Help needed on http methods and regular expressions
Chris Cardona has been trying to test the jacc 1.1 extended http-
method support by deploying slide (GERONIMO-1747) and I don't know
enough about regular expressions to see where the problem is.
The http 1.1 spec says:
(5.1.1) extension-method = token
(2.2)
token = 1*<any CHAR except CTLs or separators>
separators = "(" | ")" | "<" | ">" | "@"
| "," | ";" | ":" | "\" | <">
| "/" | "[" | "]" | "?" | "="
| "{" | "}" | SP | HT
CHAR = <any US-ASCII character (octets 0 - 127)>
CTL = <any US-ASCII control character
(octets 0 - 31) and DEL (127)>
I think this means a hyphen is allowed in an extension-method.
The web-app 2.5 schema says:
<xsd:simpleType name="http-methodType">
<xsd:annotation>
<xsd:documentation>
A HTTP method type as defined in HTTP 1.1 section 2.2.
</xsd:documentation>
</xsd:annotation>
<xsd:restriction base="xsd:token">
<xsd:pattern value="[\p{L}-[\p{Cc}\p{Z}]]+"/>
</xsd:restriction>
</xsd:simpleType>
I have roughly no clue what that means.
Xmlbeans is complaining:
cvc-datatype-valid.1.1: string value 'VERSION-CONTROL' does not match
patter
n for http-methodType in namespace http://java.sun.com/xml/ns/javaee,
error: cvc
-datatype-valid.1.1: string value 'BASELINE-CONTROL' does not match
pattern for
http-methodType in namespace http://java.sun.com/xml/ns/javaee]
I see 3 possiblilites:
1. I'm wrong and http 1.1 spec does not allow hyphens in extension
methods
2. sun is wrong and the regexp in http-methodType means something
other than the definition in the http 1.1 spec
3. xmlbeans is wrong and is not interpreting the regexp in the schema
correctly.
Anyone have a clue?
Help!
thanks

Whoop. My bad. Now I'm just as confused as you.

I'm kinda confused here. According to http://www.asciitable.com/
hyphen is 45 which is not in your list of exclusions, not a control
character, and I might be blind but I don't see it in the http spec
list of separators. Why exactly is hyphen not allowed?

It means hypen is not allowed. I.e. ascii 0-127 is allowed except
0-31,32,34,40,41,44,47,58,59,60,61,62,63,64,91,92,93,123,125

I talked with Greg Wilkins a bit and this issue is apparently going
to be fixed "soon":
http://jcp.org/aboutJava/communityprocess/maintenance/jsr154/
servlet-2.5_MR6.html
after checking that the last batch of xsd changes didn't break
anything I'm going to patch the web-app schema and re-push the
xmlbeans schema jar.

It looks to me like the regex in the schema file does not quite match
the HTTP spec. First, the regex in the schema file does not allow
numbers (the HTTP spec does), and second it also allows for
non-english characters (the HTTP spec does not). The regex basically
allows Unicode letters only (see all L* categories on
http://www.fileformat.info/info/unicode/category/index.htm).
I think that regex should be something like:
[\u0021-\u007E-[\(\)<>\{\}@,:;\[\]\?\\/]]+
