Using the driver in an application

To use HCL Informix® JDBC Driver in an application, you must set your CLASSPATH environment variable to point to the driver files. The CLASSPATH environment variable tells the Java™ virtual machine (JVM) and other applications where to find the Java class libraries used in a Java program.

UNIX

There are two ways to set your CLASSPATH environment variable:

Add the full path name of ifxjdbc.jar to CLASSPATH:

setenv CLASSPATH /jdbcdriv/lib/ifxjdbc.jar:$CLASSPATH

To add localized message support, specify ifxlang.jar:

setenv CLASSPATH 
/jdbcdriv/lib/ifxjdbc.jar:/jdbcdriv/lib/ifxlang.jar:
   $CLASSPATH

Unpack ifxjdbc.jar and add its directory to CLASSPATH:

cd /jdbcdriv/lib
jar xvf ifxjdbc.jar
setenv CLASSPATH /jdbcdriv/lib:$CLASSPATH

To add localized message support, specify ifxlang.jar:

cd /jdbcdriv/lib
jar xvf ifxjdbc.jar
jar xvf ifxlang.jar
setenv CLASSPATH /jdbcdriv/lib:$CLASSPATH

Windows

There are two ways to set your CLASSPATH environment variable:

Add the full path name of ifxjdbc.jar to CLASSPATH:

set CLASSPATH=c:\jdbcdriv\lib\ifxjdbc.jar;%CLASSPATH%

To add localized message support, specify ifxlang.jar:

set CLASSPATH=c:\jdbcdriv\lib\ifxjdbc.jar;c:\
   jdbcdriv\lib\ifxlang.jar;%CLASSPATH%

Unpack ifxjdbc.jar and add its directory to CLASSPATH:

cd c:\jdbcdriv\lib
jar xvf ifxjdbc.jar
set CLASSPATH=c:\jdbcdriv\lib;%CLASSPATH%

To add localized message support, specify ifxlang.jar:

cd c:\jdbcdriv\lib
jar xvf ifxjdbc.jar
jar xvf ifxlang.jar
set CLASSPATH=c:\jdbcdriv\lib;%CLASSPATH%

If you are using javax.sql classes (for example, Datasource), specify ifxjdbcx.jar in addition to ifxjdbc.jar.
