Clearing variable from Request object

Hi everyone,
After getting value from request.getParameter("var"), I want to clear this "var" variable from request scope. So that in the next coming statements if i again call the same request.getParameter("var") statement than it must return null
So how to handle this issue of clearing certain variable from request scope or flushing the whole request object

I don't know what you are trying to do but it sounds confused. I would suggest you read the parameter once, at the beginning of the code. Store it in a variable and use that variable as necessary. If you still need help then would you explain what you are trying to achieve here.

Polish characters are not retrived from request object

Hi
I have a problem in passing POLISH character through request object.
I am calling a servlet from a jsp with a hyper link. when the link in jsp is clicked the following code will be executed
response.sendRedirect(response.encodeURL("http://hostname:8080/appName/abc.do?method=getReport&FirstName=Ko�tun&LastName=Pro�ciak"));
this code is passing two POLISH strings First Name & Last Name to the servlet.
In the servlet i am trying to retrieve the values of the parameters "FirstName" & "LastName".
Sring FN=request.getParameter("FirstName");
String LN=request.getParameter("LastName");
The variable FN & LN doesn't show the POLISH character in servlet.
I tried with the below option in JSP
<meta content="text/html; charset=ISO-8859-2" > (or)
<meta content="text/html; charset=UTF-8" >
(or)
<%@ page contentType="text/html;charset=ISO8859_2" %>
(or)
<%@ page contentType="text/html;charset=UTF-8" %>
In Servlet i tried using
request.setCharacterEncoding("ISO-8859-2");
(or)
request.setCharacterEncoding("UTF-8");
Pl help me.
Thanks in advance

Don't do it then. Those characters are not allowed inside a URL and have to be encoded. You know, that %... stuff.

Getting value of parameter from request object

If i submit a form using button element of html form then i dont get name of the button element as Parameter of request object and hence its value.
why and how?
Thanks in advance

what do you mean submit a form with a button? You don't submit a form with a button, you submit it with a submit element. Unless you use Javascript to submit from an onclick handler in the button. In which case, you aren't submitting from the button, but from the script. I'm not sure that buttons are sent in forms. Why would they? If you are using buttons and Javascript, then you could use a hidden field and set it's value to the button's value when it's clicked before submitting the form.

Clearing values from request in decode method

I am using a custom table paginator. In its decode method I have the next code to control whether next link is clicked:
String pLink = (String)requestMap.get("pLink" + clientId);
if ((pLink != null) && (!pLink.equals(""))) {
     if (pLink.equals("next")) {
     } else if (pLink.equals("previous")) {
}But the next sequence produces some problems:
1.     Initial page load.
2.     Click on next link.
3.     Table navigates ok to next page.
4.     Reload page (push F5).
5.     The previous click still remains in the request, so decode method think next link is pressed again.
6.     Application abnormal behaviour arises.
So, I am trying to clear the next_link key from the request, but next code throws an UnsupportedOperationException:
String pLink = (String)requestMap.get("pLink" + clientId);
if ((pLink != null) && (!pLink.equals(""))) {
     if (pLink.equals("next")) {
     } else if (pLink.equals("previous")) {
     requestMap.put("pLink" + clientId, "");
}Do any of you have some ideas?

How to get binding variables from request

We are trying to use html-db to develop an application which need to get values from user request to use in the queries, i.e. we will have pages depend on several binding variables and the value of these variables will be provided by the user through get/post request. Because the request will be initialed by another application so to use a form to collect the values is not an option.
I am a html-db newbie. Does anyone here know how to do that?

you're right in thinking this is a bit of a newbie html db question. it's a pretty straightforward matter to set up a report in html db that runs off of bind variables that can be set from a URL. you can see a pretty simple example on the first page of our "Sample Application" that's available to install into your workspace. try taking a look at that to see what i mean. you can install the Sample Application by clicking the "Review Demonstration Applications" link that's available right after logging into htmldb.oracle.com. that resulting screen lets you create (or re-create) the Sample App in your workspace. once it's installed, take a look at how the report on page 1 calls the first report on page 201. that report on 201 is dependent on a bind variable, :P202_CATEGORY, that's set from the URL. this particular URL is generated from the report on page 1, but it could just as easily have been generated from your other application. when you look at this example, the two key points to pay attention to are the 1) syntax used in the URL to set the bind variable (which is explained in our online help at http://htmldb.oracle.com/i/doc/mvl_fund005.htm#sthref357) and 2)the way in which that bind variable is referenced in the first sql query region on page 201. take a look at those when you get a chance, and let us know if you have further questions.

