Dynamically Calling a built-in API Class

Ok...
Scenario:
I'd like to pick between an internal pdf viewer and an external using the java.awt.Desktop class.
Unfortunately, for development purposes, I need the code to compile on Java 1.5 (1.5 doesn't have java.awt.Desktop)
Eventually we'll move to 1.6, but until we do, the other contributors don't want to be bothered with commenting out the 1.6 code.
I figured I could dynamically load the class with:
Class.forName("java.awt.Desktop")or perhaps
Class.forName("java.awt.Desktop").newInstance()The Desktop class complains about modifiers "private".
I tried calling the Desktop.open method directly with:
Class.forName("java.awt.Desktop").getDeclaredMethod("open", new Class[]{java.io.File.class};).invoke(null, pdfFile);With no luck either.
I'm compiling on Java 1.6, with the hopes that the 1.5 compilers won't complain. Is this possible, or am I trying to do something outside the scope of Java?

Hey guys, this WORKS! Infact, the compiled Java 1.5 version flawlessly opens the application with our 1.6 clients!
I'm pretty impressed that java has this flexibility! Thanks all!
Here's my exact code. I had to remove a few nulls to supress warnings.
try {
        desktopCall("open", new File("C:\samplefile.pdf"));
catch (Exception e) {
        // Open w/ internal viewer
public static void desktopCall(String call, Object o) throws Exception {
     Class[] f = new Class[]{java.io.File.class};
     Object obj = Class.forName("java.awt.Desktop").getDeclaredMethod("getDesktop").invoke(null);
     Class.forName("java.awt.Desktop").getDeclaredMethod(call,f).invoke(obj,o);

Binding parameters to dynamic VO with PL/SQL API call with no where clause

Hi all,
I am required to change exisiting queries to queries with "bind" parameters. Some of our VOs are dynamic and with PL/SQL api calls like below:
String stmtStr = "selectXXX_API_UTILS.chk_urg_since_last_prg("
+ projectId + "," + PPCId + ",'XYZ_TASKS'," + taskId+ ")"
+" from dual ";
ViewObject tmpVO = transaction.createViewObjectFromQueryStmt(stmtStr);
In this regard, I am unsure how to bind the PPCId and taskId parameters to the VO. setWhereClauseParams() would not work here as there is now where clause.
Thanks in advance,
Srini

In case of preparedStatement, we mention bind parameters to be passed using "?". Then we pass paramters sequencially.
But in the your case following is enough:
int projectId = 100 ; (hardcoding values for example)
int taskId = 500 ;
String stmtStr = "selectXXX_API_UTILS.chk_urg_since_last_prg("
+ projectId + "," + PPCId + ",'XYZ_TASKS'," + taskId+ ")"
+" from dual ";

Calling Portal event from ABAP class

Hi Experts,
I need a following clarificatrion, Please help,
1. Is it possible to call a webdynpro method from a normal ABAP class?
2. If no, we need a functionality of a class 'CL_WDR_HTTP_EXT_MIME_HANDLER' having method 'DO_DOMAIN_RELAX_HTML'.
Is there any alternative method which can be used in ABAP having the same functionality.
3. Is there any ways with which we can call portal event from ABAP class?
Thanks,
Shabir

>1. Is it possible to call a webdynpro method from a normal ABAP class?
I wouldn't necessarily recommend this approach. You shouldn't try to trigger events or any of the standard WDDO* methods from outside the WD Component itself. That said, you can pass the object reference (like the WD_COMP_CONTROLLER object reference or the View Object Reference) into methods of normal classes. Be careful if you are finding yourself calling a lot of your added methods from outside WD. This is probably a sign that these methods should be in the Assistance Class or some other Class functioning as a Model Object.
>2. If no, we need a functionality of a class 'CL_WDR_HTTP_EXT_MIME_HANDLER' having method 'DO_DOMAIN_RELAX_HTML'.
Is there any alternative method which can be used in ABAP having the same functionality.
What exactly do you want to do here? Do you just want to get the relaxation script? For what purpose? You should never need to inject the relaxation script into WDA.
>3. Is there any ways with which we can call portal event from ABAP class?
To what purpose. Do you just want to delegate the triggering of the event that is inside WD Component to be called from a class? If so you can pass the portal API object reference into a class from the WD Component. However this only works while running within WD.
How is this class used? Are you running in WD? Are you trying to generate some HTML code that runs in the portal independent of WD?

