Call in process VM from new Thread

Hi!
I have a c++-Project that creates a jvm in the main-Thread. Then a new thread is created. In the new thread I'm calling a Java-function ( packageFoo.ClassFoo.fooFunction() in foo.jar).
The function (fooFunction) is executed correctly until a point where an other class of an other package (in an other jar-file) (packageBar.ClassBar in bar.jar) is to be created. Here a ClassNotFoundException is thrown ("ClassNotFoundException: packageBar/ClassBar").
The ClassNotFoundException is not thrown if I call fooFunction out of the thread where the JVM is created.
The new Thread is registered with AttachCurrentThread and System.getProperty("java.class.path"), called directly before the exception is thrown, seems to be ok.

hi once again.
after some hours of searching:
The problem does't depend on classpath etc. but on jndi:
I can instance packageBar.classBar without problems directly. But classFoo.fooFunction uses JNDI.
I also found a bug-report:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4307751
and a discussion whit a similar problem
http://forum.java.sun.com/thread.jspa?forumID=40&threadID=432365
where it is said that the context classloader should be reset to solve the problem.
Well, I dont know to what to reset the classloader. I tried to save the classloader from thread A and set it in thread B but it didnt work so surely I did something wrong. Can somebody help me?

How to call a sequence in a new thread from C++ dll

Here is what I am trying to do:
I implemented a dll that monitors network traffic, and it also supports message handlers that can be triggered when a specific message has been received. Essentially the receipt of a message is like an event causing additional code to be executed. What I need to do is have the message handler in the dll call/execute a sequence (either is the same sequence file that originally called the dll, or in a different sequence file). Also I want the sequence to be executed within the same execution object for the purpose of result collection and report generation. I am expecting the dll to have to launch a new thread to call a sequence because of the asynchronous nature of the message received event.
There are easier ways to achieve the same result, but one of my goals is to make it easy for a test developer to configure a message handler, by having only one step in their sequence to configure the message handler. I want the rest to be transparent to the user.
I am unsure about how to implement this feature, so I am asking for any examples, ideas, comments before I start trying things out.

Assuming that I understand your question correctly, it would seem to be the best way to do this would be to pass the Execution object to the DLL (either through a direct pass of the Execution object or passing the sequence context, from which you can get the Execution). Then simply call Execution.NewThread, specifying the SequenceFile object (accessible from Engine.GetSequenceFileEx) and then passing the Thread object out as an output. Your sequence file in which your DLL is called could then simply have a Wait step which is configured to wait on that Thread object. What happens in this case is that the results are collected for that thread (which is being executed asynchronously) and returned as the results for the Wait step.
Although you are probably not using LabVIEW, I have attached an example of this in LabVIEW that might be helpful just for seeing the flow.
Thanks,

Why can't I make call to parse HTML from inside Thread?

This is driving me crazy. With a defined HTMLEditorKit.ParserCallback object "callback", I am attempting to parse an HTML document retrieved from a URL by using:
new ParserDelegator().parse(new InputStreamReader(url.openStream( )), callback, true);
It doesn't work if I initiate the call in any way from within the run method of a Thread subclass (the way I'd like to do it). If I make the call in the constructor of the Thread subclass, however, it runs fine. I know it must have something to do with the fact that parse runs in a Thread of it's own - but the way to fix it isn't apparent to me.
I would appreciate some words from people who might know what's happening here... THANKS in advance.

Don't bother - figured it out - thanks.

Aperture processing images from new Canon 5D mark II

Hi, I'm wondering if anyone has attempted to process images from the new 5D mark II with aperture. It's my understanding that aperture cannot process the images as of yet.
Also, does anyone know if there is or if there will be a plug in available for aperture to process the images?
Thanks,
Trish

Calling a sequence in a new thread with different values

I have a sequence that I want to call that runs in parallel (seperate thread). The question I have is that I want to run this sequence from a lot of different places, but with different values of the variables going into the steps inside the sequence.
If I change the values inside the sequence (running on seperate thread), then I will have to duplicate this sequence over and over. What I really want to be able to do is run a step in a seperate thread, and not wait for it to complete. Is this possible? Or a method of passing step values into a seperate thread. I don't want to use globals unless I really have to.

Hi ADL,
I have attached an example which I hope will illustrate an answer to your question.

Problem when calling BPEL process (WS) from APEX

I am trying to add a web service call to a BPEL process I have created (tried a few others aswell), but every time I try to add the WDSL file I get the following error:
*1 error has occurred*
The WSDL document contains multiple SOAP bindings. Application Express only supports WSDL's with one SOAP binding. Click Create Web Service Reference Manually to continue creating a reference for this service.
It is a simple BPEL process which works fine when called from the BPEL Console, however I have no success when calling it from APEX.
Am I doing something wrong, or is there a bug in BPEL/APEX?

Allow me to reply to my own thread, for the benefit of any others who might want to invoke a BPEL WS from APEX facing the same problem:
Apex does not seem to like asynchronous BPEL processes so the trick is to make a synchronous BPEL process call the asynchronous BPEL process.

Calling BW Process chain from Visual Composer

Hi Gurus,
i have a question. Does anyone testet to call an ABAP program or a process chain in BW (via ABAP) through a button in visual composer?
Regards,
Adem

Hi Adem,
this is possible, you must write an RFC function module,
which calls a function module of the function group
RSSM_PROCESS.
For example you want to start a attribute change run you have to call the function module RSSM_PROCESS_ATTRIBCHANGE
from your RFC function module.
Best Regards,
Marcel

How to call OWB Process Flow from APEX?

