Is it possible to say what are these both and what are they differ in?

Answer 1

WST

• Stands for web standard tools
• provides support for building multi-tier Web applications
• WST Link
• The server component contains the Server Tools framework and adapters for selected servers. At the WST level, the server component is a very generic infrastructure.

JST

• Stands for j2ee Standard Tools
• provides support for building multi-tier J2EE applications
• JST Link
• The server component contains the J2EE Server Tools framework and adapters for selected popular J2EE servers such as Apache Tomcat.

Answer 2

The WST server components provide generic support for servers, whereas the JST components provide specific support for J2EE servers.

If you drill down into the WST Component and JST Component documentation it gives a bit more detail.
