I am using Jacob to find out the MAC addresses of all access points that are detected by my wireless NIC.
According to WMI documentation Ndis80211BSSIList is: "The list of in-range BSSIDs and their properties". As far as I can understand it returns an array of objects of the Class MSNdis_80211_WLanBssId, that each of them has some properties.
My question is how I can access these properties of each of these instances (each instance is a different BSSID with properties such as MAC Address or SSID). Any help would be valuable.
public class testWMIJacob {
public static void main(String[] args) {
String host = "localhost";
String connectStr = String.format("winmgmts:\\\\%s\\root\\wmi", host);
String query = "SELECT * FROM MSNdis_80211_BSSIList ";
ActiveXComponent axWMI = new ActiveXComponent(connectStr);
Variant vCollection = axWMI.invoke("ExecQuery", new Variant(query));
EnumVariant enumVariant = new EnumVariant(vCollection.toDispatch());
Dispatch item = null;
while (enumVariant.hasMoreElements()) {
item = enumVariant.nextElement().toDispatch();
String req = Dispatch.call(item,"Ndis80211BSSIList").toString();
}
}
}

I want to make an insert operation in an import set table through the web service from ServiceNow with axis2 version 1.6.4
I used wsdl2java with the wsdl file to create classes in my java project.
After it, i created a new class Request on which i would build my soap request to the webservice.
I believe I have 2 (might be more) major problems:
Unserstanding the difference between a stub and a proxy, respectively, the classes ServiceNowSoapStub and ServiceNowSoapProxy and what is the purpose of each of them.
The existing insert method needs a lot of arguments and i wish to make inserts with a selected number of arguments. do i need to add that specific insert method to the architecture?
Here is what I have:
public class Request {
public static void main(String[] args) throws RemoteException {
try{
HttpTransportProperties.Authenticator basicAuthentication = new HttpTransportProperties.Authenticator();
basicAuthentication.setUsername("xxxx");
basicAuthentication.setPassword("xxxx");
ServiceNowSoapStub proxy = new ServiceNowSoapStub();
proxy._setProperty(org.apache.axis2.transport.http.HTTPConstants.CHUNKED, Boolean.FALSE);
proxy._setProperty(org.apache.axis2.transport.http.HTTPConstants.AUTHENTICATE, basicAuthentication);
BigDecimal actuals = new BigDecimal("0.04");
BigInteger appId = new BigInteger("3495766");
String appNonApp = "ApNon";
BigInteger productId = new BigInteger("704217");
BigInteger serviceId = new BigInteger("1537");
String serviceName = "IT";
String bpName = "BNK-RSK";
String method = "N";
String bsCode = "ITDV";
String customerCostCode = "30973250";
String customerCountry = "US";
String customerGroup = "Wealth";
String customerLegalEntity = "HB";
String dsId = "EU56";
BigInteger supplierCostCode = new BigInteger("675136");
String supplierCountry = "UK";
String supplierLegalEntity = "BR";
BigInteger total = new BigInteger ("411");
ServiceNowSoapProxy request = new ServiceNowSoapProxy("https://dev34363.service-now.com/u_it_actuals_import_set");
request.insertTest(actuals, appId, appNonApp, productId, serviceId, serviceName, bpName, method, bsCode, customerCostCode,
customerCountry, customerGroup, customerLegalEntity, dsId, supplierCostCode, supplierCountry, supplierLegalEntity, total);
} catch (org.apache.axis.AxisFault e) {
e.printStackTrace();
}
}
}
What am I doing wrong? or can please anyone refer me to some helpful link?
The wiki page of servicenow addressing this subject is a bit out of date so i can't solve my problem through it.
Thanks!
I found this post about BitPay but it's not very clear how I can use it.
https://help.bitpay.com/development/how-do-i-use-the-bitpay-java-client-library
I implemented this code:
public void createInvoice() throws BitPayException
{
ECKey key = KeyUtils.createEcKey();
BitPay bitpay = new BitPay(key);
InvoiceBuyer buyer = new InvoiceBuyer();
buyer.setName("Satoshi");
buyer.setEmail("satoshi#bitpay.com");
Invoice invoice = new Invoice(100.0, "USD");
invoice.setBuyer(buyer);
invoice.setFullNotifications(true);
invoice.setNotificationEmail("satoshi#bitpay.com");
invoice.setPosData("ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890");
Invoice createInvoice = bitpay.createInvoice(invoice);
}
How should I implement the private key?
