<h1 class="topictitle1">Java file authorities in the integrated file system</h1>
|
||
|
|
<div><p>To run or debug a Java™ program, the class file, JAR file,
|
||
|
|
or ZIP file needs to have read authority (*R). Any directories need read and
|
||
|
|
execute authorities (*RX).</p>
|
||
|
|
<p>To use the Create Java Program (CRTJVAPGM) command to optimize
|
||
|
|
a program, the class file, JAR file, or ZIP file must have read authority
|
||
|
|
(*R), and the directory must have execute authority (*X). If you use a pattern
|
||
|
|
in the class file name, the directory must have read and execute authority
|
||
|
|
(*RX).</p>
|
||
|
|
<p>To delete a Java program by using the Delete Java Program
|
||
|
|
(DLTJVAPGM) command, you must have read and write authority (*RW) to the class
|
||
|
|
file, and the directory must have execute authority (*X). If you use a pattern
|
||
|
|
in the class file name, the directory must have read and execute authority
|
||
|
|
(*RX).</p>
|
||
|
|
<p>To display a Java program by using the Display Java Program
|
||
|
|
(DSPJVAPGM) command, you must have read authority (*R) to the class file,
|
||
|
|
and the directory must have execute authority (*X).</p>
|
||
|
|
<div class="note"><span class="notetitle">Note:</span> Files and directories that do not have execute authority (*X) always
|
||
|
|
appear to have execute authority (*X) to a user with QSECOFR authority. Different
|
||
|
|
users can get different results in certain situations, even though both users
|
||
|
|
appear to have the same access to the same files. This is important to know
|
||
|
|
when running shell scripts using the Qshell Interpreter or java.Runtime.exec().</div>
|
||
|
|
<p>For example, one user writes a Java program that uses java.Runtime.exec()
|
||
|
|
to call a shell script, then tests it using a user ID with QSECOFR authority.
|
||
|
|
If the file mode of the shell script has read and write authority (*RW), the
|
||
|
|
integrated file system allows the user ID with QSECOFR authority to run it.
|
||
|
|
However, a non-QSECOFR authority user could try to run the same Java program,
|
||
|
|
and the integrated file system would tell the java.Runtime.exec() code that
|
||
|
|
the shell script cannot be run, because *X is missing. In this case, java.Runtime.exec()
|
||
|
|
throws an input and output exception.</p>
|
||
|
|
<p>You can also assign authorities to new files created by Java programs
|
||
|
|
in an integrated file system. By using the os400.file.create.auth <a href="sysprop.htm">system
|
||
|
|
property</a> for files and os400.dir.create.auth for directories, any combination
|
||
|
|
of read, write, and execute authorities may be used.</p>
