Compiling web dynpro using javac

I am writing an ant script to build ear file for my web dynpro application. We can not want to use Netweaver studio because our build process is automated using ant. In my web dynpro application there are 45 java files including my own java classes & the java classes generated by netweaver studio. But in my app.jar file there are 80 java classes. if I can locate all the java files then I can use javac to compile these classes & create ear file independent of netweaver studio.
Has anyone tried using ant to build ear file for a webdynpro app? How are these extra classes created without corresponding java files?

Hi Sam,
        Webdynpro is a framework within the Studio.The meta model of it requires all the jar files for compilation.You can see all jar files in the plugin folder of the same.If you can export all these jar files
then I think you can compile and run your script outside studio but surely it is a tedious process.Moreover when you want to run any webdynpro application it is designed to open an IE with the framework.Lot of work around has to be done for opening external browser for running it other than studio.
          Hope my points briefs your query.
       Can you tell me the reason why you don't want to compile it within the studio?
Regards,
Guru

Error while compiling Web Dynpro program due to missing JAR files

Hi Experts,
I am getting error message while compiling Web Dynpro program. The erring lines are as below:
          Message message = new MimeMessage(session);
          try {
               message.setFrom(new InternetAddress(fromMailId));

                    Message.RecipientType.TO,
                    new InternetAddress(toMailId));
               message.setSubject(mailSubject);
               message.setText(mailBody);
               message.setHeader("X-Mailer", "E-Mail");
               message.setSentDate(new Date());
               Transport.send(message);
The error messages are:

Can you please help me in resolving the issue. It seems that some API is missing. I believe if some one can tell me the name of JAR file / API then I will be able to sort out the issue. I will add these JAR file in my program.
Thanks,

HI Stuart,
you are missing the jar files required for sending mail in java
Installing JavaMail
You will need the latest version of JavaMail (Version 1.2) available here:
http://java.sun.com/products/javamail/
Download and unzip the file, in the newly created top level JavaMail directory you will find a number of jar files,
these need adding to your classpath.
To do this in Eclipse, right click on your project in the tree view, select properties, select the libraries tab.
Now click the 'Add external jars' button, navigate to your JavaMail directory and click on the jars.
The tutorial also makes use of the Java Activation Framework, which is available here:
http://java.sun.com/products/javabeans/glasgow/jaf.html
Instalation of JAF is identical to JavaMail
activation.jar / mail.jar are 2 distinct names i remember rest you will get above
P.S: close the question to assist other users narrow the search and find solutions

Search help for Web Dynpro using the SAP-search help

Hi,
Im trying to create a generic search help for Web Dynpro using the SAP-search help. It should working so, that I construct a Web Dynpro-component, that gets the data of the search help from the SAP-system, interpreted it and creates the ui-elements and the needed context generic.
The mapping between the Input field of the customerview and the right search help is to be made with an xml-file, which contains the information: name of the view, the input field, the search-help-name and the name of the field that will be returned.
The xml-file is reading from a helper-class. That helper-class contains any information, witch need the search help-component as well as the customer-component.
The initialization takes place in the method wdDoModify of the customer. The call of the search help from the customer should be implement with an Action, witch is bound to a Button(create dynamic in the helper-class behind the input field).
In a second foot should be create a plugin for eclipse, witch insert the used files (search help component, helper class, ) in the project. In addition it should create the call in the customer generic.
It would be great if someone can give me a feedback!

Hi Mike,
The BlanketAgreement.exe is a reference to the executable that will be created when you compile the solution you created in Part II - Part III. I think there is a mistake in the tutorial because it asks you to name the project 'Blanket' which means that by default the executable will be called Blanket.exe and not BlanketAgreement.exe. The tutorial also misses the step asking you to compile the Blanket project before you go on to create an installer. You should compile your Blanket project in Release mode before creating an installer. By compiling the project you'll get a Blanket.exe file in the bin folder of your Blanket project which you then need to add to the installer per the instructions.
SAP do offer development courses in some areas and there is training material here on the SDN and on the SAP partner portal (and maybe the customer portal as well). Try searching this forum for 'training' or 'tutorial' and you should get a few links. There's also a development certification.
Personally I'd recommend you give yourself a little project to work on and just get stuck in

Srm 7.0 - Hide field in web dynpro using configurations

Hello to all,
I'm trying to hide some fields on PO web dynpro. In this example on web dynpro /SAPSRM/WDC_DODC_PO_I_BD I start the component configuration /SAPSRM/WDCC_DODC_PO_I_BD, I search for the fields I want to hide and put the visibility attribute to Invisible and I mark final check box.
The fields don't dessapear from the web dynpro. Am I missing something?
Best regards,
Nacho

Thanks for your reply.
I have here two situations:
SPRO. If I add the field on Configure Field Control at Header Level/Item Level it disapears but not all fields appear on this transaction. For example, I can't do that to tolerance group (TOL_GP)
Webdynpro. Using Component Configuration of the dynpro. I guess that it is in two actions:
   - Change the value of visibility to Invisible on Web dynpro Built-In
   - Add field to context. I put for this example:
         Attributes of the Element usagesDefinition (ITEM_TOL.TOL_GP)
                 usageName ITEM_TOL.TOL_GP
                 componentName ITEM_TOL.TOL_GP
                 ConfigurationName /SAPSRM/WDCC_DODC_PO_I_BD
The webdynpro way doesn't work, Am I missing something?
Best regards,

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.

