Playing sound/beep on the handheld device using WebDynpro for Java (NW7.01)

Does anybody know if we could play sounds or beeps on the handheld device using WebDynpro for Java (NW7.01)? We have a client requirement to have the handheld device beeps/makes different kind of sounds after the goods receipt is posted. We are looking for a way to play the sounds thatu2019s saved on the deviceu2019s directory. Appreciate any suggestions or input.
Thank you!
Teeracha

Hi Terracha,
you can use bellow mentioned methods for playing a sound using javascript :
function playSound( url ){
document.getElementById("sound").innerHTML="<embed src='"+url+"' hidden=true autostart=true loop=false>";
or

$.playSound('http://example.org/sound.mp3');
Hope that helps you as a workaround way.

Can we Change the backround color of an Input field in Webdynpro for ABAP.

Hi Experts ?
Can we change the background color of an Input field in WebDynpro for ABAP based on results we receive from any function module or BAPI?? .
Thanks in advance .
Regards ,
LAS

Yes. We can change the background of an input field. The way you do this is by editing the theme that webdynpro application uses. To edit the theme, you will need to install NWDS PLUS the theme edit plugin (Available for download from SAP).
Once you have edited the theme, you will need to upload your theme back to application server. You can use the program : BSP_UPDATE_MIMEREPOS to do this.
Bydefault, the theme used by webdynpro applications is :
/SAP/PUBLIC/BC/UR/nw5/themes/sap_tradeshow
You can apply another theme by calling the webdynpro application with a theme parameter. For example, if my webdynpro application name is "zgopaltest", then
http://<server>:port/sap/bc/webdynpro/sap/zgopaltest?SAP-EP-THEMEROOT=/SAP/PUBLIC/BC/UR/nw5/themes/sap_tradeshow
will apply the sap_tradeshow theme.
Likewise, you can apply diffrent theme. There is another theme that SAP provides. Its called : sap_hcb. Hence, you can apply the theme to the above application by:
http://<server>:port/sap/bc/webdynpro/sap/zgopaltest?SAP-EP-THEMEROOT=/SAP/PUBLIC/BC/UR/nw5/themes/sap_hcb

Adobe Interactive forms & WebDynpro for java problem with IE7 and IE8

I have Interactive form ui-element in WebDynpro for java (ver. 7 SP 10) application. It works fine with IE6, but in IE7 (or IE8) it doesn't show that ui-element at all. We have tried to change IE7 security & advanced settings, but we have not made any progress. We have also tried to install/uninstall different Adobe reader versions etc.

I know a little more about the problem now. After viewing the XML source I change the property of the inputfield.
It was like this:
<field name="verdipers_felt" y="130.7001mm" x="180.1801mm" w="101.6004mm" h="44.4501mm" locale="no_NO" access="ReadOnly">
but i changed the access to be nonInteractive
<field name="verdipers_felt" y="130.7001mm" x="180.1801mm" w="101.6004mm" h="44.4501mm" locale="no_NO" access="nonInteractive">
now view2 shows the linebreak as in view1... Buut! when im going back to view1 from view2, the linebreaks gets converted into spaces
thats pretty wierd, aint it?

Problem in connecting to database from webdynpro for java

Hi
I have a problem in connecting to database from webdynpro application
I am using oracle 10 express edition as database and was able to connect to database from a java application.But was unable to connect from a webdynpro for java.
I guess webdynpro for java uses open sql instead of vendor sql(I looked in the visual admin ,DB is using open sql) so unable to connect to database.Am i right.?
Do i need to make any settings in the visual admin to make it work?
How to solve this problem.Please give me pointers
Thanks
Bala

