Hessian

System Message: WARNING/2 (line 22)

Explicit markup ends without a blank line; unexpected unindent.

Wikitty provides the modules necessary to be used as a client/server based on Hessian.

It is compounded of :

  • a war application that, reading a configuration file, is capable of providing a service on any Wikitty storage type.

  • a Factory that returns a proxy on a distant service.

Server

The server is available as a a web app (war) ready to be used. You can download it on this adress : http://www.nuiton.org/projects/wikitty/files

By default, this web app is based on the configuration file /etc/wikitty-hessian.properties (under Linux). This configuration file contains 3 configuration options specific to Hessian :

  • wikitty.hessian.usecache : add cache use

  • wikitty.hessian.usenotification : add notification use

  • wikitty.hessian.usesecurity : add security use

Then the configuration file contains the specific configuration of the storage to use.

Here is a configuration example:

# security
wikitty.hessian.usesecurity=true
wikitty.service.login=xxxx
wikitty.service.password=zzzz

# notification
wikitty.hessian.usenotification=true
wikitty.service.event.jgroupschannelname=myjgroupchannel
wikitty.service.event.propagateEvent=false

# cache
wikitty.hessian.usecache=true
wikitty.service.cache.listenevents=true

# solr configuration
solr.data.dir=/var/lib/myapp/solr

The application is then accessible on "/wikitty" uri following the deployment context. For example : http://localhost:8080/myapp/wikitty

Client

The interface for the service can be obtained using the available Factory in wikitty-hessian-client module.

Example:

WikittyService service = getWikittyService("http://localhost/wikitty");

The service can then be used as a local service.
