jre 1.6 with GWT

I have an application written in GWT 1.4 I am all set to up grade it to GWT 1.7/2.0 Before starting i just want to confirm that GWT 1.7.1 above versions supports jre 1.6开发者_如何学Go??

From version 1.5 of GWT you can now use the Java 5.0 (JDK 1.5) language constructs as well, e.g. generics, enums. This means that you have a much greater chance of sharing code between the client and server sides of your application, if the server-side is written in Java.

The JRE Emulation Library of GWT supports more methods and has been updated with generics support. But it is still not a complete implementation of the JRE standard library, e.g. no BigDecimal, no file support, etc.

Having said all of that, I am not sure exactly what you mean by "supports jre 1.6"?

GWT. 2.0 requires 1.5 or later. Refer to http://code.google.com/webtoolkit/gettingstarted.html

I have been running with 1.6 for a while now with no issue.
