Java statement in Genexus

Question

I would like to use the following Java statement in GeneXus, but I don't know GeneXus' syntax for embedded Java code.

str = new String(str.getBytes("8859_1"), "UTF-8");

How can I do it?

FYI: if you think you need to do this, you probably have done something wrong before reaching this point and may already have data-loss (depending on how exactly you reached this point). — Joachim Sauer, Oct 20 '15 at 14:41

&str = 'my text'

JAVA [!&str!] = new String([!&str!].getBytes("8859_1"), "UTF8");

Hi, Gallotti..., I used and tested your java statement in my program of Genexus. But it has java.io.UnsupportedEncodingException error. What should I do? Please could you give me any advices?Thank you so much for your help. – Nyi Ma Lay Win Lae Aye Jul 29 '15 at 06:18
UTF8 goes without "-" – Gonzalo Gallotti Jul 29 '15 at 20:04
Now , I understand why java.io.UnsupportedEncodingException error is appeared. It needs exception control. Thank you, Gonzalo. – Nyi Ma Lay Win Lae Aye Aug 27 '15 at 00:55

It needs Exception control as following.Without exception,java.io.UnsupportedEncodingException error will be appeared.

&str = 'text'

JAVA try { [!&str !] = new String([!&str !].getBytes("UTF-8")); } catch (java.io.UnsupportedEncodingException e) { }

Para incluir codigo java, necesitas usar la palabra reservada "java" al principio de cada linea. Si en esa linea necesitas acceder a una variable/atributo de GeneXus, o que esa variable sea accesible por GeneXus, necesitas rodear el nombre de la variable con [!...!] Asi que tu codigo quedaria:

java try {
java [!&str!] = new String([!&str!].getBytes("8859_1"), "UTF-8");
java } catch (Exception ex) {
...
java }
