LicenseServer property in Company object alway return empty string

Hi everyone,
When I use Company object and LicenseServer property to get LicenseServer, both in SBO 2004 & SBO 2005 all return empty string, who can help me get the correct LicenseServer name.
Thanks in advance.
Kathy

Jose Xabier,
Thanks for your reply, actually I need the License server name, but in SLIC table it saves Local hotost and port number some times like below:
[localhost:30000]
who knows how to get the name instead of Localhost,
why licenseserver return empty sting? doI need set other property to get license server name for company object?
Thanks,
Kathy

WINE err:"wine cmd.exe /c echo '%ProgramFiles%' returned empty string"

So as the tittle states WINE is throiwng this error:
wine cmd.exe /c echo '%ProgramFiles%' returned empty string
As for what might have caused it? probably the last system update which was performed a few days ago, my old prefix works fine but I have a habit of creating new prefixes for troublesome applications, or applications I am unsure of whether they will cause trouble or not.
Hence I created a new prefix using:
export WINEARCH=win32
export WINEPREFIX=~/.problematic
winecfg
As for how wine is run, it's run as a normal, unprivileged, user.
Oh and I also tried generating yet another prefix like this:
$ WINEARCH=win32 WINEPREFIX=~/.problematic-new winetricks steam
Executing w_do_call steam
wine cmd.exe /c echo '%ProgramFiles%' returned empty string
Didn't work either.
I'm at loss, any suggestion on how to fix it?

$ WINEARCH=win32 WINEPREFIX=~/testprefix notepad.exe

So obviously I need to correct the command
$ WINEARCH=win32 WINEPREFIX=~/testprefix wine notepad.exe

wine: configuration in '/home/shiina/testprefix' has been updated.
Wine cannot find the ncurses library (libncursesw.so.5).
why is ncurses a dependency anyway? besides, wicd-curses works so this shouldn't be the case.
Anyway, trying winetricks in the same prefix
$ WINEARCH=win32 WINEPREFIX=~/testprefix winetricks steam
Executing w_do_call steam
wine cmd.exe /c echo '%ProgramFiles%' returned empty string
Anyway, I expected notepad to work since it resides in %WINDOWS% not %ProgramFiles%
Is there any registry key I can set for this? all my google searching says this can cause with a mismatch of wine versions but why would that happen?
Either way checking wine --version outputs wine-1.7.20 which is the same as it was pre-update (when it still worked).

Min aggregate function returns empty string

I have a data set with a column named "month" which contains string values like 1,2,3... etc. including empty string. When I apply an aggregate Min function like below, it returns empty string instead of 1. or the lowest month number.
Min(Fields!month.Value, "Financial")
Please if any one can assist me on this.
Regards

Hi ABDUL-HAFEEZ,
As you know the Min() function returns the minimum value of all non-null numeric values specified by the expression, because you have null string in the field and also the field type is string but not numeric, so this function will not works fine.
I have tested on my local environment that we can get the first convert the string to numeric type value and then get the min value of the month field by using the query not the expression.
Details information below for your reference:
Create an new dataset(DataSet2) to get the minimum value from the Month and the query like below:
SELECT Min(CAST(Month AS INT)) as NewMonth
FROM TableName
Using below expression in the main dataset will display the minimum value of the month:
=Sum(Fields!NewMonth.Value, "DataSet2")
If you still have any problem, please feel free to ask.

