Declaring a Node object throws null...how to handle if Node doesnt exist

Hello all,
I am parsing an xml document that looks like the following:
<item>
       <title>
       </title>
       <link>
       </link>
       <description>
       </description>
       <pubDate>
       </pubDate>
       <geo:lat>
       </geo:lat>
       <geo:long>
       </geo:long>
</item>Now every item may or may not contain the two geo nodes.
<geo:lat> and <geo:lon>
When I declare those two nodes and they are not present:
Node geoLonNode = geoLatNode.getNextSibling().getNextSibling();//ERROR HERE.
String geoLonText = geoLonNode.getTextValue();I get a null pointer exception.
How can I handle this exception.
Is there a way to test for null before declaring the Node obj?
Basically what I am trying to do is to output the xml to a html table.
I imagine this would be simple, I am just at a loss.
TIA!

Nevermind...as I said it was probably easy and it was.
Long day!
if(geoLatNode.getNextSibling().getNextSibling() != null)
Node geoLonNode = geoLatNode.getNextSibling().getNextSibling()
String geoLonText = geoLonNode.getTextValue();
}Thanks for looking.

How to handle the Exception in GP using executable callabel object.

Hi all,
I handled an exception in GP using Background callable Object. That is working fine.
(Ex: Exception_No_User_Found). The Problem is I am not able to handle the exceptions for normal callable object. I have done the same thing as i did in background callable object except implementing IGPBackgroundCallableObject Class. I have created an WebDynpro DC Project where in getDescription method i declared an Exception and in execute method of component controller I caught the exception if no user found.
Then i created an callable object for this simple DC project. but that is not working i could not catch the exception. when i execute the process it is asking the User ID if i give the wrong userId it is not refreshing back to the user id input form.
But if i test that simple callable object separately it is throwing an Exception when I give the wrong input..
but the same thing is working fine using background callable object.
I couldn't handle the exception for the simple callable object or executable callable object.
Please If anyone bring me the solution that would be appreciated.
Thanks in advance.

Malar.

Hi Shikhil
Thanks for your reply
Please have a look below for exceptions which i am getting in GP and let me know how to handle these exceptions.
1) "Activity could not be read"
2) "Action has been stopped"
3) error while processing the item can not be displayed
if you give any idea/clue how to handle these exceptions then it would be great help to me
Thanks

Why it is throwing null at last whenever i am running this program

public static void main(String args[])
          String str;
          try
          FileReader fis = new FileReader(C:\\src\\vinaysingh\\xmlreq.xml");
          BufferedReader br= new BufferedReader(fis);
          do
               str=br.readLine();
               System.out.println(str);
          while(!str.equals(null));
why it is throwing null on last if i am reading any xml file

get the value of string as the value which u
had collected from the string instead of nullWhat? That just doesn't make any sense. At all.
I presume what you're asking is:
How do I read lines from a text file, ignoring empty lines. Especially how do I know when I've reached the end of the file so that I can stop trying to read more lines.
this might help some ...

[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.

WPUMFactory.getUserFactory() throws null pointer exception

Hi,
I am trying to use KM API's to read files from KM repository. I am using the below code as mentioned in the blog: How to download KM documents using Web Dynpro Java
Below is my code:
IWDClientUser wdClientUser = WDClientUser.getCurrentUser();
com.sap.security.api.IUser sapUser = wdClientUser.getSAPUser();
IUser epUser = WPUMFactory.getUserFactory().getEP5User(sapUser);
However the line WPUMFactory.getUserFactory() throws null pointer exception. Can some one please help on why these happens as these seems to be the standard code to read a file from KM.
Thanks.
Regards,
Ponraj M

Hi Ponraj ,
Instead of fetching the current logged on user , use the below line to set the resource context and see if it helps .
com.sapportals.wcm.repository.IResourceContext resourceContext = ResourceFactory.getInstance().getServiceContext("cmadmin_service");
cmadmin_service is a existing user that can be used to access KM resources .

Does making objects equal null help the gc handle memory leakage problems

hi all,
does making objects equal null help the gc handle memory leakage problems ?
does that help out the gc to collect unwanted objects ??
and how can I free memory avoid memory leakage problems on devices ??
best regards,

Comments inlined:
does making objects equal null help the gc handle
memory leakage problems ?To an extent yes. During the mark phase it will be easier for the GC to identify the nullified objects on the heap while doing reference analysis.
does that help out the gc to collect unwanted objects
??Same answer as earlier, Eventhough you nullify the object you cannot eliminate the reference analysis phase of GC which definitelely would take some time.
and how can I free memory avoid memory leakage
problems on devices ??There is nothing like soft/weak reference stuffs that you get in J2SE as far as J2ME is concerned with. Also, user is not allowed to control GC behavior. Even if you use System.gc() call you are never sure when it would trigger the GC thread. Kindly as far as possible do not create new object instances or try to reuse the instantiated objects.

How OSB handling null element?

hi Guys,
I having question about how to handling a null node during trasnfortation and mapping using oracle workshop for OSB 10g.
Well i have a consumer that not sending the element into the proxy, so during the proxy i will need to transform it into null element to the provider. what's in my mind is transform the element tag into something like this
{ if (fn:nilled($getAssetAttribReqParam1/RequestHdr/ns1:RequestId)) then
<ns1:RequestId xsi:null = "true"/>
else
(<ns1:RequestId>{ data($getAssetAttribReqParam1/RequestHdr/ns1:RequestId) }</ns1:RequestId>)
but when i doing testing it still showing this
<ns1:RequestId></ns1:RequestId>
i will need to sent the element something like this to the provider. because if this element is date format it will fail in the validation if i sending *<ns1:RequestId></ns1:RequestId>*
<ns1:RequestId xsi:null = "true"/>

I think your case should be addressed like -
if ($getAssetAttribReqParam1/RequestHdr/ns1:RequestId) then
<ns1:RequestId>{ fn:data($getAssetAttribReqParam1/RequestHdr/ns1:RequestId) }</ns1:RequestId>
else
<ns1:RequestId/>

right click on the element on element panel on the right and choose rename. Or rename on the left panel on the top. You can give them any name you like just do not start with a number or special character.

Unable to get value of the property 'nodeName': object is null or undefined Error in apex_ns_3_1.js

I am getting the following error with IE9 and Firefox 26 with application express 3.2:
SCRIPT5007: Unable to get value of the property 'nodeName': object is null or undefined
apex_ns_3_1.js, line 589 character 10
this.dialog.check2 = function (e){
var tPar = html_GetTarget(e);
var lEl = $x('apexir_col_values_drop');
var l_Test = true;
****** while(tPar.nodeName != 'BODY'){
tPar = tPar.parentNode;
if(tPar == lEl){l_Test = false;}
if(l_Test){$x_Remove('apexir_col_values_drop')}
This happens when I click the Gear Icon, then Filter, then I click the dropdown arrow under expressions and pick an expression from the list.
If I set (through IE Developer tools) back to IE8 mode, I don't get the error.

Guess no one is using 3.2 any longer or no one else gets this error..... Guess I can edit the JavaScript file to trap the error since it really doesn't seem to cause an issue. Just didn't want to have to go that route.

the last Alert (accessing t2) got always a null pointer, the fist Alert works fine and print out the string i expected to see
call in ActionScript
    public function loadTT():void {
       _policyService.getTT(loadTTHandle);
    private function loadTTHandle(content:TT1):void {

       Alert.show("" + content.t2.t2s);
is it possible to access a nested complex type? i only could find simple examples.
thanks for your help joe

