I have a pretty weird problem, here it goes:

I have a jsp page, in this jsp, there is an iframe showing some content from another jsp. I want this iframe to be refreshed in the <body onload="blabla"..>

So what I tried to do is, I converted the static HTML iframe code into a java code in a method. So it was like this:

.
.
html here …

<iframe ... blabla>
</iframe

html here..
.
.

And I did it like:

<body onload="refreshiframe();">

.
.
html here …

<%! void refreshiframe()
{
out.print("<iframe.. blabla> </iframe>");
}
%>

html here …
.
.

But the problem is, the out.print inside refreshiframe gives compile error. My compiler, jdeveloper 10g, specifically says that “variable ‘out’ not found”. I can use out.print outside of the method but not inside the method. How can I use out.print in the refreshiframe() method ? or is there a better way to solve this problem ? Thank you.

    Indeed, you’re confusing Java/JSP with JavaScript.

    The <body onload> should point to a JavaScript function, not to a Java/JSP method. If I understand you right, you want to refresh/reload the content of an iframe? If so, add the following to the <head> of your HTML document.

    <script>
    function refreshiframe() {
        document.getElementById('frameId').contentWindow.location.reload();
    }
</script>

    And give your <iframe> element an id="frameId".

    <iframe id="frameId"></iframe>
