Re: [Bigdata-developers] read only mode for the jar file

[Douglas F. <dr...@gm...>]

Bryan,
  I am following this and the docs.  However, when I pull the web.xml alter
the lines for read only to:

 <context-param>
   <description>When true, the REST API will not permit mutation
operations.</description>
   <param-name>readOnly</param-name>
   <param-value>true</param-value>
  </context-param>

I run with:  java -server -Xmx4g -Djetty.overrideWebXml=./override.xml
 -jar blazegraph.jar

I get errors

WARN : NanoSparqlServer.java:517: Starting NSS
WARN : AbstractLifeCycle.java:212: FAILED
org.eclipse.jetty.servlet.ServletHandler@239963d8:

sorry to be pest, I feel like I'm missing something simple.
