Re: Java API JCA / CAJ DBR_LONG

Hi,

Is ca the successor to JCAE:

  https://github.com/paulscherrerinstitute/jcae

Both are developed at PSI, no?

Are both used in production?  Are both supported?  What does the future
of JCAE look like?

I do not know JCAE. Quickly looking at the code it is a wrapper around JCA.

I was funded by PSI to write “ca”. I reused stable CAJ core but ditched old JCA interfaces

and replaced them with modern Java 8 interfaces. Afterwards PSI took over and added more

features.

One thing I note is that it appears that JCAE has a client *and* a
server implementation, while ca has just a client.  Is that right?

Right.

Are there plans to add a server implementation to ca?

I do not know.

However, CAJ server side interfaces are more modern than JCA

(but CAJS still use JCA DBR classes instead of generics).

Would JCAE still be a sound choice for a new project that needed a
client *and* a server implementation, or even a sound choice for a
project that needed just a server implementation?  Or would it be better
to avoid it because it's being phased out, instead going with ca for the
client and CAJ (even though dated) for the server?

I would go with ca client + CAJ server.

Cheers,

Matej
