The Java/Javac versions and the JAVA_HOME and PATH variables were configured properly.

Also the java runtime was configured properly in appengine-web.xml

After little struggle,  the root cause of the issue was with wrong configuration of PATH environment variable.

Other Java executables added to the PATH variable caused the SDK to choose the JRE version for deployment. 

The issue got fixed after changing the order of PATH variable - moved up the JAVA bin path over other path configurations

How to include dynamic custom script to websites through GTM(Google Tag Manager) - Adobe Experience Manager(AEM)

How to include dynamic custom script to websites through GTM(Google Tag Manager) - Adobe Experience Manager(AEM)

Google Tag Manager is a tag management system that allows you to quickly and easily update tracking codes and related code fragments collectively known as "tags" on your website or mobile app. Once a small segment of Tag Manager code has been added to your project, you can easily configure and deploy your tag configurations from a web-based user interface without the need to deploy additional code in most cases. This reduces errors and frees you from having to involve a developer every time you need to make changes.

This post explains the approach to use Google Tag Manager(GTM) to include the dynamic scripts as part of Adobe Experience Manager(AEM) websites.

Create a free google tag manager account if one is not available

Install the GTM header and body scripts to the AEM website

Copy the head script to the header file and body script to body footer(start of body section)

How to display the git tags based on the environment in Jenkins parameter

How to get the basic profile details of a user in external clients through OAuth - AEM

This post will explain how to display the git tags based on the environment in Jenkins parameter - Displaying the dynamic list with tag names filtering the tags with environment name e.g. QA, UAT, PROD(the environment name should be included in the tag while creating)

Select "This build is parameterized" in Jenkins job configuration
Add new parameter of type Extensible Choice
Enter the name "Tag" and select the Choice Provider as "System Groovy Choice Parameter"
Enter the below script in "Groovy System Script"

def gettags = "git ls-remote -t https://username:[email protected]/project/repo.git".execute()
def tags = []
def t1 = []
gettags.text.eachLine {tags.add(it)}
for(i in tags)
{
   def tagName=i.split()[1].replaceAll('\\^\\{\\}', '').replaceAll('refs/tags/', '')
   if(tagName.contains('QA'))
      t1.add(tagName)
}
t1 = t1.unique()
return t1

Change the git repository details and the string based on that the tags should be filtered e.g QA, UAT, PROD

Click on "Run the script now" to test the script - this will displayed the filtered tags.
Save the configurations finally

Disable "Must Not Contain URL" validation in the hidden field that expecting the URL as input.

How to display the dynamic popup in a page through GTM?

How to display the dynamic popup in a page through GTM?

This post will explain how to display the dynamic popup in a page through GTM.

The assumption is the required JQuery scripts are included as part of the page.

Define the cookie type variable:

• Click on Variable in left hand side menu.
• Go to user defined variables and select new.
• Select variable configuration as 1st party cookie 
• Give cookie name as popUpDisplayed and check url decode cookie option.
• Save the changes and give the name as popUpDisplayed.

Integration of Jenkins server with GIT Hub

Integration of Jenkins server with GIT Hub

We are having multiple blogs around this but could not able to find the complete information on this.

Thought of sharing this for my reference too. This post will explain how to integrate Jenkins in Linux with private GIT Hub.

Configuring the GIT plugin in Jenkins:

Jenkins à Manage Jenkins à Manage Plugins

Make sure Jenkins GIT Client Plugin and Jenkins GIT plugins are installed.

Configure GIT in server:

Login to Jenkins server via puty

Execute the following command - sudo yum install git-all

Configure GIT executable path:

Jenkins àMange JenkinsàConfigure System

Enter the git executable path(git installed to the server in previous step)

My case the path is /usr/bin/git, change accordingly

SSH Configuration:

Login to Jenkins server via putty

Execute the following commad - sudo -u jenkins ssh-keygen -t rsa

Enter the details accordingly, Passphrase is optional if required then enter some string.

This will create private and public keys under /var/lib/jenkins/.ssh (default files are id_rsa and id_rsa.pub)

java.util.concurrent.ExecutionException: hudson.util.IOException2: Failed to create a temporary file in xxxxx/figerprints/2c/73

java.util.concurrent.ExecutionException: hudson.util.IOException2: Failed to create a temporary file in xxxxx/figerprints/2c/73

We were receiving the following exception while executing the deployment jobs from Jenkins

java.util.concurrent.ExecutionException: hudson.util.IOException2: Failed to create a temporary file in xxxxx/figerprints/2c/73

Based on the analysis, the issue happened due to in sufficient space in the server.