APEX_UTIL.GET_PRINT_DOCUMENT always returning empty BLOB

Dear community,
I have a huge problem when using the function APEX_UTIL.GET_PRINT_DOCUMENT in a job or database procedure.
The following code runs perfectly when I integrate it in the APEX application directly e.g. using a button to execute it (of course I use an anonymous PL/SQL block in APEX itself). But when I run the same code as a procedure or job in the APEX database itself I always receive a mail with an empty PDF:
CREATE OR REPLACE PROCEDURE APEX_DRUG_SAFETY.CALL_MAIL
is
l_id number;
l_document BLOB;
BEGIN
wwv_flow_api.set_security_group_id;
l_document := APEX_UTIL.GET_PRINT_DOCUMENT
+(+
p_application_id=>'105',
p_report_query_name=>'TestReport',
p_report_layout_type=>'pdf',
p_document_format=>'pdf'
+);+
l_id := APEX_MAIL.SEND
+(+
p_to        => '[email protected]',
p_from      => '[email protected]',
p_subj      => 'sending PDF via print API',
p_body      => 'Please review the attachment.',
p_body_html => 'Please review the attachment.'
+);+
APEX_MAIL.ADD_ATTACHMENT
+(+
p_mail_id    => l_id,
p_attachment => l_document,
p_filename   => 'mydocument.pdf',
p_mime_type => 'application/pdf'
+);+
wwv_flow_mail.push_queue(
P_SMTP_HOSTNAME => 'DESMTP.TEST.COM',
P_SMTP_PORTNO => '25');
end;
The problem is that the function APEX_UTIL.GET_PRINT_DOCUMENT always returns an empty BLOB when executed outside of the APEX application. I found this issue in several other posts in this forum but I did not find a solution.
The mail transmission itself works perfectly. Also with an attachment if e.g. I use another BLOB already stored in the database for testing purposes. So it is not the mail transmission that causes the problem but the empty variable l_document that is still empty.
Thanks in advance for the help.

you should be using this

    apex_util.set_security_group_id (p_security_group_id => l_workspace_id);

POSTING TO JSP FORMS GIVES NULL OBJECT RATHER THAN EMPTY STRING

This post is for Dan Norris of DOE. He brought this up in a submitted tar, but it is addressed by the PDK community here.
We arehaving problems using the standard HTTPServletRequest getParameter
methodinside of the portal.
The standard for this method is as follows:
*If you usethis method to read from a text field without any text in it, you
get an empty string. ( "" )
*If you use it to read from a text field with text in it youwould get the
corresponding text.
*If you try to read from a field that doesn'texist then and only then would
you get a Null object.
On our portal server itis behaving differently inside of portlets.
* If you use this method to readfrom a text field without any text in it, you
get a Null Object
* If you use itto read from a text field with text in it you would get the
correspondingtext.
* If you try to read from a field that doesn't exist you also would youget a
Null object.
Also, on the same server If you access a simple JSP directlywithout the it
being a portlet, it behaves as defined by standard Javadocumentation.
Test case:
Create test.jsp with these contents:
========start test.jsp
<%@pageimport = "oracle.portal.provider.v1.*,
oracle.portal.provider.v1.http.*"%>
Form to test submission of empty form field.<br>
Text Field Value ="<%=request.getParameter("testField")%>"
<form name="test" action="<%=
HttpPortletRendererUtil.htmlFormActionLink(request,PortletRendererUtil.PAGE_LINK
) %>">
<%=
HttpPortletRendererUtil.htmlFormHiddenFields(request,PortletRendererUtil.PAGE_LI
NK) %>
<INPUT type="text" name="testField">
<INPUT type="Submit"name="Submit">
</form>
========end test.jsp
=================startprovider.xml
<provider class="oracle.portal.provider.v1.http.DefaultProvider"
session="true">
<portlet class="oracle.portal.provider.v1.http.DefaultPortlet" version="1" >
<id>1</id>
<name>TestPortlet</name>
<title>Test</title>
<description>Test</description>

<renderContainer>false</renderContainer>
<showPage>test.jsp</showPage>
<pageParameterName>next_page</pageParameterName >
</portletRenderer>
</portlet>
</provider>
=================end provider.xml
After you have theprovider added to the portal, login to the portal as
portal30 and go toAdminister Tab->Display Portlet Repository and display the
portlet.
1.Enter "test" in the text field and submit.
2. Returns Text Field Value ="test"
3. Submit form leaving the text field empty.
4. Returns Text FieldValue = "null"
Submitting the form with the text field empty should returnvalue of "", and
not "null".

fyi in case anyone else ever wants to know:
I found it... the details I was looking for were in the OC4J 9.0.2 Release Notes:
Display of null values in JSP.
In Oracle9iAS, a null value printed from a JSP page displays, by default, as
the string "null." To display nothing instead, set the attribute jsp-print-null
to false in the <web-app> element of
global-web-app.xml or orion-web.xml.