Hi,
For connecting to Oracle, either you can use the normal JDBC connectivty code directly which is given below :
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@Oracle_server_ip:Oracle port:SID of the Database","user_name","password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("your query");
In case you want to fetch data through ejbs, these are the steps to be followed :
1) Open the J2EE perspective
2) Create an EJB Module project
3) Right click on ejbModule, create a new EJB (select your EJB type)
4) While creating the ejb itself, you can add business methods by clicking Next in the UI. Another option is after creating the ejb, write the method in the bean, then select the method from ejb-jar.xml -> <bean name> ->method. Right click and select propogate to local & remote.
5) Double click on ejb-j2ee-engine.xml. select your bean and specify a Jndi name for eg: MyJndi.
6) Right click on the EJB project and add classes12.zip file (provided by Oracle) to its build path. (under libraries tab). Also check the same file under Order & Export.
7) Create an Enterprise Application project.
8) Right click on the EJB module project and select add to EAR project, then select the created EAR project.
9) Right click on the EJB project, select Build EJB Archive
10) Right click on the EAR project, select Build Application Archive
11) Open the WebDynpro perspective, open a new project, right click on the project ->properties. Do the following configurations :-
Java Build path - select the EJB project from projects , check the selected project under Order & Export
Project references select the EAR project
WebDynpro references select sharing references tab, click add & make an entry as : <vendor>/<EAR project name without .ear extension>
You can find the vendor name under application-j2ee-engine.xml file of the EAR project. By default it is sap.com. So if my EAR projects name is ABC, my entry would look like sap.com/ABC
12) Now the configurations are over and the EJB can be invoked by writing the client code inside the webdynpro component. Like:
InitialContext context = new InitialContext();
Object obj = context.lookup("MyJndi");
MyEJBHome home = MyEJBHome)PortableRemoteObject.narrow(obj,MyEJBHome.class);
MyEJB mybean = home.create();
int a = 0;
a= mybean.add(10,15);
wdContext.currentContextElement().setSum(a);
where MyEJB is my EJB name and MyJndi is my JNDI name
To connect to Oracle , you can write the usual Java code (given below) as a business methos of the ejb (similar to add() method in the example). And access it like mybean.<businessMethodName>().
DriverManager.registerDriver(new oracle.jdbc.driver.OracleDriver());
Connection conn = DriverManager.getConnection("jdbc:oracle:thin:@Oracle_server_ip:Oracle port:SID of the Database","user_name","password");
Statement stmt = conn.createStatement();
ResultSet rs = stmt.executeQuery("your query");

Create a ViewSet with properties column 1, rows 3.
1. In the tool selection list, select Embed View.
2. In the layout area of the Navigation Modeler, click on the cell of the view set in which the view is to be embedded.
3.In the wizard, choose Embed New View and, in the next window, enter a name for the view.
4.Use the package that you entered for the component definition or select another package by choosing Browse.
5.Choose Finish.
Create 3 views with names search screen,results screen and detail screen.
Use plugs to navigate.
II. Display one view at a time:
Create a main View. Insert ViewContainerUIElement
Open Navigation Modeler.
1. In the layout area of the Navigation Modeler, click on the cell of the ViewContainerUIElement.
2.In the wizard, choose Embed New View and, in the next window, enter a name for the view.
3.Use the package that you entered for the component definition or select another package by choosing Browse.

RE:(URGENT)WebDynpro For Java

hi all,
I have done an application in webdynpro for java that i.e accesing a java Bean by creating a model.
In my model i have taken three variables i.e a,b,c
after that i have exported the jar file of that bean...and i have created model in my webdynpro application.
in that model i have taken that jar file and i have taken in used model to....
After that in diagram view of the webdynpro componnt i have mapp that model to cntroller and from controller to the view after that i am able to use the three variables from the bean as my context attributes.....
so i have binded those attributes(from Bean) to inputfields in view layout....
so after that when i have deployed the webdynpro application the input fields are getting disabled so iam not able to give any values....
and when iam clicking the submit button the error iam getting is null pointer exception....
even i have tried with different cardinality values of that node ......but my problem was not solved so plz help me out in solving this issue as soon as possible.............

HI Mahesh,
If you have mapped variables correctly then check following
Your variables a,b,c wherever you declared them instantiate them.
and be sure that that getter setter methods are exist.
e.g if a,b,c are in your bean file then
as a = new a's class,
and check getter methods for a
i.e. getA() and setA(a's class) methods.
after this export as jar and use this new jar to create model.(It will be good if you create a new model deleting prv one)

Hi
If you want to try out using ADOBE Flash Islands with WDJ, you would need to download SAP CE 7.1 EhP1 trial version, if not done so already.
The following link may help you in building the WDJ component with Flash Islands..
The specified item was not found.
If you donot want to develop the Flex project you can download the .swf file provided by the SAP mentors:

How to access(connect) BI Data in webdynpro for java applications

Hi ,
is there any way to access and display the BI data in portal using webdynpro for java applications like we did in Visual composer.
if not how to integrate the BI data in webdynpro applications ?
Regards,
Govindu

Hi,
Yes there are ways to do it. But may your scenario and the scenario for which I have done may differ.
You can use openhub to get the data in a flat file and then read it into weddynpro through a java service OR
You can use DBlink(which i have done).
Please refer the link below:
[Link|Data from BW to Oracle.;
This I have done in NW04s. Not sure whether a better solution is available in the newer release.
Hope it helps.
