How to empty a node under Java Web Dynpro?

Hello,
I want to empty a node in the controller, I tried several attempts to do so, but no attempt is good.
I would like to know if someone already met this problem? If yes, please give me the solution.

Hi,
The invalidate() method for node should work to clear the nodes element collection.
else we can set "" to each context attribute in a node.
If your node cardinality is 1..1
wdcontext.current<nodeelement>().setname("");
if your node cardinality is 0..n
for (int i=0;i<wdcontext.node<nodename>().size();i++)
wdContext.node<nodename>().get<node>ElementAt(i).setname("");

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!

How to create table in interactive form via Java Web Dynpro

Hi,
How to create table in interactive form via Java Web Dynpro ?
Any online tutorial / example ?
Thank you.
Regards,
Eric

Hi Eric,
Just choose the UI element Table from Form Library and drag and drop it on the form. now choose the no. of rows and columns and other settings you want about table from the wizard initiated through this process. This all is what you have to do to create the table. Now to bind it to the fields of the data source bind the individual colums to individual attributes of the node in the datasource.
Hope it will solve your query.

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.
Vaibhav Tiwari.

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.

How to avoid directory listing in java web applications.

how to avoid directory listing in java web applications.
That is on typing the url of the application it should not the directory listing. Welcome tag in web.xml doesnot fully solve the problem, since still the images folder etc is still accessible

I know of two ways.
If you're using tomcat and have access to the conf directory.
Edit your $TOMCAT/conf/web.xml. Find your default servlet properties and change
<servlet>
    <servlet-name>default</servlet-name>
    <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
    <init-param>
      <param-name>debug</param-name>
      <param-value>0</param-value>
    </init-param>
    <init-param>
      <param-name>listings</param-name>
      <param-value>true</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>to <servlet>
    <servlet-name>default</servlet-name>
    <servlet-class>org.apache.catalina.servlets.DefaultServlet</servlet-class>
    <init-param>
      <param-name>debug</param-name>
      <param-value>0</param-value>
    </init-param>
    <init-param>
      <param-name>listings</param-name>
      <param-value>false</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>And restart your server. This will affect every directory on the server, and return a 405 directory browsing forbidden error.
Another way, is to place an index.jsp inside each directory with a simple one line redirect to your applications CONTEXT_PATH.response.sendRedirect("http://yourserver/yourapp/");This will only affect specific directories which contain these index.jsp files.
Hope this helps

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

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.
Regards,
Jaya.

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?

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.

Hi Naidu
I have written the contents of the pdfsource to a file in the server using the below code:
byte b[] = wdContext.currentContextElement().getPdfSource();
File file = new File("C:
Severance.pdf");
long length = file.length();
FileOutputStream os;
try {
     os = new FileOutputStream(file);
     os.write(b);
     os.close();
catch (Exception e)
     // TODO Auto-generated catch block
     wdThis.wdGetAPI().getComponent().getMessageManager().reportSuccess("Some Exception "+e);
     e.printStackTrace();
And i have added a File Download element in the Application and have implemented the below piece of code for it:
IWDAttributeInfo attInfo = wdContext.currentContextElement().node().getNodeInfo().getAttribute("ctx_downloadpdfsrc");
ISimpleTypeModifiable type = attInfo.getModifiableSimpleType();
IWDModifiableBinaryType binaryType = (IWDModifiableBinaryType) type;
binaryType.setMimeType(WDWebResourceType.TXT);
String fileName ="C:
Severance.pdf";
// path to the source file
/* converts the binary file to a byte array and moves it to the text element */
try
      File file = new File(fileName);
      FileInputStream in = new FileInputStream(file);
     ByteArrayOutputStream out = new ByteArrayOutputStream();
     int length;
     byte[] part = new byte [10 * 1024];
     while ((length = in.read(part)) != -1)
           out.write(part, 0, length);
      in.close();
                          wdContext.currentContextElement().setCtx_downloadpdfsrc(out.toByteArray());
catch(Exception e)
                          wdComponentAPI.getMessageManager().reportSuccess(" !!!!!!!!!!!!! "+e);
                          throw new WDRuntimeException(e);
Other than this, if we simply write this line in the code it will display the entire content of the pdfSource on the screen when deployed:
wdComponentAPI.getMessageManager().reportSuccess(wdContext.currentContextElement().getPdfSource().toString());

Java Web DynPro and Universal Worklist Interaction

HI ESS/MSS Gurus,
Good day!
I am a workflow consultant who is working on an ESS/MSS project. I have already completed and tested (successfully) all of the workflows needed in the backend using the PTARQ and PTCOR applications. We are also successful in showing the work items in the universal worklist.
Now the question is, whenever we click on the work item, we encounter an error in the portal. Now, I need to determine the following:
1. How are we going to integrate the ESS/MSS portal with the execution of the work item in the universal worklist?
2. Do we need to develop custom Java web dynpro applications for the approval process of the leaves, or is there a standard offering from the ESS/MSS packages?
Your inputs are very much welcome.
Regards,

Hi Gurus,
Here is what we have done so far:
1. Implemented the details as indicated in note 779075 and changed the parameters defined in SWFVISU
2. Upon re-registering and clearing the cache from the UWL, we tested if the task will call the standard application for leave request approval. It returns the error Internal error. :
Item is null for action acknowledge, and for item type uwl
It seems that the xmls files are not being generated or read successfully. although when we check uwl.webflow.SAP_ECC_HumanResources, there is an updated xml file for the task
Questions are:
1. What checks do we need to execute between the back end, UWL and portal?
2. Whenever changes in SWFVISU are made, what items do we need to check to ensure that the changes are reflected in the UWL? I have read that SWFVISU helps the user do away with the tedious xml creation. How can we verify that the changes are implemented/updated in the xmls generated?
3. Any other items we need to look into?
Regards,

Sending java web dynpro interactive form as pdf attachment from Business WF

Hi,
I have a java web dynpro application with interactive form(online), on send button click i need to send the filled form as an PDF attchment to internet mail id. I am using SO_NEW_DOCUMENT_ATT_SEND_API1 inside workflow to send attachment. My custom RFC which is interacting with WD app is getting the pdf source context attribute(simply i set the import parameter with that attribute and no juggling is done) as import parameter which is of type XTSRING. Once i execute the application i am getting mail with attachment as pdf but i am not able to open the pdf. It is of just 1 KB size. It seems my pdf source context attribute is not sending data. Can some one suggest how can i solve this.DO i need to convert the data to pdf format before sending or any otgher thing i need to do.
Regards
Ravindra

I did that before posting the question itself (enables = false), it doesn't work. It just disable the extra features like digital signature and stuff. Interesting thing is all our HCM forms developed for HR actions works fine with out any issues. Why the interactive form developed with WDJ is not working and it requires credentials??. The same form works fine if I deploy the application directly into server but it throws the error if I check in through NWDI ..
If you look at the server location it has the file but it throws the error:
Caused by: com.sap.tc.webdynpro.clientserver.adobe.pdfdocument.base.core.PDFDocumentRuntimeException: IOException occured while creating template stream from the TemplateSource : .\temp\webdynpro\public\sap.com\ess~ben\webdynpro\Components\com.sap.xss.hr.ben.reviewtable.VcBenefitsReviewTable\ReviewTableView_InteractiveForm_Review.xdp (The system cannot find the file specified)
Please advise.
Thank You,
