Domain Restriction in BabelNet

I am trying to restrict the results of my BabelNet query to a specific (Babel)domain. To do that, I'm trying to find out a way to compare the synsets' domains with the domain I need (Geographical). However, I'm having trouble getting the right output, since although the 2 strings match, it still gives me the wrong output. I'm surely doing something wrong here, but I'm out of ideas.
After many trials, the following code was the one that gave me the nearest result to the desired output:
public class GeoRestrict {
public static void main(String[] args) throws IOException {
String file = "/path/to/file/testdata.txt";
BabelNet bn = BabelNet.getInstance();
BufferedReader br = new BufferedReader(new FileReader(file));
String word = null;
while ((word = br.readLine()) != null) {
BabelNetQuery query = new BabelNetQuery.Builder(word)
.build();
List<BabelSynset> wordSynset = bn.getSynsets(query);
for (BabelSynset synset : wordSynset) {
BabelSynsetID id = synset.getID();
System.out.println("\n" + "Synset ID for " + word.toUpperCase() + " is: " + id);
HashMap<Domain, Double> domains = synset.getDomains();
Set<Domain> keys = domains.keySet();
String keyString = domains.keySet().toString();
List<String> categories = synset.getDomains().keySet().stream()
.map(domain -> ((BabelDomain) domain).getDomainString())
.collect(Collectors.toList());
for (String category : categories) {
if(keyString.equals(category)) {
System.out.println("The word " + word + " has the domain " + category);
} else {
System.out.println("Nada! " + category);
}
}
}
}
br.close();
}
}
The output looks like this:
Synset ID for TURIN is: bn:00077665n
Nada! Geography and places
Any ideas on how to solve this issue?

I found my own error. For the sake of completeness I'm posting it.
The BabelDomain needs to be declared and specified (before the while-loop), like this:
BabelDomain domain = BabelDomain.GEOGRAPHY_AND_PLACES;

Softlayer - list of servers which are powered on

The following java code lists all the bare metal servers in softlayer for a specific SL account and filters for servers which are powered on (e.g. powerState='on'.
public void listServers(Account.Service service, ApiClient client) throws Exception {
service.withMask().hardware().fullyQualifiedDomainName().primaryIpAddress();
service.withMask().hardware().hardwareStatus();
service.withMask().hardware().id();
Account account = service.getObject();
//
// list of softlayer servers for the client account
//
for (Hardware hardware : account.getHardware()) {
String hostname = hardware.getFullyQualifiedDomainName();
String hardwareStatus = (hardware.getHardwareStatus() == null) ? null : hardware.getHardwareStatus().getStatus();
Long serverId = hardware.getId();
String powerState = null;
if (serverId != null) {
Hardware.Service hardwareService = Hardware.service(client, serverId);
hardwareService.setMask("mask[serverPowerState");
try {
powerState = hardwareService.getServerPowerState();
} catch (Exception ex) {
System.out.println("Error, cannot get powerState, hostname=" + hostname + ", msg=" + ex.getMessage());
}
}
System.out.println("Hostname=" + hostname + ", hwStatus=" + hardwareStatus + ", powerState=" + powerState);
}
}
Code seems to work, but for at least one of the servers, it fails on the call to hardwareService.getServerPowerState()
"Unable to establish IPMI v2 / RMCP+ session".
Any ideas why this is failing ?

How to get all the queues and topics from solace

I want to discover all the destinations from solace (queues and topics)
I tried using MBeanServerConnection and query after names (but I didn't find a proper way to use this) or JNDI lookups Destination dest = (Destination) context.lookup(Dest_name), but I don't have the names of the queues/topics.
I am using solace - jms library.
I am searching for smth like this: (but for solace, not activeMq)
get all Queue from activeMQ

You will need to make use of SEMP over the management interface for this.
Sample commands:
curl -d '<rpc><show><queue><name>*</name></queue></show></rpc>' -u semp_username:semp_password http://your_management_ip:your_management_port/SEMP
curl -d '<rpc><show><topic-endpoint><name>*</name></topic-endpoint></show></rpc>' -u semp_username:semp_password http://your_management_ip:your_management_port/SEMP
Note that I'm using curl for simplicity, but any application can perform HTTP POSTs to execute these commands.
If you are using Java, you can refer to the SempHttpSetRequest sample found within the Solace API samples.
Documentation on SEMP can be found here.
However, the larger question here is why do you need to discover all destinations?
One of the features of the message broker is to decouple the publishers and consumers.
If you need to know if your persistent message is being published to a topic with no consumers, you can make use of the reject-msg-to-sender-on-no-subscription-match setting in the publishing application's client-profile.
This means that the publisher will obtain a negative acknowledgement in the event that it tries to publish a message on a topic that has no matching subscribers.
You can refer to "Handling Guaranteed Messages with No Matches" at https://docs.solace.com/Configuring-and-Managing/Configuring-Client-Profiles.htm for further details.

