A web application is using the apache cxf client to send requests to a remote web service.
When this web application is deployed on Tomcat everything is OK.
The requests failed to be sent when this web application is deployed on JBOSS AND the size of the body (envelope) is greater than 8 KB; the error below got generated:
17:57:15,387 WARNING [org.apache.cxf.phase.PhaseInterceptorChain (ConnectorExecutor-21) Interceptor for xxx#{http://cxf.apache.org/jaxws/dispatch}Invoke has thrown exception, unwinding now: org.apache.cxf.interceptor.Fault: Could not send Message.

The HTTP stream mode seems to have switched to chunked.
What do you think of this first assumption?
It can be found in the official apache cxf documentation that it is possible to provide a spring configuration file in order to change the cxf client behavior.
What is the configuration file content?
回答1:
I answer to my own question, because after additional tests, the configuration described below worked for me.
First, the error was probably generated because the cxf client automatically switched to chunked transfer mode; indeed the configuration change described in this answer forces the cxf client to not use chunking and then requests get successfully sent with envelope size greater than 8 KB.
The cxf client behavior can be changed using a Spring configuration file, according to the official cxf apache documentation:
- https://cxf.apache.org/docs/client-http-transport-including-ssl-support.html
- https://cxf.apache.org/docs/configuration.html
There is no need to change the lines of code of the java client.
- 1- cxf configuration file
Create a cxf.xml spring configuration file:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:http-conf="http://cxf.apache.org/transports/http/configuration"
xmlns:jaxws="http://cxf.apache.org/jaxws"
xsi:schemaLocation="
http://cxf.apache.org/transports/http/configuration http://cxf.apache.org/schemas/configuration/http-conf.xsd
http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
<http-conf:conduit name="*.http-conduit">
<http-conf:client AllowChunking="false"/>
</http-conf:conduit>
</beans>
- 2- cxf.config.file.url java system property
Edit JBOSS batch or script files in order to add this system property to java command.
The value is the URL that points to cxf.xml file, a windows example is shown below:
-Dcxf.config.file.url=file:/C:/JBoss-7.1.1.Final/standalone/configuration/cxf.xml
There is below an example for Linux/UNIX:
-Dcxf.config.file.url=file:///home/jay/as/JBoss-7.1.1.Final/standalone/configuration/cxf.xml
- 3- Restart JBOSS
- 4- Test
- 5- Ignore the WARNING message generated when the request is sent
16:23:03,388 INFO [org.apache.cxf.bus.spring.ControlledValidationXmlBeanDefinitionReader] (ConnectorExecutor-1) Loading XML bean definitions from URL [file:/C:/JBoss-7.1.1.Final/standalone/configuration/cxf.xml]

I think that the NamespaceHandler for http://cxf.apache.org/transports/http/configuration XML schema namespace should be found because there is this jar below:
C:/JBoss-7.1.1.Final/modules/org/apache/cxf/main/cxf-rt-transports-http-2.4.6.jar
Anyway, the webservice request is successfuly sent !!
