Out Of Memory!

Recently, I thought of upgrading various softwares on my MAC OS including Java, AnypointStudio and all other softwares. So, I downloaded new version of MuleSoft Anypoint Studio on my MAC OS. After installing AnypointStudio, when I opened it for the first time, I immediately encountered an issue. Guess what, the very first screen - Workspace Launcher was frozen. I was not able to type-in workspace location, I was not able to click on browse button, I was not able to click on cancel or ok button. What a bummer!! After some trial and errors, I finally found the solution to fix the problem. I am not sure why, but looks like Anypoint Studio does not work with Java 9. As part of upgrade process, I had upgraded the Java version from 7 to 9. Either you will have to uninstall Java 9 and go back to Java 7 (I did not test this with Java 8) or you can follow below steps to make it work. Install Java 7 in addition to Java 9 on MAC OS. Get the Java 7 location, we will need this location....

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...

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...

Decompilers are one of the most important tool for developers. Many Java developers use Eclipse IDE and many MuleSoft developers use Anypoint Studio (just another flavour of Eclipse) for their development work. We can easy configure decompiler for these IDEs. Here are the simple steps (for both IDEs): Download update site archive from here . Unzip the archive and note the location/path Open Eclipse or MuleSoft Anypoint Studio  Click on "Help" Select "Install New Software..." Click on "Add..." button On the pop-up, type name as "Java Decompiler" (or any other name) Click on "Local..." button Select the unzip location (Step 2) Click "OK" button to close the pop-up Select checkbox: Java Decompiler Eclipse Plug-in Click on "Next" Select "Yes" for the agreement Select "Finish" Restart Eclipse or MuleSoft Anypoint Studio Now, Eclipse or MuleSoft Anypoint Studio can decompile Java ....

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...

In today's enterprise infrastructure, system and application integration is more and more frequently a mission critical concern. There are number of Enterprise Service Bus (ESB) products available in the market today. These products can help you remove basic dependencies between applications by eliminating the need for one application to be aware of the other's location, but connectivity is not the only issue. In reality, most systems do not speak same language so Data transformation is one of the most important topic in Integration space. Data transformation is the process of converting data or information from one format to another, usually from the format of a source system into the required format of a new destination system. MuleSoft has developed " DataWeave " - a new language and module for querying and transforming data. DataWeave is a full-featured and fully native framework for querying and transforming data on Anypoint Platform. Fully integrated with t...

Many companies use standard protocols such as FTP and SFTP to transfer files to external partner and receive files from external partners. Using FTP and SFTP provides simple to use and low cost platform for file exchange. In some business scenarios, companies may have to exchange sensitive information such as employee’s personal information, expense reports, payment information etc. Mule has the ability to encrypt a message payload, or part of a payload, using Pretty Good Privacy ( PGP ). PGP combines data compression and data encryption to secure messages. The compression reduces message transmission time between origin and destination. There are two scenarios that this document addresses: Using another party’s public key to encrypt a messages in a Mule application Using one’s own set of private and public keys so as to accept, and decrypt messages in a Mule application. What is Pretty Good Privacy (PGP)? Pretty Good Privacy ( PGP ) is a data encryption and decryption ...
