“Automatic updates” for Java (desktop) application?

阅读更多关于 “Automatic updates” for Java (desktop) application?

What system do you recommend for implementing "automatic updates" for some java (desktop) application? I'd also want to have module/plugin installation and update. Think Eclipse and Firefox. I'm aware of Eclipse RCP's OSGi stuff, and also NetBeans RCP has something here. Do one have to buy wholly into their respective RCP stuff to use their module and automatic update systems? Are there other options? Ma99uS Have you looked at the Java Web Start ? It checks for updated module on the server and downloads it only if required otherwise things are cached locally on the client PC and starts from

问题 How can i make a Java program which can update itself. I make this program for use within small team. I do not need any advanced features. I just need a simple and minimal solution. 回答1: Java Web Start is meant specifically for this. You ship one jnlp file, and java takes care of fetching the newest version from a server. Apart from that, you can download updated classes and replace them at runtime. 回答2: What do you mean by self-updating ? If you mean that it changes its behavior at runtime

Currently I'm checking the app version code on launch and match it with latest version code on my server and based on this matching I send user to get latest update from Android market. It's working well but my problem is that I have to manually change the latest version code on my server and I don't know exactly when new version of APK gets activated in market. Is there any way to check version code of app in Android market directly so that I can send user directly to market when new apk gets activated? Google Play does not provide any official APIs for retrieving metadata. You could however,

问题 I am developing a library for Android that requires frequent updates from a central server. I was thinking how nice it would be if my library could update itself -- or if I could just release a bootstrap library that downloads the target library when the app is installed. I see this class in 1.5 called "DexClassLoader" but there seems to be precious little on the web besides the API docs. Has anyone used this successfully for the scenario which I described? Also, do the terms of the Android

问题 I have written a script that will keep itself up to date by downloading the latest version from a website and overwriting the running script. I am not sure what the best way to restart the script after it has been updated. Any ideas? I don't really want to have a separate update script. oh and it has to work on both linux/windows too. 回答1: In Linux, or any other form of unix, os.execl and friends are a good choice for this -- you just need to re-exec sys.executable with the same parameters it

How can I execute something just once per application start?

阅读更多关于 How can I execute something just once per application start?

I'd like to implement an update checker in an application, and I obviously only need this to show up once when you start the application. If I do the call in the onCreate() or onStart() method, it'll be shown every time the activity is created and this is not a viable solution. So my question is: Is there a way to do something, like check for updates, just once per application start / launch? I'm sorry if it's a bit hard to understand, I'm having difficulties explaning myself on this one. SharedPreferences seems like ugly solution to me. It's much more neat when you use application constructor

How should I implement an auto-updater?

阅读更多关于 How should I implement an auto-updater?

问题 Many programs include an auto-updater, where the program occasionally looks online for updates, and then downloads and applies any updates that are found. Program bugs are fixed, supporting files are modified, and things are (usually) made better. Unfortunately no matter how hard I look, I can't find information on this process anywhere. It seems like the auto-updaters that have been implemented have either been proprietary or not considered important. It seems fairly easy to implement the

Running Microsoft Access as a Scheduled Task

I am seeking comments on how to schedule auto updates of a database (.accdb) since I am not very comfortable with the process I have set up. Currently, it works as follow: Task Scheduler calls a .bat .bat calls a .vbs .vbs opens the database and calls a macro The macro calls a function (VBA Level) The function calls the update Subroutine I consider there are too many steps and the fact that it requires 2 external files (.Bat and .vbs) related to the database and stored on the system increase the risk that the procedure would break. Apparently (but please tell me that I am wrong and how I can
