Resolution

Restful Webservices are not supposed to be created by our customers within our EAR. Customers are free to use the supported product customizations (as per our documentation) and deploy them to the respective folders like custom folder. We do not support Custom restful web services.  The documentation does not have any references for the same.

Customer's team was able to find a way to create custom web services which worked fine in 14.2. Since we do not support custom web services, we cannot guarantee to it to work in 14.3 and higher versions.

Since custom web services are not supported, we provide best effort support. Our recommendations are below.  It is based on the JEE application server container specification standards to avoid class loading conflicts between the application server and the applications (modules).  

 

1) Create a custom restful Webservice jar and deploy it along with its dependent jars into user_console.war/WEB-INF/lib folder and test all the service.  Test it to make sure it is working from user_console.war/WEB-INF/lib location.

2) Please Create a war file which includes your services as well as its dependency and deploy it under im_iam.ear folder. 

 

For further assistance with your customizations and working with 14.3 and above please continue to work with your Broadcom Account team and if needed engage with our Services teams and partners.
