JEM is a Java application: it runs on Java Runtime Environment (JRE) version 6 or 7. It has been tested on Oracle Java SE 6 and 7 and on OpenJDK 6.
It's not a pure Java application because it's using Hyperic SIGAR framework to gather CPU/Memory consumptions (for both jobs and node). Furthermore, JEM creates always new process to execute jobs and for this reason it's current complaint with all UNIX systems (BASH shell is needed) and Windows.
To persist JEM information, a MySql instance is necessary. IBM DB2 and ORACLE are also supported (see persistence configuration).
The platform compatibility is the following:
| Operating system | Architecture | Versions |
|---|---|---|
| Linux | x86 | 2.2, 2.4, 2.6 kernels |
| Linux | amd64 | 2.6 kernel |
| Linux | ppc | 2.6 kernel |
| Linux | ppc64 | 2.6 kernel |
| Linux | ia64 | 2.6 kernel |
| Windows | x86 | NT 4.0, 2000 Pro/Server, 2003 Server, XP, Vista, 2008 Server, 7 |
| Windows | x64 | 2003 Server, Vista, 2008 Server, 7 |
| Solaris | sparc-32 | 2.6, 7, 8, 9, 10 |
| Solaris | sparc-64 | |
| Solaris | x86 | 8, 9, 10 |
| Solaris | x64 | |
| AIX | ppc | 4.3, 5.1, 5.2, 5.3, 6.1 |
| AIX | ppc64 | 5.2,5.3,6.1 |
| HP-UX | PA-RISC | 11 |
| HP-UX | ia64 | 11 |
While Hyperic SIGAR only depends on the Linux kernel version, the following distributions have been certified:
| Distribution | Versions |
|---|---|
| Red Hat | 6.2, 7.3, 8.0, 9.0 |
| RHEL | 3, 4, 5, 6 |

JEM, on web site, is a pure Java application: it runs on Java Runtime Environment (JRE) version 6 or higher. It has been tested Oracle Java SE 6 and 7 and on OpenJDK 6.
It has been tested on Apache Tomcat version 6 and 7 and on Jetty.
No restrictions to use in another servlet container or application server.
JEM user interface is developed on GWT framework and it's using CSS3.
