Can we use Google data plugin in scala? - java

I am new to scala. I am trying to import contacts from gmail in to my application.I can create sample application in java using Eclipse by following link https://developers.google.com/google-apps/contacts/v2/developers_guide_java?csw=1#retrieving_without_query
I can Import the contacts in My java application.And It works fine. My java code is
import com.google.gdata.client.contacts.ContactsService;
import com.google.gdata.data.contacts.ContactEntry;
import com.google.gdata.data.contacts.ContactFeed;
import com.google.gdata.model.gd.Email;
import com.google.gdata.util.AuthenticationException;
import com.google.gdata.util.ServiceException;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import java.util.List;
/**
* This is a test template
*/
public class Contacts {
public static void main(String[] args) {
try {
// Create a new Contacts service
System.out.println("hiiii"+args[0]);
ContactsService myService = new ContactsService("My Application");
myService.setUserCredentials(args[0],args[1]);
// Get a list of all entries
URL metafeedUrl = new URL("http://www.google.com/m8/feeds/contacts/"+args[0]+"#gmail.com/base");
System.out.println("Getting Contacts entries...\n");
ContactFeed resultFeed = myService.getFeed(metafeedUrl, ContactFeed.class);
List<ContactEntry> entries = resultFeed.getEntries();
for(int i=0; i<entries.size(); i++) {
ContactEntry entry = entries.get(i);
System.out.println("\t" + entry.getTitle().getPlainText());
System.out.println("\t" + entry.getEmailAddresses());
for(com.google.gdata.data.extensions.Email emi:entry.getEmailAddresses())
System.out.println(emi.getAddress());
}
System.out.println("\nTotal Entries: "+entries.size());
}
catch(AuthenticationException e) {
e.printStackTrace();
System.out.println("Authentication failed");
}
catch(MalformedURLException e) {
e.printStackTrace();
System.out.println("url");
}
catch(ServiceException e) {
e.printStackTrace();
System.out.println("Service exc");
}
catch(IOException e) {
e.printStackTrace();
System.out.println("IO exception");
}
}
}
I tried to use same library functions for My Scala but it doesn't work. My Scala code is
import com.google.gdata.client.contacts.ContactsService
import com.google.gdata.data.contacts.ContactEntry
import com.google.gdata.data.contacts.ContactFeed
import com.google.gdata.util.ServiceException
import com.google.gdata.util.AuthenticationException
import java.io.IOException
import java.net.URL
import java.net.MalformedURLException
object Contacts {
class Test
{
def main(args:Array[String])
{
println("hiii")
try {
// Create a new Contacts service
//ContactsService myService = new ContactsService("My Application");
//myService.setUserCredentials(args[0],args[1]);
val myService= new ContactsService("My App")
myService.setUserCredentials("MyemailId","password")
val metafeedUrl = new URL("http://www.google.com/m8/feeds/contacts/"+"MyemailId"+"#gmail.com/base")
val resultFeed = myService.getFeed(metafeedUrl, classOf[ContactFeed])
//List<ContactEntry> entries = resultFeed.getEntries();
val entries = resultFeed.getEntries();
for(i <-0 to entries.size())
{
var entry=entries.get(i)
println(entry.getTitle().getPlainText())
}
}
catch{
case e:AuthenticationException=>{
e.printStackTrace();
}
case e:MalformedURLException=>{
e.printStackTrace();
}
case e:ServiceException=>{
e.printStackTrace();
}
case e:IOException=>
{
e.printStackTrace();
}
}
}
}
}
But it does not works. Can I use java library in Scala?


The problem that's causing your error, is that the object Contacts does not have a main method. Instead, it contains an inner class called Test which has a main method. I don't believe that is what you want (in Scala, object methods are the equivalent of Java static methods), so the main method should be moved out into Contacts, and the inner class deleted.
Also, for(i <-0 to entries.size()) is probably a mistake. This is roughly equivalent to for(int i=0; i<=entries.size(); i++) (notice the <=). You probably want for(i <-0 until entries.size()).
While you're there, you can kill the try..catch blocks if you like, as Scala doesn't use checked exceptions. If you import scala.collection.JavaConversions._, then you can use for (entry <- entries), which may be less error prone.
If it still doesn't work (or when posting future questions), provide as much info as you can (error messages, warnings, etc.), as it makes it far more likely that someone will be able to help.

UTGARD opc client: Read multiple items repeatedly

I have written the following code using the Utgard OPC library.
I need to read data from an OPC server once every 15 seconds. However, I'm not sure if this is the most optimal way to implement it. In my scenario I require to read upward of 300 tags from the server.
Any suggestions?

I'm not sure you need to add the items over and over again in your while group.
In other libraries (.net or native c++) usually you need to add the items only once, and the callback called whenever the value of the item is changed.
In .net or c++ we get a global callback per group, which seems more effective than individual callbacks per items. Maybe SyncAccess has some global callback, look for it.
So the possible optimizations:
remove the while part, add items only once and sleep the thread infinite.
look for global callback for all items

You should create a subscription in this case.

The code shows valid when the data has been taken from examples and invalid when the data comes from paypal web site.
I wonder why this cannot be validated. Any help is welcome.

You may want to test the validation with actual sandbox transactions and webhook events. Simulator mock data may not be updated with the sandbox algorithm, and is recommended for testing URL accessibility of your script.

Exception thrown when trying to load Pentaho report through java program

Extracting data from HTML table with Jsoup

I am trying to extract the data from the table on the following website. I.e Club, venue, start time. http://www.national-autograss.co.uk/february.htm
I have got many examples on here working that use a css class table but this website doesn't. I have made an attempt with the code below but it doesn't seem to provide any output. Any help would be very much appreciated.
import java.io.IOException;
import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
import org.jsoup.select.Elements;
public class Main {
public static void main(String[] args) {
Document doc = null;
try {
doc = Jsoup.connect("http://www.national-autograss.co.uk/february.htm").get();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Elements elements = doc.select("table#table1");
String name;
for( Element element : elements )
{
name = element.text();
System.out.println(name);
}
}
}

An id should be unique, so you should use directly doc.select("#table1") and so on

Using reflections with onejar plugin

I am using reflections with onejar maven plugin, and I have a problem when running the resulting jar:
20204 [main] ERROR org.reflections.Reflections - given scan urls are
empty. set urls in the configuration
It seems to me that reflections doesn't support the class loader that onejar is using. I've been using the following configuration of Reflections in my code:
Reflections reflections = new Reflections("path.to.my.package");
Any ideas? Thanks.

Yep a known issue. There is a work around...