Reading Null Values From Request Object

For a proof-of-concept, I wrote a mini program that has 2 files. File #1 is main.html. There's a javascript function called addNewRowToThisTable that isn't displayed but it basically allows the user to create as many rows in the table as user desires. When the "Submit" button is clicked the file ReadIt.jsp is called and it's supposed to display on the first and last names of the people who had the checkbox for that row checked. The best way to illustrate the problem I'm having is through an example. Let's say there are 3 rows:
[x] Alan Anderson [Add New Row]
[ ] Bob Brady [Add New Row]
[x] Carl Chadwick [Add New Row]
[Submit]
Let's assume that only rows 1 and 3 are clicked. After the form is submitted the JSP will print...
firstNameArr .length = 3
lastNameArr .length = 3
isSelectedArr.length = 2
firstNameArr[0] = Alan
lastNameArr[0] = Anderson
firstNameArr[1] = Bob
lastNameArr[1] = Brady
Unfortunately firstNameArr[1] and lastNameArr[1] should be "Carl", and "Chadwick" respectively. I know the reason why it's failing is because my program relies on the array index of the "isSelected" field to perfectly match up with the "firstName" and "lastName" fields. It's unreliable because if the checkbox for a row is not checked then it won't show up in the JSP String array isSelectedArr. I'm not really sure how to get around this problem. I have 2 ideas at the beginning of solutions but I'm not sure how to follow through on either and I'm also not sure if either is the proper approach to take. My guesses are...
1) There's some way in JSP to use "getParameterValues('isSelected')" to retrieve the full array of "isSelected" items regardless of whether or not they're checked. That would guarantee that my arrays would match up correctly. Unfortunately, I haven't been able to find this.
2) Maybe I can put in some sort of ID in the "isSelected" field that would relate the checkbox to the rest of the data in the row. The problem with this is that I've got a dynamic # of rows due to my addNewRowToThisTable method.
So the bottom line is that I'm thoroughly stumped. If anyone can offer advice I'd be very grateful.
main.html
<html><head><title></title></head><body>
<form method="get" action="ReadIt.jsp">
<table>
<tr>
     <td><input type="checkbox" name="isSelected" /></td>
     <td><input type="text" name="firstName" /> </td>
     <td><input type="text" name="lastName" /></td>
     <td><input type="button" value="Add New Row" onClick="addNewRowToThisTable(this)" />
</tr>
<tr>
     <td colspan=4><input type="submit" value="submit"></input></td>
</tr>
</table>
</form>
</body></html>
ReadIt.jsp
<%
String[] isSelectedArr = request.getParameterValues("isSelected");
String[] firstNameArr = request.getParameterValues("firstName");
String[] lastNameArr = request.getParameterValues("lastName");
if (firstNameArr != null) System.out.println("firstNameArr .length = " + firstNameArr .length);
if (lastNameArr != null) System.out.println("lastNameArr .length = " + lastNameArr .length);
if (isSelectedArr != null) {
     System.out.println("isSelectedArr.length = " + isSelectedArr.length);
     for (int i=0; i < isSelectedArr.length; i++) {
          System.out.println("firstNameArr["+i+"] = " + firstNameArr);
          System.out.println("lastNameArr["+i+"] = " + firstNameArr[i]);
%>

it's sort of a kludge, but try this:
your javascript function adds new for fields that get submitted to the servlet. name the checkboxes uniquely with a patterm with said function, say isSelected-1, isSelected-2, isSelected-3... now also name the first and last name fields the same way. fname-1, fname-2, fname-3... lname-1,lname-2,lname-3.
when you get to the page that is supposed to match them up, go through all the request parameters looking for those that start with "isSelected-" take the last char (the index), convert it to an int, and then from your request do:
String first = request.getParameter("fname-" + indexThatWasFound);
          String last = request.getParameter("lname-" + indexThatWasFound);in looping over the request for each index recovered from the searching of the request for the isSelected-n values, you will get the matching first and last name.
I TOLD you it was a kludge.

How to read parameters from request object

We want to read parameters from GET request
but whenever we are calling GET_URI_PARAMETER from the REQUEST we don't see any results
url is like
http://coevi116.wdf.sap.corp:8000/sap(bD1lbiZjPTEwMA==)/bc/bsp/sap/z_test_json/jsontest.htm?PARAM=ABC
But reading PARAM is not givng value of ABC
onCreate and onRequest wherever we put the code it is not reading the value
Can anyone please help and share some expert opinion

in jsontest.htm page create a page attribute named "PARAM" with auto check box checked and check in oninitialization, this will carry the value passed to param from url.

How to reteive '+' from request object.

I have a JSP page there I enter A+**** in a field. Then I entered the data it is coming to a servlet and there the value is reading as
req.getParameter(nodeName); where nodename is the field where I enter the data(i.e. A+****). My problem is the '+' sign is replaced by blank.
and in the servlet the value is showing as A ****.
Can any one suggest how I will get the value A+**** intact in Servlet from the JSP page?

