Using jxl.jar in Java Web Dynpro using NWDS 7.0.09

Hi ,
I have a requiremnt to read excel file and I am trying to use jxl.jar for the same but I am facing issues which using it as External Library DC.During executing,I am getting NoClassFoundException.Please help .

Hi
Only one thing u missed that instead of Publishing as file you have to publish it as archive.
Further u can check
1. Publish as archive.for both compilation and assembly.
2. Each changes require Build of the external library dc also.Build it and then run

How to use EVS with different data in each row, in a Java Web Dynpro table?

Hi all,
I am using EVS in a column of java web dynpro table.
Let's say the name, and context attribute, of this column is column1.
It's filled dynamically using an RFC, that uses as input parameter the value of another column, and related context attribute, from the same table (Let's call it column2). Obviously, from the same row. So, in other words: the values of the EVS in column1 of row1, are dependent of the value of column2 of row1. And the values of the EVS in column1 of row2, are dependent of the value of column2 of row2. And so on... Hope i could explain myself ok.
The code I'm using works great for filling the EVS dynamically:
IWDAttributeInfo attrInfo = wdContext.nodeDetail().getNodeInfo().getAttribute(nodeElement.COLUMN1);
ISimpleTypeModifiable siType = attrInfo.getModifiableSimpleType();
IModifiableSimpleValueSet<String> value = siType.getSVServices().getModifiableSimpleValueSet();
value.clear();
if(this.initRFC_Input(nodeElement.getColumn2())){
     for (int i = 0; i < wdContext.nodeRFCresult().size(); i++){
          value.put(wdContext.nodeRFCresult().getRFCresultElementAt(i).getLgort()
             , wdContext.nodeRFCresult().getRFCresultElementAt(i).getLgobe());
In this code, nodeElement is the context row of the table that is passed dynamically to the method when the value of colum2 is changed.
HOWEVER, the problem I'm having is that after executing this code, EACH NEW ROW that is added to the table has by default the same values as the first row, in the column1 EVS. And, for example, if I refresh the values of the column1 EVS in row 2, all EVS values in the other rows are also refreshed with the same values as the ones of EVS in row 2.
How can I make sure each row EVS has its own set of independent values, so they don't mess with each other?
Hope you guys can help me. And please, let me know if I didn't explain myself correctly!
Thanks!

I just did as you said (I think), but it's still having the same behaviour as before (same data for all EVS in the table).
Here´s what I did:
I
In node "Detail" (cardinality 0...n, singleton set to true), which is binded to the table, I created a child node named "Column1Values" wth cardinality 1...1 and singleton set to false.
"Column1Values" node has an attribute called "column1", of type String.
I did the binding between attribute "column1" and the column1 inputfield celleditor in the table.
I created an event called Column2Changed and binded it to the column2 celleditor of the table. I added a parameter called nodeElement of type IPrivateCompView.IDetailElement to this event, and mapped it to the column2 editor in the table so that I can dynamically get the nodeElement that is being affected.
I added the following code to the onActionColumn2Changed(wdEvent, nodeElement) method that gets created in the view:
IWDAttributeInfo attrInfo = nodeElement.nodeColumn1Values().getNodeInfo().getAttribute("column1");
ISimpleTypeModifiable siType = attrInfo.getModifiableSimpleType();
IModifiableSimpleValueSet<String> value = siType.getSVServices().getModifiableSimpleValueSet();
if(this.initRFC_Input(nodeElement.getColumn2())){
     for(int i =0; i < wdContext.nodeRFCresults().size(); i++){
          value.put(wdContext.nodeRFCresults().getRFCresultsElementAt(i).getId(),
                              wdContext.nodeRFCresults().getRFCresultsElementAt(i).getDesc());
And with this, I still get the original problem... When the EVS of one row is updated, ALL other EVS of the table get also updated with the same values.
What am I missing? Sorry Govardan, I bet I'm not seeing something really obvious... hopefully you can point me in the right direction.
Thanks!

What is the right way to display a table in Java web dynpro using a node.

