Modify the footer with java-script
Hi,
Im' trying to modify the content of the footer in the master-page using java-script. So I put in the initialize event of the footer code to add "!" after a text field (with plenty of space left) but it doesn't do anything. The code is example.rawValue = example.rawValue + "!";
This code works fine in the rest of the document, but it doesn't seem to work in the master-page.
Could somebody tell me what I'm doing wrong?
Thanks in advance!
Gert
The access to the masterpage objects is not in the same scope as where the script is running so you must path to it starting from the root:
so.... form1.pageSet.Page1.example.rawValue = form1.pageSet.Page1.example.rawValue + "!";
where form1 is the root node of your form (look in the hierarchy view), pageSet indicates the objects in the Master Pages, Page1 is the 1st Page name in the Master Pages and exampel is the path to th erest of the object.
Make sense?

Problem with Java Script after upgrade from BW 3.5 to BI7
Dear Colleagues,
We're facing the issue with Java Script after upgrade of BW 3.5 to BI7.
Just after update we checked the basic functionality and it occured that some of web templates that use Java Script don't work. They generate seelction screen, but after selection the screen becomes blank without any error messages.
We're currently stucked since web templates weren't converted to BI7 version so they should work exactly as before the upgrade.
We compared the Java code with other environment that was not upgraded - it's perfectly the same.
The only explanation that comes to my mind is that some Java Script settings on the server level were changed during the upgrade but I have no idea where I can check that.
Thanks in advance for any suggestions,
Andrzej BobulaHi Deepu,
Thanks, it was great to read your reply and then few minutes later talk to you live on SDN Day!
Unfortunately, http cache clean-up did not help. But there is another funny thing I found - for exactly the same 3.5 webtemplate html code returned from WebAS 3.5 was different then from 7.0.
Unfortunately, this editor does not allow to paste complete code, even in CODE brackets, but here are main differences:
<b>3.5</b>
if (navigator.appName == "Microsoft Internet Explorer")
<frame src="/sap/bw/BEx?SAP-LANGUAGE=E&PAGENO=1&REQUEST_NO=1&CMD=GET_TEMPLATE"
name="Content">
and
<b>7.0</b>
if (navigator.appName.indexOf("Microsoft Internet Explorer")!=-1)
<frame src="/sap/bw/BEx?SAP-LANGUAGE=E&PAGENO=8&REQUEST_NO=0&CMD=GET_TEMPLATE"
name="Content" 0nLoad="javascript:loadTitle()">
(I intentionaly put 0 i/o o in 0nLoad, otherwise Forum's editor does not accept the text.
How about SAP's claim that technical upgrade from 3.x to 7.0 changes nothing?

I want to roll back to an earlier version Firefox that works with Java Script how can I do this. Where I can download an earlier version? You know what the problems are. I am NOT going to list them. Own up to your errors. You made an incorrect conscious decision to break with Java compatibility.
Mozilla is not lying about average users, but it shows contempt for experienced users, or those that want to be able to get the more out of their browser, or use it for work or school.
Java and JavaScript are not the same thing. I trust you are referring to JavaScript problems and a lot of collateral damage associated with the mess.
# Prohibition on Webpages being able to resize or move windows with JavaScript
# Prohibition on Users being able to move or resize windows with JavaScript
# Ignoring the fact that there were already user controls in Tools > Options > Content > Javascript > Advanced
# Making JavaScript inoperable from Location bar as a command, or in a keyword shortcut that involves moving resizing windows
# Destroying use of AwesomeBar search, Bookmark searching for bookmarks containing JavaScript, making internal searches very unreliable
Firefox 8 comes out November the 8th and it nor later versions show any reversal of this mess.
Firefox 3.6.* should remain safe to use for some time, as corporate users will not put up with nonsense when they support thousands of users.
For those that really need an older version of Firefox [ftp://ftp.mozilla.org/pub/firefox/releases releases] (all releases, including 4.0.1 and 5.0) or with the latest of [http://www.mozilla.com/en-US/firefox/all-older.html Firefox 3]. Mac OSX 10.4 users can't upgrade to 4.0.1
When you reinstall a different version, at the end of the install, don't let the install start Firefox for you, rather exit, and then start Firefox in the normal manner to avoid inadvertently creating and using a new profile without your bookmarks, etc.
What would be better would be to use multiple versions / profiles at the same time, which is certainly beyond average users, particularly when Mozilla has historically and purposely made such things difficult. But if interested see [http://kb.mozillazine.org/Using_multiple_profiles_-_Firefox Using multiple profiles - Firefox - MozillaZine Knowledge Base] -
Web site with Java Scripts ( on iphone4)
try to open a web site with Java scripts , but it just show empty on the scripts section , anyone can help ? (on iphone 4 with iOS 4.1)
Hi, welcome to Apple Discussions.
Web pages that make use of Javascript should work just fine. Those that have embedded Java applications won't. Java & Javascript are two different animals despite the similarity in the names. Like Flash, Java is not supported on iOS.

