Accessing COM/ATL objects

Hi,
I need to access COM/ATL objects from a java application (to be run only on Windows), and I'm having a very difficult time finding how to do it.
Can anyone offer any insight?
Thanks

Hi,
Usually, the best approach would be to just to load the resources as InputStream and have a catalog (and I know this is what you do not want to do :-) So the only hacky workaround that I can think of would be to use something like Jakarta Commons Virtual File System (http://jakarta.apache.org/commons/vfs/) and read the .zip

You can use Call Library Function node to call that dll file and use it in LabVIEW. Read the help and you will get more details.

Adobe Plugin not able to access COM object in Protected mode

We have an adobe plugin for our application. The plugin creates a toolbar button in Adobe and on clicking this button, it invokes one of the form from our application to save the document record for the PDF file in the database. The plugin was working fine till Adobe 9. It stopped working in Adobe X with proctected mode ON. However, if we turn off Protected mdoe, it works fine.
I did some research and found that we need to modify the policy rules by creating ProtectedModeWhitelistConfig.txt file and appropriate registry for it. I did those steps and now I am not getting "Access denied" error when protected mode is ON but the plugin is still not working. On further debug, I found that it fails while trying to connect to SQL Server. It gives error "SSL Security Error". This is working perfectly fine without protected mode. Also It is not able to access COM objects. I guess both these things might be related.
Can anyone let me know what are we missing here?

I would recommend that open a formal support case, as working with Protected Mode is quite complex.

Problem with Dynamically accessing EJB Class objects in WL 7.0 SP1

I am trying to build a component which has the ability to instantiate and execute
an known EJB method on the fly.
I have managed to build the component but when I try and execute it I get a ClassNotFoundException.
I know that the EJB I am trying to invoke is deployed and available on the server,
as I can see it in the console, I also seen to have been able to get the remote
interface of the object, my problem occurs when I try and access the class object
so I can perform a create on the object and then execute my method
The code I have written is below:
private Object getRemoteObject(Context pCtx, String pJNDIName, String pHomeBean)
throws Exception {
     String homeCreate = "create";
     Class []homeCreateParam = { };
     Object []homeCreateParamValues = {};
try {
//This call seems to work and doesn't throw an exception
Object home = pCtx.lookup(pJNDIName);
//However this call throws a java.lang.ClassNotFoundException
Class homeBean = Class.forName(pHomeBean);
Method homeCreateMethod = homeBean.getMethod(homeCreate,homeCreateParam);
return homeCreateMethod.invoke(home, homeCreateParamValues);
} catch (NamingException ne) {
logStandardErrorMessage("The client was unable to lookup the EJBHome.
Please make sure ");
logStandardErrorMessage("that you have deployed the ejb with the JNDI
name "+pJNDIName+" on the WebLogic server ");
throw ne;
} catch (Exception e) {
logStandardErrorMessage(e.toString());
throw e;
Any advice would be really appreciated, I'm fast running out of ideas, I suspect
it has something to do with the class loader but I'm not sure how to resolve it

Hello Joanne,
Congratulations! I'm very happy that you've managed to fix your problem. It's
always essential to understand how to package applications when deploying on BEA
WebLogic. Usually, by throwing everything into an EAR file solves just about all
the class loader problems. :-) Let us know if you have any further problems that
we can assist you with.

Hello Joanne,
As Mr. Woollen mentioned, I also believe it's a problem with the class

You need to be careful how you arrange your EJBs, because WebLogic has
a specific
method in which it loads classes in an EAR, JAR, and WAR file(s). Please
refer
to http://dev2dev.bea.com/articles/musser.jsp for more information about
BEA WebLogic
class loading mechanisms and caveats. Also, try printing out the various
methods
that are available on the object that was returned to you via reflection.
For
example, use the getMethods() method, which returns an array of Method
objects
that you can subsequently cycle through and print out the various method
names.
This way you can discover if the class found/returned to you is indeed
the one
you intend to locate.
Hope this helps,

If you do:

Are the EJBs that you are trying to access accessible via your
system
classpath?
Try to avoid having them accessible via the main system classpath,and
only bundle
them in your appropriate EJB jar files (contained in an EAR file,for
example).Maybe I should have laid the problem out a little clearer.
I have a number of EJB's bundled up in a JAR file which is hot deployedto
the
server. Within this first JAR file is an EJB (SSB) component that
needs
to
be
able to invoke a known method on another EJB. This second EJB may
or
may
not be
within the first JAR file but it also will be hot deployed.
The component trying to invoke the method on the 2nd EJB has to
be
able to
create
an instance of the 2nd EJB without actually knowing anything bar
a
JNDI
Name which
is passed in at runtime.
I can get as far as doing the
Object home = pCtx.lookup(pJNDIName);
This returned a class with the name
"com.csc.edc.projects.allders.httppostoffice.postman.PostmanBean_mp8qy2_Home
Impl_WLStub"
My problem seems to occur when I try and invoke the create method
Method homeCreate = home.getClass().getMethod("create", new Class[0]);
My code throws a java.lang.NoSuchMethodException at this point so
I
am
unable
to progress to the next step of :
Object bean = homeCreate.invoke(home, null);
So I can return the instantiated bean back to the calling client.
Why am I getting the NoSuchMethodException, is is because I am gettinga
stub
back rather than the home interface and if so how do I get the truehome
interface
from the bean

Hi experts,
I have a component having context->node1->usernr
usernr is one of the attributes in node1.
node1 has cardinality 0..n
I have two views, view1 and view2 in the window.
both the view contexts have mapping with node1 of component controller context.
View1 has a table that shows usernr as a column and view2 has an inputfield, the value of which is bound to usernr.
On clicking a button in view1, I am creating an element of node1 and binding it to the node. this os working fine. Also I am firing the outplug of view1 which is connected to inplug of view2.
I debugged the view2 and it is going upto the HANDLEIN_view2_inputplug
Then I just get this dump "Access via 'NULL' object reference not possible."

The current ABAP program "CL_WDR_VIEW_ELEMENT_ADAPTER===CP" had to be terminated because it has come across a statement that unfortunately cannot be executed.
Error analysis
You attempted to use a 'NULL' object reference (points to 'nothing') access a component (variable: " ").
An object reference must point to an object (an instance of a class) before it can be used to access components.
Either the reference was never set or it was set to 'NULL' using the CLEAR statement.

Hey Reema,
Were you able to resolve this error. I am facing exactly the same issue currently . My primary data container nodes belong to the component controller. I did verify the same for any change in the cardinality and dont see anythign thats changed which could be impacting my views. In any case, I had kept the cardinality as 0...n initially to be safe since there cud be scenarios where no values can exist for the same at runtime.
Please do let me know how you happened to resolve this.

