>
> Key: AXIS-2142
> URL: http://issues.apache.org/jira/browse/AXIS-2142
> Project: Apache Axis
> Type: Bug
> Versions: current (nightly)
> Environment: Axis 1.2 CVS using GNU classpathx javamail and activation
> implementations with Sun JDK 1.4.2_06
> Reporter: Archit Shah
> Attachments: DH.patch
>
> When running the Axis (not Axis2) CVS tip with javamail and activation
> implementations from GNU classpathx, two tests fail with ClassCastExceptions.
> These failures are due to incorrect use of DataHandlers. The failing tests
> are:
> test.wsdl.interop4.groupG.dime.rpc.DimeRPCInteropTestCase
> #test2DimeRPCSoapPortEchoAttachments
> test.wsdl.interop4.groupG.mime.rpc.MimeRPCInteropTestCase
> #test2MimeRPCSoapPortEchoAttachments
> And the stack trace is:
> java.lang.ClassCastException
> at org.apache.axis.utils.JavaUtils.convert(JavaUtils.java:325)

> The convert method of org.apache.axis.utils.JavaUtils relies on the
> getContent method of javax.activation.DataHandler to get an InputStream for
> the data, twice doing the following:
> in = (InputStream)handler.getContent();
> instead of:
> in = handler.getInputStream();
> Calling getContent and casting to InputStream is not guaranteed to work. The
> Javadoc for the getContent method specifies "If no DataContentHandler can be
> found for the the type of this data, the DataHandler returns an InputStream
> for the data." Therefore, the cast can fail if a DataContentHandler is
> installed. I ran into this exceptions because the GNU javamail
> implementation has a DataContentHandler for the MIME type
> application/octet-stream and getContent returns a byte array instead of the
> input stream.
> Casting the return value of getContent is also done in another context.
> JavaUtils and SourceDataHandlerDeserializer both do:
> StreamSource ss = new StreamSource(new StringReader(
> (String) dh.getContent()));
> when the following would suffice:
> StreamSource ss = new StreamSource(dh.getInputStream());
