Approcket for Java apps ?

[Maxime]

Hi,

This might be a stupid question but I am not able to find the answer
(and I am new to appengine):
is AppRocket compatible with a Java app ?

If not, does a workaround exist to be able to use this apparently nice
software ?

Thanks in advance,
Maxime.

Hi,

An update of my investigations:
As a workaround of a lack of Java app support I created a python
version of the same app (I read it should work).
I followed all the configuration steps and mysql tables are correctly
created in db.

I am trying to sync 3 entities (kinds):
JDO_Store
OpenCalaisSingleResult, that is contained in JDO_Store as an ArrayList
WikipediaSingleResult, that is as well contain in JDO_Store as an
ArrayList

I created the 2 indexes in index.yaml:

- kind: OpenCalaisSingleResult
ancestor: yes
properties:
- name: RawOpenCalaisResults_INTEGER_IDX
direction: asc

- kind: WikipediaSingleResult
ancestor: yes
properties:
- name: WikipediaResults_INTEGER_IDX
direction: asc

and I added the timestamp property to each entity, each initialized
with the actual date of my timezone (in java).

Then when I run daemon.py I get those 3 errors:

Does anybody know why I am receiving no result ?
What checks can I perform to find the root problem ?

BTW, I am new to python...

Thank you,
Maxime.
