Embed Silverlight on Spring web application

I was trying to embed a Silverlight application in HTML using Spring and I have problems because the application doesn't show up, but when I use the same code in a simple html (just a folder with Silverlight file + the HTML file) Silverlight works fine, so I want to know if somebody can help me with this.

<object width="100%" height="100%"
        type="application/x-silverlight-2" 
        data="data:application/x-silverlight-2," >
    <param name="source" value="/resources/Silverlight/private/SilverlightApplication2.xap"/>
    <param name="onerror" value="onSilverlightError" />
    <param name="background" value="white" />
    <param name="minRuntimeVersion" value="4.0.60310.0" />
    <param name="autoUpgrade" value="true" />
    <param name="enableHtmlAccess" value="true" />
    <a href="http://ift.tt/1DYtpl2" 
            style="text-decoration: none;">
        <img 
                src="http://ift.tt/13MoAIc" 
                alt="Get Microsoft Silverlight" 
                style="border-style: none"/>
    </a>
</object>
