Introduction

This section provides requirements, instructions, and troubleshooting information for installing the LexEVS Distributed environment.

Preliminary Considerations

Once you have completed the additional prerequisite software install, the Distributed environment install steps, and the verification test as described in this guide then you should be ready to start using the Distributed features to meet the needs of your application. Not counting prerequisite software products the installation and verification should not take more than 30 minutes.

Downloading and Installing LexEVS Distributed

Step

Action

1. Download the latest version of the LexEVS Distributed WAR file from the right. You have a choice between WAR files tailored for JBoss or Apache Tomcat installations. The location you have chosen to save this on your computer will be referred to as the SAVE_DIRECTORY. Our command examples will use scratch as this directory.

Info
titleNote

Access to the downloads does not require an account. If you are having trouble downloading files then you may need to disable pop-up blockers or check any firewall settings at your site.

2. Shut down your application or servlet container. This presumes that you have already installed a web server as outlined in the LexEVS 6.0 Prerequisite Software Supported to Include. 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.
JBoss example:

  • Windows:
    Code Block
    
    {{shutdown.bat -S}}
    

...

  • Unix:

...

  • Code Block

...

  • 
    {{./shutdown.sh -S}}
    

...

  • If

...

  • you

...

  • experience

...

  • Java

...

  • errors

...

  • then

...

  • the

...

  • server

...

  • may

...

  • already

...

  • be

...

  • down.

3. Rename the WAR file. These files are distributed with an application server designation in their name for clarity while downloading them.
Change to the SAVE_DIRECTORY and rename the file, like this:

Code Block

rename {SAVE_DIRECTORY}/lexevsapi6.0.{WEB_SERVER}.war {SAVE_DIRECTORY}/lexevsapi60.war

...

JBoss

...

example:

...

  • Windows:

...


  • Code Block
    
    rename c:\scratch\lexevsapi60.jboss.war lexevsapi60.war
    

...

  • Unix:

...


  • Code Block
    
    move /scratch/lexevsapi60.jboss.war lexevsapi60.war
    

...

  • Info
    titleNote

    Consider other names as well. Many application servers use the deployed name as part of the URL, so if you would rather it be a different name then you should rename the WAR file to that.

4. Copy the WAR file to the appropriate web application server directory, like this:

Code Block

copy {SAVE_DIRECTORY}\lexevsapi60.war {WEB_SERVER_HOME}\{DEPLOYMENT_HOME}

...

...where

...

SAVE_DIRECTORY

...

is

...

the

...

location

...

of

...

the

...

downloaded

...

file.

...


WEB_SERVER

...

is

...

the

...

brand

...

of

...

the

...

web

...

server.

...


WEB_SERVER_HOME

...

is

...

your

...

application

...

server

...

home

...

directory.

...


DEPLOYMENT_HOME

...

is

...

the

...

Web

...

Archive

...

deployment

...

directory

...

for

...

your

...

application

...

server.

...


JBoss

example:

...

  • Windows:

...

  • Code Block

...

  • 
    copy c:\scratch\lexevsapi60.war c:\jboss-5.1.0.GA\server\default\deploy
    

...

  • Unix:

...

  • Code Block

...

  • 
    copy /scratch/lexevsapi60.war /jboss-4.0.5.GA/server/default/deploy

...

...

to

...

set

the

of

the

LexEVS

...

configuration.

6. (OPTIONAL)

...

The

...

lexevs.properties

...

file

...

is

...

also

...

used

...

to

...

add

...

security

...

for

...

any

...

coding

...

scheme.

...

This

...

is

...

not

...

a

...

highly

...

used

...

function,

...

but

...

may

...

be

...

required

...

if

...

your

...

service

...

is

...

publicly

...

hosting

...

a

...

proprietary

...

terminology.

...

For

...

each

...

coding

...

scheme

...

a

...

security

...

implementation

...

class

...

name

...

can

...

be

...

set

...

to

...

enable

...

security

...

like

...

this:

...

Code Block

...


{CODING_SCHEME_NAME}={SECURITY_IMPLEMENTATION}

...

...where

...

CODING_SCHEME_NAME

...

is

...

the

...

name

...

or

...

URI

...

of

...

the

...

terminology.

...


SECURITY_IMPLEMENTATION

...

is

...

a

...

class

...

that

...

implements

...

the

...

interface

...

gov.nih.nci.system.dao.security.DAOSecurity.

...


For

...

all

...

ways

...

of

...

accessing

...

the

...

coding

...

scheme,

...

security

...

must

...

be

...

set

...

up.

,

...

but

others

...

are

...

possible

...

too.Note:Coding

...

schemes

...

can

...

be

...

added

...

or

...

changed

...

later

...

after

...

a

...

coding

...

scheme

...

or

...

terminology

...

is

...

loaded

...

into

...

LexEVS.

Testing LexEVS Distributed

Step

Action

1. Start your application or servlet container if it is not already started. The start command will be web server specific. See the documentation for your web server for information on how to do this.
JBoss example:

  • Windows:
    Code Block
    
    Run.bat \-c default
    

...

  • Unix:

...

  • Code Block

...

  • 
    ./Run.sh \-c default

...

  • 
    

Image Added

2. Verify the installation by opening a browser to:

Code Block

http://{SERVER_ADDRESS}/{WAR_FILE_DEPLOYED}

...

...

...

where

...

SERVER_ADDRESS

...

is

...

the

...

address

...

of

...

your

...

server

...

(domain

...

and

...

optionally

...

the

...

port

...

number).

...


WAR_FILE_DEPLOYED

...

is

...

the

...

name

...

of

...

the

...

WAR

...

file

...

you

...

placed

...

in

...

the

...

server

...

directories

...

for

...

deployment.

...


For

...

example:

Code Block

...

http://localhost:8080/lexevsapi60

...


If

...

you

...

are

...

using

...

localhost

...

then

...

your

...

browser

...

must

...

be

...

running

...

on

...

the

...

same

...

server

...

as

...

LexEVS.

If you see the Enterprise Vocabulary Services "Welcome to LexEVS" web page then you have successfully installed the LexEVS Distributed. Congratulations!

Troubleshooting

  • 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

  • entities

...

  • loaded.

...

  • (Also

...

  • a

...

  • We

  • recommend

...

  • a

...

  • minimum

...

  • Perm
