I was wondering why my file is not updating to dropbox. Currently it only creates the an empty file.
final String TEST_FILE_NAME = DateTime + ".txt";
DbxPath path = new DbxPath(DbxPath.ROOT, TEST_FILE_NAME);
try {
if (!FileSystem.exists(path)) {
newFile = FileSystem.create(path);
try {
newFile.writeString("Hello world!");
} finally {
newFile.update();
newFile.close();
}
}
} catch (DbxException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
Solved: I never unlinked my dbxacc and kept relinking, causing errors to show up! Silly mistake.

Could someone please help what changes need to be done to get the desired output result
I'm trying to access the messaging metrics provided by Cassandra from Java using JMX. I get the correct results when I use the following query with swiss java knife
java -jar sjk-plus-0.4.2.jar mx -s localhost:7100 -mg -all -b org.apache.cassandra.metrics:type=Messaging,name=* -f Mean
org.apache.cassandra.metrics:type=Messaging,name=CrossNodeLatency
1331.0469921040174
org.apache.cassandra.metrics:type=Messaging,name=datacenter1-Latency
1331.1071897694487
However, with the following Java code I get a javax.management.InstanceNotFoundException: org.apache.cassandra.metrics:type=Messaging exception.
JMXServiceURL url = null;
try {
url = new JMXServiceURL("service:jmx:rmi:///jndi/rmi://127.0.0.1:7100/jmxrmi");
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JMXConnector mConnector = null;
try {
mConnector = JMXConnectorFactory.connect(url);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
MBeanServerConnection mMBSC = null;
try {
mMBSC = mConnector.getMBeanServerConnection();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
ObjectName mObjectName = null;
try {
mObjectName = new ObjectName("org.apache.cassandra.metrics:type=Messaging");
} catch (MalformedObjectNameException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Set<ObjectName> myMbean = null;
try {
myMbean = mMBSC.queryNames(mObjectName, null);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
System.out.println((mMBSC.getAttribute(mObjectName, "*")).toString());
} catch (AttributeNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InstanceNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (MBeanException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (ReflectionException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Could someone please explain where am I making a mistake?
Swiss Java Knife seems to accept an ObjectName wildcard (or pattern) as:
org.apache.cassandra.metrics:type=Messaging,name=*
but your code is simply looking up a non-pattern MBean as:
org.apache.cassandra.metrics:type=Messaging
Change your code to:
Use the pattern
queryNames will return a Set of matching ObjectNames, so iterate through the set and query each one.
You need to specify a string array of actual MBean attribute names, not "*" as in your code. (It would be nice if that was supported)
Something like:
mObjectName = new ObjectName("org.apache.cassandra.metrics:type=Messaging,name=*");
Set<ObjectName> names = mMBSC.queryNames(mObjectName, null);
for(ObjectName on: names) {
System.out.println(on + "\n" + mMBSC.getAttribute(on, "Mean").toString());
}
I want to find out differences between two revisions using org-netbeans-lib-cvsclient-RELEASE712.jar.
any working example?
DiffCommand diffCommand = new DiffCommand();
diffCommand.setRecursive(true);
diffCommand.setRevision1("rel-2230");
diffCommand.setRevision2("rel-2240");
diffCommand.setFiles(new File[]{new File("D:/test/")});
diffCommand.setBuilder(new SimpleDiffBuilder(em, diffCommand));
try {
System.out.println(diffCommand.getCVSCommand());
cvsClient.executeCommand(diffCommand, opts);
Set files = cvsClient.getAllFiles(new File("D:/test/"));
} catch (CommandException | AuthenticationException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();

I am trying to use java to open an exe file. I'm not sure which program I want to open so I am using Skype as an example. When I try to do it, it gives me errors.
try {
Process p = Runtime.getRuntime().exec("C:\\Program Files (x86)\\Skype\\Phone\\Skype");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
error:
Cannot run program "C:\Program": CreateProcess error=2, The system cannot find the file specified
Try this:
String path = "/path/to/my_app.exe";
File file = new File(path);
if (! file.exists()) {
throw new IllegalArgumentException("The file " + path + " does not exist");
}
Process p = Runtime.getRuntime().exec(file.getAbsolutePath());
You have to use a string array, change to
try {
Process p = Runtime.getRuntime().exec(new String[] {"C:\\Program Files (x86)\\Notepad++\\notepad++.exe"});
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
You are on windows so you have to include the extension .exe
try {
Process p = Runtime.getRuntime().exec("C:/Program Files (x86)/Skype/Phone/Skype.exe");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Maybe use File.separator instead of '\'
I tried this and it works fine, it's taken from your example. Pay attention to the double \\
public static void main(String[] args) {
try {
Process p;
p = Runtime.getRuntime().exec("C:\\Program Files\\Java\\jdk1.8.0_05\\bin\\Jconsole.exe");
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
i'm using this code:
if(!facebook.isSessionValid()) {
try {
String jsonUser = facebook.request("me");
obj = Util.parseJson(jsonUser);
String id = obj.optString("id");
String name = obj.optString("name");
tv1.setText("sodfnsdf");
} catch (MalformedURLException e) {
tv1.setText("1");
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
tv1.setText("2");
// TODO Auto-generated catch block
e.printStackTrace();
} catch (FacebookError e) {
tv1.setText("3");
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
tv1.setText("4");
// TODO Auto-generated catch block
e.printStackTrace();
}
}
else {
tv1.setText("Error");
}
i've searched online and in stackoverflow, but cannot find the answer to my question, i only found very similiar questions but different in some ways..
Hey you need to call facebook.authorize method
if(!facebook.isSessionValid()) {
facebook.authorize() }
For more information you can refer this link. I think it will help you.
