Spring integration Splunk: Failed to read schema document - spring-integration

Question

I am getting the below error while running Splunk integration spring adapter.
org.xml.sax.SAXParseException; lineNumber: 16; columnNumber: 212;
schema_reference.4: Failed to read schema document
'http://www.springframework.org/schema/integration/splunk/spring-integration-splunk.xsd',
because 1) could not find the document; 2) the document could not be
read; 3) the root element of the document is not .
I tried to search http://www.springframework.org/schema/integration/splunk/ but it looks like it is not reachable. Has Spring deprecated the support of Splunk?

Answer 1

The schema is not online, spring resolves it from the class path in the jar from META-INF/spring-schemas in the jar - if this is a runtime error, it appears you don't have the jar on the class path. If this error is just in an IDE (and not at runtime) you are using one that is not spring-aware - you can ignore the error in an IDE, use a spring-aware IDE, or use the IDE features to manually add the schema mappings.
