Java External Interface

How can Java be used to communicate (interface) with external perperihals (just like C++)?
eg. sending signals thru com ports.

There are APIs on the java site for serial communication (COM1, COM2 ... ) and for USB communication. Check them out.

1) Your JavaScript function name and the function name you
are calling
don't match.
2) On the Flex side, you are calling a JS function that I
think you are
expecting to return a value, but not assigning the result of
the value to a
function.

Memory leak in external interface SetReturnValue?

I'm having trouble with a memory leak in my application. I'm
hoping someone out there can help me find a fix or workaround, or
tell me what I'm doing wrong.
The leak seems to be coming from the flash external
interface; specifically, IShockwaveFlash.SetReturnValue(String). My
application is written in Visual Basic 2008, connecting to Flash
9.0.124.0 (activex version).
I've written a fairly simple flash/VB program pair to
illustrate the problem.
The SWF contains a button, 2 dynamic text fields, and the
ActionScript 2 code below.
The VB project contains a Form with a AxShockwaveFlash object
and the VB code below.
When this program is run, and the button is clicked a lot
(10's of thousands of times), the application's memory creeps up
and never seems to fall back down. If the string passed to
SetReturnValue is longer, memory is consumed faster. But if the
call to SetReturnValue is commented-out, the application's memory
usage remains stable.
If anyone has any suggestions on how to proceed, I'd be
grateful.
(By the way: I'm using a freeware program called DoItAgain to
automate the button pressing.)

I have developed two simple Java and corresponding
C++ classes. Use code tags when you post your code.
You are missing a lot of error checking. JNI calls, every single one, will usually be followed by some sort of error checking. Any that access classes, methods, fields or allocate object must be followed by checks for java exceptions.
You will need to reduce your code to a smaller sample. Otherwise it is unlikely anyone will look at it.
You also need to specify how you know that a memory leak is occurring.

Delete Intransit from APO which Loaded by PI from external interface

Hi all,
I am facinf a problem in deleting the Order created by External Interface.
We are loading Inransit as PO Mamo (ATP Category AH). Now we need to delete all the Record with AH ATP categoy before we reload new intransit to APO.
Problem is we are not able to delete those order as those are not in Live Cache.
We try using transaction /n/sapapo/bp2 but every time its throwing error "SAP APO system Q51CLNT100 has been declared as an SAP R/3 system.
and even i try deleting from /SAPAPO/RLCDEL. but its not deleting those order.
Can some one suggest what to do.
What all the option that we can try to delete the intransit.
Thanks & Regards,
Amit Sharma

Hi Amit,
You can use BAPI to delete AH ATP Category.
1. Read all Purchase Documents from BAPI_POSRVAPS_GETLIST3 for product u2013 location for AH Type ATP Category only.
2.Get the ORDID on the selection made.
3.Call BAPI_POSRVAPS_REMOVEITEMS and load the list of order no. and then delete it.
Please try this.
Thanks,
Dipankar

ASA 5505 external interface dying

Hi,
We have an ASA 5505 ( version 9.1(2) ) that frequently stopped functioning ie the external interface refuses to pass any traffic , ASDM wont connect,etc.
The internal interface does continue to function and if we SSH into the unit and do a reload , everything springs back into life again.
What are the best steps to troubleshooting and finding a fix to this problem?
Chris

Hi Amrin,
you can configure SLA monitoring on ASA and that woudl work fine for you:

Hope that helps.

ASA 5510 Anyconnect VPN question-"Hairpin" vpn connection on same external interface

I have a Cisco ASA 5510, I want to allow a VPN connection to be established by a client on one of the inside interfaces(10.20.x.x) to be able to go out the single External interface and get authenticated by the ASA to create a VPN tunnel to the other inside interface (10.0.X.X) and access resources on that subnet.
Basically want clients on a WLAN to be able to VPN back in to the LAN with the ASA in the middle to get to company resources,
Is this possible?
Thanks,
Tommy

When we connect any VPN on a device then it is always a TO THE DEVICE connection and I am afraid we can connect only to the local / nearest interface where user is connected in a network with respect to ASA.
I have seen this scenario working though earlier with one of my clients wherein he has configured his DNS server accordingly so that depending upon the source of the DNS request an appropriate IP address was provided for same DNS name. For example if user from IP address range 192.168.0.0 range connects to abc.com then it will get IP address 192.168.1.1 and if a user from range IP address10.0.0.0 connects then it will get 10.1.1.1.
If we configure the same scenario as well then your requirement will be fulfiled with same name however VPN has to be enabled on wireless interface again. If not, then as you have described configuring a new domain name for VPN connection only for wireless users should do the deal.

Anuj

Is there a way to run an existing PS-JS script using external interface

I have several previously written Photoshop JS scripts which I'd like to run through buttons on PS panels, much like the example for the HelloWorld introduction. I assume that--using external interface--I'll somehow be able to fire off these script files. Is this a correct assumption?
Thanks!

