Repository Location For API
There is probably an obvious solution to this, but I am at a loss. I am trying to read data from a repository into an operator. Everything works well in the GUI. I am trying to build an application using the RapidMiner API. I have taken the generated XML and used it in the constructor for the process class. When I call the run method an exception is thrown. This is the error message:
"Cannot retrieve repository data from entry '//NewLocalRepository/newdata/TrainingData'. Reason: Entry '//NewLocalRepository/newdata/TrainingData' does not exist "
This is the operator XML
<operator activated="true" class="retrieve" expanded="true" height="60" name="Retrieve" width="90" x="45" y="75">
<parameter key="repository_entry" value="//NewLocalRepository/newdata/TrainingData"/>
</operator>
I have tried the absolute path of the repository and i get the error message:
Cannot resolve relative repository location '/Users/Brett/Documents/RapidMiner/newdata/TrainingData'. Process is not associated with a repository.
I am using RapidMiner 5.0 under Windows Vista

I solved it. I needed to create a LocalRepository and add it to the Respository manager. Of course this is done automatically in the RapidMiner GUI.
I met the same problem, and I tried what you said, but it failed,why? Here are the code:

//------------------------------------------------------
File localRe = new File("E:\\cup\\proc\\ProgramXML");
LocalRepository local = new LocalRepository("local",localRe);
RepositoryManager.getInstance(null).addRepository(local);
I am running into this problem as well. What is the procedure for creating a local repository without using a GUI?

Hi,
as always it would help to know how it fails...So any exception? Or is just a null returned? What does the log say?
