Hi I m running tests that calls real API calls. I want to make sure the api endpoint returns 200 before I run the tests. I would want to retry couple of times every few mins if it returns 500 or 503. What is the best way to do this in junit. Any pointers appreciated.

I am trying to extend NotNull for additional fieldName so that i could extract the field and have all messages as one custom message for all required fields. I am doing this:
@Retention(RetentionPolicy.RUNTIME) @Target({ ElementType.FIELD }) @Constraint(validatedBy = NotNullFieldValidator.class) @Documented public @interface NotNullField { NotNull superAnnotation(); String fieldName(); } @Component public class NotNullFieldValidator implements ConstraintValidator<NotNullField, String>{ private String fieldName; private NotNull superAnnotation; @Override public void initialize(NotNullField annotation) { this.fieldName = annotation.fieldName(); this.superAnnotation = annotation.superAnnotation(); } @Override public boolean isValid(String value, ConstraintValidatorContext context) { // TODO Auto-generated method stub return false; } At service layer @NotNullField(fieldName = "startDate", superAnnotation = @NotNull(message = "{missing}")) private String startDate

How can i use isValid implementation of NotNull.
I am getting error that the default message is not defined. Will i have to redefine everything

I have this custom message in my ValidationMessage.properties ->
missing.startDate= startDate is a required field.

I have this on my request
@NotNull(message="{missing.startDate}")

Now, this forces me to create a message for each field. If i could do something like this
In ValidationMessage.properties
missing = fieldName is a required field. OR
missing = {0} is a required field.

@NotNull(field="startDate") or just have it as @NotNull

@NotNull is for javax

How can we substitute the field name being validation with {0} when emitting out the message.

I have a use case wherein i have multiple classes and i am trying to annotate all of those classes. I am trying to build a map of all the annotated fields of all the classes at startup with the actual field names so that when a user gives me annotated field name i can map it to actual field names.
So my first start was to create my own annotation class and annotate all the fields of the classes with it providing a name. But how do i build a map and find out all the classes that are annotated with my annotation.

Thanks Mike, this helped. I didn't know about how we could merge two regex patterns.

How will you combine it..this doesn't work
import java.util.regex.Matcher; import java.util.regex.Pattern; public class RegexTester { /** * @param args */ public static void main(String[] args) { Pattern pattern1 = Pattern.compile("eBayAndroid/[2-9].[9](.[1-9])?"); Pattern pattern2 = Pattern.compile("eBayAndroid/[3-9].[1-9](.[1-9])?"); Pattern pattern = Pattern.compile(pattern1.pattern() + pattern2.pattern()); Matcher matcher = pattern.matcher("eBayAndroid/2.9.9"); System.out.println("Input String matches regex - "+matcher.matches()); matcher = pattern.matcher("eBayAndroid/2.9.9"); System.out.println("Input String matches regex - "+matcher.matches()); matcher = pattern.matcher("eBayAndroid/3.1.9"); System.out.println("Input String matches regex - "+matcher.matches()); } }

The starting string is Android/2.9.1
so i tried to do this but it is not printing the right result
public class RegexTester { /** * @param args */ public static void main(String[] args) { Pattern pattern = Pattern.compile("eBayAndroid/[2-9].[9](.[1-9])?"); Matcher matcher = pattern.matcher("eBayAndroid/2.9.9"); System.out.println("Input String matches regex - "+matcher.matches()); //print true matcher = pattern.matcher("eBayAndroid/2.9.9"); System.out.println("Input String matches regex - "+matcher.matches()); //print true matcher = pattern.matcher("eBayAndroid/3.1.9"); System.out.println("Input String matches regex - "+matcher.matches()); //print true matcher = pattern.matcher("eBayAndroid/2.1.9"); System.out.println("Input String matches regex - "+matcher.matches()); //print false } }

Actually the real problem is that the following should match
2.9
2.9.1
2.9.2
and so on
3.1
3.1.1
3.2.1
so from 3 onwards any digit could match
but for ones starting with 2, the only digit allowed next is 9

if i try [2-9][1-9][1-9], in that case 2.1.1 will match, but i want to match the only conditions mentioned in the subject

Hi,

I created a threadsafe async client using a factory.
I create a request builder after that and set header and url.
should i use factory to invoke the boundrequestbuilder, for reference here is the code:
private static BoundRequestBuilder createReqBuilder(JSONObject items) throws Exception { AsyncHttpClient client = AsyncHttpClientFactory.getThreadSafeClient(); AsyncHttpClient.BoundRequestBuilder reqBuilder; reqBuilder = client.preparePost(url); byte[] bytes = compress(items.toString().getBytes()); reqBuilder.setBody(bytes); reqBuilder.setHeader("Connection", "Keep-Alive"); return reqBuilder; }

Here is the code for creating threadsafe async client
private static AsyncHttpClient client; public synchronized static AsyncHttpClient getThreadSafeClient() { if (client != null) return client; AsyncHttpClientConfigBean config = new AsyncHttpClientConfigBean(); config.setConnectionTimeOutInMs(3000); config.setRequestTimeoutInMs(30 * 1000); client = new AsyncHttpClient(config); return client; }

I have a date in this format ->SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm Z");

How can i extract just Z ie. Zone from it, is it possible with stringifying and extracting it.

I have this program

String s = "2013-10-15T11:43 -0700"; DateFormat inFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm Z"); Date date = inFormat.parse(s.trim()); DateFormat outFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm Z"); outFormat.setTimeZone(TimeZone.getTimeZone("America/Denver")); System.out.println(outFormat.format(date)); long milli = date.getTime(); Date mstTime = new Date(milli); System.out.println(milli); System.out.println(outFormat.format(mstTime));

Here i am getting a time with a timezone and the timezone is in UTC, is that a correct assumption
the output is as follows, why is not as per the input
2013-10-15T12:43 -0600
1381862580000
2013-10-15T12:43 -0600
