1 Java Development Environment

This chapter provides information about the Java development environment and related considerations. It includes the following topics:

Installing TimesTen and the JDK

Install and configure TimesTen for your environment, as described in Oracle TimesTen In-Memory Database Installation Guide, and the Java JDK, as described in your Java installation documentation. As you set up a Java development environment, the topics of particular interest in Oracle TimesTen In-Memory Database Installation Guide include the following:

After you have installed and configured TimesTen, create a database DSN as described in "Managing TimesTen Databases" in Oracle TimesTen In-Memory Database Operations Guide. The topics of particular interest include the following:

Setting the environment for Java development

Before you begin developing Java applications for TimesTen, you must set your environment appropriately. This includes setting the environment variables appropriately. See "Java environment variables" in Oracle TimesTen In-Memory Database Installation Guide for more information about environment variables for Java, including discussion of the PATH, CLASSPATH, THREAD_FLAGS, and shared library path environment variables.

Environment variables and runtime access to the Instant Client are configured through the appropriate ttenv script See "Environment variables" in the Oracle TimesTen In-Memory Database Installation Guide for additional information.

Note:

TimesTen includes Oracle Instant Client, which is required for certain JDBC features and operations.

Compiling Java applications

"Java environment variables" in Oracle TimesTen In-Memory Database Installation Guide discusses the CLASSPATH setting for compiling Java applications in TimesTen.

Compiling any Java application requires the JAR file appropriate for your JDK to be in your classpath. In TimesTen, the following are for JDK 5.0 and JDK 6, respectively:

install_dir/lib/ttjdbc5.jar
install_dir/lib/ttjdbc6.jar

In addition, compiling any JMS/XLA application requires the following to be in your classpath:

install_dir/lib/timestenjmsxla.jar
install_dir/3rdparty/jms1.1/lib/jms.jar
install_dir/lib/orai18n.jar

About the TimesTen Java demos

After you have configured your Java environment, you can confirm that everything is set up correctly by compiling and running the TimesTen Quick Start demo applications. Refer to the Quick Start welcome page at install_dir/quickstart.html, especially the links under SAMPLE PROGRAMS, for information about the following:

Note:

All of the level demos support both direct and client/server connections to the database.
