Issues with metadata json callback and oauth implementation questions
Hi All,
Big thanks for all the support recieved from the mailing list. Looking
forward for a solution on this one too. I am using java version of shindig
incubating.
I am using '/gadgets/metadata?req={jsonrequestobject}' for constructing the
iframeurl for a gadget. I have integrated the opensocial directory available
at http://directory.opensocial.org/gadgets/directory to add gadgets to my
container. But shindig server fails to properly parse many of the gadget
xmls mentioned in the list with the following issues(each is different
gadgets)
1.java.lang.IllegalArgumentException: duplicate key: In_English_only
com.google.common.collect.ImmutableMap$RegularImmutableMap.<init>(ImmutableMap.java:587)
com.google.common.collect.ImmutableMap$RegularImmutableMap.<init>(ImmutableMap.java:555)
com.google.common.collect.ImmutableMap$Builder.fromEntryList(ImmutableMap.java:216)
com.google.common.collect.ImmutableMap$Builder.build(ImmutableMap.java:202)
org.apache.shindig.gadgets.spec.MessageBundle.parseMessages(MessageBundle.java:142)
org.apache.shindig.gadgets.spec.MessageBundle.<init>(MessageBundle.java:60)
org.apache.shindig.gadgets.DefaultMessageBundleFactory.fetchBundle(DefaultMessageBundleFactory.java:144)
org.apache.shindig.gadgets.DefaultMessageBundleFactory.getNestedBundle(DefaultMessageBundleFactory.java:110)
org.apache.shindig.gadgets.DefaultMessageBundleFactory.getBundle(DefaultMessageBundleFactory.java:78)
org.apache.shindig.gadgets.DefaultMessageBundleFactory.getParentBundle(DefaultMessageBundleFactory.java:126)
org.apache.shindig.gadgets.DefaultMessageBundleFactory.getNestedBundle(DefaultMessageBundleFactory.java:100)
org.apache.shindig.gadgets.DefaultMessageBundleFactory.getBundle(DefaultMessageBundleFactory.java:78)
org.apache.shindig.gadgets.variables.VariableSubstituter.substitute(VariableSubstituter.java:46)
org.apache.shindig.gadgets.process.Processor.process(Processor.java:84)
org.apache.shindig.gadgets.render.Renderer.render(Renderer.java:76)
org.apache.shindig.gadgets.servlet.GadgetRenderingServlet.render(GadgetRenderingServlet.java:58)
org.apache.shindig.gadgets.servlet.GadgetRenderingServlet.doGet(GadgetRenderingServlet.java:93)
it seems when shindig encounters a duplicate key while parsing the xmls
provied in the <Locale .../> tags, this occurs, I am wondering how to tackle
this? I am not sure, if i should modify shindig internals to fix this issue?
2. How can i find the views that are specifically supported by a particular
gadget as I have to add it to the request object while making the json
request?
Or is it that I need to replace the view='' value in the iframe section of
json response, with any of the values avaialable in the views section of the
same response, if they don't match.
3. My container doesn't yet support oauth, so many gadgets fail with
20:42:46,138 ERROR [STDERR] 24 Jul, 2009 8:42:46 PM
org.apache.shindig.gadgets.oauth.OAuthModule$OAuthCrypterProvid
er <init>
INFO: Using random key for OAuth client-side state encryption
20:42:46,170 ERROR [STDERR] 24 Jul, 2009 8:42:46 PM
org.apache.shindig.gadgets.oauth.OAuthModule$OAuthStoreProvider
loadDefaultKey
WARNING: Couldn't load OAuth signing key. To create a key, run:
openssl req -newkey rsa:1024 -days 365 -nodes -x509 -keyout testkey.pem \
-out testkey.pem -subj '/CN=mytestkey'
openssl pkcs8 -in testkey.pem -out oauthkey.pem -topk8 -nocrypt -outform
PEM
Then edit gadgets.properties and add these lines:
shindig.signing.key-file=<path-to-oauthkey.pem>
shindig.signing.key-name=mykey
I have found the following links
http://wiki.opensocial.org/index.php?title=Introduction_To_Signed_Requests
http://wiki.opensocial.org/index.php?title=Validating_Signed_Requests
http://cwiki.apache.org/confluence/display/SHINDIG/Enabling+OAuth+support
http://code.google.com/apis/orkut/docs/rest/developers_guide_protocol.html
I haven't gone through all of them, but please if someone clarify if these
contain accurate information to enable oauth support in my container, so
that gadgets that require oauth can run properly?
Sorry for this big post, comments are greatly appreciated.
Thanks and Best Regards,
Hafiz

This was fixed on trunk awhile ago:
