This guide concerns the use of the Java technology, which, particularly in terms of RAM memory consumption, is incompatible with the constraints of the shared hosting offers. Java applications are often resource-intensive, which can affect the performance and stability of servers shared among multiple users.

Limited support for client-side applets

Only client-side Java applets, i.e., those executed in the user's web browser, are supported by shared servers. These applets do not require significant server resources and therefore do not pose the same problems as server-side Java applications. Consequently, no product using server-side Java technology is supported.

Unsupported products and technologies

Here is a non-exhaustive list of specific products and technologies that are not supported on shared servers:

• Apache OFBiz
• Greenstone
• Opentaps
• Compiere (which requires Tomcat)
• Play!
• Solr
• Resin
• Jboss
• Scala
• jftp
• Jakarta EE (formerly Java 2 Platform, Enterprise Edition, or J2EE then Java Platform, Enterprise Edition or Java EE)

This policy ensures optimal performance and fair use of resources for all users of shared servers.
