NULL Value in OO Context
Hi ,
I want to set NULL Value in OO Context.
I cannot use clear with NuLL, SInce it is not allowed in OO Context.
Do anybody know Class xyz => NULL_Constant ?
Eg cl_abap_char_utilities=>NEWLINE

That's because the initial value of a character field is SPACE. In the same way, the initial value of an integer field is 0. Again, looking at the ABAP help:
Type Initial Value
b 0
c " " for every position
d "00000000"
f 0
i 0
n "0" for every position.
p 0
string empty string of length 0
s 0
t "000000"
x hexadecimal 0
xstring empty string of length 0.

Hi
I am working on Proxy to SOAP Scenario, I receive null value at the first instance when I display the Queue, and values after the null, and the values are coming from the different nodes, and mapping needs to be done at the different level too.
Example I receive the state vale as
1. null
2.CA
3.NV
in order to avoid the null value while mapping what is the function to use it, I used Remove context but still I receive the null value at the begining
Thanks
PRHi PR,
In my case, because of this change in 7.1 a mapping which is working in 7.0 was resulting in wrong results in 7.1
I doubt this change was done by SAP in 7.1 for ease of use in UDF.
However, in your scenario try placing a remove contexts-split by value immediately after the condition it suppress the null.
Else provide me your condition in MM I will replicate and help you.
Also, try changing the context to a higher level
Venkat.

Using Convert to handle NULL values for empty Strings ""
After having had the problem with null values not being returned as nulls and reading some suggestion solution I added a converter to my application.
<converter>
<converter-id>NullStringConverter</converter-id>
<converter-for-class>java.lang.String</converter-for-class>
<converter-class>com.j2anywhere.addressbookserver.web.NullStringConverter</converter-class>
</converter>
...I then implemented it as follows:
public String getAsString(FacesContext context, UIComponent component, Object object)
System.out.println("Converting to String : "+object);
if (object == null)
System.out.println("READING null");
return "NULL";
else
if (((String)object).equals(""))
System.out.println("READING null (Second Check)");
return null;
else
return object.toString();
public Object getAsObject(FacesContext context, UIComponent component, String value)
System.out.println("Converting to Object: "+value+"-"+value.trim().length());
if (value.trim().length()==0 || value.equals("NULL"))
System.out.println("WRITING null");
return null;
else
return value.toUpperCase();
...I can see that it is converting my values, however the object to which the inputText fields are bound are still set to empty strings ""
<h:inputText size="50" value="#{addressBookController.contactDetails.information}" converter="NullStringConverter"/>Also when reading the object values any nulls are already converted to empty strings before ariving at the converter. It seems that there is a default converter handling string values.
How can I resolve this problem as set nulls when the input value is an empty string other then checking every string in my class individually. I would really hate to pollute my object model with empty string tests.
Thanks in advance
Edited by: j2anywhere.com on Oct 19, 2008 9:06 AMI changed my converter as suggested :
public Object getAsObject(FacesContext context, UIComponent component, String value)
if (value == null || value.trim().length() == 0)
if (component instanceof EditableValueHolder)
System.out.println("SUBMITTED VALUE SET TO NULL");
((EditableValueHolder) component).setSubmittedValue(null);
else
System.out.println("COMPONENT :"+component.getClass().getName());
System.out.println("Converting to Object: " + value + "< to " + null);
return null;
System.out.println("Converting to Object: " + value + "< to " + value);
return value;
}which produces the following output :
SUBMITTED VALUE SET TO NULL
Converting to Object: < to null
Info : The INFO line however comes from my controller object where I print out the set value :
package com.simple;
import java.util.ArrayList;
import java.util.List;
public class Controller
private String information;
/** Creates a new instance of Controller */
public Controller()
System.out.println("Createing Controller");
information = "Constructed";
public String process()
System.out.println("Info : "+getInformation());
return "processed";
public String reset()
setInformation("Re-Constructed");
System.out.println("Info : "+getInformation());
return "processed";
public String setNull()
setInformation(null);
System.out.println("Info : "+getInformation());
return "processed";
public String getInformation()
return information;
public void setInformation(String information)
this.information = information;
}I also changes my JSP / JSF page a little. Here is the updated version

