ora:returnstatic() sounds like an Oracle specific XPath function. We don't support such functions. Thanks, Antoine

Hi,

Thank you Antoine for reply,

but its the name only, but it should match, like valx,

if i am doing wrong just explain me
what is difference between valx and ora... or some other key words are there????

and this my xpath coding

Code: :


 

<div1 id="Custom function" xmlns:ora="java:com.example.xpath.GetStatic">
<head>custom functions Return static</head>
<div2 id="func-return-static">
        <head>ora:returnstatic</head>
    <example role="signature">
        <proto name="returnstatic" return-type="xs:int" returnEmptyOk="no" returnSeq="no"
                returnVaries="no" isSchema="yes" isDatatype="no" isSpecial="no" isOp="no">
            <arg name="arg1" type="xs:any" emptyOk="no"/>           
        </proto>
    </example>
    <p>This function generates status for particular day</p>
</div2>
</div1>

I don't understand what you mean by valx. If I understand correctly, you defined a custom XPath operation. Did you define this operation on the server as well, by dragging its jar to the appropriate folder ? Thanks, Antoine

No, the ora prefix is not reserved, you should be fine using it.

OK, I found the problem. The function you defined needs a non-null argument:

Code: :


 
<arg name="arg1" type="xs:any" emptyOk="no"/>

but when using it, you used it without arguments:
concat("Test", ora:returnstatic())

Please make sure you give an argument to the function or define it with an optional argument so that the XPath engine can find it.

Thanks,

Antoine
