
I'm programming Rich web applications with Flex and Java on Flex Builder 3 using blazeDS and SharedObjects.Now I need that my program will use configuration file.so, I need that my Java class will read it at the first time but the default path of java to read and write files is c:program filesFlex Builder 3 and not my application directory inside the tomcat webapps directory How can I read the config file from the java class without write the path hardcoded in the java?
I am having an issue with my Adobe AIR application for android devices. When running the SWF file on the PC the application runs perfectly, I have also tested this in adobe Device Central and it works as expected. When I install this application to my android device, a HTC Desire HD, I get a screen with 5 dots, seems like a loading screen.I created the application using the following command
I have a grails application using jquery mobile. I am hoping to find some way to access the camera on the devices. I thought about using flash to grab the webcam but that obviously wont work on Apple devices. Does anyone know of a way to do it and keep it all browser based? I am hoping that there is a plugin somewhere or maybe html5 has some magic in there that supports it.
I have imported my wav files to my library added them to the down state of my buttons and when I test the file I get (Sound has no valid device sound path although exporting device sounds was requested in the export settings. This sound will be ignored.) I have been surching for an answer but as of yet have found none.
I have a flex application in which multiple sound files are used in various parts of the application. Can i have a single sound handler, which will take care of volume control fo the entire application at once. How can i do that
I am writing a desktop application and trying to decide between using AIR (FLex) or Java.Some of the requirements for the application are: needing to securely connect to webservices and JMShave a very interactive UI (lots oflittle and big features)displaying videoCommunicate with a C++ applicationTo implement the web services and JMS for Flex we were thinking of using Merapi to communicate with a Java application. Does this mean we should probably go with Java or does the better graphics capabilities of Flex still make it a better choice?
Can Flex be used for a desktop application whose business logic is written using Java? Everything I've read about flex uses a remoting or http protocol to communicate with the backend via a J2EE server, so I'm not sure how that would work for a desktop app (unless an embedded j2ee server was running in the app).
I'm trying to get data from a website, but first I need to log in to the site using java. The script worked until now, but now the site installed an anti bot system. Until now the procedure was simple, I've created a HttpStreamWriter and submitted my details to the login.php page, then get the cookies and later, when I want to get data from the site, I resubmit the cookie from the login.php page, but now there is a problem: an anti bot system: I'm not sure, but I think this is the system: [URL] The anti bot system creates a cookie, called anti-bot and I can't access the page without that cookie, the problem is that the cookie is generated by a flash application only after the page loads so I can't get the cookie from the page?
What's the best way to secure a Flex-BlazeDS application? I've googled it an several solutions came up.UPDATE after question from jsight:Flex would login, so on the RemoteObject I'll set Credentials I don't know if there comes authentication and authorization with BlazeDS (WebORB for instance does and WebORB looked at BlazeDS for their product) SSL not needed 've seen some links on the internet talking about spring security, so I'll check that out.
I developed an application using flex+java+blazeds with tomcat that provide flex enviroment.I want to deploy my application using tomcat but I can't, how can I deploy my app?
I need to do click a button within the admin side of my external website and cause it to trigger an application within my local workstation (with parameters based on button). I have full control of the server, PHP, etc. I can also install any application on my workstation. What is the best way to do this? Adobe AIR/Flash? Java?
What's out there that lets you do this? Are there any OSS projects or maybe something a little more popular than this:[URL]? This does exactly what I'm suggesting (i.e. cuts out the need for Swing UI for the most part) but for a number of reasons I'd be interested in any better alternatives. alternatives would need to support the Flex SDK.
I would like to develop applications for iPhone and Android devices. Which language it is better to use Java or Flash? I have read that Adobe Flash CSS 5.5 support compatibility for ActionScript on both devices. Will be interesting to know plus and minus sides for both languages? Remember that we have to develop application for both devices, and we have a small part of that application already written in Java.
I read through the method to connect to a socket server : [URL]. I wrote an AIR application to connect to the java server code, but the client cannot connect. What is missing in the code?
We know that, with Android NDK we can use .C files along with .java files in a single android application. Similarly, is it possible to use Adobe Flash and Java files in a single android application ?
Did anyone integrated Amobee SDK into Android application on ActionScript or Java?I have AmobeeTracking.jar file, I have to write native extention to integrate Amobee SDK into Adobe AIR application for Android. But I don't know what to really write.
I developed a Adobe Air Application and I discovered that the Mobile I am trying to install the application is not compatible with the Adobe Air's supported devices because this wasn't launched yet.
