Structs in Method call

[Avada]

Hi,

i am new to j-interop and have a problem with structs.

i am trying to call a method in a DCOM object which has 5 parameters, all of them are of type Struct.
I tried the following to call that method:

IJIDispatch dispatch = (IJIDispatch)JIObjectFactory.narrowObject((IJIComObject)excelObject.queryInterface(IJIDispatch.IID));
         
JIStruct param1 = new JIStruct();
JIStruct param2 = new JIStruct();
JIStruct param3 = new JIStruct();
JIStruct param4 = new JIStruct();
JIStruct param5 = new JIStruct();
param1.addMember(new JIString("test"));
param2.addMember(new JIString("test"));
param3.addMember(new JIString("test"));
param4.addMember(new JIString("test"));
param5.addMember(new JIString("test"));
       
dispatch.callMethodA("StartService", new Object[] {param1, param2, param3, param4, param5});

As result i get the following Exception:
org.jinterop.dcom.common.JIRuntimeException: Unsupported type for VARIANT.  [0x00001030]

Is it not possible to call methods with parameters of type struct, or am i using the JIStruct class in a wrong way?

Any help would be appreciated.

Thanks,
Stefan

Hi ,
     Can I see the IDL signature for this method. (Complete one please).

Thanks,
best regards,

Hi Vikram,

thanks for your fast answer.

The IDL for the COM object is the following:
