Delft-FEWS 2017.02 | No JMS provider required anymore. Direct database access (DDA) is replacing synchronisation via JMS. Https (as supported by JMS) is not supported. | |||
Delft-FEWS 2017.01 | ActiveMQ 5.14.5 | Java JRE 8 |
64 bit (installation of 32 bit is not recommended) | ActiveMQ 5.14.5 requires JRE 8 (best 64 bit), but may also be used with JRE 7. |
Delft-FEWS 2016.02 and older | ActiveMQ 5.11.1 | ActiveMQ 5.11 requires JRE 8 (best 64 bit), but may also be used with JRE 7. | ||
Delft-FEWS 2017.01 and older | JBoss 4 / 5 / 7 | Java JRE 6 / 7 | Does not function with JRE 8. Note that JBoss4 requires a jdbc driver for storing temporary messages. The JRE version with which this driver is compiled should be compatible with the JRE used for Jboss4. |
