Welcome to JavaRanch.

and problem is that i cann't open my applet in web

What does this mean? What, exactly, are you doing, and what, exactly, is happening as a result? Also, check the Java Console for any error messages.

By the way, if the applet is signed, you do not need to alter permissions - both accomplish the same thing.

When i open my html file, I get message :
and when I press Details:
CacheEntry[file:/C:/Users/Jet/workspace/Zaidimas/bin/SSSignedApplet.jar]: updateAvailable=false,lastModified=Fri Jan 31 13:50:46 EET 2014,length=6367
Missing Application-Name manifest attribute for: file:/C:/Users/Jet/workspace/Zaidimas/bin/SSSignedApplet.jar
Missing Permissions manifest attribute in main jar: file:/C:/Users/Jet/workspace/Zaidimas/bin/SSSignedApplet.jar

Maybe I need somehow run java.policy.applet in eclipse when applet started without any keys...?
but when i use html code like:

and when I open website it shows me that cannot read pictures, but I grant all permisions...