That answer, I believe, is found in the following file: https://github.com/bitpay/java-bitpay-client/blob/master/src/main/java/controller/BitPay.java - that is to say, you would set your private key on the BitPay client instance. There you can find the appropriate constructor for your needs. You will want to use one or more of the following fields depending on your specific needs:
private ECKey _ecKey = null;
private String _identity = "";
private String _clientName = "";
private Hashtable<String, String> _tokenCache;
Edit: encryption and decryption of your private key exists here: https://github.com/bitpay/java-bitpay-client/blob/master/src/main/java/controller/KeyUtils.java
If, for instance, you used the following constructor:
public BitPay(URI privateKey) throws BitPayException, URISyntaxException, IOException {
this(KeyUtils.loadEcKey(privateKey), BITPAY_PLUGIN_INFO, BITPAY_URL);
}
You would pass in the URI for your private key.
Specific instructions on this available here: https://github.com/bitpay/java-bitpay-client/blob/master/GUIDE.md
Two very simple examples:
BitPay bitpay = new BitPay();
ECKey key = KeyUtils.createEcKey();
this.bitpay = new BitPay(key);
Number two:
// Create the private key external to the SDK, store it in a file, and inject the private key into the SDK.
String privateKey = KeyUtils.getKeyStringFromFile(privateKeyFile);
ECKey key = KeyUtils.createEcKeyFromHexString(privateKey);
this.bitpay = new BitPay(key);
After implementing the private key, you'd till need to initialize the client and connect to the server.
Uses on-line decomentation I come up with the following code to terminate the current EC2 Instance:
public class Ec2Utility {
static private final String LOCAL_META_DATA_ENDPOINT = "http://169.254.169.254/latest/meta-data/";
static private final String LOCAL_INSTANCE_ID_SERVICE = "instance-id";
static public void terminateMe() throws Exception {
TerminateInstancesRequest terminateRequest = new TerminateInstancesRequest().withInstanceIds(getInstanceId());
AmazonEC2 ec2 = new AmazonEC2Client();
ec2.terminateInstances(terminateRequest);
}
static public String getInstanceId() throws Exception {
//SimpleRestClient, is an internal wrapper on http client.
SimpleRestClient client = new SimpleRestClient(LOCAL_META_DATA_ENDPOINT);
HttpResponse response = client.makeRequest(METHOD.GET, LOCAL_INSTANCE_ID_SERVICE);
return IOUtils.toString(response.getEntity().getContent(), "UTF-8");
}
}
My issue is that my EC2 instance is under an AutoScalingGroup which is under a CloudFormationStack, that is because of my organisation deployment standards though this single EC2 is all there is there for this feature.
So, I want to terminate the entire CloudFormationStack from the JavaSDK, keep in mind, I don't have the CloudFormation Stack Name in advance as I didn't have the EC2 Instance Id so I will have to get it from the code using the API calls.
How can I do that, if I can do it?
you should be able to use the deleteStack method from cloud formation sdk
DeleteStackRequest request = new DeleteStackRequest();
request.setStackName(<stack_name_to_be_deleted>);
AmazonCloudFormationClient client = new AmazonCloudFormationClient (<credentials>);
client.deleteStack(request);
If you don't have the stack name, you should be able to retrieve from the Tag of your instance
DescribeInstancesRequest request =new DescribeInstancesRequest();
request.setInstanceIds(instancesList);
DescribeInstancesResult disresult = ec2.describeInstances(request);
List <Reservation> list = disresult.getReservations();
for (Reservation res:list){
List <Instance> instancelist = res.getInstances();
for (Instance instance:instancelist){
List <Tag> tags = instance.getTags();
for (Tag tag:tags){
if (tag.getKey().equals("aws:cloudformation:stack-name")) {
tag.getValue(); // name of the stack
}
}
At the end I've achieved the desired behaviour using the set of the following util functions I wrote:
/**
* Delete the CloudFormationStack with the given name.
