Dear Community, after several attempts I need to say that I must give up my experiments with SCSCP, at least for now. The Symcomp page is now on a completely different topic: "Murphy Beds Wall Bed Designs Ideas", I am unsure if this is intentional or the page has been hacked.
On the other hand, I found the GitHub page https://github.com/symcomp/org.symcomp.openmath which contains the same code as the 1.5.0 bundle. That's fine, but it has not been touched in the last 8 years and it doesn't even compile: .../org.symcomp-1.5.0-src$ *mvn install* [INFO] Scanning for projects...

[ERROR] [ERROR] For more information about the errors and possible solutions, please read the following articles: [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/ProjectBuildingException The reason I tried version 1.5.0 instead of 1.4.0 because I cannot get correctly connected with MapleNet from Java by using the 1.4 SCSCP protocol: finally the connection is dropped by MapleNet. (It sends an "unsupported_CD, <OMS cd = 'scscp_transient_maple' name = 'Differentiate'/>" message.) Maybe this is not the forum to discuss the reason why the connection is rejected (I have a working connection from a normal Maple client with the same OM XML call, so I guess there must be some differences in the SCSCP protocols being used), but it's annoying that I couldn't compile the symcomp package, either. I consider symcomp the official way to connect via SCSCP in Java, so, if it is not maintained any longer, I have mixed feelings on continuing with SCSCP in general. I learned that the Java sources of OMSymbol and others are removed from 1.5.0 and there is only Scala code that seems to jump in for OMSymbol.java and so on, unless the Java code is simply missing from the repository (I'm not a Scala expert, sorry). Thanks for any hints in advance. But now I think it's extremely complicated to set up an SCSCP connection in Java properly with Maple, and since my MapleNet license will expire today, I am unsure if this is the way to go (to send a simple string via http like in SingularWS <https://github.com/kovzol/singularws> seems much simpler and quicker).