Hi experts,
I am trying to show a node of cardinality 0...n as a table in an adobe form in Java web dynpro. But its not showing it properly. Can anybody please tell me what is the right way to display a table on adobe form using a node of cardinality 0...n or 1...n in Java Webdynpro. In ABAP webdynpro, we can drag and drop a node of cardianlity 0...n or 1...n to show as a table and it works fine. Is the same possible in Java webdynpro also. Please help.
Thanks and Regards.

Please refer to my post.. you will get the answer
Dynamic Table - same data repeating in all rows
Special care should be taken in designing the context for table attribute.
The attribute type singletone also plays a important role. I have this doubt from the beginning when you have reported this problem for the first time but finally you marked it as solved so i thought there might be some other issues but again when you reported that again i did some analysis.
Now coming to final solution :
For designing a table in adobe interactive form you have consider following
You have to design the view context upto three level, I am explaining you the properties
PDFDataSource (Parent Level1) - Cardinality 1:1 - Signetone -True - This is assigned to datasource
TableList (Parent Level2) - Cardinality (1:1) - Signetone -True
TableWrapper(Parent Level3) - Cardinality (0:n) - Signetone -True
TableData (Parent Level4) - Cardinality (0:1) - Signetone - false (This is the main point)
Then under TableData value node, you have to put all your table attributes.
This Value Node name can be anything but hierarchy should be same as I have mentioned above.
Please try out these steps and get back to me if you have any doubt.

Using Java Web Dynpro iViews to integrate with SAP MDM

Hi,
I have already SAP MDM 5.5 supplied iViews with Enterprise Portal.
These include itemDetail iView, ResultSet iView, PicklistSearch, Hiearchy Search.
Now, I am integrating Java Web Dynpro iViews with SAP MDM.
When adding the fields using object of ResultSetDefinition Class, should we use MDM Table Name or MDM Table Name Code/MDM Field Name or MDM Field Code?
I think we should use the CODE as the name as it does not contains any space while working with Java API.
Regards
Kaushik Banerjee

Hi Kaushik ,
Yes you should use the Field and Table CODE when integrating MDM with any other system using API either Java, Abap or Com api.
Actually this is one of the main use of the code in MDM .In API.
Hope It Helped
Thanks & Regards

Nwdi-managed access of pcd-objects from java web dynpro

Hi,
im am trying to access portal pcd-objects from a java web dynpro component (namely getting and setting personalized iview properties). for locally managed web dynpro components this works fine with the code below.
when i try the same with a nwdi managed web dynpro component i run into problems regarding references to used dcs. for instance, i need to reference used dc SAP_JTECHS/tc/epbc/pcm/adminapi/java because the build needs tcepbcpcmadminapijava.jar which is inside the mentioned dc. but access permissions of this dc don't allow the dependency. when i try to "add used dc ..." in nwds i get the error message: illegal dependency: access list does not allow use of ...
has someone any solution for this problem? are there other ways of accessing pcd-objects from java web dynpro (nwdi managed!)?

To access the PCD objects the code you used looks ok for me but your main issues is related to the dc access permissions. This thread discussed about the similar issue. Please review this below thread.

How to consume the Abap web service in Java web-dynpro

Hi Everyone,
I want to consume ABAP web service in java web dynpro.
so when i tried to create model in java web-dynpro, it gave me an error message saying "Invalid WSDL or WSDL not found".
i think this error message is because, to access the WSDL of abap web-service, we need username and password, but the dialog box in java web-dynpro is not programmed to take username and password from us and send it to the server to get the WSDL.
i came to this conclusion because i was able to successfully test my abap web-service in java portal. the java portal asked me the username and password to open the WSDL.
So, please help me to consume the abap web service in java web-dynpro.
Thanks in advance
Regards
Vikas

Hi Vikas ,
while creating a model in web-dynpro try to use the "import web service model" option and if you are using local server choose the local server option so that you can get the available web services which are in server, select one among them and continue you process.I think this is the some what easy way .
If you want use the URL for wsdl better to once test the available service in server and copy that WSDL URL and paste over WSDL textbox.
I think this is pretty help ful to you

