Apache Directory Studio - An Error Has Occurred

By Sagar Chaudhari
Have you ever faced an error while launching Apache Directory Studio? I faced this error recently on my MAC OS.

Problem:

I was using Apache Directory Studio for past few months without any issues, but yesterday all of a sudden I was getting below error while I was attempting to launch Apache Directory Studio application on my MAC. Note that I am using Apache Directory Studio version 2.0.0.v20130628


I open the log file to check the error message, it was so confusing. Error message was something like this:
!MESSAGE FrameworkEvent ERROR
!STACK 0
org.osgi.framework.BundleException: The bundle "org.eclipse.equinox.common_3.6.100.v20120522-1841 [1]" could not be resolved. Reason: Missing Constraint: Bundle-RequiredExecutionEnvironment: CDC-1.1/Foundation-1.1,J2SE-1.4

Root Cause:

I recently installed latest Java version i.e. Java 9 on my MAC and I encountered this issue due to the Java version upgrade. The error message in the log file is bit misleading.

Solution:

To resolve this issue, you can follow below mentioned steps:
  1. Click here and refer my other post to install multiple versions of Java on your MAC OS.
  2. Make sure you install Java 7 on your MAC OS.
  3. Execute this command to get the Java 7 location: /usr/libexec/java_home -v 1.7
  4. Now open Finder and click on Applications
  5. Next, locate Apache Directory Studio.app and right click
  6. Select Show Package Contents
  7. Go to Contents >> MacOS folder
  8. Create ApacheDirectoryStudio.ini file if not present already
  9. Add following contents (note that there are two lines) and save the file. 
  10. Now, when you attempt to open Apache Directory Studio, it should open without any issues.
-vm
<Java_7_Location>/bin

How to Extract Values from Response Header in JMeter?

By Sagar Chaudhari
JMeter is a powerful tool for API testing. Let's say you are are writing test cases for one of your RESTful service; and you want to extract and validate the value returned as part of response header. It is little bit tricky to extract the value from Response Header in JMeter , but it is possible. For example, your RESTful service returns "ETag" in response header. When you look at the raw response data, the value is displayed something like this: ETag: 2666d92fa9ebf10250acdb235546f045 To exact value of this reaponse header in JMeter: Right click on your HTTP request, then add Post Processor element - Regular Expression Extractor Select Radio button - Main sample only Select Radio burron - Response Headers Type some name in Reference Name section - for example, eTagVariable Type this expression in Reference Expression section - ETag:\s+(.+) IMPORTANT: This expression will select pick the ETag response header parameter and select everything after colon bla...

MuleSoft - Static IP Addresses and Multiple Workers

By Sagar Chaudhari
Did you just realize that your Mule Application requires horizontal scalling ? Well, thats easy - just go to CloudHub Runtime Manager, select your application and change the "Workers" count from 1 to either 2, 3 or 4. If numbers are grayed out, then you might have to adjust the "Worker Size", or purchase additional capacity from MuleSoft. So, what is the issue then? At the time of the blog post, based on Mule documentation, if you are using only 1 worker and if you want to apply static IP, then you can simply navigate to "Static IPs" section in Runtime Manager and allocate the static IP address. The issue is when you want to apply Static IP addresses for more than 1 workers for various reasons including IP whitelisting. Based on Mule documentation you cannot apply static IPs if you are using more than 1 worker. From Mule Documentation: "Static IPs are not supported for private IP addresses inside a CloudHub VPC and it is only supported for app...

Setup OpenLDAP on MAC

By Sagar Chaudhari
macOS (Mac OS X or OS X) is the current series of Unix-based graphical operating systems developed and marketed by Apple Inc . designed to run on Apple's Macintosh computers ("Macs"). Within the market of desktop, laptop and home computers, and by web usage, it is the second most widely used desktop OS after Microsoft Windows . Recently, while working on one of my projects, there was a requiremnt to integrate our system with LDAP i.e. Lightweight Directory Access Protocol ( LDAP ). So, I wanted to try out some samples by installing OpenLDAP on my MAC. Initially, it looked streightforward but later I realized that there are multiple steps involved to get OpenLDAP up and running in my Mac. So, I thought of documenting various steps so that others can refer them. What do you need to begin? MAC Obviously you need MAC because these steps will work only for MAC (Sorry Windows users) Homebrew This is a package manager for macOS. Click here and follow the instructio...

MuleSoft LDAP Connector With Example

By Sagar Chaudhari
As we all know, the L ightweight D irectory A ccess Protocol ( LDAP ) is an open, vendor-neutral, industry standard application protocol for accessing and maintaining distributed directory information services over an Internet Protocol (IP) network. A common use of LDAP is to provide a central place to store usernames and passwords. This allows many different applications and services to connect to the LDAP server to validate users. This has a major benefit that allows a central place to update and change user passwords. With MuleSoft’s LDAP Connector , we can access and maintain directory information services over an IP network by connecting to any LDAP server. LDAP Connector is developed by MuleSoft's developer community and it is categorized as Community Connectors. Latest LDAP Connector documentation is available here . Unfortunately, the information and examples of this connector are limited and scattered all over the web. Today, I am trying to cover as many details as p...

MuleSoft - JSON Schema Validation with Dynamic Schema Location

By Sagar Chaudhari
While working on a Mule Application project, if you a planning to validate JSON payload against some JSON schema , and more importantly if you want to pass schema location dynamically, then this post will be benificial for you. Mule provides JSON Schema Validator as out of the box feature. From mule documentation , evaluates JSON payloads at runtime and verifies that they match a referenced JSON schema. You can match against schemas that exist in a local file or in an external URI. If the validation fails, an exception is raised with feedback about what went wrong and a reference to the original invalid payload. Above code works but here is the catch, in my scenario, the schema location was dynamic. Let's say the schema location is present in the database. Once the schema location value is retrieved from database, it is stored in a flow variable. For simplicity, I am creating a flow variable with hard-coded value. In actual application, the flow variable value will be the va...

Access GitHub Repositories with SourceTree and 2FA (2 Factor Authentication)

By Sagar Chaudhari
Many developers and organizations use GitHub as code repository. Similarly, many prefer to commit code in GitHub repositories using various commands. I personally think that using any kind of user interface for committing code and performing various GIT operations is much more simpler and productive. SourceTree is one such Atlassian product. SourceTree is a free Git client and provides beautiful GUI that offers a visual representation for various Git repositories. For added security, you can enable 2FA (i.e. 2 Factor Authentication) for your GitHub account. Configuring GitHub with SourceTree is very very simple. Here are the steps on MAC OS (steps on Windows OS are similar): If you have not enabled 2FA: Open SourceTree and go to Preferences Select Accounts Click on Add button to add account On the pop-up window, select Host as "GitHub" Select Auth Type as "Basic" Type your GitHub username (not email) Type your password Select Protocol as HTTPS...
