Hi,
ENGINE loads a xml descriptor. In simple Ruta projects they are located
in descriptor/utils which would result in 'ENGINE utils.HtmlAnnotator;'.
Loading the xml descriptor from the dependency or even the installed
OSGi bundle should also work. I would have to check what the exact
problem is in the project configuration.
However, if you want to load an analysis engine from the maven
dependencies, it is simpler to initialize it directly with uimaFIT
instead of the xml descriptor. This would result in something like
'UIMAFIT org.apache.uima.ruta.engine.HtmlAnnotator;'.
It should not look relative to the current package, but I have to check
that.
Best,
Peter

Hi Peter!
Bonus question: how do I get Engines and Type Systems included through
maven dependencies to resolve correctly in scripts?
For instance:
PACKAGE de.miba;
ENGINE org.apache.uima.ruta.engine.HtmlAnnotator;
ENGINE org.apache.uima.ruta.engine.HtmlConverter;
TYPESYSTEM utils.HtmlTypeSystem;
TYPESYSTEM utils.SourceDocumentInformation;
Document{-> RETAINTYPE(SPACE,BREAK)};
Document{-> EXEC(HtmlAnnotator)};
Document { -> CONFIGURE(HtmlConverter, "inputView" = "_InitialView",
"outputView" = "plain"),
EXEC(HtmlConverter)};
All the ruta dependencies are on the class path, but the script can't
find it ("error: "org.apache.uima.ruta.engine.HtmlAnnotator" not
found.). I assume it's looking relative to current package (de.miba.*)?
Regards,
Michael

Hi,
I had a quick look at your ruta-test project.
1. There was problem for the paths config of your annotator
description. If you use a java/maven project, it is easier to just
use the classpath instead of the Ruta paths. So I removed
'descriptor:descriptor' from the pom and moved the descriptor folder
to src/main/resources.
2. I added 'TYPESYSTEM descriptor.typeSystemDescriptor;' to your
TestProjectMain.ruta (after the UIMAFIT import) and deleted the JCas
cover class in 'src/main/java' as it is now generated and located at
'target/...'
3. I added a '.addToIndexes()' in TestAnno so that the annotation is
available and added 'EXEC(TestAnno);' in TestProjectMain.ruta so that
the annotator is executed. The keyword UIMAFIT is just an import of
the analysis engine.
4. I added 'Assert.assertEquals(1, JCasUtil.select(jcas,
SomeType.class).size());' to RutaTest.java in order to check if the
annotation is created.
If you want, I can open a pull request with the changes for your
project or for a fork.
Best

Hi everyone!
I'm at a loss here. Trying to create a basic RUTA project, but I
just can't get it to work. I'd like to include a custom Engine (Java
code!) that needs a few maven dependencies. I just can't get RUTA
(via ENGINE/TYPESYSTEM) to properly include and initialize Java
annotators.
What I tried so far:
- Create project using archetype
- Add code for custom AE
- Add TS and AE descriptors in ./descriptor folder, run JCASGen
- Add <buildPath>descriptor:descriptor</buildPath> to pom (in the
ruta-maven-plugin section). ./descriptor folder is configured
successfully as part of build path
Issues:
- When using ENGINE aeDescriptor in script, project doesn't run:
Caused by: java.io.FileNotFoundException: class path resource
[aeDescriptor.xml] cannot be resolved to URL because it does not exist
- TYPESYSTEM typeSystemDescriptor <- works in editor, but maven pom
/ task throws an error (no details, assuming name/path can't be
resolved)
- UIMAFIT de.miba.TestAnno works (and can be executed in ruta
script), but Types/TS missing, so runtime errors.
Any hints or an example project where this works would be highly
appreciated! I've uploaded the skeleton to
https://github.com/mybyte/ruta-test
Cheers,
Michael
