What are the minimum requirements to run WSO2 BPS?
Refer to BPS system requirements.
How do I deploy a third-party library into the BPS?
Copy any third-party jars into $BPS_HOME/repository/components/lib directory and restart the server. WSO2 BPS converts those jars to OSGi bundles and place them in <BPS_HOME>/repository/components/dropins directory.
Can I extend the management console UI to add custom UIs?

I already have a WSO2 Governance Registry instance that contains my organization's SOA metadata. Can I get WSO2 BPS to use that registry instance as the metadata store?
WSO2 BPS integrates with WSO2 Governance Registry out of the box. Refer Registry Management for the necessary steps involved in remote registry configuration.

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>
