Something must have been corrupted in my environment. I created a brand new project, copied all the java source files into it, added JACOB as a library, and the error disappeared. Belay that - the errors are still present. Do I even need that ComThread.InitMTA() statement?

I'm trying to develop a utility to interface with an ASCOM device using JACOB.

Long time ago, but still the same problem! The problem is not the last parameter: 2. It's the missing PrintRange parameter. The parameter is optional, but check this: https://sourceforge.net/p/pywin32/bugs/339/ (It defines "[in, optional, defaultvalue(0)] PrintRange* PrintRange" which leads to the generation of "PrintRange=0") Same problem for jacob. I had the same problem and solved it like this: Dispatch printOptions = Dispatch.get(presentation, "PrintOptions").toDispatch(); Dispatch ranges = Dispatch.get(printOptions,...

Its also interesting that memory is consumed by JVM, but not by Heap. Heap is stable. JVM's consumption is not.
-
I wonder if source of my problem can be the design when I call some COM method via Dispatch in the same thread which delivers events from DispatchEvents to me?
-
Its interesting to add, that Runtime.getRuntime().freeMemory() is not showing the memory leak. That memory is more or less stable. While JVM memory consumption I see in Windows / Task Manager is growing quite fast.

Hello everyone, please help me with a typical issue. I have tried several suggested solutions, but they fail. Setup: JVM 1.8, Jacob 20, x64 I have a code which is using DispatchEvents class. Many events come to my side from server, which is ActiveXComponent. Events are represented as Variants. Events a delivered to Callback class by many threads. The problem is that Variants are never cleaned up. I tried to use -Dcom.jacob.autogc=true - no effect ComThread.InitSTA and ComThread.Release - JVM dies...

I know its several months after your question, but try taking a look a this answer. https://stackoverflow.com/questions/65125191/exception-access-violation-in-jacob-dll-using-vm-in-jenkins-pipeline It's says that maybe you should try to downgrade your java build to 141 and see if it works.

We use Jacob in the multi-threaded mode. In the case when the network connection is unstable (hence, data loss can occur), we have the following problem: During operation, the program execution occasionally hangs in the Java_com_jacob_com_EnumVariant_release(), line: ULONG refs = self-> Release(). This "hung" state is always preceded by the occurrence of a ThrowComFail in the Java_com_jacob_com_EnumVariant_Next() method. To emulate a bad network connection, we used https://jagt.github.io/clumsy/....

I found out the reason. The thread (from thread pool of application server) that created the instance was removed from the thread pool. It seems that a COM instance has the context of the thread and lives as long as the thread, that created it.

We are using JACOB in a web application (JSF, JPA, Wildfly Application Server, OpenJDK) to interact with another c/c++ application. Our problem is that after 1-2 minutes of inactivity the instance of the C++-COM-Dll is cleaned up and the destructor is called. This behaviour is reproducable not every time, but quite often. After the instance was cleaned up, a call of invokeev (Dispatch.cpp) ends up in an "Can't map name to dispid" error. The finalize() or safeRelease() method of the ActiveXComponent-instance...

jacob 1.18 (tried 1.20 too). A call of this method: [id(0x60020003)] HRESULT GetFacesAt( [in] BSTR point, [in] ICoordinateSystem coordinateSystem, [out, retval] SAFEARRAY(ISimObject)* pRetVal); should return an array of dispatches.

Hi, 1) I've been trying to read the documentation to figure out what JACOB actually does and I have no idea. What does JACOB do? 2) It seems like it automates java programs using activex as an interface. This can be used for testing and automation. When I went into the documentation it presented an activex component which takes a dispatch object or a program id. Where do I get the program ID from? I also dont really understand how the dispatch object works.

Presently this is not overridden at all from java.lang.Throwable. It would help debugging a lot if it could be overridden such that if the hResult attribute is non-zero it is displayed in hex, so that we can see immediately whether it is E_INVALIDARG etc. as per https://docs.microsoft.com/en-us/windows/win32/seccrypto/common-hresult-values.