Here is some source code that might help. With the appliance configured correctly, SEMP is also available over JMS on topic "#SEMP/(router)/SHOW".

You can get message VPN specific queues and topics using following SEMPv2 command.
curl -s -X GET -u semp_user:semp_pass management_host:management_port/SEMP/v2/monitor/msgVpns/{vpn-name}/queues?select="queueName"
curl -s -X GET -u semp_user:semp_pass management_host:management_port/SEMP/v2/monitor/msgVpns/{vpn-name}/topicEndpoints?select="topicEndpointName"

Loading different set of properties in java to an ArrayList

I have a list of properties like this,
server1.serverName =""
server1.serverType ="'
server1.hostName =""
server1.userName =""
server1.password =""
in a property file and I have 'n' no of sets,like
server2, server3,...servern in a property file. And also I have a class which contain all off these elements with getter and setter method,
public class ServerDetails implements Serializable {
private String serverName;
private String serverType;
private String hostName;
private String userName;
private String password;
...
}
Now, I need to read the above property file and create an arraylist like ,
ArrayList<ServerDetails> serverDetailsList = new ArrayList<ServerDetails>();
where each element of the arrayList should have an object of the class ServerDetails. I need to know how to read the property file and get the server details so that I can create an object and add it to the list.
It seems kind of easy but i lost my way. Kindly help.
Thank you !!
Regards,
Bala

You could load the properties file into a Properties object, then loop through the properties like so:
int i = 1;
while( properties.get( "server" + i + ".serverName" ) != null ) {
ServerDetails details = new ...
details.setServerName( properties.get( [as above] ) );
...
list.add( details );
++i;
}

Open the file using Java IO
Parse the file line by line. Try storing the 'Key' 'value' pairs in a hashMap, you can then iterate over that adding/updating serverDetails that are stored in your arrayList.

Quick example:
private static final String KEY ="server";
public static void main(String[] args) throws IOException {
Properties properties = new Properties();
properties.load(new FileInputStream("props.properties"));
int i = 1;
while (properties.containsKey(KEY + i + ".serverName")) {
String serverName = properties.getProperty(KEY + i + ".serverName");
String serverType = properties.getProperty(KEY + i + ".serverType");
String hostName = properties.getProperty(KEY + i + ".hostName");
String userName = properties.getProperty(KEY + i + ".userName");
String password = properties.getProperty(KEY + i + ".password");
System.out.println(serverName);
System.out.println(serverType);
System.out.println(hostName);
System.out.println(userName);
System.out.println(password);
i++;
}
}
props.properties:
server1.serverName =1
server1.serverType =2
server1.hostName =3
server1.userName =4
server1.password =5
server2.serverName =6
server2.serverType =7
server2.hostName =8
server2.userName =9
server2.password =10

Properties properties = new Properties();
properties.load(new FileInputStream("application.properties"));
int i = 1;
String serverNameKey = "server" + i + ".serverName";
while (properties.containsKey(serverNameKey)) {
String serverName = (String) properties.get(serverNameKey);
//Read other properties
// Create new ServerDetails
// Add to list
i++;
}

Authenticating from Java (Linux) to Active Directory using LDAP WITHOUT servername

Our developers use Java on Linux for various things (like checking membership of groups etc). It works - no problem with that!
The problem is that they have hardcoded the servernames of our Domain Controllers (LDAP-servers) in their code. So now when we need to replace them with newer DCs, they need to change the code.
Active Directory by nature is redundant. The domain name (example: domain.local) is a round-robin of all the DC:s available for our AD.
Is there any way for the developer to NOT specify Domain Controller server names but simply the Active Directory domain name and then their Linux server will find the DC:s available and use whichever one is up and running?
Examples/links appreciated. Thanks!

Obviously, the server name should at least be configurable, not hard coded into the application.
However, you should be able to find the server by looking up a special DNS record, namely a SRV record for _ldap._tcp.DOMAINNAME. The linux servers have to be configured to use the same DNS server as your AD updates.
To determine whether this is feasible, run the command host -t srv _ldap._tcp.DOMAINNAME on your linux server
See also Querying the DNS service records to find the hostname and TCP/IP provides some info on how to look up SRV records in java, and https://community.oracle.com/blogs/kohsuke/2008/06/12/more-active-directory-integration-java
