no object DCH for MIME type application/atom+xml

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Download mail.jar and activation.jar from Sun per instructions and put
in classpath
2. Upload a photo using PicasawebService.insert
3.

What is the expected output? What do you see instead?

Expected a PhotoEntry but got this exception:

javax.activation.UnsupportedDataTypeException: no object DCH for MIME type
application/atom+xml
    at javax.activation.ObjectDataContentHandler.writeTo(DataHandler.java:870)
    at javax.activation.DataHandler.writeTo(DataHandler.java:301)
    at javax.mail.internet.MimeBodyPart.writeTo(MimeBodyPart.java:1403)
    at javax.mail.internet.MimeBodyPart.writeTo(MimeBodyPart.java:874)
    at javax.mail.internet.MimeMultipart.writeTo(MimeMultipart.java:444)
    at com.google.gdata.client.media.MediaService.insert(MediaService.java:293)

This happens even if I add an explict call to
MediaMultipart.loadMimeMappings();

What version of the product are you using? On what operating system?

After a frustrating couple of days I found that this problem only rears its 
ugly head
in java 6.  I switched to java version "1.5.0_16"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_16-b02)
Java HotSpot(TM) Server VM (build 1.5.0_16-b02, mixed mode) and the problem 
went away.
Everything else was the same except for the java version.  Weird.

Weird. Which version of Java Activation Framework did you see this issue on?  I
believe the latest one is 1.1.1.

I have been using jaf-1.1.1 and javamail-1.4.1

There was an issue in V1.22 of the Java client when uploading.  The latest 
version of
the Java client contains a NO_CHUNKED_MEDIA_REQUEST property on MediaService 
which
allows you to disable chunked requests if they are causing issues.  Please 
check if
that helps the issue, and refile a bug if it does not.

I still get this error even with the following line. I didn't try with Java 1.5.

        myService.setChunkedMediaUpload(MediaService.NO_CHUNKED_MEDIA_REQUEST);

java 1.6.0_11
gdata java client lib 1.30.0
jaf 1.1.1
javamail 1.4.2

I am still getting this error on Ubuntu 9.04 with gdata framework v1.35.
java -version
java version "1.6.0_14"
Java(TM) SE Runtime Environment (build 1.6.0_14-b08)
Java HotSpot(TM) Server VM (build 14.0-b16, mixed mode)
I have tried with activation.jar 1.1.1 on the classpath and off the 
classpath(as I
understand it is part of the Java 6 now). Still same problem.  Any ideas what 
could
be wrong?  I still have no problem with Java 5.

bigwynnr,

Sounds like some kind of classpath issue.

1. Can you check if you are loading the activation.jar lib from java 1.6 
framework or
from a third_party location included in CLASS_PATH?
2. Are you using the jars from the downloaded package (compiled in java 5) or 
are
these jars came from recompiling the source code locally (java 6)?

Ok i tried with jaf 1.1.1 activation framework jar as well in java 6.  Didnt 
run into
any problem.  Looks mostly like you are using a different JAF jar.  Please 
re-confirm
that the jaf that is loaded is the right one.

I run into this error in a different context.  I have a Java application that 
does 
different things using the Doc List Data API.  This app has a method that 
uploads 
files to my Google Docs.  It works fine from Java.  When I try to call the same 
method from R using the rJava bridge I get the exception "Exception: no object 
DCH 
for MIME type application/atom+xml". 

The arguments I pass in both cases are the same strings.  I have about 30 java 
methods that I call successfully in the R code but this one fails.  I'm using 
the 
same jars in both cases.  Cannot figure out why it fails from R.

I probably should have mentioned that I am calling this method in the context 
of a fuse 
filesystem which is interfaced through the fuse-j library (uses jni).  That 
might be 
causing classloader problems somehow.

Ryan,
   It looks like the MIME mappings are not loaded correctly when run inside your
environment.  These are loaded statically in 
http://code.google.com/p/gdata-java-client/source/browse/trunk/java/src/com/goog
le/gdata/data/media/MediaMultipart.java
 using loadMimeMappings() method.

Can you explicitly call MediaMultipart#loadMimeMappings in your code 
initialization
and see if that helps?

A year later I finally figured out how to fix this issue.  Since 
activation.jar's
classes are now in rt.jar (the bootclasspath) since java 6, I needed to 
explicitly
set the context classloader before any google api call that needed the custom 
mime
mappings.  This is because fuse-j was triggering api calls in a new thread which
evidently had the context classloader set such that the data handlers were
accessible.  This was not an issue in java 5 since activation.jar was on the
bootclasspath.  Please close this issue it is working for me now.  Not sure if 
it
makes sense to attempt to fix this inside the google libraries so that people 
like me
won't run into this problem.  Thank you for your help!

Like one of the previous commenters, I have simple Java application that uploads
documents using the Documents List Data API. The application works fine when I 
run it
as a standalone application. However, when I run it inside Matlab, I get the
"javax.activation.UnsupportedDataTypeException: no object DCH for MIME type
application/atom+xml" error. Matlab is using the same version of Java and all 
the
necessary JAR files are loaded, but problems arise in the Matlab environment 
for some
reason (Matlab otherwise integrates with Java quite seamlessly).
