Good point. We will end up with ugly and backward incompatible URIs. What about introducing "implicit URI encoding" term? Can't we just assume that semi-URIs strings passed to the Camel DSLs are in fact decoded URIs? In such case: import org.springframework.web.util.UriUtils; // Decoded URI passed to the component. String decodedUri = "file://inbox?expression=backup/${date:now:yyyyMMdd}/${file:name}"; // If we encode this URI we will end up with valid URI: // file://inbox?expression=backup/$%7Bdate:now:yyyyMMdd%7D/$%7Bfile:name%7D String encodedUri = UriUtils.encodeUri(decodedUri, "UTF-8"); Maybe we just could validate that URI passed to the component is valid AFTER encoding it? String decodedUriFromDsl = ... String encodedUri = UriUtils.encodeUri(decodedUriFromDsl, "UTF-8"); assertValidUri(encodedUri); This will guarantee that Camel uses valid URIs but won't break contract of many existing components. -- Henryk Konsek http://henryk-konsek.blogspot.com
