Query string access in jsp

I want to access the query strings from this URL. http://localhost:8080/napstersBank/imageone.jsp?39,23
I tried javascript method window.location.search.substring(1); but i want to implement it in JSP due to security reasons.
How to extract the query string from the above URL.
Thank you in Advance

I am not sure of what exactly the question is.
Are you asking about how to access variables in JSP ? Or how to pass a parameter from an HTML page to a SWF ?
Here:
'meetingModule.html?roomURL=<%= roomURL %>&authToken=<%= token %>',
you are simply passing variable to the HTML page. From there you need to use javascript to parse the query string and pass the values to your SWF.
If you look at the ExternalAuthentication examples they all do something similar.

How do i pass a url with query string using the jsp:forward tag

This snippet of code gives a 403 error
<jsp:forward page="testpage.jsp?test=1" />
How do i rectify it?

Well better way to go about for the job is to use
setAttribute("name","value");method in the first page
and then in next page use method
String s=getAttribute("name");to retreive the value.
Url rewritting or using Query String has some disadvantages ,which are handled by above mentioned approach.

Query string error in JSP

Hi. I originally thought my problem was a javaScript problem but now realize it is a JSP problem:
I have a JSP calling another JSP (which is opened in a smaller window with javaScript) and it uses a query string for values. One of these variables in the string is a note the user enters and can contain anything. Problem is when they enter text with the '&' symbol, I'm getting a Null Pointer Execption as the receiving JSP interprets it as part of the query string.
How can I 'hide' these characters so the receiving JSP page doesn't try to process it?
Thanks in advance,
Mike

hi,
you could detect the string before you sent the string, check for the & symbol and replace it with something else, such as the html equivalent and then append it to the url and send it, on the other end read it and replace the symbol with the & to get it back without confusing the code. you would run into the same problems if the user enter = or possibly ? into the string, so try fixing it with a search and replace method.

Doget and query String

how to use "doget", any example for me reference.
if i would like to pass the variable by querystring, can i add the variable in URL like this:
go home
but how can i get the ID in query string in home.jsp???

1. I can't understand the line of code that you just gave
What are you trying to put as the query string is not clear to me. If you are thinking that that code will call the toString method on any ID object, then it won't
2. To access the value of the ID parameter in home.jsp, you can use scriptlets or EL
<%=request.getParameter("ID")%>
${param.ID}

Accessing the Query String parameter from a portlet

Hi!
I have developed a PDK portlet in Jdev 10.1.3.3 for Web Center (Just for testing, later it'll go on Oracle Portal 10.1.4). I am trying to access the query string parameter coming in the URL but not successfull at all. Following are the options that I have tried in vain :
In MyPDkPortletShowPage.jsp with *<passAllUrlParams>true</passAllUrlParams>*
1.) PortletRenderRequest pReq = (PortletRenderRequest) request.getAttribute(HttpCommonConstants.PORTLET_RENDER_REQUEST);
pReq.getParameter("data");
2.) request.getParameter("data");
3.) request.getAttribute("data")
This makes me ask that is there any other way to access the parameter or is it simply not possible?
Please suggest!
Regards,
Neeraj.

Hi Neeraj:
I didn't deal with web center before i am working on Oracle Portal 10.1.4 so if you done that on oracle portal and got the same problem check for this?
- add the parameter in the page parameter then you will get the value from either preq.getParameter or from request.getParameter,just go to page properties and add a page
parameter called data
- did you publish your page containing your portlet as portlet and included it in other page or it is just a page containing this portlet?

JSP HTML Query String

Hi I am using query strings to pass variables such as groupName=Bonza.
However, I don't want the user to see this string so i was wondering if there is a simple way for the JSP or HTML page to encrypt or hide or mangle the query string, so instead of:
http://localhost:8080/jsp/newGroup.jsp?groupName=Bonza
i could have:
http://localhost:8080/jsp/newGroup.jsp?7thsgs7393j38dx
Something like that anyway, at least so i could decrypt at the processing JSP page. The information doesn't need to be secure, just so ppl can't see the names of groups and change the query string.
Thanks!

A few ways you can do this is to:
1) Use a form and specify POST to pass the data to the next page. The HTTP specification calls for passing the data in the header.
2) Use hidden fields on the page.
3) Use JSP sessions and use a bean to access the data from any page in your application implementing session.
The last method is prbably the better method and is what I used for my recent application. This requires that the client accept cookies so that you can track the user session. The first 2 do not.

C:import tag - Query string while calling servlet from JSP

Hi,
From my JSP I am calling a servlet to write back to the response stream of the JSP. From the JSP i am trying to pass some values into the query string as follows
     <%
     String strGetParameters = "/servlet/MyServlet?path=" + strPath;
      %>
     <pre><c:import url="<%=strGetParameters%>" /></pre>In the servlet I try to get the path from the query string by using
request.getParameter("path")But in the servlet the query string doesnt have the "path" parameter that I added in the strGetParameters string (in the JSP).
Am i missing something? Do i have to use something else or do something else?
Any help is appreciated.