Dynamic call of a static method of an static attribute

Hi all,
is it possible to call dynamically a static method of a static attribute of a class.
The statement without dynamic call would look like this:
cl_test_class=>static_attribute=>static_method( ).
I would like to do it like this:
('CL_TEST_CLASS')=>static_attribute=>static_method( ).
Netiher the one nor the other way works for me - I'm getting the error "The notation used is reserved for business object classes".
Regards, Stefan

I guess, it is not possible to call method using the short form (parameters in brackets) is not possible in Dynamic Access. You may need to get the attribute first and then call the method.

How to parse a string in CVP 7.0(1). Is there a built-in java class, other?

Hi,
I need to parse,in CVP 7.0(1), the BAAccountNumber variable passed by the ICM dialer. Is there a built-in java class or other function that would help me do this?
Our BAAccountNumber variable looks something like this: 321|XXX12345678|1901|M. In IP IVR I use the "Get ICM Data" object to read the BAAccountNumber variable from ICM and then I use the "token index" feature to parse the variable (picture below).
Alternately, IP IVR also has a Java class that allows me to do this; the class is "java.lang.String" and the method is "public int indexOf(String,int)"
Is there something equivalent in CVP 7.0(1)?
thanks

Thanks again for your help. This is what I ended up doing:

Runtime error OBJECTS_OBJREF_NOT_ASSIGNED when calling any standard GRC API's

Hello colleagues,
I always get the runtime error OBJECTS_OBJREF_NOT_ASSIGNED when calling any standard GRC API's
For instance, lets take Function Modules:
I tried almost any of them but in particular:
GRPC_API_CONTROL_QUERY Load the list of controls
GRPC_API_ISSUE_QUERY Retrieve issues of the case
GRPC_API_ORGUNIT_QUERY Load list of Organizations
GRPC_API_RMPLAN_QUERY Retrieve remediation plans of case
GRPC_API_RISK_CONTROLS Retrieve the controls of the risk
and etc.
All of them return the runtime error OBJECTS_OBJREF_NOT_ASSIGNED, however I've provided Object ID's in the right format,
The same is for corresponding classes,
Does anyone have such problem before?
Appreciate your responses,
Thank you,
Best Regards,
Anton

Hi Anton,
We need to pass value for I_SESSION_ID. Because, when i execute FM: GRPC_API_RMPLAN_QUERY by giving correct I_OBJECT_ID as shown below, i'm also getting the same error.
On executing..
Getting following dump.
And attached is the dump analysis .
Thanks

Calling BO(Business Objects API ) from my J2EE Application

We have an application which contains a module that handles
User Creation and Maintenance.
Right now we have New and Authorize screens.
Basically these users can access reports in BO.
But this user creation in BO(Bussiness Objects) is done manually in BO.
Now I need to automate this user creation in BO from my UserMaintenance Module.
BO has exposed an API thru which we can call functions to create an User in BO.
My problem is where to call this API from ?We call a stored procedure for authorizing a new user in UserMaintenace Module.
We use Struts Framework.
Action class--->ServiceClass-----> DAOClass
In this DAO class we call this stored procedure to authorize the user creation.
My question is where to call this API from .
That is ,it should be called from DAO or ACtion class or Service class.
How to call an external API and what are the issues that are generally involved in calling an external API.
Fortunately both my weblogic and BO servers reside on the same unix server.
While calling an API should I have to take care about Portnumbers,external machine location i.e host address,
How to handle database connection.
Can someone throw an answer to these questions.
Thanks in advance

As I understand, your user management is through database, so when a user is created in your application, the parameters pass through the Action Handler -> service class-> DAO. So a better way would be write an additional class with the user management implementation of BO with a constructor or a method which would take the required user creation parameters and call it in the service class just under the user creation method of your DAO.
As the user in your system passes some information from the front end, the same can be used to create user in BO.

