No access via webinterface possible

hey,
i'm working with oracle 11g for a few weeks now. But now i have a problem and need some help.
Yesterday, i deleted the database and created a new one. afterwards i configured the listener. during the listener configuration i recieved a port error (standard port is used by another application). i told oracle to go on because i thought the error ocured because of another application in the background, but i was wrong.
now i am not able to access the oracle webinterface. but i'm able to access via sql developer.
who can help me to get webaccess again?
cu and thx

Web-UI error message "Access via 'NULL' object reference not possible"

I need some help, I'm not a Basis person but I need to get this connection problem resolve.
This problem is in our DEV ICWeb system. After logging in to Web-UI, I got a error message "Access via 'NULL' object reference not possible". We have 3 clients (100, 220, & 310) in DEV and all 3 clients are giving me the same error message.
From the help.sap.com, I found this topic http://help.sap.com/saphelp_nwes70/helpdata/en/84/43f0d786304e19a652a8f80909a8ec/content.htm
but in the document it asked to go to SM59 to check the ESH_APPL_WS_TEMPLATEENGINE destination. But we don't have that destination setup in all our systems.
Here is the complete error message:

Thanks Rama,
Acutally i accidentally commented the lo_nd_student = wd_context ....etc
this line was commented .
i have one small requirement to fetch data from local customised table and fill the same to internal table and bind that to table node.
my table node is student having attributes as name , city and number , all are of type strings.
now i created one custom table zstudent having ID - char of length 10,
name of type string
city of type string
num of type string
i have inserted records
but when i use select query to fill data from this zstudent to my internal table of type lt_student type wd_this->elements_student ,
im getting same above error.

hi ,
The attribute M_HANDLER is an attirbute of component controller (as told by your post) and so you cannot access it as you have done it.
You will have to access it as .
WD_COMP_CONTROLLER->M_HANDLER->GET_RANGE_TABLE_OF_SEL_FIELD(I_ID = 'S_CARR_ID' ).
Try doing it.
Or else , if you have created a similar attribute in your view itself , then it is "INITIAL" and hence you are getting the dump.
You will have to assign the view attribute "M_HANDLER" with the value of your component controller attribute "M_HANDLER" ,because all the initializations are done in WDDOINIT of comp controller and on component controller atribute "M_HANDLER".
Thanks,
aditya.

Hi,
 Structure of the CONTEXT in the VIEW::

IC WEBCLIENT: Access via 'NULL' object reference not possible

Hi,
Iam working in ABAP, and learning CRM ABAP on CRM5.0 IDES Demo system I was trying to create a new WebIC by copying one view from CRM_IC to ZCRM_IC bsp application. Following are the steps I following according to Cook book documentation.
1. I copied BuPaDisplayCustomer view and controller from CRM_IC to ZCRM_IC from
    BSP_WD_WORKBENCH by selecting CRM_IC and runtime profile = 'DEFAULT'.
2. Created a runtime profile from SPRO->CRM->IC Webclient->Customer specific modifications->Define
   runtime profile.
3. Copied the 'DEFAULT' runtime profile to my new profile 'Z_COOKBOOK'. Assign 'ZCRM_IC' by
   clicking on 'Controller and substitues'.
   BSP       Replaced Controller         BSP                 ReplacmentController
   CRM_IC BuPaMoreContactView    Z_CRM_IC         BuPaMoreContactView
4. Define IC Webclient profile:
    SPRO->CRM->IC Webclient->Define IC Webclient profile->Copy the DEFAULT profile and assign it to
    'Z_COOKBOOK',
5. Assigned the Webclient profile to the user from t-code 'PPOMW'. Selected 'USER' from the
    existing 'Position' and Goto->Detail object->Enhanced obj descrption.Selected IC webclient from the
   list and created Infotype assigned Webclient profile 'Z_COOKBOOK'.
6. Execute the ZCRM_IC from SE80 by rightclick and Test. Here is my problem,Iam receiving the
   following error in the webpage.
     The following error text was processed in the system CR7 :
           Access via 'NULL' object reference not possible.
    The error occurred on the application server CR7_01 and in the work process 0 .
    The termination type was: RABAX_STATE

      Function: HTTP_DISPATCH_REQUEST of program SAPLHTTP_RUNTIME
      Module: %_HTTP_START of program SAPMHTTP
I check the CRM services and all are active, using IE8 web browser. I just copied the view and controller
from CRM_IC into Custom BSP application i.e., ZCRM_IC.
Above error is occuring even If i run the standard CRM_IC BSP application and select one simple view.
from SE80.
Not sure whether any additional configuration or any special roles to be assigned to the Webclient profile.
Thanks,
Venn.

