Need help with accesing variable with xpath.

Hi All,
I need help with xpath in "Switch" BPEL construct. Switch is used to compare value assigned to output vairable and follow one path for "Deny" and another for "Approve". The following is data type for output variable.
<element name="processResponse">
     <complexType>
          <sequence>
               <element name="result" type="string"/>
          <sequence>
     <complexType>
</element>
The following expressions in Switch statement throw lava.lang.Exception. It error is xpath internal error".
x20:compare('Deny',$outputvariable.payload/client:result)
x20:compare('Deny',bpws:getVariableData('outputvariable','payload','/client:processResponse/client:result')
It works with x20:compare('Deny','Deny'). So I assumed it must be accessing the variable.
Any help greatly appreciated.
Thanks,
Satish

Cany you try the following
x20:compare('Deny',string($outputvariable.payload/client:result))
x20:compare('Deny',string(bpws:getVariableData('outputvariable','payload','/client:processResponse/client:result'))

Need help on struts configuration with ColdFusion 10 using IIS

We need help on struts configuration with ColdFusion 10 using IIS.
Earlier we were using ColdFusion 8 with IIS 6 for one of our application. This application internally calls struts. After upgrading to ColdFusion 10 struts calls are not loading. We get 404 error.
In ColdFusion 8 struts were configured using actions extension .do in IIS from this file-
C:\ColdFusion8\runtime\lib\wsconfig\jrun_iis6.dll.
But in ColdFusion 10 this file is not present as ColdFusion 10 uses Tomcat in place of Jrun.
Also there is no information in ColdFusion log file.

doctormirabilis, Welcome to the discussion area!
1) how can i configure the time capsule in order to operate as a remote base station synchronizing with the relay using the ethernet port?
Configure the Time Capsule to act as a bridge (not distributing IP addresses). Also configure the Time Capsule to create an 802.11n wireless network with a unique network name (SSID). That's it.
2) how can i avoid that my powerbook while accessing my wireless network does connect through the relay station instead of using the time capsule?
Configure the Time Capsule to use a different network name than the WDS link between the 2 AirPort Express (AX). Configure the PowerBook to use the Time Capsule network.
There are 2 pieces of information that you should be aware of...
(1) None of the PowerBooks are capable of 802.11n.
(2) The WDS link cuts your available bandwidth in half. So the wireless link to your neighbor's has a maximum potential of 27 Mbps.
Let's for a minute assume that you have a Mac compatible with 802.11n. In your configuration the time you could take advantage of the 802.11n speed is when the Mac is sending/recieving data directly from/to the Time Capsule.
There would be NO speed increase in Internet access. The speed of Internet access is going to be controlled by the slowest link in the path to the Internet. That is probably the connection to the ISP. The next slowest path is the WDS link to your neighbor's.
Duane,
I am in a similar situation, sharing internet with my neighbor. Do you think it would be plausible to hook up a vonage phone adapter to time capsule's ethernet port if time capsule is bridging from my neighbor's router in the configuration you have described? A check of my upload speed shows 1.67Mbps (powerbookG4 w/ airport extreme). Vonage reccommends 90kbps minimum upload speed. Am I going to lose some speed putting the Vonag adapter behind time capsule?
Thank you

Need help re-synching iPods with new computer and getting iTunes to...

Need help re-synching iPods with new computer and getting iTunes to recognize our iPods (it doesn't even recognize them when they're plugged in).
Hubby wiped my harddrive for me, so now I need to get everything back in proper places. I'm using windows XP and installed iTunes once again (I believe it's version 8). I also installed all of my iTunes songs. Now I need to know where to go from here. We have 3 iPods and I need to get them all synched once again. I know how to create different libraries for each of us, but I can't figure out how to get our songs back into our iTunes libraries. When I open iTunes and plug in an iPod, iTunes doesn't even show that an iPod is plugged in.
What do I do now to get each of our iPods synched with our own libraries?
TIA
Brandy

Thanks Zevoneer. The "Restart ipod service" worked and itunes is now recognizing my ipod! Hooray!
Okay, now how do I synch all of our ipods with our individual libraries (I don't want all of my kids' songs and vice versa)? We each have hundreds of songs on our ipods that we don't want to lose.
Thanks again!

