Hi,

Yes servlet.jar and servlet-api.jar is the same file. In case of tomcat servlet.jar is just renamed to servlet-api.jar.

You can verify extracting the two files servlet.jar and servlet-api.jar in different directories and then comparing the content.

How to extract jar file?

To extract the jar file use the following commands

For servlet.jar
jar -tvf servlet.jar

For servlet-api.jar

jar -tvf servlet-api.jar

Good Luck!
