Java - 6.2

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.

The information contained in the following table is applicable for the 6.2.2 version of your Talend product at the time of its release. For updated information on the latest supported software or databases, see this page.

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

In this table:

(R) means that this combination is recommended;

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

For more information on Java specificities (version, Operating Systems compatibility), see the Knowledge Base articles on Talend Help Center.

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:

Find the folder where Java is installed, usually /Library/Java/Home.
Open a terminal.
Use the export command to set the JAVA_HOME and Path variables.
For example:
```
export JAVA_HOME=/usr/lib/jvm/jre1.8.0_65
export PATH=$JAVA_HOME/bin:$PATH
```
Add these lines at the end of the global profiles in the /etc/profile file or in the user profiles in the ~/.profile file.
After changing one of these files you have to log on again.
