Many occasions, you might have come across the circumstances where you may want to know the version of the application deployed for particular instances like System testing, UAT and production. Possible situations are,
1. As part of post deployment activity, you may
wanted to ensure the whether the deployed build(s) is successfully deployed or
not.
2. To see the version of the build deployed in
production (to know the stable version of the build). You might have seen many
open source applications for this.
Ant target to achieve
the same:
Java Class file that can
read the MANIFEST.MF file attributes:
Code is self
explanatory. We have a small piece of
Code to get the ServertContext from FacesContext. If you are not using JSF, replace with relevant
code base.
JSF presentation file
used to display the MANIFEST.MF file attributes:
Below is the design view
of the presentation. Bean attribute values will be populated using VersionInfoMFReader.java class file as mentioned above. Here,
presentation values will be populated from the bean as below.
We have implemented the
above version info reader in our application. Sample application screen print
attached below.
