问题
Till now, I had been running ruta scripts from a maven project by creating AnalysisEngine and CAS, and processing the engine. To do this, I had placed all the scripts and descriptor files (Engine & TypeSystem) into scr/main/resources folder of the maven project.
Now I want to place the scripts and TypeSystem files in an external path and pass the path dynamically to my java code that runs the scripts. Is it possible to do it ? If so, how ?
I simply placed the files(script & descriptor) in an external path and passed the new path to instantiate the AnalysisEngine as below;
final AnalysisEngine engine = AnalysisEngineFactory.createEngine("home/admin/Desktop/TEST_ScriptFolder/com/textjuicer/ruta/date/Dazzle_ChapRef_UpdatedEngine");
Error
org.apache.uima.util.InvalidXMLException: An import could not be resolved. No file with name "home/admin/Desktop/TEST_ScriptFolder/com/textjuicer/ruta/date/Dazzle_ChapRef_UpdatedEngine.xml" was found in the class path or data path.

There are two layers:
- The RutaEngine needs to find the scripts/resources/descriptors
- UIMA needs to be able to resolve imports of descriptors
The resource lookup in Ruta has two stages, it searches for them in the absolute paths specified in the configuration parameters. If the resource is not found it searches for it in the classpath. So you need to set the configuration parameters: scripts are located in scriptPaths, descriptors are located in descriptorPaths and wordlists are located in resourcePaths. See the documentation for further information.
The problems with the imports in descriptors can be solved by either setting the datapath in the UIMA ResourceManager or by changing the import to "location" instead of "name". The datapath can be used as a replacement for the classpath. The Ruta descriptos use import by location if it specified int he ruta-maven-plugin.
