Same tomcat context file serving multiple workspace

In development we encounter a common scenario of working on multiple branches @ a same time. For this we generally keep multiple copies of context file for each branch.

Ex: We have two branch, that has code in workspace_one and workspace_two, so for running code from each branch we need two context file like below

<Context docBase="F:\workspace\workspace_one\xyz\target\endpoint-1.0.0-SNAPSHOT" >

</Context>

<Context docBase="F:\workspace\workspace_two\xyz\target\endpoint-1.0.0-SNAPSHOT" >

</Context>

Similarly if we are working on n no of  branches then there will be  n no of context files.

Solution:

-DAPP_PATH="F:\workspace\workspace_one"  set this in VM arguments either from command line from where you are running tomcat or in eclipse configuration under VM arguments.

Modified the single copy of context file:

<Context docBase="${APP_PATH}\xyz\target\endpoint-1.0.0-SNAPSHOT" >
 </Context>

So each time you just need to make change in VM arguments before starting the tomcat only. No need to switch all context files.
