A Weird Class Reference Error

I have a class called Organization class derived from a class called Entity. And the organization class has a transient attribute called localAddresses. After updating the content of an instance of organization class, I get the following error when I want to display the updated instance in the session (web). I don't know why it refers the super class for the attribute localAddresses.
An error occurred while evaluating custom action attribute "items" with value "${entry.localAddresses}": An error occurred while getting property "localAddresses" from an instance of class com.abc.xyz.domain.Entry (java.lang.Exception: Local code is not set yet)The JSP code works when either creating a new instance of the Organization class and retrieving it from DB. The related JSP code is the followings:
<c:forEach var="address" items="${entry.localAddresses}">
</c:forEach>The instance is saved into the session.
Any possible causes?

organization class has a transient attribute called localAddresses
The instance is saved into the session. Could these be related in some way shape or form?
Transient attributes are not saved when the bean is serialized. So if the bean gets serialized/unserialized that attribute would not be available.
I don't recognise the exception - is it a custom one you have? What is the full stack trace?
What does your "getLocalAddresses" method look like?

Link between classes: Reference Error

Hi,
I am still trying to create a movie clip array to make a list of objects appear on stage and have the user interact with them.
This will be my game loop class called "LetterArray()".
My main class is called "BugGoopFSGame()".
After I add the line of code below into my LetterArray(). as class file I get the error message below:
Code entered:
private var lettersL1:Array = new Array[a,f,g,h,i,n,o,s,t];
This is the error message I get:
ReferenceError: Error #1069: Property [object T] not found on S and there is no default value.
    at LetterArray()
    at BugGoopFSGame()
I am sure the reference I use between the two files are not good. Can you please tell me what code I should add and where.
Thanks for your help!
Charine
This is the code in my main class - BugGoopFSGame()
package
    import flash.display.*;

if, for example, A is a class name, you should use "A" and then use getDefinitionByName() to retrieve the class reference from the string.

Java class reference error in Portal Application

Hello,
I have created a Portal Application Project with the Class
"public class TEST extends AbstractTestComponent implements ITestable"
in order to test the application.
The test works fine with a simple code.
Instead, using the external class HSSFWorkbook in order to create an excel file, the Enterprise Portal Unit Test return the following error:
"java.lang.NoClassDefFoundError: org/apache/poi/hssf/usermodel/HSSFWorkbook"
I have tried to put the ZIP file of class into the folder "dist/PORTAL-INF/lib" and "dist/PORTAL-INF/exlib" but it doesn't work.
Can someone tell me what I have to do?
Thanks and best regards,
Matteo.
Edited by: Matteo De Santis on Feb 10, 2009 7:22 PM

Hi,
note that a portal application has two classloaders. one for the public part (src.api) and one for the private one (src.core).
portal components reside in src.core by default. this means you need to load your jar file to the private class loader.
so instead of dist/PORTAL-INF/lib use dist/PORTAL-INF/private/lib

How to use application class reference in the controller methods of BSP

Hi,
I have created a bsp application and also created an application class and assigned it to the application class. In the application class, I have created attribute TEXT type string(public and instance parameter).
In the controller let's say main.do, I am trying to give a value to to the text by adding the following code.
application->text = 'test'.
I am getting syntax error saying field 'text' is unknown. It is not contained in one of the specified tables nor defined by DATA statement.
Please can someone let me know how to use the application class in the coding with an example. I couldn't find how exactly this has to be reference. Please help.
Best regards
Siva

Hi,
if you are having main controller and sub-controller then you may need to use below coding to use application class reference.
*Data declaration
DATA: obj_cntrl        TYPE REF TO cl_bsp_controller2,
         obj_sub_cntrl   TYPE REF TO z_cl_sub_cntl,
         application TYPE REF TO z_cl_application.
*Get the controller
CALL METHOD obj_main_cntrl->get_controller   "obj_main_cntrl is the object of main controller
    EXPORTING
      controller_id       = 'SUB'   "Controller ID
    RECEIVING
      controller_instance = obj_cntrl .
obj_sub_cntrl ?= obj_cntrl .
application ?= obj_sub_cntrl ->application.
or simply use below code in your controller method.
application ?= me->application.

