How to Pass Java Objects between Web Dynpro and Java SAP iViews

Basically I have an SAP web dynpro iView that I do stuff with and I want to pass an object to another iView which is just a regular Java iView. From what I've read and tried, I can't just stick something in the session object and hope that the Java iView can pull it down the other end. I had a dream that it was possible (seriously).
Anyway, are there any possible solutions around? Please advice and share you throughts. I will try to dream about it again tonight and see if its really gonna work this time.
thanks for your help in advance

There is no easy way you can pass objects other than those supported by express such as String, map, list etc.
Though not advised, you can create a class with static variables to handle the storage of such java objects during transition between form and workflow. You will need to somehow identify the objects uniquely .

Hi
you can use function module
data   ls_input_container TYPE swr_cont.
data   lt_input_container TYPE TABLE OF swr_cont.
CALL FUNCTION 'SAP_WAPI_START_WORKFLOW'
    EXPORTING
      task            = ptask
    IMPORTING
      return_code     = lv_return_code
      new_status      = lv_new_status
    TABLES
      input_container = pinput_container
      message_lines   = lt_message_lines
      message_struct = lt_message_struct.
where you pass the data in imnternal table "pinput_container" as
ls_input_container-element = 'KUNNR'.
ls_input_container-value = ls_skna1-kunnr ."wd_this->lv_kunnr.
APPEND ls_input_container TO lt_input_container .
ls_input_container-element = 'CLUSER'.
ls_input_container-value = lv_cluser.
APPEND ls_input_container TO lt_input_container .
ls_input_container-element = 'BUKRS'.
ls_input_container-value = lv_bukrs. " youe value as per requirement.
APPEND ls_input_container TO lt_input_container .
ls_input_container-element = 'VKORG'.
ls_input_container-value = ls_sknvv-vkorg. " youe value as per requirement
APPEND ls_input_container TO lt_input_container .
ls_input_container-element = 'VTWEG'.
ls_input_container-value = ls_sknvv-vtweg. "youe value as per requirement.
APPEND ls_input_container TO lt_input_container .
ls_input_container-element = 'SPART'.
ls_input_container-value = ls_sknvv-spart. "youe value as per requirement.
APPEND ls_input_container TO lt_input_container .
*Also Forgot to mention where ptask is your workflow ID *

How can I call a java object from Web dynpro ABAP application?

I made Web dynpro ABAP application and posted it to SAP EP.
For certain business purpose, we need to call external 3rd party java object using 3rd party's java api in Web dynpro application.
Is there anybody who experienced this kind of java interface issue?
I know Web dynpro Java environment can fully support this kind of requirement. but regarding Web dynpro ABAP, I couldn't find any clue for this.
Any comment or suggestion would be greatly appreciated.
Thanks,
Raymond, ABAP Consultant

if you have jco configured, then you can make calls to java api from ABAP .

Use HTTP Session to pass Object from Web Dynpro for Java to JSP page

Is it possible to get a handle on the HTTP Session object from within a Web Dynpro application? I want to place a Java object in there that can be retrieved by a JSP page.
Thanks in advance.

Hi Tom Cole,
You can try this. i am not sure if this will work or not.
HttpServletRequest request = ((IWebContextAdapter) WDWebContextAdapter.getWebContextAdapter()).getHttpServletRequest();
You can also try this.
IWDRequest mm_request = WDProtocolAdapter.getProtocolAdapter().getRequestObject();
HttpServletRequest request = (HttpServletRequest)mm_request.getProtocolRequest();
IWDRequest basically wraps the HttpServletRequest. if you are using NW04s then the getProtocolRequest() may not be available.

How to pass value object to BPM process and access process returned data

Hi,
I am new to Oracle BPM studio and gone through the tutorial. I did not find anywhere how to orchestrate the java components or ejb components or web services in BPM process. if any one provide sample business process orchestered with java component or ejb component or webservice, it will be great. Or atleast provide steps to do that.
Thanks and Regards
Mahesh Babu

There is a tutorial available online.. But you can always catalogue web services and JARs files into the ALBPM..
Just create a new module inside the Catalogue and then right click on it to see Catalogue Component and then select what component u want to add to ALBPM and then follows the steps of adding that component from your local machine and introspecting it..
If it is successful, then all the web-service methods or the JAR file methods would be catalogued into ALBPM..
You can put the WSDL address in the space provided for Web Services.. If password is required that too can be put..
Another way is to create a component in External Resources and then Cataloguing it...

