[JBoss JIRA] (TEIID-3841) sap-nw-gateway translator wrongly encodes when a parameter includes a space

by Steven Hawkins (JIRA)

[ https://issues.jboss.org/browse/TEIID-3841?page=com.atlassian.jira.plugin... ] Steven Hawkins resolved TEIID-3841. ----------------------------------- Resolution: Done The root issue turned out to be that we weren't encoding the parameters, so webclient was making assumptions about what the base address means. As a valid uri, the call works. With this particular example there is an issue with SAP reporting a time type for departureTime/arrivalTime, but returning an internal value. > sap-nw-gateway translator wrongly encodes when a parameter includes a space > --------------------------------------------------------------------------- > > Key: TEIID-3841 > URL: https://issues.jboss.org/browse/TEIID-3841 > Project: Teiid > Issue Type: Bug > Components: Misc.
