Servlet only gets null values from mobile
OK, i'm doing a project for college which involves inputting data into an application on a mobile device, sending them to a servlet and updating a database. I've got my mobile app working and sending but the servlet is only receiving null values for it. I'll post the code for d servlet and see if anyone can figure out whats wrong. The problem might not even be the servlet so i'll post part of the mobile app as well. The problem could well be when i'm buffering the content on the mobile to a string. Anyway, any help appreciated, thanks.

For sure you would have to do following on your mobile:

sendToServer(url, content);'?' - is a delimiter of GET parameters and '&' - is a delimiter between GET parameters

Getting null values from array
I have set up an array which is supposed to take the values of a recordset. Only problem is when I display them on the page, I get a list of 'null' instead of the data.
I'm trying to list first and last name (fname_ul & lname_ul in DB)
Here's my code:
<% // Here I'm getting the amt of rows returned
int count=1;
while(rs.next()) {
count++;
%>
<%
int k = count;
int i = 0;
String[] fname = new String[k]; // here i'm trying to initialize the string arrays;
String[] lname = new String[k];
while (rs.next()) {
fname[i] = rs.getString("fname_ul"); // here i'm trying to put data into the array;
lname[i] = rs.getString("lname_ul");
i++;
%>
<table>
<% for (i=0; i < k; i++) { %> // and finally here i'm trying to display the array;
<tr>
<td><%=fname%></td>
<td><%=lname[i]%></td>
<td><%=i%></td> // just something to make sure the rows are counting.
</tr>
<% } %>
</table>
my result is like this:
null null 0
null null 1
null null 18 // this is correct in that there are 19 rows in the resultset.
So, why isn't the data from the recordset going into the array??? Thanks for any help out there. Oh, those comments up there, they're not in the actual code, just to explain here.I have set up an array which is supposed to take the
values of a recordset. Only problem is when I display

%>Well, in the first while-loop, you already loop through all the result set, so in the second while-loop, all you get is a null value.
Also, the way you put the data into the array is not right. I didn't see any array indices. Instead of using arrays, you can consider using Vector, so you don't need to know the number of rows in advance. -
Getting null values from nodes using DOMParser
Hi
I'm having problems retrieving the values from an XML doc.
I'm using the DOMParser, but instead of retrieving the values
from the nodes, I just get null.
Code fragment :
DOMParser parser = new DOMParser();
parser.parse(url);
XMLDocument doc = parser.getDocument();
NodeList nl = doc.getElementsByTagName("*");
Node n;
iNode = nl.getLength();
for (int i=0; i<iNode; i++)
n = nl.item(i);
String szNodeName = n.getNodeName();
System.out.print(szNodeName+ " (" );
System.out.print(n.getNodeValue()+")");
System.out.println();
The result is
course (null)
Name (null)
All the node names are correct, but the node values are NOT
displayed.
Any idea ?
Rodrigo
nullAccording to the DOM Level 1 spec, the "value" of an ELEMENT node
is null and the getNodeValue() method will always return null for
an ELEMENT type node. You have to get the TEXT children of an
element and then use the getNodeValue() method in the text nodes.

Midlet gets null values from servlet
hey,
based on one of the source code examples on the java.sun.com website i made a midlet/servlet application. the midlet is sending a product id to the servlet, the servlet queries the database and shows the productinformation, the midlet reads the servlet output and displays it on his midlet form
when i invoke the servlet in my browser: http://localhost:8080/Magazijn/query?product=1 then everything works fine (i see: Product Name : Deur). when the midlet is invoking the servlet i see Product Name : null
after hours of searching the only thing i could come up with is that the servlet isn't passing the string retrieved from the resultset to the midlet
the strange thing is that when i papss a normal string, for instance:
String test = "test";
out.println(test);
that he shows this correct both in my browser and midlet
when i do this:
prodName = resutl.getString("name");
out.println(prodName);
i see "Deur" in my browser, but i see "null" in my midlet
anyone can help me?

leeHi,
first for some efficeincy, in your place your connection to the database in the init() method so you can have on instance of the connection.
in your midlet place the ui initialization in its constructor
ok, Why dont you try the query in the url
i.e http://localhost:8080/Magazijn/query=";
then as you input the product id without setting requests
c = (HttpConnection)Connector.open(url+productid);
i think it will work properly
tell me what happens with you -
Getting null values from resources in jar
My application uses a lot of icons, i have bundled these icons in a jar file which is there in the classpath.
I am using these Icons from my class statically; i mean to say all the icons are initialized as final static.
and when i run the application it give me null pointer exception.
Same thing if i remove static i am not getting the nullpointer exception.
Nas.Then don't use static then! Why you have to make these fields static?

