How to resolve "java.lang.AbstractMethodError: javax.ws.rs.core.UriBuilder.uri(Ljava/lang/String;)" exception

Operation Systems: All

The "Invoke REST API" need to call a public abstract method UriBuilder uri(java.lang.String uriTemplate) in the class javax.ws.rs.core.UriBuilder. For this to work, a subclass that implements this method must be available. The error indicates unavailability of implementation.

This subclass should be provided by "javax.ws.rs-api-2.0.1.jar" under TIBCO_HOME/bw/plugins/lib. However, sometimes a similar subclass with implementation was getting loaded from TIsforce.jar, which is part of TIBCO TPCL(TIBCO_HOME/tpcl/TPCL_Version/jdbc). 

Although in TIsforce.jar, the "tibcosoftwareinc.sforce.externals.org.apache.cxf.jaxrs.impl.UriBuilderImpl" is a subclass of "javax.ws.rs.core.UriBuilder", it doesn't include the aforementioned method and hence the class "tibcosoftwareinc.sforce.externals.org.apache.cxf.jaxrs.impl.UriBuilderImpl" doesn't provide implementation for the same. 

To resolve the issue, we can put the TPCL path (TIBCO_HOME/tpcl/TPCL_Version/jdbc) at the end of classpath in TRA file. If it doesn't work, then we can try to backup and remove the TIsforce.jar in the TIBCO_HOME/tpcl/TPCL_Version/jdbc folder.
