Parameter passing into servlet

Hi,
I am trying to get the html page to pass some parameters into a servlet. Everytime I try running it, I get "Page could not be found error"
I use the following path:
Http://localhost:8080/example/servlets
I could run the HelloWorld example with no problems.
I'm trying to run the LoanAmorization.html
which calls LoanCalculator servlet.
I just modified the examples that came with jsdk2.1 to get the servlets working.
HTML code:
<HTML>
<HEAD>
<TITLE>Loan Calculator</TITLE>
</HEAD>
<BODY>
<CENTER>
<H1>Please enter the following information:</H1>
<HR>
<FORM ACTION="http://10.1.11.84:8080/examples/servlet/LoanCalculator" METHOD="GET">

Hi!
You have to insert an entry for every Servlet you use in the
web.xml file of your Servlet-Engine (e.g. tomcat):
<servlet>
<servlet-name>
LoanCalculator
</servlet-name>
<servlet-class>
pkg.LoanCalculator
</servlet-class>
<load-on-startup>
1
</load-on-startup>
</servlet>

request.setAttribute("string",parameter);
and in jsp..
request.getParameter("string");

Hi Jaykumar
You should use
<%= request.getAttribute("sting") %> or
${string}
in your jsp. I think you are trying to retrive the parameter instead of attribute.
Thanks

How to hide the parameters passed into servlet or make it read only

Hi,
I am calling a servlet to downlaod files, using
<a href="../servlet/DownloadFile?directory=<%=attachmentPath%>&fileName=<%=fileName%>">But this will display all the paramters passed , of course as I am using hyper link. However I can not use
<form> to call the servlet because otherwise I got nested form anyway.
So the users would be able to change the directory and file names to download files I do not like them to download. Somebody would suggest hardcode the directory and filename, but these two parameters are dynamic, so I have to pass them into the servlet everytime I call it.
Any advice to disable the users to change or even view the two parameters on the address bar?
Thanks
</a>

Here some code snippets to give you an idea of what I do.
Let's say you want to retrieve a file from your server, and you need to pass the full directory path info in your URL. You might have code as follows:
String fileName = "/server/SomeUltraSecretHiddenDirectory/ImportantSecretFile.doc";
Click <a href="/fileservlet?fileName=<%=URLEncoder.encode(fileName)%>">HERE</a> to download file.Using the above code, ANYONE can retrieve this file if they know the URL. Also, they could try to change the URL paths to find other files. In other words, it's NOT SECURE.
Now, try it this way (all exception handling is left out):
private static final byte[] salt = { (byte)0xd4, (byte)0xa3, (byte)0xff, (byte)0x9e,
(byte)0x12, (byte)0xc7, (byte)0xd0, (byte)0x84 };
String fileName = "/server/SomeUltraSecretHiddenDirectory/ImportantSecretFile.doc";
base64Encoder = new BASE64Encoder();
base64Decoder = new BASE64Decoder();
// get key object
SecretKey key = null;
PBEKeySpec keySpec = new PBEKeySpec("somesecretkeystring");
SecretKeyFactory kf = SecretKeyFactory.getInstance("PBEWithMD5AndDES");
key = kf.generateSecret(keySpec);
// get parameter spec
PBEParameterSpec paramSpec = new PBEParameterSpec(salt, 1000);
// create cipher
Cipher c = Cipher.getInstance("PBEWithMD5AndDES");
c.init(Cipher.ENCRYPT_MODE, key, paramSpec);
// take string and get encrypt it (base-64 encode it to get rid of non-printable characters
byte[] aResult = c.doFinal(fileName.getBytes("UTF-8"));
String strResult = base64Encoder.encodeBuffer(aResult);
// print the link
Click <a href="/fileservlet?fileName=<%=URLEncoder.encode(strResult)%>">HERE</a> to download file.
// on the server side, do the following to decrypt the link
String encryptedFileName = request.getParameter("fileName");
// create decryption cipher (i'm skipping a lot of the init code this time - see above for code example)
Cipher c = Cipher.getInstance("PBEWithMD5AndDES");
c.init(Cipher.DECRYPT_MODE, key, paramSpec);
// decrypt string
byte[] aResult = c.doFinal(base64Decoder.decodeBuffer(encryptedFileName));
String strResult = new String(aResult, "UTF-8");Now you have the decrypted String. Your link will be unreadable and unbreakable. 100% safe as long as your key password is safe. I hope that gives you an idea of what you can do with cryptography!
A few notes:
- Most of the above code is in separate methods that can be easily reused (especially encrypt() and decrypt())
- All exception handling has been left out
- The above code was patched together from memory, so don't expect it to work as is (that's my disclaimer :)
- You'll need the JCE libraries to use this functionality.
- For REALLY sensitive data (such as passwords), make sure you use one-way encryption (hashes) if you don't ever need to decrypt it again.

