Hi,
I developed sample POJO web service (code-first, WSDL is generated by
Axis2), and enabled MTOM and caching in services.xml descriptor.
However, I get OutOfMemoryError on the server side. Logging revealed
that parameter "cacheAttachments" stated in service.xml descriptor is
not taken into account. Is this a known problem with POJO web services?
Should I create an issue for this problem?
I'm using Axis2 1.6.1, Tomcat 7.0.22, Oracle/Sun Java 1.6.0_24, Tomcat
starts with -Xmx512m, and test file size for sending is about 500MB.
Detailed infromation below.
Regards,
Ognjen
