[solved] Assign repository in JAVA

radone

How can I assign repository location to JAVA application?

Where is my problem:
I would like to run external "execute_process" process from my current process.

Notification:

INFO: Cannot access file system in execution mode UNKNOWN. Not loading repositories.

JAVA Code

                RapidMiner.init();
		try {
			RepositoryManager.getInstance(null).addRepository(new LocalRepository("MyRepo", new File("processes")));
		} catch (RepositoryException e1) {
			e1.printStackTrace();
		}
		Process process = null;
		try {
			process = RapidMiner.readProcessFile(new File(annotationProcess));
			// RepositoryProcessLocation loc = new RepositoryProcessLocation(new RepositoryLocation(annotationProcess));
                        // process = loc.load(null);
                        
                        IOContainer results = process.run();

		} catch (Exception e) {
			e.printStackTrace();
			RapidMiner.quit(RapidMiner.ExitMode.ERROR);
		}

"execute_process" operator definition:

<operator activated="true" class="execute_process" compatibility="5.3.000" expanded="true" height="76" name="Execute ExtracGlobaltFeatures (3)" width="90" x="246" y="120">
        <parameter key="process_location" value="RMModule/processes/ExtracGlobaltFeatures"/>
        <parameter key="use_input" value="true"/>
        <parameter key="store_output" value="false"/>
        <parameter key="propagate_metadata_recursively" value="true"/>
        <parameter key="cache_process" value="true"/>
        <list key="macros"/>
      </operator>

Error:

com.rapidminer.operator.UserError: Cannot resolve relative repository location 'ExtracGlobaltFeatures'. Process is not associated with a repository.

Thanks for any help.

The solution was to add: (the processes are in "processes" directory):

                try {
			RepositoryManager.getInstance(null).addRepository(
					new LocalRepository("MyRepo", new File("processes")));
		} catch (RepositoryException e1) {
			e1.printStackTrace();
		}

and to change to //MyRepo/ExtractFeatures:

<operator activated="true" class="execute_process" compatibility="5.3.000" expanded="true" height="76" name="Execute ExtracGlobaltFeatures (3)" width="90" x="246" y="120">
        <parameter key="process_location" value="//MyRepo/ExtracGlobaltFeatures"/>
        <parameter key="use_input" value="true"/>
        <parameter key="store_output" value="false"/>
        <parameter key="propagate_metadata_recursively" value="true"/>
        <parameter key="cache_process" value="true"/>
        <list key="macros"/>
      </operator>
