In this post under JMS I will explain how to receive messages asynchronously. Note: I will be using JMS 2.0 api for this and future examples. In all my previous post’s examples I have used “receive” method under “JSMConsumer” class to receive messages synchronously. To receive messages asynchronously we will take the help of “javax.jms.MessageListener”…… Continue reading Receiving JMS messages asynchronously
In this post, I will explain how to send JMS messages asynchronously. Note: I will be using JMS 2.0 api for this and future examples. When messages are sent asynchronously, the producer of the message won’t wait for acknowledgement from the provider. In this case, the producer uses callback approach so that he can be…… Continue reading Sending JMS messages asynchronously
In my previous posts under Spring Batch, I explained with example how to use built in out of the box skip policies. In this post I will explain how to create our own custom skip policy and use it. To create our own custom skip policy we need to implement the interface org.springframework.batch.core.step.skip.SkipPolicy as shown…… Continue reading Implementing Custom Skip Policy
In this post under JMS I will explain how to create temporary queue or topic. Note: I will be using JMS 2.0 api for this and future examples Non temporary queue or topics are created by administrator and we developers connect to those topic or queue using the below method Destination destination = (Destination)initialContext.lookup(“MyQueue”); Whereas…… Continue reading Creating a temporary queue or topic
In this post under JMS I will explain how to send and receive Java Map data as JMS Message payload. Note: I will be using JMS 2.0 api for this and future examples Below is the complete main class code Main Class 1 package package3; 2 3 import java.util.Properties; 4 5 import javax.jms.ConnectionFactory; 6 import…… Continue reading Sending and Receiving Map data as JMS message payload
In this post under Spring Batch, I will explain how to change skip policy to one of out of the box provided skip policies. Whenever we use the “skip-limit” attribute and “skippable-exception-classes” element as shown below at line 4 and 5 1 <batch:job id=”importEmployees”> 2 <batch:step id=”readWriteEmployees”> 3 <batch:tasklet> 4 <batch:chunk reader=”reader” writer=”writer” commit-interval=”50″ skip-limit=”200″>…… Continue reading Changing Skip Policy to out of box provided skip policies

In this post under YamlBeans, I will explain with example how to change default configurations specific to YamlWriter. We take the help of YamlConfig.WriteConfig class. It is a inner static class. It has getters and setters that can be used to change default configurations specific to YamlWriter. For this example, we will use the below…… Continue reading Changing default configurations specific to YamlWriter
In this post under YamlBeans, I will explain with example how to change default configurations specific to YamlReader. We take the help of YamlConfig.ReadConfig class. It is a inner static class. It has getters and setters that can be used to change default configurations specific to YamlReader. For this example, we will use the below…… Continue reading Changing default configurations specific to YamlReader
In this post under YamlBeans, I will explain with example how to change default configurations common to both YamlWriter and YamlReader. The YamlConfig class has getter and setters that can be used to change default configurations. For this example, we will use the below Employee1 class structure. Employee1 class import java.util.List; public class Employee1 {…… Continue reading Changing default configurations common to both YamlWriter and YamlReader
