Problem of refreshing a tree in web dynpro java

hi all,
I'm facing a problem for refreshing a tree in web dynpro java for SAP HR.
I created a viewset with 2 cells( 1 view for each).
In the 1st view I created a droplistbyindex to select the unit ID and in the 2nd view ( defaut=false) I called a method to populate my tree according to my selection in the 1st view ( method called in wdInit).
When I make the first selection everything is ok.
But when I select another unit ID, the tree is not changed and I know the context is well changed according to my selection.
So I think the method is executed only the first the view is called.
In this case, how can I refresh my tree on real-time?
Thanks for your help
Yimin

May be u can write the code wdDoModify instead.

Problems with Adobe PDF forms in Web Dynpro Java

As of now , I have two major issues in developing Adobe PDF forms in Web Dynpro Java .
1.Text getting wrapped and repeated from the first line :
Any text field that flows to the next page gets wrapped at the end of the page and is again printed on the next page beginning from the first line .
For eg:
If I have 4 lines in a text field that is at the end of the page
1111111111111111111111
2222222222222222222222
3333333333333333333333
4444444444444444444444
and the page holds space for only two lines it prints the lines
1111111111111111111111
2222222222222222222222
in the first page and then proceeds to the next page and prints
1111111111111111111111
2222222222222222222222
rather than printing
3333333333333333333333
4444444444444444444444
2.No way to hide a page at runtime:
It is not possible to hide a page in a PDF form at runtime . If scripting is used , the page turns into a blank page but not hidden .
Any pointers on this????????
Helpful answers will be suitably rewarded with points!!!!

Yes,I am using the versions that you mentioned.
I have a node called MasterData which is the root node for my PDF Form.I have a node called GenData inside this node whose ctx_Appraisal_Type_Num attribute is bound to a hidden TextField in my form.In the docReady event of this TextField, I am writing the following FormCalc script to hide my SubForm whose Id is MngrCmptnc
if(MasterData.GenData.ctx_Appraisal_Type_Num == "2")
then
MasterData.MngrCmptnc.presence = "visible"
MasterData.MngrCmptnc.MngrCmptnc.presence = "visible"
MasterData.StrImp.presence = "visible"
else
MasterData.MngrCmptnc.presence = "hidden"
MasterData.MngrCmptnc.MngrCmptnc.presence = "hidden"
MasterData.StrImp.presence = "hidden"
endif

Problem in connecting JCO destination in web dynpro

HI all,
I was installed sneak preview of Net weaver 6.4,
I want to do some web dynpro (java) programs which connect to back end systems.(R/3 system).
The R/3 system which I want to connect is at remote place, i have connectivity to that R/3 system using VPN connectivity. With this I am not having any problem. Since I am able to connect using User name and password, and able to do some transactions like RZ70, etc.
I developed an application which calls COMPANY_CODE_GET_LIST (BAPI function).
for the above requirement what I did was
(1)I created SLD setting.
(a)Web as Java (I am not having any problem to
Create this.
(b) Web as ABAP.
When i am trying to create
This, there are some steps like i need to go to SAP log in and I need to run the transaction RZ70. For this i need to create an enter in visual administrator>JCO RFC Provider>runtime-->Bundles i need to create an entry for RFC destination as well as Repository.
under RFC destination there are some fields which i need to enter those are (a)Program ID as mySLD (b) Gateway Host as 10.10.10.125 (c)Gateway service as sapgw00 (d)Number of processes as 1
Under Repository (a) Application server host 10.10.10.125 (b)system number as 00 (c)Client number as 100 (d)Language as en (e)user as ABCD (f)password as 1234
I haven't choused the check boxes Local bundle and Unicode and pressed the set button. So like this i created the RFC destinations. under the properties tab there is a property called RFC_DEFAULT_DESTINATION by default it was false so i made it as true. .
I also went to SLD Data Supplier,under Runtime tab , HTTP Settings , I mentioned
(a)Host: pava-vis75
(b) Port: 50000
(c) user: administrator
(d) password: abcd1234
RFC Settings, I mentioned as
(a)Gateway Host: 10.10.10.125 (which is SAP R/3 system)
(b)Gateway Service/Host: sapgw00
CIM Client Generation settings, as
(a)Host: pava-vis75
(b)Port (http/https):50000
(c) user: administrator
(d) Password : abcd1234
I tested the CIMClient Test by click the the button. I got the successful message.
Then I came back to HTTP settings and clicked the button with tilted arrow mark [This triggers data transfer to system landscape directory], for this also I got a successfully message.[data transferred successfully]
Next I been to SAPLOGON and went to RFC Destinations by using sm59 transaction. There under TCP/IP connections i been to SLD_NUC , opened this by double clicking that and under Technical settings for Program ID I had given the ID which I created at visual administrator [JCO RFC Provider] which is mySLD , under gateway options for Gateway Host as 10.10.10.125and Gateway service as sapgw00 then i tested the connection, it was also successfully.
Then I opened the SLDAPICUST and i created a new entry for maintaining the SLD Access Data by giving some couple of entries as
(a)Alias: vissldtest
(b)Host Name: pava-vis75
(c)Port: 50000
(d) user: administrator
(e) password: abcd1234
Then saved it.
Next I created sapmsUV0 3600/tcp entry at
WINDOWS\system32\drivers\etc\services file, and also there are some required entries which are already existing those are sapgw00 3300/tcp to sapgw99 3399/tcp , another entry starts from sapdp00s 4700/tcp to sapdp99s 4799/tcp , next entry starts from sapgw00s 4800/tcp to sapgw99s 4899/tcp and sapmsJ2E 3601/tcp .
I restarted the system, as well as server.
Now my problem is when I was trying to create JCO destination at web dynpro content administrator. For that I navigated as create JCO Destination Deployed Contentlocal-local/CompanyCodeGetList-Applications CompanyCodeGetList
I Choosed the JCO Connections tab- there are 2 entries those are
(1) COMPANY_CODE_MODEL
(2) COMPANY_CODE_RFC_METADATA
So I started creating connection for COMPANY_CODE_RFC_METADATA.
First one is
General data Name : COMPANY_CODE_RFC_METADATA
Client : 100
I didnt changed any default JCo pool configuration.
J2EE Cluster
There is a check box called Use Local J2EE engine J2E on pava-vis75 so I choosed that.
Connection Type
Dictionary Meta Data and application Data
I choosed the first one.
Then
Msg. Server Connection
Security
After these, I tried to test the connection by clicking the Test Connection.
It is saying the error as
First time
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=v011 GROUP=DEFAULT R3NAME=UV0 MSSERV=sapmsUV0 PCS=1 ERROR service 'sapmsUVO' unknown TIME Fri Jul 01 07:20:41 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 COUNTER 1
second time
com.sap.mw.jco.JCO$Exception: (102) RFC_ERROR_COMMUNICATION: Connect to message server host failed Connect_PM TYPE=B MSHOST=v011 GROUP=DEFAULT R3NAME=UV0 MSSERV=sapmsUV0 PCS=1 ERROR service '?' unknown TIME Fri Jul 01 07:20:41 2006 RELEASE 640 COMPONENT NI (network interface) VERSION 37 RC -3 COUNTER 1
Can any body please help me to solve this problem.
From past 1 week on wards I have been trying to resolve this. But in vain.

It does not necessarily mean that you have to change that parameter. I read that blog as I had a similar problem, and after reading it and understanding the reasons and possible causes for the error, I found that my particular problem was that I was using "PUBLIC" as the logon group in my JCO destinations, but such a group does NOT exist at my backend. I went to transaction SMLG, had a look at Logon Groups, noted that there were none other than SPACE, figured out that I had to include that information in SLD (Web AS ABAP tech. system --> Message Server --> Logon Groups), put it there. Voilá. It works.
Edit: That SPACE logon group is the one I had to use at JCO destinations. Sorry I forgot to mention that one...

Deploying problem of web dynpro java application

Hi,
I have a web dynpro java application with no problem about deploying.
I copied this application with another name.
I tryed new application to deploy but sdm aborted with error.

Hi,
Since the exception says "Are all referenced components deployed and available on the engine?"
Check wether any DC is used as a used DC in the webdynpro component which you are deploying.
If any used DC is available try to deploy that DC in the server and then deploy ur webdynpro application.
If all reference DC's are avialable in server, still if you get this error try to rename the component and reload+rebuild the project and deploy it.
Hope this helps you...

Problem when generating an non-interactive form in Web Dynpro java.

Hi,
I'm trying to create a PDFDocument using a creation context in java. Everything works fine when the Interactive property of the creation context is set to true. When I change it to false however, the Web dynpro application hangs and eventually throws the following exception:
java.net.SocketTimeoutException: Read timed out
   at java.net.SocketInputStream.socketRead0(Native Method)
   at java.net.SocketInputStream.read(SocketInputStream.java:129)
   at java.io.BufferedInputStream.fill(BufferedInputStream.java:183)
   at java.io.BufferedInputStream.read(BufferedInputStream.java:201)
   at com.sap.engine.services.webservices.jaxm.soap.HTTPSocket.readLine(HTTPSocket.java:806)
I'm wondering why this exception occurs when i'm generating a non interactive form and never appears when i'm generating a form with the Interactive property set to true.
Any ideas?
Edited by: Arjan Nieuwenhuizen on Feb 25, 2008 3:24 PM

