Read custom created XML file from a Groovy/Java class in a J2EE Web Application

I have a following xml file that I created to store the application name and Application Owner email address

//File name: EmailInfo.xml

< emailInfo>
< application> < name> Saleways < /name> < email> david@david.com< /email> < /application>
< application> < name> Mercantile House< /name> < email> binod@hotmail.com< /email> < /application>
< application> < name> BishowShop< /name> < email> bishow@hotmail.com< /email> < /application>
< /emailInfo>


Now I have a J2EE application that contains a Groovy or a Java class that access the above XML file. The method to access above html file using Groovy is presented below. Note that the xml file resides on the same location where the class exists.


def appName=[]
def appEmail=[]
java.net.URL url= this.getClass().getClassLoader().getResource("EmailInfo.xml");
java.net.URI uri = new URI(url.toString())
File f=new File(uri)
def emailInfo = new XmlSlurper().parse(f) //Specific to groovy
emailInfo.application.name.each {appName += it} //specific to groovy
emailInfo.application.email.each {appEmail += it} // specific to groovy

You simply can modify the above code for java classes. The final result for the above code is that appName contains the list of the Name and appEmail contains the list of the Email address. You can put it into hash map as below.

def emailMap=[:] //define an empty map
for(i in 0 .. appName.size()-1)
emailMap.put(appName[i].toString(),appEmail[i].toString())

Now you simply can access the email address of a person as shown below

println emailMap[“Mercantile House”] //prints binod@hotmail.com
