JCA FTP Adapter limited to 4MB in OSB

Problem:

If you are using the FTPAdapter with OSB 11g (specifically 11.1.1.7), you may experience the following Java exception in the osb_server1.out log file:

####<Oct 29, 2014 3:04:41 AM EDT> <Warning> <JCA_FRAMEWORK_AND_ADAPTER> <soahost1> <osb_server1> <[STUCK] ExecuteThread: '1' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <0000K^N1fyV8t1RMyYqYMG1JKBeB0000uE> <1413443141803> <BEA-000000> <onReject: The resource adapter 'FTP Adapter' requested handling of a malformed inbound message. However, the following activation property has not been defined: 'rejectedMessageHandlers'. Please define it and redeploy. Will use the default Rejection Directory file://jca/Get/rejectedMessages for now.>

Solution:

The default properties in the JCA FTP Adapter limits files to 4MB when polling for inbound messages.

1. Edit the FTPAdapter and add the following property:

<property name="SupportsScalableDOM" value="false"/>