How to post null values from h:inputText?
Hello,
I have a form made of h:inputText fields that map to an entity class as the backing bean. Whenever I post the form from a web page, all the fields that I did not fill out and that are mapped to String fields in the entity class are set to "" (empty string) instead of null.
However, I would like to post null values to my entity, because that would indicate that the user did not fill out the field. In other contexts (outside of the web app) it is possible to set the fields to empty strings, but from the web app it should always be null. How can I get JSF to do this correctly?
Also, when reading entitys with null values from the database, these are converted to empty h:inputText fields, so this direction works as expected.
UlrichI haven't seen a solution for this as far.
This is how I do it:
public void action() {
if (isEmpty(inputValue)) {
// do your thing
} else {
// do your thing
public static boolean isEmpty(Object value) {
if (value == null) {
return true;
if (value instanceof String && ((String) value).trim().length() == 0) {
return true;
if (value instanceof Collection && ((Collection) value).size() == 0) {
return true;
// And go so on .. make it an utility method.
return false;

N:1 mapping problem with incoming NULL value
Dear experts,
i have a problem mapping an incoming Idoc to XML file. Here's the situation:
1) Structure of inbound Idoc
ZTST00
ZTST01 Structure: FIELDNAME, FIELDVALUE. Values: FIELDNAME = "Z1", FIELDVALUE = "4";
ZTST01 Structure: FIELDNAME, FIELDVALUE. Values: FIELDNAME = "Z2", FIELDVALUE = null;
ZTST01 Structure: FIELDNAME, FIELDVALUE, Values: FIELDNAME = "ZABC", FIELDVALUE = "5";
ZTST01 Structure: FIELDNAME, FIELDVALUE. Values: FIELDNAME = "Z4", FIELDVALUE = "6";
ZTST02
2) Resulting XML:
LINEHEADER (1 line)
LINEDETAIL (1 line, Structure: VALUE)
LINEFOOTER (1 line)
3) I need to map ZTST01-FIELDVALUE to LINEDETAIL-VALUE, but only if the FIELDNAME equals "ZABC".
In my message mapping, i put an IF FIELDNAME = 'ZABC' THEN FIELDVALUE->VALUE, on context ZTST00. But because of the null value in line 2 of the Idoc, the value that is returned to the XML is "6", as the null value is disregarded and not in the queue of FIELDVALUE.
How can I put the correct value ("5") to LINEDETAIL-VALUE?
Regards
WilliamHi William,
Simply go back to the default context ZTST01 (for both: FIELDNAME and FIELDVALUE fields) and it should be fine.
Hope this helps,

Issue with Results from Another Query (Error on Null value)
Hi All,
We have a WebI report using "Result from Another Query" option of BO XI R3.1. The report was running fine till recently the dimension object using result from another query had a null value. Report suddenly throwed error as the query filters are invalid.
Is there a way to make this filter optional if no data/null value is there ? Because we need those null values in report as well.
Thank you for your time.
Thanks & Regards
LNHi Vivek,
It was not directly solved but I applied alternate logic to over come the issue.
Here's what I did to overcome:
I used a sub query in place of the whole result from another query.
For Ex:
Dim1 inlist result from another query1
I made it as
Dim1 inlist (Dim0)
where Conditions.
Here Dim0 is the object which we use for Result from another query and Conditions will be the necessary filter conditions to arrive proper Dim0. Make sure proper context is formed for the sub query.
Even though it resolved my problem, It introduces an new issue. It causes increase in query run time when huge set of data is returned from sub query.
Please let me know if i haven't explained clearly.
Hi Aris_BO,
Sorry for not responding earlier. The logic would probably make more queries null & not null. Thats why I was not advised to use it.
Thanks

Component binding return null value
I'm migrating a JSF 1.2 application to JSF 2.1, specificly I'm currently using mojorra 2.1.24.
The application consists of request scoped beans, and in order to pass data between requests, it embeds the data inside UI components.
The following behaviour works well with JSF 1.2, but not with JSF 2.1.
The application has the following configuration:
<context-param>
<param-name>javax.faces.STATE_SAVING_METHOD</param-name>
<param-value>client</param-value>
</context-param>
The page contains the following snippet:
<h:form prependId="false">
<h:inputHidden binding="#{bean.inputHidden}" />
<h:panelGroup rendered="#{bean.rendered}">
<h:commandLink value="onAction" action="#{bean.onAction}" />
</h:panelGroup>
</h:form>
The bean is the following:
@ManagedBean
@RequestScoped
public class Bean {
private UIInput inputHidden;
private AItem item;
public setInputHidden(UIInput inputHidden){
this.inputHidden = inputHidden;
if(item != null){ this.inputHidden.setValue(item); }
public AItem getItem(){
return (AItem) getInputHidden().getValue();
// other getter/setter
public String onNavToPage(AItem item){ this.item = item; return "page"; }
public String onAction(){ //... do something return ""; }
public boolean isRendered(){ return getProcessItem() != null; }
The steps are the following:
to navigate to page page the method bean.onNavToPage is invoked from within another page;
upon page rendering the bean.item is set as bean.inputHidden value;
after the page is diplayed, the command link is pressed.
At this point no command link is invoked, because the bean.inputHidden.getValue() returns null, and the command link is not processed.
I noticed that the inputHidden parameter passed to the setInputHidden method during restore view phase has, inputHidden.getValue() == null, no value has been saved previously in the view.
I would guess that something has changed in the component state management, but debugging the JSF code I didn't find what.
Debugging JSF code I found that the component state has been masked before the state has been saved in the view, so the ComponentStateHelper.saveState saves the deltaMap and not the defaultMap, where all the state has been put.
public Object saveState(FacesContext context) {
if (context == null) {
throw new NullPointerException();
if(component.initialStateMarked()) {
return saveMap(context, deltaMap);
else {
return saveMap(context, defaultMap);
is this a bug?
If not, how can I restore JSF 1.2 behaviuor and save the defaultMap?

Hide Null Value in Drill Down KPI
Dear Sir,
I have Problem : i want to Hide the Null Value in SSM KPI. This is the link picture ( http://tinypic.com/r/aak9r6/5 ).
Thanks for your answer.Por,
Can't remember if you are on 7.5 or 10. On 7.5 , go to Administrator interface Scorecards > Set Scorecard Defaults > select the Context from the picklist and in the middle of the page KPIs - Set Missing or Null Data. The default is Display KPI, hide indicators, but you can also choose Hide KPI.
In SSM 10 this same function is under Context Management > Scorecard Defaults. Contexts are listed in box instead of picklist.

