Regarding : ClasscastException in MI application

Dear All,
We are migrating the MI2.5 application to NWM7.1. In this phase we are encountering a exception as
Error: 500
Internal Servlet Error:
java.lang.ClassCastException: java.math.BigDecimal
Pls suggest what might be the cause, I am also trying to debug it & find the reason.
The detailed trace is as shown below..
Thanks

Problem with ClassCastException in web application

Hello,
          I'm trying to deploy a web application in WLS 5.1 and I'm getting the
          "dreaded" ClassCastException every time when JSP tries to read a bean
          from the request or session. Under my architecture (actually it's just
          the regular "model 2" ) bean is populated by a servlet, set on the
          request and then retrieved by JSP (servlet forwards to JSP). Everything
          work fine when I register servlets in weblogic.properties, but
          ClassCastException is thrown on any attempt to read from the request if
          the same JSPs and servlets are deployed as web application.
          Has anybody come across the same problem?
          Thanks in advance for help.
          Alexander


Hello,
          This is all well and good as a temporary bug, but it's totally unrealistic for
          the future. Two points:
          * The ClassLoader doesn't need to be discarded, it just needs to be cleared.
          * Other servlet engines seem to be able to handle this.
          Hope it's on its way to resolution!

Has anybody experienced any such problem on weblogic 7.0 sp5?
Thanks & Regards,

Hi Mrutyunjay
This is a common problem often seen in EP 5.0. The only possible solution is to apply SP5 Patch 1 with the latest Hotfix. You can download the same from the Service Marketplace.
For further details refer to SAP Note number 627637.
Please let us know if that fixed your problem.
Warm Regards
Priya.

Regarding Creation of specific Application scenario..

Hii All,
I am having a requirement where i have to create a application in which in FIRST view i m having a dropdown menu,from where i have select one parameter from dropdown menu, say for example there is list of countries in a drop down menu.when i select say India i will get a tabular data say "<b>name of state</b> ","<b>population</b>","<b>male:female ratio</b>" and etc.
and i should get this tabular data corresponding to default country defined.When i will change the country from dropdown menu,I will get all detail(tabular data) corresponding to that country.
and when i click on any item specified in "<b>name of state</b>" i.e one of the column of tabular data,it should display another table(some x, y , z colums) corresponding to that state .
Can anyone help me out on how many bapiwrappers needs to be used for the above application and how will be the structure.
Do i need to use a create, change bapiwrapper for dropdown menu or what??
Thanks in advance
Devendra Kumar Phate.

hello deven,
are you creating an application for MI client or an ABAP
application?
if you already have your data structure available in ABAP,
i don't think that you should re-create one that will cater
to the UI on your client application. if you are using the
MI Tomcat runtime, you can make use of the web control events
like onChange, to retrieve the corresponding data from
data repository using the selected value. you can make use
of XMLHttpRequest and DOM manipulation thru JavaScript;
in this case, there no need for the whole page to be
reloaded; only the delta data would be exchanged. you have
however to create the corresponding handlers in your MI
app that will return these XML elements (e.g. your state
details) that will be inserted into your browser's DOM tree.
hope this gives you an idea.
regards
jo

Please help me regarding Secure RMI Applet Application

Hi Friends..
Currently i use Java Card 2.2.1..
I'm learning about SecureRMIDemo application that shipped with JCDK 2.2.1..
Assume that i've loaded the SecureRMIApplet.cap successfully, and i've created the Secure RMI Client using SmartCardIO..
And then i tried to do any process provided by Purse interface, such as debit, credit, setAccountNumber, etc..
But i got this error message :
java.rmi.RemoteException: Signature mismatch
     at com.sun.javacard.javax.smartcard.rmiclient.CardObjectFactory.throwError(Unknown Source)

     at testRMIClient.SecureRMIClienrt.main(SecureRMIClienrt.java:27)Yes, i know that, that error message required to ensure that the application run in the Security context..
But for me, who just getting started to Java Card Security, it becomes a problem... :(
The message error tells that the Signature is mismatch..
And then how to set this Signature before do any process in the SecureRMI Client application?..
Since there's no way to set the Signature through Purse interface..
Please help me regarding this..
Thanks in advance..

Thanks Shane for your reply..
does it mean i've to send APDU?.. Because in the MySecurityService class code there's method that checks the CLA and INS byte..
Or can i send an APDU Object while we're using the Java Card RMI Application mode?..
Actually, in my opinion, i would say that if we use RMI mode, we don't need APDU Command anymore..
Please correct me if i'm wrong..
Thanks in advance..

Please tell me where am i going wrong. I am running out of time.
I use struts 1.2.9, JDK 5,tomcat 5.5.17. In CandidateListAction class i have hibernate query language statements(HQL)

Take a look at the stack trace, it shows you exactly where the error is coming from:
java.lang.ClassCastException: org.theclass.candidate.view.SearchForm
org.theclass.candidate.view.CandidateListAction.execute(CandidateListAction.java:41)Line 41 in your CandidateListAction.
Probably it is failing on a cast of your action form.
Taking a closer look at your struts-config, you are "chaining" actions.
Your AddCandidateAction uses the candidateForm, and forwards to CandidateListAction.do
Your CandidateListAction uses the searchForm.
That will be the cause of your class cast exception.
<action path="/Add"
name="candidateForm"
type="org.theclass.candidate.view.AddCandidateAction"
validate ="true"
input="/jsp/addcandidate.jsp">
<forward name="success" path="/CandidateList.do"/>
</action>
<action path="/CandidateList"
type="org.theclass.candidate.view.CandidateListAction"
name="searchForm"
scope="request" >
<forward name="failure" path="/jsp/list.jsp"/>
<forward name="success" path="/jsp/candidatelist.jsp"/>
</action>Check out: http://struts.apache.org/1.x/faqs/newbie.html#chaining
Solutions?
- don't chain actions ;-)
- use the same action form for both actions (possible?)
- make the actionForward a "redirect" one. That means a new request, and losing any request parameters/attributes but should prevent this class cast exception.
Hope this helps,

Proble regarding running a java application

hi guys

Query regarding accessing of Webdynpro application from a non-SAP system.

Hi,
I have developed a webdynpro application and I want the users from non-SAP systems to access it from their browser. User will not have to enter the username and password of the SAP system. How will I achieve this? Any suggestions?

Hi Anirban,
you can assign a user in the service of your web dynpro application.
Call transaction SICF and open the service to your web dynpro application.
Within the tab "logon data" you can enter a user/password.
You should not assign a dialoug user.
For productive environment, have a look at all the other options like SSL
and maybe you have to do some more configuration to make it secure!!!
Keep in mind, that all "internet" users are working now with the same SAP user/authorization.
Kind Regards,
Andreas

I have the same problem, when I delete row and after that I use refresh button in internet explorer. What I do is I drag and drop button "removeEntity" and edit it in backing beans adding new bindigs that commit changes and referesh page. Code:
public String commandButton2_action1() {
BindingContainer bindings = getBindings();
OperationBinding operationBinding =
bindings.getOperationBinding("removeEntity");
Object result = operationBinding.execute();
if (!operationBinding.getErrors().isEmpty()) {
return null;
OperationBinding commit1 = bindings.getOperationBinding("Commit");
commit1.execute();
OperationBinding requery = bindings.getOperationBinding("findAllRezerwacja1");
requery.execute();
return null;
In page definition I added "Commit" action and code with methodAction is:
<methodAction id="removeEntity" InstanceName="SessionEJBLocal.dataProvider"
DataControl="SessionEJBLocal" MethodName="removeEntity"
RequiresUpdateModel="true" Action="999">
<NamedData NDName="entity"
NDValue="${bindings.findAllRezerwacja2.currentRow.dataProvider}"
NDType="java.lang.Object"/>
</methodAction>
<action id="Commit" IterBinding="findAllRezerwacja1Iter"
InstanceName="SessionEJBLocal.dataProvider"
DataControl="SessionEJBLocal" RequiresUpdateModel="true"
Action="2"/>
Can sb tell is there is normal that when I delete row in table, and after it I refresh manually by IE page is normal that I get error messages. I this is the same situation using Back in IE. Deleting row that is commited to database works fine, but the problem is with manually refreshing page?
Next question is about using Delete action from node instead of removeEntity, what is the difference? As you can see, I use removeEntitity method. Choosing Delete action instead doesnt works. Why? Rest of the code is the same but instead of dropping method removeEntity I drop Delete action
Sorry for my English, its not my native.
Thank in advance

