Issue JavaBeans with Forms

Question

Hello Everyone,
I would like to know if someone can tell me what i'm wrong.
I have tryed JavaBean AWTFileDialog to see how it's works inside a Forms.
When i click button, the FileDialog open, everything looks good.
I try to create a JavaBean with Eclipse.
My Code
package oracle.forms.fd;
import java.awt.Component;
public clas myJB extends Component {
      public string getTextSample() {
           String sText = "";
           sText = "foobar";
           return sText;
I export to jar file in my oracle form directory.
edited my formweb.cfg file to add myJB jar file like i've done with AWTFileDialog.
but when i try in my form, the return value are null
my form code.
When-new-form-instance trigger
FBean.Register_Bean('CTRL.BEAN', 1, 'oracle.forms.fd.ADLog');
and i have a button to get the value like this
cV_co_retr := FBean.Invoke_Char('CTRL.BEAN', 1, 'getTextSample');
what i've done wrong?
I miss something?
thanks for help.

Hi, thanks again for your help.
I use JRocket 1.6.14 R27.6.5 32 bit, my Forms Developer version is 11.1.1.2.0
i would like to sign my jar file, but i really start with this kind of dev.
i've take a look at this link
http://docs.oracle.com/javase/tutorial/deployment/jar/signing.html
when i try the
jarsigner jar-file alias 
i get this error about unable to load .keystore file (unable to find specified file)
how i can create keystore file? with something like this ? https://www.sslshopper.com/article-most-common-java-keytool-keystore-commands.html
keytool -genkey -alias mydomain -keyalg RSA -keystore keystore.jks -keysize 2048
Does that mean i need to resign my jar on each domain?
Thanks ..
EDIT : I think i miss something, i have created my keystore file and compiler my jar with jar -cvf myjava.jar myjava.java
Does it's possible it's because i don't have JInitiator? if i try with any other jar from this site http://forms.pjc.bean.over-blog.com/ all works good, if i try with my jar file, nothing woks.
i have compiled created java from pjc.beans.over-blog and the jar stop working.
so i'm really lost, what i'm doing wrong to create my jar file.
i have tryed the 3 files given by FrancoisDegrelle to create keystroke at this link https://forums.oracle.com/thread/2154907 and it sound good, but my jar not working again.
thanks
