"This package provides support for Channel Access Version 3. The server allows an existing Channel Access client to access a javaIOC database. The client allows the javaIOC to communicate with a Version 3 server, e.g. a javaIOC database can have links to records in a V3 IOC database." - from package.html You are right, they are optional.

I'm assuming it derives from optional use of a pvAccess server in a pvIOC. Does that mean that, if one confined one's use of the core EPICS V4 modules (pvDataJava, pvIOCJava and pvAccessJava) functionally to ChannelRPC, and so did not use a pvAccess server, that one could omit caj and jca from a download (assuming you were downloading the byte-code jars and just running with them in the classpath, as opposed to building from source, in which case you'd need them to resolve compile time symbols). > > Greg > > On 28 Nov 2011, at 17:26, Greg White wrote: > >> Sure, I omitted SWT deliberately, assuming it's not necessary, it's only desirable for developers. >> Basically my mail was driven by the status of this RemoteTea.jar thing - what is that *Marty*? >> >> I understood the interdependencies and got them from the poms (poms should be plural, we don't >> have one pom but I think we should for the objective of making it easier for someone to get started). >> >> Cheers >> Greg >> >> On 28 Nov 2011, at 17:09, Matej Sekoranja wrote: >> >>> Hi, >>>> Can I confirm what files constitute a the minimum runtime install for EPICS V4 in its java binding, necessary to run either a server or a client, of any "type" (ChannelRPC, ChannelPutGet, etc)?

Of those more than half (64) have maven in their name, so are presumably just maven. That leaves ~40 unaccounted for, so I wanted to check they're all either maven prerequisites or pvService prerequisites. >>>> >>>> If this list of 5 is right, I'll make them available as downloads from sourceforge. >>> >>> pvData is standalone. >>> pvAccess requires pvData. >>> >>> pvIOC requires jca, caj, SWT and RemoteTra oncrpc JAR.
