如何在Wso2 esb 4.5上安装BPEL Feature 3.2.2？

Question

I need to install some features on wso2 esb 4.5 . I have found an article about installing BPEL Feature 3.2.2 , but when I try that I get the following errors. Does 'wso2 esb 4.5' support BPEL ? Is there any documentation available?

You need to get WSO2 ESB 4.0.3 which is released with Carbon version 3.2.3 and try to install features from online P2 repo. New BPEL features compatible with Carbon 4.0.0 (which is WSO2 ESB 4.5.0 is based on)is not released yet and will be released soon.
