Java works, but not for local files
I am using Opera 10.53 and have Java 1.6 u20. It works great. I can run all the apps here for example,http://java.sun.com/applets/jdk/1.4/index.html
I can't run Java apps locally though. I have folder with an index.html and the class files. I'm using Win7 and the java icon appears in the tray so java loads. The local Java app loads fine in Chrome and IE from the folder.
I went through all the Java threads and opera:config is good the plugins are good (none in C:program files/opera....) Again, Java applets work fine from the web. Seems like maybe a security issue or something? I thought maybe a Win7 issue, but they work in Chrome and IE locally so...
The html file loads and the where the Java app should be it says error and you can get more details which are below:

Basically I just started Opera Unite webserver and pointed to the folder where I have my local java apps. Then I just access them through the opera unite url and they work fine.
A little bit of a pain, but hey, it works.
