ClearQuest Web Server Using Tomcat Implementation

Implement ClearQuest web services using Apache Tomcat, including the companion Report Launcher.

(1) ClearCase and ClearQuest are often deployed together and should offer parallel implementation solutions. In 2018, the ClearCase/ClearQuest roadmap had Tomcat solutions projected, with ClearQuest Tomcat targeted for December 2019. Currently, ClearCase has a Tomcat solution, but ClearQuest does not. ClearQuest should offer an equivalent Tomcat solution.

(2) If we need a ClearCase AND ClearQuest remote solution, we are now forced to either stay with a WebSphere only solution, or implement both ClearCase Tomcat and ClearQuest WebSphere, usually on the same server which requires significant resources.

(3) Tomcat is a significantly smaller and simpler environment to implement and maintain. This is critical for ClearCase/ClearQuest Administrator s who are not WebSphere administrators and have little to no WebSphere knowledge or experience. ClearCase/ClearQuest administrators focus is ClearCase and ClearQuest support, and they should not have to become WebSphere administrators or experts. We have deployed both ClearCase/ClearQuest with WebSphere and ClearCase with Tomcat, and our experience confirms the significant difference between the complexity of WebSphere and the ease of Tomcat. For ClearCase Tomcat, the ClearCase WAR files are just dropped into the Tomcat application directory and it was running.

(4) ClearCase remote server requires Tomcat for some of our sites. We experienced multiple cases where an install ClearCase WebSphere solution stopped working for unknown reasons, and new installs would not run. We worked with the help desk SWAT and could not get any of the sites working using WebSphere. The help desk SWAT finally directed us to use the Tomcat solution which was a fast and easy implementation. It is currently our only option for these sites. We experienced the simpler installation and deployment of the Tomcat Solution. We would like it for ClearQuest too, and a single solutions for our ClearCase/ClearQuest remote deployment.