Dynamical Call of ALV - No data update

Hi,
I tried to use use the ALV dynamically. With dynamically I mean that I that I have diffrent data structures, depending what was selected by the user. The first call of the program is always correct. The data is displayed correctly. But when the data structure is changing, the ALV display is not updated. For a better understanding I post a extract of my coding:

Best Regards, Edgar

Hello Edgar
The following sample report ZUS_SDN_TWO_ALV_GRIDS_8 shows how to solve your problem. Please note that for the sake of simplicity I replaced the tree containing the structure names with an ALV list. However, the switch between the different structures is triggered by the DOUBLE_CLICK event.
I like to add that the integration of the first displayed ALV list (DD02L) into GT_OUTTAB is not really elegant. In addition, with $TMP I marked a problematic part of the coding with respect to your requirement to have the right layout for each displayed ALV list:
If you have a fixed assignment of tabname -> 4-digit handle then it is ok. I my sample report the layouts only work if you select the tabnames in the very same order.
Before showing the entire coding I describe crucial parts of the coding:
[code]TYPES: BEGIN OF ty_s_outtab.
TYPES: tabname TYPE tabname.
TYPES: layout TYPE lvc_s_layo.
TYPES: variant TYPE disvariant.
TYPES: fcat TYPE lvc_t_fcat.
TYPES: data TYPE REF TO data.
TYPES: END OF ty_s_outtab.[/code]
Every time a new structure is selected the corresponding ALV data are stored as new record in GT_OUTTAB which is of line type TY_S_OUTTAB.
[code] READ TABLE gt_outtab INTO gs_outtab INDEX 2.
ASSIGN gs_outtab-fcat TO <gt_fcat>.
ASSIGN gs_outtab-data->* TO <gt_outtab>.[/code]
Since the ALV list data and the fieldcatalog are fully dynamic I use global field-symbols for these data.

The second ALV list which displays the table records is always newly displayed in the PBO module.
In the event handler method HANDLE_DOUBLE_CLICK we need to do two things:
- store the current fieldcatalog back to GT_OUTTAB
- store the name of the new selected table/structure -> trigger PAI
In routine HANDLE_DB_CLICK we create a new entry for GT_OUTTAB if it does not yet exist. Next we select this entry and display it again as second ALV list.

Dynamically calling EJBs

Hello,
I'm reasonably new to working with EJBs so perhaps this isnt possible... Can you dynamically call an EJB at runtime ie like reflection.
I know once the bean has been created I can use reflection to call the method but how can I create the bean from the beans remote home interface?
Many thanks
Michael

Got it
EJBMetaData md = theHome.getEJBMetaData();
Class homeClass = md.getHomeInterfaceClass();
EJBObject theRemote = (EJBObject)invoke(homeClass,theHome,"create");
static Object invoke(Class c,Object obj,String mname){
 Method[] methods = c.getMethods();
 String name=null;
 Object r= null;
 try {
 for(int i = 0; i<methods.length ;i++) {
 name = methods.getName();
if(name.startsWith(mname)) {
r = methods[i].invoke(obj,null);
} catch(Exception e){
e.printStackTrace();
return r;

Dynamic calls from executable

Hi all,
I used to have LabVIEW application, as executable, which does dynamic calls to any VI. Until now it was done and built with LV2009 and worked fine as long as the vi.lib folder was copied to same of folder than the executable (this was needed for dependencies).
I've now moved to LV2012 and my application does not work anymore. It seems that dynamically loading any VI in vi.lib which calls an LLB is not possible and leads to an error. Is this known ? Is it a bug or a new limitation in LV2012 ?
Thanks,
Alex

Here is how to reproduce this issue :
First, open the attached GetVIDependencies.vi in the LV2012 development environment. In the "VI Patch" field, enter the path of the attached "Test.vi" and then execute the VI.
You should get 38 found dependencies and 0 missing. Then do the same with the exe version of GetVIDependencies. You should get 1 dependency which is missing. This is normal because the runtime does not know where <vilib> is placed. If you place the exe in the LabVIEW.exe directory (where vilib stands), you will get the same result.
Then, if you have LV2009, try the same with the 2009 executable version and "Test_LV2009.vi". It will work as soon as you place the executable in the LabVIEW.exe (2009) folder, no matter where "Test_LV2009.vi" is placed.

How to debug dynamic calls

Hi Gurus,
Can any one tell me how to debug dynamic calls?
The scenario is:
I know the message that is getting fired from a message class.
I didnot find its usage from the where-used list, as it says - possible dynamic calls.
How do i know, from where this message is getting fired?
Pls suggest.
Thanks, Rashmi

Hi,
Just try this
In the new debugger Breakpoints --> Breakpoint at --> Breakpoint at Statement
give MESSAGE
This will set break point at all message statement. Execute till you get the message

Return data is null while calling Exchange Online rest api using jquery on Chrome and Mozilla

Hi,
I am developing a SharePoint hosted app in which I am calling Exchange online rest api using basic authentication to get mail for the user. This works fine in IE but returns null data when opening in Chrome or Mozilla.
Is there something I am missing while making rest call to api?
Please remember to mark your question as answered &Vote helpful,if this solves/helps your problem. Thanks, Ajeet

Hi,
This forum is to discuss problems of Office development such as VBA, VSTO, Apps for Office .etc. But I think your question is related to app for SharePoint. I suggest you posting it in

Two remote objects calls on the same php class

Hi to all,
I've encountered a strange issue while developing with remote objects.
I've a mxml component with an init() method inside which is called by a menu.
When the init() method is called it makes 7 remote object calls which are bound to some components' dataprovider.
Among this calls I've got 2 remote object which refer to the same remote class. This because I have to call the class twice and the bind the result to two different combobox. Below you find the code:
<mx:RemoteObject id="myFile" source="myRemoteClass" destination="amfphp" showBusyCursor="true" makeObjectsBindable="true" fault="traceFault(event)"/>
<mx:RemoteObject id="myXls" source="myRemoteClass" destination="amfphp" showBusyCursor="true" makeObjectsBindable="true" fault="traceFault(event)"/>
in the init function I make this calls:
myFile.listDir("dir_1")
myXls.listDir("dir_2")
then in the mxml code I bound the result of myFile to combobox1 and the result of myXls on combobox2.
The problem arise when I call the myXls' listDir method. When I call it I receive the following error:
code:
Client.Error.DeliveryInDoubt
Message:
Channel disconnected
Detail:
Channel disconnected before an acknowledgement was received
The strange thing is that not only the myXls object returns this error, but also all the other 6 remote object return the same error above.
I'm not sure, but I guess that the error could be caused by the two remote object which call the same php remote class. If I comment one of the two calls everything works fine.
Do you have any suggestion about?
Thanks!!
Bye
Luke

Hi Jan.
1) We have the 2 VO, each with 3 rows to fill in data. What I mean is that when i just fill in all the fields for the first row of the first VO, and the value of one of these fields is bigger than 50, then after the exception is thrown and the message is displayed, the fields for the first VO are duplicated and shown in the second VO as if the user had inserted them.
2) We tried yesterday the validateEntity and a Method and Atributte Validator approaches after reading that white paper with the same results.
The validation is correctly done using any of the those methods.
I will try to reproduce this issue with the HR schema.
Thanks in advance once again.