Problems with Java Scripting API
Hello Everyone!
Guys, I need help with Java scripting API. A problem is that I cannot understand how can I operate Java Object's fields and methods from the script language. I have chosen embedded javascript to work with. And I can get the fields and methods of in-box java classes (such as ArrayList for example), but I cannot work with methods and fields from my own classes!
Here is an example:
public class ScriptingExample {
class MyClass {
int myfield = 5;
int getInt() {return 7;}
public void runExample() {
ScriptEngineManager mgr = new ScriptEngineManager();
List<ScriptEngineFactory> factories = mgr.getEngineFactories();
ScriptEngineManager factory = new ScriptEngineManager();
ScriptEngine engine = factory.getEngineByName("JavaScript");
MyClass mc = new MyClass();
try{
engine.put("mc", mc);
engine.eval("print(mc.myfield); print(mc.getInt())"); // or engine.eval("print(mc.myfield)");
} catch (Exception e) {e.printStackTrace();}
} If I run the code with the commented part it prints "undefined" instead of "5".
If I run the code as it is it prints error instead of "7":
undefinedjavax.script.ScriptException: sun.org.mozilla.javascript.internal.EcmaError: TypeError: Cannot find function getInt. (<Unknown source>#1) in <Unknown source> at line number 1
at com.sun.script.javascript.RhinoScriptEngine.eval(Unknown Source)
at com.sun.script.javascript.RhinoScriptEngine.eval(Unknown Source)
at javax.script.AbstractScriptEngine.eval(Unknown Source)
at solutiondatabase.ScriptingExample.runExample(ScriptingExample.java:26)
at solutiondatabase.Main.main(Main.java:49)
How can I fix it?Guys,
please let me raise this topic because several new questions emerged.
(1) How can I get all the variables created inside my engine?
There are two kinds of variables: first kind is Java obejcts put inside the engine and second kind is the variables created in my script, such as 'var a = 4;'. How can I list all the variables of that two kinds?
(2) Is there is a way to make 'import static' to the engine? I dont want to write MyClass.MyEnum.MyEnumItem every time. Also, I cannot put the whole enum into the engine with engine.put("MyEnum", MyEnum); I can put only enum items separately: engine.put("MyEnum", MyEnum.EnumItemA);. Thats why I ask about static import.
(3) How can I cast engine variables back to java variables inside my java code?
Here is my example:
package mypackage;
import java.util.ArrayList;
import java.util.List;
import javax.script.ScriptEngine;
import javax.script.ScriptEngineFactory;
import javax.script.ScriptEngineManager;
public class Main
public static void main(String[] args) throws Exception
ScriptEngineManager mgr = new ScriptEngineManager();
List<ScriptEngineFactory> factories = mgr.getEngineFactories();
ScriptEngineManager factory = new ScriptEngineManager();
ScriptEngine engine = factory.getEngineByName("JavaScript");
ArrayList<Double> myList = new ArrayList<Double>();
myList.add(5.0);
engine.put("MyList", myList);
engine.eval("MyVar = MyList.get(0);");
System.out.println((Double)engine.get("MyVar"));
}The result is:
Exception in thread "main" java.lang.ClassCastException: sun.org.mozilla.javascript.internal.NativeJavaObject cannot be cast to java.lang.Double
+ at mypackage.Main.main(Main.java:28)+
Is it possible to retrieve my Double java object from the engine?

