  • It depends how you call the REST call in Java. Can you please share the implementation details and log output? – Alparslan Avci Dec 19 '18 at 15:30
  • I am using spring boot rest template – Manayam Srivalli Dec 19 '18 at 16:21
  • HttpHeaders headers = new HttpHeaders(); headers .setContentType(MediaType.APPLICATION_JSON);URI uri = new URI(https://hostname:port/hazelcast/rest/mancenter/wan/sync/map?clustername&groupname&mapname); HttpEntity entity = new HttpEntity(headers); restTemplate.excahnge(uri,HttpMethod.POST,entity,JsonNode.class) @AlparslanAvci – Manayam Srivalli Dec 19 '18 at 16:36
  • org.springframework.web.client.HttpServerErrorException: 500 Internal Server Error. – Manayam Srivalli Dec 19 '18 at 17:33
  • Iam trying from last two days ,I didnt get any other error other than 500 but when I change any thing in url it is giving 400,or if I change any host name,then it shows unknown hostname.is there any details you need – Manayam Srivalli Dec 19 '18 at 17:36
  • Can you please try to send with content type `APPLICATION_FORM_URLENCODED ` instead of `APPLICATION_JSON` as in the example here: https://stackoverflow.com/a/38388168/3327350? – Alparslan Avci Dec 26 '18 at 17:10
  • Hi I am able to do sync operation through rest call between two clusters .Previously I used data as JsonNode in HttpEntity,But I need to pass data as String to post .I changes that one and I able to do sync through rest call in java client – Manayam Srivalli Jan 10 '19 at 20:10
  • Thank you so much for your response @AlparslanAvci.I have one doubt .when we are doing the sync operation we want to lock our hazelcast map operations .Is there any way to do in hazelcast.@AlparslanAvci – Manayam Srivalli Jan 10 '19 at 20:14
