Handling Multivalue parameter in jsp

Hi! Can anyone please send the piece of Java code through which multiple values can be handled dynamically and set for the report.I am stuck on that. I was done with drop down functionallity for single discrete values but couldn't set multiple default values selected by the user in the list box.
Can anybody help? Thanks in advance.

Hi Cocuz,
Thanks a lot for the help, but this doesn't solve my purpose as my reports are deployed on the BO server and I am calling them through my JSP's from the server dynamically at run time. I am fetching current values set in the report as .getdefaultvalues() method is not working for list box selection. But the major concern is that in current values, it displays only the values set in the selected values box on the BO server. I want to refresh the list dynamically.
Can you plz help in that?
I have resolved the issue of selecting multiple values and setting for the report, but I want dynamic list to be populated in the list box on my parameter UI.....
I am attaching the code I am using....
IReport theReport = (IReport)oInfoObject;
        //Get a List of Parameters
        List parameters = theReport.getReportParameters();
IReportParameter pf = (IReportParameter)parameters.get(i);
ParameterField field = (ParameterField)pf.getParameterField();
System.out.println("List value 00000000:" +field);
Values defaultValues = field.getValues();
Iterator defaultValueIterator = defaultValues.iterator();
while ( defaultValueIterator.hasNext() ){
                                   String[] arrTemp = null;
                                   Value def = (Value)defaultValueIterator.next();
THANKS IN ADVANCE....

How to assign java script variable to a hidden parameter in JSP?

Hi All,
I want to assign the variable in the Jscript to a hidden parameter in JSP page.
<select name="sortingOption" class="sortingOptions" onchange="changeSortOption(this)">
<c:forEach var="sortingOption" items="${sortingOptionList}">
<c:set var="sortingOptionValue" value="${sortingOption}" target="java.lang.String"/>
<c:choose>
<c:when test="${sortingOptionValue == sortingOptionValueFromRequest}">
<option value="${sortingOptionValue}" selected="selected">${sortingOptionValue}</option>
<input type="hidden" name="srchType" value="none"/>
</c:when>
<c:otherwise>
<option value="${sortingOptionValue}">${sortingOptionValue}</option>
</c:otherwise>
</c:choose>
</c:forEach>
</select>
In changeSortOption script,they capture the value selected by the user and then they submit the form.I want to assign that value to a hidden parameter in JSP,can someone tell me how to do that?
I dont have the Jscript code with me right now to post here.

To the point: just by accessing/manipulating the HTML DOM using JS. Learn JS and HTML DOM. There are basic tutorials at w3schools.com. Besides, your code syntax is still invalid. The input hidden elemend doesn't belong in a select element. Learn HTML. There's a basic tutorial at w3schools.com as well.
For future HTML/JS problems please consult the appropriate forums. This has not much to do with JSP. There are ones at webdeveloper.com.

Creating multivalue parameter in SSRS on top of DB2 views

How to create multivalue parameterized report in SSRS for belo scenerio:
Data source is DB2 and we don't need to write whole query as expression while creating dataset.
But if we don't need to write whole query as expression in SSRS, is that possible to create the view in DB2 with same expression query and while calling the view in SSRS, how multivalue report can be generated.

Hi Andy,
Based on my understanding, you want to create a multivalued parameter in your report. When creating the parameter, you don’t want to write a whole query to specify the parameter’s value which is used in the main dataset, right?
In Reporting Services, if we want to create a multivalued parameter, we can create a new dataset to populate the valid values for the parameter. Within the new dataset, we needn’t write a whole query which is used in the main dataset, we can only retrieve
those data which will be used by the parameter. So in your scenario, you can write a simple query to populate the valid values for the multivalued parameter. If you create a view on database side, you can also call the view in SSRS to retrieve the corresponding
data, then specify the values for the parameter with those data.

How to Handle user Session in JSP

Help me,
How to handle user session in JSP.......

Prakash_Pune wrote:
tell me some Debugging tech. so i can overcome from my problem.....Do you use an IDE? Any IDE ships with a decent debugger where in you can just execute the code step by step, explore the current variable values and check what exactly is happening. For example Eclipse or IntelliJ. If you don´t use an IDE, then just place some System.out.println() or Logger.debug() statements at strategic locations printing the variables of relevance so that you can track in logs what exactly is happening.
or tell any other way to find is my page is thread safe or not...Just write correct code and narrow the scope of the variables as much as possible. If you for example assigned the user object to a static variable or as a servlet´s instance variable, then exactly the same user object would be used everywhere in the application. That kind of logical things.

