jar information

Sometimes you need to join jenkins build, git commit with your artifact.
So it is easy to do with

                org.apache.maven.plugins
                maven-ejb-plugin
                2.1
                
                    3.0
                    
                        
                         *****
                            *****
                            ${project.version}
                            *****
                            *****
                            
                            ${BUILD_NUMBER}
                            
                            ${GIT_COMMIT}
                            ${maven.build.timestamp}
                                            
                    
                
            

Git for release management

1. Check your branch is from master to be sure no commits would be missed from previous build
git branch --merged your_branch

git branch --no-merged master

2. Make code review via patch file
git diff master your_branch > diff.patch
Очень удобно проверить через GitExtensions

Junit vs TestNG

1. @BeforeClass в Junit static
2. Неудобное использование @DataProvider
3. Порядок выполнения

Использование @DataProvider в Junit с либой junit-dataprovider

junit

junit 1.4.12 test

com.tngtech.java
junit-dataprovider 1.9.2 test

@RunWith(DataProviderRunner.class)
public class DataProviderTest {

    @DataProvider
    public static Object[][] dataProviderAdd() {
        return new Object[][] {
                { 0, 0, 0 },
                { 1, 1, 2 },
        };
    }

    @Test
    @UseDataProvider("dataProviderAdd")
    public void testAdd(int a, int b, int expected) {
        int result = a + b;
        assertEquals(expected, result);
    }
}

Multiple readers from JMS topic on Websphere MQ

If I were to do this in WebSphere MQ the solution would be to create an administrative subscription which would result in a single copy of each message on the given topic to be placed onto a queue. Then your multiple subscribers could compete for messages on that queue. 

This way your app could have multiple threads among which the messages are distributed, and at the same time other subscribers independent of this application could dynamically (un)subscribe to the same topic.
