Can JavaScript access JSP variable?

Could we do this? Or, how could we have JavaScript access JSP variable?
<%
String fooBar = request.getParameter(......
%>
<script language="JavaScript">

</script>

To access the variable in Javascript you'll have to
write it out from the JSP. You'll need to do something
like:
<%
String fooBar = request.getParameter(......
%>
<script language="JavaScript">

</script>You'll need to either make sure fooBar doesn't contain
any quotes or write a function to replace each ' with
\'.Thanks!
That works perfectly, without encodeQuote() method in my current case.
Thanks again. You ar a saviour.

Accessing JSP variables in Included Javascript

Hey All,
I want to hide my javascript to be viewed on the client browser.
I know we can do that with the javascript include ,But i am using JSP variables in
Included javascript.I can't access those variables any more.
Does anybody know any workarround.
Thanx
Vijay

Hi Vijay,
I am also facing the same problem of hiding javascript in the client browser. My javascript variables are getting initialised on the fly using JSP. Since JSP is compiled on the server side, one can't compile .js file on the client side.
What u can do is to divide your page into frames with
<frameset rows="100%,0%">. Now put your form hidden fields or the .js file in frame 2 which is not visible to the user and then assign your jsp variables in the frame2 html/jsp page. Now access your variables from frame2 in frame1 using
var i = parent.frames[1].document.forms[0].elements[0].value
Assuming that there is 1 form and 1 hidden field in frame2 html/jsp page.
I hope u get the logic rite....
I had done it for application but problem is that our users are real MORONS and they keep doing ctrl+F5 which takes them to the Indexpage.
If you get some other solution then please mail it to my email address

How can I access global variables in a loaded Applescript?

How can I access global variables in a loaded script, in Xcode, ApplescriptObjC? Basically, I have a global variable defined in my parent script using "property", and I need to modify objects connected to those variables inside of a loaded script.
Example:
Parent script:
script AppDelegate
property myTextField : missing value
//linked to a text field object
tell myScript to myAwesomeHandler_()
end script
Loaded script:
on myAwesomeHandler_()
myTextField's setStringValue_("The new Xcode is so glitchy ugh")
//changes value of linked text field of parent script
end myAwesomeHandler_
The problem is, the variable is undefined in the Loaded script, and I need it to have the same value as the parent script, and I don't want to pass the variable through the Handler. Any ideas?

I think want you are looking to do will need to be done in two steps. Because myTextField needs to be a property for the ObjectiveC part of the code you cannot turn it into a global.
However if you make a temporary variable global assign the string to it in the handler then set myTextField off of it.
global myTextFieldGlobal
script AppDelegate
property myTextField : missing value
//linked to a text field object
tell myScript to myAwesomeHandler_()
myTextField's setStringValue_(myTextFieldGlobal)
end script
on myAwesomeHandler_()
set myTextFieldGlobal to "The new Xcode is so glitchy ugh"
//changes value of linked text field of parent script
end myAwesomeHandler_
I know you stated you did not want the handler to return a value but I have to ask why? Global's, imo, are not a good idea and really should be used as a last resort.
One other possibility is to pass a reference to the property to the handler. Not sure if that works in AS of if that would satisfy our requirement of not passing the variable through the handler
<edit>
Another though have you tried to define the property outside the script? That is
property myTextField : missing value
script AppDelegate
Not sure if that will work.
You might also want to have a look at Scope of Properties and Variables Declared in a Script Object

Accessing JSP Variables in Custom Tag Handler.

Hi,
I am creating a custom tag which builds a list view. I have certain String array in my JSP and I need to pass the same into my Tag Handler class. I tried following ways :
1. In doStartTag() implementation I used
   public int doStartTag() {
         String[] myArray = (String[])pageContext.getAttribute("mystringarray", PageContext.PAGE_SCOPE;
   }This is not recognizing the String array variable defined in my JSP.
2. I used separate attribute which is passed from the JSP to the custom tag as parameter having "rtexprvalue" as true. But I cann't pass a Sting array into my tag handler class. I can pass only String.
How can I access variables which are defined in the JSP using declaration block. i.e.
<%!
String[] myArray = new String[100];
%>
Thanks for the time.

