Introduction

This document is a section of the Installation Guide.

This section provides requirements, instructions, and troubleshooting information for installing LexEVS Grid Services.

Preliminary Considerations

  • Just like the Remote API install, it is not required that you load a terminology into the Local Runtime in order to complete the installation of the Grid Services environment. However, the Grid services are not very useful if they have nothing in the underlying Local Runtime to query against.

Once you have completed the Grid Services environment install steps and the verification test as described in this guide then you should be ready to start using the Grid Services 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 the LexEVS Data or Analytical Grid Services

Step

Action

1. Download the latest version of the LexEVS Analytical or Data Services ZIP file from the right. You have a choice between ZIP 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. Unzip the file or files you have downloaded to SAVE_DIRECTORY.

Warning
titleWarning

Each ZIP contains a file by the same name. This is by design because you can not deploy the Data or Analytical Grid Services to the same server. Therefore you must do these one at a time or unzip them to multiple locations.

Info
titleNote

Windows typically understands ZIP files and can extract files. Unix has an unzip command. Other utilities can be used such as WinZip or 7-Zip.

3. Shut down your application or servlet container. This presumes that you have already installed a web server as outlined in the Prerequisite Software. 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:
    shutdown.bat -S
  • Unix:
    ./shutdown.sh -S
    If you experience Java errors then the server may already be down.

4. Create a directory for the web archive.
Create a directory called wsrf.war inside the following directory:

...
WEB_SERVER_HOME

 5. Unzip the wsrf.war file to the wsrf.war directory.
