Hi all
I’m new at thredds - and diving straight into attempting to get data from a
thredds server to appear on worldwindserver.net. I’m failing at googling up a
result, so I hope this hasn’t been covered somewhere here recently.
if I try to add a server at worldwindserver.net with the form:
http://ip.address/thredds/wms/gb6/ocean_eta_1993_03.nc?service=WMS&version=1.3.0&request=GetCapabilities
….worldwindserver.net tells me 'Failed to retrieve WMS capabilities from
[URL]:….’.
I’ve been pursuing the line that it may be a CORS issue, so I’ve followed
Apache’s instructions and added the following to webxml:
---
<filter>
<filter-name>CorsFilter</filter-name>
<filter-class>org.apache.catalina.filters.CorsFilter</filter-class>
<init-param>
<param-name>cors.allowed.methods</param-name>
<param-value>GET</param-value>
</init-param>
<init-param>
<param-name>cors.exposed.headers</param-name>
<param-value>Access-Control-Allow-Origin,Access-Control-Allow-Credentials</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CorsFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
---
…and enabled the CORS element in threddsConfig.xml:
---
<CORS>
<enabled>true</enabled>
<maxAge>1728000</maxAge>
<allowedMethods>GET</allowedMethods>
<allowedHeaders>*</allowedHeaders>
<allowedOrigin>*</allowedOrigin>
</CORS>
---
(set allowedHeaders to *, not sure if this is advisable or correct!)
However, the result from worldwindserver.net is unchanged.
Also - using this service: http://client.cors-api.appspot.com/client
…tells me that CORS is not enabled on my thredds catalogue.
Tomcat is hard restarted after both changes, I’m wondering if there is anywhere
else I should look, or make changes.
…or, does anyone have a thredds catalogue which is successfully serving WMS
data to worldwindserver, and is happy to share bits of config files?
Thanks
Adam
