Using an Alternative Java Runtime

You can use either the imqsvcadmin command’s -javahome or -jrehome option to specify the location of an alternative Java runtime. (You can also specify these options in the Start Parameters field under the General tab in the service’s Properties dialog window.)

The Start Parameters field treats the backslash character (\) as an escape character, so you must type it twice when using it as a path delimiter: for example,

   -javahome c:\\j2sdk1.4.0