Certainly, but not with external interface.
Have a look at the cookbooks. There are examples of how to use the root host object to call directly into extendscript.

Two external interfaces; one to be used for outboud; second to be used for incoming VPN\Web traffic.

I'm configuring our ASA and we have two AT&T circuits which we're only using one with our current Juniper firewall. I know the ASA doesn't support policy based routing so I'm wondering if the following hypothetical "config" is possible.
External Interfaces:
OUT_01 - 12.133.X.X
OUT_02 - 201.61.X.X
I would route all internal traffic to go out through OUT_01.
We have over 5 site-to-site VPN and 30 external facing servers. Could I use OUT_2 to configure all the inbound connections for the VPN and NAT rules?

You can configure the ASA to allow asynchronous routing, as you are describing, by configuring TCP bypass.
http://www.cisco.com/c/en/us/td/docs/security/asa/asa82/configuration/guide/config/conns_tcpstatebypass.html
What this will do is you will still need to send traffic out one interface but the ASA will accept return traffic on either of the outside interfaces. Configuring this can be a security risk as the ASA will ignor the state table.
Or you could wait until ASA version 9.4 which will have support for PBR. Ofcourse this is the first version that will support it, so don't be suprised if it has a few bugs.

What does "No External Interface" mean?

Adobe Flash Player will not install the complete program. It's telling me that it can only install a single file at a time. The display box states that I have version 9.0.45.0 installed and my operating system is Windows XP then for the browser in states No External Interface. Not sure how to correct the problem but it's telling me that Flash Player didn't install completely.

Download and run the offline installers from http://helpx.adobe.com/flash-player/kb/installation-problems-flash-player-windows.html#mai n-pars_header (under the heading Progress bar hangs).

External interface memory leak?

Hello,
I am embedding the flash player inside a Visual C++
application. My program uses the external interface extensively.
The external interface is called several times a second ( ~20 fps )
each time a ~1k XML string is passed to the flash player.
During execution the program increases its memory by ~10 Mega
each hour. I have used the Umdh tool to try to locate the problem.
It points to the line where the container program uses the external
interface to call a function inside the swf movie.
Below is a typical output of the Umdh tool:
+ 3396588 ( 3405883 - 9295) 261991 allocs BackTrace12EF

The System.totalMemory value of the flash player ranges from
2.2 Mbyte to 3.2. I tried using memory leak detection software like
IBM's Purify but couldn't find the problem.
I also tried to disable the BSTR caching by setting the
environment variable OANOCACHE, but the memory of my program
continues to increase.
Below is my C++ code. The m_iflash object is a pointer to the
ActiveX of the flash player.
wstring CZFlash::CallFunction(wstring call_string)
BSTR pcall_string = SysAllocString(call_string.c_str());
BSTR presponse = NULL;
HRESULT status = m_iflash->CallFunction(pcall_string,
&presponse);
SysFreeString(pcall_string);
if (status != S_OK)
if (presponse != NULL)
SysFreeString(presponse);
return L"";
wstring sresponse(presponse);
SysFreeString(presponse);
return sresponse;
Currently the swf movie contains only action script that
displays the System.totalMemory value and an empty function that
the external interface calls.
Any help will be appreciated.
Thanks in advance,
Amit

Hello,
Thanks for coming to National Instruments Discussion Forum.
Can you give us more details about your application? Basically, I can’t find your main VI for your User Interface. Can you also give us the different steps to do to run your application and reproduce your problem?
Generally speaking, your code on your block diagram have to be displayable in one screen.

Hide messages for External Interface Program Error

Hi,
I am facing problem in removing the external interface errors encountered during EPC of a Y program. Can you please suggest any solution for hiding the error in the custom Y program using #EC.
Regards,

Hello IvoK,
The 9881 needs to be externally powered. You can do it with a CAN Breakout Box or with a CAN cable.

Java Application interface with MS Excel through DDE

We have a financial application written in JAVA and have requests from users that want to interface with the application. Meaning, They would like the Java application interface with Excel. For example, if you had a C++ application, you could create a DDE link in Excel that points to the C++ application and receive the data.
How could I do this with a Java Applictaion ? I was told that there was an application written that lets Java interface with Excel.
Any ideas or does anyone know ?

Creating PO in SRM through external interface

Is there a way to create a PO in SRM through an external interface without creating a shopping cart? I see that we can create a shopping cart through BBP_PD_SC_CREATE_EXTERNAL. But we need to create a PO in the SRM system without the shopping cart. Is this possible? It's neither the classic nor extended classic nor the standalone SRM scenarios that all have the shopping cart generate the PO. Is there a way to create the PO without the shopping cart? Is there a BAPI to do this?
Right now, we generate an XI ABAP server proxy which allows us to push the PO information from an external system through XI into SRM, but we do not know what SRM function we need to invoke.
Any help would be appreciated.
Thanks,

SAP Integration Consultant

I can give you the technical example of how to create a PO. You can get the sample logic of creating PO's from the program MBT_PO_MASS_CREATE.