Multivalue parameter values

@partno is defined a multivalue parameter
when I enter a single part number or leave it empty data is properly returned.
when I enter multiple part numbers data is not returned. I have tried: 604-02394, 604-03492 in the parameter prompt.
I have tried entering those parts on separate lines in the parameter prompt:
604-02394
604-03492
my sql query :
and (fpartno in (@Partno) or '' in (@Partno))
I only want to see those two parts in the report.

Hi JimHoopsDSC,
Per my understanding that you create an multiple values parameter "partno" which haven't specify the "Available values" and "Default Values", when you entered single values or leave it empty in the parameter prompt everything
works fine, but when you try to enter multiple value in it, no data will return right?
I have tested on my local environment and can't reproduce the issue, according to the query you have provided that when the fpartno is not blank, data will filter based on the value in the parameter you have entered, when you enter empty all
the data in the table will return.
Please check details information below to have a double check:
I assumed you have blank values in the field "fpartno", please make sure you have check the "Allow Blank value":
Please make sure you have enter the multiple values as below: every values in a single line:
If I have some misunderstanding, please try to provide more details information about your issue and the parameter you have created.

Split Field and MultiValue parameter

I have a multi-value parameter. Options for example are: Zebra, Elephant, and Seal. Then I have a table (actually a sharepoint list) which one field contains other animals in delimited fashion. For example: Elephant;Lion.
What I have set up is a filter (on either the datasource or the tablix) of [Field] IN @parameter which works fine... as the field isn't also multi-valued. I've tried using the Split function, but then it errors trying to evaluate the filter expression.
What I want to do is to return the row if any selected parameter matches any value in the field.
Does that make sense? I'm trying not to get too wordy. Thanks in advance for any responses.

Hi There
You might be able to do this by the help of some custom code so please do the following
Create a custom function in your report which will convert your string to array as you know your fields contain string value you need to convert that in to array first so please go to your report properties
and code and paste this function
Public Shared Function ConvertStringtoArray(sourceString as String) As string()
Dim arrayOfStrings() As String = sourceString.Split(",")
return arrayOfStrings
End Function
Public Shared Function ConvertStringtoArray(sourceString as String) As string()
Dim arrayOfStrings() As String = sourceString.Split(",")
return arrayOfStrings
End Function
Now in you tablix filter please do the expression like this
=instr(join(code.ConvertStringtoArray(Fields!Country.Value),","),join(Parameters!CountryPram.Value,","))
=instr(join(code.ConvertStringtoArray(Fields!Country.Value),","),join(Parameters!CountryPram.Value,","))
Where please change Parameters!CountryPram.Value to your parameter value and please change Fields!Country.Value to your sharepoint list fields values.
I am assuming that you have used multivalued parameter
I am putting some screenshot for your help
If you have any question please let me know
Many thanks

Handling mouse events in JSP

Hi ,
I have to handle mouse events in JSP,means i have to handle the event
of the user i.e, if he press the lest click we have to handle that
event where he pressed it with JSP. Iam finding examples in Applets ,
nut i have to do it in JSP.Can any body help me please? it's very
urgent.
Thanks in advance
BhargavKumar.B

JSP cannot catch mouse events. You need a clientside language for that, such as Javascript. So catch the mouse click event in Javascript, get the desired information from it and send it as request parameters to the server, so that the serverside logic can intercept on it. You can use AJAX for that, if you want to do it asynchronously.

What is the best way to handle input parameter

When writing sub-vi's, what is the best way to handle input parameter range checking? On the front panel I can choose to have numeric values coerced to be within range, but this does not affect constants or controls wired to the vi when used as a sub-vi. I can build range checking into the vi, but this can result in a cluttered looking vi. Do you have any suggestions.

As you discovered, the Range and Coercion properties of controls do not work when used in sub-vis.
Your best option is to go ahead and build your range checking into your sub-vis. If it�s something you will be doing a lot, just make your range checking a sub-vi and drop it where needed. This will keep the clutter to a minimum. You may end up with more than one range checking VI if you need different functionality, but this will still make less clutter and easier re-use.