Unable to download file from FileDownload UI Element - Java Web Dynpro

Hello Experts,
I am facing a strange issue.Scenario is:
I created an java web Dynpro application (Please note that it is just a standalone WD app, not integrated in portal) with just one FileUpload UI Element ,one FileDownload UI element and one button (for triggering an action).
I browse a file (e.g. text,pdf,doc etc.) and click on button. It uploads the file and when I click on download, there are two cases:
1) Simply click on download does not downloads the file and shows error: "Unable to download <file name> from <server name>. Unable to open this Internet site. The requested site is either unavailable or cannot be found. Please try again later." Though it is opening the file,showing the content.
2) I opened that portal URL in a new tab in same session and logged in with a portal user. Now if I click on download link of same WD app opened in different tab of same session, it downloads the file without any error.
I am using portal 7.0
Can somebody point what's going wrong with case 1?
Helpful pointers will be appreciated.
Thanks,
Kirtiman

Hi Sid,
I did not gave any authentication of WD app as it is anonymous app. There is no parameter set in application properties.
As I run the app, it is showing the initial screen with UI elemtns and till upload works fine,.It has to be an anonymous app, so cannot ask for credential from user.
Thanks

Convert JAVA Web Dynpro to ABAP Web Dynpro application

Hi,
I was hoping someone could tell me if there is a way to port a JAVA Web Dynpro application to ABAP Web Dynpro. We have some JAVA WD apps that would now make more sense to have running on our ABAP system so we would like to convert them to ABAP WD apps.
I know the theory is that WD is metadata/XML based so it should be possible to port the WD definition to ABAP and have the ABAP runtime generate the application again in ABAP. I expect that any custom code that is written in JAVA would need to be manually rewritten in ABAP - but it would be great if there was tool or method to at least port the majority of the application.
Thanks in advance for your help,
Simon

Hi Simon
You are correct in thinking that all WD apps are based on metadata, but unfortunately, the similarity between WD Java and WD ABAP is just a conceptual one, and no such tool exists to convert one to the other.
In addition to this, there are certain implementation differences between ABAP and Java that mean you could not convert one to the other. For instance, the whole concept of model objects does not exist in WD ABAP. Therefore, structural entities used in WD Java such as model components could not be tranlsated into anything that exists in ABAP, because the concept is redundant in the target language.
Sorry about that, but Java and ABAP are sufficiently different beasts that such a tool is not possible.

Append Data from Java Web Dynpro to an Internal Table in ECC

Hi,
Currently I am using AdaptiveRFCModels to creating/updating records from Java Web Dynbpro to FM in R/3. Users can add few records before they save the changes. The current design is Java Web Dynpro call RFC FM when user add/edit one record. The record will store in an global internal table in the Function Group. For example, I have added 3 records before I save the changes. It means that global internal table should have 3 records that I added before I save it. But in fact, the global internal table only store one record while I adding the third record. The global internal table not able to keep the previous records. The code below is how I code to execute the FM from Java Webdynpro. Is the code can work as I expected? Anything missing in the codes? Please advice. Thanks.
wdContext.nodeZhr_abc_Input().bind((Zhr_abc_Input) model.createModelObject(Zhr_abc_Input.class));
Zhr_abc_Input objReq = new Zhr_abc_Input();
Zhr_Pad31 insUpdVer = new Zhr_Pad31();
insUpdVer.setQ_Id(wdContext.currentContextElement().getQ_Id());
insUpdVer.setZ_ce(wdContext.currentZhr_Detail_OutputElement().getZ_ce());
objReq.addLt_Pad88(insUpdVer);
wdContext.nodeZhr_abc_Input().bind(objReq);
wdContext.currentZhr_abc_InputElement().modelObject().execute();