StartTransmit / stopTransmit reference error on NetStream when connecting to device

Hi all,
I'm trying to create a P2P connection between a mobile device (Android) and a PC using the NetStream class.
When the connection is established, the Flash Player Instance on the PC is crashing with a reference error:
“Property startTransmit not found on flash.net.NetStream”
I have seen the thread located located here: http://stackoverflow.com/questions/9676496/adobe-cirrus-error-on-direct-connectproperty-st arttransmit-not-found-on-flash-n
but was not successfull in making it work with my code.
I have tried extending the NetStream class like so:
import com.frimastudio.cosy.util.NetConsole;
import flash.net.NetConnection;
import flash.net.NetStream;
public class NetStreamProvider extends NetStream
public function NetStreamProvider (connection:NetConnection, peerID:String)
   super(connection, peerID);
// For AIR Android projects: when the device is put to sleep for a moment, this function will be
// called so we need to implement it to prevent flash from crashing.
public function startTransmit($p1:*, $p2:*):void
   COSY::console { NetConsole.WarningInternal("NetInterfaceSlot", "startTransmit", "startTransmit called"); }
public function stopTransmit():void
   COSY::console { NetConsole.WarningInternal("NetInterfaceSlot", "stopTransmit", "stopTransmit called"); }
and using the NetStreamProvider instead. Without success.
Any help would be greatly appreciated.
Thanks.

>> i suspect this is AIR-specific (probably if AIR is the sender) -- in my experience it doesn't happen with plain Flash Player.
[Guillaume] -> Right, it does not happen on NetStreams between 2 Flash Players and 2 AIR app. Only between AIR-FlashPlayer NetStreams. Basically, after a stream is opened between AIR and Flash Player, the AIR is calling "starTransmit" on the FlashPlayer NetStream, wich is not implemented.
>> try making an object with those method names and assign it to netStream.client
[Guillaume] -> I tried the following:
Implement starTransmit/stopTransmit functions in the NetStream.client object
Implement startTransmit/stopTransmit functions in the NetStream instance (subclassed)
Without success. Basically, it works fine if I just create a "dummy" client object for the NetStream that has those 2 functions. But If I want to use my own client it was still crashing.
I found a work around for my problem.
My NetStream object is sub classed as such:
public class NetStreamProvider extends NetStream
public var customClient:Object;
public function NetStreamProvider (connection:NetConnection, peerID:String)
   super(connection, peerID);
   customClient = new Object();
   this.client = customClient;
   // Implement startTransmit and stopTransmit here for dummy client
   customClient.onPeerConnect = function(subscriber:NetStream): Boolean{
    var subClient:Object=new Object();
    subClient.stopTransmit=function($p1:*,$p2:*):void{
     trace("Cosy: stopTransmit called",$p1,$p2);
    subClient.startTransmit=function():void{
     trace("Cosy: startTransmit called");
    subscriber.client = subClient;
    return true;
public function SetClient(c:Object):void
   this.client = c;
public function OnNetStreamAsyncError(event:AsyncErrorEvent):void
And in the stream status event handler, when the stream is ready (events "NetStream.Play.PublishNotify" and "NetStream.Play.Start") I set the correct client, which has the receive handler. At that point startTransmit was already called:
And in the stream status event handler, when the stream is ready (events "NetStream.Play.PublishNotify" and "NetStream.Play.Start") I set the correct client, which has the receive handler. At that point startTransmit was already called:
private function OnNetStreamStatus(e:NetStatusEvent)
switch(e.info.code)
case "NetStream.Play.PublishNotify":
           stream = e.target as NetStreamProvider;
           stream.SetupClient(client);
break;
case "NetStream.Play.Start":
           stream = e.target as NetStreamProvider;
           stream.SetupClient(client);
break;
At this point, i'm not blocked anymore. However, it would be good to know why, when and who are calling those functions to understand the issue. this is not documented anywhere, and might be an issue to a lot of people now that we are starting to see more and more cross-platform connectivity.
Cheers.