Yeah I know changing the form properties will solve my problem, but since i'm developing a training for Interactive Forms in Web Dynpro Java, I wanted to figure out why the (static / non-interactive) combination didn't work, turned out to be a template problem, which i still didn't figure out, except the fact that having flowed content on your template is not the problem.
My ideas about your question:
When we have the layout of an Interactive Form, its clear if it's meant to be static or dynamic, we don't know however, if it's interactive or non-interactive.
I don't think we can judge a layout to have an Interactive or non-interactive purpose, can depend on the situation in which the same form is shown/used:
- One moment it can be interactive, e.g. user is filling in the form, can enter data etc.
- Next moment it can be non-interactive, e.g. form is shown to another user.
So it's more the scenario/situation that determines if the form is interactive or non-interactive.

Clear/refresh(F5) fields in web dynpro application view

How to clear or refresh(F5) fields in web dynpro application abap while redirecting to another view? I have tried using "context_node->invalidate()" but it's not working for all the fields, some are getting initialised and some not. Is there any other method to refresh all the fields in the view all at once. Please guide.

Hi,
For the Context node( to which the drop down is bound) create a supply function as shown below:
Now populate the drop down in supply function method instead of WDDOINIT method.
Go to methods tab and write the below code in supply function method:
DATA lo_nd_drop TYPE REF TO if_wd_context_node.
    DATA lt_drop TYPE wd_this->elements_drop.
    DATA ls_drop TYPE wd_this->element_drop.
*Fill Drop down
    ls_drop-val = 'ABC'.
    APPEND ls_drop to lt_drop.
    ls_drop-val = 'DEF'.
    APPEND ls_drop to lt_drop.
* bind all the elements
   node->bind_table(
     new_items            = lt_drop
     set_initial_elements = abap_true ).
Now once you call invalidate( ) the drop down will automatically be initialized( since the supply function will be called again) And you don't have to write the code again to populate the drop down.
hope it's clear now.

Kiran

Problem in completing the TASK when using Web Dynpro Java and BPM

Hi,
I am using Web Dynpro Java and BPM.
i see my Web Dynpro View when i run the process.
Just that the task is not completing.
when i click on the Web Dynpro button to signal the completion of the event, nothing happens.
i have appropriately created events in both Component controller and Interface Controller and used the same in creating the Task.
a method in Component controller fires the event and a button click in the view calls this method.
i have successfully completed Donka Dimitrova's "SAP Netweaver Business Process Management-End-to-End Process Implementation Sample " but when i tried my own with slight modifications, it is not working !!!

Hi Amol,
The way you described the things, I dont see any problems. Just to make sure that you are triggering the right event that you mapped as completion event for the task, try to cross check once again and see if the correct event is getting triggered. Also try to put some messages for debugging to see till where the control goes.

Hello John,
Thanks for the link. We have performed the steps in this blog:
1) Create DC Project "External Library" with name js/jars:
- Add *.jars in folder Libraries.[Screenshot Libraries|http://img846.imageshack.us/img846/8395/jsjars.jpg]
- Add archives (*.jar) to public part with name ExternalLib. Which option to choose?
a- Provides an API for developing/compiling other DCs (Option chosen)
b- Can be packaged into other build results (eg SDAs)
- Development Component -> Build
Step 1 is OK.
2) Create "J2EE Server Component / Library" DC with name js/lib:
- Add Used DC -> public part project ExternalLibrary -> "ExternalLib"
- Specify both build time and run-time dependency here and strong.
- Generated SDA file in <var>gen/default/deploy</var> How do we check that it contains <var>js.jar</var>?
- folder gen/default/plublic/defLib/lib/java then you meet *.jars files again. is OK.
- Development Component -> Deploy.
- Go to Visual Administrator. We found the library js/lib, but has no associated *. jar. It is the problem.[Screenshot Visual Administrator|http://img542.imageshack.us/img542/5537/visualadminlib.jpg]
3) Create "WebDynpro" DC with name pdf_jasper
- Add used DC (defLib) to WebDynpro DC with option "Build time".
- WebDynpro References -> Library references --> add <var>jslib
- Deploy
- Run error: java.lang.NoClassDefFoundError: net/sf/jasperreports/engine/JRDataSource

Problem: Changing Language for Web Dynpro Java within NW Portal (i18n)

