Publish a service which provides both XML/JSON via SOAP/REST protocols in WSO2 ESB

Let's say we want to define a service in WSO2 ESB that provides the same information using different formats and protocols. It should provide both XML and JSON formats (for example 2 operations) and should be provided as SOAP and REST.
This service will consume a DSS service we will deploy as SOAP and as REST.

What is the best way to achieve this via WSO2 ESB?

1. The best approach is to use a proxy for support XML and invoke SOAP endpoint and an API for support JSON and invoke REST endpoint.

2.Then the problem is, publishing it as a proxy we get all the facilities provided in the dashboard. If we use an API we do not have the dashboard options available (statistics, mediation tracer...)

As a solution:
a. we can move the content of the API to a separate sequence then we can get the dashboard options.
b. publish them via a BAM

3. Further, we can define a sequence which transform XML to JSON and vice versa in both Proxy and API and share it with both API and Proxy.

Tips on using environment variables in WSO2 Integration Cloud

Environment variables allow you to change an application's internal configuration without changing its source code. Let’s say you want to deploy the same application in development, testing and production environments. Then database related configs and some other internal configurations may change from one environment to another. If we can define these configurations as an environment variables we can easily set those without changing the source code of that application. When you deploy your application in WSO2 Integration Cloud, it lets you define environment variables via the UI. Whenever you change the values of environment variables, you just need to redeploy the application for the changes to take effect. Predefined environment variables Key Concepts - Environment Variables provides you some predefined set of environment variables which will be useful when deploying applications in WSO2 Integration Cloud.

VFS access SFTP with special character password

Learn WSO2 ESB VFS Transport https://docs.wso2.com/display/ESB481/VFS+Transport When we need to access the FTP server using SFTP, VFS connection-specific URL need to be given as : <parameter name="transport.vfs.FileURI">vfs:sftp://username:p@ssword@ftp.server.com/filePath?vfs.passive=true</parameter> When the password contains a special characters (eg: p@ssword), it gives the following error. 2015-03-27 13:06:03,766 [-] [PassThroughMessageProcessor-5] ERROR VFSTransportSender cannot resolve replyFile org.apache.commons.vfs2.FileSystemException: Invalid absolute URI "sftp://username:***@ftp.server.com/filePath?vfs.passive=true".
