Only if you wish to download the ECaccess Gateway package, please first register at the ECaccess Registration Centre:

If you are to perform the administrative task of installing and/or maintaining the ECaccess software, you should study the Administrator's Manual.

The minimum requirement for the latest Gateway package is Java11, however we recommend installing the latest GraalVM Community edition available at the following URL:

The Gateway software is currently running at ECMWF using the GraalVM Community 22.2 (Java17) on Rocky Linux 8:

  • OpenJDK 17.0.4 2022-07-19
  • OpenJDK Runtime Environment GraalVM CE 22.2.0 (build 17.0.4+8-jvmci-22.2-b06)
  • OpenJDK 64-Bit Server VM GraalVM CE 22.2.0 (build 17.0.4+8-jvmci-22.2-b06, mixed mode, sharing)

Although it should work with any release of Java 11+ please note we have only tested the Gateway with OpenJDK 17.0.4 2022-07-19 and OpenJDK 11.0.16 2022-07-19.

Also, refer to the Administrator's Manual for further details.

Warning: please make sure the ECACCESS_HOME path in the "gateway" script does not include any symbolic links as it might prevent the Http Plugin from accessing its configuration files. You can get the real path without symbolic links with the "realpath" command.


Please note the following package requires at least Java11 to be installed.

ECaccess gateway package v6.3.1 (Java11+)
