How does Java work in Talend?

Anonymous — Thu, 16 Mar 2017 14:57:43 GMT

I am trying to learn Java within Talend and seems to be running into errors. The code works fine here:
http://ideone.com/ydUNgo

import java.util*;
import java.lang.*;
import java.io.*;
class Stringdemo 
{
	public static void main (String [] args)  throws java.lang.Exception
	{
		String str1 = "Jake Wagner";
		String str2 = "Tony Ruggeri";
		String str3 = "tony ruGGeri";
		
		// checking for equality
		boolean retval1 = str2.equals(str1);
		boolean retval2 = str2.equalsIgnoreCase(str3);
		
		// prints the return value
		System.out.println("str2 is equal to str1 = " + retval1);
		System.out.println("str2 is equal to str3 = " + retval2);
		
	}
}

Error in Talend using tJava:
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
Syntax error on token "import", assert expected
java.util cannot be resolved to a type
Syntax error on tokens, delete these tokens
java.lang.java cannot be resolved to a type
Syntax error on tokens, delete these tokens
Syntax error on token "*", class expected
The method main cannot be declared static; static methods can only be declared in a static or top level type
Any assistance would be appreciated.
Thanks in Advance,
CM

Hi,
Move import to Advanced setting tab dedicated section.
If you need to declare classes and methods, use routine. In tJava* components, just use plain Java.

Can you be a bit more specific on what you are trying to achieve? Simply importing your predefined classes can happen by going to "Advanced Settings" tab of the tJava component and adding them. If its a non-standard library, you may want to use tLibraryLoad component in pre-job or main job and then register the imports in the "Advanced Settings" tab.
