[jira] Created: (AXIS2-4726) Partial Base64Binary data when
underlying XML parser does not coalesce text
Partial Base64Binary data when underlying XML parser does not coalesce text
---------------------------------------------------------------------------
Key: AXIS2-4726
URL: https://issues.apache.org/jira/browse/AXIS2-4726
Project: Axis2
Issue Type: Bug
Affects Versions: 1.5.1
Reporter: Myles Bunbury
After running wsdl2java.sh, the following code snippet was produced for Base64Binary.parse(XMLStreamReader):
---
if (isReaderMTOMAware(reader)
&&
java.lang.Boolean.TRUE.equals(reader.getProperty(org.apache.axiom.om.OMConstants.IS_BINARY)))
{
//MTOM aware reader - get the datahandler directly and put it in the object
object.setBase64Binary(
(javax.activation.DataHandler) reader.getProperty(org.apache.axiom.om.OMConstants.DATA_HANDLER));
} else {
if (reader.getEventType() == javax.xml.stream.XMLStreamConstants.START_ELEMENT && reader.getName().equals(new javax.xml.namespace.QName(org.apache.axiom.om.impl.MTOMConstants.XOP_NAMESPACE_URI, org.apache.axiom.om.impl.MTOMConstants.XOP_INCLUDE)))
{
java.lang.String id = org.apache.axiom.om.util.ElementHelper.getContentID(reader, "UTF-8");
object.setBase64Binary(((org.apache.axiom.soap.impl.builder.MTOMStAXSOAPModelBuilder) ((org.apache.axiom.om.impl.llom.OMStAXWrapper) reader).getBuilder()).getDataHandler(id));
reader.next();
} else if(reader.hasText()) {
//Do the usual conversion
java.lang.String content = reader.getText();
//Bug is below
object.setBase64Binary(
org.apache.axis2.databinding.utils.ConverterUtil.convertToBase64Binary(content));
}
}
---
In the last 'else if' block, 'object.setBase64Binary' is called. However, if the XMLStreamReader is not coalescing, then multiple text nodes can be encountered as this block of code is looped through via the encapsulating while loop (not shown). With each pass through the loop, old data is overwritten. The entire text needs to be collected first before calling convertToBase64Binary().
The other branches of the conditional statements are likely vulnerable to the same problem.

------------------------------------
Fix Version/s: 1.6
Resolution: Fixed
The way ADB handles MTOM and base64 has been completely revised and this issue should no longer occur with the current trunk.

[jira] Resolved: (AXIS2-4726) Partial Base64Binary data when

Posted by "Andreas Veithen (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/AXIS2-4726?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Andreas Veithen resolved AXIS2-4726.
------------------------------------
Fix Version/s: 1.6
Resolution: Fixed
The way ADB handles MTOM and base64 has been completely revised and this issue should no longer occur with the current trunk.
