I was running a streamer application on Ameritrade when it asked for a Java upgrade which I did. After that, when I ran the application it would close the Ameritrade window without an error message. I deleted the old environment but that didn't help. I've tried looking for earlier Java programs on thier site but when I go to the free download or try to verify my Java program it closes the window again with no error just like what it did to the Ameritrade streamer application. Help!!
try enabling verbose output. You can do this from the java control panel. Under the runtime settings add the "-verbose" flag. Next time you start the java plugin you'll see a command prompt start up. Any fatal error might be printed there. You can get a stack dump by hitting the \ + break key in the command prompt window (before the plugin exits). - Sometimes a java program might exit due to a JNI error, If you are using native libraries you could check errors there by adding the "-Xcheck:jni" parameter to the plugin runtime settings.
