|
|
<div><p>Before you write and deploy your JDBC applications, you may need
|
|
to include specific jar files in your classpath.</p>
|
|
<div class="section"><h4 class="sectiontitle">Core JDBC</h4><p>For core Java™ Database Connectivity (JDBC) access
|
|
to the local database, there are no requirements. All support is built in,
|
|
preinstalled, and configured.</p>
|
|
</div>
|
|
<div class="section"><h4 class="sectiontitle">JDBC 2.0 optional package</h4><p>If you need to use the
|
|
classes of the JDBC 2.0 optional package, you must include the jdbc2_0-stdext.jar
|
|
file in your classpath. This Java ARchive (JAR) file contains all the
|
|
standard interfaces that you need to write your application to use the JDBC
|
|
2.0 optional package. To add the JAR file to your extensions classpath, create
|
|
a symbolic link from the UserData extensions directory to the location of
|
|
the JAR file. You only need to perform this once; the JAR file in the JDBC
|
|
2.0 optional package is always available to your applications at runtime.
|
|
Use the following command to add the optional package to the extensions classpath:</p>
|
|
<pre> ADDLNK OBJ('/QIBM/ProdData/OS400/Java400/ext/jdbc2_0-stdext.jar')
|
|
NEWLNK('/QIBM/UserData/Java400/ext/jdbc2_0-stdext.jar')</pre>
|
|
<p><strong>Note:</strong> This
|
|
requirement is only for J2SDK 1.3. Since J2SDK 1.4 is the first release with
|
|
JDBC 3.0 support, all of JDBC (that is, the core JDBC and the optional package)
|
|
moves into the base J2SDK runtime JAR file that your program always finds.</p>
|
|
</div>
|
|
<div class="section"><h4 class="sectiontitle">Java Transaction API</h4><p>If you need to use the Java Transaction
|
|
API (JTA) in your application, you must include the jta-spec1_0_1.jar file
|
|
in your classpath. This JAR file contains all the standard interfaces that
|
|
you need to write your application to use JTA. To add the JAR file to your
|
|
extensions classpath, create a symbolic link from the UserData extensions
|
|
directory to the location of the JAR file. This is a one-time operation and
|
|
once completed, the JTA JAR file is always available to your application at
|
|
runtime. Use the following command to add JTA to the extensions classpath:</p>
|
|
<pre> ADDLNK OBJ('/QIBM/ProdData/OS400/Java400/ext/jta-spec1_0_1.jar')
|
|
NEWLNK('/QIBM/UserData/Java400/ext/jta-spec1_0_1.jar')</pre>
|
|
</div>
|
|
<div class="section"><h4 class="sectiontitle">JDBC compliance</h4><p>The native JDBC driver is compliant
|
|
with all relevant JDBC specifications. The compliance level of the JDBC driver
|
|
is not dependent on the <span class="keyword">i5/OS™</span> release,
|
|
but on the JDK release you use. The native JDBC driver's compliance level
|
|
for the various JDKs is listed as follows:</p>