Geting null values from request
hi!
i m producing this code through out.println() method in my page and then using java script
i am submiting this page to another page
<td width="56%"><textarea name="question_no_1"></textarea></td>
<input name="question_no_1_radio1" type="radio" value="radio"></td>
<td width="59%"> <textarea name="question_no_1_ans1"></textarea></td>
<input type="radio" name="question_no_1_radio2" value="radio"></td>
<td><textarea name="question_no_1_ans2"></textarea></td>
<input type="radio" name="question_no_1_radio3" value="radio"></td>
<td><textarea name="question_no_1_ans3"></textarea></td>
<input name="question_no_1_radio4" type="radio" value="radio"></td>
<td><textarea name="question_no_1_ans4"></textarea></td>
but when i submit it to the other page and try to retrieve value of parameter "question_no_1"
through the bellow statement it shows a null value but i have given a value previously by
typing a question in it
System.out.println("the Body Of The First Question Is "+request.getParameter("question_no_1"));
can anybody help me what is going on here.
also if i try to normaly submit first page (ie <form="form1" method="post" action="other_jsp_page.jsp"> ) then the statement in the next page gives me the correct value but
i have to submit the first paper through java script.
if u want to see full detail of my code then go to the following link
http://forum.java.sun.com/thread.jsp?thread=309254&forum=45&message=1237097
thanx in advanceOK, your problem is that you are not submmiting the values to the other page. When you do the
--> document.forms[0].submit();
in JavaScript, the form has to action defined
--> <form name="form1" method="" action="">
So, the page does nothing. The line following the submit just changes the location of the page, IT DOES NOT POST the values.
One solutions is the following:
1.- define an action for your form:
<form name="form1" method="POST" action="'save_paper.jsp">
2.- Then create a JavaScript function that validates the fields and simply return "true" if the form is correct, and false if there is a problem (just a little modification of the one you have).
3.- Then modify your submit button:
Instead of:
<input type="button" name="Save" value="Save" onClick="validateField()">
Try:
<input type="SUBMIT" value="Save" onclick="validateField();"> -
Not to display the null values from data base
Hiiii.
In a jsp file i have ten check boxes.The jsp file is mapped to a servlet file for parameter requesting and to
store it in DB.
The unchecked box values has null values.All the values are store in a Mysql DB table.
Again i have to display it in a jsp page from table.
The problem am facing was,how can i display only the values in a row.it must not display the null values and the crresponding column name.
Or any other way is their like below
How i can retrieve only the selected check boxes from tht jsp file.and store in backend.
Thanks in Advance
regards,
satheesh kannanHere is a rough example that may give you some ideas:
On the JSP page:
<%if(myData.getFirstName()!=null){%>
Your First Name'
<input type="text" name="firstName" value="<%=myData.getFirstName()%>">
<%}%>
In the servlet:
String firstName= request.getParameter("firstName");
if(firstName!=null){
//write it to the database

JDBC MS Access--- cannot extract entry with null value with data type Meta
I'm trying to extract a data entry with null value by using JDBC. The database is MS Access.
The question is how to extract null entry with data type memo? The following code works when the label has data type Text, but it throws sqlException when the data type is memo.
Any advice will be appreciated! thanks!
Following are the table description and JDBC code:
test table has the following attributes:
Field name Data Type
name Text
label Memo
table contents:
name label
me null
you gates
Code:
String query = "SELECT name, label FROM test where name like 'me' ";
ResultSet rs = stmt.executeQuery(query);
while (rs.next())
String name = rs.getString("name");
rs.getString("val");
String label = rs.getString("label");
System.out.println("\t"+name+"\t"+label);
catch (SQLException ex)
System.out.println(ex.getSQLState());
System.out.println(ex.getErrorCode());
System.out.println("in sqlexception");
output:
C:\Temp\SEFormExtractor>java DBTest
yet SELECT name, label FROM test
null
0
in sqlexceptionThe question is how to extract null entry with data type memo?Okay, what you need to do is this:
if (rs.getString("val") == null)
// do something
}This way, when it's a null value, you can check it first, and then handle it how you want, rather than getting an exception. -
Index (or not) for excluding NULL values in a query
Hello,
I have table that can become very large. The table has a varchar2 column (let's call it TEXT) that can contain NULL values. I want to process only the records that have a value (NOT NULL). Also, the table is continuously expanded with newly inserted records. The inserts should suffer as little performance loss as possible.
My question: should I use an index on the column and if so, what kind of index?
I have done a little test with a function based index (inspired by this Tom Kyte article: http://tkyte.blogspot.com/2006/01/something-about-nothing.html):
create index text_isnull_idx on my_table(text,0);
I notice that if I use the clause WHERE TEXT IS NULL, the index is used. But if I use a clause WHERE TEXT IS NOT NULL (which is the clause I want to use), a full table scan is performed. Is this bad? Can I somehow improve the speed of this selection?
Thanks in advance,

catch(Exception exception)
out.println( "Exception: The item that you requested was not found in the cache" + "<BR>" );
toWrite = toWrite + "Exception : " + exception.getMessage() + "\n" ;
finally
// write to logfile
logFile = new WriteToLogFile();
logFile.setSourceDirName("blotter");
logFile.setQuery(request.getQueryString());
logFile.setServletPath(request.getServletPath());
if (toWrite!=null)
logFile.writeLog(getServletInfo(),toWrite);
out.println("</HTML>");
out.close();
// need the class name for log file
public String getServletInfo()
return this.getClass().getName();
}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. -
