Hi,
The SparqlStmt API built against jena 3.14.0 is now available on Maven Central
[1] in case one want to give it a try (example in [2]) and give feedback and
whether one thinks it would be a useful contribution to Jena directly - and
what changes would be necessary if so.
<dependency>
<groupId>org.aksw.jena-sparql-api</groupId>
<artifactId>jena-sparql-api-stmt</artifactId>
<version>3.14.0-1</version>

Note that parsing the string as a query aborts early as soon as it finds an
update keyword so the cost of parsing isn't very large.

is there some utility function here in the code base now already to do
this, or do I still need to roll my own here?

Hi,
I would like to know if Jena offers a way to detect the type of an
unknow SPARQL request ?Starting from the query string.
At the moment the only way I succed to code it without "basic parsing"
of the query ( sort of thing I prefer avoid, manually parsing string with
short function often create errors )
looks like this :
[...]
String queryString = "a query string, may be a select or an
update";
try{
Query select = QueryFactory.create(queryString);
Service.process_select_query(select);//do some work with
the select
}
catch(QueryException e){
UpdateRequest update = UpdateFactory.create(queryString);
Service.process_update_query(update);//do some work with
the update
}
catch(ProcessException e){
//handle this exception
}
[...]
So is it possible ? Or not ?
Not currently.
You could use a regexp to spot the SELECT/CONSTRUCT/DESCRIBE/ASK keyword
coming after BASE/PREFIXES/Comments.
