How to configure the username on git

How to configure the user name on git.

 

This is simple solution but BIG question .....???

To change/configure the user name at your local machine is very easy, but the user name issue is often trouble to developer.

Usually you will get the below error :-

remote: refs/heads/bugfix/testtagging: bd04a65ec413cecbd11cadc336cb4dd25fa3d935: expected committer name 'Manoj Kumar Bardhan' but found 'manojkumar.bardhan'

To fix this , you need to configure the user name as expected. First check what is the existing user name before set to new.

dev@jdg-developer-desktop ~/testtagging/test $ git config --global user.name
manojkumar.bardhan

Change/Configure the user name by using below command, you can provide your expected user name.

dev@jdg-developer-desktop ~/testtagging/test $ git config --global user.name "Manoj Kumar Bardhan"

Now, you can check again the user name after change/configure.

dev@jdg-developer-desktop ~/testtagging/test $ git config --global user.name
Manoj Kumar Bardhan

Now you can see the old user name was "manojkumar.bardhan" and new user name is "Manoj Kumar Bardhan".

It worked for me, hope it will help you.

How to Create a Git Tag

How to create tagging on git.

Really creating tag is  one of the best practice for development and maintain version. 

As per my understanding production release for your code is a nightmare , we don't know what will happen ???????

Also to maintain the code base stable and safety we need this tagging. This is quite often developers do google for tagging the their code (branch / master) for safety and reference future use.

This is quite simple , and below example will help you to understand the commands on command line.

Clone your code branch (use clone command to clone the code)

git clone https://your.user.name@stash.jdgnet.com.au/scm/enabler/testcode.git

Switch your expected branch (i.e.  bugfix/jdctagging) , which you want to create tagging and make sure you are inside the expected branch.

dev@jdg-developer-desktop ~/jdgtaggingdemo/test $ git checkout bugfix/jdctagging
Branch bugfix/testing set up to track remote branch bugfix/jdctagging from origin.
Switched to a new branch 'bugfix/jdctagging'
dev@jdg-developer-desktop ~/jdgtaggingdemo/test $ git branch
* bugfix/jdctagging
  master

Create the tag with below command, you can specify the tag version name.

dev@jdg-developer-desktop ~/jdgtaggingdemo/test $ git tag -a "v1.taging.version1" -m "commiting with for test tagging for my branch code"

Check the tag got created on above command.

dev@jdg-developer-desktop ~/jdgtaggingdemo/test $ git tag
v1.taging.version1

Push the newly created tag into remote server (stash)

dev@jdg-developer-desktop ~/jdgtaggingdemo/test $ git push origin v1.taging.version1
Password for 'https://your.user.name@stash.jdgnet.com.au':
To https://your.user.name@stash.jdgnet.com.au/scm/enabler/test.git
 * [new tag]         v1.taging.version1 -> v1.taging.version1

If you don't want to push the tag by name and you want to push all tags then use below command. In my example I have only created one tag and I didn't use the below command.

git push origin --tags

Now you can see the [new tag] got created on remote server. See the snapshot below , showing the tag on stash.

How to Mock Private Fields of a Class for JUnit Testing

This is really very tricky and major concern for developers. Specially who are not following TDD(Test Driven Development ) process.

Of course it not the challenge for java developer to get this done, but when there is a time period to deliver your project. ohh god !!! you only can save me.

By the way , I also faced same issue with my recent project. After some kind of investigation .. and its weird. 

Actully I was using Junit with Mockito. I tried with mockito , but no luck. Hence mockito will not allow you to set the private fields . 

Finally I tried with Reflection to enforce the private variable to set the data using ReflectionTestUtils.

import org.springframework.test.util.ReflectionTestUtils;

 

Sample code fix using Junit Test (Reflection API) :-

/**
 * This class contains your private variables those you want to mock.
 */

public class MyObjectImplImpl {
    private String fieldName1;
    private String fieldName2;

}

Test Class (MyObjectImplTest.java):-

public class MyObjectImplTest {

    @InjectMocks
    MyObjectImplImpl myObjectImplImpl;

    @Before
    public void before() {
        myObjectImplImpl = mock(MyObjectImplImpl.class);
        myObjectImplImpl = new MyObjectImplImpl();
        //Set the private variable values here by reflection.
        ReflectionTestUtils.setField(myObjectImplImpl, "fieldName1", "setnew-field-value-1");
        ReflectionTestUtils.setField(myObjectImplImpl, "fieldName2", "setnew-field-value-2");
    }

    
    /**
     * Your Test Method.
     */
    @Test
    public void testJavaDeveloperGuide() {
       //do your test case here.
    }

}

This is working fine for me.


Either the alternative is you can try power-mock , instead of mockito. Powermock is working for this issue. This will fix this private field access issue. Also its more powerful than mockito.



Happy coding.........!!!

How to Test a Web Service Using cURL from the Command Line

How to test web service using command line curl.

How to test web service using command line curl, is a very often requirement.

This is always very easy to call the web service via a java client,  but sometimes we need to call the service using curl.