You should be able to pass any type you like as an attribute to the tag.
You just have to define its type as String[] in your tld:
<attribute>
<name>stringArray</name>
<required>false</required>
<rtexprvalue>true</rtexprvalue>
<type>java.lang.String[]</type>
</attribute>
Alternatively, If you declare your array like:
<%!
String[] myArray = new String[100];
%>You can do this:
pageContext.setAttribute("mystringarray", myArray);
which will put it into the page context for you to pick up in your custom tag.
Hope this helps,

Can I access Infoset variable from Crystal Reports

Hi,
In order to connect Crystal Reports 2008 to the SAP environment I have the Integration kit.
I have learnt that Crystal also offers InfoSet driver to connect to SAP.
If I need to access SAP BI- Infoset variables inside Crystal Reports is it possible to do that. If no, then do I need to have the filter using the variable value instead of the fixed filter value?
Please suggest.
Thanks,
Amogh.

Hi Amogh,
the InfoSet connectivity that Crystal Reports offers as a direct Infoset connectivity is towards the classic InfoSets from ERP.
see here:
/people/ingo.hilgefort/blog/2008/02/07/businessobjects-and-sap-part-i
/people/ingo.hilgefort/blog/2008/03/23/businessobjects-and-sap-part-4
In case you want to connect to an InfoSet in a BW system you would put a BW query on top of the InfoSet and then use the BW Query in Crystal Reports.

Please help.

Juan,
Please ignore my previous email.
I got it work after I tried "Loading BC4J Runtime Libraries to OC4J". But...
I have problem starting one browse JSP page. I created two browse JSP pages, and they are almost identical expect for referencing to different Oracle tables. Surprisingly one works fine while the one doesn't work and kills OC4J when I click to open. The error is the normal IE "The page cannot be displayed". It shows the page title for a second, and then gives the error and stops OC4J.
Do you have any ideas? Thanks.

Set Core Prefix , can value be a variable ?

<c:set var="foo" scope="session" value="bar"/>
<%
String varSet = (String)session.getAttribute("foo");
%>
For the above variable output is bar...simple
now instead of value = "bar"
can we have
String test = "bar";
<c:set var="foo" scope="session" value="${test}"/>
Is this possible ?

Sorry, JSTL can't access scriptlet variables directly like that.
You would have to use a regular jsp <%= expr %>
So if you have a JSP2.0 container, this would work:
<c:set var="foo" scope="session" value="<%= test %>"/>or this would work in any container (but only with string values):
<c:set var="foo> scope="session><%= test %></c:out>Cheers,

Accessing session variables

"145822",
If your application with application id 100, for example, uses a common authentication scheme with application 200 (using the same cookie name in the case of an HTML DB style authentication scheme), then the two applications can run in the same session. A potential benefit of this, even if the two apps are not intricately related, is that the user has only to authenticate once per new session and will have access to both apps. If you set it up this way, then app 100 can access app 200's items in the same session using this function from within app 100: htmldb.application.fetch_app_item(p_item=>'ITEM_NAME',p_app=>200);Scott

Accessing public variables from other classes

Probably a simple questions, but how can I access a variable from another class. My exact situation is as follows.
A class called WorldCalender has a variable which is defined: public int hour; (the value is given to it elsewhere).

don't expose the hour variable at all.
have a method eg addToHourBy( int hrs )

Accessing session variables with php

I am trying to access the session variable $_SESSION['MM_Username'] in one of my php pages, but it is somehow showing empty (i.e it does not contain the username that was entered during login).
I checked and confirmed that my login.php function is properly setting the MM_Username session variable by echoing it from the login function.
So why can't I read it from another php file in the same session? Do I need to do something else before the session variables can
be properly read from any php file in the same session? Any help would be appreciated.

Here is a test code I am using to access the session variable $_SESSION['MM_username'] from the php page test.php. But it is not working.
I get an empty string all the time for $username. Can any one see something wrong with this code?
<?php require_once('Connections/MyTestingConn.php'); ?>
<?php session_start(); ?>
<?php
$username = "-1";
if (isset($_SESSION['MM_username'])) {
$username = $_SESSION['MM_username'];
echo $username;
else
echo "Eror: can not access session variable";
?>

Forms 9i accessing package variables

I created a package in my sql session which contains only variables. When I connect to the database through Oracle Forms and try to access these variables in a trigger I receive the error "Cannot directly access remote package variables or cursor" How can I access these variables from within a forms module?

You cannot access package variable or constants directly from a remote PL/SQL client. Only PL/SQL running on the server can access these. You need to implement get and set methods in the package.
