I want to access Domino data via the Domino Access Services (DAS) as REST provider in java eg
String url = "http://malin1/fakenames.nsf/api/data/collections/name/groups";
ObjectMapper mapper = new ObjectMapper();
JsonFactory factory = new JsonFactory();
JsonParser parser = factory.createParser(new URL(url));
JsonNode rootNode = mapper.readTree(parser);
however, I notice DAS binds the JSON in square brackets:
[
{
"@entryid":"1-D68BB54DEA77AC8085256B700078923E",
"@unid":"D68BB54DEA77AC8085256B700078923E",
"@noteid":"1182",
"@position":"1",
"@read":true,
"@siblings":3,
"@form":"Group",
"name":"LocalDomainAdmins",
"description":"This group should contain all Domino administrators in your domain. Most system databases and templates give people in this group Manager access."
},
{
"@entryid":"3-9E6EABBF405A1A9985256B020060E64E",
"@unid":"9E6EABBF405A1A9985256B020060E64E",
"@noteid":"F46",
"@position":"3",
"@read":true,
"@siblings":3,
"@form":"Group",
"name":"OtherDomainServers",
"description":"You should add all Domino servers in other domains with which you commonly replicate to this group."
}
]
How can I easily get rid of these brackets?
As already mentioned you should leave them intact. You can parse theJSON array for example with Jackson.
find an example snippet below
import org.codehaus.jackson.JsonNode;
import org.codehaus.jackson.JsonProcessingException;
import org.codehaus.jackson.map.ObjectMapper;
...
String response = ... your posted string
ObjectMapper mapper = new ObjectMapper();
try {
JsonNode taskIdsjsonNode = mapper.readTree(response);
for (JsonNode next : taskIdsjsonNode) {
System.out.printf("%s: %s%n", "@entryid", next.get("@entryid"));
System.out.printf("%s: %s%n", "name", next.get("name"));
}
} catch (.... ) {
// your exception handling goes here
}
output
@entryid: "1-D68BB54DEA77AC8085256B700078923E"
name: "LocalDomainAdmins"
@entryid: "3-9E6EABBF405A1A9985256B020060E64E"
name: "OtherDomainServers"
The brackets are not nasty but a correct notation. To access the contens just use [0] in your client side script or with your JSON parser in Java you like.
Perhaps the explanation here can help:
Basically you establish a call to DAS via the Jersey client and then you parse the json via Jackson library to a map in java.
During the parsing process you can define which values you want to parse and transform them.
