then I'm check or test java on opera browser. below is step what I'm do for testing.
1. open opera bowser
2.type on address bar http://www.java.com/en/download/testjava.jsp
3.I get message from page in opera browser, the message is: missing plug-in
so the mean java not installed in opera browser.
4. I try check with this command:
locate libnpjp2.so
and the output is :
/usr/java/jdk1.7.0/jre/lib/amd64/libnpjp2.so
/usr/java/jdk1.7.0/lib/amd64/libnpjp2.so

find / -name libnpjp2.so 2>/dev/null
and the output is :
/usr/java/jdk1.7.0/lib/amd64/libnpjp2.so
/usr/java/jdk1.7.0/jre/lib/amd64/libnpjp2.so

so what must I do for the next step installation java on opera browser ?

and I get guide from opera website like this:
So that Java will be discovered, type the following commands:
cd /usr/lib/opera/plugins
ln -s /opt/jre-1.6.0_21/usr/java/jre1.6.0_21/lib/i386/libnpjp2.so

MIME types:
application/x-java-applet::Java(tm) Plug-in
application/x-java-bean::Java(tm)

I'm not sure the next what I must do, so I need your help.

Hello
I suspect this may be 64 bit orientated, here's what I get

]$ locate libnpjp2.so
/usr/java/jre1.6.0_21/lib/i386/libnpjp2.so

the page you linked to works fine for me, what I did notice though is in opera > preferences > plugins the java plugin uses /usr/lib/mozilla/plugins/libjavaplugin.so which is a symbolic link to /etc/alternatives/libjavaplugin.so.
Maybe you need some 32 bit libs aswell

@Bonedome, thanks for replying, I'm very appreciation your.
the problem was solved.
in my case: I use java version 1.7.0 (jdk-7-linux-x64)
so when I input command:

locate libnpjp2.so

the output is :

/usr/java/jdk1.7.0/jre/lib/amd64/libnpjp2.so
/usr/java/jdk1.7.0/lib/amd64/libnpjp2.so

and in your PC/Laptop: you may using java version 6.
output in your terminal : /usr/java/jre1.6.0_21/lib/i386/libnpjp2.so

above is version and location libnpjp2.so.
so, in my case, I think I must make a symbolic link to /usr/java/jdk1.7.0/jre/lib/amd64/libnpjp2.so or /usr/java/jdk1.7.0/lib/amd64/libnpjp2.so from location where the directory of Opera Plugins placed. and in my laptop there location is in /usr/lib64/opera/plugins.

so, the conclusion, I input this command:

cd /usr/lib64/opera/plugins
ln -s /usr/java/jdk1.7.0/jre/lib/amd64/libnpjp2.so

then I testing again on opera browser with input this address on address bar:
http://www.java.com/en/download/testjava.jsp

I got message "Your java is working"

thanks...