According to your code you are setting only one record.
You have to create 3 elements for each record and add all the three to the nodeZhr_abc_Input node.
If I understand correctly, node currentZhr_Detail_Output is the one which is containing all the three records. Loop through this node, pick each record and set to the input node.
wdContext.nodeZhr_abc_Input().bind((Zhr_abc_Input) model.createModelObject(Zhr_abc_Input.class));
for(int i=0;i<wdContext.nodeZhr_Detail_Output().size();i++)
Zhr_abc_Input objReq = new Zhr_abc_Input();
Zhr_Pad31 insUpdVer = new Zhr_Pad31();
insUpdVer.setQ_Id(wdContext.currentContextElement().getQ_Id());
insUpdVer.setZ_ce(wdContext.nodeZhr_Detail_Output().getElementAt(i).getZ_ce());
objReq.addLt_Pad88(insUpdVer);
wdContext.nodeZhr_abc_Input().addElement(objReq); // Changed from bind to addElement
}//for end
wdContext.currentZhr_abc_InputElement().modelObject().execute();
Note: I just typed the code. Syntax might be wrong here and there. Please correct it while coding.

Jaya.

ABAP Web Dynpro V/S JAVA Web Dynpro

We need to pick developing technology between ABAP Web Dynpro v/s JAVA Web Dynpro. Is technology better than other in terms of security, scalability? There is lot of documentation on the web but it is very old and out dated. I am pretty sure things have changed quite a bit with recent versions of SAP. Any feedback is greatly appreciated.
Thanks.
PS: I Used Web Dynpro for ABAP at my previous client for SAP SRM without a problem.

Dear Sap Fan
This has been a long and interesting debate on SDN.
You will find plenty of posts discussing this matter.
But there's no clear winner, I warn you.
;o)
This one in particular is very good:
[http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/e0e4940c-035c-2b10-0b9d-eb8f99674f4e]
But you can also check these others:
[webdynpro java or abap;
[Webdynpro Java or ABAP;
[Webdynpro Java or ABAP;
[Webdynpro Java or Abap ?;
More and more you see clients migrating from WD4J to WD4A.
Guess SAP is also heading into that direction, perhaps because Oracle bought SUN sometime ago.
I'm comfortable on both environments I have to say.
I have more than 10 years with development.
I know ABAP from inside out.
I also know JAVA and I'm certified with this technology.
But I personally prefer WD4A.
Why ?
Because you don't need to use NWDI.
Because you don't need to configure JCO's.
Because you integrate seamlessly the development with the transport framework (requests, etc..)
Because debugging is great.
Because plenty of traditional ABAP tools (trace, logs, performance analysers, etc..) can also be used with WD4A
Because you don't need to worry with NWDS...just type SE80 and you're there... ;o)
And I could go on and on....
But then again, it all depends:
Do you have a lot of good in-house JAVA knowledge ?
Do you use a lof of Custom JAVA development in your company ?
Are you planning to use standard SAP (ESS/MSS or others for example) ?
I'm not saying that WD4A is "better" than WD4J.
There's no such thing.
Each option has its pros and cons.
You also can't tell that WD4J is more secure or scalable than WD4A. Or the opposite.
And, believe me, WD4J is still going strong with a lot of customers.
But things are changing, and for me WD4A would make more sense if you want to be aligned with SAP.
Now and in the future.
Kind Regards

Problem in calling XI generated Web Service via Java Web Dynpro

Hi experts,
I have problems with calling a web service, which was created by XI. I have already tested the web service with Altova XMLSpy. The Web Service works fine.
But when embedding this web service into Java Web dynpro application no message flow is given. I have two views one Selection View and one Result View which should show the answer sent by RFC-Call.
<b>My Settings in NWDS:</b>
During configuration of web dynpro I have choosen 'Import adaptive Web Service Model' --> Select wsdl file via local file system --> 'no logical destinations - use WSDL URL for metadata retrieval and web service execution'.
The model is also not shown in diagram view although I have added into the diagram.
The web service was created on XI 7.0.
Should I do any other settings e.g. in Visual Administrator, Web Dynpro Content Administrator?
So can anybody help me.
Thanks a lot.
Regards,
Mario

Hi Aviad,

Can anybody help?

Ok looking for the solution i figure out that it won't be possible anyway, i need a first log to the portal in order to issue a logon ticket before any attempt of SSO authentication.

