If you choose to install this for your own service be aware that it will be deprecated in the near future.

The command to do the shut down will be web server specific. See the documentation for your web server for information on how to do this. There may be many alternatives.

If you see the Enterprise Vocabulary Services "Welcome to LexEVS" web page then you have successfully installed the LexEVS Distributed. Congratulations!
...
- If the Local Runtime environment is properly installed and tested then the Distributed environment should have few problems.
- If you receive deployment errors in JBoss and are unable to see the EVS home page then you may not have configured the properties attribute in JBoss's properties-service.xml.
- You may also need to adjust the path in lexevs.properties where lbconfig.props location is defined.
- We recommend no threading limits less than 512mb being applied when starting JBoss. (These would usually be configured as a JAVA_OPTS variable in a run.conf or similar file and would be set as follows: -Xss512M )
- We recommend a minimum heap size of -Xmx750m when starting JBoss and about 1000m per million entities loaded. (Also a JAVA_OPTS variable)
We recommend a minimum Perm Gen size of 256m.
