Man, this is really sick ;-). If I'm understanding you, maybe this will work (or
maybe not...):
var products = new Array();
<logic:iterate id="productBeans" name="products" indexId="i">
var productBeans<bean:write name="i"/> = new Array();
<logic:iterate id="productBean" name="productBeans" indexId="j">
productBeans<bean:write name="i"/>[<bean:write name="j"/>] = ["<bean:write
name="productBean" property="productName"/>",
"<bean:write
name="productBean" property="productId"/>"];
</logic:iterate>
products[<bean:write name="i"/>] = productBeans<bean:write name="i"/>;
</logic:iterate>
