JPS command error: malformed host identifier

I found in the JPS command docs that we can set the RMI registry port in the host identifier.

I tried the following

jps XX.XXXX.X.XX:8725

It returns a weired error: 

Malformed Host Identifier: XX.XXX.X.XX:8725

usage: jps [-help]

jps [-q] [-mlvV] [<hostid>]

Definitions:

<hostid>:      <hostname>[:<port>]

Am I doing something wrong?

Solution

  • the key is "< hostname >" not IP

    If I put my IP, I get the same response, but works if I put my host name.
