The exception may also be caused because Jersey does not know what to
do with the SearchQuery type i.e. it does not know how to convert a
String instance to a SearchQuery instance. Without looking at
SearchQuery source i cannot say for sure.
There are certain rules for converting String instances:
https://jersey.dev.java.net/nonav/documentation/latest/user-guide.html
#d4e226
Jersey also support extension to those described in the above link:
https://jersey.dev.java.net/nonav/apidocs/latest/jersey/com/sun/jersey/spi/StringReaderProvider.html
So you can define a StringReaderProvider instance for converting a
String instance to a SearchQuery instance e.g.:
@Provider
public class MyProvider implements
StringReaderProvider<SearchQuery> {
public StringReader<SearchQuery> getStringReader(Class<?> type,
Type genericType, Annotation[] annotations) {
if (type == SearchQuery.class) {
StringReader<SearchQuery> sr = ...
return sr;
} else {
return null
}
}
}
