We allocate one panel tocontain the the CSV file name prompt, text field, and the Choose button. A second panel iscreated to contain the text area and scroll pane along with the Ok and Exit buttons. When you areusing the FlowLayout instead of the GridLayout it is quite common to have multiple panels in acontaining object. It provides a method of “controlling the flow” by grouping objects together.Notice listing lines 81 through 84.

In general, a VMdesigned to run on multiple platforms cannot make use of a distributed lock manager which wasintegrated into the OS kernel of one platform because the lesser platforms the VM runs on don'thave a prayer of ever having such a tool. If you store 100% of all data in a relational databasewhich is native to the platform providing the distributed lock manager and integrated with saidmanager, and you have a message queueing system which is integrated with the distributed lockmanager, and a message dispatching system which is not only integrated with the distributed lockmanager, but will rollback and redispatch the message when the process handling it hangs ordies, then and only then, can you think about using a VMbased language for development.
