    designed specifically for dynamic web applications. This customizable editor allows

    developers to make it possible for anyone to create, edit and maintain web content

    without the need for HTML knowledge or programming expertise.

AreaEdit is a formVista compatible fork of the rapidly developing Xinha project.

    It is the code that is generated by the formVista FVML <htmleditor> tag during rendering. Xinha itself is a fork of the original HTMLArea component created by Mihai Bazon and

    sponsored by Interactivetools. AreaEdit maintains the original HTMLArea (modified BSD)

    license and is free to use. While it is designed to work within formVista without modification, AreaEdit does not

    requre formVista. It is a fully functional editor component supporting a number of

    plugins and can as easily be used as a standalone editor component for any PHP web

    application. The primary difference between AreaEdit and Xinha is one of focus. The Xinha project

    aims to be a rapidly developing feature-filled editor with many plugins. By contrast, AreaEdit takes a slower minimalists approach. It aims first and foremost

    to be functional and maintainable. The feature set we are focusing on is targeted

    squarely at the serious non-technical business user. Business users don&apos;t care

    about the nuances of HTML <br> and <p> tags, they just want the editor to work as

    they would expect. If your audience is primarly composed to developers or those familar with HTML, you

    should take a look at Xinha. AreaEdit is known to work with MSIE 5.5 or later and any modern Gecko based

    browsers. (FireFox, Mozilla).

问题描述Q学?nbsp;Hibernate持久化技术时Q用hibernate-annotations-3.4.0.GA版本做实验，做好了程序和配置文g后，q行E序出现 java.lang.IllegalAccessError: tried to access field org.slf4j.impl.StaticLoggerBinder.SINGLETON from class org.slf4j.LoggerFactory错误?br />
问题原因Qjar文g版本冲突

c?nbsp;org.slf4j.impl.StaticLoggerBinder在slf4j-api 中是cȝ公有静态变?
public static final StaticLoggerBinder SINGLETON = new StaticLoggerBinder();
以上是在|络上找的答案，也有很多q的Q但是我遇到q个问题Ӟ使用的Hibernate?.6的，q种Ҏ不适合?br /> 后来我将 hibernate-jpa-2.0-api-1.0.0.Final.jar 包也加了q来之后Q程序就好了。具体原因还在纠l?img src="http://www.aygfsteel.com/Images/dot.gif" alt="" />.

而在slf4j-log4j12Qslf4j-nop.jar, slf4j-simple.jar, slf4j-log4j12.jar, slf4j-jdk14.jar or logback-classic.jar其中之一Q中是U有变量:
private static final StaticLoggerBinder SINGLETON = new StaticLoggerBinder();

解决ҎQ?/span>1.修改slf的源代码Q将q个变量有私有改为公有，再打包，问题可解冟?br />
    2.在类路径先将slf4j-api.jar 删除Q再导入同版本的slf4j-api-1.5.6.jar 和slf4j-log4j12-1.5.6.jar Q问题可解决?/span>
我遇到这个问题时用的是Hibernate3.6Q是hibernate-jpa-2.0-api-1.0.0.Final.jar包加q去才解决了的。相同问题的朋友试试?
