wrapper.java.idfile

File to write the current Java id to. If set, a file containing the latest id of the Java process will be written to the specified location when the first Java process is launched. The id will increment each time the JVM is restarted. The first invocation will be 1. This is the same value returned by WrapperManager.getJVMId() or displayed in the log file. The file will be deleted when the Wrapper process has terminated and will contain the id of the previous JVM when the JVM is being restarted. This property is not set by default.

This property has no use for most applications. It can be useful to external applications which need to monitor the Java process's state however.

NOTE MEG |  | The Wrapper needs to be able to open and then write to this file whenever its status is changed. The Wrapper does include code which allows for the file being briefly locked by an external process. However, the Wrapper will fail with a warning in the log if the file remains locked for more that 1 second. This will not affect the operation of the Wrapper.

Example:

    wrapper.java.idfile=./myapp.java.id