Hello.
I was wondering if there is a way that I can have a OWB process flow kick off from a button in APEX? I know you can have APEX perform PL/SQL upon being clicked, so I am wondering if there is a way that I can do the same for a process flow? We are looking to have a manual kick off for a job and we are trying to use APEX for this. Any information would be great!
Thank you

Hi Ashna,
You have use three different forms for three buttons. But I think all are commented one.It will also work if you uncomment it.
Else you can use only one Form without giving action in form tag. Use normal buttons instead of submit type buttons & call different JavaScript functions on onClick event for each button.
Try this out.

Any ideas?
Thanks fort your help so far

WCF called from Sharepoint - thread abort exception

Any idea what can be wrong?
Many thanks

Hi,
thanks for your reply. Now it seems that everything works (I'm still keepng my fingers crossed ;-)
What we did:
1) to the page I added
protected void Page_Load(object sender, EventArgs e)
this.Page.Server.ScriptTimeout = 3600;
2) to WCF confing at server side we added
<serviceThrottling maxConcurrentCalls="100" maxConcurrentSessions="100"/>
But if this is what helped, I don't know. The timeout had to be already set in cofig files, but this is only what the SP server administrator claimed, I haven't done it personally. This seems to be much clear
for me.

How can I include the results are coming from a new thread, in the main sequence report?

Hi,
I have a main sequence which calls other sequence running in a new thread.
I cannot see the results (limit test etc.) comming from that sequence.
Is there any trick to it?
Andras

Hi again Andras.
I got a reply from the technical support. I hope this help you.
To include in main report the results of your test in another thread you must follow these steps:
1.- Right click on the sequence call where you create the new thread. In "Specify Module" panel, just right "Run sequence in a new thread" press "Settings" button and disable "Automatically wait for the thread to complete..."
2.- At the end of your main sequence add a new "synchronization - wait" step. Configure your wait, selecting in the upper ring tab "wait for thread".
3.- Then select below "specify by sequence call" and pick over your thread name.
With these changes your main sequence will add the results from your thread to your main sequence report.
I hope it works for you. (but sadly it doesn't work for me)

Calling sequence in a new thread multiple times gives debug warning "reference not released properly"

Hi,
I am including steps inside a sequence which calls sub sequences in a new thread. After calling each sub sequence in a new thread, I am putting Wait step which is configured to wait for the respective sub seueqnce to complete its execution. When I include these steps (call a subsequence in a new thread and then configuring wait to complete it) once, it executes properly but when I includes these steps twice, I get debug warning when I close Teststand sequence editor. Due to this behaviour, when I run this sequence through operator interface (Simple OI), I get run time error R6025.
I checked if there is any object reference which might not be released, but could not figure it out here. Please see attached sequence and the debug warning message.
Used version: Teststand 4.0.1, LabVIEW 8.5, Windows XP
Kindly help.
Thanks in advance,
Nirmal

Hi Nirmal,
Thanks for the detailed instructions. I tried exactly what you said and I still do not see the leak. The problem is likely specific to something customized on that machine or in the very least does not happen every time or on all machines. I'd recommend trying to narrow down by eliminating the possibility of an unintended customization. If you can try installing a clean install of teststand on a clean machine and see if you can still reproduce the problem then that would help narrow things down a little. If you can't reproduce it on a clean install on a clean machine then I'd start looking at what's different on the machine you can reproduce it on. You could remove your config files to eliminate customizations to settings such as search directories. You could remove files from your components\User directory to eliminate the possibility of using those. Just a few ideas. Other people might have some other ones.

JNI calls only work if sent from main thread?!?

Hi,
I searched through the forum for a couple of hours now, and found that a lot of developers seem to have problems with JNI and threads. However, I couldn't find a solution to my problem so far...hope you can help!
We need to send requests to a DDE Server from our Java application. For that reason, we implemented a very small DLL using Delphi, which calls the DDE Server and returns the result as a string. Using JNI, we call this DLL from Java.
Everything works fine, as long as we call the DDE Server (via JNI and the DLL) from the main thread of the Java application. But everytime we call it from another Java thread, our DDL reports that it can't get a connection to the DDE Server. This is especially awkward if you want to make calls as a reaction to GUI events, since then the call is sent by the Event Dispatch Thread of the Java runtime.
This does not seem to be a multi-threading problem, since we do never send multiple requests at the same time. It simply depends on the thread, from which the call is sent.
Any hints are appreciated very much.
Thanks!

We are a step further now...thus the problem to be solved changed a little bit.
The former assumption, that connecting to the DDE server does only work from the main thread was false. It only seemed like that, because we called System.loadLibrary() to in the main thread to load the DLL . In fact, the connection to the DDE server works from any thread - you just have to make sure that System.loadLibrary() is invoked in this same thread.
This means: if System.loadLibrary() is invoked in the Event Dispatch Thread, we can call the DDE Server from this thread, which is what we primarily wanted to do. So our problem is solved.
Anyway, I made some more tests to find out, what happens if I start multiple threads, with each of them calling System.loadLibrary(). The result was, that only the first thread is successful. This means: the first thread, which loads the DLL is the only thread that is able to connect to the DDE server. All other threads won't get a connection.
What could be the reason for that?