Here is the test code, it was tested in Java EE 5 + JSTL 1.2 + Tomcat 6.

Jsp:forward param not getting included in my query string

Hi,
On a particular JSP page, mine.jsp, I am forwarding to a servlet ...
<jsp:useBean id="HotelResortDBBean" class="com.lvcva.database.HotelResortDBBean" scope="request" />
<jsp:forward page="/meetings/meeting-venues/results">
<jsp:param name="sqftRange" value="${empty param.meetingsqft ? -1 : param.meetingsqft}" />
</jsp:forward>This forwards to a servlet, when I query "request.getQueryString", it comes up null. However, when I enter the URL, "mine.jsp?sqftRange=-1", the query string returns "sqftRange=-1" as expected. Can someone tell me what I'm doing wrong in the above that is causing the jsp:param to not be added to the query string?
- Dave

a forward does not create a new request, and thus the query string is not altered. If you want the query string to change, use a redirect in stead.
note: even though the query string does not change, the new parameter IS added to the HttpServletRequest object, so you can still fetch the new parameter from it even with the forward.

SQL Query string in VBA Access 2010

Hi everyone,
I am writing sql queries in VBA Access 2010.
Now, i am very new to VBA programming, so i don't know how i have to write te string for the query.
I mean, are the " a,d _& sings in the good place?
The query sits behind a button on the form and when i use the form and click on the button i get the following error
This is the code i wrote:
Option Compare Database
Option Explicit
Private Sub Knop9_Click()
Dim bedrijf As String
Dim startdatum As Date
Dim einddatum As Date
Dim aantal_uren_jaarlijks As Double
Dim gevolgde_uren As Double
Dim resterende_uren As Double
Dim naam As String
'Voeg de waarden die ingevuld werden in het form in de variabelen
Tekst1.SetFocus
bedrijf = Tekst1.Text
Tekst3.SetFocus
startdatum = Tekst3.Text
Tekst5.SetFocus
einddatum = Tekst5.Text
Tekst7.SetFocus
gevolgde_uren = Tekst7.Text
Tekst11.SetFocus
naam = Tekst11.Text
CurrentDb.Execute "UPDATE Lan_landmeter " _
& "SET OpleidingsBedrijf =" & bedrijf & " ,Opleiding_startdatum =#" & startdatum & "#,Opleiding_einddatum =#" & einddatum & "#,Aantal_opleidingsuren_vast=20,Aantal_gevolgde_uren =" & gevolgde_uren & ",Aantal_resterende_uren=0" _
& "WHERE Id_landmeter =" & naam & ""
CurrentDb.Close
End Sub
Did i wrote the query string right?
Thx

In Access create a View showing the information you want, then in design mode click View, SQL to see teh SQL you need. now make sure the SQL you build in VBA is exactly the same. so in the Immediate window type a ? then copy paste your code then press Enter
to see the result, EG:
?"UPDATE Lan_landmeter " _
& "SET OpleidingsBedrijf =" & bedrijf & " ,Opleiding_startdatum =#" & startdatum & "#,Opleiding_einddatum =#" & einddatum & "#,Aantal_opleidingsuren_vast=20,Aantal_gevolgde_uren
=" & gevolgde_uren & ",Aantal_resterende_uren=0" _
& "WHERE Id_landmeter =" & naam & ""

How to access FlashVars or URL Query String

I am a bit of a rookie with Flash/AS3 and I need help trying to access FlashVars or URL in Object/Embed tags. I've searched in the Internet and the forums but cannot get my head around how to implement this. Here is my example.
1) ACTION SCRIPT - I have created a simple flash banner with clickable button (sparkle) with a mouse down event.
The action script (AS3) for the button is the following:
sparkle.addEventListener(
    MouseEvent.MOUSE_DOWN,
    function(evt:MouseEvent):void {
        var url:String = "http://www.[site_url].com/as/img.cfm";
      var request:URLRequest = new URLRequest(url);
        var variables:URLVariables = new URLVariables();
        variables.gphc = "382";
        request.data = variables;
        request.method = URLRequestMethod.GET;
      navigateToURL(request);
     *** the core issue to resolve is how to make the line above (variables.gphc = "382";) to be set dynamically. I would like for the variable to come from the FlashVars or the URL vars
2) OBJECT/EMBED - my object/embed code with include FlashVars and URL Query String
<OBJECT classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" ID="bannerAD" WIDTH="728" HEIGHT="90">
     <PARAM NAME="movie" VALUE="http://www.[site_url].com/images/imgs/flash_ad.swf?gphc=382">
    <PARAM NAME="quality" VALUE="high">
    <PARAM NAME="bgcolor" VALUE="#FFFFFF">
    <PARAM NAME="FlashVars" value="gphc=382" />
    <EMBED src="http://www.[site_url].com/images/imgs/flash_ad.swf?gphc=382" quality="high"WIDTH="728" HEIGHT="90" TYPE="application/x-shockwave-flash" PLUGINSPAGE="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Version=ShockwaveFlash" FlashVars="gphc=382" />
</OBJECT>
Questions that I need answered ... How do we access the FlashVars or the URL Query String? I have found many references to loaderInfo but no clear way to implement that I'm able to understand. So if the loaderInfo is the key, where do I add in the loaderComplete() function into my action script above in #1?
function loaderComplete(myEvent:Event)
var flashVars=this.loaderInfo.parameters;
gphcTextField.text=flashVars.gphc
this.loaderInfo.addEventListener(Event.COMPLETE, loaderComplete);
Any help is much appreciated.