BW 3.5 - Issue with formula variable with replacement path

Dear experts,
I'm facing an issue with formula variable with replacement path.
Just to clarify, I know replacement paths is raising a lot of questions but I've been using this functionnality extensively in the past, both in 7.0 and 3.5, so I'm not looking for basic information about how to use it.
I'm trying to setup a simple report that would show total values per plant of Purchase Order < 100
To do so I've setup a calculated key figure as follow:
VAR1 * ("PO value" < 100 ) * "PO value"
VAR1 is a formula variable with replacement path on 'purchase order' and value attribute 'constant =1'.
(The report has to show values summarized by plant but should not show the detail PO by PO, so I'm not looking at a solution based on condition)
The report as characteristic "plant" in rows and my CKF in columns.
Now let's take an example. I have 3 POs in Plant 1:
PO1 -> 150
PO2 -> 90
PO3 -> 80
Because of the variable with replacement path, the result in my query should be:
plant1 = 170 (even though characteristic "purchase order" is not in my rows, system should evaluate PO one by one and return values only for those two that are below 100).
But the result coming is 320, which is wrong.
I've done the same report on many other 3.5 systems and it worked perfectly, and I am not able to get proper support from SAP OSS who keep saying that this functionnality is not ready in 3.5 (although I've provided screenshot of this working on another 3.5 system!!! how frustrating...)
They have also pointed to problems of Before and After aggregation but that has absolutely no impact. Once again, the scenario is working perfectly on other 3.5 systems with the same query design, so i'm sure it has nothing to do with Query Designer options.
Would anyone have ever come to an equivalenet problem? I'm wondering whether the DB itself could not play a role in the variable with ref characteristic 'constant =1' ...
Any though is welcome!
thanks

Hi,
The text variable is replaced when the exact date is clear for this key figure column according to the restriction.
To achive this, please make sure that either the variable is directly restricted in the key figure selection, or that the date characteristic is in drilldown.
Regards,
Patricia

Need help to create report with jpeg/gif image

Hello,
I need help with creating a form with a special jpeg/gif seal. I never done this Java. Until now, I created all forms with ansi C++ with HP escape characters to draw lines, boxs, and text. This form will contain boxes which is populated with database information read from a text file.
Since this form contains a special seal on the upper right, I don't think it can be done with old fashion ansi C++. How can I create a form with Java and create it as a simple exe to just print the form to a specified printer.
Thanks,
John

Hi,
I am creating a form with boxes (lines and text). What is special about this form is that it has an image jpeg or gif at the top right corner. Is is a state department seal. Up to this form, I had used ansi C++ and print out escape HP character to print out the lines, boxes, and text. I have no idea how to print out the image. I am new to JAVA and only 1 class in it. Is there sample code out there to create this type of form with the image? I need a starting point.
Thanks,
John

Need help - I2C write/read with TAOS TCS3414 light sensor using USB-8451

Hello, I'm new to labview and need help setting up a vi that will allow me to communicate with a digital light sensor (TAOS TCS3414) using a USB-8451. I need to use the sensor to measure light from a light source that I designed and built as part of a project im working on. I've tried looking at several labview I2C exampled but find them to be very confusing. I've used an arduino to interface with the sensor successfully but need to use labview and dont understand how to write the program. The actions are simple; I need initialize the sensor with a simple command and then request data from 8 data registers and then read that data. The data will then be used in further calculations. The portion i need help with is writing and reading from the sensor. I've attached the datasheet for the sensor as a guide. I can also provide the arduino code that i use to read data from the sensor if that would help.
Pleae keep in mind that i am completely new to labVIEW. I really do want to learn from this but need quick results so the more help the better. It would greately appreciate any help or explaination.

New and need help - drag and drop with dynamic text

So I'm doing this project and as an animator I'm not familiar with the whole action script side of flash
Okay so far I've managed to create the whole Drag and Drop feature and it works well, the thing is I want to make it so when you drag in object in the correct spot and new text appears, and I need like six different object with the dynamic text. but I have no idea how to integrated it in my code or where I should start!
So i based myself on some tutorial so theres some code in there that had dynamic text, but not exactly what i wanted
Your help would be much appreciated!
This is my code:
var counter:Number = 0;
var startX:Number;
var startY:Number;
six_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
six_mc.addEventListener(MouseEvent.MOUSE_UP, dropIt);
five_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
five_mc.addEventListener(MouseEvent.MOUSE_UP, dropIt);
four_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
four_mc.addEventListener(MouseEvent.MOUSE_UP, dropIt);
three_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
three_mc.addEventListener(MouseEvent.MOUSE_UP, dropIt);
two_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);
two_mc.addEventListener(MouseEvent.MOUSE_UP, dropIt);
one_mc.addEventListener(MouseEvent.MOUSE_DOWN, pickUp);

event.target.parent.addChild(event.target);
startX = event.target.x;
startY = event.target.y;
function dropIt(event:MouseEvent):void {

var myTargetName:String = "target" + event.target.name;
var myTarget:DisplayObject = getChildByName(myTargetName);
if (event.target.dropTarget != null && event.target.dropTarget.parent == myTarget){
    reply_txt.text = "Good Job!";
event.target.removeEventListener(MouseEvent.MOUSE_DOWN, pickUp);
event.target.removeEventListener(MouseEvent.MOUSE_UP, dropIt);
event.target.buttonMode = false;
event.target.x = myTarget.x;
event.target.y = myTarget.y;
} else {

four_mc.buttonMode = true;
three_mc.buttonMode = true;

