Java In A Nutshell, 5th Edition

Synopsis

jstack [ options ] pid // local process jstack [ options ] executable core // core file jstack [ options ] [ process-name @] hostname // remote process

Description

jstack prints stack traces for each of the Java threads running in the specified Java process. jstack can be started in three ways:

• Specify the process id of a Java process running locally to obtain configuration information about it. See jps to list local processes.

• To obtain post-mortem configuration information from a core file, specify the Java executable that produced the core file and the core file itself on the command line.

• To obtain configuration information about a Java process running remotely, specify the name of the remote host, optionally prefixed by a remote process name and @ sign. jsadebugd must be running on the remote host.

In Java 5.0, jstack is experimental, unsupported, and not available on all platforms.

Options

-help, -h

Prints a help message.

-m

Displays stack traces in "mixed mode," that is, displays both Java and native method stack frames. Without this option, the default is to display Java stack frames only.
