In order to use your Talend product, Java must be installed on your machine. If you install your Talend Studio using the Talend Studio Installer, you do not need to set up a Java Environment as it is embedded in the Installer.

These pages list:

Compatible Java environments

Note

In the following documentation:

  • recommended: designates an environment recommended by Talend based on our experiences and customer usage;

  • supported: designates a supported environment for use with the listed component or service;

  • supported with limitations: designates an environment that is supported by Talend but with certain conditions explained in notes.

These tables provide a summary of the supported Java Runtime environments.

In this table:

  • (R) means that this combination is recommended;

  • means that this combination is supported;

  • means that this combination is not supported.

Note that only the 64-bit versions of the compatible Java Runtime environments are supported.

The Compiler Compliance Level corresponds to the Java version used for the Job code generation. This option can be changed in the project settings of the Studio. For more information, see Talend Studio User Guide.

Note

All Talend products and associated third-party applications, such as the Hadoop cluster, should use the same Java version for compliance. Before you install or upgrade any associated third-party application, Talend recommends that you check with java version they support.

For more information on Java specificities (version, Operating Systems compatibility), see Talend Help Center and Talend Community.

Setting up JAVA_HOME

In order for your Talend product to use the Java environment installed on your machine, you must set the JAVA_HOME environment variable.

To do so, proceed as follows:

  1. Find the folder where Java is installed, usually C:\Program Files\Java\JREx.x.x.

  2. Open the Start menu and type Environment variable in the search bar to open the Environment variable properties.

  3. Click Environment Variables....

  4. Under System Variables, click New... to create a variable. Name the variable JAVA_HOME, enter the path to your Java JRE, and click OK.

  5. Under System Variables, select the Path variable, click Edit... and add the following variable at the end of the Path variable value:

    ;%JAVA_HOME%\bin
