Akitoshi Yoshida updated AXIS-2658:
-----------------------------------
Attachment: OctetStreamDataSource.zip
> OctetStreamDataSource with an arbitrary content type
> ----------------------------------------------------
>
> Key: AXIS-2658
> URL: https://issues.apache.org/jira/browse/AXIS-2658
> Project: Axis
> Issue Type: Improvement
> Components: Basic Architecture
> Affects Versions: 1.4
> Environment: JDK 1.4.2
> Windows XP
> Reporter: Akitoshi Yoshida
> Priority: Minor
> Fix For: 1.4
>
> Attachments: OctetStreamDataSource.zip
>
>
> We would like to have a message ( org.apache.axis.Message ) that we can
> serialize (i.e., using its writeTo(OutputStream) method) more than once.
> We noticed that when attachments are instantiated with the
> org.apache.axis.attachments.ManagedMemoryDataSource class, they will be
> removed after serialization in the writeContentToStream(java.io.OutputStream
> os) method of org.apache.axis.attachments.AttachmentsImpl class. When this
> message is serialized again, it results in an IOException (not thrown but
> logged) saying that the resource is deleted.
> If the org.apache.axis.attachments.OctetStreamDataSource class can be changed
> to take a variable content type, we can use this data source class to replace
> those attachments in a handler.
> This will look like:
> ...
> private String contentType;
> ...
> public OctetStreamDataSource(String name, OctetStream data) {
> this(name, CONTENT_TYPE, data);
> }
> public OctetStreamDataSource(String name, String contentType, OctetStream
> data) {
> this.name = name;
> this.contentType = contentType;
> this.data = data == null ? null : data.getBytes();
> os = new ByteArrayOutputStream();
> } // ctor
> ...
> public String getContentType() {
> return contentType;
> } // getContentType
