Informix JDBC Driver Programmer's Guide Getting Started

To use 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.

There are two ways of setting your CLASSPATH environment variable:

• Add the full pathname of the ifxjdbc.jar file to the CLASSPATH environment variable, as shown in the following example:
setenv CLASSPATH /work/jdbcdriver_home/lib/ifxjdbc.jar:$CLASSPATH

To use the version of the driver that supports debugging, specify the file ifxjdbc-g.jar instead of ifxjdbc.jar.

• Unpack the ifxjdbc.jar file and add its directory to the CLASSPATH environment variable, as shown in the following example:
cd /work/jdbcdriver_home/lib
jar xvf ifxjdbc.jar
setenv CLASSPATH /work/jdbcdriver_home/lib:$CLASSPATH

To use the version of the driver that supports debugging, specify the file ifxjdbc-g.jar instead of ifxjdbc.jar.

There are two ways of setting your CLASSPATH environment variable:

• Add the full pathname of the ifxjdbc.jar file to the CLASSPATH environment variable, as shown in the following example:
set CLASSPATH=c:\work\jdbcdriver_home\lib\ifxjdbc.jar;%CLASSPATH%

To use the version of the driver that supports debugging, specify the file ifxjdbc-g.jar instead of ifxjdbc.jar.

• Unpack the ifxjdbc.jar file and add its directory to the CLASSPATH environment variable, as shown in the following example:
cd c:\work\jdbcdriver_home\lib
jar xvf ifxjdbc.jar
set CLASSPATH=c:\work\jdbcdriver_home\lib;%CLASSPATH%

To use the version of the driver that supports debugging, specify the file ifxjdbc-g.jar instead of ifxjdbc.jar.
