Newbie - How to retrieve a "Boolean" value in a jsp via jsf ?
Is it possible to retrieve a Boolean value from a BBean from, from let's say a 'rendered' tag ?
class BBean
Boolean secure;
public Boolean getSecure() {...}
From the jsf:
<h:outputText value="#{somebean.whatever}" rendered="#{BBean.? == false}" />
How do I use the Boolean object in an expression like the one above ?
Note: I've simplified the example above, but I cannot use a primitive boolean for this, the objects I use
are generated with "Boolean"s and I have no control.
Thanks in advance !
Mark
You should just use boolean instead of Boolean;
class BBean
boolean secure;
public boolean getSecure() {...}
<h:outputText value="#{somebean.whatever}" rendered="#{bBean.secure == false}" />

How to retrieve dynamic filter value submitted from control query to .....
How to retrieve dynamic filter value submitted from control query to broadcast query.....
I'm trying to change the hierarchy version determined by a userexit variable in the broadcast query.
The Hierarchy Version should be dependent on the input filter delivered by the bursting query.
But how do I catch the dynamic filter value which has been submitted by the bursting query,
with other words: where does the bursting query store it's out put while sequentially starting the broadcast query value by value?
BTW: the filter value from the bursting query appears under "dynamic filter values" in the information of the broadcast query...
Any thoughts are welcome!

How to retrieve the parameter names from a JSP page ? Urgent Please
Hello,
Can anybody tell me how to retrieve the parameter names from the JSP
page. (without using getParameterNames() method.)
The problem with the getParameterNames() method is I get the Jumbled output.
I need it very badly
With regards
Ananth R
email:[email protected]
[email protected]Dear duffymo,
My primary intention is to convert the JSP form information into a XML file.
If I do not get the Parameter names in the correct order how can I maintain
tag order in XML file.
For ex: (JSP PAGE VIEW)
Name--
FirstName
MiddleName
LastName
Address--
Street1
Street2
City
Country
&so on
(XML File to be generated)
<Name>
<FirstName>Value</FirstName>
</Name>
<Address>
<street1>value</street1>
</Address>
& so on
If I use getParameterNames() to get all the parameter names(Which form the tag names in the XML file ) the Enumeration object it returns will not be in the same order as the text fields in JSP.From this I can not construct a meaningful XML file.
order means: Order of entry on the page, from top to bottom
That's it

How to retrieving attributes old values from a OBJECT_CHANGED event
Hi,
I have installed Sun ONE Directory Server 5.2. I have registared Event Listener which implements both name space change and object change interfaces. After chaning some attribute value, i am able to get the new values of attributes using getNewBinging method. But when i call getOldBinding to get attributes, it is returning null. Can any one help me how to get the old values. This is very much urgent and we are trying to write custom connectors to synchronize the data in Sun ONE directory server with other directory servers like Oracle Internet Directory.
I am new to Java and JNDI.
It would be great help if any one can light me in this regard. Thanks in advance.
Thanks & Regards
SreedharI have been also working for the same issue. getOldBinding() does not return old attributes in case of ObjectChanged event. So far I did not find any solution. Does anyone know any solution?

Passing values to included jsp via bean
Hi people
I've got a jsp fragment which is used by many jsp's. It outputs a dynamic menu. It gets its data from a bean, say MenuBean. The jsp which "includes" menu.jsp does a jsp:usebean then jsp:setproperty's on MenuBean. When I run the project nothing comes up in the menu (It works if I hardcode the values in MenuBean).
Under debug I can see that after the first jsp:usebean an instance (say #9360) is created with the properties set correctly. But when menu.jsp runs, it looks like a new instance of MenuBean (say #110636) is created with the properties blank.
in home.jsp:
<jsp:useBean id="menubean" class="web.MenuBean" scope="session"/>
<jsp:setProperty name="menubean" property="login"
value="${userBean.login}"/>
<jsp:setProperty name="menubean" property="topLevel" value="Home"/>
<jsp:include page="/WEB-INF/jspf/menu.jsp" />
in menu.jsp:
<jsp:useBean id="menubean" class="web.MenuBean" scope="session"/>
I've tried changing the scope to request or application, but it's always the same result. A new instance of MenuBean is created when menu.jsp runs. What I need is a single instance of MenuBean running throughout the session and accessible by every jsp that's called up. How can I do/achieve this?
I'd appreciate any help on this matter.
Thanks.Hi Ram - thanks for your reply.
I have made it work, but I'm not sure which of the changes I made is the one that fixed it. I believe it is because I didn't implement serializable in my MenuBean. By doing so it now works!!
thankyou & bye -
How to retrieve the max value from a cursor in procedure
Hi,
In a procedure, I defined a cursor:
cursor c_emp is select empno, ename, salary from emp where ename like 'J%';
but in the body part, I need to retrieve the max(salary) from the cursor.
could you please tell me how I can get the max value from the cursor in the procedure.
Thanks,
PaulHere is one sample but you should just get the max directly. Using bulk processing should be a last resort.
DECLARE
CURSOR c1 IS (SELECT * FROM emp where sal is not null);
TYPE typ_tbl IS TABLE OF c1%rowtype;
v typ_tbl;
max_sal number;
BEGIN
OPEN c1;
max_sal := -9999999999999;
LOOP --Loop added
FETCH c1 BULK COLLECT INTO v LIMIT 3; -- process 3 records at a time
-- process the records
DBMS_OUTPUT.PUT_LINE('Processing ' || v.COUNT || ' records.');
FOR i IN v.first..v.last LOOP
if v(i).sal > max_sal then
max_sal := v(i).sal;
end if;
DBMS_OUTPUT.PUT_LINE(v(i).empno);
END LOOP;
EXIT WHEN c1%NOTFOUND;
END LOOP;
DBMS_OUTPUT.PUT_LINE('Max salary was: ' || max_sal);

How do i retrieve the multivalue Role values and not just a single entry?
Thanks,
KevinI see what i missed with the doube slash, i thought you had a typo and assumed i used it. If i use the following:
//Retrieve Requester Roles
Object requesterRolesXMLElem = getVariableData("inputVariable", "payload","/ns3:process/ns4:RequesterDetails//ns4:Role");
System.out.println("Requester Roles Type[" + requesterRolesXMLElem.getClass() + "]");
int requesterRolesCount = ((oracle.xml.parser.v2.XMLElement)requesterRolesXMLElem).getAttributes().getLength();
System.out.println("Requester Roles Length[" + requesterRolesCount + "]");
String requesterRole = ((oracle.xml.parser.v2.XMLElement)requesterRolesXMLElem).getText();
System.out.println("Requester Roles[" + requesterRole + "]");
I get the following output:
Requester Roles Type[class oracle.xml.parser.v2.XMLElement]
Requester Roles Length[0]
Requester Roles[SYSTEM ADMINISTRATORS]
I am not seeing how to loop through each if the type is class oracle.xml.parser.v2.XMLElement