Hi Experts out there,
I hope all you had a nice Christmas and a big New Years Eve :)!!!
i got a challenge for you about WD Java and internationalization (i18n)
Here is the scenario:
We are using a SAP NetWeaver Portal 7.0 and my task is to implement some smaller Web Dynpro Applications.
These Applications must be i18n conform, so i just created (according to the corresponding WD Java tutorial) some ".xlf" files.
Okay...Everything is working fine. The user can log at the portal and the application is displayed in his language, which is "english" or "german". (the application is just a simple form)
So far so good...Now here comes the point where it's getting tricky...
When the user wants to change his assigned language (of the portal user) he can use the "personalize" button in the Masthead (-> change portal language). All the portal content should now be displayed in his new chosen language.
For example the user is logged into the portal with "german" as portal language and now changes his languages settings into "english". After this everything in the portal (navigation, portal iViews ) is displayed in the changed language (from english into german) ...
BUT: my Web Dynpro Java Application stays as the original languages setting was. That means the whole portal is now english, but my WD Java Appl. stays german .
Only if the user logs of and logs in again, the WD Java Appl. is displayed in the corresponding portal language...
VERY Strange?!?!
Can anybody give me a hint how to solve this problem?
I guess i have to re-initiate the Web Dynpro Application some how ...(like killing the application and restarting it ...) but is just a "weak guess"...
Any Help / Hint is more than welcome !!!
Cheers
Stefan

Hi Stefan,
This correct see SAP Note [947081|https://service.sap.com/sap/support/notes/947081]
If the locale for the Web Dynpro iView is changed in the portal (through portal personalization), this is not reflected in the running login session. The user needs to logoff and login again, in order to see the locale change in the Web Dynpro iView.

Leo

Date format problem in web dynpro java

Currently, the date format that gets displayed in our webdynpro java application is MMDDYYYY...i am assuming this is because the web dynpro application has language resource set to en_US as its Current locale in the web dynpro deployed content section. Howver i want it to display as DDMMYYYY. I have changed the default properties in visual admin for web dynpro from en to en_GB however this has no impact what so ever as the current locale is always set to en_US even after the change so am wondering this property is hidden some where else. Now the web dynpro i am talking about is a adobe portal application. Could you give me any pointers as to where else i can look for or how i can change the current locale properly ??
Regards
Kal

The date format in the Web Dynpro Java Application depends upon locale. At runtime WDJ will do the following process to get the current locale for the date format to be determined.
1. First the WDJ Application will check for the locale set for the user in UME.
2. If there is no default locale in UME, then the it will check for the locale in the in the browser which in most cases by default is en-us.
3. If not, then it will check for the sap.systemLocale in the Propertysheet default of Visual Admin
4. If there no locale specified in Visual Admin, itu2019s taken from the WAS JVM

Portal Eventing between Web DynPro Java iView and non-Web DynPro iView

Dear Experts,
I have 1 Web DynPro Java iView and 1 non-Web DynPro (using JSPDynPage and JSP) iView, both attached to a page. When Web DynPro Java iView fire a portal raise event, the portal iView did not execute the javascript function tied to the event subscribed.
Here is the code snippet which reside in the Web DynPro Java iView that is used to fire the event
String param = "test";
WPortalEventing.fire("urn:com.company.Test1", "TestEvent", param);
This the code snippet that is in the jsp page
function notifyTest(param)
     // Code to print param value here
EPCM.subscribeEvent("urn:com.company.Test1", "TestEvent", notifyTest);
Note:
1. When Web DynPro Java iView fire the portal event the entire page is refreshed, including the non-WDP iView.
2. When EPCM is replaced with window.top.EPCM, the page is refreshed, it is totally hanged with progress bar.
Can anyone help to solve this problem?

hi
Please write the below code snippet in ur jsp for notifyTestjavascriptfunction
function notifyTest( eventObj ) {
     eventParameter=eventObj.dataObject;
     // code to print the parameter "eventParameter"

Web Dynpro Java : Failed to get deployable object part info for component

Currently we have a web dynpro java project which connects to the ABAP backend with Web Services. Everything seems fine, and when we transport to the production server via NWDI, we have the following error. Everytime we try to access the application , the error is occurred.
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to get deployable object part info for component com.sie.attachmentcomp.AttachmentComp
 at com.sap.tc.webdynpro.clientserver.cal.ClientComponent.getComponentDeploymentDescription(ClientComponent.java:784)

 at com.sap.tc.webdynpro.progmodel.components.ComponentUsage.createComponent(ComponentUsage.java:116)
It is working properly in our development , and testing environment. Only production has this error. And one weird thing is that this particular error occurred only sometimes to some user. For example; I could not access to the application with this error yesterday but my friend can access. Today, I can access in the morning but my friend cannot. For another friend , Yesterday he can access by using IE but not by Firefox. But today Firefox is fine but not with IE. It seems crazy.
For more information, in our J2EE engine for the production server, we have 3 server nodes (clusters). And we are not sure it is the source of the problem. Is there any solution , and any way to know from the application that we are on which server?
We also go and check from the Content Administrator in Web Dynpro Console. Under our project name, in the list of Components, sometimes we can see AttachmentComp but sometimes not.
Please help us as our project is about to go-live next week.
Thanks,
Yu