Parameter passing into column

Hi ,
We have one prompt as TimeHorizion. How can we pass this value in column formula.
I mean based on user selection I should pass TimeHorizion value in to column formula
I wrote following query in column formula but it is not working properly
CASE WHEN Time Horizon Duration = @{TimeHorizion}THEN "Pipeline Product Agg"."Estimated Revenue" ELSE 0 END.
If user select 30 days then we should get revenue for 30days period only
FYI: TimeHorizion values are 30 days, 60 days, 90 days and 100 days.
Due to ETL issues we can’t use that prompt value in filtters.
Any help would be appreciated.

Are you getting an error or is it simply not evaluating correctly ?
Just been playing around on my local machine, i got the following to match a Pres. Variable :
CASE WHEN <measure> = @{PV} THEN 'blah' END
but flip it over the other way (as you have) and I dont get a match :
CASE WHEN @{PV} = <measure> then 'blah' END
Try flipping the values around the operator?
Also check your datatypes match (column the prompt is based on) vs column your evalulating against

How can I get a parameter back into a servlet invoked from an IMG tag ?

I'm using a servlet to create several graphical plots per JSP i.e. per HTML page. Each graph is supposed to be different, according to a parameter which I want to pass back from my JSP. I'm getting several plots but they're all the same!
I've tried setting an attribute in the session object before each IMG SRC= , but all I get is each plot the same! In fact, my debugging efforts show that the servlet is only called once despite 3 calls, each with a different session parameter value. I'm not sure the session parameter values are getting used properly.
I just can't find a way of getting a parameter back into my servlet which is invoked from the IMG tag (i.e. SRC= "servlet name").
Can anyone tell me the best way to pass a parameter back into a servlet which is invoked from an IMG tag? Can the request object be used? I can't, at the moment, see how it could be used?
I'll certainly be very grateful if anyone can help with this - could even be useful for others as well!

You said that, "by moving a copy of Mobile Docs back to the Library, from which I had moved it, my documents reapperared in Cloud." That says that you actually moved it. Obviously, I can't tell exactly what you did, but it sounds like you may have thought you were just putting it in the sidebar, but you actually put it somewhere else. The sidebar is not a location to put things, just a way to create a quick shortcut to access a file or folder, so you can't put things "back" from there.

Null values passed into the servlet

Hi all,
I keep getting null values for all the params that I pass into the servlet i.e. sqltype, producttype, process, instance etc....I have attempted to print some of them out on the screen but I keep getting the 'NullPointerException' error message...can anyone tell me what it is that I have down wrong in the below code?
If I run the servlet with method calls that have hardcoded arguments in them it works but not when I pass in the params from the URL...I am absolutley puzzled!

}

That section of the code references a cache to extract an item that has been requested by the user. If the item is not in the cache i.e. if(o1 == null) then it will call a class that generates that object and places that object into the cache. The second time the user makes the same call then they will be handed a cached copy of that object which is aimed to make the whole servlet call faster.
That section of the code works fine coz I have tested that separately. It is the reading in of the arguments that is causing the problem.

Changing the value of a parameter that has been passed into an SSRS 2008 R2 report

I support 200+ reports that all use stored procedures and have many drill downs with built in URLs.
I want to do the below to avoid creating a brand new parameter that I will have to add to literally hundreds of places.
We have what I'll call Param1 that receives a value from the user. That Param1 is passed to the stored procedure(s) for the report and also embedded in any Action URLs for drill downs to other reports from that report. All works great.
Now I have a need to concatenate a string to whatever value they supplied which provides context for the environment in which they are running. The reason I want to do this instead of creating a new parameter is because I need this in all my reports
and as stated above I would have to make 100s of changes to make that happen. If I can figure out a way to concatenate a value to the existing Param1 value I can greatly reduce the number of changes.
I can't seem to be able to find a way to modify the value on an existing parameter that is passed into the report prior to report execution.
I get an error when I simply try to concatenate something to the parameter in its Default property.
I can't find a way to update a parameter value in the Report Code block. There don't appear to be any methods available on the Parameter Collection to set the value of a parameter.
Any ideas?
Thanks!
Nathan

Create a new parameter. Mark it internal, set it's value by expression to:
=User!UserId+"MyNewValue"
and pass it to the proc?

Issue with parameter passing in ie7 to php xml

Hi
I wondered if anyone could offer a little advice what the issue is here.
I have a page with xml generated from php in a separte file and presented by a dataset in spry.
The xml is OK and in firefox it all works but ie seems to barf on it.
The situation is this:
I have a jump menu on a front page that provides a url with anumeric parameter passed like this
platforms.php?platform_id=1
This parameter is picked up by php on the platforms.php page using the $_GET Array and is passed into the code in my Spry dataset to the file that runs my query and returns my xml- so basically the page displays a dataset filtered on this parameter id.
It works perfectly in FF.
In IE if I link straight to the page without a parameter at all- so platforms.php the page loads OK using the default parameter I have set up in the top of this page to send the default id of 1 to the code page so the spry query says platform_sql.php?platform_id=1 and the xml generator is fine with thisiel. ie I do a
if(isset($_GET['platform_id'])){
$platform=$_GET['platform_id'];
}else{
$platform=1;
The dataset loads Ok in IE but when I pass a parameter in the url from my jump menu IE gives a blank SPRY table i- it momentarily appears with just the placeholders for my dataset elements then vanishes. The source code of the page shows the correct id was set in the spry data going to my query file.
There is an error in ie saying there is a javascript error but its not any help- in ie fashion- FF shown no such errors.
I thought this might be a data type thing again in the dataset but its not - I have set the elements returned to simple strings but it still does not work.
Is there a problem passing in a parameter like this to a spry dataset?

After about half a day of mucking round I found the problem and a solution to this problem.
What appeared to have happened was that some of the older content in my database used html originally encoded using a WYSWYG editor called ktml.
Later data uses Tiny MCE. It looks like the character set of the two formats is slightly different and as a result some characters rendered incorrectly when passed through XML parsing where it specifies the character set as utf-8.
Firefox on the whole seems to ignore the issue though looking at the raw xml output of my php-xml code- where "-" characters were (dashes) there was a question mark character shown. None the less in actual use on my page the xml was produced and the dataset worked out.
In IE, it barfed at these same characters and failed to return the xml dataset.
What confused the issue more was some of my smaller datasets if they by chance never had a "-" character in rendered OK in IE- hence my default dataset (platform_id=1) worked in IE. After much experimenting I noticed other ids worked too if there was never such a character.
How I got round it was to wrap my server side data in the utf8_encode() function, and now all my xml is clean.
The javascript error being thrown was a red herring though I could not tell until I managed to run my page in ie7 with Visual Studio Express error console running- I had this on a spare machine at work so could debug with it.
All sorted now- now just need to find away to wrap all my datasets in collapsible panels that work.

Getting error Invalid length parameter passed

Hi,
I'm getting an error running my query. It say "Invalid length parameter passed to the LEFT or SUBSTRING function. I will be getting the string in between of hyphen using the code below. May i ask your assistance or idea on how to fix this issue.
thank you.
Substring(ins.itemid,11,CHARINDEX('-',ins.itemid+'-',11)-11) AS MODEL
Msg 537, Level 16,
State 3, Line 1
Invalid length parameter passed to the LEFT or SUBSTRING
function.
Sample data of Itemid.
B300-4410-ONEMAX-U
B300-1725-XWHT-U
B300-3110-VT981-U
B300-1720-DRZRKCROBLK-U
B300-1720-DRDTHN32BLK-U

That'll cause empty strings to show up into you're result set but shouldn't cause the the SUBSTRING function to fail.
The error is the result of the SUBSTRING function trying to bring back a negative number of characters.
Try running the following and see what comes back...
SELECT ins.itemid
FROM dbo.TableName ins
WHERE LEN(ins.itemid) < 11
If you don't find any itemids what are less than 11 characters (I'm 99% sure you will), try using a little test script like the following to test suspect values...
IF OBJECT_ID('tempdb..#temp') IS NOT NULL
DROP TABLE #temp
GO
CREATE TABLE #temp (
itemid VARCHAR(30)
INSERT #temp (itemid) VALUES
('B300-4410-ONEMAX-U'),
('B300-1725- '),
('B300- 3110-VT981-U'),
('B300-1720-DRZRKCROBLK-U'),
('B300- 1720-DRDTHN32BLK-U')
SELECT ins.itemid
FROM #temp ins
WHERE LEN(ins.itemid) < 11
SELECT
SUBSTRING(
ins.itemid, 11, CHARINDEX('-',ins.itemid+'-',11)-11) AS MODEL FROM #temp ins

NEED PARAMETER PASSING SAMPLE INSTALLATION ZIP FILE...

