Useful linux commands

1. List the JAVA processes running on linux:

          ps -ef | grep java | awk '{print $2 " " $8}'

     Result:

           2070 /opt/Portal61/WebSphere/AppServer/java/bin/java
           7440 /opt/IBM/WebSphere/AppServer61/java/bin/java

Open windows share folder on linux

2011-02-16T16:13:00.013+05:30

Mount:

mount -t cifs -o username=jp, password=jp //192.168.183.1/doc /home/prakash/doc

Unmount:

umount -f /home/prakash/doc

WinSCP is the best tool that is used to transfer the data between windows and linux. But if we consider the transfer rate it will take much time to transfer, so, as you consider transfer rate windows share is the best one.

How to get cobertura coverage report for *VO.java files

2011-02-15T17:44:00.000+05:30

In some scenario where we want to take coverage report for *VO.java files which has only setters and getters. We might have tried with mvn cobertura:cobertura command where we ever getting coverage for other java files not for VO.java files.

Workaround:

Default behavior of exclusion file type is **/*VO.class.

Solution:

<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.2</version>

<configuration>
    <instrumentation>
        <includes>
            <include>**/*VO.class</include>
        </includes>

        <excludes>
            <exclude>**/*Test.class</exclude>
        </excludes>
    </instrumentation>
</configuration>
</plugin>

mvn compile -Doutput.directory=target/classes cobertura:instrument install -Dwas-ejb

Useful mvn commands

2009-05-27T15:18:00.001+05:30

mvn eclipse:eclipse -DdownloadSources=true

This will set up the eclipse environment and also download the source for the jar files.

mvn clean install war:inplace

This will create a open war inside the target directory. This is very useful to modify non-java resources.

mvn clean install -Dmaven.test.skip=true

This will skip the unit tests . It helps to speed up the install but it is a bad practice.

mvn clean compile install -Dwas-ejb

This will create stub and skeleton for EJB projects.

mvn clean compile install -Dwas6.wasHome="D:\My-Projects\Pack-group\runtimes\base_v61

This will help to deploy EJB projects into WAS.
