<h3><a name="seccupol"></a>Create and edit policy files with the policy tool</h3>
|
||
|
|
|

|
|
<p>Java 2 Security uses several policy files to determine the granted permission for each Java program. The Java development kit and the Java runtime environment provides the policytool graphical application to edit these policy files. While the policy tool is available as part of the iSeries IBM Developer Kit for Java, it is recommended that you run the policy tool on a workstation. The policy tool is located in the <tt>bin</tt> subdirectory of the Java development kit installation root or the Java runtime environment installation root.</p>
|
||
|
|
|
||
|
|
<p>It is recommended that you always use this tool to edit any policy file to guarantee the syntax of its contents. Syntax errors in the policy file causes an AccessControlException during server startup and application run time. Identifying the cause of an AccessControlException is not an easy task. Extreme care should be taken when editing these policy files.</p>

|
|
<pre>C:\java\jre\bin\policytool</pre></li>
