Hi there,
I am trying to build a simple disseminator that uses the imagemanip
servlet shipped with Fedora. I am building the SDep object using EZService.
This is my EZXML:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE ezdep [
<!ENTITY fedora "http://localhost:8080/";>
<!ENTITY imgmanip "http://localhost:8080/imagemanip/";>
]>
<sdep pid="AICTEST:SDepImg" label="Service Deployment for all image
resources">
<cmodel>AICTEST:CMImg</cmodel>
<sdef>AICTEST:SDefImg</sdef>
<impl method="getThumbnail">
<datastream-input datastream="MASTER"/>
<url-pattern>
&imgmanip;ImageManipulation?url=(MASTER)&op=resize&newWidth=128
</url-pattern>
</impl>
<impl method="getIntLarge">
<datastream-input datastream="MASTER"/>
<url-pattern>
&imgmanip;ImageManipulation?url=(MASTER)&op=resize&newWidth=1024
</url-pattern>
</impl>
<impl method="getIntSmall">
<datastream-input datastream="MASTER"/>
<url-pattern>
&imgmanip;ImageManipulation?url=(MASTER)&op=resize&newWidth=300
</url-pattern>
</impl>
</sdep>
So far so good, not too different from the Fedora demos. The only
difference is that MASTER is a managed datastream, not an external
reference.
If I try to access the above methods, I get an error:
javax.servlet.ServletException: Could not load image:
http://localhost:8080/fedora/getDS?id=2013-07-10T17:40:56.66:1+(MASTER).
Errorcode 500 from remote server.

I haven't seen any documentation for the API method getDS, so I'm at a
loss about checking whether the DS ID being passed is correct.
Any hints?
Thanks,
