Hi,
I was doing some testing with SLP (java API 1.0, SLP 1.2.1). I wrote a
fairly simple program which registers a dummy service with one
attribute, this attribute is a comma delineated string.
When I use slptool (or a C program) to register it works as expected:
$ slptool.bat register service:foo:http://192.168.5.113:2268
"(Attribute=one,two,three)"
$ slptool findattrs service:foo:http://192.168.5.113:2268
(Attribute=one,two,three)
Now doing the same thing with the Java API results in the following:
$ slptool findattrs service:foo:http://192.168.5.113:2268
(Atrribute=one\2ctwo\2cthree)
Notice the ',' have been converted to '\2c'. The issue can be duplicated
with the "Register" Java example.
What I believe is happening is that the Java API is calling
ServiceLocationAttribute.escapeString before sending the data over the
wire (RFC 2165 section 17.1.1) but the server is not un-escaping it
and/or the client is also not un-escaping the value. The resulting
registration is not valid for clients that need to examine the attributes.
Is this a known issue? Is there a work-around?
Thank you
