Re: [Handle-info] Java Client in DMZ (HandleResolver.java)

"Unknown opCode in message: 0" sounds like a response has been sent instead of a request.  How is the "req" object constructed?

What you're doing should work.  I would recommend to use a higher-level method, though, as then you can take advantage of sessions for faster processing.  "sendRequestToSite" would be my preference.  You can get a SiteInfo, for example, from the siteinfo.bin in your handle server directory:

       SiteInfo site = new SiteInfo();
       FileInputStream fin = new FileInputStream("/path/to/siteinfo.bin");
       ByteArrayOutputStream bout = new ByteArrayOutputStream();
       byte buf[] = new byte[2048];
       int r;
       while((r=fin.read(buf))>=0) bout.write(buf, 0, r);
       Encoder.decodeSiteInfoRecord(bout.toByteArray(), 0, site);

"sendRequestToServerByProtocol" would also serve.
