'[1.2.4] error deploying app to gae [1.4.0] / [1.6.0]

[sas]

I'm trying to deploy this app to gae (it's the spanish translation of
play 1.x, here's it's runnign on gae: http://playdoces-opensas.rhcloud.com/)

I tried with gae module 1.4.0, with the sdk 1.4.0, and with the modeul
1.6.0, with gae sdk 1.6.0 and 1.6.5

In every case I get the same error:

seems like there some trouble with the DocViewer plugin

DocViewerPlugin : Unsupported major.minor version 51.0

Anybody else had a similar trouble?

that is a java compiler class version error. you need to use jdk 6
and it looks like you're using jdk 5 somewhere.

i'd recommend using the oracle jdk 6. openjdk is fine most of the
time, but not all the time. :)

Yikes!

I'm sorry, it's a known issue (at least it was known to me)

I have both jdk6 and jdk7 installed, and play around with one or
another

gae deployment is not working (yet at least) with jdk 7...

I've redeployed, with gae 1.6, and everything seems to work fine

here it is: http://playdoces.appspot.com/

thanks a lot
