I frame not displaying blob (document) from action class

[Aditya Raghu]

Hi all,


I have an iframe in a jsp class which is calling a struts2 action class in its src, but instead of opening inside the frame the file is getting downloaded,

Inside file TempContentPage.jsp:

<s:form>
<iframe id="displayFrame" src="ContentPage.action"  width="1000" height="500" FRAMEBORDER="0" value="1"> </iframe>
</s:form>

Here is the execute method in the action class ContentPage.java

public String execute() throws IOException {

        Session session = SessionUtil.getSession();
        session.beginTransaction();
        ServletOutputStream out = res.getOutputStream();
        ContentBase cb = new ContentBase();


        String quer = "from ContentBase cb where cb.parentType=? AND cb.parentId=? ";
    Query query = session.createQuery(quer);

    query.setParameter(0, "FILE");
    query.setParameter(1, "1");

    list = (ArrayList) query.list();

     if (null != list && !((java.util.ArrayList) list).isEmpty()) {
                 cb = (ContentBase) ((java.util.ArrayList) list).get(0);
     }

     docContent = cb.getFile();
     res.reset();
     res.setContentType("application/msword");
     res.setHeader("Content-disposition", "inline; filename=\"scovr.doc\"");


     try{
     InputStream in = docContent.getBinaryStream();

     //InputStream iStream =  new ByteArrayInputStream (docContent.getBytes(0, (int) docContent.length()));

     int length = (int) docContent.length();
     int bufferSize = 1024;
     byte[] buffer = new byte[bufferSize];
        while ((length = in.read(buffer)) != -1) {
                out.write(buffer, 0, length);

        }

        player.setIsRead(true);

        in.close();

     }catch(Exception e){

         e.printStackTrace();
     }

        out.flush();
        return SUCCESS;
}

And here is the struts.xml mapping

<action name="ContentPage" class="com.zoran.action.ContentPage">
                 <result name="success" type="stream">
           <param name="contentType">application/msword</param>
           <param name="inputName">in</param>
           <param name="bufferSize">1024</param>
           <param name="contentDisposition">inline</param>
          </result>

                <result name="error" >/pages/ContentPage.jsp</result>
                <result name="input" >/pages/ContentPage.jsp</result>
</action>

I want to open the file inside the iframe scope, Please help me out .

Thanks, Aditya

I don't remember whether Firefox is able to embed MS Word inside an iframe, maybe this is possible only in IE.

I tried in ie too, even there the file is being downloaded. Do you see any other way of passing the stream to iframe? Is there any other alternative to this?


Thanks,

I think that you're not using Struts' stream result correctly, instead of providing an InputStream and have the framework stream it to the client you're writing it directly to the servlet's output stream (is res the ServletResponse?). Take a look at the docs and fix it. Nevertheless, I don't think that this will solve your problem...

Thanks a lot Lorand. Will look at it
