Sentinel error when importing Solution Pack

When trying to import a Solution Pack into Sentinel an error is thrown at the end of the import.

There is a call being made to the graphical environment libraries on the system that is failing when the main Sentinel Server does not have a graphical environment installed.  The call is made to the java.awt.Toolkit.getDefaultToolkit class which fails unless the libraries are installed.  This has only shown up on a 64-bit machine that does not have any of the X libraries installed.  The system without the X libraries is one of the server components and not the piece with the Sentinel Control Center (SCC) actually running.

To tell the Sentinel components to work around this add the following Java Virtual Machine parameter to the process line for the DAS Query process throwing the error in $ESEC_HOME/config/configuration.xml:

-Djava.awt.headless=true

The line may end up looking like the following (new section in bold):
<process component="DAS" depends="UNIX Communication Server,Windows Communication Server" image="&quot;$(ESEC_JAVA_HOME)/java&quot; -server -Dsrv_name=DAS_Query -Xmx128m -Xms64m -XX:+UseParallelGC -Xss136k -Xrs -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=../log/DAS_Query.hprof -Duser.language=en  -Djava.net.preferIPv4Stack=true -Dfile.encoding=UTF8 -Desecurity.cache.directory=../data/das_query.cache -Desecurity.dataobjects.config.file=/xml/BaseMetaData.xml,/xml/WorkflowMetaData.xml -Djava.util.logging.config.file=../config/das_query_log.prop -Djava.security.auth.login.config=../config/auth.login -Djava.security.krb5.conf=../config/krb5.conf -Desecurity.execution.config.file=../config/execution.properties -Dcom.esecurity.configurationfile=../config/configuration.xml -Djava.awt.headless=true -jar ../lib/ccsbase.jar ..//config//das_query.xml" min_instances="1" name="DAS_Query" post_startup_delay="20" type="container" working_directory="$(ESEC_HOME)/data"/>

The same change may need to be made to the Collector Manager (CM) for a similar issue when browsing to find a file for a file-based event source.  The AWT class can be seen in an exception when the Collector Manager is started though most functionality will be present in these cases until the browse button is used in Event Source Management (ESM).

The log file has an entry similar to the following:
