Call a Portal Application from WebDynpro

Hi experts,
i hope you can resolve my problem!
My intention is to refresh the browser and call the first page of the portal after the portaluser pressed a button in an WebDynpro application.
For this purpose i create a portal application with an JSPDynPage and an JSP how call the JavaScript Method "top.location.reload();".
My question:
How can i call an portal application in a WebDynpro onAction Event?
Thanks,
Florian

1)Creat one action method "ReactPortalEventing" with the parameter dataObject and write the code in wdDoInit method as
//the urn and method name like "sendEvent" both should be same
WDPortalEventing.subscribe("urn:com.abc.practice","sendEvent",wdThis.wdGetReactPortalEventingAction() );
2)and in the action method display the name as
wdComponentAPI.getMessageManager().reportSuccess("Event value"dataObject);
also chk it

Calling a portal page from WebDynPro ABAp application

Hi,
I would like to call a portal page (any type) from a WebdynPro ABAP application. I have the PCD location of the page.
Which call shall I make :
Absolute Navigation
Relative Navigation or
OBN.
Also, can anyone send me short code snippet on the following.
The package SWDP test examples are not working.
Best Regards
Sid

Hi Siddharth,
Well, to start with you can go for ABSOLUTE NAVIGATION.
Secondly, you can find the snippet here
DATA LO_API_COMPONENT TYPE REF TO IF_WD_COMPONENT.
DATA LO_PORTAL_MANAGER TYPE REF TO IF_WD_PORTAL_INTEGRATION.
DATA L_NAVIGATION_TARGET TYPE STRING.
LO_API_COMPONENT = WD_COMP_CONTROLLER->WD_GET_API( ).
LO_PORTAL_MANAGER = LO_API_COMPONENT->GET_PORTAL_MANAGER( ).
MOVE 'pcd://portal_content/com.xxxx.zpof_f_XXXXportalcontent/com.xxxx.test/com.xxxx.folders.MaintenanceBusinessPackage/com.xxxx.test.mt.pages.Pages/com.xxxx.pages.MaintenanceTasks'
    to l_navigation_target.
CALL METHOD lo_portal_manager->NAVIGATE_ABSOLUTE
    EXPORTING
      NAVIGATION_TARGET   = L_NAVIGATION_TARGET
*      NAVIGATION_MODE     = IF_WD_PORTAL_INTEGRATION=>CO_SHOW_INPLACE
*      WINDOW_FEATURES     =
*      WINDOW_NAME         =
*      HISTORY_MODE        = IF_WD_PORTAL_INTEGRATION=>CO_NO_DUPLICATES
*      TARGET_TITLE        =
*      CONTEXT_URL         =
*      POST_PARAMETERS     = ABAP_FALSE
*      USE_SAP_LAUNCHER    = ABAP_TRUE
*      BUSINESS_PARAMETERS =
*      LAUNCHER_PARAMETERS =
Above it, the examples of SWDP will not work if you test them from SE80-ABAP WAS...I suggest you to create a WDA IView in Portal and test it in Portal itself.
Hope this should solve your problem.

Calling an Portal iView from Webdynpro - Error

Hi,
I have two iViews in a page in my Portal. Both of them are WebDynpro iViews.
The iView on the Left hand side consists of links to different WebDynpro iViews in the same Portal.
I have used LinkToAction UI element, on event of click
i am executing this piece of code.
onActionClick (com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent)
WDPortalNavigation.navigateAbsolute("ROLES://portal_content/folders/X.Iview", WDPortalNavigationMode.SHOW_INPLACE, (String)null, (String)null, WDPortalNavigationHistoryMode.NO_DUPLICATIONS, "Called iView Name", (String)null, (String)null);
I have picked up the iView name from the Portal(exact PCD location).
This is not giving me consistent results.
Please let me know your thoughts.
Thanks
Senthil

Hi,
Had some permission issues in the loading iView, got that sorted. Now it works fine.

Calling POWL Application From Webdynpro

Hi Experts,
I have a requirements wherein I have to call a POWL application from Webdynpro. Please let me know how to achieve this.
POWL - Personal Object Work List
Any help is welcome.
Thanks
Divakar

Hello Diwakar,
Based on your query i understand that you need to embed your powl into a web dynpro application to view it.
u can do it in two ways..
the first one is just for testing..
prerequisites...
just check ur web dynpro service is activated.
Use transaction SICF
On the Maintain Service screen leave the default values as they are and choose Execute
In the Virtual Hosts/ Services tree control locate the node sap/bc/webdynpro. Right click on
the node and choose Activate Service from the context menu.
1. Navigate to the initial screen of the SAP Easy Access Menu.
2. Do a right-click on Favorites and choose Add other objects from the context menu.
3. Choose Web Dynpro Application from the upcoming dialog box list.
4. On the Web Dynpro Application subscreen, make the following entries.
Web Dynpro Applicat.-->POWL
Parameter -> APPLID   (Be sure to select the parameter via input help.)
Value ->Specify the APPLID defined for the POWER List to test.
Leave rest unchanged.
click OK.
By double-click on the created favorite, the specified POWER List will be displayed in a separate
Browser window..Only the basic functionalities can be tested this way.
The second way is in which you manually insert a powl component in web dynpro appl..
1. create a web dynpro component.
2. Specify POWL_UI_COMP as the used component in the properties and give a suitable name.
3. In the main view. insert a ViewcontainerUIelement.
4. In the component controller properties . click on create controller usage. and select POWL_UI_COMP
INTERFACECONTROLLER
5. Go to the windows selection and right click and select embed view on the ViewcontainerUIelement of the Main view. select POWL_MASTER from input help.
6. Create an outbound plug , name it as 'OUT'. link it with DEFAULT plug by dragging.
7.Go to the methods tab and in the Handle Default method .
and paste the following code..
DATA: lv_inbox_query TYPE string,
        lt_query_params TYPE rsparams_tt,
        lwa_param TYPE rsparams.
DATA lv_qname TYPE POWL_QUERY_TY.
lv_qname = 'QUERY1'.
CALL FUNCTION 'POWL_ENCODE_SELPARA'
    EXPORTING
      i_selpara        = lt_query_params
      i_escape         = '\'
    IMPORTING
    e_selpara_string = lv_inbox_query .
    wd_this->fire_out_plg(
      applid = 'POWLappl'                          " powl_applid_ty
      forallq =   'X'                        " powl_xflag_ty
      qselpara =   lv_inbox_query                       " string
      refresha =   'X'
      refreshq = 'X'                    " powl_xflag_ty
      srvgroup =   'X'
      qname =    lv_qname                " rzlli_apcl
where QUERY1 is the name of your default query and POWLappl is your powl applid.
7. create application and test

Calling Webdynpro Java Application from Webdynpro ABAP Application.

Hi,
We have developed one Application using Webdynpro Java and I m in need to call the Webdynpro Java application from Webdynpro ABAP.
Require Suggestions to acheive this.
Thanks In advance.
Reg,
Ajay.

Dear Ajay,
Assuming that both your applications WDA & WDJ are in the portal & you don't have to pass any parameters to the WDJ application.
Write the following code on the action where you would call the WDJ application.
DATA:
        lr_compcontroller TYPE REF TO ig_componentcontroller,
        l_component TYPE REF TO if_wd_component ,
        lr_port_manager TYPE REF TO if_wd_portal_integration ,
        wa_navigation TYPE navigation.
lr_compcontroller =   wd_this->get_componentcontroller_ctr( ).
l_component = lr_compcontroller->wd_get_api( ).
lr_port_manager = l_component->get_portal_manager( ) .
* The value inserted into the navigation-target field can be found in the Portal
* content administration tab of your portal. It is the ID or PCD Location field
wa_navigation-target = pcd. " Please provide the PCD Location of the WDJ Application here.
wa_navigation-mode   = '0'. "0 = INTERNAL(same page) and 1 = EXTERNAL(new page).
CALL METHOD lr_port_manager->navigate_absolute
    EXPORTING
      navigation_target = wa_navigation-target
      navigation_mode   = wa_navigation-mode.
You can get the PCD from the Page properties of the WDJ application page in the Portal.
Hope it helps!
Warm regards,
Upendra Agrawal

Calling a Portal Service from within a Web Dynpro DC

Hello,
I am trying to call a Portal Service from within a Web Dynpro development component without sucess.
Can anyone give me some hints on the necessary steps in order to accomplish this task?
Thanks
Diz

Hi Diz,
I tried doing the same thing by following the steps as mentioned by you. Just to re iterate,
1. Created a DC "Portal Application Standalone" project by the name myservice.
2. Created a portal service inside myservice by the ame AmitsService.
3. Exposed IAmitsService.class in the public part.
4 Build and deployed the DC on server and tested it through an abstract portal component and it worked FINE !!
Now..
5. Created anoter DC of type WebDynPro
6. Added SAP_JTECHS -> epbc.prtapi._api as a "Used DC" with dependency build time and runtime
7. Specified the sharing reference in the properties as PORTAL:sap.com/myservice
8. Tried to reference the service using the following code..
IAmitsService portalservice=(IAmitsService)WDPortalUtils.getServiceReference(IAmitsService.KEY);
9.Build and deployed the DC.
10. When I run the application I am getting the following error
Processing HTTP request to servlet [dispatcher] finished with error.
The error is: com.sap.engine.frame.core.load.SAPNoClassDefFoundError: com/sapportals/portal/prt/service/IService

Calling an EJB application in webdynpro

Dear SDN's,
I am trying to call an EJB application from a webdynpro application and is succeded in storing values to database via Java Bean Model.
I want to retrieve all records from table via EJB and all the records should be displayed in Webdynpro Table UI element.
How can we do it?
The problem here is, how to return a set of records to webdynpro from EJB via a javabean.
I am not clear in using Collection Framework! i.e, which collection class i have to use to store the retrieved records.
Your help will be appreciated.
Regards,
Sireesha.B

Hi Sireesha,
Instead of adding resultset, create a EMP cinstance and add it.
Ex : Consider you have created a EMP class
class EMP
String empname;
int id;
public void setEmpname(String name);
public String getEmpname();
Now
ResultSet rs=statement.executeQuery(select * from emp);
Vector v=new Vector();
while(rs.next)
Emp e=new EMP()l
e.setEmpName(rs.getString(0));
e.setID(rs.getInt(1)));
v.add(emp);
Iterator i=v.iterator();
while(i.hasNext())
Emp e1=(EMP)i.next()l
System.out.println(e1.getempName());
System.out.println(e1.getID);

How to call an applescript application from Office 2011 Excel VBA

All:
I have been pounding my head how to implement a working VBA application into the Mac environment. I have tried a number of approaches calling applescript from VBA. I would like to call my applescript application and pass one argument. My applescript application is as follows:
<code>
on run argv
set theURL to (item 1 of argv)
set p_path to do shell script "echo ~"
set m_path to POSIX file p_path
set theName to text -((offset of "/" in (reverse of characters of theURL) as text) - 1) thru -1 of theURL
set theFile to (p_path & "/Downloads/" & theName)
set macPath to (POSIX file theFile)
do shell script "/usr/bin/curl " & theURL & " -o " & quoted form of POSIX path of macPath
end run
</code>
My last attempt within VBA is:
<code>
Sub SaveMetaDataFile(URL As String, shortFileName As String)
Dim scriptToRun As String
Dim posixcmd As String
posixcmd = ThisWorkbook.Path
scriptToRun = "tell application " & posixcmd & ":MetaDataFileDownloadScript.app " & URL
MsgBox "[" & scriptToRun & "]"
MacScript (scriptToRun)
</code>
I first tried to call the script directly without the "tell application" and I still obtain an error. I also tried the following in VBA and I get the same error with the last lane of code:
<code>
scriptToRun = "set theURL to " & """" & URL & """" & Chr(13)
scriptToRun = scriptToRun & "set p_path to do shell script " & """" & "/bin/echo ~ " & """" & Chr(13)
scriptToRun = scriptToRun & "set m_path to " & """" & posixcmd & """" & Chr(13)
scriptToRun = scriptToRun & "set theName to " & """" & shortFileName & """" & Chr(13)
scriptToRun = scriptToRun & "set theFile to (p_path & " & """/Downloads/""" & " & theName)" & Chr(13)
scriptToRun = scriptToRun & "set macPath to (POSIX file theFile)" & Chr(13)
scriptToRun = scriptToRun & "do shell script " & """" & "/usr/bin/curl " & """" & " & " & " theURL " & " & " & """" & " -o " & """" & " & " & " quoted form of POSIX path of macPath"
MsgBox scriptToRun
'scriptToRun = scriptToRun & "do shell script " & """/usr/bin/curl """ & " & " & " theURL " & """ -o """ & " & " & " quoted form of POSIX path of macPath"
MacScript (scriptToRun)
</code>
The above code is from the applescript application. The applescript application works well using the terminal via osascript. For example:
xenas-imac:Census Work Xena$ osascript MetaDataFileDownloadScript.app http://www2.census.gove/acs20095yr/summaryfile/Sequence_Number_and_Table_numberLookup.xls
xenas-imac:Census Work Xena$
The whole goal is to download a file into the Download directory from Excel to allow the next step to import the file into Excel for the user. Any help here would be great!
Thank you;
Lori

Update:
Ok have the module almost working and matches the syntax within the test applescript I had created, but the VBA code via the MacScript() call is generating an invalid procedure or argument call. The following is the test applescript to compare the created string to be passed to VBA MacScript() function:
<code>
set appPath to quoted form of POSIX path of "Macintosh HD:Users:Xena:Desktop:Census Work:"
do shell script "/usr/bin/osascript " & appPath & "MetaDataFileDownloadScript.app " & "http://www2.census.gove/acs20095yr/summaryfile/Sequence_Number_and_Table_numberLookup.xls"
</code>
The following is the VBA module that generates the above word for word as far as I can tell:
<code>
Sub SaveMetaDataFile(URL As String, shortFileName As String)
Dim scriptToRun As String
Dim posixcmd As String
posixcmd = ThisWorkbook.Path
posixcmd = posixcmd & ":"
scriptToRun = "set appPath to quoted form of POSIX path of " & Chr(34) & posixcmd & Chr(34) & Chr(13)
scriptToRun = scriptToRun & "do shell script " & Chr(34) & "/usr/bin/osascript " & Chr(34) & " & appPath & " & Chr(34) & "MetaDataFileDownloadScript.app " & Chr(34) & " & " & Chr(34) & URL & Chr(34)
MsgBox "[" & scriptToRun & "]"
MacScript (scriptToRun)
End Sub
</code>
The message box in the above VBA code matches my test applescript file and I have taken the output of the MsgBox and used it in a test applescript and it works great, but VBA is throwing "Run-time error '5': Invalid procedure call or argument".
Looking at Microsoft's definition it takes a string argument and I have made sure that scriptToRun is a string type, so at this point I suspect there is something wrong with the MacScript() funciton, or I am missing something above. Is there another way to call an applescript application from VBA outside the MacScript() function? Or is there something I am missing? Any help or suggestions is needed.
Thank you;

Call a Java Application from MicroFocus COBOL (in UNIX environment)

Hello,
Could you please let me know, how to call a Java application from a MicroFocus COBOL application. If anyone has any code samples, that would be of great help.
Thanks in advance,
Tijo.

You generally can't cause a program to be executed on a different >server. Basic security, you know. Besides this idea of having the Java >application run on a different server wasn't mentioned in your original >post. That leads me to believe we don't have the whole story.So I think you need to step back and find out what are the requirements. For example: Does your program need to start this Java application running, or is it already running and your program needs to connect to it somehow?
My program has to start a Java class file, meaning that the Micro Focus COBOL module will call the Java class file. Will it be running on the same machine as your program, or on some other machine?
For both cases, I would like to know the answer.a) Running on the same machine as my program is running.
b) Running on the different machine.
And then there are the questions about whether your program needs to have a conversation with the Java application, or whether it just needs to start it and that's all.
COBOL program has to call a Java class by passing some parameters and Java class in turn process it and return some value back.. Kind of Request and Response model.Plenty of questions to be asked. Go and find out what they are.
Sorry ... if I am not clear on my questions. Anyhow, thank you very much for providing the information.

Calling a java application from j2ee web application

Hi,
I have a j2ee application in which i am making a call to a jar file which is a java application.
Runtime a4 = Runtime.getRuntime();
Runtime a = Runtime.getRuntime();
String cmd[] = new String[14];
cmd[0] = "cmd";
cmd[1] = "/c";
cmd[2] = "start";
cmd[3] = "javaw";
cmd[4] = "-jar";
cmd[5] = CATALINA_HOME+"\\webapps\\AveksaTesting\\AveksaTestingJava\\dist\\AveksaTestingJava.jar";
cmd[6] = SERVER_TESTS;
cmd[7] = COLLECTOR_TESTS;
cmd[8] = SYSTEM_TESTS;
cmd[9] = CREATE_ORACLE;
cmd[10] = DB_NAME;
cmd[11] = DB_DUMP;
cmd[12] = email;
cmd[13] = isMIGRATE;
try{
java.lang.Process p = a.exec(cmd);
Now in the called java application, i am first shutting down the tomcat server by calling shutdown.bat script and then starting it using startup.bat. But the problem i am facing is when i restart the server from java application, it says address already in use(i.e. port 8445 on which tomcat is runninng).
Id i just call the java application and do the same operation it works fine. I guess when i am calling java from j2ee application, j2ee still has some threads holding java and not shutting down tomcat properly.
Can anyone suggest me what can be done in this case. I have to call a java application from j2ee and restart the tomcat server many times.
Thanks in advance