How to handle the call transaction in method of a custom business object

Hello all,
There is a custom report " RPTCORAPP" for approving leaves . As per my requirement i have develop a copy of leave workflow and for approval process i have call "RPTCORAPP" in Custom method of custom object. i have made a transaction for this custom report for approving attendances. I am calling this method though call transaction statement within method.
Problem: while approving the attendance workitem is not disappearing from the portal. Problem is due to call transaction statement.
               once workitem come to the user, user click on it. control goes to the report, which display all the leave to approve on
               the portal.
               If after approving/ rejecting attendance user close the screen.workflow remain in the "process" status.Control wont come back after call transaction statement in the method.
             At the same time if user clicks on back button inspite of closing the screen. it is working fine. workitem disappears from the portal.
How to handle the scenarion. if after approving/rejecting, i want the control to come back to the NEXT STATEMENT after call transactionstatement in my method.
Please help it out........:)

Hi swami,
thanks for reply. but i am not using BDC in my method. iam just calling a custom transaction thriugh statement
Call transaction 'ZHR_APPROVE_CLINOUT'. This transaction directly run the report RPTCORAPP and display all the request.

Weblogic throwing "null SOAP element Exception" in multi-part SOAP response

Hi All,
I'm using weblogic 10. My application is a webservice client generated using '*clientgen*', which is running on weblogic, and
is invoking a remotely hosted webservice ( Remotely hoseted webservice may not be running on weblogic).
I've the wsdl file of remotely hosted webservice.
Now the problem is with WSDL file (I suppose), have a look at this.
*<message name="m1">*
*<part name="body" element="tns:GetCompanyInfo"/>*
*</message>*
*<message name="m2">*
*<part name="body" element="tns:GetCompanyInfoResult"/>*
*<part name="docs" type="xsd:AnyComplexType"/> ------> assume all elements inside this complex type can be nil or minOccurs set to '0'*
*<part name="logo" type="xsd:AnyOtherComplexType"/> ------> assume all elements inside this complex type can be nil or minOccurs set to '0'*
*</message>*
<portType name="pt1">
<operation name="GetCompanyInfo">
<input message="m1"/>
*<output message="m2"/> -----> multi part message.*
</operation>
</portType>
Now here is sample message for the request(I've composed this message for this question):
<soap:Envelope> MESSAGE1
<soap:header/>
<soap:body>
<tns:m2>
<tns:GetCompanyInfoResult>
Blah Blah....
</tns:GetCompanyInfoResult>
<tns:docs>
Blah Blah....
</tns:docs> Assume no data for 'logo', so it's not returned. Since all its elements can be nillable.
<tns:m2>
</soap:body>
</soap:Envelope>
First of all, is this SOAP response is valid? I'm not sure about *'message' and 'parts' in SOAP*, but according to XML schema standards it's invalid.
Because, according to *'message' m2, 'logo' is missing*, eventhough all it's elements are nillable in such case there should be *<logo/>* at the end.
I mean valid message should be like below
<soap:Envelope> '*MESSAGE2*'
<soap:header/>
<soap:body>
<tns:m2>
<tns:GetCompanyInfoResult>
Blah Blah....
</tns:GetCompanyInfoResult>
<tns:docs>
Blah Blah....
</tns:docs>
*<tns:logo/> ------------------> here is the change compared to above message. empty element.*
<tns:m2>
</soap:body>
</soap:Envelope>
Now the concerns are :
(1) Which is a valid response? Message1 or Message2
(2) If message1 is valid then why is weblogic throwing an exception 'null SOAP element', I suppose this is due to missing 'logo' element.
(To confirm this I've used tcpmonitor and found message1 as response but weblogic is still throwing 'null SOAP Element' exception,
which confirms it needs 'logo' as well, I suppose <logo/> at least). Is there any workaround for this in weblogic for multi-part messages?
(3) If message1 is invalid according to SOAP standards then You've answered my question. ---> I need to talk to the webservice provider in this case.....
Thanks in advance...

Message 1 is not Basic Profile 1.1 compliant. It is specified by BP1.1 in section 4.4.1(http://www.ws-i.org/Profiles/BasicProfile-1.1-2004-08-24.html#Bindings_and_Parts) that when a wsdl:part element is defined using the type attribute, the serialization of that part in a message is equivalent to an implicit (XML Schema) qualification of a minOccurs attribute with the value "1", a maxOccurs attribute with the value "1" and a nillable attribute with the value "false".
