Servlet Send Double Quotes to Webpage as Ajax

I have a servlet that I want to send javascript via ajax call:

private String returnImage(String img, String imgFailOver) {
String str="<img src='http://Foo.com/images/"+img+".jpg' onError='this.onerror = null; this.src=\""+imgFailOver+".jpg\";' height='500' width='500'/><br/>";
return str;
}

Basically trying to have servlet send this:

<img src="image.png" onError="this.onerror=null;this.src='/images/noimage.gif';" />

From this SO doc.

My question/ problem is why do the escaped double quotes in servlet not register (get ignored) on the webpage? enter image description here

PS- I'm tagging Java and Javascript b/c I'm not sure what side to fix this on?

You need to put &quot; instead of \". The HTML parser in the browser is unable to read \", this is a Java double quote escape.