Code help for formula variable with processing type customer exit

Hi Gurus,
I need help in user exit code. I am calculating a formula variable ( demand variability) in the user exit for a range of values given in the selection screen ( i.e processing based on the values given I_STEP = 2).
i am able to populate the E_T_RANGE table but the output is sending a single value output.
Expected Output
Plant ( sel screen Input) I Material ( Sel screen Input) I Demand Var(calculated O/P)
1800   I 12345 I   0.609
1700 I   21355 I   1.234
Actual Result
Plant ( sel screen Input) I Material ( Sel screen Input) I Demand Var(calculated O/P)
1800   I 12345 I   0.609
1700 I   21355 I   0.609(WRONG )
Here you can see that its sending the same values for all the plant and material combination.
I found in debugging that it populates 2 values into E_T_RANGE table in loop. But it is giving out only one value to all.
I tried to refresh and clear that but its giving the same output. Can we use E_T_RANGE in loop to give out range of values?. how to out put this throught user exit?
did anyone face this kind of issue and solved it?. Help is needed urgently. any help or guidance is greatly appreciated.
Regards
satish.

Hi Oliver,
Thanks for the reply. Dont get confused here please. It was an example . For example
I give one plant as input and 2 materials as input .
You see the sample code :
WHEN 'ZPRDEMVA'. ( formula variable name)
    IF i_step = 2.
      LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE
              WHERE VNAM = 'ZPRPLTSV'. ( plant variable input)
      CLEAR L_S_RANGE.
        v_werks          = LOC_VAR_RANGE-LOW.
      LOOP AT I_T_VAR_RANGE INTO LOC_VAR_RANGE
              WHERE VNAM = 'ZPRMATSV'.
      CLEAR L_S_RANGE.
        v_matnr          = LOC_VAR_RANGE-LOW.
CALCULATES THE FORMULA VARIABLE (DEMAND VARIABILITY)
WE TAKE DATA FROM ANOTHER ODS AND DOES CALCULATION.
      l_s_range-sign = 'I'.
      l_s_range-opt = 'EQ'.
      l_s_range-low = sum2.
DOES ALL CALCULATIONS PERFECTLY AND SINCE THERE ARE 2 MATERIALS AS INPUT, PUTS 2 VALUES IN E_T_RANGE. BUT IN THE OUPUT IT DUPLICATES SAME VALUE TO 2 RECORDS AS I POSTED IN THE FIRST
      Append l_s_range to E_T_RANGE.
      ENDLOOP.
      ENDLOOP.
    ENDIF.

Need Help some WPA2 problems with only certain Macs

I've done some searching on the various forums here but can't quite find something that fits the issues I'm having.
We've got 4 Macs on a home wireless network. The specific models are:
iMac 20" Core2Duo
12" PB 1.33Ghz
12" iBook 1.2Ghz
Mac Mini G4 1.42 Ghz
We use to run WPA on a D-Link router (DI-624) and everyone could connect just fine. Then with 10.4.8 all of the sudden my iMac started to have major issues connecting to the wireless network. I did a bunch of reading and found most people saying it was related to using WPA instead of WPA2.
So I went ahead and updated my firmware on the router (it now handles WPA2) and am in the process of getting all the computer back online. I've changed both the network name and the passphrase (and am using WPA2 Personal with AES) and have then set up the new network name along with WPA2 Personal and the correct passhphrase as a Preferred Network on all the machines.
However...
Only the iMac connects to the new WPA2 network.
Both laptops and the Mini have an AirPort Extreme card with firmware version 405.1 (3.90.34.0.p18).
What gives? From what I've read these airport extreme cards should be able to work with WPA2. Oh and all the machines are running 10.4.9.

Need Help ASAP!! with iPod Classic 80GB

This is my first apple product and it is not giving a good impression. I need help eargently!
I Sync 2969 songs onto my ipod for first time 2 days ago using latest Itunes it worked great and i was happy just my ipod didnt have all the album art, so the next day i plugged it in and put all the album art to the correct albums which went fine, then i wanted to add another album. I clicked sync to update the library on my ipod and it started transfering at a sluggish speed simular to this 1....2....3....4....5....6 etc it eventually got to 196 out of 1248 and stopped and 2 mins later itunes crashed. so the only way i could remove my ipod was to pull it out without ejecting it i then tried to look for the songs and what do you know it said on my Ipod 0 Music..... I was gob smacked i put it back in, in hope for it to sync again but ever since then it continues to do that, but i can manually transfer max 4 albums by drag and drop, at a time before itunes crashes. I am seriously going to throw it in the bin soon if i cant get it working and i will never ever buy an apple product again, i love the idea of the iPod but there to faffy! compared to a standard MP3 player..
PLEASE HELP ME i have tried restoring it many times, ive tried resetting it holding menu button and select button. and i have also tried another way were you restard the ipod and during the apple logo you quickly hold play which formats it..
please help me!! apples help lines are useless!

You do understand that this is a user-to-user forum? That we're all volunteers? And this is a weekend? You may need to be a bit more patient.
If I had an answer I would be happy to try to help. When you say you've tried "restoring" it, do you mean that you've hooked it up to your computer and pressed the "Restore" button in iTunes? If not, that's the next thing you should try.
I know you've tried a few things but it wouldn't hurt to go through the standard trouble shooting steps:

Best of luck.
