前几天发现tomcat提示 Could not initialize class sun.awt.X11GraphicsEnvironment 问题。以为不验证，就没太关注，今天发现，有同事提示了个bug，验证码刷不出来，查看日志，报了很多这个个错误。才意识到问题的严重。
网上找了找资料：共两种解决方案
1：http://love-love-l.blog.163.com/blog/static/21078304200908595214/
2：http://tcrct.iteye.com/blog/507953
文章摘抄
方案一
修改${TOMCAT_HOME}/bin/catalina.sh (windows修改catalina.bat) 里加上一句 “CATALINA_OPTS=-Djava.awt.headless=true
如图
方案二
修改${TOMCAT_HOME}/bin/catalina.sh (windows修改catalina.bat)
查到-Djava.io.tmpdir="$CATALINA_TMPDIR"这行，并在这一行下加入:
-Djava.awt.headless=true \
共有八处的。
修改好保存再重启即可，此时，如果是用远程登录来修改的话，有可能需要修改catalina.sh这个文件的权限，用在tomcat\bin目录下输入chmod 777 catalina.sh修改即可！

# Control Script for the CATALINA Server
#
# Environment Variable Prerequisites
#
# Do not set the variables in this script. Instead put them into a script
# setenv.sh in CATALINA_BASE/bin to keep your customizations separate.
#
# CATALINA_HOME May point at your Catalina "build" directory.
#
# CATALINA_BASE (Optional) Base directory for resolving dynamic portions
# of a Catalina installation. If not present, resolves to
# the same directory that CATALINA_HOME points to.
#
# CATALINA_OUT (Optional) Full path to a file where stdout and stderr
# will be redirected.
# Default is $CATALINA_BASE/logs/catalina.out
#
# CATALINA_OPTS (Optional) Java runtime options used when the "start",
# "run" or "debug" command is executed.
# Include here and not in JAVA_OPTS all options, that should
# only be used by Tomcat itself, not by the stop process,
# the version command etc.
# Examples are heap size, GC logging, JMX ports etc.
#
# CATALINA_TMPDIR (Optional) Directory path location of temporary directory
# the JVM should use (java.io.tmpdir). Defaults to
# $CATALINA_BASE/temp.
#
# JAVA_HOME Must point at your Java Development Kit installation.
# Required to run the with the "debug" argument.
#
# JRE_HOME Must point at your Java Runtime installation.
# Defaults to JAVA_HOME if empty. If JRE_HOME and JAVA_HOME
# are both set, JRE_HOME is used.
#
# JAVA_OPTS (Optional) Java runtime options used when any command
# is executed.
# Include here and not in CATALINA_OPTS all options, that
# should be used by Tomcat and also by the stop process,
# the version command etc.
# Most options should go into CATALINA_OPTS.
#
# JAVA_ENDORSED_DIRS (Optional) Lists of of colon separated directories
# containing some jars in order to allow replacement of APIs
# created outside of the JCP (i.e. DOM and SAX from W3C).
# It can also be used to update the XML parser implementation.
# Defaults to $CATALINA_HOME/endorsed.
#
# JPDA_TRANSPORT (Optional) JPDA transport used when the "jpda start"
# command is executed. The default is "dt_socket".
#
# JPDA_ADDRESS (Optional) Java runtime options used when the "jpda start"
# command is executed. The default is 8000.
#
# JPDA_SUSPEND (Optional) Java runtime options used when the "jpda start"
# command is executed. Specifies whether JVM should suspend
# execution immediately after startup. Default is "n".
#
# JPDA_OPTS (Optional) Java runtime options used when the "jpda start"
# command is executed. If used, JPDA_TRANSPORT, JPDA_ADDRESS,
# and JPDA_SUSPEND are ignored. Thus, all required jpda
# options MUST be specified. The default is:
#
# -agentlib:jdwp=transport=$JPDA_TRANSPORT,
# address=$JPDA_ADDRESS,server=y,suspend=$JPDA_SUSPEND
#
# CATALINA_PID (Optional) Path of the file which should contains the pid
# of the catalina startup java process, when start (fork) is
# used
#
# LOGGING_CONFIG (Optional) Override Tomcat's logging config file
# Example (all one line)
# LOGGING_CONFIG="-Djava.util.logging.config.file=$CATALINA_BASE/conf/logging.properties"
#
# LOGGING_MANAGER (Optional) Override Tomcat's logging manager
# Example (all one line)
# LOGGING_MANAGER="-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager"
