title: java web start alternative
body: <p>We're looking for an alternative to Java web start that effectively does the same thing, just better implemented. We're having massive trouble with it. We have a few offices of XP desktops, all slightly different and so far only a handful have worked without serious tweaking. Problems are to do with not playing nicely with the proxy settings (using direct connection in Java control panel allows it to work), refusing to run when params like "-Xmx" are set but running fine when they aren't (until it runs out of memory) and other odd problems that we can't fix. </p>
  
  <p>The way web start works is exactly what we want, i.e. connecting to a server that has the app, downloading anything that's changed, keeping a cache of jars, etc. Other teams here use 'clickonce' for their C# apps and it does effectively the same thing but seems to be less trouble.</p>
  
  <p>I'm convinced we're not the only people to have run into this but searching around doesn't really show any alternatives. We've looked into writing a stub local application that is essentially just a URLClassLoader that loads up our app over the network on the fly but unfortunately that's too slow from other offices. Anyone have any ideas?</p>
  
  <p>Thanks</p>
  
  <p><strong>Update</strong></p>
  
  <p>In case anyone is curious as to what eventually happened, we gave webstart another month or so but continued to run into problems so we implemented our own version. It's basically just a stub that has a URL class loader that you point at a webserver. It's &lt; 200 lines of code and it has been working perfectly for months. It's not ideal but until someone improves webstart we'll stick with it.</p>
  
  <p><strong>Update 2018</strong></p>
  
  <p>So, several years later and I'm working on a new project with the same problem. Instead of writing our own webstart implementation this time we're using <a href="https://github.com/threerings/getdown" rel="nofollow noreferrer" title="getdown github page">getdown</a>. We've found it to be a vast improvement over web start and it's been working really well for us. </p>
