Geoserver Mapfish Printing error while reading configuration file config.yaml

Question

I have installed Geoserver 2.8 in my server and mapfish Print plugin 2.8. I have deployed Geoserver Tomcat 8.0. I followed all steps mentioned in http://docs.geoserver.org/latest/en/user/extensions/printing/

When I restarted tomcat server 'printing' folder with config.yaml file created under Geoserver/ data folder. When I tried to verify installation by giving url : http://localhost:8081/geoserver/pdf/info.json

I get the below error :

    javax.servlet.ServletException: Error occurred while reading configuration file 'D:\Program Files (x86)\Apache Software Foundation\Tomcat 8.0\webapps\geoserver\data\printing\config.yaml': org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mapPrinter': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.mapfish.print.config.ConfigFactory org.mapfish.print.MapPrinter.configFactory; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'configFactory': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.mapfish.print.ThreadResources org.mapfish.print.config.ConfigFactory.threadResources; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'threadResources': Invocation of init method failed; nested exception is java.lang.OutOfMemoryError: unable to create new native thread

It says error reading config.yaml file. Can't find what is the error with Config.yaml.

Answer 1

I solved it. The problem was with the Printing-plugin version. I tried with another version and it worked.

Answer 2

Since this is still an issue with current docker images for geoserver, this is how i solved the problem:

Download the common-httpclient-3.1.jar

Copy it into the docker container and paste it into the /WEB-INF/lib folder (e.g /usr/local/tomcat/webapps/geoserver/WEB-INF/lib). Then restart Geoserver.