WebDynpro Abap MSS: Access via "NULL" object reference not possible

hi,
My customer send me the following link to Appraisal Documents (Manager) MSS

http://a.imageshack.us/img225/4008/mss4.jpg (Appraisal Documents (Manager) MSS run succesful)
Link that also run by the SICF in my customer is correct.
But when I run in my SAP System see the following error

Hello
The most important information is (again) missing: which object reference is initial ("NULL")?
The ABAP dump will tell you.
Below I show an example how this can happen (and be avoided):
LOOP AT lt_accountings INTO ls_accounting.
lo_po_account ?= ls_accounting-accounting.
ENDLOOP.
" QUESTION: Are you sure that lo_po_account hold an instance ???
" If LO_PO_ACCOUNT is empty the following statement will give you the dump.
ls_mepoaccounting = lo_po_account->get_data( ).
" And that is how to avoid this (at least the dump. Whether your logic is still ok is another matter...)
CHECK ( lo_po_account IS BOUND ).
ls_mepoaccounting = lo_po_account->get_data( ).
Regards
Uwe

Getting error on Portal : Access via 'NULL' object reference not possible

hi friends,
While executing a bapi,I am getting this error : Access via 'NULL' object reference not possible., error key: RFC_ERROR_SYSTEM_FAILURE
I am calling a bapi with only one required parameter from Portal as per the design of the bapi and the bapi itself is calling some other functions internally.
I a using ECC 5.00 i,e. EA-HR 5.00. On SDN it is suggested to Apply OSS Note 1018036. But it is applicable to EA-HR 6.00 and subsequent releases,I guess.
Need your suggestions and also need to know if the above Note can be applied to EA-HR 5.00.
P.S: Points would be assigned, thanks is advance.

Hello Vaish & Ankit,
Can you check what is the dump occurred in transaction ST22?
I hope you guys are working with HR data. So, i think some object is not passed(internally) correctly in RFC.
Please debug the RFC by keeping the breakpoint from webdynpro application, then you will come to know what is not passed when we execute the RFC from R/3.

Access via NULL reference object not possible

Hi friends,
I have created an wda application which uses the table popin to display data.
So that i have created a view with two of the fields as link to action UI element.
In the Events/Actions of the link to action element i implemented the following logic.
data wd_table_cell_editor type ref to cl_Wd_view_element.
data wd_table_column type ref to cl_wd_table_column.
data wd_popin type ref to cl_wd_table_popin.
data id type string.
 wd_table_cell_editor ?= wd_this->m_view->get_element( id ).
wd_table_column ?= wd_table_cell_editor->get__parent( ).
wd_popin = wd_table_column->get_popin( ).
context_element->set_attribute( name = 'SELECTED_POPIN' value =
wd_popin->id ).
So when i click on the link to action in the table column of the field am getting the following error
Access via NULL reference object not possible.
While debugging i have noticed that this error was coming at the below step of the code.
wd_table_cell_editor ?= wd_this->m_view->get_element( id )
in the m_view->get_element( id ) does not contan any value , its showing as table , as null value cannnot be assigned may be its throwing the above error.
But i didnt understand why the view is not getting UI element id ....
Can one please suggest me where might be the wrong....
Regards
Sireesha.