Java Embedding Weird XML Node Error

Ok, I am going crazy. I have a java embedding node that takes a date string in, changes it to a different format and creates another date that contains the current time. if I run this in java to code run ok and there are no issues. At the end of the java I print out the string and they are exactly what I want. The thing that is going on is when I set the 2 string BPEL variables in the java embedding, when I try to reference them the 2nd time,I get a weird node object error. I get through the first pass ok. when I try to reference Test1 or Test2 on the 2nd pass I get the error below. Its like when I set the variable currentDB2UpdateDate and currentDB2CurrTimeDate it does something to them. Instead of setting it to just the string it seems to set it to some kind of object.
I have 3 steps here. Assign -> Java Embedding -> Assign.
Assign 1 => Initialize 2 String variables to X.
<code>
<assign name="Assign_2">
<copy>
<from expression="string('X')"/>
<to variable="currentDB2UpdateDate"/>
</copy>
<copy>
<from expression="string('X')"/>
<to variable="currentDB2CurrTimeDate"/>
</copy>
</assign>
</code>
Java Embedding =>
<code>
String currentFileDate = (String)getVariableData("currentFileDate");
String currentDate = "";
try
SimpleDateFormat sdfSource = new SimpleDateFormat("MM/dd/yyyy");
Date date = sdfSource.parse(currentFileDate);
SimpleDateFormat sdfDestination = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
currentFileDate = sdfDestination.format(date);
catch(ParseException pe)
System.out.println("Parse Exception : " + pe);
try
Calendar cal = Calendar.getInstance();
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
currentDate = sdf.format(cal.getTime());
catch(Exception pe)
System.out.println("Parse Exception : " + pe);
System.out.println("currentFileDate : " + currentFileDate.toString());
System.out.println("currentDate : " + currentDate.toString());
setVariableData("currentDB2UpdateDate",currentFileDate);
setVariableData("currentDB2CurrTimeDate",currentDate);
</code>
Assign 3 =>
<code>
<assign name="Assign_1">
<copy>
<from variable="currentDB2UpdateDate"/>
<to variable="Test1"/>
</copy>
<copy>
<from variable="currentDB2CurrTimeDate"/>
<to variable="Test2"/>
</copy>
</assign>
</code>
<code>
<bpelFault><faultType>0</faultType><selectionFailure xmlns="http://schemas.xmlsoap.org/ws/2003/03/business-process/"><part name="summary"><summary>Invalid to part type.
When performing the assign operation, the to node 2010-07-17 12:00:00 is invalid.
The node named in the error message was either null or an empty node set, and it was not an instance of org.w3c.Element.
Verify the node value at line number 819 is not null and is an instance of org.w3c.Element.
</summary></part></selectionFailure></bpelFault>
</code>
The 2nd pass to this throws the following error when trying to set Test1 and Test2 again... Its like it is setting the variable to an object and not just the string. I tried using toString() in the setVariable too and it didn't work. I don't get it.

I am also facing a similar issue.There is selection failure in assignment to local variable of BPEL .
PFB the logs :
parts: {{
summary=&lt;summary&gt;Invalid to part type.
When performing the assign operation, the to node false is invalid.
The node named in the error message was either null or an empty node set, and it was not an instance of org.w3c.Element.
Verify the node value at line number 3577 is not null and is an instance of org.w3c.Element.
&lt;/summary&gt;}
Here is the code:
<copy>
<from expression="xpath20:add-dayTimeDuration-to-dateTime($calculatednpexectime,'P200YT')"/>
<to variable="calculatednpexectime"/>
</copy>
It seems as if Oracle is not accepting the date format .
Is there some issue with local variables of new version of BPEL ??

Class reference internal table

Hello Gurus,
i have an internal table filled with class references and i need to acces the one field of a structure of every class.
I am now trying something like this:
loop ref_table assigning <l_wrk_ref_but0id>.
      IF <l_wrk_ref_but0id>->m_str_but0id-type = /gkv/cd40_cl_const=>con_pkkv.
      ENDIF.
endloop.
I need the field "type" in the structure "m_str_but0id" of every class (reference) in the table. The error that i'm getting is: "Field m_str_but0id unknown".
Please help.
Ioan Constantin.

