Logic inside tRowJava

Hi, I'm fairly new to Talend (we're a licensed customer, Talend Big Data) so thanks in advance.

So in tRowJava, I want get the domain name from a string called url. So I have a input_row.url and an output_row.url

I found the below function but I can't seem to refer to it when I put in inside the body of the code. I've also tried pulling pieces out of the function (URI uri = new URI(url) and put in body of code but that doesn't seem to work either. Any suggestion on how I can achieve this? Thank you!

public String getHostName(String url) {
URI uri = new URI(url);
String hostname = uri.getHost();
// to provide faultproof result, check if not null then return only hostname, without www.
if (hostname != null) {
return hostname.startsWith("www.") ? hostname.substring(4) : hostname;

}
return hostname;
}

Hi,

You'll need to either refactor that code as a static class and call it as a static routine, or bring into into the tJavaRow, but as Java statements rather than a public class - something like:

URI uri = new URI(input_row.url);

String hostname = uri.getHost();

if (hostname != null) {
output_row.hostname = hostname.startsWith("www.") ? hostname.substring(4) : hostname;

}
output_row.hostname = hostname;
}

Thank you, I removed the code from class in just put inline inside main body. To keep simple, I hardcoded URL and just started with the first line (

URI uri = new URI("https://jimbo.com");

) and it returns "URI cannot be resolved to a type"

You need to import the java.net package to do this or use the following code...

java.net.URI uri = new java.net.URI("https://jimbo.com");
