Cannot add new providers in servlet???

[Chinh Tran Nam]

Hello,

I use Entrust toolkit for sending encrypted messages. I wroted a sample
application and it worked on IDE runtime environment. However, it failed
when I migrated to servlet and here is the code statement that caused the
problem:

Initializer.getInstance().setProviders(Initializer.MODE_NORMAL);

The exception it threw was: java.lang.NullPointerException

Please advice?

Thanks
