I generate a temporary word document "docx" in the ivy files\session\ directory. Now I when the user click on a download link, the browser recognize the data as zip. How can I set the content type in the response?

The content type of the file is set automatically by Xpert.ivy by analyzing the file extension. The content type of a file extension is searched first in the cms type system. If it is not found there it is searched in the web container. And finally in a hardcoded list in Xpert.ivy.

In Xpert.ivy 5.0 the docx extension is known and the content type should be set automatically. In earlier version the docx extension is not known. You can add the following xml snipet to the webapps/ivy/WEB-INF/web.xml file so that the web container knows the extension and the content type of it:

<mime-mapping>
    <extension>docx</extension>
    <mime-type>application/vnd.openxmlformats-officedocument.wordprocessingml.document</mime-type>
</mime-mapping>

You can find out the mimeType of e File in a Java Function.

    File f; // Set your File to f 
    HttpServletRequest request;
    request = (HttpServletRequest)
                 FacesContext.getCurrentInstance().getExternalContext().getRequest();

    String type = request.getSession().getServletContext().getMimeType(fileName)

Note: File f is a java.io.File you must convert the ivyFile to a javaFile

If you want to stream the File with <p:fileDownload> you need org.primefaces.model.DefaultStreamedContent;

The Final function, which you can call in a Ivy-ScriptStep, will look something like that

public StreamedContent getStreamedConentFromFile(File file){

    StreamedContent fileDownloaded = null;
try {
       HttpServletRequest request;
       request = (HttpServletRequest) FacesContext.getCurrentInstance()
                     .getExternalContext().getRequest();
       InputStream inputStream = new FileInputStream(file);
       String fileName = file.getName();
       fileDownloaded = new DefaultStreamedContent(inputStream,
                     request.getSession().getServletContext()
                           .getMimeType(fileName), fileName);
       return fileDownloaded;
} catch (Exception e) {
       Ivy.log().debug("Fehler in setStreamedContentFromFile : " + e.getMessage());
       fileDownloaded = null;
}

file.delete();
file.deleteOnExit();

return fileDownloaded;
