Getting started with the Integration
Plug-in for Java
The IBM® SPSS® Statistics - Integration Plug-in for Java enables an application developer to
create Java applications that can invoke and control the IBM® SPSS® Statistics processor, or
to implement extension commands in Java that can then be run from within SPSS Statistics.
Extension commands are SPSS Statistics commands that are implemented in an external language
(Python, R or Java) and allow users who are proficient in that language to share external functions
with users o f standard SPSS Statistics command syntax.
With the Integration Plug-in for Java, you can do the following:
Execute SPSS Statistics command syntax.
Read case data from the active dataset.
Get information about data in the active dataset.
Add new variables a nd append cases to the active dataset.
Get output results from syntax commands.
Create custom output in the form of pivot tables and text blocks.
The Integration Plug-in for Java is installed with SPSS Statistics and SPSS Statistics Server
and requires no separate installation or configuration. For version 21 of SPSS Statistics, the
Integration Plug-in for Java supports Java version 6.
The Integration Plug-in for Java is designed to work with Unicode mode. Use of the Integration
Plug-in for Java with code page mode is not recommended.
Complete documentation for all of the classes and methods available with the Integration
Plug-in for Java is available in the Help system under the heading Integration Plug-in for Java
API Reference.
Invoking IBM SPSS Statistics from an external Java application
The interface for invoking IBM® SPSS® Statistics and controlling the SPSS Statistics processor
is provided in the JAR file spssjavaplugin.jar, which is installed with your SPSS Statistics
product. The JAR file contains the com.ibm.statistics.plugin package, which contains the Java
classes available with the IBM® SPSS® Statistics - Integration Plug-in for Java. Following are
the locations of spssjavaplugin.jar by operating system. Be sure to add spssjavaplugin.jar to
your Java class path.
On W indows, spssjavaplugin.jar is located in the SPSS Statistics installation directory.
