The great experience,which I got through the two days[26th &27th April 2012] Outbound Training done with Wild-Drift  inspired me to write this blog. This training was organized from our company [ WSO2 ] and all the employees supposed to go through it.Before involve in the training I was under the impression that this is an adventurous program.Hence had a feeling of bit scared. But once I undergo through the training I realized this is not for adventure purposes.It's all about improving our selves  and how we can improve our selves on  team-working and how we can contribute effectively on the company goal. We have had few team activities and from each activity I gained a lot of learning as well the experience.And it's not to forget the fun and joy we have had in each activity as well.Additionally the images which I attached in this blog will prove the great natural scenes that we were able to watch during the time being there. ...

Say you want to transfer files over a network in a secured mannar.Here comes the usecase of SFTP[Secure File Transfer Protocol]. SFTP is a secured protocol which is an extention of the Secure Shell protocol(SSH) provides capabilities as file accessing,file transferring and file management. This protocol encrypts both commands and data and ensure not transmitting of passwords and sensitive information over the network.SFTP functionality is similar to FTP,but since FTP uses a different protocol,you cannot use FTP client to talk to an SFTP server. To use SFTP capabilities,you can try out either graphical SFTP client or either at the command line. At command line -[In Unix or Mac OS environment] Start a SFTP session by 'sftp username@hostname' Then enter the password when prompted. Then with using sftp commands you can try-out file operations.[To get SFTP commands type 'help'] When you are using command line to SFTP operations you'll mostly remember about SCP protocol...

If you are have ever try-out WSO2 ESB[1],you are quite familiar with WSO2 ESB proxy services. A proxy service is a some kind of virtual service,which fronts an existing actual service end-point and which is hosted under WSO2 ESB. Clients can send requests for proxy servic es hosted in ESB,as the client sees that service hosted in ESB without knowing of actual service end-point.Such proxy service has own WSDL which can be view from '?wsdl' parameter. Advantage of such a proxy service is t hat proxy services can mediate the sending messages to the actual service,before they are delivered to the actual end-point and can mediate the responses before those reach the client. There are several templates for proxy services as below and you can get more info on proxy services from [2]. Pass Through Proxy- Create a simple proxy service on a specified endpoint. This proxy service does not perform any processing on the messages that pass through the proxy. Secure Proxy-Create a proxy serv...

As the first post in 2012,thought of sharing some confusing error messages which will appear while going to commit on Subversion.This blog-post will continue further as I found more such svn warnings. 1) Aborting commit - has no Ancestry information Eg: .../rootFolder/svnProject$ svn commit . svn: '/path/to/my/rootFolder' has no ancestry information Reason: While SVN checking for folder structure,if some parts of the folder tree above the folder being commited have svn metadata and some do no t,this error will appear. Solution: Check the ancestor folders (especially above the folder reported in the commit failure message) and if you find an .svn/ folder in any of them,remove it. Alternatively, move the folder another location where it has no ancestor folder with .svn/ within it. 2) Aborting commit: remains in tree-conflict Reason: a) A file/directory is locally deleted but exists and is modified in the repository b) A file/directory was locally modified but is deleted i...