Hello Ioan
You have to access the field dynamically as well:
DATA:
   ld_structure TYPE <name of structure>,
   ld_attribute    TYPE tabname,
   ld_field          TYPE fieldname.
FIELD-SYMBOLS:
<ls_struct>     TYPE any,
<ld_fld>           TYPE any.
ld_attribute = 'M_STR_BUT0ID'.
ld_field       = 'TYPE'.
loop ref_table assigning <l_wrk_ref_but0id>.
     ASSIGN <l_wrk_ref>but0id>->(ld_attribute) TO <ls_struct>.
     ASSIGN COMPONENT (ld_field) OF STRUCTURE <ls_struct> TO <ld_fld>.
"      IF <l_wrk_ref_but0id>->m_str_but0id-type = /gkv/cd40_cl_const=>con_pkkv.
       IF ( <ld_fld> = /gkv/cd40_cl_const=>con_pkkv ).
      ENDIF.
endloop.
Even simpler might be the following approach:
LOOP AT ref_table assigning <l_wrk_ref_but0id>
                WHERE ( table_line->m_str_but0id-type = /gkv/cd40_cl_const=>con_pkkv ).
ENDLOOP.
" Assumption: Itab has class reference type as line type.

Thousands of reference errors in TCMRuntimeManager.as

I'm working on a fairly large AIR app and in the process of trying to find the cause of an out of memory error, I see that the class TCMRuntimeManager.as is throwing thousands of reference errors...just letting my app sit for 10 minutes had over 350,000 reference errors. The function checkTLFFontsLoaded is the culprit. I'm not sure if the reference errors are directly related to the out of memory error, but I did notice that as I interact with the app not all the reference errors are getting garbage collected. If I stop interacting with the app and force garbage collection a few times they all get cleared, but I think that under normal use the garbage collector is getting overwhelmed and doesn't clear out everything, and thus eventually these errors start piling up and contribute to the out of memory error.
The way the project is built is Flash CS 5.5 is used to import psd files, I set up some linkage classes, then export as a swc. The psd text fields are imported as TLFTextFields. The swc assets are then used in a FDT project compiled with Flex SDK 4.5.1 with AIR SDK 3.1. There are 5 products, each with its own swf. The swfs are compiled as Flash browser swfs and they are debugged/profiled using the standalone Flash player. When I profile the individual swfs there are no reference errors. If I profile the main swf (using adl) without loading the individual swfs, there are no reference errors. It's only when one or more of the product swfs are loaded into the main swf that reference errors start piling up. I've tried conerting the static text fields into bitmaps and registering the fonts (all from the same swc) in each swf and it hasn't made the problem go away but the memory spikes are no longer so dramatic. Any ideas on what is the root cause of this error?

fl.text.TCMRuntimeManager was implemented by Flash pro. Please forward the question to http://forums.adobe.com/community/flash. Thanks!

Class path Error urgent Plz

Hi Guys,
I was trying to write an WD application to check connector connectivity in EP, I have included these jar files in class path "com.sap.portal.ivs.connectorservice_api.jar" and "GenericConnector.jar".
The codes are like
IConnection connection = null;
IConnectorService cs = (IConnectorService) PortalRuntime.getRuntimeResources().getService(IConnectorService.KEY);
IConnectorGatewayService cgs = cs.getIConnectorGatewayService();
connection = cgs.getconnection(Alias,request)
but as soon as I write this last line getconnection() I get error which is "Compilation unit indirectly references the missing type com.sap.portal.services.api.connectorgateway.IConnectorGatewayService(typically some required class file is referencing a type outside the class path)"
and this given below error comes when I build the project.
"The project was not built since its classpath is incomplete. Cannot find the class file for com.sap.portal.services.api.connectorgateway.IConnectorGatewayService. Fix the classpath then try rebuilding this project."
can any one please tell me how can I fix this problem.
Thanks in advance

And the second error is
Error: The project was not built due to classpath errors (incomplete or involved in cycle).
I tried to rebuild it and also repair it with project structure and classpath. so that it can find the missing libraries.
I checked it out in the properties of the project in Java Build path it is showing an error of build path entry is missing
Please can anyone help on this error.
I am stuck on this error for past a long time.