Hello All,
I was viewing the following page:
http://portalstudio.oracle.com/pls/ops/docs/FOLDER/COMMUNITY/PDK/
articles/guidelines.parameter.passing.html
Near the end of the page it reads, "For a detailed PL/SQL portlet
sample, see the Parameter Passing sample included in the PL/SQL
section including the Parameter Passing Sample Installation
article and check out the source code in the downloadable zip
file."
The phrase "downloadable zip" near the end of this line is a link
that is supposed to provide you with the zip file. When I click
on this link I get the file to save as sample.zip. Files get
downloaded but when I try to unzip it,
I encounter error messages :
Missing 1 bytes in Zip file (attempting to process anyway).
Cannot open file: it does not appear to be a valid archive.
If you downloaded this file, try downloading the file again.

let say i have a code as below:
public void init()
      String rootDirectory = JOptionPane.showInputDialog( this,
         "Please enter a directory name:" );
      FileTreePanel panel = new FileTreePanel( rootDirectory );
      getContentPane().add( panel );
   }and i use this code to call the batch file:
import java.io.IOException;
public class callbatch{
     public static void main(String args[]) {
          try {
               Runtime runtime=Runtime.getRuntime();

               catch(IOException ioe) {
                    System.out.println(ioe);
     }how can i pass the rootDirectory into my callnvcc.bat?

Adding a CM: Invalid length parameter passed to the RIGHT function. (CINF)

We started seeing this error message a week ago when attempting to add a Credit Memo. We only see this error message when entering Credit Memos and not any other finacial documents. I've done some preliminary research and haven't really come up with anything to point to the issue. Prior to reporting this to my support partner, I wanted to see if anybody here has seen this before or give me some ideas to look into the source of the issue.
Full error message: Microsoft SQL Native Client SQL Server Invalid length parameter passed to the RIGHT function. (CINF)

Checking the list of form ID's at [http://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/892] shows the A/R Credit Memo as 179 and the A/P Credit Memo as 181. This also corresponds with what I see when viewing the system information on the form.

Parameter passing from master to subreport

Is it possible to pass a multi-value parameter from a master report to one or more subreports? If so, how?
Thanks for any help.
Wayne E. Pfeffer

Yes you can do this. I suggest the following: In your subreport make the report parameter a multi-value parameter. Test the subreport stand alone and make sure it works. Then drop the subreport into your main report, and map the subreport parameters to the main report parameters.
Scenario 1 (multi value parameter pass through):
The Main report has report parameter A which is a multi value parameter. You want to pass it to SubReport1 which has a report parameter B which is also defined as multi value parameter. In this case the mapping is just a simple parameter expression: =Parameters!A.Value
The subreport RDL element would look like this:
          <Subreport Name="SubReport1">
            <Parameters>
              <Parameter Name="B">
                <Value>=Parameters!A.Value</Value>
              </Parameter>
            </Parameters>
          </Subreport>
Scenario 2:
The Main report has no report parameters. You have a SubReport1 with a report parameter B defined as multi value parameter. You want to pass e.g. three selected values "A", "B", "C" as parameter values to the subreport. You need to create a multidimensional object array on-the-fly, e.g. with the Split function, e.g.: =Split("A,B,C", ",")
RDL example:
          <Subreport Name="SubReport1">
            <Parameters>
              <Parameter Name="B">
                <Value>=Split("A,B,C", ",")</Value>
              </Parameter>
            </Parameters>
          </Subreport>
Scenario 3:
The Main report has a multi-value parameter A. You want to pass only the first selected value from the main report's parameter to the subreport and the subreport's report parameter B is a single-value parameter. You can do this by using e.g. =Parameters!A.Value(0)
RDL example:
          <Subreport Name="SubReport1">
            <Parameters>
              <Parameter Name="B">
                <Value>=Parameters!A.Value(0)</Value>
              </Parameter>
            </Parameters>

Move jsp code into servlet, not work!!