Hi nithya,
Could you please calrify the doubts for the following q's.
1. As u said in the above post, i have changed the code to the below.
 data: lr_table type ref to cl_wd_table,
lr_table_col type ref to cl_wd_table_column.
lr_table ?= wd_this->m_view->get_element( 'TABLE' ).
lr_table_col = lr_table->get_column( ID = 'TABLE_CONNECTID' ).
wd_popin = lr_table_col->get_popin( ).
(At the above step which is in bold , eventhough there is value in lr_table_col->get_popin , its not assigning a value to the wd_popin, throwing same error NULL etc.,)
context_element->set_attribute( name = 'SELECTED_POPIN' value =
wd_popin->id ).
2. Before changing the code suggested by u, the follwoing was the code from standard example.Its working fine in the application wdr_test_table.I have debugged the code.The value is getting assigned into wd_table_cell_editor.
The same thing i have done but its failing to assign the value. thats y its throwing null reference error. Here i have a confusion how its assigning a value and y not in the z application.am giving the code below which is in standard and my application.Please clarify these.
data wd_table_cell_editor type ref to cl_Wd_view_element.
data wd_table_column type ref to cl_wd_table_column.
data wd_popin type ref to cl_wd_table_popin.
wd_table_cell_editor ?= wd_this->m_view->get_element( id ).
( Note : wd_this->m_view->get_element contains value but not assigning it to the wd_table_cell_editor and same code in the standard behaving correctly like assigning the view value to the cell editor. Y this behavior, please advice me)
wd_table_column ?= wd_table_cell_editor->get__parent( ).
wd_popin = wd_table_column->get_popin( ).
context_element->set_attribute( name = 'SELECTED_POPIN' value = wd_popin->id )

Access via null obj ref not possible error

Hi
I am using an assistance class and have specified it in the component...
i am getting the error Access via null obj ref not possible at following point in the code..
temp = wd_assist->IF_WD_COMPONENT_ASSISTANCE~GET_TEXT( key = '001' ).
i do not think we need to instantiate a assistance class ( or am i missing something ?/ )

Hi,
After reading all these posts and i have done a small test , it is working for me as the other posts already confirmed. I am not sure why it is not working for you the way you described and it is working for all others.
I hope that you are not executing this code from used component->view referring the WD_ASSIST where in the wd_assist reference is not passed.
moreover to make sure that the error is from this code you can code a if else construct.
if wd_assist is bound.
" get the text element.
endif.
If the above code is working then i suspect that the text element is not active .
Success.

Is it possible to have a VI "run when opened" when accessed via Internet Explorer?

I am trying to get a remote panel application to "run when opened" when is accessed via Internet explorer. I have multiple remote panel licenses on the server and the VI is Re-entrant. The application works well except for this issue. Having the VI "Run When Opened" via IE is very important to the user. As is, when IE opens, the user must click on the panel image once to get the VI's attention and then again on the start arrow to run the program. Is there any way around this or a way to simplify the process?
Thanks.
Solved!
Go to Solution.

This is actually the intended operation of remote front panels, however, we can simplify the operation to meet closer with what your customer wants. Basically, if you were to always have your program run in somewhat of an idle state, you can use the Application Control>>Property node for 'RemotePanel.ConnToClients' property to determine when a user is connected and run the proccess of the program as soon as a connection is detected. When no connection is detected you could have the program run in an idle state. The attached screenshot shows a general way to do this. Have a good evening!

Getting error "Access via null" when running the web dynpro application

Hi experts,
I am getting the below error while executing my web dynpro application
500 SAP Internal Server Error
ERROR: Access via 'NULL' object reference not possible. (termination: RABAX_STATE)
I am getting the error only when I am calling a method create manufacturer from my web dynpro program. If i comment this code my application works fine
CALL METHOD wd_this->mo_ch_instance->create_manufacturer
EXPORTING
    gi_manufacturer = ls_manufacturer
IMPORTING
    lv_message      = lv_status
i have created a attribute mo_ch_instance of type YSRM70CL_CH_SW_MD where YSRM70CL_CH_SW_MD is the class which has the create_manufacturer method that i am using in my code.
Kindly let me know whats the issue.
Regards,
Vinod

Hi,
if   wd_this->mo_ch_instance is not initial.
CALL METHOD wd_this->mo_ch_instance->create_manufacturer
EXPORTING
gi_manufacturer = ls_manufacturer
IMPORTING
lv_message = lv_status
endif.
Check wether you have created the object for that class r not.

Lekha.