Imlementing synchronized access to shared objects in LabVIEW OOP

Many objects in object-oriented programming have an
identity, such as a file, a front-panel object or a hardware device.
These objects cannot be modelled using present LabVOOP (LabVIEW Object Oriented Programming) objects as
LabVOOP objects gets copied as wire is branched; multiple different
wires cannot all represent a single object. This issue has been
irritating the community of LabVIEW users since the release of LabVOOP
a few months ago.
It seems that there is a huge demand for
objects with unique identity i.e. by-reference objects in LabVIEW. The
central problem why LabVOOP propably doen't have these objects is the
difficulty in implementing synchronized access to these objects from
multiple parallel threads. The problem of synchronized access can be
divided into two different separate topics. First how the
sychronization should be implemented in LabVIEW runtime engine. Second
how this synchronization mechanism should be visible to the developer.
I'd like to start this thread to discuss these two issues.
Synhronization under the hood
Traditionally
people talk about locking of an object and about get-modify-set pass
when accessing the object. Locking is traditionally done by acquiring a
mutex for an object, modifying the object and releasing the mutex so
that other threads can access the same object instance. This is how
inter-thread synchronization is traditionally done. However, besides
the mutex based locking, the computer science community has innovated
also different kinds of methods on synchronizing the access to objects.
One way to get object-level synchronization is modify the
runtime engine so that it only allows a single method of a synchronized
object to run at any time. This mechanism of syncrhonization is
implemented in programming languages like O'Haskell, which is a Haskell
variant with object orirented features.
Also different
transactional mechanisms[1,2] have been successful. In transactional
mechanisms multiple threads are allowed to access a synchronized object
simultaneously. As each method accessing an object commits their
changes, they verify that no other object has modified the object
simultaneously in a manner than would break the transaction. If such a
modification has occurred, everything is rolled back. Transactional
mechanism do not suit to every possible situation as not everything can
be rolled back. For example it's hard to roll back an action that
somehow modifies the physical world.
User experience of synchronization
How
the synchronization is generally implemented in LabVIEW shouldn't be
directly visible to the developer end-user. The developer should
understand the general concepts of synchronization to take full
advantage of it, but in general the synhronization mechanism should be
integrated directly to development environment. There should in general
be no need to acquire a mutex by calling acquire mutex node but instead
the end-user should be able to specify which data needs synhronized
access in more sophisticated way.
In the following I propose a
mechanism of integrating the synchronized access of by-ref objects to
the development environemnt of LabVIEW. The proposal is very
preliminary but I hope it breaks the ice and the community would start
innovating in how should NI implement the syncrhonization support in
the user interface of LabVIEW.
Wire level synchronization
Only
methods can access object private data members. In synchronized access
to the object, it's the methods accessing the private data members that
need to be synchronized. The private data members are accessed by
applying unbundle node to the class wire and data is written back to
the object using bundle node.
What I propose is the following.
An unbundle node could either be normal or "synchronized". A
synchronized unbundle would guarantee the access to the private data
members in synchronized manner. All data wires originating from
synchronized unbundle would be of synchronized type, in a little
similar manner as a dynamic dispatch wire is of special dynamic
dispatch type. Such a wire must evetually be connected to a bundle
node. When the wire is bundled back to the originating object, the
synchronization requirement is released.
These synchronized
wires would look somewhat different from normal wires so that the
developer instantly knows that the wire is synchronized. The developer
can branch the wire, but only one wire branch can own the synchronized
type. The developer could easily select which wire would be
syncrhonized by Ctrl+clicking the wire. Such a wire can be considered
as a combination of a data and a mutex, even though mutexes don't need
to be the underlying synchronization method. The wire just guarantees
that there is a mechanism in the runtime engine that makes sure the
access to the wire data is synchronized.
There is a need to wire
data originating from a non-synchronized wire to a synchronized wire so
that it can replace the private data member of the class. This is
accomplished with a new node similar to bundle node, that would allow
replacing the data in a syncrhonized wire with some data originating
from a non-synchronized wire.
The synchronized wire can be
connected to a front panel controls of special syncrhonized type. This
way the synchronized wire can originate from a method and allow passing
the synchronized data to the calling VI and back to another method.
This is practical for example in a situation when the developer wants
to run different analyzes to a data class but don't want to rewrite all
the existing data analysis tools as class members. So the developers
writes a syncrhonization acquiring getData method that let's the
calling VI to access the syncrhonized data. Then the developer passes
this data to an analysis VI and passes the result back to a setData
method that writes the result back to the class wire.
There
will probably be technical problems in allowing the user to connect
such a synchronized wire to all existing VIs since these VIs. Therefore
the programming model for all nodes that do not support such
synchronized wires will be branching the wire and passing the
non-synchronized wire branch to the node and then bundling the result
back to the synchronized wire.
To increase performance and
decrease unnecessary buffer copies when a syncrhonized wire is
branched, if the syncrhonized wire continues directly to the new bundle
synchronized wire node, no buffer copy is made.
Discussion
The
syncrhonized access to a by-ref LabVOOP objects can be implemented in
multiple ways by National Instruments. The synchronized access should
be divided to two different and independent parts: 1) the user
experience of synchronization and 2) the runtime engine synchronization
mechanisms. As LabVOOP objects have special properties compared to
other LabVIEW data types, optimal user experience can be gained by
designing the user experience specifically for LabVOOP objects. From
user experience point-of-view this syncrhonization mechanism may not
work for other data types. Separating object syncrhonization from
synchronization of other data types is advantageous also for other
reasons. Due to the fact that object data can only be accessed via
object methods, more advanced synchronization methods may be used with
objects than can be used with other data types. O'Haskell
synchronization implementation is an example of this. Integrating the
synchronization directly to the user interface allows NI to change the
mehcanisms under the hood, when computer science comes up with more
advanced methods. Therefore NI could begin with traditional and quite
easy mutex-based synchronization and later move to more advanced
perhaps transaction based syncrhonization methods or even combinations
of multiple different methods.
I hope this topic generates
discussion that would help NI to implement an excellent synchronization
mechanism in LabVOOP. I hope that all talented individuals in the
community participate this discussion to help NI to reach this goal. I
also hope that if you just have time, it would be great if you could
surf the computer science resources to find out what kinds of new
techniques there exists for synchronizing access to shared resources. A
Large community may find much more innovative solutions than a few engineers at NI. Let's give NI the power of open source design
Tomi Maila