Regarding MAM 2.5 application

Hi,
I have downloaded MAM 2.5 application from service place.
I have uploaded the MAM25.war taken from 51031176\MBS_MAM_2.5_SR2\MBS_MAM_2.5_SoftwareObjects\Client in the cd to the webconsole. On downloading the app to the device. Only the User view manager is enabled and not order management and other scenarios. Arent they enabled
by default.
I tried to built the MAM25_Eclipse.war from 51031176\MBS_MAM_2.5_SR2\MBS_MAM_2.5_SoftwareObjects\Client_eclipse as MAMApplication.war file and uploaded it to webconsole.
After downloading to the device and on clicked gives page not found error.
Is the application name 'MAMApplication' given in the web console wrong.

Regarding downloading file on application server ?

i am using open data set and close data set to create file on application server.
the program is compiling fine, but when i execute it, it throws a dump saying
DATASET_NOT_OPEN , it says that the file is not open.
when i check value of sy-sub-rc it is 8. no file on server.
i want to create a dynamic file name, like i want to append the sy-cdate to the file name, so that when i schedule my program every day, i will create a new file.
what is the t-code to look at directories on app server. i tried al11, but couldnt find mine..but the basis said they had already created a folder for me there.
- Points will be awarded for inputs.

Hi,
May be you don't have write permission for the corresponding folder on the application server. thats why you could not create file on that folder.so ask you basis people for read/write permission on the that destination folder..
For creating dynamic file , you can use logical file and physical file concept..
for each interface maintain a logical file name in a ztable and ask your basis people to maintain a physical file path on application server for each logical file name.(using FILE Txn).
first get the logical file name from ztable then get corresponding physical path onapplication server using FM 'FILE_GET_NAME' and finally concatenate the sydatun to physical file name...
DATA: l_file_folder TYPE string,
        l_logical_file TYPE fileintern,
CLEAR: file1.
*<b> First get the logical file name from table zabc021</b>
SELECT SINGLE log_file " Actual file location
                     INTO l_logical_file
FROM zabc021
WHERE interface = p_interface
    AND inorout = 'O'. "outbound interface
<b>* Get the physical file name from the logical file name</b>
CALL FUNCTION 'FILE_GET_NAME'
    EXPORTING
CLIENT                        = SY-MANDT
      logical_filename              = l_logical_file
   IMPORTING
     file_name                     = l_file_folder
   EXCEPTIONS
     file_not_found                = 1
     OTHERS                        = 2
IF sy-subrc = 0.
<b>* In actual situation the file name should come from FILE txn</b>
    CONCATENATE l_file_folder
    p_interface '_' sydatum4(2) sydatum6(2) '.DAT' INTO file1.
ELSE.
    CLEAR file1.
    MESSAGE s999 WITH 'No logical file maintained with name ' l_logical_file.
    EXIT.
ENDIF.
now file1 is the file name.
I hope this info is useful to you...

Regarding writing file in application server with ISO8859 characters

Hello Experts,
I have a requirement that i need to write my file which read from the data base in ISO8859 characters in the application server.
Is there any FM or any particular code conver normal data base data to ISO8859 characters ?
Please give me some advise.
Thanks,
Suresh

Hello Suresh,
You DONOT have to do any conversion. You need to use the CODE PAGE addition with your OPEN DATASET stmt.
Can you specify as to which Character Set you need to download? (e.g., Cyrillic, Greek, Polish etc)
You can have a look into the SAP Note 73606 for details.
BR,
Suhas
