Hello Ajith, thank you for responding =3D)

WSDL4J picks up the relative path just fine.
The problem is that a relative file path in a application server environmen=
t is not predictable.

Consider this (I use tomcat as example):
If I start Tomcat from c:\tomcat\bin and then in a servlet (located in say =
"c:\tomcat\webapps\axis2") execute the code  "new File("../schemas/somesc=
hema.xsd").toURL();" I will get "file:/C:/tomcat/bin/../schemas/someschem=
a.xsd"=20

Looking at the WSDL4J source (not sure if I'm looking at the right version =
though) and judging by the error message I get it seems that this is what=
 happens when Axis2 parses my wsdl.

As the base URI in this case is not predictable (depends on the servlet con=
tainer/application server and how it is started) I have no chance to plac=
e the schemas in a location that they will get picked up by WSDL4J unless=
 I can somehow specify this location.

The relative path must work both for WSDL4J parsing the wsdl server-side in=
 Axis2 and publicly for a consumer of my webservice (relative to the ?wsd=
l url).

I would not mind having to duplicate the schema files (two locations) as lo=
ng as they are all located inside my webapp folders.

Perhaps this could be solved by axis2 specifying a base URI for relative im=
ports?

Best Regards,
Johan Andersson

Hi,
Hmmm.. WSDL4J has a method that allows it to use a given base uri  but
I'm not sure whether this is the problem. I mean wsdl4j is perfectly
capable of picking up schemas from relative uri's.
I'll try to test this scenario in a test case and let you know.