Using the Abort button to stop your VI is like using a tree to stop your car. It works, but there may be consequences.

Passing parameter between jsp pages

Hi
I'v got the following problem: I have an jsp page that shows result of sql query as a list of 5 items, if there are more items returned - it shows first five, user is able to see more by clicking to a link which shows him the same page with next 5 items etc. The piece of index.jsp file with that link looks like that:
        <html:link action="<%=(String)request.getAttribute("actionMod")%> module=... name=... styleClass=...>and at the end of initSearchAction I have:
req.setAttribute("actionMod","initSearch.do");Action is defined:

        <action path="/initSearch"
                type="...list.InitSearchAction"
                name="productListForm"
                validate="false"
                scope="request"
                unknown="false"
                >
                <forward name="success" path=".search"/>
        </action>      .search is defined as
<definition name=".search" extends=".main">
        <put name="body" value="/list/index.jsp" />
</definition>The problem is when I set a paramter in initSearchAction like that:
req.setAttribute("handle",h);and try to read it next time when initSearchAction action is running, parameter h is null. I need that to pass handle to stateful session bean that holds important information that need to be static during a session. Can anyone tell me how to pass that handle in some other way?

ania

now it works :)
I'm new to this things so I'm not familiar with all those sessions and requests...
thanks a lot

How to handle oas parameter in the URL

Hi,
I am very curious about the oas parameter in the next URL how to form the value:
OA_HTML/OA.jsp?_rc=<..._LAYOUT>&_ri=275&addBreadCrumb=RS&<...Id>=<param_value>&_ti=2094430068&oapc=3&oas=l305LKdSwzg9iJqy8q00ew..
If I use String createURL() or setForwardURL() then I can make some value for oas parameter. My issue is that the by these methods made values are not correct I would like to manage this value by myself. How can I manage this value, put, set, get anywhere?
Thanks in advance,
Cafer

Hey,
Thank you all for your replies. Actually i forgot to say something to you professionals,
In my Pc, already, i have Oracle Web server which listens to 80, thats why for tomcat itlself i set 8084
as port number at the time of installation, since giving 80 failed to run. Without keeping this in mind, i blindly
changed the port 8084 into 80 in server.xml file, stopped and while starting i get " *The port 80 is already in use*"
Is there any way to skip this 8084?
i use tomcat 6, Waiting for your suggession!
Thanks ,
SRI.

Jsf passing parameter between jsp's

Hi
I have my main.jsp and another screen which i call object.jsp
the object.jsp can present an object in multiple ways : add, edit, view
i have 3 buttons in my main.jsp add, edit, view. I want to pass a parameter from main.jsp to object.jsp such that object.jsp will know in what state its being loaded... how do i do this?
Thanks..

session?
as the article says :
To avoid these problems, developers might use session-scoped variables instead. This fixes both of those problems, but adds new ones:
A single user cannot have two windows open simultaneously; session-scoped variables are global to the user. So, for instance, a user could not work with two different search results simultaneously.
Back button support is highly limited, since navigating back can't magically restore the session to its old state.

Passing parameter between JSP

Hi All,
I want to pass a parameter (let us say data from a text box) from one JSP to another on an event (when 'Submit' button is clicked.). Can you please let me know how to go about this? Any sample codes or any other kind of help will be greatly appriciated.
Thanks in advance.

hi,
It's quite easy, just go thru the following code.
one.jsp
<form action="two.jsp" method="post">
<input type="text" name="name"/>
<input type="submit" value="Press"/>
</form>now receive the value in two.jsp and print the same.
two.jsp
<%
String name=request.getParameter("name");
out.print("Your Name -->"+name);
%>Bala

How to pass Parameter to JSP in USerTask

Hi,
I have a process with UserTask(Worklist). How do I pass a parameter to my custom JSP Page. On UserTask Wizard I selected JSP URL option to display the payload
and that is a custom JSP page that reads data from multiple tables based on the parameter passed.
I have created a Workflow process and I am calling a Custom JSP page to show the data. But from my process I just want to pass in a variable as a parameter to
the JSP Page that then displays the data based on the parameter value, but I can't figure out on how to pass the parameter. Any help is appreciated.
Thanks

I redeployed the application and made the parent applicaion as orabpel, but now I am getting the following error. Any help is appreciated. Thanks
