+
+Java library for WikiPathways webservice
+
+Currently under development and testing.
+
+With this library you can access the pathway database WikiPathways from Java through the REST webservice API (http://webservice.wikipathways.org).
+The old SOAP webservice will be discontinued in the near future (spring 2015) and all functionality (also updating and uploading information) have been implemented in the REST API. 
+
+Be aware that update and upload functionality provide special permissions that need to be requested before using those webservice functions. 
+
+Compile the code and run the tests with:
+
+```
+cd org.wikipathways.client
+mvn clean install
+```
+
+If you want to use a different web service, use (for example):
+
+```
+cd org.wikipathways.client
+mvn -Dwp.webserver=http://otherservice.wikipathways.org clean test
+```
+
+## OSGi bundle
+
+Create the OSGi bundle with:
+
+```
+cd org.wikipathways.client
+mvn bundle:bundle
+```