XML used as a source to create the jsp has nothing to do with it. The parameters stored in a XML file on the back end once again have nothing to do with this. The reason a sample of the jsp code and how you are reading it in the servlet are needed is there is no other way for anyone to help you unles they come out to where ever you are and trouble shoot it for you. Usaly that is around $250.00 an hour plus all travailing expenses. I doubt anyone would do it for only a one day engagement let alone a single hour. So either pay someone $4000.00 plus travel expense to come out there and fix it for you or post something that folks can help you with (for free and in a very timely manner).
Since, you are on WebSphere and 5.1.1 is not our of support yet you can alway work a problem ticket through them.

Session Variable in any Object

Hi, I've been developing on java, jsp and struts for a while now, and I've got something that I can't resolve:
I have some session variables in struts, such as User, role, etc... I can get the session using request.getSession() and then get them without any trouble. My design uses the MVC pattern, so I also have a Model Object. I also have a database controller class to store my model. The problem is that I wanna retrieve the session variables from the database controller, and there I don't have the request object. I could use a set, or take the parameters I need, put them on a bean and pass that bean as a parameter; but that would be very ugly, and I would have to change almost every class of my application.
Is there a way to have session variables from any object?
Thanks!!!
Leandro

nope... you have to pass the reference in like anything else.

To find number of parameter from request

Freinds,
Is there any way to find out number of parameter submitted from request object. But the constraint will be with out going through loop.
Example
int count = 0;

The only thing that I see that looks funny to me is when you pass the request object into the method using <%=request%>, Im not sure whats going to happen here because that is suppose to print the results. Have you tried simply using <%request%>?

[Solved] The requested object does not exist. (Exception from HRESULT: 0x80010114)

I have a 8 node cluster with Hyper-V, which will be 10 nodes when it's finally done.
Recently I've been try to add nodes and though that went fine, after about a week I could not open the Failover Cluster Manager anymore.
After some checking I found out that the latest added node was giving problems.
VM's on the node still run and function properly, but most Powershell commands result in a "The requested object does not exist. (Exception from HRESULT: 0x80010114)".
I can suspend the node with Suspend-ClusterNode, but draining roles was unsuccesful in one case.
In the other there were no VM's on the node so suspending went fine.
What I did find out was that when I tried to ping the node from another, proper functioning node, it took a while before the pinging started. It felt like the interface had to come back online on the problem node.
After that, I could add the cluster to the Failover Cluster Manager. However, Powershell commands still give a 0x80010114 error or a CIM error for when I use Get-NetAdapter.
A reboot resolves the problem, but only for about a week.
I know there is a topic with the same title already, but the wbemtest en rollup update "answer" is totally unclear to me why I should change something with wbemtest, or why to install updates that to me have nothing to do with this problem.
Before I did the ping test from a functioning node I pinged my DC and another node from the problem node just fine.
No waiting at all.
The cluster has three networks. Management (host only), Live Migration and iSCSI (also a VMSwitch for certain VM's).
I have no idea where to look. Evenviewer doesn't give me anything I can work with that I can find...

Hi,
Are you using the HP servers? It seems is the HP Nic team service was causing the issue, please try to

How to invoke BPM object instance variable from interactive activity?

I have a screenflow with an automatic activity "A" followed by an interactive activity "B". "B" calls a BPM object "X" and uses a JSP presentation to show its attributes. Is there a way to use another BPM object, say type "Y", create an instance variable of that type inside "A", and get its attributes values from the JSP page associated to "B"?

Try this. It assumes you have:
<li> a user named "auto"
<li> a project variable named "customerType"
<li> an instance variable named "orderAmount" that is a decimal
<li> an instance variable named "order" that is a BPM Object that has attributes named "customerName" and "amount"
ps as ProcessService
xmlObject as Fuego.Xml.XMLObject
do
connectTo ps
      using url = Fuego.Server.directoryURL,
      user = "auto",
      password = "auto"
instF as InstanceFilter
create(instF, processService : ps)
addAttributeTo(instF, variable : "customerType", comparator : IS, value : "Gold")
instF.searchScope = SearchScope(participantScope : ParticipantScope.ALL, statusScope : StatusScope.ONLY_INPROCESS)
for each inst in getInstancesByFilter(ps, filter : instF) do
    // here's how to get the value inside a primitive instance variable
    orderAmtObj as Object = getVar(inst, var : "orderAmount")
    // here's how to get the value of attributes inside a complex BPM Object instance variable
    //    - in this case this is an "order" object with two attributes (customerName and amount)
    orderObj as Object = (getVar(inst, var : "order"))
    xmlObject = Fuego.Xml.XMLObject(createXmlTextFor(DynamicXml, object : orderObj, topLevelTag : "xsi"))
    logMessage "The value of the order object's customer name is: " +
           selectString(xmlObject, xpath : "customerName")
    logMessage "The value of the order object's order amount is: " +
           selectNumber(xmlObject, xpath : "amount")
    // here's a rather uninspired way to retrieve who the participant is that was assigned the instance
    logMessage "The participant assigned to this instance is: " + inst.participantId
end
on exit
disconnectFrom ps
endDan
