How can i enable WTP tools in Flash Builder 4.7 for create mixed project java/flex ?

Hello,

I would like create a java/flex project with BlazeDS support.

I'm using Flash Builder 4.7 but i'm not able to add WTP tools (dependency error during installation process).

To workaround this issue, i would like use a regular eclipse installation with a full set of tool (wtp, subclipse, ;..) and add Flash Builer 4.7 plugin.

But i'm not able to found the download like for the plugin version of Flash Builder 4.7.

Please give me the right procedure.

Regards
