|
||
|
|
<div><p>There are some special considerations for running the IBM<sup>®</sup> Toolbox for Java™
|
||
|
|
classes on the IBM Developer
|
||
|
|
Kit for Java (i5/OS™) Java virtual machine (JVM).</p>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Command call</h4><p>Two common ways to call a command are
|
||
|
|
to use one of the following:</p>
|
||
|
|
<ul><li>The IBM Toolbox
|
||
|
|
for Java CommandCall
|
||
|
|
class</li>
|
||
|
|
<li>The java.lang.Runtime.exec method</li>
|
||
|
|
</ul>
|
||
|
|
<p>The <a href="cmdc.htm#cmdc">CommandCall</a> class generates
|
||
|
|
a list of messages that are available to the Java program once the command completes.
|
||
|
|
This list of messages is not available through java.lang.Runtime.exec().</p>
|
||
|
|
<p>The
|
||
|
|
java.lang.Runtime.exec method is portable across many platforms, so if your
|
||
|
|
program must access files on different types of servers, java.lang.Runtime.exec()
|
||
|
|
is a better solution.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Integrated file system</h4><p>Common ways to access a file
|
||
|
|
in the integrated file system of the iSeries™ server:</p>
|
||
|
|
<ul><li>The IFSFile classes of the IBM Toolbox for Java licensed program</li>
|
||
|
|
<li>The file classes that are a part of java.io</li>
|
||
|
|
</ul>
|
||
|
|
<p>The IBM Toolbox
|
||
|
|
for Java <a href="ifs.htm#ifs">integrated file system</a> classes have the advantage
|
||
|
|
of providing more function than the java.io classes. The IBM Toolbox for Java classes
|
||
|
|
also work in applets, and they do not need a method of redirection (such as iSeries Access
|
||
|
|
for Windows<sup>®</sup>)
|
||
|
|
to get from a workstation to the server.</p>
|
||
|
|
<p>The java.io classes are portable
|
||
|
|
across many platforms, which is an advantage. If your program must access
|
||
|
|
files on different types of servers, java.io is a better solution.</p>
|
||
|
|
<p>If
|
||
|
|
you use java.io classes on a client, you need a method of redirection (such
|
||
|
|
as the iSeries Access
|
||
|
|
for Windows)
|
||
|
|
to get to the server file system.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">JDBC</h4><p>Two IBM-supplied JDBC drivers are available
|
||
|
|
to programs running on the i5/OS JVM:</p>
|
||
|
|
<ul><li>The IBM Toolbox
|
||
|
|
for Java JDBC
|
||
|
|
driver</li>
|
||
|
|
<li>The IBM Developer
|
||
|
|
Kit for Java JDBC driver</li>
|
||
|
|
</ul>
|
||
|
|
<p>The IBM Toolbox
|
||
|
|
for Java <a href="jdbc.htm#jdbc">JDBC</a> driver is best to use when the program is
|
||
|
|
running in a client/server environment.</p>
|
||
|
|
<p>The IBM Developer Kit for Java JDBC
|
||
|
|
driver is best to use when the program is running on an iSeries server.</p>
|
||
|
|
<p>If
|
||
|
|
the same program runs on both the workstation and the server, you should load
|
||
|
|
the correct driver through a system property instead of coding the driver
|
||
|
|
name into your program.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section"><h4 class="sectiontitle">Program call</h4><p>Two common ways to call a program are
|
||
|
|
as follows:</p>
|
||
|
|
<ul><li>The ProgramCall class of the IBM Toolbox for Java</li>
|
||
|
|
<li>Through a Java Native Interface (JNI) call</li>
|
||
|
|
</ul>
|
||
|
|
<p>The <a href="pgmc.htm#pgmc">ProgramCall</a> class of the IBM Toolbox
|
||
|
|
for Java licensed
|
||
|
|
program has the advantage that it can call any iSeries server program.</p>
|
||
|
|
<p>You may
|
||
|
|
not be able to call your iSeries server program through JNI. An advantage
|
||
|
|
of JNI is that it is more portable across server platforms.</p>
