Answer 1

Create one javascript like,

<script type="text/javascript">
    function newpagePDF() {
        var newpage = window.Open('/apex/ZEB_RMA_Pdf?CaseId='+{!caseid}');
    }
</script>

Change your command line code to,

 <apex:commandButton value="Generate Pdf" action="{!generatePdf}" onclick="newpagePDF()"/>

I think you have mentioned "window.open" as "windows.open" in onclick event of commandbutton.

You can see page loading (jquery or java script) errors through,right click and click "Inspect Element".Click Console and verify the list of errors there for debugging.

Answer 2

1) Create a visualforce page that takes the caseid for the controller.

2) Create an link on your page

3) place target="_blank" on your 'a' tag

the code should look like this:

    <a href='/apex/ZEB_RMA_Pdf?Id='{!caseid}' target='_blank' />

Answer 3

You can use renderAs='PDF' in your visualforce page as below

This will always open new window and display PDF page layout.
