Java code:


File filePic = new File (path + "1-ab1.png");
if (filePic.exists ()) {
    FileInputStream is = new FileInputStream (filePic);
    int i = is.available (); // get file size
    byte data [] = new byte [i];
    is.read (data); // read data
    is.close ();
    response.setContentType ("image / *"); // Set the file type returned
    OutputStream toClient = response.getOutputStream (); // Get the object that outputs binary data to the client
    toClient.write (data); // output data
    toClient.close ();
}


Path: the folder directory where the picture is located



JSP page Code:

<img id="mutationImage" style="height:150px;width:750px;" src="${pageContext.request.contextPath}/two-check/validate-order-mutation/seeChrom.action?chromId=${request.chromId}&t=<s:property value=‘verifyResultNote‘/>"/>





T=<s:property value= ' Verifyresultnote '/> represents a timestamp
