Passing key to servlet

I'm trying to pass a rowkey from UIX to a servlet and having some difficulty. I think I'm converting the passed string to a Key value incorrectly.
I did
rowKey = Key(passedKeyString);
foundRows = view.findByKey(rowKey,-1);
What am I doing wrong?

You can just send it in text as a parameter.

Null values passed into the servlet

Hi all,
I keep getting null values for all the params that I pass into the servlet i.e. sqltype, producttype, process, instance etc....I have attempted to print some of them out on the screen but I keep getting the 'NullPointerException' error message...can anyone tell me what it is that I have down wrong in the below code?
If I run the servlet with method calls that have hardcoded arguments in them it works but not when I pass in the params from the URL...I am absolutley puzzled!

}

That section of the code references a cache to extract an item that has been requested by the user. If the item is not in the cache i.e. if(o1 == null) then it will call a class that generates that object and places that object into the cache. The second time the user makes the same call then they will be handed a cached copy of that object which is aimed to make the whole servlet call faster.
That section of the code works fine coz I have tested that separately. It is the reading in of the arguments that is causing the problem.

Your Apple TV is connected to your wi fi network but cannot connect to the internet. Airplay logo not available on ipad3, iPod touch3g and showing intermittently in iTunes on windows laptop. Switched ISP a few days ago. Entered pass key info on all.

I switched ISP a few days ago and had problems with airplay since. After restarting and reinstalling and updating, re entering pass keys for new wi fi on everything, Apple TV shows: Your Apple TV is connected to your wi fi network but cannot connect to the Internet. Ipad3 and iPod touch 3G have no airplay icon or get one briefly then it disappears again. Same with itunes on windows laptop.
Can anyone help?
Bob

Welcome to the Apple Community.
Intermittent problems are often a result of interference. Interference can be caused by other networks in the neighbourhood or from household electrical items.
You can download and install iStumbler (NetStumbler for windows users) to help you see which channels are used by neighbouring networks so that you can avoid them, but iStumbler will not see household items.
Refer to your router manual for instructions on changing your wifi channel or adjusting your multicast rate.
There are other types of problems that can affect networks, but this is by far the most common, hence worth mentioning first. Networks that have inherent issues can be seen to work differently with different versions of the same software. You might also try moving the Apple TV away from other electrical equipment.

HT201172 Pass key for iPod to pair with Bluetooth in car

How can I find out the pass key to pair my 7th gen iPod to the Bluetooth in my 2011 Infiniti G37?

Thank you. I have tried that and other connotations, but still no joy. Interestingly enough (said tongue in cheek!) I have just tried to pair my iPhone 5 with my Dell Laptop over Bluetooth (simply to see if I can). My laptop recognized the iPhone, but still my phone failed to pair. Is this a built thing designed to annoy me?

Pass Key date from Sender to Receiver Query

Hi,
We have a requirement to pass key date from the sender query to receiver query.
In our sender query we derive the key date based on the calendar month value entered by the user on the variable screen and this is used to determine the hierarchy structure to be used for report.
The user have the option to drill down to detailed query (using RRI) from the context menu option. We would like to use the same key date in the drill down query as the sender query. The drill down query does not have any variable selection.
In RRI settings I can not see the way to pass on the key date.
Any help is appreciated.
Thanks,
Ankit

Hi Suman,
Yes, we do not have variables in the receiver query as we expect the settings in RSBBS to pass the filter values to the receiver query and which is being done consistently.
The problem is that we do not have any option to pass key date. If required we can add a customer exit variable but how will it work if the user does not want to enter the variable values for the drill down report.
Thanks
Ankit

HT204387 What is pass key?

I am trying to Bluetooth my ps3 to my ipad2 and it recognizes the device but then asked me a pass key on my ps3. What would pass key be or what is pass key?

There is nothing in the iPad's BT stack that would make pairing these two devices useful. As is, the iPad can pair with BT audio devices and BT keyboards. To do anything beyond that would require a 3rd party app; such as an app that lets you pass photos or other types of files between an iPad and another device.

TS1569 Where do I find the pass key for the wireless keyboard?

Where do I find my pass key for my new wireless keyboard?

It comes up on the screen of your Mac when going through the pairing process, as shown here:

Pass data from servlet to jsp using sendRedirect

Hi,
I am passing data from servlet to jsp using forward method of request dispatcher but as it doesn't change the url it is creating problems. When ever user refreshes the screen(browser refresh) it's re-loading both servlet and jsp, which i don't want to happen. I want only the jsp to be reloaded.
Can I pass data from servlet to jsp using sendRedirect in this case. I also want to pass some values from servlet to jsp but without using query string. I want to set some attributes and send to jsp just like we do for forward method of request dispatcher.
Is there any way i can send data using attributes(without using query string) using sendRedirect? Please let me know

sendRedirect is meant as a true redirect. meaning
you can use it to redirect to urls not in your
context....with forward you couldn't pass information
to jsps/servlets outside your own context.Actually, you can:
getServletContext().getContext("/other").getRequestDispatcher("/path/to/servlet").forward(request, response)I think the issue here is that the OP would like to have RequestDispatcher.forward() also update the address in the client's browser. That's not possible, AFAIK. By the time the request is forwarded, the browser has already determined the URL of the servlet, and the only I know of way to have the browser change the URL to the forwarded Servlet/JSP is to send a Location: header (i.e. sendRedirect()). Remember that server-side dispatching is transparent to the client. Maybe there's some tricky stuff you can do with JavaScript to change the address in the address bar without reloading the page?