But I am getting the error if_image_view does not exist.
Please help me and guide me if I am proceeding in a wrong way.
Thanks and Regards,

Hi ,
Its very simple ....
Dont use any transaction to upload image.
right click on component and select
create->mime_object->import
suppose ur image is on desktop...
So select the path of desktop select the image and click ok.
U will see an MIMEs named folder in ur component and under which u will have ur image.
now add image element into UI and there u will have source name property ...just write the name of ur image file and test ur application.
U can see the image in output..
(Also there are different properties of image element to set the position and other things)
any queries ..feel free to ask
regards
panky

Cannot import DCs, necessary for Web Dynpro use in CAF GP

Hello!
I'm a newbie in SAP technologies. I want to develop a Web Dynpro (WD) application, which will be used as UI in CAF GP. The problem is that I cannot import necessary DCs for this!
As I understand, the following ones are necessary to develop a WD app for use in GP:
caf/eu/gp/api
caf/eu/gp/api/wd
com.sap.security.api.sda
(according to http://help.sap.com/saphelp_nw2004s/helpdata/en/b2/06ae42848bb211e10000000a155106/content.htm)
I acted as it is described in "Implementing a Web Dynpro CO which Implements the GP Interface" (https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/50d74ada-0c01-0010-07a8-8c118d408e59).
Actually, those DCs don't exist in my local configuration - so, as it is told in "Implementing a Web Dynpro CO which Implements the GP Interface", I tried to get the DCs from remote host (there's a server in Intranet with all stuff installed). In NetWeaver Dev Studio, in "Preferences -> Development Configuration Pool" I have written http://<local server>:50100. Actually, I don't know, what port should be used - I've written the one, which handles requests to SAP NetWeaver Portal. The response to "ping" button click is "HTTP response code: 403 (Forbidden)".
I tried to check the status of SLD, and went to http://<local server>:50100/sld. I have successfully logged in, but when I try to go to tab "Administration", I receive the message " 403 Forbidden. You are not authorized to view the requested resource."
Is there a problem with my roles & groups? Actually, I'm in group SAP_SLD_ADMINISTRATOR.
What is wrong?
How can I get the detailed information about the error (log files or something)?
Thanks in advance!

Barry, as I understand, I have no these roles, available for granting. Maybe, I've acted in a wrong way (the version of SAP NetWeaver is "Release 2004s".):
I logged in NetWeaver portal as administrator, went to section "User administration", selected my user, opened the tab "Assigned Groups" and searched for the groups you've written - I found no one

Web dynpro using a portal service

Hello All,
We are using the JDI.
We want to use a portal service DC from a web dynpro DC.
The web dynpro DC is part of a software component.
When the portal service is a local DC it is working fine (except failing later on the CBS build)
but when the service is part of a software component as well I get a runtime exception: a java.lang.NullPointerException.
The WD sharing reference I'm using is: PORTAL:sap.com/<dc service prefix>.<service name>
I assume that this is the right reference because without this exact phrase I get a java.lang.NoClassDefFoundError: com/sap/<name of service>
<b>Does anybody know how to use a portal service that is part of software component?</b>
Thanks a lot in advance, Adi.

Thanks Bharathwaj , but I already solved my problem.
The solution was to change the next code line in the service client code :
Idb_srv DB_Service = (Idb_srv) WDPortalUtils.getServiceReference(Idb_srv.KEY)
to:
Idb_srv DB_Service = (Idb_srv) WDPortalUtils.getServiceReference(""<PARFilename>.<service name>");

Web Dynpro using EJB to implement database access for MS SQL 2005 server

Hello,
For using EJB model in Java Web Dynpro, why do I need another dictionary project with all the required tables (there are 5 tables in my project), when the same database is already created in back end MS SQL 2005 Server.
Thanks
Srinivas

Thanks for your reply Charan,
I am fairly new to EJB. I have created only one session bean (called TrainingBean) and created all the business methods inside it.
Here is my database schema, with the following 5 tables
Courses
CourseSchedules
Students
Registrations
Competencies
Here are the session bean business methods:
changeCourse(String)
changeStartDate(String)
createCourse()
createCourseSchedule()
getCourses()
getCourseSchedules()
registerStudent(String)
unRegisterStudent(String)
Is this good way to implement EJB, or should I create multiple session beans and multiple corresponding Data access command beans ?
Thanks a lot
Srinivas

CompileException: Error compiling web service (using ant jwsc)

Hi,
I try to use the ant task jwsc to create my portable artefacts for a web service.
Unfortunately I get the following exception:
BUILD FAILED
C:\Sun\jwsdp-2.0\apache-ant\bin\build.xml:7: weblogic.wsee.tools.jws.build.CompileException: Error compiling web service: C:\Sun\jwsdp-2.0\apache-ant\bin\src\test\WsTest.java
I do not know why the ant task can not compile my jws file (shown below) whereas Eclipse can!
package test;
import javax.jws.WebService;
@WebService (name="WsTestName", serviceName="WsTestServiceName")
public class WsTest {
* @param name
* @return Say hello to the person.
public String sayHello(String name) {
return "Hello, " + name + "!";
I hope somebody can help me.
Thanks
Franz

I thought I would post an update since I found a solution. The problem was a ClassCast exception in a part of the SSL stack, that wanted to use the ant BuildException class. This has the effect of hiding the real issue which was that the SSL connection was not successfully occuring. The real problem was that the SSL connection started with a WSDL retrieved via SSL, but the connection for the port was through a username/password. When a username/password is used to create a port, the WL stack falls back to http and causes a ClassCast exception on weblogic.wsee.connection.transport.http.HttpTransportInfo. The solution is to create an https transport object when the service impl is created:
HttpsTransportInfo transport = new HttpsTransportInfo ();
transport.setUsername (user.getBytes ());
transport.setPassword (pass.getBytes ());
gServiceImpl = new PersistenceManagerService_Impl (url, transport);
and to create the port without parameters:
port = getServiceImpl ().getPersistenceManagerServicePort ();
This allows one-way SSL with username/password for the connection.