*
* #param stackName
* #throws Exception
*/
static public void deleteCloudFormationStack(String stackName) throws Exception {
AmazonCloudFormationClient client = new AmazonCloudFormationClient();
DeleteStackRequest deleteStackRequest = new DeleteStackRequest().withStackName("");
client.deleteStack(deleteStackRequest);
}
static public String getCloudFormationStackName() throws Exception {
AmazonEC2 ec2 = new AmazonEC2Client();
String instanceId = getInstanceId();
List<Tag> tags = getEc2Tags(ec2, instanceId);
for (Tag t : tags) {
if (t.getKey().equalsIgnoreCase(TAG_KEY_STACK_NAME)) {
return t.getValue();
}
}
throw new Exception("Couldn't find stack name for instanceId:" + instanceId);
}
static private List<Tag> getEc2Tags(AmazonEC2 ec2, String instanceId) throws Exception {
DescribeInstancesRequest describeInstancesRequest = new DescribeInstancesRequest().withInstanceIds(instanceId);
DescribeInstancesResult describeInstances = ec2.describeInstances(describeInstancesRequest);
List<Reservation> reservations = describeInstances.getReservations();
if (reservations.isEmpty()) {
throw new Exception("DescribeInstances didn't returned reservation for instanceId:" + instanceId);
}
List<Instance> instances = reservations.get(0).getInstances();
if (instances.isEmpty()) {
throw new Exception("DescribeInstances didn't returned instance for instanceId:" + instanceId);
}
return instances.get(0).getTags();
}

I am using JClouds-Chef to:
Bootstrap a newly-provisioned Linux VM; and then
Run the chef-client on that node to configure it
It's important to note that all I'm currently configuring Chef with is a role (that's all it needs; everything else is set up on the Chef server for me):
public class ChefClient {
public configure() {
String vmIp = "myapp01.example.com";
String vmSshUsername = "myuser";
String vmSshPassword = "12345";
String endpoint = "https://mychefserver.example.com";
String client = "myuser";
String validator = "chef-validator";
String clientCredential = Files.toString(new File("C:\\Users\\myuser\\sandbox\\chef\\myuser.pem"), Charsets.UTF_8);
String validatorCredential = Files.toString(new File("C:\\Users\\myuser\\sandbox\\chef\\chef-validator.pem"), Charsets.UTF_8);
Properties props = new Properties();
props.put(ChefProperties.CHEF_VALIDATOR_NAME, validator);
props.put(ChefProperties.CHEF_VALIDATOR_CREDENTIAL, validatorCredential);
props.put(Constants.PROPERTY_RELAX_HOSTNAME, "true");
props.put(Constants.PROPERTY_TRUST_ALL_CERTS, "true");
ChefContext ctx = ContextBuilder.newBuilder("chef")
.endpoint(endpoint)
.credentials(client, clientCredential)
.overrides(props)
.modules(ImmutableSet.of(new SshjSshClientModule())) //
.buildView(ChefContext.class);
ChefService chef = ctx.getChefService();
List<String> runlist = new RunListBuilder().addRole("platformcontrol_dev").build();
ArrayList<String> runList2 = new ArrayList<String>();
for(String item : runlist) {
runList2.add(item);
}
BootstrapConfig bootstrapConfig = BootstrapConfig.builder().runList(runList2).build();
chef.updateBootstrapConfigForGroup("jclouds-chef", bootstrapConfig);
Statement bootstrap = chef.createBootstrapScriptForGroup("jclouds-chef");
SshClient.Factory sshFactory = ctx.unwrap().utils()
.injector().getInstance(Key.get(new TypeLiteral<SshClient.Factory>() {}));
SshClient ssh = sshFactory.create(HostAndPort.fromParts(vmIp, 22),
LoginCredentials.builder().user(vmSshUsername).password(vmSshPassword).build());
ssh.connect();
try {
StringBuilder rawScript = new StringBuilder();
Map<String, String> resolvedFunctions = ScriptBuilder.resolveFunctionDependenciesForStatements(
new HashMap<String, String>(), ImmutableSet.of(bootstrap), OsFamily.UNIX);
ScriptBuilder.writeFunctions(resolvedFunctions, OsFamily.UNIX, rawScript);
rawScript.append(bootstrap.render(OsFamily.UNIX));
ssh.put("/tmp/chef-bootstrap.sh", rawScript.toString());
ExecResponse result = ssh.exec("bash /tmp/chef-bootstrap.sh");
} catch(Throwable t) {
println "Exception: " + t.message
} finally {
ssh.disconnect();
}
}
}
Our in-house "Chef" (our devops guy) now wants to add the concept of Chef "environments" to all our recipes in addition to the existing roles. This is so that we can specify environment-specific roles for each node. My question: does the JClouds-Chef API handle environments? If so, how might I modify the code to incorporate environment-specific roles?
