I try to start weld 1.1.0.Final on GAE withou succes. 1.0.1 works fine.

One more problem is logging. GAE use common logger. How to use slf4j and weld log injection together. If I include slf4j I have this error:

SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in [jar:file:/G:/ideaworkspace/richgost/target/agost/WEB-INF/lib/slf4j-jdk14-1.6.1.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in [jar:file:/G:/ideaworkspace/richgost/target/agost/WEB-INF/lib/weld-servlet-1.1.0.Final.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.

Logger problem is partially solved. Weld-servlet contains slf4j, but if I inject logger in ViewScoped or SessionScoped beans I get an error, so old play private static final logger pattern is used.

Any solution found for this problem? i've got the same ...

I suspect not. The problem is fixed in trunk. You would also wait for 1.2 Would you be able to report positive or negative results if any?
