Cannot find file source when processing file with execAndWait interceptor of struts-jquery

Question

Using struts-jquery, I've created a page that allow an user to upload an excel file, and have the contents displayed without refreshing the page.

When I try to use execAndWait interceptor to display a wait page as a remote page, I receive an exception telling me it can't find source of the file.

Can someone provide an answer?

Update I got null pointer exception for the uploaded file object

java.lang.NullPointerException at java.io.FileInputStream.(Unknown Source)

when I tried to pass a file object (from the jsp page) as an argument on the following line

Workbook.getWorkbook(file);

This is my action in the struts.xml

<action name="readExcel" class="th.co.gosoft.gosd.action.ImportDataAction" method="readExcel">
        <interceptor-ref name="execAndWait">
            <param name="delaySleepInterval">500</param>
        </interceptor-ref>
        <result name="wait">/jsp/goSD/wait.jsp</result>
        <result name="success">/jsp/goSD/SearchTable/importPreview.jsp</result>
    </action>

But when I remove the

interceptor-ref name="execAndWait"

Everything is fine.

A post of the exact error message would definitely help. – mmalmeida Jan 03 '13 at 18:08 — mmalmeida, Jan 03 '13 at 18:08

It is because you are using ONLY execAndWait interceptor for your action. You need to define defaultStack also.

<action name="readExcel" class="th.co.gosoft.gosd.action.ImportDataAction" method="readExcel">
        <interceptor-ref name="defaultStack" />
        <interceptor-ref name="execAndWait">
            <param name="delaySleepInterval">500</param>
        </interceptor-ref>
        <result name="wait">/jsp/goSD/wait.jsp</result>
        <result name="success">/jsp/goSD/SearchTable/importPreview.jsp</result>
</action>
