Couchbase View query w/ Java: how to quote startkey?
/*

package CouchbaseView;

public class App {
public static void main(String args[]) {
String key = "key";
String value = "Hello World";
if (args.length > 0) { key = args[0]; }

CouchbaseClient cbc;
try {
List<URI> baseURIs = new ArrayList<URI>();
baseURIs.add(new URI("http://10.4.2.13:8091/pools"));
cbc = new CouchbaseClient(baseURIs, "default", "");
View view = cbc.getView("dev_my_app", "by_level");
Query myQuery = new Query();
/* This works from the shell, but how to get Java to quote OK?
$ curl 'http://10.4.2.13:8092/default/_design/my_app/_view/by_level?startkey=%5B"Level+2"%5D&endkey=%5B"Level+3"%5D'
{"total_rows":12,"rows":[

}
I get the following output when I run the program:
Query string '?startkey="%5B"Level+2"%5D"'

myQuery.setRangeStart("%5B\"Level+2\"%5D");

ViewResponse queryResults = cbc.query(view, myQuery);
Iterator<ViewRow> walkthrough = queryResults.iterator();
System.err.println("Found " + queryResults.size() + " docs.");
while (walkthrough.hasNext()) {
ViewRow row = walkthrough.next();
System.err.println("id: " + row.getId()
+ ", info: " + row.getKey()
+ ", score: " + row.getValue()

}
System.exit(0);
} catch (Exception e) {
System.err.println("Error testing Couchbase: " + e);
System.exit(1);
}
