The problem is that you use interface-based proxying (jdk proxies) and can't access javax.swing.TransferHandler.HasGetTransferHandler interface since it has package-private visibility.

You can try cglib proxies instead.

[fabioebner]

yes but what i need to change? because i only create and call my JFrame

JFrame frame = (MyJFrame) ac.getBean("myJFrame");
frame.setVisible(true)

tks

[denis.zhdanov]

Did you setup AOP at your context?

[fabioebner]

this?

	<context:annotation-config/>
    <context:component-scan base-package="br"/>
	<aop:aspectj-autoproxy/>

[denis.zhdanov]

Use '<aop:aspectj-autoproxy proxy-target-class="true">'.

[fabioebner]

it's worked, thanks, now did you know if can i use AOP into my JFrame not managed from Spring??

tks