Eventing between Web Dynpro iView and regular DynPage iView

I have seen, done eventing between two dynpage iviews and two webdynpro iviewsHowever, and gone through "How to Use the Portal Eventing for Web Dynpro iViews". However, I have been trying to have a webdynpro iview talk to a dynpage iview but they just won't communicate. Is this even possible?
Ok basically I have a portal page in a popup window with no masthead and top level navigation. The page has two iviews - the top one being an iView that points to a webdynpro application on Server A, and the bottom one being a dynpage iview on the Portal Server B.
In the webdynpro iview, the code for when a button is clicked is
public onSomeAction(Event event) {
    WDPortalEventing.fire("urn:myUrn","eventName","value");
In the dynpage iview, the code i have for it is
myServ = (IEpcfToolbox) PortalRuntime.getRuntimeResources().getService(IEpcfToolbox.KEY);
myReceiver = myServ.getClientEventReceiver(request, "urn:myUrn", "eventName");
form.addRawText(myReceiver.getWrappedScript());
try {
    if (!myReceiver.isReceived()) {
        form.addComponent(createMainScreen());
    } else {
     form.addComponent(new TextView("event received!"));
} catch (Exception e) {
    form.addComponent(createErrorScreen());
I tried all the things I could think of but the receiving iView just won't get the event fired.
Can someone confirm that this should work? and correct me where I've done wrong.
Please help. this is very urgent. your help will be greatly appreciated. thanks in advance
PS. My environments are EP 6.0 SP2 and WAS 6.40 SP14

I am no direct access to the boxes so I can't try your suggestion. It really makes sense that eventing won't work if the iViews are on different domains. I know they are in the same domain but different subdomains.
Anyway, good news I got eventing to work with the mentioned set. I found that that the SAP Java EPCFToolbox API had a bug that kept throwing javascript errors when I tried to have the web dynpro iview fire an event and the SAP one subcribed to it.
I got around it but using the EPCF Javascript API instead.
Code:
response.write("<script>");
response.write("EPCM.subscribeEvent('urn:dla.telework', 'createPdf', doSomething);");
response.write("function doSomething() {");
response.write("window.location = self.location + '&eventReceived=true';");
response.write("}");
response.write("</script>");
So basically just output raw text through the response object and it just works.
On a similar topic, since eventing can only pass string parameters back and forth, I'm still looking for a way to pass other more complex Java objects between web dynpro and sap iviews. From what I haven't they don't share the same session object (which I thought they did). So basically I can't just stick stuff in the session and pull it down on the other end. I'm clueless right now. If anybody has some tips, plesae share. Thanks

How can I set the data binding between Web Dynpro & Database table

Dear friend,
I am a beginner of Web Dynpro. I want to develop my simple project like these:
1. Create my own database table via Dictionary Project such as TAB_USER and have 3 fields: USER_ID, USER_NAME, USER_POSITION and I have already deployed & archived it.
2. Create my own Web Dynpro Project, and create the input fields as User ID, User name, User position and icon 'Save' on the selection screen and I have deployed it already.
For the process, I want to input data at the screen and save the data in the table, please give me the guide line like these:
1. How can I set the data binding between Web Dynpro and Database table ?
2. Are there any nescessary steps that I will concern for this case?
Sorry if my question is simple, I had try to find solution myself, but it not found
Thanks in advances,
SeMs

Hi,
You can write your own connection class for establishing the connection with DB.
Ex:
public class ConnectionClass {
static Connection con = null;
public static Connection getConnection() {
try{
Context ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("jdbc/TSPAGE");
con = ds.getConnection();
return con;
}catch(Exception e){
return null;
You can place the above class file in src folder and you can use this class in webdynpro.
You can have another UserInfo class for reading and writing the data into the DB .

My Page open normally in SAP Portal Page Admin, now i would like to know how do for include the Portal Theme, Menu, Status Bar into to my page.
I investigated about wdPortalNavigation and wdPortalNavigationMode, but i don't understand very well how insert the Portal Navigation properties into my Page.
How do I insert this properties in my iView Code? or I should set this properties in Portal Admin?
Somebody have some e-books or tutorials to indicated?
Thanks in advance!!

Hi Marcelo,
First of all welcome to SDN....
For you Webdynpro pages to open with new THEME but not with default theme of portal you have to design new theme in portal and assign that theme to WebDynpro Components
for creation of THEMS please refer these Documents
