BPEL Deployment Configurations
How to enable specific transports when deploying BPEL
To enable specific transports can be done by introducing service.xml to bpel file. You can configure the required transport by defining it in service.xml like below.
<transports> <transport>http</transport> </transports>
After that the service.xml should be referred by deploy.xml inside your bpel process. Sample deploy.xml is given below.
<deploy xmlns="http://www.apache.org/ode/schemas/dd/2007/03" xmlns:tns="http://wso2.org/bps/samples/CustomerInfo"> <process name="tns:CustomerInfo"> <in-memory>true</in-memory> <active>true</active> <provide partnerLink="CustomerInfoPL"> <service name="tns:CustomerInfoService" port="CustomerInfoPort"> <endpoint xmlns="http://wso2.org/bps/bpel/endpoint/config" serviceDescriptionReference="services.xml"/> </service> </provide> </process> </deploy>