Hi:
I am new in servlet and java, I can use jdom to read xml file
into a jsp file, but whan I move jsp code into servlet, they are not work
have any ideals?
Thank!

Hi:
my.jsp
<%@ page contentType="text/html"%>
<%@ page import="java.io.File,
java.util.*,
org.jdom.*,
org.jdom.input.SAXBuilder,
org.jdom.output.*" %>
<%
String Records = "c:/XMl/Quotes.xml";
SAXBuilder builder = new SAXBuilder("org.apache.xerces.parsers.SAXParser");
Document l_doc = builder.build(new File(Records));
my servlet
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
import org.jdom.*;
import org.jdom.input.*;
import org.jdom.input.SAXBuilder;
import org.jdom.output.*;
public class XmlJdom extends HttpServlet
String Records = "c:/xml/Quotes.xml";
SAXBuilder builder = null;
Element Author = null;
Element Text = null;
Element Date = null;
* Initializes the servlet.
public void init(ServletConfig config) throws ServletException
super.init(config); //pass ServletConfig to parent
try
// JDOM can build JDOM trees from a variety of input sources. One
// of those input sources is a SAX parser.
SAXBuilder builder = new SAXBuilder("org.apache.xerces.parsers.SAXParser");
catch ( org.jdom.JDOMEXception e)
public void doGet(
HttpServletRequest request,
HttpServletResponse response)
     throws IOException, ServletException
     PrintWriter out = null;
     out = response.getWriter();
     try{
     Document l_doc = builder.build(new File(Records));
Element root = l_doc.getRootElement();
//get a list of all recode in my XML document
String l_pages = root.getChild("quote");
String Iterator e = l_pages.iterator();
while ( e.hasNext())
Element l_quote= (Element) e.next();
     Element l_Author = l_quote.getChild("Date").getChild("Text");
XMLOutputter l_format = new XMLOutputter();
String ls_result = l_format.outputString(l_doc);
out.println(ls_result);
catch( org.jdom.JDOMException e )
     finally
          if( out != null)
               out.close();
Please tell me, what is wrong!!!
Element root = l_doc.getRootElement();
/* get a list of all the links in our XML document */
List l_pages = root.getChildren("quote");
Iterator Myloop = l_pages.iterator();
while ( Myloop.hasNext())
Element l_quote= (Element) Myloop.next();
     Element l_Author = l_quote.getChild("Date").getChild("Text");
XMLOutputter l_format = new XMLOutputter();
String ls_result = l_format.outputString(l_doc);
ls_result = l_format.outputString(l_doc);
%>
<html><head><title></title></head>
     <body>
          <pre>
          <%=ls_result%>
          </pre>
     </body>
</html>

Get "#" from URL into servlet

Hi
I am writing a servlet which can check that the requested URL is having "#" or not.?
Let's say my URL is like, http://abc.com/#/efg/hij.jsp
As it is having "#' sign in the URL string, So I need to check the existence of "#" in requested URL.
My problem is when I write ..
StringBuffer url = request.getRequestURL();
String requestedURL = url.toString();
requestedURL only provides me the string before "#" i.e. http://abc.com/
I need to check if it has "#" or not with whole URL string.
Is there any way to check that into servlet.?

The # sign is a client side sign telling it to go to a bookmark with the name following the # sign. The # sign is not part of the requested URL, so you can't get it on the server side.
If you are generating URLs with the # sign and trying to make it do something you should re-think the design since the # sign is reserved for client side use.
Alternatively you could try to pass any URL that does have the # sign through java.net.URLEncoded.encode(theURL, "UTF-8") to see if you can then get it back on the server.

Invalid length parameter passed to the LEFT or SUBSTRING function, error on INSERT

I have a stored procedure that does a BULK INSERT of a csv file into myCSVTable then INSERTs records from
myCSVTable into myTable. The INSERT statement is giving me this error:

There is no LEFT or SUBSTRING function used in the procedure and there are no triggers on either table.
The procedure had been working fine until today, when I altered one of the CSV fields. The code which triggers the error is this:
INSERT [myTable]
SELECT * FROM [myCSVTable]
The weird thing is, the 1st record containing the changed field (mstr: 1000000000000000017 js: 372651 epi: 1) triggers the error, but the 2nd record containing
the old field value (mstr: 1000000000000000017 id: 020000007 epi: 1), does not.
There are only blank spaces in the 2 strings, no non-printable characters or anything like that. I'm confused.

A View of myTable was causing the problem.
