Currently we have only a tomcat installed and all are directly

Is there a way to cache these websercice calls using apache.
If so kindly provide me the details or please let me know the reasons
for not being cached.
Apache HTTP Server can certainly cache content, see
https://httpd.apache.org/docs/2.4/caching.html Be sure to read the
sections "What Can be Cached?" and "What Should not be Cached?"
However, caching for a web service call only makes sense if the call
will always return the same output for a given set of
arguments/parameters and the call does not have any side effects. For
example, it would be safe to cache the results of call for "return a
thumbnail of the image a.png" but it would not be safe to cache the
results of a call for "add a new description for part number 12345".
Also note that web service calls using the HTTP POST method may be
difficult or impossible to cache.
Often, caching is used only for static content, as it can be tricky --
or inappropriate -- to correctly set up caching for dynamically
generated content.
Instead of caching web service calls, you may want to analyze how Tomcat
is spending its time and see if the code of your web application can be
made more efficient.