Getting the error access denied trying to modify the workbook with identifier in Disocverer Admin
Hi All,
I have exported a workbook created by business user as an .eex file logging in as discoverer admin from a Production enviornment (transactional databse) and trying to import it to a different environment called reporting environment ( non transactional databse) and getting a warning 'WFS GTP REPORT SINAPORE.eex:Access denied trying to modify the workbook with identifier 'WFS_GTP_REPORT_SINGAPORE'.
It says Files Partially Imported so clicked on Finish to complete the import.
The report has been imported under the user account but the sharing to the different responsibilities/Users has not been imported. I need to import the report with the sharing of the responsibilities/users as well.
I do not have an option login into discoverer administratore using the user account, i can only login using the administator account ( i know loging in as the business user it self will allow you to import the sharing). But our DBA's oppse this is a security threat for the users as you are logging in as the user in production environment.
Please help with this issue.I have the same problem, and I figured out that my windows is installed in french, and every users groups are created in french also, groups like Everyone don't exists and i can't change by console.

Issue with Java script associated with WAD template
Hi Experts,
I made some changes in the Java Script in Tcode SE80. I actually downloaded it, made changes, saved it and then clicked on Upload and replace in SE80. When I opened the Web cockpit, the changes were relecting as anticipated.
But the changes are still showing up even after reverting the changes in java scripts and uploading it again.Please let me know what needs to be done to revert the changes such that it will ot show up in the Web Cockpit.
I think the "Upload and replace option" worked only once in my case. Kindly suggest. Thanks
Regards,
Kavitha JagannathI would like to know how to do this process. I would like my students to complete the module and then enter there name in the certificate line. Then have them enter their email address so that the certificate can be emailed to them and they can print it off. I would like to have the certificate be a PDF file so they cannot alter the name of the person who took the course.

Hi,
I am writing a .jsp file. I am able to put value of jsp into my java script code like..
var i = <%= k %>
but, now my requirement is reverse. I need to put the value of java script variable i into jsp variable k.
Someone told me that it is possible using eval function.
Now, using eval function , I can do the following ...
function xyz() //java script function
eval(<% int k = 5; %>);
but, I need to put the value of java script variable i into k.
I tried eval(<% int k = %> + i);
but it is not working that way.
Can anyone tell me how can I achieve this? Please reply as soon as possible.
ThanksJust came across this, and even though it's old, I thought Id add something to it since I know a lot got problems combining javascript and jsp; and that most usually don't provide enough info to get someone started.
To be able to "use" Java variables inside a javascript, you need to pass them in the function call:
<%
String aVariableToPass = "tadaaaaa";
%>
<form onSubmit="myFunction(this,'<%=aVariableToPass %>')" method="post" name="myForm" action="">
<table>
<tr>
<td>
<input type="submit" value=HitMe" name="submit"/>
</td>
</tr>
</table>
</form>The function:
function myFunction(form, theVariablePassedIn)
var accessToTheVariable = theVariablePassedIn;
}Now use accessToTheVariable inside the javascript, or theVariablePassedIn directly if you please.
Cincerely. P -
Hi everyone.
I've been trying to learn how to make a web crawler in java following this detailed albeit old tutorial: http://www.devarticles.com/c/a/Java/Crawling-the-Web-with-Java/
The SearchCrawler class they feature can be found in two parts:
First part: http://www.devarticles.com/c/a/Java/Crawling-the-Web-with-Java/3/
Second part: http://www.devarticles.com/c/a/Java/Crawling-the-Web-with-Java/4/
I don't want to copy and paste the code because it is really long and an eyesore if viewing here.
I get a lot of errors when compiling of which I do not understand. The majority of the errors (62 of them to be precise) are "class, interface or enum expected" errors, with the remaining few being "illegal start of type" and "<identifier> expected" errors.
Can someone here perhaps take a look at it and compile it and see if they also get the same errors? I realise it is an old tutorial but there are hardly any detailed resources I can find for java web crawlers.
Thanks.Odd I can't seem to log into my account. Never mind.
I have used java before, the problem here I suppose is I'm not good enough to spot what's the problem. The code seems fine bracket wise and it has really left me stumped.
If someone code put it in their editor and attempt to compile and see if I'm not the only one that's having a problem.. that would be much appreciated.

