How can I access xml document from javascript whithin a JSP page

how can I access xml document from javascript whithin a JSP page?
I have a JSP that receives an XML document from a JavaBean, so I can access it within the entire JSP, but I need to access it from the javascript inside the JSP... and I have no idea how i can do this.
Thanks in advance!

The solution would only work on MS IE browsers, as other browsers do not support an XML DOM.
It can be done, but you would be stuck with using the Microsoft broswer. If that is acceptable, I have some example code, and a book recommendation.

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

HI,
Since webdynpros follows Model View Controller Architecture You can access EJBs in webdynpro(views/frontend) infact to connec to database uding JDBC you have to utilise EJB ( opening connection to database closing, and other Business functionality).See this link

How can I access video file from sd card on ipad2?

How can I access video file from sd card on ipad2?

Your iPad 2 will see the video if:
It's in a DCIM folder on the top level of the card (which is how most cameras do it)
It's name is 8 characters, no more, no less (CKDI9483 for example)
It's a format that the iPad will play
I've made mp4's of things, folderized them right and named them 'right' and can transfer them to my iPad, so you can use a computer to make the files conform to what the iPad will see.

Really not suitable.. The TC is a dumb hard disk in a router.. it is not a media server..
You can move your itunes library to the TC.. but if you do that.. one day the TC will die and take your library with it.. as well as giving slow response to every network device.. this is really not suitable.

HT1414 how can I access my contacts from my iphone backup

I backed up my iphone onto my imac. How can I access the contacts, or can I?

You can plug a new phone in and restore the backup from your computer. As has already been stated, however, contacts are NOT part of the backup. If they were restored when you restored your phone previously, they either had to come from an address book on your computer or a cloud service you were syncing to (Exchange, Yahoo, gmail, etc.).
Most likely, you set up the contact sync when you first got your phone and never thought about it again. Just because you don't actually open and use the address book on your computer doesn't mean it isn't there.
On Windows, look in Windows Address book or Outlook. If you had an Exchange account, Yahoo account, or G-Mail account (set up as Exchange), look at the contacts on the server.
Even if you could save contacts to the SIM, you would only get a small fraction of the information that can be entered for each contact.

(how) can I access Java APIs from web-page-hosted JavaScript?

Can I access Java APIs from a web-page via JavaScript if I have a JRE installed on the client machine? And if so, how?
Thanks in advance for your time and consideration.

John L. wrote:

And if so, how?As far as I can remember that was actually possible in the very first versions of Netscape because Netscape really wanted to pretend Javascript and Java were meant to be used together. But they soon removed that functionality. Can you guess why?
Because people were using the File/IO classes to easily steal or remove files on the harddrive, among other such niceties. You do NOT want to have such control from a web application. People will abuse it.

How can I access iCloud documents from my iPad and work on them on my iPad

How can I access and work on documents in the cloud on my iPad, not a computer

Thank you, I really appreciate your time, but I think I am after something the iPad won't do. I don't want to use a computer at all. I would like to open an iCloud doc using my iPad, work on it (on the iPad), then print or save it back into pages or the iCloud.
From your responses, it sounds like you have to use an iPad in conjunction with a computer, of some description, to work on documents in the cloud, the iPad alone will not let you do this.
So I guess the short answer is, I can't.
Thanks for your time and input.

Access payroll variables from custom payroll function

Hi All,
I have a requirement to create a custom payroll function that returns some data from IT0006 and IT0032.
I have written the code in PCBURZDE0, as the payroll is for Germany, it does read the data needed.
My question is, how I can access the variables specified for the function in the payroll schema.
Schema definition in PE01
Zeile     Fkt        Par1 Par2 Par3 Par4 D Text
000010 BLOCK BEG                              Fahrradleasing
000020 _DFRD &PRO GEN
000030 BLOCK END
If I double-click Par1 for function _DFRD (&PRO), then I see he two variables I should write the data to:
Zeile VarArg. FZ T Operation        Operation Operation Operation Operation Operation *
       -------------+---------+------------------+---------+---------+---------+---------+
000010                  AMT= PKWWRPRINT     *
000020           1     AMT= ENTKM PRINT
So, as I understand I should write the two variables PKWWR and ENTKM, I have the values in the function code, but I don't know how to access these variables.
Thanks for your help!

1 - PIT is a Function that is used in the Payroll Schema to "Process the Internal Table".
2 - You mentioned that you had created a Custom Function to read IT0006 and IT0032, and I only suggested to you that you could have that Custom Function generate Information WageTypes and save them in the Input Table where they could then be used in PCRs.
3 - I did not mention that you can read only one value through operation AMT, but I mentioned that using AMT=xxxxxx followed by AMT=yyyyyy means that the first statement is useless. On the other hand, using AMT=xxxxxx followed by AMT+yyyyyy and AMT+zzzzzz will result in the amount being the total of the 3 values.
4 - Please read some documents on Schemas, Functions and PCRs, such as in the Wikis on this site, and study your current Payroll Schema, it's sub-schemas, it's functions and the operations in it's PCRs. Note that t-code pe01, pe02 and pe04 can be used to find some documentation on functions and operations.