I have some ideas:
Is possible to change the Mobile Name to fake another device and Adobe Air not refuse the installation? Is possible to convert AIR to Java? s possible to run Air without Java? Abandon Flash and do it in Java or Javascript.
e an application which is talking with Flash clients through sockets. The messages are in XML and not too long, up to 1000 chars. After the update the messages aren't received correctly at the client side - one byte is missing at the end. The first message is correct, the byte is missing from the end of the second message and the Flash stops because of the parse error.
I am using the same java server given there. and I am creating the XmlSocket in a flex air application. When I run my air application I get a java.net.SocketException connection reset at the java server.
I'm trying to create a simple Flash chat application for educational purposes, but I'm stuck trying to send a policy file from my Java server to the Flash app (after several hours of googling with little luck). The policy file request reaches the server that sends a harcoded policy xml back to the app, but the Flash app doesn't seem to react to it at all until it gives me a security sandbox error.
I am struggling to come up with a way to efficiently manage Flex entities that have a many-to-many relationships between their JPA/Java counter parts.[code]Both of these entities can exist independently of each other and both have a 1:M relationship with the other. The relationship is not really owned by one side or the other.Within the application there are Flex UI's that sometimes want to see viewers based on movies and other UI's that want to see movies based on viewers.Currently both the Movies.Viewers and Viewers.Movies collections are lazy loaded by JPA which works fine. The problem is that every time I ask a viewer for it's list of movies, then they all get sent over the wire and then within Flex I end up with a bunch of Movie objects that (often, not always) duplicate the ones I already have there.
It seems inefficient at best and could likely cause errors if the duplicate objects are not dealt with.In my real application I have tons of these types of relationships all over some very large object graphs.It almost seems to me that the lazy loaded object collections need to be turned into eagerly loaded collections of foreign keys which are used to explicitly load objects on the Flex side of things. But this seems like I am writing a JPA provider in Flex! Is the correct answer to never store state in a Flex application? (Yikes)I should add that all my value objects have a UID that is created on the server side, so I could somehow use that to find/remove duplicates on the Flex side. But how?
I have a great idea and I want to build a flex application around a .jar file. Is there a way I can go by embedding a jar file into the flex application?
Currently we are in the design phase of an application that will allow two users to communicate with each other using chat and video (with audio), the application is a web application that currently is a java web app with Spring and hibernate, but we want to incorporate video and chat between two users and we are evaluating the options to developing it, so far we have two choices, either develop a Flex UI that leverages its video and chatting capabilities through Red5 or something like that and communicates with the Spring app using BlazeDS or a completely java based approach using (maybe) JMF and/or applets to achieve the video and chat interaction. The question is, which would be the most scalable approach to develop such an application?, what would be the approach that is the least intrusive from the end user perspective?
Despite my luddite tendencies, I now have a phone with Java support - but no Flash support. I also have a copy of Macromedia Flash MX2004, though I'm unlikely to upgrade any time soon. What I'd like to be able to do is develop some content (including vector animations) in Flash, then use those resources in a Java Micro Edition application. I don't need all features of Flash - in particular, I don't care about ActionScript support. But I do want to be able to load a SWF file (or, perhaps better, an alternative file format that can be generated using a converter tool), and to be able to display animations and use other resources (particularly play sounds) from in that file.
Is there a good library and toolkit to support this kind of thing? Obviously (from the MX2004) it doesn't need to be completely up to date. On knowledge level - I've been a programmer for decades, and my everyday language these days is C++. However, I have a very limited knowledge of Java, and virtually no knowledge (yet) of Micro Edition and its libraries. I've already heard of Flash to J2ME converters, but so far as I can see they generate complete applications in one step, rather than treating the SWF file as a source of resources to be controlled from separately written Java code.
EDIT I get the feeling that this is (with slight modifications) probably quite easy. Java Mobile Edition supports SVG vector graphics. SVG supports animations. There are (I'm pretty certain) ways to convert flash animations to SVG - probably a simple export-to-SVG in the application, though I've not checked. This in itself doesn't give me a convenient bundle-of-media resources file format, but that's a relatively simple problem to solve, so long as there's a way to "load" SVG and other media files from some kind of non-file stream class that gets its data in turn from the bundle-of-media file.
I don't know really well the diference between AIR and FLEX, i do with Java tought, My question is that I want to build an application to run in local mode, but maybe in the future I want it to be available trought the web, The basic sequence diagram is the following: So I want the client to connect to a server for login information, and for storing some data, and I don't know wich one of the three technologies is the best..
I have an Adobe AIR application for Android. Using for this AIR 3.0 and Flash Builder 4.6. I need to make MyANEFile.ane - which must include 2 external .jar files: Flurry.jar + Tapjoy.jar. But when I made .ane file - it does not work. How can I add this 2 jar files to my main application jar file to make .ane file properly? It shows me such errors in dalvik:
