[vismay2011]

Hi,

I am new to Jboss 7.   I have Jboss 7.0.1 build with JDK - jdk1.6.0_38. (64-bit)  I have managed to migrate my  ".war" files  from Jboss 4.23.000 to Jboss 7.0.1 . But I am keep getting the below mentioned exception an my application does not seems to be working..

Can someome please give me a hint why I am getting this exception..?  I did some cross check to see if the  "rt.jar" present in the JRE bundle has  WindowsLookAndFeel   class, Yes its there ..

thanks in idvance.

I would guess that the jdk module doesn't export that. https://community.jboss.org/message/780767 talks about a workaround for exporting similar stuff.

BTW, swing classes should not be used inside a EE application.

Maybe you need to find out why this class should be used

hi we have a common code being used for a standalone swing based client and a web part..

Hi Nick  & others thanks for your time.. I got it working by adding the following fragment

<jboss-deployment-structure xmlns="urn:jboss:deployment-structure:1.1">
    <deployment>
        <dependencies>
            <system export="true">
                <paths>
                    <path name="com/sun/net/ssl/internal/ssl"/>
     </paths>
            </system>
   <system export="true">
                <paths>
                    <path name="com/sun/java/swing/plaf/windows"/>
                </paths>
            </system>
        </dependencies>
    </deployment>
</jboss-deployment-structure>

This was what fixed this error for me.  We had recently moved Wildfly running Workpoint from Windows Server 2008 to 2012, and this error cropped up.  Adding <path name="com/sun/java/swing/plaf/windows"/> to our module's dependencies is what corrected the problem.