Cfexchangemail fromID returns empty string

I'm trying to create a "Reply with Template" bit of code and since Outlook 2007 doesn't have this capability, I thought I'd try the cfexchange tags to view the mail, pick a reponse and cfmail to send.
We're using SBS 2008 & CF8 with all hotfixes
I have the following basic code
<cfexchangemail action="get" name="weeksmail" connection="myconn" />
<cfdump var="#weeksmail#">
This returns email correctly (can read the messages) but in something like 1/2 of the messages the Fromid reads [empty string]The other half is populated correctly.
If I can't get the fromID I can't populate the TO: in cfmail so I can't do what I'm trying to do.
I can't see anything in the email themselves that would account for this. Any Ideas?

Can you please post your query / stored procedure you are using? Very possible reason includes one among your substring (within the concat) is null and making the final output to be null. Size, esp 800 shouldn't matter.

Checking an object in Arraylist against empty string

Hi all,
Im storing a collection of objects in Arraylist.Among them , one of the objects has an empty string.How can i check whether an object contains empty string.I tried to check using the follwing snippet:
ArrayList idList=new ArrayList();
if((idList.get(0)) == null || idList.get(0) == "")
        Debug.log("*****ARRAY LIST IS BLANK 1********");Please help

Here is a bit more deeper code:
HashMap lookupMap= null;
try {
          Object obj = util.lookUp(pid,attributeId,params); // The lookUp method returns an object.
             Debug.log(11, " obj type: " + obj.getClass().getName());
        lookupMap = (HashMap) obj;
Collection mapkeys = lookupMap.keySet();
Iterator itKeySet = mapkeys.iterator();
ArrayList idList = new ArrayList();
ArrayList descList = new ArrayList();
ArrayList lookupKeys = new ArrayList();
while(itKeySet.hasNext())
        lookupKeys.add(itKeySet.next());
for(int i=0; i<lookupKeys.size(); i++)
        String key = (String)lookupKeys.get(i);
    if(key != null && key.startsWith("1_"))
          idList =(ArrayList)lookupMap.get(lookupKeys.get(i));
        if(key != null && key.startsWith("2_"))
          descList=(ArrayList)lookupMap.get(lookupKeys.get(i));
        if(key != null && key.startsWith("1_") && (size == 1))
           descList=(ArrayList)lookupMap.get(lookupKeys.get(i));
ArrayList id1=new ArrayList();
int x=0;
      do
     if(!(idList.get(x)).equals(null) || !(idList.get(x)).equals(""))
                id1.add(idList.get(x));
                Debug.log("*****idList.get(x)********"+idList.get(x));
                Debug.log("*****added to idlist.get(0)********");
                break;
              else
                x++;
     }while(id1.size() == 0);

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 AM

I 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
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>

</html>The converter is declared for the String class in the faces configuration file. From the log message is appears to be invoked, however the object is not set to null.
I tested this with JSF 1.2_04-b20-p03 as well as 1.2_09-b02-FCS.
any other suggestions what could be causing this.

Differnce between null string and an empty string??

what is the major difference between null string and an empty string??
I wrote the following simple program and I could see some different output.
Other than that, any other differences that we should pay attention to???
C:\>java TestCode
Hello
nullHello
public class TestCode
     public static void main(String[] s)
     {     String s1 = "";
          String s2 = null;
          System.out.println(s1 + "Hello");
          System.out.println(s2 + "Hello");
}

There's a big difference between the two. A null String isn't pointing to an object, but an empty String is. For example, this is perfectly fine:
public class TestCode
    public static void main(String[] args)
        String s = "";
        System.out.println(s.length());
} It prints out 0 for the length of the String, just as it should. But this code will give you a NullPointerException:
public class TestCode
    public static void main(String[] args)
        String s = null;
        System.out.println(s.length());
} Since s isn't pointing to anything, you can't call its methods.

Why buildODataEntryRequestBody always return an empty body

We are developing a demo project to create a new travel expense report through SMP 3.0 iOS SDK. The call to get a trip detail works. Then we use the schema to build the post body for creation.
For unknown reason, the buildODataEntryRequestBody call always returns an empty body. Could somebody help on this issue?
Thanks.

Its a little abstruse, don't you think?
Assuming you are using Jdev11g, and Faces;
I don't think there are any default 'double-click listeners' ; so that would mean, you are using client listener for dbclick event. If yes where and how are you calling your getSelectedRowKeys method?

