All data is accessible via a REST API. +The REST API does **not** follow the HATEOAS approach. +The URLs follow the pattern `///`, where `type` is `servicetemplate`, `nodetype`, ... +Below a concrete instanance, subresources such as `name` exist. + +Definitions are not modeled as explicit element. Only the nested elements are handled by Winery. +That means, it is not possible to specify custom definitions bundling a customized subset of available elements. + +Intentionally, a QName should be unique within the repository. +We did not follow this assumption, but only require that QNames are unique within a type. +That means, the repository allows `{http://www.example.org}id` for both a service template and a node type. +We introduced TOSCAcomponentId uniquely identifying a TOSCA element. +Future versions might redesign the backend to use a QName as the unique key. + +Currently, Winery is switching from plain Javascript library loading to [RequireJS]. + +The file `src/main/webapp/WEB-INF/common-functions.tld` and the files in `src/main/webapp/WEB-INF/tags/common` are copied from the sister project `org.eclipse.winery.topologymodler` at `mvn generate-sources`. + +### Trouble shooting +In case, `Version.java` is not found, then run `mvn compile`, which should trigger a regeneration of Version.java. + +The error message +`HTTP Status 500 - com.sun.jersey.api.container.ContainerException: org.apache.jasper.JasperException: The absolute uri: http://www.eclipse.org/winery/functions cannot be resolved in either web.xml or the jar files deployed with this application` indicates that `mvn generate-sources` was not run. + +In case `javax.servlet.jsp.PageContext` cannot be found: +Project -> right click -> Properties -> Project Facets -> Dynamic Web Module -> "Runtimes" -> "New..." + +When running in jetty 9.0.5, there is always the error message "Request Entity Too Large" when uploading a file. +There is the `maxFormContentSize` set in `jetty-web.xml`, but it currently does not help to solve this issue. + +When doing a copy-libs-to-tomcat hack, possibly "W3C_XML_SCHEMA_NS_URI cannot be resolved or is not a field" appears. +Remove `stax-api-1.0.1.jar` out of `tomcat7/lib`: Java's `rt.jar` should be used instead for `javax.xml.XMLConstants`. + +## License +Copyright (c) 2012-2014 University of Stuttgart. + +All rights reserved.
