How do I change encryption mode in qt crypto?

I don't know much about QCA, but according to the documentation QCA::Cipher provides a Mode enum, so you can probably use this class to create a cipher with the mode your server is expecting.

If you are not sure what that mode would be, have a look at the Java code. If it is some non-standard mode, it should be set somewhere in the code. Otherwise, it would be the default that BouncyCastle uses, so you should look at it's documentation to find out what that default is.