[svn:bz-trunk] 11030: Tweak the deserialization of ASObjects to treat an empty string for the type of an object as null .

Revision: 11030
Author:   [email protected]
Date:     2009-10-20 11:35:02 -0700 (Tue, 20 Oct 2009)
Log Message:
Tweak the deserialization of ASObjects to treat an empty string for the type of an object as null. It appears that there is some logic in the LC remoting code that relies on a non-null class name to always exist. This change reverts to the old behavior of not allowing empty string as a value for the ASObject.namedType.
This should fix bug 2448442 and its duplicates caused by the recent serialization changes.
I don't think this is the perfect fix. Pending further investigation, a better fix would be either:
a. If it's OK to assume that empty string should always mean null for the type of the ASObject, the code that enforces it should be in the setter/getter inside ASObject and not in the deserializer.
b. ASObject doesn't guarantee that a named type exists or is valid. In that sense an empty string is as bad as some random characters that cannot be a valid class name in java, so depending on how disruptive it may be, the fix should be in any logic that uses ASObject.getType().

Hi Pavan,
"In your payload there is no namespace prefix for the elements under PayloadHeader element."
Yes, you are right - but this message is standard AQ Adapter Header message - it's not defined by me. I just used message which was automatically added to my project when I have defined AQ Adapter.
"In your process is the default namespace is same as namespace value of tns ??"
Do you mean targetNamespace? If yes it's different as it points to process "targetNamespace="http://xmlns.oracle.com/PF_SOA_jws/PF_APPS/APPS_PROCESS" (names of application and process have changed as I try different ways to do that)
ns1 is: xmlns:ns1="http://xmlns.oracle.com/pcbpel/adapter/aq/PF_SOA/PF_APPS/PO_AQ"
"another thing is tns and ns1 should have same values.."
When I create a variable of header type, namespace ns1 is automatically created for it. I set it as property of receive activity. When process is instantiated on the serwer I get the error in which you can see that namespace is tns.
Maybe I'm doing something wrong but I don't see how I could fix this in my process.
You can see that the message I get on the server has nothing in common with the application/project/process names. Is it possible to define such variable?
Regards
Pawel
PS:
In Transformation xsl file, both variables (source and target) has tns namespace for Header and PayloadHeader, and no namespace for subfields.

EntryProcessor invokeAll returning empty ConverterMap{}

Hi All,
I am trying to write a custom entryprocessor and whatever I return from the invokeAll method in the entryprocessor, I am always getting a empty ConverterMap{}. The code for the entryprocessor is as below:
public class CustomEP implements PortableObject, EntryProcessor {
     public CustomEP (){
public Map processAll(Set entries) {
          Map results=new HashMap ();
results.put ("1", "1");
System.out.println("Inside process All method");
          return results;
public Object process(Entry arg0) {
          Map results=new HashMap ();
results.put ("1", "1");
System.out.println("Inside process method");
          return results;
The client code to invoke this entryprocessor is as below:
Map results=cache.invokeAll(AlwaysFilter.INSTANCE, new CustomEP());
The processAll method on the Coherence nodes is invoked but if the print the results on the client side it return empty ConverterMap{}
On the other hand, if I invoke process method of CustomEP as below:
Map results=(Map) cache.invoke(AlwaysFilter.INSTANCE, new CustomEP());
I get the desired results. Please help me with the details why it is happening this way when the return type of the processAll is a Map.
Thanks a lot!
Regards,
S

