 解决办法

Tomcat解决办法：网上搜索了一下，在catalina.sh里加上“-Djava.awt.headless=true \”，问题解决（一共添加了8处，Tomcat版本7.0.59）。参照如下修改

exec "$_RUNJDB" "$LOGGING_CONFIG" $LOGGING_MANAGER $JAVA_OPTS $CATALINA_OPTS \
        -Djava.endorsed.dirs="$JAVA_ENDORSED_DIRS" -classpath "$CLASSPATH" \
        -sourcepath "$CATALINA_HOME"/../../java \
        -Djava.security.manager \
        -Djava.security.policy=="$CATALINA_BASE"/conf/catalina.policy \
        -Dcatalina.base="$CATALINA_BASE" \
        -Dcatalina.home="$CATALINA_HOME" \
        -Djava.io.tmpdir="$CATALINA_TMPDIR" \
        -Djava.awt.headless=true \
        org.apache.catalina.startup.Bootstrap "[e-mail]" start

camel解决办法：没找到要添加的配置文件。

最终解决办法：来电后由于ups已无法正常供电，还需要重启服务器，等服务器完全启动后，再启动应用服务（综合分析是由于服务器没有完全启动，Xserver服务未启动就启动Tomcat、camel服务导致的）
