Ron,

Could please close your bug report in the Apache Chemistry JIRA (this still is 
a Weblogic bug;-)) and open an improvement issue for a Weblogic version?
I will tackle it as soon as I can, so that we can include it into the OpenCMIS 
0.8.0 release. For the time being, I hope you can survive with your "custom 
build".


- Florian

> JAX-WS is not designed to handle huge messages. The JAX-WS interfaces force 
> in some situation (handling SOAP headers, etc.) a JAX-WS implementation to 
> keep the whole message in memory. That works fine with a small amount of data 
> but fails in a content management use-case when huge documents should be 
> transferred. OpenCMIS can handle documents that are much larger than the 
> available main memory by streaming the content. We avoid all circumstances 
> that require that the message must be loaded in main memory.
> 
> All JAX-WS implementers are aware of these shortcomings and all JAX-WS stacks 
> provide workarounds and proprietary interfaces to overcome these problems. 
> Since they are all different, we had to settle on one stack. When we started 
> OpenCMIS in 2009 we knew from previous projects that the Sun stack could do 
> what we need.
> 
> Later there was a demand for a Web Sphere version that uses Web Spheres 
> proprietary extensions. So we build it.
> 
> We know that OpenCMIS has been used with Weblogic, but we never heard of the 
> problem that you have reported. If you are willing to help us testing (I 
> don't have access to a Weblogic server), we could also build a Weblogic 
> version of OpenCMIS.