Hello Tomi,
First, thank you for taking the time to write such a well
though-out suggestion. Are you familiar
with the “LabVIEW Object-Oriented Programming: The Decisions Behind the Design”
document? I think the reason we chose to implement a ‘by
value’ strategy, is that is more in line with the LabVIEW programming paradigm
of dataflow, and would make sense to most of our LabVIEW users.
I think your suggestion is interesting, and it does
highlight the need to think outside of the conventional LabVIEW box and look to
some of the innovative things other languages do. However, I think we all agree that
synchronization takes careful planning and extra work for the programmer. Even with an ‘ideal’ solution I see no way
around this. For LabVIEW users today,
one great way to get synchronized ‘by reference’ semantics with your objects is
to use a single-element queue to pass your object. The queue itself is passed ‘by reference’ and
is inherently synchronized! The does
have the disadvantage of adding one more small layer of complexity to your
program, but some complexity would have to be introduced in any situation. The other disadvantage with this is that it
is not always an intuitive way to implement your program and requires some
amount of LabVIEW knowledge before one would generally come across this
technique.
In any case, I appreciate the time and effort you put in to
your suggestion. Please make sure that
you submit the suggestion formally through the NI Product Suggestion Center so
that it can be reviewed by some of the decision makers here.
Thanks again,

Let’s forget about VB part, even in Java script how do we create the Illustrator instance without bring Illustrator IDE up when you create the application object. It’s a COM component right, why would it bring up the UI? Do you have any simple example in Javascript please?
To the best of my knowledge in order to access the Illustrator object model that the application must be running through JavaScript since scripts are run via the UI.
I did find this in the documentation in refference to VB.
CreateObject launches Illustrator as an invisible application if it is not already running. If Illustrator is
launched as an invisible application you must manually activate the application to make it visible:
Set appRef = CreateObject("Illustrator.Application")
So instead of "As New" try "CreateObject"...
Just a guess really

Error could not access a java object field called allowAppDataInServContext after Applying Security

After applying the security patch 12-26 I am getting the error "Could not access a java object field called allowAppDataInServContext". When I removed the update the error goes away. When I read the update it returns.
The error states it occurred in the following line: cfapplication name="somename" clientmanagement="No" sessionmanagement="Yes" setclientcookies="Yes"

Is it a linux server? Look at the following, second comment.

Problem with Web Dynpro ABAP Adobe form Access via 'NULL' object reference

Hi All!
I'm a beginner of Adobe form.
problem 1:
I tried to display data in Adobe interactive form according to the tutorial :https://www.sdn.sap.com/irj/scn/weblogs?blog=/pub/wlg/7783. [original link is broken] [original link is broken] [original link is broken]
I checked every step, but unfortunately it reported an error: Access via 'NULL' object reference not possible. I found that the error happens when trying to get element of the context node.
I also have such problem when I was studying the tutorial https://wiki.sdn.sap.com/wiki/display/WDABAP/CallAdobeFormthroughABAPWebDynpro.
problem 2:
I can't input any data in input box or click any button even if I selected the property 'enabled' of the interactive form while my colleague can do it on his computer. Does it means that there are some thing wrong with my adobe reader?
Hope anyone could save me,
Thanks & Regards,
Murloc

Check that you have entries in the Table MARI. else you will get this message.

Nwdi-managed access of pcd-objects from java web dynpro

Hi,
im am trying to access portal pcd-objects from a java web dynpro component (namely getting and setting personalized iview properties). for locally managed web dynpro components this works fine with the code below.
when i try the same with a nwdi managed web dynpro component i run into problems regarding references to used dcs. for instance, i need to reference used dc SAP_JTECHS/tc/epbc/pcm/adminapi/java because the build needs tcepbcpcmadminapijava.jar which is inside the mentioned dc. but access permissions of this dc don't allow the dependency. when i try to "add used dc ..." in nwds i get the error message: illegal dependency: access list does not allow use of ...
has someone any solution for this problem? are there other ways of accessing pcd-objects from java web dynpro (nwdi managed!)?
thanks
heiko

     try {
          IAttributeSet attributeSet = (IAttributeSet) getIview(IVIEW);
          attributeSet.putAttribute(ATTRIBUTE, value);
          attributeSet.save();
     } catch (Exception e) {
private static Object getIview(String pcdPath) throws Exception {
     Hashtable env = new Hashtable();
     env.put(

          com.sap.portal.pcm.admin.PcmConstants.ASPECT_SEMANTICS);
     env.put(
          Context.SECURITY_PRINCIPAL,
          WDClientUser.getCurrentUser().getSAPUser());
     env.put(
          IPcdContext.PCD_PERSONALIZATION_PRINCIPAL,
          WDClientUser.getCurrentUser().getSAPUser());
     InitialContext iCtx = new InitialContext(env);
     return iCtx.lookup(pcdPath);

Hi Kust,
To access the PCD objects the code you used looks ok for me but your main issues is related to the dc access permissions. This thread discussed about the similar issue. Please review this below thread.