R/3 search helps in java web dynpro

Hello,
A customer of ours has some Z transactions in its R/3 system, which basically present a very simplyfied version of MIGO. This Z transaction makes extencive use of Search Helps, which in some cases have been extended.
A ABAP developer with some Web Dynpro experience showed me that it was easy to integrate these search helps into his web dynpro application.
I cannot find how to do this in java web dynpro with the developer studio. Is this possible and if yes, how?
Greetings, Walter.

Hi Walter,
You can use search helps in Web Dynpro for Java also. The feilds with check table in R/3 automatically give search helps. To provide explicit search help you need use EVS or OVS.
These are the tutorials

Settings SLD and JCO connection for Java Web Dynpro

Hi BI Gurus,
I'm a Business Intelligence newbye and I'm a bit confused about Web Dynpro configurations.
I try to execute, through Netweaver Developer Studio 7, a simple java Web Dynpro who call the standard Flight List BAPI.
My configuration is: NW 2004s installed on BI server (with java instance and j2EE Server) and Flight List BAPI stored on R/3 ECC. 5 System in another server.
Now, my doubt are:
1) in SLD Data Supplier (J2EE Visual Admin on BI Server) CIM configuration, what are the connections parameter necessary?The BI host or R/3 host?
2)if I set BW system parameters in SLD and in NWDS when I try to run my simple web dynpro an error occour This is the output:
The initial exception that caused the request to fail, was:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeException: Failed to resolve JCO destination name 'WD_FLIGHTLIST_RFC_METADATA_DEST' in the SLD. No such JCO destination is defined in the SLD.
Correction Hints
Accessing the System Landsape Directory (SLD) failed. Depending on the concrete reason (see root cause) check the following:
is the SLD Supplier in the J2EE engine configured correctly? See the SLD documentation for more details about the SLD and about how to configure it.
are all JCO destinations maintained correctly? Use the preinstalled Web Dynpro Content Admin application to check/edit the destination. Use the Ping and Test functions of the Content Admin to verify that each destination is properly configured.
Additional information about the System Landscape Directory and the Web Dynpro Content Admin can be found in the SAP Developer Network (SDN) and in the Online Help for the SAP Web Application Server (installed with SAP NetWeaver Developer Studio and available online).
Note: the above hints are only a guess. They are automatically derived from the exception that occurred and therefore can't be guaranteed to address the original problem in all cases.
3)where can I create new JCO connections?What are the requirements settings?
I am always available for answers about the post!!
Help me please!!
Thanks thousand and sorry for my incorrect english!!

Andrea,
You can Create the JCo destination from Content Administrator. You must login as Administrator.
use the link as
http://<server>:<port>/webdynpro/welcome/Welcome.jsp, select Content Administator->Create JCo Destinations/Maintain JCo Destinations.
Please have a look on the following links regarding creating/maintaining JCo destinations. The are usally asked questions regarding JCo destinations.

Java Web dynpro with ABAP Clients?

Morning,
We have a situation where we would like to use a Java Web dynpro with multiple ABAP backend data sources. This is for autorization as well as data. We are not using Enterprise Portal.
We've created a pair of system Jcos and mapped them to the Web dynpro via the URL. This works and the correct data from the correct Client is retrieved depending on which pair of Jcos we define in the URL.
The problem we are having is that we are only able to logon using the ABAP Client defined in the ume....master.client parameter.
Is there a way to achieve this (again without EP) either in the system configuration or programatically in the web dynpro?
tia
Cheers,
Mitch

Hello,
Thanks for the updates. Actually my query is we have a SCM 5.0 system which has a java stack in it. But now we are going to upgrade it to SCM 7.0. - Is SCM 7.0 has a java stack ?
If it doesn't have , can we upgrade SCM 5.0 to SCM 7.0 without Java Stack ? Is it posssible to upgrade without Java Stack or not ?
Is it possible that we can convert Java Stuff into ABAP web dyn pro ? If yes , how shall we can achieve it ? If not, how shall we proceed in an alternate way ?
Thanks for your help in advance.
