Hi,
In the process of addressing NUTCH-1273 [0] I ran into a small problem with
some Tika classes.
The patch I attached to the issue currently upgrades usage of external
dependencies bar Tika. You will therefore still see javac flagging up
problems within o.a.n.util.MimeUtil#autoResolveContentType [1]
// if returned null, or if it's the default type then try url resolution
168 if (type == null 169 || (type != null &&
type.getName().equals(MimeTypes.OCTET_STREAM))) { 170 // If no mime-type
header, or cannot find a corresponding registered 171 // mime-type, then
guess a mime-type from the url pattern 172 type =
this.mimeTypes.getMimeType(url) != null ? this.mimeTypes 173 .getMimeType(url)
: type; 174 }
Initially I tried changing the above to
// if returned null, or if it's the default type then try url resolution
if (type == null
|| (type != null && type.getName().equals(
MimeTypes.OCTET_STREAM))) {
// If no mime-type header, or cannot find a corresponding registered
// mime-type, then guess a mime-type from the url pattern
String mt = tika.detect(url);
type = mt != null ? mt : type;
}
However after compiling I get
[javac] MimeUtil.java:165: incompatible types
[javac] found :
java.lang.Object&java.io.Serializable&java.lang.Comparable<? extends
java.lang.Object&java.io.Serializable&java.lang.Comparable<?>>
[javac] required: org.apache.tika.mime.MimeType
[javac] type = mt != null ? mt : type;
[javac] ^
This is because Tika.detect(URL) returns the mimetype as a String and the
detectors themselves return a MediaType.
I went to user@tika and the feedback I got was
* Switch your code to use a mimetype String
* Switch your code to use MediaType rather than MimeType, and call
DefaultDetector directly (rather than using the Tika facade class)
* If you get back a String (not null) for the mimetype, create a MimeType
object for it.
So I suppose my question is what do we want too do?
Thanks
