RE: [displaytag-user] how to change default extension from '.jsp' to '.csv' for CSV Export?

[Ajay Koranne]

Yes! The change to source code will be in TableTag.java.

The code snippet below for TableTag changes looks okay.

Call to jsp is not. It should be...

<display:setProperty name="export.csv.filename" value="thefilename.csv" />

Set the value to the name of the file you want.

 

Also, it will be a good idea to initialize that property (export.csv.filename) in the loadDefaultProperties() method. Otherwise, you might end up getting a null pointer exception at runtime, which will be really hard to track.

Thanks Ajay.

 

When you say that have to modify the source code, it means modify at only file TableTag.java?

 

In doEndTag() of TableTag.java, if I add lines like below, in existing try-catch

 

try
            {
          //      out.clearBuffer();
          //      out.clear();
                if(exportType == 1)
                {
                    res.setContentType(prop.getProperty("export.csv.mimetype"));
                    fileName = prop.getProperty("export.csv.filename");                            // new code
                    res.setHeader("Content-Disposition", "attachment;filename=" + fileName);  // new code
                    out.write(buf.toString());
                    out.flush();
                } else
                if(exportType == 2)
                {
                    res.setContentType(prop.getProperty("export.excel.mimetype"));
                    out.write(buf.toString());
                    out.flush();
                } else
                if(exportType == 3)
                {
                    res.setContentType(prop.getProperty("export.xml.mimetype"));
                    out.write(buf.toString());
                    out.flush();
                }
                returnValue = 5;
            }

 

and in JSP

<display:setProperty name="export.csv.filename" value="false" />

It should work?

Anywhere else, modification required?

Pl confirm this ASAP.

Thanks a lot in advance.

For 0.8.6 tag library, you will have to change the source code.

I added new properties "export.csv.filename", "export.excel.filename".

Modify doEndTag() to add...

fileName = prop.getProperty("export.csv.filename");

res.setHeader("Content-Disposition", "attachment;filename=" + fileName);

Make sure to initialize the property values in your jsp call.

Hi,

I am using version 0.8.6 of display-tag library. Right now when I click on link 'CSV' and try to save it, its taking the default saving file name as myreport.jsp (whatever the JSP file name where the display-tag is being used).

How can I change this default file name that is coming upon saving the file to the new extension .csv?

Pl help me, this is very urgent.

Thanks
Jasmin
