DESCRIPTION:Speakers: KWIATEK\, Michal (CERN)\nOver the last years\, we ha
 ve experienced a growing demand for hosting java web \napplications. At th
 e same time\, it has been difficult to find an off-the-shelf \nsolution th
 at would enable load balancing\, easy administration and a high level of \
 nisolation between applications hosted within a J2EE server.\n\nThe archit
 ecture developed and used in production at CERN is based on a linux \nclus
 ter. A piece of software developed at CERN\, JPSManager\, enables easy man
 agement \nof the service by following the self-management paradigm. JPSMan
 ager also enables \nquick recovery in case of hardware failure. The isolat
 ion between different clients \nof the service is implemented using multip
 le instances of Apache Tomcat\, but the \narchitecture is open and a diffe
 rent J2EE server can be incorporated if necessary. \nThis paper describes 
 this architecture in detail and analyses its advantages and \nlimitations.
  Examples of HEP related applications\, which make use of this\narchitectu
 re\, are also given.\n\nhttp://indico.cern.ch/contributionDisplay.py?contr
