Overview

The spring framework has emerged over the last few years as a versatile and efficient support structure for multiple types of Java applications. The MVC component facilitates the development of rich web-driven applications. The SpringSource tool suite(STS) is an Eclipse derivative software package bundling the necessary tools to develop efficiently with the Spring framework. The Spring 3 MVC project is a Maven compliant project and the guide will make use of it to include a LexEVS dependency.

This guide will illustrate how to use a local instance of LexEVS in a Spring 3.0.x MVC project and how to deploy it to a Tomcat 6 server from within STS. It was tested using LexEVS 6.0 and Windows 7. This should be applicable to other environments and future versions of LexEVS, but some parameters, especially paths, might need to be formatted differently.

This guide will NOT explore how to leverage LexEVS programatically or how to best develop with the Spring framework. The reader is invited to explore the multiple resources on the web that can help in this endeavor.

Prerequisites

You will need internet access to complete this guide.

LexEVS Local Runtime Install

Please follow carefully the steps mentioned in the guide for installing LexEVS 6.0 Local Runtime.

Once all the steps have been followed successfully you should have a functional LexEVS Local Runtime instance.

In order to facilitate subsequent testing, please load and activate the test terminology Automobiles.xml located in the folder {LEXEVS_HOME}\test\resources\testData\Automobiles.xml

Verification

Select the [textlex] folder project in the package explorer window then click on play button or click on the menu "Run" -> Run
The next window will ask you how you want to run the project. Select "Run on server".
In the list on the next window, you should see the "Tomcat v6.0 Server at localhost" entry that you created earlier. Select it and check the box "Always use this server..."
Click Next, then click Finish.
You should then see the "Hello world!" page with the current time on it.
You now have a functioning Spring 3 MVC project.

Adding LexEVS as a Maven Dependency

The Spring 3 MVC project being a Maven compliant project, we will add LexEVS as dependency. It is not available in a public repository so we will need to install in our local repository first.

Downloading the Required Files

You will need four files to successfully add LexEVS as a dependency.

LexEVS jar: Can be found in your local LexEVS install: {LEXEVS_HOME}\runtime-components\lexbig.jar

...

- For easier access,

...

Adjusting Scope of JUnit

LexEVS currently uses JUnit during runtime. This is a bit unusual and might change in a future release but for now, it needs to be adjusted.

Select the project folder [testlex] in the Package Explorer view and unfold it.
Double click on the pom.xml file to open it.
Select the Dependencies tab at the bottom of the window.
In the Dependencies pane, scroll down in the dependencies selectbox and click once on junit. On the right side, the Dependency Details area should present a scope which is "test" in the combobox.
Change it to compile.
Click on menu File -> Save or press Ctrl-s.

Including LexEVS in the MVC Project

Select the [textlex] project. Right-click on it and select Maven -> Add Dependency from the context menu.
Enter lexevs in the first textbox.
The search results should show: lexevs lexevs
Select it and click ok.
STS will now download all the dependencies needed to work with LexEVS. You can follow the progress in the progress view (tab).

Creating a Test File

Select and unfold the project folder [textlex] in the package explorer.
Navigate to src/test/java. You should see an empty package [org.test.test]
Right-click on it and select New -> JUnit Test Case
Put the name of your test in the name textbox. We will name it LexBigConnect. Click on Finish.

Copy this in the file (including the last bracket):

Code Block
package org.test.test; import static org.junit.Assert.*; import org.LexGrid.LexBIG.Exceptions.LBInvocationException; import org.LexGrid.LexBIG.Impl.LexBIGServiceImpl; import org.LexGrid.LexBIG.LexBIGService.LexBIGService; import org.LexGrid.LexBIG.DataModel.InterfaceElements.CodingSchemeRendering; import org.junit.Test; public class LexBigConnect { @Test public void test() throws LBInvocationException { LexBIGService lbSvc = LexBIGServiceImpl.defaultInstance(); System.out.println("The currently active terminologies are:"); for(CodingSchemeRendering csr : lbSvc.getSupportedCodingSchemes().getCodingSchemeRendering()) System.out.println(csr.getCodingSchemeSummary().getFormalName()); assertTrue(true); } }

Code Block

package org.test.test;

import static org.junit.Assert.*;

import org.LexGrid.LexBIG.Exceptions.LBInvocationException;
import org.LexGrid.LexBIG.Impl.LexBIGServiceImpl;
import org.LexGrid.LexBIG.LexBIGService.LexBIGService;
import org.LexGrid.LexBIG.DataModel.InterfaceElements.CodingSchemeRendering;

import org.junit.Test;

public class LexBigConnect {

    @Test
    public void test() throws LBInvocationException {

        LexBIGService lbSvc = LexBIGServiceImpl.defaultInstance();
        System.out.println("The currently active terminologies are:");
        for(CodingSchemeRendering csr : lbSvc.getSupportedCodingSchemes().getCodingSchemeRendering())
            System.out.println(csr.getCodingSchemeSummary().getFormalName());

        assertTrue(true);

Running the Project

Select the project [textlex] in the Package Explorer.
Select the menu Run -> Run. Select "Run on Server" then click OK.
You should see the home page displayed with the date/time and, on the last line, the name of one of your active terminology in LexEVS.
You now have a functional Spring 3 MVC project interacting successfully with a local instance of LexEVS.
