Skip execution of method in specific time of day

/* this test fails if the current time is between 12:00am and 3:00am*/

Calendar now = Calendar.getInstance();
int hour = now.get(Calendar.HOUR_OF_DAY);
String timeCheck = "Current time not between 12:00am and 3:00am";
String timeDescription = "Current time" + ((hour < 3) ? "" : " not") + " between 12:00am and 3:00am";
Assume.assumeThat(timeDescription, equalTo(timeCheck));

Assume is package org.junit;(public class Assume )

ANTLR

Today i worked with some text character parsing. In our project, they have used ANTLR parser. ANTLR, ANother Tool for Language Recognition, is a language tool that provides a framework for constructing recognizers, interpreters, compilers, and translators from grammatical descriptions containing actions in a variety of target languages. ANTLR provides excellent support for tree construction, tree walking, translation, error recovery, and error reporting.

http://www.antlr.org/

We have used both Class LLkParser and Class Parser.Alos one important interface that provides is Interface AST in antlr.collections.

Payment gateway

A payment gateway is an e-commerce application service provider service that authorizes payments for e-businesses, online retailers, bricks and clicks, or traditional brick and mortar. Paypal and SecurePay are two common payment gateways. Following are the list of gateways.

In our project we use saferpay payment gateway. In billing-services.xml,
< bean id="billing.paymentService"
class="com.fastsearch.admomentum.billing.service.DefaultPaymentService">
. . .
< !-- this bean is defined in fast-admomentum-paymentgateway.jar -->
< property name="paymentGateway" ref="saferpayPaymentGateway" />
. . .
< /bean>

and in base-configuration.properties, there are lots of configurations.
one of them are,

# The merchant account id with Saferpay
com.fastsearch.admomentum.paymentgateway.saferpay.accountId=XXXXX-XXXXXXXXX

Java Unit testing

This is a simple test class i wrote to test following method.

package com.fastsearch.admomentum.common.time;

import java.io.Serializable;
import java.util.Calendar;
........

public class DateRange implements Serializable {

.....

public boolean isBetween(Calendar date) {
if (getEnd() != null) {
return (date.after(getStart()) && date.before(getEnd()))
|| date.equals(getStart()) || date.equals(getEnd());
} else {
return date.after(getStart()) || date.equals(getStart());
}
}
}

----------------------------------------------

package com.fastsearch.admomentum.common.time;

import junit.framework.TestCase;
import java.util.Calendar;


public class DateRangeUnitTest extends TestCase {

private DateRange dateRange;

public void testIsBetween()
{
assertFalse(isBetweenOutOfBoundTest());
}

private boolean isBetweenOutOfBoundTest()
{
Calendar testDate = Calendar.getInstance();
testDate.clear();
testDate.set(Calendar.YEAR,2007);
testDate.set(Calendar.MONTH,4);
testDate.set(Calendar.DATE,1);

Calendar startDate = Calendar.getInstance();
startDate.clear();
startDate.set(Calendar.YEAR,2007);
startDate.set(Calendar.MONTH,5);
startDate.set(Calendar.DATE,1);

Calendar endDate = Calendar.getInstance();
endDate.clear();
endDate.set(Calendar.YEAR,2007);
endDate.set(Calendar.MONTH,7);
endDate.set(Calendar.DATE,1);

dateRange = new DateRange(startDate, endDate);
return dateRange.isBetween(testDate);
}
}

Cargo

Cargo is a thin wrapper around existing containers (e.g. J2EE containers). It provides different APIs to easily manipulate containers.

Cargo provides the following APIs:

* A Java API to start/stop/configure Java Containers and deploy modules into them. Also Ant tasks, Maven 1, Maven 2 plugins. Intellij IDEA and Netbeans plugins are offered.
* A Java API to parse/create/merge J2EE Modules

Following are some containers.

* Geronimo 1.x
* JBoss 3.x
* JBoss 4.x
* Jetty 4.x
* Jetty 5.x
* Jetty 6.x
* jo 1.x
* Oc4J 9.x
* Orion 1.x
* Orion 2.x
* Resin 2.x
* Resin 3.x
* Tomcat 3.x
* Tomcat 4.x
* Tomcat 5.x
* WebLogic 8.x
