[Solved]-java.io.FileNotFoundException: ...keystore.jks (No such file or directory) at java.io.FileInputStream.open(Native Method)-eclipse

you need to assign keystore path on server.xml of tomcat.

<connector 
     port="8443" maxthreads="200"
     scheme="https" secure="true" sslenabled="true"
     keystorefile="${path of key stokre}/keystore.jks" /*put the keystoer path*/
     keystorepass="changeit"
     clientauth="false" sslprotocol="tls"/>
