What steps will reproduce the problem? 1. Take a google group that needs authentication like "Tips4Trade" 2. Take the atom feed: "https://groups.google.com/group/Tips4Trade/feed/atom_v1_0_msgs.xml" 3. Follow steps in section "How to use the library on not-yet-supported services" of user guide 4. Error while doing "val f = s.query(feed, atomFeed.feedPickler)" What is the expected output? What do you see instead? Expected output should be a list of entries (works for public group feeds) Instead I get this error: [Fatal Error] :35:6: The string "--" is not permitted within comments. Exception in thread "main" java.lang.ExceptionInInitializerError at tmp.Test.main(Test.scala) Caused by: org.xml.sax.SAXParseException: The string "--" is not permitted within comments. at com.sun.org.apache.xerces.internal.parsers.AbstractSAXParser.parse(Unknown Source) at com.sun.org.apache.xerces.internal.jaxp.SAXParserImpl$JAXPSAXParser.parse(Unknown Source) at javax.xml.parsers.SAXParser.parse(Unknown Source) at scala.xml.parsing.FactoryAdapter.loadXML(FactoryAdapter.scala:292) at scala.xml.parsing.NoBindingFactoryAdapter.loadXML(NoBindingFactoryAdapter.scala:60) at scala.xml.XML$.load(XML.scala:64) at com.google.xml.combinators.LinearStore$.fromInputStream(LinearStore.scala:186) at com.google.gdata.client.GDataRequest.unpickle(GDataRequest.scala:131) at com.google.gdata.Service.query(Service.scala:109) at com.google.gdata.Service.query(Service.scala:96) at tmp.Test$.<init>(Test.scala:14) at tmp.Test$.<clinit>(Test.scala) ... 1 more What version of the product are you using?

Here is the file.

This is weird, this file is successfully parsed on my machine. Can you try the
following, in the Scala interpreter:
scala> val input = LinearStore.fromFile("atom_v1_0_msgs.xml")
scala> import com.google.gdata.data._
import com.google.gdata.data._
scala> val feed = new StdAtomFeed
feed: com.google.gdata.data.StdAtomFeed = com.google.gdata.data.StdAtomFeed@4078ee
scala> feed.feedPickler.unpickle(input)
res4: com.google.xml.combinators.Picklers.PicklerResult[feed.Feed] =

If that works, try to get the messages that were breaking the library in the first
place, and save that file. I assume it is the content of some message in the group
that is incorrectly encoded.

Well, your steps worked for me also. But the actual code doesn't. So I created a
dummy account with membership of this group (will mail you username/password in
separate mail). Here is my snippet:
import com.google.gdata.Service
import com.google.gdata.data.StdAtomFeed
object GData1 extends Application {
val s = new Service("comp-test-1.0", "cp") {}
s.setUserCredentials("USER", "PASSWORD")
val atomFeed = new StdAtomFeed
val feed = "http://groups.google.com/group/Tips4Trade/feed/atom_v1_0_msgs.xml"
val f = s.query(feed, atomFeed.feedPickler)
println(f.entries.head)
}

Ok, it looks like a xerces bug: http://issues.apache.org/jira/browse/XERCESJ-477 http://issues.apache.org/jira/browse/XERCESJ-520 I'm not sure yet if there are any workarounds, I will keep looking. |
