Display an attachment from jsp
Hello,
I store my web application attachments under ROOT folder and my problem is that I can access to them also if I write directly the appropiate url in the browser without entering in the application...
How should I do to access to files only through a servlert which authenticate the user and not directly from url?
Thanks

Any idea?
Thanks

Display download window from JSP
Hi,
I hava a links to PDF files on a JSP. These PDF files are not in the web server virtual path. When user clicks a link in the browser then it should display download or open from current location window. How can I do this. Please help me.
Thanks,
SimiThe following code you post the complete filepath to a servlet
Recommendations:
Replace the filepath by a pointer to a session-variable or database-entry
by which you can dynamicaly retrieve and keep the full path on the serverside.
Code:
in your for jsp insert:
use <a href="#" onClick="downloadform.FILENAME.value="<%= your dynamic path here %>">download <%= your dynamic path here %></a>
<form method=post name=downloadform action="servlet/DownloadServlet">
<input type=text name=FILENAME>

hi i am trying to read an excel file from a location on the app server and display it in the browser (ie). the excel file should open up and not display the open/save dialog.
following is the code that i am using. i am not able to get it to work. getting an illegalstateexception and also i am getting all garbage diplayed in the browser. no excel. kindly help.
<%@ page import="java.io.*" contentType="application/vnd.ms-excel"%>

ServletOutputStream so = response.getOutputStream();
String filename = "C:\\example1.xls";
String mimetype = "application/vnd.ms-excel";

InputStream in = new BufferedInputStream(new FileInputStream(filename));

output.write(bytebuff, 0, lengthread);
byte data[] = output.toByteArray();
response.setContentType(mimetype);
so.write(data);
in.close();
so.close();
%>A JSP calls getWriter() by default.
Every time you have a carriage return outside <% %> it gets written to the writer.
The Illegal state exception would be because you are getting the outputStream after the writer.
This is better done in a servlet, but can be done in a JSP, try it with code like this:
<%@ page import="java.io.*" contentType="application/vnd.ms-excel"
%><%@ taglib uri="/WEB-INF/tlds/sapphire.tld" prefix="sapphire"
%><%@ taglib uri="/WEB-INF/tlds/c.tld" prefix="c"
%><%
%> Note that there is no text at all outside of the <% %> (not even carriage returns)
Also, why are you writing to a ByteArrayOutputStream (ie into a memory byte array), and then writing the byte array to the servletoutputstream?
Just put a buffer around the servlet outputstream and write directly to that.
ServletOutputStream so = response.getOutputStream();
BufferedOutputStream output = new ByteArrayOutputStream(so);

Display multiple Images from a DB on a JSP Page!
Hi all, please give me your solution, thanks. I have many images, stored in Oracle database (BLOB), How to display all of them (images) on a JSP page? I have a working solution that only shows one image based on the specific image-name passed. But if no image found in the Database with that image-name then I want to show all the images at once on a JSP page. Can someone help please. Follwing are the code snippets:
Here is the JSP page that calls the servlet to show the images:
<%@ page contentType="text/html;charset=windows-1252"%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=windows-1252">
<title>untitled</title>
</head>
<body valign=center>
<table>
<tr>
<td>
<img src="/test-testimgs-context-root/servlet/test1.images.servlet.GetImage">
</td>
</tr>
</table>
</body>
</html>
Here is the code that resides in the service method of GetImage servlet:
public void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
OutputStream stream = response.getOutputStream();
Blob imgBlob = null;
ResultSet rs = null;
byte[] imbBytesAry = null;
try
ImageTest imgtest = new ImageTest();
rs = imgtest.get("img1.tif");
if(rs != null)
while(rs.next())
imgBlob = rs.getBlob(1);
int len = new Integer( new Long( imgBlob.length()).toString() ).intValue();
imbBytesAry = imgBlob.getBytes(1,len);
if (imbBytesAry.length == 0 || imbBytesAry == null)
noImageFound(request, response);
else
stream.write(imbBytesAry);
else
noImageFound(request, response);
catch (Exception e)
noImageFound(request, response);
Here is the code that resides in the get method of ImageTest class:
public ResultSet get(String fileName) throws DatabaseConnectionException, SQLException, Exception
Connection connection=null;
ResultSet rs = null;
ResultSet rs1 = null;
Blob imgBlob = null;
try
connection = new ConnectionProvider().getCConnection() ;
connection.setAutoCommit(false);
Statement stmt = connection.createStatement();
String sql = "SELECT IMG FROM IMAGE_TABLE WHERE IMAGE_NAME = ? ";
PreparedStatement pstmt = connection.prepareStatement(sql);
pstmt.setString(1,fileName);
rs = pstmt.executeQuery();
boolean flag = rs.next();
if(flag)
rs.beforeFirst();
else
sql = "SELECT IMG FROM IMAGE_TABLE";
rs1 = stmt.executeQuery(sql);
boolean flag_all = rs1.next();
if(flag_all)
rs1.beforeFirst();
else
rs1 = null;
return rs;
}As you see in the JSP page I am calling GetImage servlet, whose service method does all the processing i.e. calls ImageTest get method that queries the database and returns the result. Eventually what I would like is to pass the filename along with other parameters from JSP page and the servlet returns the images based on that. Currently I have just hard coded a value for testing puposes. Any help is appreciated.

How do I Display a string from a servlet into a JSP Page???? NEED HELP!!!!
Hi guys,
How do I Display a string from a servlet into a JSP Page...
Ive tried so many bloody things!.....
Simply.
I get text from JSP. The servlet does what ever it does to the string.
Now. Ive create sessions and bean things,.... how the hell do I display it in a text box... I can display on the screen.. but not in the text box.!!!
please help!!!hmmm, I dont really like using JSP programming, u should be using JAVA..

Call and cast to the bean like this:
<%@ page import="beans.*" %>
<% //cast to bean get request create object
userNameBean u= (userNameBean) request.getSession().getAttribute("userNameBean");
then... all you do is call it like this:

Unable to open URL attachment from SBWP in CRM WEB UI
Hello Gurus,
Need your help please. I'm having some problem opening the URL attachment from SBWP via CRM 7 WEB UI (I used a Transaction Launcher for SBWP). The attachment is a Webdynpro application. I am able to open the attachment in SAP GUI, but not in CRM WEBUI. This problem occured when we update the SP level of CRM 7.
Here's the scenario,
- whenever I click the attachment, it open a new window, which also happen even before SP level update, with the following information:
Execute an Application on FrontEnd
Please wait. You will be forwarded automatically.
This page is included for technical reason.
Execute program.
Status: Displaying Office Document ..........
After a couple of seconds, it will return to the Workflow Workplace screen.
I have checked the workflow log and found no inconsistency on the attached URL.
Immediate response would be highly appreciated. Thanks in advance.
Regards,
EdwinThanks for the reply WD ABAP.
Yes, I did try to use the functionality of Worklist and the URL attachment successfully opened. However, there are some limitation in its functionality as indicated in the link below that opted us to use the SBWP in CRM WEB UI via transaction launcher.
http://wiki.sdn.sap.com/wiki/display/CRM/CRMWorklist-AdvancewithDialognotSupported
We don't want to adjust the logic of our existing workflow at this point as described in the above link as it will entails end-to-end testing again. We just encountered this issue when we update the SP level of CRM 7.
Hope there is an alternative solution without shifting us to Worklist.

Accessing JSTL values from JSP
I've run into a problem I'm not sure has a solution. Could be bad design on my part, or just a poor imagination. If this has been answered previously, please point me to the post.
I am using some JSTL to do a SQL query and displaying the records in a select box:
<sql:query var="aResults" sql="select * from TYPE_STATE_LIST where tslAllowable=1" />
<c:forEach var="oRecord" items="${aResults.rows}">
<option value="<c:out value="${oRecord.tslID}" />"><c:out value="${oRecord.tslFullName}" /></option>
</c:forEach>I want to be able to reset their selection to the value they entered when the form is refreshed, though. I'm trying to figure out how to grab the oRecord value from the JSTL and use it in a JSP IF statement:
<% if( oRecord.tslID==request.getParameter("state") ) { %>
<option selected value="<c:out value="${oRecord.tslID}" />"><c:out value="${oRecord.tslFullName}" /></option>
<% } else { %>
<option value="<c:out value="${oRecord.tslID}" />"><c:out value="${oRecord.tslFullName}" /></option>
<% } %>I thought about using the JSTL <c:choose> tag instead, but then how would I access the previous value with request.getParameter()?
Any suggestions?${param.state}It's better if you place the sql query into a class rather than display it in the jsp, it's more flexible and programmable.

Problem with displaying BLOB images on JSP page using a servlet
hi. I have a big problem with displaying BLOB images using JSP. I have a servlet that connects to the oracle database, gets a BLOB image , reads it, and then displays it using a BinaryStream. The problem is , this works only when i directly call that servlet, that is http://localhost:8080/ImageServlet. It doesn't work when i try to use that servlet to display my image on my JSP page (my JSP page displays only a broken-image icon ) I tried several coding approaches with my servlet (used both Blob and BLOB objects), and they work just fine as long as i display images explicitly using only the servlet.
Here's what i use : ORACLE 10g XE , Eclipse 3.1.2, Tomcat 5.5.16 , JDK 1.5
here is one of my image servlet's working versions (the essential part of it) :
BLOB blob=null;
rset=st.executeQuery("SELECT * FROM IMAGES WHERE ID=1");
while (rset.next())
blob=((OracleResultSet)rset).getBLOB(2);
response.reset();
response.setContentType("image/jpeg");
response.addHeader("Content-Disposition","filename=42.jpeg");
ServletOutputStream ostr=response.getOutputStream();
InputStream istr=blob.getBinaryStream(1L);
int size=blob.getBufferSize();
int len=-1;
byte[] buff = new byte[size];
while ((len=istr.read( buff ))!=-1 ) {
ostr.write(buff,0,len);
response.flushBuffer();
ostr.close(); and my JSP page code :
<img src="/ImageServlet" border="0" > If you could just tell me what i'm doing wrong here , or if you could show me your own solutions to that problem , i would be very greatful ,cos i'm realy stuck here , and i'm rather pressed for time too. Hope someone can help.I turns out that it wasn't that big of a problem after all. All i had to do was to take the above code and place it into another JSP page instead of into a servlet like i did before. Then i just used that page as a source for my IMG tag in my first JSP. It works perfectly well. Why this doesn't work for servlets i still don't know, but it's not a problem form me anymore . Ofcourse if someone knows the answer , go ahead and write. I would still appriceatte it.
here's the magic tag : <img src="ImageJSP.jsp" border="0" > enjoy : ) -
hello,
I am facing a design issue of so as to how to go about displaying an image which i am retrieving from database.
I have a SubmitDoc.jsp which takes as input the doc id which i need to display looks like :
*SubmitDoc.jsp*
<FORM METHOD=POST ACTION="Retrieval">
Enter Document ID to Retrieve: <INPUT TYPE=TEXT NAME=DOCID SIZE=20/><BR>
<P><INPUT TYPE=SUBMIT></P>
</FORM>I have my Retrieval servlet which access the DB and gets the binary stream for the image data based on DOCID.
Now i try to forward result to a different jsp in order to display the binary data from the servlet.
something like this :
InputStream readImg = rs.getBinaryStream("DOCUMENT");
response.setContentType("image/jpg");
request.setAttribute("ImageData", readImg);
// response.getOutputStream().write(rb,0,len);
RequestDispatcher rd = request.getRequestDispatcher("DisplayDoc.jsp");
rd.forward( request, response );What code should i put in DisplayDoc.jsp to show the image there.
Any ideas how do i go about ?
Thanks,What code should i put in DisplayDoc.jsp to show the image there.The same code you put in any html page to show an image:
<img src="urlToDownloadImageFrom"/>In effect you have two requests.
One for the JSP page, and then another for the image.
So often what you find is the tag on your page needs to pass the id as well
<img src="/ImageServlet?docId=abc123"/>
