Creating a SOAP Client Project
In this lesson, we will look at how to create a Java project with all the required dependencies for making SOAP web service calls.
We'll cover the following
Installing build tools
Please ensure JDK 8 or JRE 8 is installed on your machine as it is required by both Gradle and Maven.
Gradle
If you have a Macintosh/Linux machine and already have brew
installed, you can just run the following command to install gradle
.
brew install gradle
Else, you can manually install it by downloading the binary from Gradle Latest Release. To download version 6.3
, use this link.
After downloading the .zip
, unzip the archive file.
Macintosh/Linux
Add the following lines in ~/.profile
file
export GRADLE_HOME=<unzipped gradle folder path>
export PATH=$PATH:$GRADLE_HOME/bin
Run the following command:
source ~/.profile
Windows
Run the following commands from the command prompt.
set GRADLE_HOME=<unzipped gradle folder path>
set PATH=%PATH%;%GRADLE_HOME%\bin
Maven
If you have a Macintosh/Linux machine and already have brew
installed, you can just run the following command to install maven
.
brew install maven
Else, you can manually install it by downloading the binary from https://maven.apache.org/download.cgi. To download version 3.6.3
, use this link.
After downloading the .zip
, unzip the archive file.
Macintosh/Linux
Add the following lines in ~/.profile
file
export MAVEN_HOME=<unzipped maven folder path>
export PATH=$PATH:$MAVEN_HOME/bin
Run the following command:
source ~/.profile
Windows
Run the following commands from the command prompt.
set MAVEN_HOME=<unzipped maven folder path>
set PATH=%PATH%;%MAVEN_HOME%\bin
For more information on installation, please follow this link.
Creating the Java project
Macintosh/Linux users, please run the following commands to create the basic folder structure of the test project.
mkdir -p soap-client/src/{main,test}/{resources,java}
Windows
After running the above commands, the folder structure should look like this:
Creating a build file
Inside the folder, we need to create build files containing the dependencies and plugin tasks. Here, we are going to use spring-boot
, spring-boot-starter-web-services
and wsdl4j
libraries for creating a SOAP client.
Gradle
Create a file build.gradle
and copy the content below into that:
plugins {
id 'org.springframework.boot' version '2.2.2.RELEASE'
id 'io.spring.dependency-management' version '1.0.8.RELEASE'
id 'java'
id 'eclipse'
id 'idea'
}
group = 'io.educative'
jar.baseName = 'soap-client'
version = '1.0.0-SNAPSHOT'
bootJar {
mainClassName = ''
}
sourceCompatibility = '1.8'
targetCompatibility = '1.8'
repositories {
mavenCentral()
}
configurations {
developmentOnly
runtimeClasspath {
extendsFrom developmentOnly
}
jaxb
}
task genJaxb {
ext.sourcesDir = "${buildDir}/generated-sources/jaxb"
ext.classesDir = "${buildDir}/classes/jaxb"
ext.schema = "src/main/resources/students.wsdl"
outputs.dir classesDir
doLast() {
project.ant {
taskdef name: "xjc", classname: "com.sun.tools.xjc.XJCTask",
classpath: configurations.jaxb.asPath
mkdir(dir: sourcesDir)
mkdir(dir: classesDir)
xjc(destdir: sourcesDir, schema: schema) {
arg(value: "-wsdl")
produces(dir: sourcesDir, includes: "**/*.java")
}
javac(destdir: classesDir, source: 1.8, target: 1.8, debug: true,
debugLevel: "lines,vars,source", includeantruntime: false,
classpath: configurations.jaxb.asPath) {
src(path: sourcesDir)
include(name: "**/*.java")
include(name: "*.java")
}
copy(todir: classesDir) {
fileset(dir: sourcesDir, erroronmissingdir: false) {
exclude(name: "**/*.java")
}
}
}
}
}
dependencies {
implementation 'org.springframework.boot:spring-boot-starter-web-services'
implementation 'wsdl4j:wsdl4j:1.6.1'
jaxb("org.glassfish.jaxb:jaxb-xjc:2.2.11")
compile(files(genJaxb.classesDir).builtBy(genJaxb))
compile 'org.testng:testng:7.1.0'
compile 'org.apache.commons:commons-lang3:3.9'
}
Maven
Create a file called pom.xml and copy the content below into that:
<?xml version="1.0" encoding="UTF-8"?>