Is it just as simple as:
BootstrapConfig bootstrapConfig = BootstrapConfig.builder()
.environment("name-of-env-here?").runList(runList2).build();
Yes, it is that simple. That will tell the bootstrap script to register the node in the specified environment.
Take into account, though, that the environment must already exist in the Chef Server. If you want to create nodes in new environments, you can also create them programmatically as follows:
ChefApi api = ctx.unwrapApi(ChefApi.class);
if (api.getEnvironment("environment-name") == null) {
Environment env = Environment.builder()
.name("environment-name")
.description("Some description")
.build();
api.createEnvironment(env);
}
I am writing simple client application to connect to weblogic and list all the libraries that a webapp is depending on.However, I am having difficulty in finding the right attributes for a objectname. For example,
If you look at the below sample code given on oracle.com to connect MBeanServer
public static void initConnection(String hostname, String portString,
String username, String password) throws IOException,
MalformedURLException {
String protocol = "t3";
Integer portInteger = Integer.valueOf(portString);
int port = portInteger.intValue();
String jndiroot = "/jndi/";
String mserver = "weblogic.management.mbeanservers.edit";
JMXServiceURL serviceURL = new JMXServiceURL(protocol, hostname, port,
jndiroot + mserver);
Hashtable h = new Hashtable();
h.put(Context.SECURITY_PRINCIPAL, username);
h.put(Context.SECURITY_CREDENTIALS, password);
h.put(JMXConnectorFactory.PROTOCOL_PROVIDER_PACKAGES,
"weblogic.management.remote");
connector = JMXConnectorFactory.connect(serviceURL, h);
connection = connector.getMBeanServerConnection();
}
public ObjectName startEditSession() throws Exception {
// Get the object name for ConfigurationManagerMBean.
ObjectName cfgMgr = (ObjectName) connection.getAttribute(service,
"ConfigurationManager");
// Instruct MBeanServerConnection to invoke
// ConfigurationManager.startEdit(int waitTime int timeout).
// The startEdit operation returns a handle to DomainMBean, which is
// the root of the edit hierarchy.
ObjectName domainConfigRoot = (ObjectName)
connection.invoke(cfgMgr,"startEdit",
new Object[] { new Integer(60000),
new Integer(120000) }, new String[] { "java.lang.Integer",
"java.lang.Integer" });
if (domainConfigRoot == null) {
// Couldn't get the lock
throw new Exception("Somebody else is editing already");
}
return domainConfigRoot;
}
The line
ObjectName cfgMgr = (ObjectName) connection.getAttribute(service,
"ConfigurationManager");
Is referring to a JMX attribute ConfigurationManger. How can we find all the attributes that are under a given objectname in weblogic?
Thanks for your help!!
Nevermind! I found the solution.
You get attributes for a ObjectName by calling getBeanInfo on the ServerConnection!
Example:
MBeanAttributeInfo[] beanInfo = (connection.getMBeanInfo(objectName)).getAttributes();
for(MBeanAttributeInfo info:beanInfo)
System.out.println(info.getType()+" "+info.getName());
Maybe the WebLogic Classloader Analysis Tool (CAT) can give additional insight out of the box ...
