I have pdf file in my application. I need to display the pdf in browser. I am reading the file as a fileInputStream, I need to display the pdf in browser with in my application. But i dont have the pdf path, I have the file stream.

Please give me some suggestion and examples

I have used ajax to display the pdf, I am using the call_method() javascript ajax request method to call the showPdf action, In showpdf action just converting the pdf file as ByteArrayOutputStream and write the result in the out put stream. But it showing the below metioned result.

Result in JSP:

%PDF-1.4 %�� 1 endstream endobj 4 0 obj <>>>/MediaBox[0 0 595 842]>> endobj 1 0 obj <> endobj 3 0 obj <> endobj 5 0 obj <> endobj 6 0 obj <> endobj xref 0 7 0000000000 65535 f 0000000389 00000 n 0000000015 00000 n 0000000477 00000 n 0000000232 00000 n 0000000540 00000 n 0000000585 00000 n trailer <<142354f5ebefd65d6aacd33a7cb2b4ab>]/Info 6 0 R/Size 7>> startxref 707 %%EOF

Please give some suggestion.

Javascript ajax:

call_method(); <br/>
function call_method(){

    Ext.Ajax.request({
            waitMsg: 'Saving changes...',
            url:'test.action?method=showPdf',
            params : { },       
            failure:function(response,options){

            },
            success:function(response,options){
                $("#pdf_content").show();               
                $("#pdf_content").html(response.responseText);
                $("#pdf_content").show('slow');
            }
    });
}

Java Methods:

public String showPdf() throws IOException {

    getResponse().setContentType("application/pdf");

    getResponse().setHeader("Content-disposition","inline; filename=automatic_start.pdf" );


    ByteArrayOutputStream baos = getByteArrayOutputStream();

    getResponse().setContentLength(baos.size());

    ServletOutputStream sos;

    sos = getResponse().getOutputStream();

    baos.writeTo(sos);

    sos.flush();

    return null;
}


private ByteArrayOutputStream getByteArrayOutputStream() throws IOException {

    String filePath = "/homefolder/";

    String folderPath=filePath+"1122/automatic_start.pdf";

    File file = new File(folderPath);

    FileInputStream fis = new FileInputStream(file);



    ByteArrayOutputStream bos = new ByteArrayOutputStream();
    byte[] buf = new byte[256];
     try {
            for (int readNum; (readNum = fis.read(buf)) != -1;) {
                bos.write(buf, 0, readNum); //no doubt here is 0
                //Writes len bytes from the specified byte array starting at offset off to this byte array output stream.
                System.out.println("read " + readNum + " bytes,");
            }

        } catch (IOException ex) {
            ex.printStackTrace();
        }


    return bos;
}