One thing you know ? its really very tactical to  call the web service from terminal/command line using curl command.


I have  steps with sample example :-

You need to know the below things before calling the service via curl.

Service Endpoint - The web service endpoint you want to call.

Example - http://myserverip.mycorpnet.com.au:16500/NaaSAutomation/NaaSManageService

Operation Name - The operation name , you want to execute.

Example - readProviderRequest

SoapAction - The soap action defined in WSDL.

Example - SOAPAction:/NaaSAutomation/Resources/WSDLs/ESB/Service/NaaSManageService-service0.serviceagent/NaaSManageServicePortEndpoint0/ManageProviderRead

Create sample valid request xml for sending to the service.

Request.xml
------------------

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:dto="http://dto.service.myservice.networkservice.test.service.mycorp.com.au/">
   <soapenv:Header/>
   <soapenv:Body>
      <dto:readProviderRequest>
         <callerIdentity>myIdentity</callerIdentity>
         <dto:ProviderName>techbyteslearn</dto:ProviderName>
      </dto:readProviderRequest>
   </soapenv:Body>
</soapenv:Envelope>

Curl Command :-

curl --header "Content-Type: text/xml;charset=UTF-8" --header "SOAPAction:/NaaSAutomation/Resources/WSDLs/ESB/Service/NaaSManageService-service0.serviceagent/NaaSManageServicePortEndpoint0/ManageProviderRead" --data @Request.xml http://myserverip.mycorpnet.com.au:16500/NaaSAutomation/NaaSManageService

Response got from Curl :-

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
   <SOAP-ENV:Body>
      <ns0:ManageProviderCreateRes xmlns:ns0="http://www.mycorpnet.com.au/NaaSAutomation/Resources/Schemas/CreateRequest.xsd">
         <ns0:response>
            <ns0:providerName>techbyteslearn</ns0:providerName>
            <ns0:createStatus>SUCCESS</ns0:createStatus>
            <ns0:rollbackInitiated>TRUE</ns0:rollbackInitiated>
         </ns0:response>
      </ns0:ManageProviderCreateRes>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Jenkins Maven Error: Unknown Lifecycle Phase "mvn"

[ERROR] Unknown lifecycle phase "mvn" You must specify a valid lifecycle phase or a goal in the format.

This Jenkins issue is very common, while configuring the maven job in Jenkins. One of my peer faced this issue during her development. Then we investigate and fixed this issue.

Solution :-

Its a simple mistake, that while configuring the jenkins jobs maven goal, we are simple trying with mvn clean install  , which is a against maven life cycle policy.

So , we fixed this by removing the mvn  . Correct command is clean install. Then it worked.

JAXB Marshalling: Convert Java Object to XML

JAXB Marshalling - Converts Java Object to XML. 

You need to JAXB library jar , download from here.

Really JAXB makes developers life easy and help to develop stable and reliable coding. Below Example shows how to convert the Java object into XML format.

Book.java

package com.techbyteslearn;

 

import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement
public class Book {
private String name;
private String author;
private String price;
public String getName() {
return name;
}
@XmlElement
public void setName(String name) {
this.name = name;
}
public String getAuthor() {
return author;
}
@XmlElement
public void setAuthor(String author) {
this.author = author;
}
public String getPrice() {
return price;
}
@XmlElement
public void setPrice(String price) {
this.price = price;
}
}

JAXBObjectToXML.java

package com.techbyteslearn;
import javax.xml.bind.JAXBContext;
import javax.xml.bind.JAXBException;
import javax.xml.bind.Marshaller;

public class JAXBObjectToXML {
/**
* @param args
*/
public static void main(String[] args) {
Book book=new Book();
book.setAuthor("M Bardhan");
book.setName("Java Cookbook");
book.setPrice("$200");
try {
JAXBContext jaxbContext=JAXBContext.newInstance(Book.class);
Marshaller marshaller=jaxbContext.createMarshaller();
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT,true);
marshaller.marshal(book, System.out);
} catch (JAXBException e) {
System.out.println("Error occured ::"+e.getMessage());
}
}
}

Output XML :-

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<book>
    <author>M Bardhan</author>
    <name>Java Cookbook</name>
    <price>$200</price>
</book>

Tomcat WAR Deployment: Properties File Not Found

This issue I faced while loading the war file on Tomcat. This may be a minor issue, but I faced this issue and spend some time to fix this issue.

Actually , I was working on Tomcat newly and I was not sure what configuration we need to load the properties file. Normally all the properties files are placed in class path.

I placed the properties file inside the Tomcat , but I don't know why this issue was coming.

Issue log :-

The issue was , tomcat loader was not able to locate the file . So , you need to configure this manually. 

Finally , I fixed this by configure the properties directory in tomcat. You need to explicitly mention the properties location from where your tomcat can read the library and other properties. But, its not always advisable .

You can add the <Tomcat Home Directory> into catalina.properties file. 

Example :-

 shared.loader=/usr/java/apache-tomcat-7.0.41

Note :- Catalina.properties file is inside <Tomcat Home Directory> /conf
