Two nice articles are published related to Oracle Service Bus (OSB), previous known as BEA Aqualogic Service Bus, when you using the OSB to call a BPEL process. The first error you get when you want to access BPEL process is:
An unexpected error occured accessing information about the WSDL of the service:
com.bea.wli.config.component.NotFoundException: Can not compute effective WSDL for : BusinessService Chapter19/BusinessServices/AddIntegers
The solution of this error is described by Berthold Maier’s Weblog and Anthony Reynolds blog. Just remove the partner link definitions from your BPEL WSDL:
<!--
<plnk:partnerLinkType name="HelloWorld">
<plnk:role name="HelloWorldProvider">
<plnk:portType name="tns:HelloWorld"/>
</plnk:role>
</plnk:partnerLinkType>
-->
