<div><div class="section"><p>Before
|
||
|
|
moving the IBM<sup>®</sup> <span class="keyword">i5/OS™</span> PASE native method for Java™ example
|
||
|
|
to your iSeries™
|
||
|
|
server, you need to compile the source code, create a C include file, and
|
||
|
|
create a shared library object.</p>
|
||
|
|
<p>The example includes the following
|
||
|
|
C and Java source
|
||
|
|
files:</p>
|
||
|
|
<ul><li><strong>PaseExample1.c:</strong> C source code file that contains an implementation
|
||
|
|
of getStringNative(). </li>
|
||
|
|
<li><strong>PaseExample1.java:</strong> Java source code file that calls the
|
||
|
|
native getStringNative method in the C program.</li>
|
||
|
|
</ul>
|
||
|
|
<p>You use the compiled Java .class file to create a C include file,
|
||
|
|
PaseExample1.h, which contains a function prototype for the getStringNative
|
||
|
|
method contained in the C source code.</p>
|
||
|
|
<p>To prepare the example source
|
||
|
|
code on your AIX<sup>®</sup> workstation,
|
||
|
|
complete the following steps:</p>
|
||
|
|
<ol><li>Use the following command to compile the Java source code: <pre> javac PaseExample1.java</pre>
|
||
|
|
|
||
|
|
</li>
|
||
|
|
<li>Use the following command to create a C include file that contains the
|
||
|
|
native method prototypes: <pre> javah -jni PaseExample</pre>
|
||
|
|
|
||
|
|
The new C include file (PaseExample1.h) contains a function prototype for
|
||
|
|
the getStringNative method. The example C source code (PaseExample1.c)
|
||
|
|
already includes the information you would copy and modify from the C
|
||
|
|
include file to use the getStringNative method. For more information
|
||
|
|
about using JNI, see the <a href="http://java.sun.com/docs/books/tutorial/native1.1/index.html" target="_blank">Java Native Interface tutorial</a> on the Sun
|
||
|
|
Web site.</li>
|
||
|
|
<li>Use the following command to compile the C source code and create a shared
|
||
|
|
library object. <pre> xlc -G -I/usr/local/java/J1.3.0/include PaseExample1.c -o libPaseExample1.so</pre>
|
||
|
|
|
||
|
|
The new shared library object file (libPaseExample1.so) contains the native
|
||
|
|
method library "PaseExample1" that the example uses. <p><strong>Note:</strong> You
|
||
|
|
may need to change the -I option to point to the directory that contains
|
||
|
|
the correct Java native method include files (for example,
|
||
|
|
jni.h) for your AIX system.</p>