Hi Robert and JK,
Thank you for your reply and time!
I could not find these details in any of the documentation that specifies keys passed in the result should be subset of the keys passed to the processAll method. Anyways, my problem is to invoke server-side code (avoid de-serialization) by passing a filter and then create a entirely new map (key and value will be different from the entries extracted from the passed filter) by reading the data from the passed entries. How can I implement it?
I am thinking to use aggregator as they are read-only and faster but again how to implement it using:
public Object aggregate(Set entries){
Again, I am getting an empty Map so is it necessary that the object returned should have keys matching the set of the entries passed to this method.
Secondly, there are other methods such as, finalizeResult() and init() if I extend AbstractAggregator, do I need to implement them and if yes, how? The entries set passed to the aggregate() method may not reside on the same node.
Please advise!
Regards,
SHi S,
the process() return value object, or the entry value objects in the map returned by processAll() can be arbitrary objects. So you just return a map from process(), and return a map as the entry value in the result map from processAll().
The AbstractAggregator has a fairly badly documented contract in the Javadoc (does not properly cover the values received in different scenarios for invocation). You should probably read the section about it in the Coherence book, that explains leveraging AbstractAggregator in significantly more details. It also happens to be in the sample chapter, but I recommend reading the entire book.
I am not sure about the issues relating to posting links to PDFs on Packt's webpage, so I won't do that. Please go to Packt's webpage (http://www.packtpub.com ), look for the Coherence book there and download the sample chapter (or order the book).
In short, all 3 to-be-implemented methods (init(), process(), finalizeResult()) in AbstractAggregator are called both on the server and on the caller side. You can distinguish which side you are on from looking at both the passed in fFinal boolean parameter and the m_fParallel attribute tof the aggregator instance.
There are 3 cases:
- non-parallel aggregation processing extracted values (m_fParallel is false, I don't remember what fFinal is in this case),
- parallel aggregation storage side processing extracted values (if I correctly remember, m_fParallel is true, fFinal is false),
- parallel aggregation caller side processing parallel results (m_fParallel and fFinal are both true).
Depending on which side you are on, the process method takes different object types (on server side it receievs the extracted value, on caller side it receives a parallel result object instance).
You SHOULD NOT override any of the other methods (e.g. aggregate() which you mentioned).
The advantage of this approach is that the AbstractAggregator subclass instance can pass itself off as a parallel-aggregator instance.
You should put together a temporary result in a member attribute of the AbstractAggregator subclass, which also means that it will likely not be thread-safe, but at the moment it is not necessary for it to be thread-safe either as it is called only on a single-thread.
Best regards,
Robert

Hi;
I used Fiddler to monitor the process, and it showed the request sent thru web service worked and returned a value, but in my .Net application the return captured as NULL. Could you please look into the code above and the result from Filddler and see if
you can help.
thank you.

Bc4j:RowScope on a Master Detail page always returns 0 rows for detail

Hi,
I have a problem with a Master Detail page that is called from another page. The Master Detail page has two View Objects, Budgets and Budget Versions. These are linked properly in BC4J and when I use these VOs together I can navigate through the Budgets (master) and the Budget Versions (details) are populated correctly.
However, I want to navigate to this page from another page which lists all possible Budgets. I pass the key of the selected Budget to the Master Detail page and the correct Budget is displayed, BUT the Budget Versions are NOT displayed - I get 0 rows returned.
The mechanism I use to pass the selected Budget ID to my Master Detail page is:
<ctrl:property name="key">
<ctrl:selection name="ViewTable" key="key"/>
</ctrl:property>
My BC4J Registry is set up as follows:
<bc4j:registryDef>
<bc4j:rootAppModuleDef name="BudgetModule"
defFullName="BudgetPackage.BudgetPackageModule"
configName="BudgetPackageModuleLocal"
releaseMode="stateful">
<bc4j:viewObjectDef name="ItiBudgetsView1">
<bc4j:rowDef name="CurrentBudgetRow" usesCurrency="True">
<bc4j:propertyKey name="key"/>
</bc4j:rowDef>
</bc4j:viewObjectDef>
<bc4j:viewObjectDef name="ItiBudgetVersionsView2" rangeSize="15"/>
</bc4j:rootAppModuleDef>
</bc4j:registryDef>
I then use
<bc4j:rowScope name="CurrentBudgetRow">
to get the correct Budget row in my master VO. But this always returns 0 rows in my detail VO. If I comment out the rowScope element, I don't get the desired Budget row, but I do get the correct Budget Version rows displayed. Is the rowScope element on the Budget VO interfering with the Budget Version VO?
Hope this is not too confusing!!
Thanks,
Steve

Steve,
I tried to create a comparable set of two pages and initially ran into the same problem. I just realized that my issue (which I hope is yours too) is that the rootAppModule name was different across my two pages. This led to each page having its own application module instance, so the currency was different on each page.
By changing all of my pages to use the same application module name (in the registryDef, in the appModuleScope tags in the page, and in the findAppModule tags in the handlers), I resolved this problem.
My event handler to go to the master/detail page from the master page, FYI, looks like this:
