如何处理jasperReport在linux系统下x11问题？

如何处理jasperReport在linux系统下x11问题？

前段时间利用jsp,tomcat和jasperReport工具,开发一个报表管理web系统,在windows下测试正常,但在linux下部署却遇到了x11的问题,大概就是如下的错误代码:

java.lang.InternalError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.

经过多方查找资料,最终发现了网友们提供的几个解决办法,

1.对于 Java 1.4以上，启动java时加上 -Djava.awt.headless=true 的参数。对于 Java 1.4 以前，下载 xvfb 或者其他的虚拟 x-window 软件，再在 Java 运行环境里的 DISPLAY 作相应改变。

2.对于 Resin，具体的修改办法是，修改 httpd.sh 文件，把其中的 args= 行修改为 args=- Djava.awt.headless=true。

3.对于tomcat, 在catalina.sh中插入 -Djava.awt.headless=true

具体位置如下所示,

# Environment Variable Prequisites
#
# 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_OPTS (Optional) Java runtime options used when the "start",
# "stop", or "run" command is executed.
#
# 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.
#
# JAVA_OPTS (Optional) Java runtime options used when the "start",
# "stop", or "run" command is executed.
#
# 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.
#
# JSSE_HOME (Optional) May point at your Java Secure Sockets Extension
# (JSSE) installation, whose JAR files will be added to the
# system class path used to start Tomcat.
#
# CATALINA_PID (Optional) Path of the file which should contains the pid
# of catalina startup java process, when start (fork) is used

以上三个方法,我只验证了第三种,确实可行.
