2. Reminder about JBoss
JBoss AS is the free version of JBoss (whereas JBoss EAP is the entreprise version)
JBoss 5 is the last stable release of JBoss AS
JBoss 7 introduces a brand new architecture, with a complete rewriting of the engine.
From JBoss 8, JBoss AS was renamed to “WildFly”

3. Reminder on MamboWEB architecture
The applications reach TANGO via Internet thanks to 3 jars:
WebTangORB : Module to get data
WebLauncher : starts application on client side
TangORBServer : Tango Web Server.
PROS
No modification are to be done on the application side to make it available through the WEB
CONS
Rely on the availability of a JVM on the client side
TANGO WEB
WebTangORB.jar
COMETE API
TangORB.jar
MachineStatusWEB.jar
MamboWEB.jar
TangORBServer.war
Server
Client
WebLauncher.jar

4. Current state of Web architecture at SOLEIL
Server side (TangoWebServer) :
JBoss AS GA
TangORB 9 / Java6
Client Side (WebTangORB):
Apache httpd
TangORB9 / Java6
32 bits RedHat 4
TangoWeb is mainly used for MamboWeb (for users who need to access the machine archived data without being in the control room)

5. Problems
JBoss 4 is obsolete, no more supported, and is not guarranted to be compatible with java 7 and further versions
JBoss 4 has strong lacks in performances and is difficult to maintain
Java 6 is completely obsolete, and Java 7 is already replaced by Java 8
Java 8 (and latests releases of Java 7) are not compatible with old OS like Redhat 4
MamboWeb/WebTangORB is not realy compatible with alternative devices, like smartphones

6. Proposals
Step 1: Migrate to more recent versions of JBoss (Wildfly 10 ?)
Step 2 : Think about alternative implementations of both server and client solutions
Server side: latest EJB ?
Client side: HTML5 version ?
Collaboration with ELETTRA or any institute interested in such a solution
Choose common libraries

7. Conclusion
Little efforts were made these last years on the tango web service.
In the meanwhile, Web technologies evoluted and became more and more necessary for facility monitoring.
It is time to get rid of dynosorus solutions
SOLEIL would be happy to share ideas and collaborate on the subject
