An abstract pathname is an object of java.io.file, which references a file on the disk. It returns the abstract file path as a string. The getPath() method belongs to the File class of Java. Get File Path Using getPath() Method in Java. NET mechanism for serialization, will cause the runtime to attempt to use Load() (not LoadFrom()) to get access to your workflow assembly, and thus will fail because it is not located in one of the paths probed by the standard Load mechanics (which yes, includes the application's directory and the GAC). The java.io.file class has three methods to find the path of a file. The second part of the operation, as it uses the standard. Now, the issue occurrs because of the way GetWorkflowDefinition() works: it essentially clones the activity instance, and Activity.Clone() works by serializing the original activity instance into memory and then deserializing it again into a new object graph. The problem here is that the runtime considers both LoadFrom() and Load() as different operations that operate in different contexts, and assemblies loaded in one context are not compatible (i.e are even considered different) from the ones loaded on the other context.Ĭheck Suzanne Cook's blog for the gory detaiils on binding contexts during assembly loading if you're interested in understanding this in detail. The issue is that you're loading your workflow assembly using Assembly.LoadFrom() and not Assembly.Load(). I think I can explain what your problem is. I am obliged to put the DLL in the current directory if I want to use GetWorkflowDefinition. Only WorkflowInstance.GetWorkflowDefinition needs the DLL to be in the current directory, while WorkflowInstance.Start doesn't. So the workflow type is already in the memory, isn't it? _wi = _wr.CreateWorkflow(workflow_type, variable_list)