How to get argument value from portal desktop URL
hi,guys
I have a question ,it is how to get argument value.see:
in one portal desktop,I have a hyperlink like this
http://localhost:7001/TestPortal/appmanager/testPortal/testDST?eventId=1
after click,then will be switch another desktop "testDST"
I tried to get value from request,but failure.
@RequestMapping
public String listTestList(RenderRequest request, RenderResponse response,ModelMap model) {
//HttpServletRequest httpRequest = (HttpServletRequest) ; //request.getAttribute("javax.portlet.portletc.httpServletRequest");
//log.debug("httprequest eventId>>>" + httpRequest.getParameter("eventId"));
log.debug("render request eventId>>>" + request.getParameter("eventId"));
I can't get this value from request,also tried httpServeltRequest,but httpServletRequest can't get,it is null;
so ,how to get this value,thank you very much.
regards
arisHello,
It is true for JSR168 portlets that you can't just arbitrarily set parameters on a URL and get access to them inside your portlet- you must use the appropriate APIs on the PortletURL class to set parameters that you can retrieve. This is the only portable (standards-compliant) way to implement the functionality you want.
However, for your particular use-case, you can get the URL parameters from the (non-JSR168) HttpServletRequest object. The only reason you are getting a null object for that is because the attribute name is wrong. This should work:
HttpServletRequest httpRequest = (HttpServletRequest)(request.getAttribute("javax.servlet.request"));
String eventId = httpRequest.getParameter("eventId");

How to get Array values from context
In my jsp page, I have a group of checkboxes, named "checkbox" and each of them has a different value.
<form>
<input type=checkbox name=checkbox value=1>
<input type=checkbox name=checkbox value=2>
After I submit the form, I need to get the checkbox's values from next page's control file, which is a Java file. In the Java file, I use "com.sap.mbs.core.api.Context" class,
String cbString = (String)context.getNodeList().get("checkbox");
but I can only get the value of the first checkbox.
I have tried context.getValue("checkbox", 0), context.getValue("checkbox", 1), context.getValue("checkbox", 2), but all I got is "null".
I beleive the context has the value of the checkbox array. But how to get them out? Thanks a lot!Jo:

Getting the Values from a Tiled View
Hi,
I have a TiledView and I have checkbox in the tiled view. I am trying
to get the values of the checked boxes.
I have coded like this.
Object[] links = getRSystemLinks().getCbSystemUrl().getValues();
if I see the links.length i get only one. In html If I see the code
it appends the TileIndex in brackets. If I replace the TileIndex with
0 in all the fields in endCbSystemUrl method I get the correct values.
In the TiledView beginDisplay() method my code is like this.
if (getPrimaryModel() == null) throw new ModelControlException
("Primary model is null");
super.beginDisplay();
resetTileIndex();
pgCustomizeLinksViewBean parentBean = (pgCustomizeLinksViewBean)
getParent();
((DatasetModel) getDefaultModel()).setSize
(parentBean.SystemChoicesValue.size());
Any Suggestions on this.
Thanks
NamburiNamburi--
Remember, the getValues() method does not return the values from a column in
a TiledView. It is strictly for use by fields that can have multiple
values, like multi-select list boxes.
DO NOT remove the indexing feature from the field names, especially in the
case of checkboxes, because checkboxes aren't submitted back to the server
unless they are checked. By overriding the automatic checkbox tracking
feature JATO provides, you won't be able to tell which checkboxes were
actually checked by row--you'll simply get back a list the same size as the
number of checkboxes that were checked, without any placeholders for the
ones that weren't checked.
Instead, on submit, you simply need to move through the tiledView and check
the value of checkbox on each row:
tiledView.beforeFirst();
while (tiledView.next())
if (getDisplayFieldBooleanValue("myCheckBox"))
You can use the same construct to build up an array or list:
List checkedList=new LinkedList();
tiledView.beforeFirst();
while (tiledView.next())
if (getDisplayFieldBooleanValue("myCheckBox"))
checkedList.add(new Boolean(true))
else
checkedList.add(new Boolean(false))

NullPointerException - Cannot get the value from variable f_cashGiven
In SubCheckout.java (a POS), what I want is when Payment button (f_cashPayment) is pressed, the action "Cash" is performed, get the value from Cash Given (f_cashGiven), do the subtraction and post the value as Cash Return (f_cashReturn). The code is filled in actionPerformed. But I cannot get the value by using f_cashGiven.getValue() from VNumber class. It returns NULL. This should be quite straight forward, but I do not know what is wrong. Please help!

How to get each value from a parameter passed like this '(25,23,35,1)'

One of the parameter passed to the function is
FUNCTION f_main_facility(pi_flag_codes VARCHAR2) return gc_result_set AS
pi_flag_codes will be passed a value in this way '(25,23,35,1)'
How to get each value from the string
like 25 first time
23 second time
35 third time
1 fourth time

and to_date('01-JAN-10', 'DD-MON-YY') between t2.att_start_date AND t2.att_end_date) q1,
(SELECT t2.org_id, t4.description

I am using oracle 10g.
In the process of getting each number from the parm '(25,23,35,1)' , I also need the position of the number
say 25 is at 1 position.
23 is at 2
35 is at 3
1 is at 4.
the reason I need that is when I build seperate select for each value, I need to add the query number at the end of the select query.
Please see the code I wrote for it, But the select query is having error:-
BEGIN
IF(pi_flag_codes IS NOT NULL) THEN
SELECT length(V_CNT) - length(replace(V_CNT,',','')) FROM+ ----> the compiler gives an error for this select query : PLS-00428:

Pls help me with fetching each value to build the where cond of the select query along with the query number.
Thank You. -
How to get the value from the checkbox
Hi All,
Good Evening,
i want to get the value from the check box.
for this i wrote like this
OAMessageCheckBoxBean cbb=(OAMessageCheckBoxBean)webBEan.findChildRecurssive("item240")
String val=cbb.getvalue(pageContext).toString();
val getting the value only when checkbox is checked.
suppose check box is not checked that time i got NULL POINTER exceptionn.
so
i tried the following way alsoo
string val=pageContext.getParameter("item240");
here val return 'on' only when checkbox is checked.
otherwise NULL value returnss.
but i want to get the value is 'Y' when i am checked the checkbox
otherwise returns NULL valuee.
already i set the checkbox properties alsoo
Checked :Y
unchecked:N
pls tell meHi,
use
try
OAMessageCheckBoxBean cbb=(OAMessageCheckBoxBean)webBEan.findChildRecurssive("item240")
String test = cbb.getvalue(pageContext).toString();
catch(Exception e)
String test = "";
this way you can handle null pointer exception.
Thanks,

Prevent null values from displaying in answers OBIEE 11g
Is there any possibilities in OBIEE to Prevent null values from displaying in answers
For example, If i have two records in table
TV cost=NULL(having agg rule sum in BMM layer)
RADIO cost=10(having agg rule sum in BMM layer)
in answers i get two records
TV NULL
RADIO 10
but i want to get one, only with not null costJust want to clarify your question,You want to eliminate the NULL values from the report am i right? If that is the case then put the filter COST <> NULL.
Do let me know the updates?
Thanks, -
Error while selecting NULL value from Popup Key LOV(numeric or value error)
Hi,
I have a item P1_DEPTNO with following properties.
P1_DEPTNO - Popup Key LOV (Displays description, returns key value)
LOV - P1_DEPT_LOV
select deptname d, deptno r from deptP1_DEPTNO item properties
List of Values
Named LOV - P1_DEPT_LOV
Display Null - Yes // changed to Yes, so that it can accept NULL values.
Null display value - NULL
Null return value - (blank)PL\SQL Process -
declare
v1 number;
begin
if :P1_DEPTNO is null OR :P1_DEPTNO = '' then
v1 := 0;
else
v1 := :P1_DEPTNO;
end if;
// rest of the PL\SQL process
end;Now, when I run the page and select NULL value from Popup LOV and submit, I get the following error.
ORA-06502: PL/SQL: numeric or value error: character to number conversion error.When, I select any other value other than NULL, then it's working perfectly fine.
Only in case of NULL value, I am getting this error.
ANY idea, why this error is coming??
Thanks,
DeepakHi Varad,
I did the following change
Null display value - (blank) // by default it is displaying '%' in the select this
Null return value - -1
but when I select % (null value) from the popup list, it displays the return value -1 in the text field.
My question is why it is displaying the return value -1 in the text field...*It should display the display value in the text field (i.e blank in this case)*
then, I did the following change
Null display value - (blank) // by default it is displaying '%' in the select this
Null return value - // a single space, so that when I select %(null value) from the list, it should display blank in the text field...
then I did the following change in the PL\SQL process.
PL\SQL process
declare
v1 number;
begin
if :P1_DEPTNO = ' ' then // -- checking the value of single space ' ' when we select %(null) in the popup list, BUT even I select %(null), control is not coming here.
v1 := 0;
else
v1 := :P1_DEPTNO;
end if;
// rest of the PL\SQL process
end;Thanks,
Deepak
