[jira] Created: (AXIS2-4363) Classcast exception when enabling MTOM
with ADB
Classcast exception when enabling MTOM with ADB
------------------------------------------------
Key: AXIS2-4363
URL: https://issues.apache.org/jira/browse/AXIS2-4363
Project: Axis 2.0 (Axis2)
Issue Type: Bug
Affects Versions: 1.4.1
Environment: ADB databinding
Reporter: Julien Henry
When enabling MTOM and generating client stub with ADB, I get the following error:
{code}
java.lang.ClassCastException:
org.apache.axiom.om.util.OMXMLStreamReaderValidator cannot be cast to org.apache.axiom.om.impl.llom.OMStAXWrapper
at com.xxx.vaultwebservice.client.Vault_WebServiceStub$XXXBundleType$Factory.parse(Vault_WebServiceStub.java:21236)
at com.xxx.vaultwebservice.client.Vault_WebServiceStub$DownloadXXXResponse$Factory.parse(Vault_WebServiceStub.java:56454)
at com.xxx.vaultwebservice.client.Vault_WebServiceStub.fromOM(Vault_WebServiceStub.java:64390)
{code}
This error only occurs when log level for org.apache.axiom is DEBUG so a workaround is to set log level > DEBUG.
The bug is also present with staged 1.5 version.

[jira] Commented: (AXIS2-4363) Classcast exception when enabling
MTOM with ADB
Posted by "Andreas Veithen (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/AXIS2-4363?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12715696#action_12715696 ]
Andreas Veithen commented on AXIS2-4363:
----------------------------------------
The problem is caused by the fact that some parts of Axis2 code directly use org.apache.axiom.om.impl.llom.OMStAXWrapper. This needs to be changed so that the code refers to the corresponding interface(s), i.e. OMXMLStreamReader and OMAttachmentAccessor. There are actually several reasons for this:
1. If the log level is set to DEBUG, OMElementImpl#getXMLStreamReader wraps the OMStAXWrapper in a OMXMLStreamReaderValidator. This causes the issue described above.
2. org.apache.axiom.om.impl.llom.OMStAXWrapper is part of axiom-impl (the LLOM implementation of Axiom), but Axis2 should ideally only refer to axiom-api.
3. It's against the programming-to-interface paradigm.
4. In Axiom trunk, OMStAXWrapper has been merged with the corresponding class from the DOOM implementation and now lives in axiom-api (as org.apache.axiom.om.impl.OMStAXWrapper). org.apache.axiom.om.impl.llom.OMStAXWrapper still exists, but only for compatibility reasons. It would be great if we could eliminate it on the longer term.
Files in Axis2 that refer to org.apache.axiom.om.impl.llom.OMStAXWrapper:
modules/adb/src/org/apache/axis2/databinding/types/soapencoding/Base64Binary.java
modules/adb/src/org/apache/axis2/databinding/types/xsd/Base64Binary.java
modules/adb/src/org/apache/axis2/databinding/utils/ConverterUtil.java
modules/adb-codegen/src/org/apache/axis2/schema/template/ADBBeanTemplate.xsl -> this means that wsdl2java generates code that refers to org.apache.axiom.om.impl.llom.OMStAXWrapper