Hi
yes, I had the same issue and I found a solution.
You need to request a patch for BUG 9212862 (already corrected in WLS 10.3.3) and do the follwing:
javax.xml.ws.BindingProvider provider = (javax.xml.ws.BindingProvider)port;
java.util.Map context = provider.getRequestContext();
context.put(weblogic.wsee.jaxrpc.WLStub.POLICY_COMPATIBILITY_PREFERENCE, weblogic.wsee.jaxrpc.WLStub.POLICY_COMPATIBILITY_MSFT);
This will cause the SecurityMessageArchitect class of WLS to not send the SecurityTokenReference in the Soap security header.
Please note that is evidently a non-comformity to the specs of microsoft:
Please give a look at
http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0.pdf (8.3 Signing Tokens)
and also at:
http://www.oasis-open.org/committees/download.php/16768/wss-v1.1-spec-os-SAMLTokenProfile.pdf
(3.4 Identifying and Referencing Security Tokens)
A SAML key identifier reference MUST be used for all (local and remote) references to SAML 1.1
assertions. [...]
All conformant implementations MUST be able to process SAML assertion references occurring in a
<wsse:Security> header or in a header element other than a signature to acquire the corresponding
assertion. A conformant implementation MUST be able to process any such reference independent of the
confirmation method of the referenced assertion.
It follows that the .NET 3.5 is a non conformat implementation: I would gladly know which is the position of Microsoft on that.

Error building project using kXML2 - "Class loading error: Wrong name"

Hi,
I'm testing the XML-Parser KXML2 and downloaded the latest package, but the minimal version (kxml2-min.zip). I put this file into the directory "%j2mewtk%\apps\KxmlTest\lib" and wrote the lines
import org.kxml2.io.*;
import org.xmlpull.v1.*;
When I try to build the project with the Wireless Toolkit (v1.04) it spits out the following error:
Error preverifying class kxml2.io.KXmlParser
Class loading error: Wrong name
com.sun.kvem.ktools.ExecutionException: Preverifier returned 1
Build failed
I also tried the full package "kxml2.zip" but the same error occurs.
How can I get rid of this? Thanks in advance!

Okay, finally worked it out (hopefully). I unpacked the archive to a directory (say "%J2MEWTK%\apps\KxmlTest\tmpclasses") and then preverified them "manually":
%J2SDK%\bin\preverify.exe -classpath "%J2MEWTK%\apps\KxmlTest\tmpclasses";"%J2MEWTK%\lib\midpapi.zip" org.kxml2.io.KXmlParser
%J2SDK%\bin\preverify.exe -classpath "%J2MEWTK%\apps\KxmlTest\tmpclasses";"%J2MEWTK%\lib\midpapi.zip" org.xmlpull.v1.XmlPullParser
%J2SDK%\bin\preverify.exe -classpath "%J2MEWTK%\apps\KxmlTest\tmpclasses";"%J2MEWTK%\lib\midpapi.zip" org.xmlpull.v1.XmlPullParserException
Then I packed them again to a jar-file:
%J2SDK%\bin\jar.exe -cvf kxml2-min.jar %J2MEWTK%\apps\KxmlTest\tmpclasses\output\.
That was all!

I get a "JavaScript Application - Reference Error: XPCSafeJSObjectWrapper is not defined" error every time I try to open a new tab.

<blockquote>Locking duplicate thread.<br>
Please continue here: [/questions/777191]</blockquote><br>
Just like the title says, starting with Firefox 4 Beta 6 or 7, I forgot. Any time I try to open a new blank tab (sometimes even when I start up Firefox and the app tabs load) I get an error that says "JavaScript Application - Reference Error: XPCSafeJSObjectWrapper is not defined" If I close it everything works as normal again (until I open a new tab) but it is very annoying to have to do this. Is there any fix for this or is the bug just still there?

How can i use class reference from an array effeciently?

Hi,
I made some test here with getting a class reference from an array and using the reference's methods or variables.
Basically arrayEx is a container of type Array and it contains the Person's class instance in it. Num is a number extracted from the Person's instance
Example #1----Strongly typed
Var reference:Person;
Var num:int;
//Assignation
reference=arrayEx[0];-----IT IS SLOW HERE
//Use
num=reference.number --- IT IS FAST HERE
Example #2---Not typed
Var reference:*;
Var num:int;
//Assignation
reference=arrayEx[0]; ---- IT IS FAST HERE
//Use
num=reference.number ---IT IS SLOW HERE
No matter what i change in both code like casting Person on arrayEx, i cant seem to make them work both fast at the same time
If someone knows how, please tell me,

Hi,
I made some test here with getting a class reference from an array and using the reference's methods or variables.
Basically arrayEx is a container of type Array and it contains the Person's class instance in it. Num is a number extracted from the Person's instance
Example #1----Strongly typed
Var reference:Person;
Var num:int;
//Assignation
reference=arrayEx[0];-----IT IS SLOW HERE
//Use
num=reference.number --- IT IS FAST HERE
Example #2---Not typed
Var reference:*;
Var num:int;
//Assignation
reference=arrayEx[0]; ---- IT IS FAST HERE
//Use
num=reference.number ---IT IS SLOW HERE
No matter what i change in both code like casting Person on arrayEx, i cant seem to make them work both fast at the same time
If someone knows how, please tell me,

ABAP Class reference in persistent container

Hi all,
Has anyone ever tried to read an abap class reference from a rule container in the rule's function module?
This doesn't seem to work, unless I am doing something wrong...
Here is the scenario:
I have an abap class ZCL_CLASS instantiated in my workflow container. In one of my workflow steps I pass that class object reference to a rule (Function Module based). In the rule function module I use macro swc_get_element to try to get the class object reference. And there it is not getting anything.
I have already tried the following:
- Try to run macro swc_container_to_runtime on the rule container before retrieving the object reference -> doesn't work. The internal table ac_container doesn't even look different before and after having run this macro.
- Try to replace the declaration of include <CNTN01> by <CNTN02> + <CNTN03>. Doesn't change anything either.
When I look at ac_container in debugging it seems my object reference is there but looks a bit strange:
ELEMENT | TAB_INDEX | ELEMLENGTH | TYPE | VALUE
WFIBF_PORTAB | 000011 | 004 | u | SWFTSTRUCT
WFIBF_PORTAB | 000012 | 032 | C | STEP
WFIBF_PORTAB | 000014 | 032 | C | 1CCC1000C
WFIBF_PORTAB | 000015 | 104 | C | <object key>    <class>    CL
Any idea of how I should proceed to retrieve my object reference?
For the moment the workaround I found is to pass the object key to the rule and to reinstantiate the class in the rule function module. Not a very elegant solution...
Thanks in advance and kind regards,
Patrick

Hi Mike,
I understand what you're saying. But the problem is that the swc_get_element macro does not even get me the LPOR value, and therefore I can't call the FIND_BY_LPOR method.
That means I have two solutions:
- Passing the LPOR instead of the object reference to the rule container => Not a very nice solution, for many different reasons.
- Find an alternative to swc_get_element to get the LPOR value.
I had a look at class cl_swf_cnt_container, and it seems it can do the trick for me.
So what I will finally do is:
1. Convert the BOR container into an instance of cl_swf_cnt_container.
DATA: lo_cnt    TYPE REF TO if_swf_cnt_container,
             lt_container TYPE swconttab.
lt_container[] = ac_container[].
TRY.
      CALL METHOD cl_swf_cnt_container=>if_swf_cnt_conversion~create_from_bor_container
        EXPORTING
          values                = lt_container
        RECEIVING
          container           = lo_cnt.
    CATCH cx_swf_utl_obj_create_failed.
ENDTRY.
2. Get my container element.
DATA: lo_myobj TYPE REF TO zcl_class.
CALL METHOD lo_cnt->if_swf_ifs_parameter_container~get
EXPORTING
    name       = 'MyContainerElement'
IMPORTING
    value      = lo_myobj
I didn't take the time to debug that deep in the standard SAP code, but I assume the if_swf_ifs_parameter_container~get re-instantiates my class for me.
Please feel free to comment.
Kind regards,
Patrick

Bad class file error
