Java :: Accesing A File When Deploying In Tomcat A Flex Application?
May 22, 2011
I have two applications: a client in flex and a server in Java. When I deploying the application inside flex builder with the tomcat server inside as well, everything works fine. But now I'm trying to deploy in apache tomcat outside the flex/eclipse builder and I have a problem.I think the problem is with relative/absolute paths but I do not know how to resolve it.In my Java application I have to access a database and a get a file from it. I use a properties to set a path where I want to download that files like this:pacs.ruta=C:\resources\And then I need to access to that file so in use this code:fin = new FileInputStream(pacsRuta+""+f.getName());where f.getName() gives me the name of the file so I get the path of the file with the path I set in pacs.ruta and the files name.
I do not know why it does not work. I tried to put pacs.ruta=/resources/to associate with a folder in my application but It does not work.Could someone give me an advice? Do you think it is the problem? Because the whole application works fine deploying in a tomcat server outside the flex/eclipse builder but when this code is called the application does not work.
I write a flex + java application using the blazeds framework. when i write log files in my java classes the default path is the java path on the server. I want it to be my application at the tomcat/webapps/application directory when i write it hard-coded it failed (maybe bacause of permissions) but, i want it to be general (not hard-coded) so, what do i need to change in my java code in order to write files in my webapps directory? maybe it just an xml configuration?
I am using Flash builder 4 (SDK3.5) to create my flex program.I want to deploy this program and load it to a tomcat server.I configure my "flex server" root folder and other parameters in the project properties.The problem is, that i don't know how to make it generic. e.g. my friend's tomcat is installed in other directory on the computer. I know that in eclipse i can run the server and tomcat from the IDE. I can't see how i do it in Flash builder plugin for eclipse 4.
i am working on a flex+java combined project.My IDE and computer configuration is as follows:
[Code]...
When i make a small change in Flex code (eg, reposition of a button...anything), and run the project on server, it does make any change on output. Actually it depends on my luck... because it makes change in output randomly.what is is happening? tried rebuild, republish, clean , restart server, restarting the IDE, restarting the computer all available feature i could think. Also, i created a simple flex project on IDE and compiled it..... everything is compiled and displayed on output.
I'm coding a web app in flex blazeds and Java. I installed the Eclipse plugins for using WTP mixed project. I'm using flex's server that uses an emulate of tomcat when i ran my flex service the web app got the datas, everythings is ok. the problem is when i copy the project with all files generated by flex in my tomcat or the blazeds's tomcat, it doesn't work, this is becasue i want to implement my app on a server the error is:[code] i don't know why tomcat doesn't find the class of flex.messaging.endpoints.AMFEndpoint that is used for my-amf 'URL...'. all works well in the emulated server that flex has.
I have one flex project in maven.I am able to package and install it without any problems, but I am not able to deploy it:[code]I have already increased maximum allocated memory (set MAVEN_OPTS=-Xms2512m -Xmx3512m), no success.[code]
One of my web applications have developed in java and using tomcat server. Now I want add one more feature in my application that is peer to peer audio streaming. Actually I want that anyone speak (using microphone) on the client side and I will hear his voice on my server speakers and vice versa. Also save our communication in any file and also send the audio stream to IP intercom.
For that I am trying to use Flex Builder. Flex NetStream class is good for the streaming and we can also attached microphone. But the problem is on the server side. How can I get the audio stream on server side?
how can I get stream from server to client and vice versa?
I've followed the getting started for BlazeDS. I'm making changes to the Flex code using Flex Builder 3, but I just can't get the changes to show up when I refresh the page on my client. Server and client are separate physical machines, I've even re-started the server hardware. One curious thing, even when I re-started the server I didn't have to re-login to the Tomcat manager page
I'm developing a web application (client in Flash Builder 4, server in Eclipse 3.6 + Tomcat 7 + Spring 3 Framework). How do I make the Flex client automatically deploy in the Tomcat server and use BlazeDS messaging and remoting more seamlessly?
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?
I am trying to develop one simple application using Java, Flex and Blazeds. I am using Flash builder 4.5, blazeds 4 and JBoss 6.I have created 'Dynamic Web' application in Eclipse, added blazeds related file in WEB-INF/lib and in WEB-INF/flex folder. I have deployed this web application in JBoss using Eclipse, so this application is getting deployed in war file.Then I tried to create new 'Flex Project' using flash builder 4.5 and I am stuck in 2nd step where we have to configure Root Folder, Root URL and Context Root.As my java web application is deployed in war, there's no folder to which I can set Root Folder.
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'm currently working on a project that need to communicate with java from air without the use of a server like Tomcat. For this i found and use Flerry.Communicating between Java and Air is no problem, as long as I try to send a message from the class that I initially instantiated from Air.What I try to do is subscript to messages from a Message Class in java and use that class to send info and errors to Air from Java.
MessageController.java:
public class MessageController {[code]....
the infoMessageHandler receives an message containing test message, as it should. How can I dispatch messages from whatever class in Java and catch them on the Air side?
I have a Flex/Java/MySQL/Hibernate application running on tomcat/BlazeDS which have very LOW activity, the user can even not visit it for months.The problem that after a month of inactivity the connections between tomcat and mysql are closed and then I need to restart both the mysql and tomcat servers, is there a way to avoid that and maintain the connection always open?
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 tried with flex and java in the backend. In this, I am able to upload files till 100 MB using remote object (blazeDs) where we will read the file as byte array and send it to the java method. If the file size exceeds after that, then I get the run time error in IE.
I could play MIDI file where "filename" is a String type with "asd.mid" value. However, I tried to sent AIR's nativeprocess command to Java, it shown "could not read" error.
I am newer with flex technology.I am creating a chart using ant file & .mxml in eclipse my 'ant' file executes properly but it gives following error when i opens a .swf file which is created auomatically:
Flex Error #1002: Flash Player 9.0.115 and above is required to support signed RSLs. Problem occurred when trying to load the RSL
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:
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 just learning about Flex and I'm loving it. Unfortunatly I still have to make the decision on which RIA technology to use and its dependent on, among other things, from the following case: How can we wrap a java applet around a Flex application? More specifically, I would like to wrap/integrate NASA's World Wind applet in a Flex panel, similar to what Adrew Trice did with the Google Earth API.
An alternative would be id Flex would support direct access to the 3D hardware through OpenGL or DirectX. But I do not think that that is the case yet, not even through AIR.
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?
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 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 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?
