This just in. bb-manifest.xml files will not upload to SaaS when the XML does not meet the standard: Extensible Markup Language (XML) 1.0 (Second Edition) .As we don't check this in Self and Managed-hosted systems, you may have had URLs in your bb-manifest.xml file using the following format:

<url value="itemanalysis/showItemAnalysis?action=display&;course_id=@X@course.pk_string@X@" />


These should be written as follows because the & character in XML must be encoded:

<url value="itemanalysis/showItemAnalysis?action=display&amp;course_id=@X@course.pk_string@X@" />

I’m writing this to let you know that we’ve run into a new issue with the SAML B2 on a few Learn systems that then causes problems for other B2s that make outbound connections from Learn. We're still working to determine the Learn & SAML B2 versions affected. To date we've seen this on a Q2 2016 system with the 3000.1.0 version of SAML, and a SaaS 3100.9 system running version 3100.9 of SAML.


If the lines shown below are found in the stdout-stderr logs, please open a ticket using your Behind the Blackboard account, include the logs, the Learn version, and the version of the SAML authorization B2. Reference LRN-121348 early in the case description so that support is aware that this is a known issue. While you're on Behind the Blackboard, be sure to subscribe to the Learn support bulletins (Top menu, My Account, MY SUBSCRIPTiONS).


Here are the lines your will see in the stdout-stderr files on an affected system; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'keyManager' defined in ServletContext resource [/WEB-INF/config/saml/securityContext.xml]: Invocation of init method failed; nested exception is java.lang.RuntimeException: Unable to load aliases from keyStore


There may be other exceptions that the SAML B2 throws that will cause the issue. The above is one example. The main point is that for this issue to occur the SAML B2 must throw an exception and stop running.


... then later in the log file ...

INFO   | jvm 2    | < information about your B2 wil be here>  threw exception [Handler dispatch failed; nested exception is java.lang.NoClassDefFoundError: org/apache/commons/httpclient/params/HttpConnectionParams] with root cause

INFO   | jvm 2    | 2017/02/15 18:55:54 | java.lang.NoClassDefFoundError: org/apache/commons/httpclient/params/HttpConnectionParams

INFO   | jvm 2    | 2017/02/15 18:55:54 |     at

INFO   | jvm 2    | 2017/02/15 18:55:54 |     at


The main point of the above is that we can see that your B2 threw an error because the system was incorrectly handing it the SAML socket factory.
