[resolved] Undefined function and use tLibraryLoad

[param75]

Hello,
I need to use the library "commons-lang3" and more specically the function "unescapeHtml4".
So I use a tLibraryLoad and a tjava. In the tjava I just have "System.out.println(unescapeHtml4("<Français>"));"
But I have the message error : "La méthode unescapeHtml4(String) est indéfinie pour le type test_library"

So I've tried with another method : I use the "User Libraries Preferences". I add the .jar in this window
I use just a tjava with :
String test = "<Français>";
System.out.println(org.apache.commons.lang3.StringEscapeUtils.unescapeHtml3(test));
But I have the message error :

How can I use an external library ?

(I've take the library "commons-lang3-3.1-bin.zip" on this website http://commons.apache.org/lang/download_lang.cgi)
Thank you,
Carole

Hi
You should import the class before using it, go to the advanced setting tab of tJava:

import org.apache.commons.lang3.StringEscapeUtils.unescapeHtml4;

or use the class with full package path:

System.out.println(org.apache.commons.lang3.StringEscapeUtils.unescapeHtml4("<Français>"));