Thank you for your input. I implemented your sugguestion in the following way without any success. Notice below in the addEventListner that I have added the snippet of code. Is this a good place (correct place) to set the local_var? I did confirm that the FlashVars and URL variables were set.
sparkle.addEventListener(
     MouseEvent.MOUSE_DOWN,
     function(evt:MouseEvent):void {
         var url:String = "http://www.[site_url].com/as/img.cfm";
         var request:URLRequest = new URLRequest(url);
         var variables:URLVariables = new URLVariables();
         var local_gphc:String = LoaderInfo(this.root.loaderInfo).parameters.gphc;
         variables.gphc = local_gphc;
         request.data = variables;
         request.method = URLRequestMethod.GET;
       navigateToURL(request);
Thank you for your help.

Example to use Query String in Oracle Access Manager Policy.

Hi All,
Can any one please tell me what is the use of Query String and Query String Variable in OAM Policy?
If possible please explain with a sample example.
Thanks in Advance.
Siva Pokuri.

Query string is used to protect URL with complete query string.
Ex: in case you want to protect http://hi.com/first.html?uid=abc&pqr=123 URL then you will specify query string as uid=abc&pqr=123.
In case you want to protect a URL with one of the query parameter as xyz and you do not care of other query parameters, then query string variables are used.
Ex: in case you want to protect http://hi.com/first.html?uid=abc&pqr=123 and http://hi.com/first.html?uid=abc&pqr=456 both with same policy then you will create a policy to protect first.html and in query string variables you will specify uid=abc.
Let me know if you have any problems in understanding this.
Thanks

Unwanted Query string appears in Apache access log file

hi,
i tried with the follwoing code to send the request for a servlet.
uri = "/servlet/Participant";
res.sendRedirect(getScheme( req ) + req.getServerName() + (req.getServerPort() == 454 ? (":" + req.getServerPort()) : "") + uri);
Here i am not appending any QueryString. But the log entry in Apache2 HTTP Server dispalys the QueryString apeended. Below is the log entry.
Host name - - [12/Apr/2009:23:58:58 +0100] "GET /servlet/Participant/?login.userid=mullapati&login.password=venkat12345 HTTP/1.1" 500 1274
any thoughts how it is happening?
Thanks,
Venkatesh

when u do a HttpServletResponse.redirect(url), the server merely sends a HTTP 307 response (Temporary Redirect) back to the client together with the url (which is what you formed up).
It is up to the client to make a second request to the server at the redirected URL. Your client (whatever it is, browser, etc) could be appending the query string at the end of the URL.

Database access in JSP?

Can I easily access MS access using JSP? If it is, what kind of drive should be used to access the MS Access database?
Thank you so much!

<%!
// define database parameters
String host="localhost";
String user="";
String pass="";
String db="";
String conn;
%>
<%
Class.forName("org.gjt.mm.mysql.Driver");
// create connection string
conn = "jdbc:mysql://" + host + "/" + db + "?user=" + user + "&password=" +
pass;
// pass database parameters to JDBC driver
Connection Conn = DriverManager.getConnection(conn);
// query statement
Statement SQLStatement = Conn.createStatement();
This is when accessing a database in a JSP, not a javabean... Try searching this forum, there are LOTS of topics about this.

Query string is null while dispatching the request in Websphere for Endeca pages

Hi,
When AssemblerPipelineServlet forward the request with dispatcher the query string is missing from the request in Websphere 7.0 only(works fine in JBOSS).
This is happening only for the pages those are created in the Experience Manager.
Ex: /store/us/detail?A=1204455 - This URL will render the /cartridges/ProductDetail/ProductDetail.jsp page. When we access the /OriginatingRequest.queryString in the JSP, it is giving null.
Please help us to resolve this issue.
