SSL communication with external app not working.

[H. K]

Hi,

at first let me say that i am a newbie in developing apps for the "Google App Engine".
What i try to achieve is to port our existing application (Java) to run on the "Google App Engine".

However the application will need to transfer data via SSL with an external site.
Now i am using classes from "javax.net.ssl.*" to achieve this.
But when i try to use them i get the error "javax.net.ssl.SSLSocketFactory is not supported by Google App Engine's Java runtime environment"
(I did find this whitelist of supported classes and "javax.net.*" is not listed.)

Is there a workaround of how i could use these classes, or is this prohibited ?

Moreover my current app needs that additional "root certificates" are added to the JRE's cert store. (Now i do this with "keytool.exe" )
Would this even be possible to add these in a "Google App Engine"-application ?

Thank you in advance
