EVALUATION I am reasigning this to net group based on the following: If I configure java web start with both 1.4.0 and tiger (deployment nightly build 9/28) and run tomcat on my ultra (gdisun.east) and attempt to access apps in my tomcat setup: 1.) if I load an app with <j2se version=1.4+ href="..."/> I will get the error shown. In this case it will be running java 1.5.0 when it tries to download. (1.4+ results in the latest configured java at least 1.4) 2.) If I load the same app except with j2se version=1.4* href="..."/> It runs fine. (1.4* forces it to use some 1.4 version, in this case 1.4.0 is configured) ###@###.### 2003-09-20 ------------------------------------ One change that happened in b18 is that we now force all http transactions to go through the proxy (when a proxy is set). Formerly, if the connect attempt through a proxy failed, then we retried with a direct connection. This behavior was not documented, and was surprising in many respects. The particular problem here is that the address 127.0.0.1 will never be accessible via a proxy (hence the 500 error from the proxy). I think the original behavior where we retry directly was wrong and the correct thing to do, is to specify 127.0.0.1 in the list of non proxy hosts. ###@###.### 2003-09-23 We will put in the special casing of loopback addresses to keep backward compatibility. ###@###.### 2003-10-07
