Hi,
I have the following defined:
<action name="generatePdf" class="com.abc.ReportAction"
method="generateReport">
<result name="success" type="stream">
<param name="contentType">application/pdf</param>
<param name="inputName">fileStream</param>
<param name="contentDisposition">filename="Report.pdf"</param>
<param name="bufferSize">1024</param>
</result>
My action lookks like this
public String generateReport() {
//use api to build PDF
//the api takes an output stream
//so at the end of my method i have an output stream containg the file...
//bout is my output stream
//file stream is a member of my Action (referenced in the <param
name="inputName">fileStream</param> param)
//fileStream is an InputStream
fileStream = new ByteArrayInputStream(bout.toByteArray());
return SUCCESS;
}
You will have to parameterize the XML to handle multiple file types:
<param name="contentType">${mimeType}</param>
Which you will set in your action. Same goes for the other parameters.
I'm not sure how to get the browser to display a save dialog, I think
it has to do with the mime type. I think application/octet-stream
will work.