Hi, Having downloaded Printer pro and printing my first letter, I now find that when logging in again I am faced with a Enter Passkey page, excuse the ignorance but where can I find the pass key code ???

Hi,
I have downloaded Printer pro and having already printed a letter last evening, I now find that on returning to the programme this morning I am faced with an Enter Passkey code.
Please excuse the ignorance, but I didn't expect this, how di I find the Pass key code ??????
Anyone's help with issue would be very much appreciated.
Thank you
Robert T.

Thank you so much for helping,
But i really wonder how you did that. did you always switch between design view and preview view, then change the key position for 2px then switch back, to align the four letters? because i imagine that can get really frustrating, if you have a logo consisting of 58 parts instead of 4!:)
Anyway thank you very much for your time and effort!!!!

No parms passed to controlling servlet

I want a page with an inputfield, 2 selectboxes and 1 (or more) submit-buttons. User MUST select a button before 'controlling servlet' is executed. (I mean, no action when 'enter' is used).
These are the 2 scenarios I tried:
Scenario (A)
When i put the <Form ...> tag at the top of my jsp and include inputfields and buttons, I get a 500_error when the cursor is in an inputfield and users presses 'enter'.
It seems that the parameters are not correctly passed to the 'controlling servlet'
However, when I
1) 'click' the Submit-button
or
2) 'click' outside this inputfield and then 'enter' or 'click' the Submit-button
the parms are correctly passed and 'controlling servlet' is correctly executed.
==>
<FORM action="/servlet/com.clipper.servlets.FQController" method=POST>
<td width="150" height="25" colspan="3" bgcolor="#FFFFFF">
     <INPUT size="15" type="text" maxlength="15" tabindex="1" name="agency" value="<%= ((String) session.getValue("sessionid.useragencycode")).trim() %>"></td>
<td width="600" height="25" bgcolor="#99CCFF" colspan="12">
<p align="left"><INPUT type=submit tabindex="5" name="action" value=" List "></p></td>
</FORM>
Scenario (B)
I changed code and do not have the 500_error when in inputfield but no parms are passed anymore.
This is the code
==>
<td width="150" height="25" colspan="3" bgcolor="#FFFFFF">
     <INPUT size="15" type="text" maxlength="15" tabindex="1" name="agency" value="<%= ((String) session.getValue("sessionid.useragencycode")).trim() %>"></td>
<FORM action="/servlet/com.clipper.servlets.FQController" method=POST>
<td width="600" height="25" bgcolor="#99CCFF" colspan="12">
<p align="left"><INPUT type=submit tabindex="5" name="action" value=" List "></p></td></FORM>
What is the correct implementation of this ?

1. your text field or any other form fields have to place between the <form> and </form> tag..
2. I don't know why you didn't get any paramter values, but you can write a function to list all the parameters that were in the request, call the function in the beginning of your control servlet.... Below is a sample...
     public static void listParameterValues(HttpServletRequest request) {
        Enumeration names = request.getParameterNames();
        if(names != null) {
          String name="";
          while(names.hasMoreElements()) {
            name = (String)names.nextElement();
            String[] values = request.getParameterValues(name);
            if(values != null) {
              for(int i=0; i<values.length; i++) {
                System.out.println("listParameterValues(), " + name + "[" + i + "] = " + values);

How to pass parameters to servlet with POST with Business Service OSB

Hi all.
I am newby in OSB. I am trying to send some values through a POST call to a servlet. I know how to call the servlet with Business Service of type "Messaging Service". I send the parameters of type Text.
I have tried several ways, but I don`t find the proper way yo do it. I have tried to insert the param into the body and into the header.
The problem is that I don`t know exactly where to put them, I don`t know if it must be done in the header or in the boy. I neither don`t know if there is a common way to do this.
Please, could you give me a good example of an insert activity to isert a post parameter inside the call?
For example: now I am using this one:
Expression => "accountType=test"
Location => as first child of"
XPATH => empty.
In variable => body.
Where do I have to insert this, in the body or in the outbounds?
I have followed this posts:

Thanks a lot.

Hi,
Please be carefull about passing values such as Strings or number that contains ',' .
using the way described above.
the best way is to pass an ID and then use a select Statement to get the other Values in the target page.

I want to know whether they is any better way to achieve this.
Please help me out!!!

u can get parameters from the processing form using the HttpServletRequest.getParameter(String ..) method. once got into the first servlet on processing if u need to pass them onto the second servlet using the forward mechanism then u store these values into the HttpServletRequest.setAttribute(...) and using the getAttribute() methos can retrieve them in the other...