The deployment got success after freeing some space in the server.

Pending - Waiting for next available executor/Disk space too low on /tmp - Jenkins

Pending - Waiting for next available executor/Disk space too low on /tmp - Jenkins

While we were trying to execute the job, it was displaying "Pending - Waiting for next available executor". When looking into the Jenkins node from the console, the Master node is offline and the error message displayed was "Disk space too low. Only xxxGB on /tmp" but the /tmp folder has space around 1GB.

Steps are followed to resolve the issue

• Increase the space available in /tmp folder. If not able to increase the space in /tmp folder then TemporarySpaceMonitor can be disabled or the memory threshold value of the TemporarySpaceMonitor can be reduced in $JENKINS_HOME/nodeMonitors.xml(make sure atleast minimum memory is available)

send-mail: fatal: open /etc/postfix/main.cf: No such file or directory - Linux

send-mail: fatal: open /etc/postfix/main.cf: No such file or directory - Linux

I was receiving the following exception "send-mail: fatal: open /etc/postfix/main.cf: No such file or directory" while trying to send the mail through cron job. But the main.cf file is available in the specified location /etc/postfix/main.cf.

I tried providing the complete permission to /etc/postfix/main.cf but this not resolved the issue.

Steps to fix the issue:

yum reinstall postfix

postfix stop
postfix start

window.location.href is not working while clicking on hyper link in IE

window.location.href is not working while clicking on hyper link  in IE

I was trying to redirect to a page while clicking on a hyper link with JQuery Ajax and java script windows.location.href

<a id="signout" href="">signOut<a/>

<script>
    $("#signout").click(function(){

                       $.ajax({
                        type : "POST",
                        async: false,
                        url : "/services/logout",                    
                        success : function() {
                                       window.location="/content/test/test.html";
 },
error : function() {
                                       window.location="/content/test/test.html";
}
});
    } );
</script>

This is working perfectly in both Firefox and Chrome but it is not working in IE.

In IE while redirecting the URL is stripped off to /content/test/(test.html got removed while performing the redirect)

The issue can be fixed as below by adding # in href attribute.

<a id="signout" href="#">signOut<a/>

How to enable SSH X11 forwarding in Linux?

How to enable SSH X11 forwarding in Linux?

The  X11 forwarding from putty using Xming was not working, the DISPLAY variable is not set(echo $DISPLAY) after opening the remote server session in putty(X11 forwarding is enabled in putty and also the display is specified as localhost:0.0)

The actual issue is the X11 forwarding was not enabled in remote linux server.

The following steps can be followed to enable the X11 forwarding in linux server.

Login to linux server through putty

vi /etc/ssh/sshd_config

Enable the following flags

AllowAgentForwarding yes

AllowTcpForwarding yes

X11Forwarding yes

Execute the following commands

service sshd restart

yum -y update xauth

yum -y install xauth

Now you will be able to perform X11 forwarding.

Expected a string but was BEGIN_ARRAY at line 1 column - Gson

Expected a string but was BEGIN_ARRAY at line 1 column 

I was receiving "Expected a string but was BEGIN_ARRAY at line 1 column" error while deserializing the json string to java object using Gson.

Model class:

public class EmailGroup{
private String type;
private String id;
private String name;
private String permissions;

public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPermissions() {
return permissions;
}
public void setPermissions(String permissions) {
this.permissions = permissions;
}
}

JSON Response:

{"emailGroup":{"type":"EmailGroup","id":"1","depth":"minimal","description":"","name":"sample","permissions":[2,5,4,3]}}

Gson gson = new Gson();
EmailGroup obj = gson.fromJson(jsonstring, EmailGroup.class)

The root cause of the exception is the permissions attribute defined in the model class is of type String but the type of permissions in the jsonstring is List.

To fix the issue convert the type of permissions in the model class to List<String>(type string will change based on the type of the list entries)

public class EmailGroup{
private String type;
private String id;
private String name;
private List<String> permissions;

public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public List<String> getPermissions() {
return permissions;
}
public void setPermissions(List<String> permissions) {
this.permissions = permissions;
}
}
