from above error information,it told me that no dataSource would be
injected and then there was no jdbcTemplate instance existed in
AnnotatedDao.java.

Hi,

It's strange, I've tried it using eclipse and it works fine. How are
you generating the eclipse project? With maven eclipse:eclipse?

Hi，sorry,I have resolved that problem,becasue I once used the older
version embedded-database(0.13RC1) ,now I have updated it to
0.13RC2,it is ok,thanks.

JK.Webster

[Adolfo Estevez]

It's fine.

I will release next week the 0.1.3 - release version that contains an
updated&refactored version of the case study (and all the examples).
Now I think it's easier to understand. Also I will update the whole
documentation.


Take care

Adolfo

[mens jamie]

Good,Adolfo,I am pleased to hear that you will release the
0.13,congratuation.
PS,if you can,I hope you can give us a architecture graph about
jEmbedded container,and a description grapht about the case study.

Thanks.

[Adolfo Estevez]

Hi,

 

Don´t worry as I´m gonna write a document about the case study. As I have integrated the jIntegrationTest within the framework I have reworked all the examples too, so I will rehash the docs examples.

 

I have added a new annotation @Composition (similar to @Inject, but the lifecycle of the injected service will be handled by the owner service) and a few more things.

 

Thanks

 

Adolfo