Sreaming at the top of my lungs for HELP with Java Script problem!
Hello,
I have this strange problem that no one seems to know why or how to fix it.Whenever I encounter a web site that has java scripting for anything pop ups or redirects to url's anything that says java script when I mouse over the link my browsers do nothing.That is for explorer 6.0 beta netscape 4.7 and netscape version 6.I have tried in another forum some suggestions but nothing changed even though I am told nothing is wrong with the java scripting.I used to be able to click java script's with all of these browsers but no longer.That was a few months ago.Now to try something new I tried to see if a new browser would work.I now have the latest version of Opera.It did work but using Opera on some sites limits what I can do so it doesn't solve my problem.Then I tried the Sun JavaHot browser it also worked but limits what I can do on some site's.I have Windows 98 & updated most of my dll's etc & my java is version 2 1.3.1.My java script is enabled in Explorer & netscape's & the security is at a minimum level.Please help me figure out why these other browsers work but the other's do not.I want to edit a web site of mine but I can't because of this problem.I am very frustrated by this and need as detailed help as I can get.Anything of a suggestion would be very much appreciated.But I am also not an expert on the working's of a computer so bear with me.
BrianHi,
Well I am thinking that if anyone could know something about Java script it would be java developers.But anyways I had the previous version of explorer 5.0 & the java didn't work in it either.Now how weird is this,I opened netscape 4.7 today & the java scripts are suddenly working.This has me scratching my head wondering if my computer is possesed by some force beyond my capability to know...????Weird as it seems though the explorer still will not respond to a java script.

Set the value of an adf number slider with java script
Hi,
i develop a adf 11 webapplication with JDeveloper 11.
in one page i use the number slider component and i wish to set the value with a clientlistern in javascript.
is this possible??
thanks,
hannesHi,
did you try
slider = AdfPage.PAGE.findComponent("<sliderId>");
slider.setProperty("value",<your value>);

So , I edited the ITunes.java as described in the Admin guide.Copied the .class to my cgi folder in the server.I copied the itunesu file from the shell folder of the sample code.I have modified it accordingly.But when I run it in browser(Firefox) as ..../cgi-bin/itunesu it just gives me a blank page.Nothing shows up.I ran the ITunes.java file locally and it generates an HTML output, which I copied and created a new html.After I run this HTML file, it opens my itunes, but again it says page not found and url contains https://www.xxx.edu/cgi-bin/itunesu?destination=xxx.edu where xxx is my institution name.Not sure if I am supposed to display my institution name in forum.
The admin guide says on page 15 step 4.Copy the itunes.class file and other itunes file to your web server's cgi-bin directory.
I am not quiet sure what does other itunes file mean??

// the code below with "/API/GetBrowseURL/" if you instead want
// to return the URL that would need to be opened to have that

String prefix = siteURL.substring(0, siteURL.indexOf(".woa/") + 4);
String url = prefix + "/Browse/" + destination;
String results = iTunesU.invokeAction(url, token);
System.out.println(results);
The itunes file from Shell folder has been modified as follows
DISPLAY_NAME= "myname"
EMAIL_ADDRESS="[email protected]"
USERNAME="mylogin"
USER_IDENTIFIER="1243"
all the other things in that file have been untouched.
I also generated the debug which looks like this
iTunes U Access Debugging
Received
Destination xxx.edu
Identity "my name" <[email protected]> (mylogin) [1243]
Credentials Administrator@urn:mace:itunesu.com:sites:xxx.edu

Analysis
The destination string is valid and the corresponding destination item was found.
The identity string is valid and provides the following information:
Display Name my name
Email Address [email protected]
Username mylogin
User Identifier 1243
The credential string is valid and contains the following recognized credential:
1. Administrator@urn:mace:itunesu.com:sites:xxx.edu
The time string is valid and corresponds to 2007-12-03 18:34:33Z.
The signature string is valid.
Access
Because the received signature and time were valid, the received identity and credentials were accepted by iTunes U.
In addition, the following 2 credentials were automatically added by iTunes U:
1. All@urn:mace:itunesu.com:sites:xxx.edu
2. Authenticated@urn:mace:itunesu.com:sites:xxx.edu
With these credentials, you have browsing, downloading, uploading, and editing access to the requested destination.
I am pretty new to this, and working on this for the first time.If someone could guide me through this would be pretty helpful.This is only going to work under IE !
Go to your page template :
Modify the definition, make sur you have this :
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>#TITLE#</title>
#HEAD#
<Script language = javascript>
Browser = navigator.appName
Net = Browser.indexOf("Netscape")
Micro = Browser.indexOf("Microsoft")
Netscape = false
IE = false
if(Net >= 0) {Netscape = true}
if(Micro >= 0) {IE = true}
function XYpos() {
if (IE == true) {
xPos = event.screenX
yPos = event.screenY
alert(xPos + " left " + yPos + " down")
else if (Netscape == true) {alert("Script won't work: " + "\n" + "You're using Netscape")}
</script>
Modify the body definition, make sure you have this :
<body #ONLOAD# onMouseDown = XYpos()>
