转的，此文章验证有效 SSH2组合完成后，执行hibernate的HQL查询时，报错： 
java.lang.NoSuchMethodError: antlr.collections.AST.getLine()I 看来是antlr这个语法解析包出错 
因为Struts2.1.8.1自带的antlr-2.7.2.jar,比Hibernate3.3自带的antlr-2.7.6.jar的版本要低，故要在build path里删除前一个低版本的。 删除前myEclipse的界面如下图： 
 
解决方法：假设你的myEclipse安装在G：\ Genuitec目录下 
1）修改myEclipse的安装目录的配置文件： 
G:\Genuitec\MyEclipse 8.5 1\configuration\org.eclipse.osgi\bundles\105\1\.cp\preferences.ini 
去掉其中的MYECLIPSE_STRUTS2_DATA_HOME/2.1/core/antlr-2.7.2.jar;\ 
然后再删除antlr-2.7.2.jar: 有两处 
G:\Genuitec\MyEclipse 8.5 1\configuration\org.eclipse.osgi\bundles\105\1\.cp\data\2.1\data 
G:\Genuitec\MyEclipse 8.5 1\configuration\org.eclipse.osgi\bundles\105\1\.cp\data\2.1core 
2）然后会发现在重新发布程序后，又在程序的lib目录下出现，没有真正删除。 
继续查看myEclipse的安装目录：仔细寻找相关配置文件。 
在myEclipse下，查看struts2包的属性： 
melibrary.com.genuitec.eclipse.struts2.MYECLIPSE_STRUTS21_CORE 
这是一个myEclipse的变量，查看这个字符串是在哪个文件中定义的。 
G:\Genuitec\MyEclipse 8.5 1\configuration\org.eclipse.equinox.simpleconfigurator \bundles.info 
找到其中的与struts有关的项，定位到struts2，即看到这个包 
G:\Genuitec\Common\plugins\com.genuitec.eclipse.struts2_8.5.0.me201003121946.jar 
再查看它，知道有个配置文件“preferences.ini”，修改它，去掉相关antlr-2.7.2.jar信息，然后再去掉包中自带的antlr-2.7.2.jar。 删除后myEclipse的界面如下图： 
 所以，最后小结如下： 
把G:\Genuitec\Common\plugins\com.genuitec.eclipse.struts2_8.5.0.me201003121946.jar包中的配置修改，并去掉其中的antlr-2.7.2.jar即可。 myEclipse的目录分两大类，一类是工作目录，一类是系统目录，而上述的包就放在系统目录中。

原文地址:http://hi.baidu.com/ż����/blog/item/fdd78e4f7aeeafc4d0c86aba.html 我用的myeclipse8.6， 装在 D:\MyEclipse8.6\，，SSH组合完成后，执行hibernate的HQL查询时，报错：
java.lang.NoSuchMethodError: antlr.collections.AST.getLine()I看来是antlr这个语法解析包出错
因为Struts自带的antlr-2.7.2.jar,比Hibernate3.3自带的antlr-2.7.6.jar的版本要低，故要删除前一个低版本的，， struts1.3 和2.1都带有antlr-2.7.2.jar ,,,下面我要把它们都清除了，，由于myeclipse 添加的struts性能不是放在工程lib下的，而是myeclipse自带的，，所以删除比较麻烦，，我觉得最简单的做法应该是这样：D:\MyEclipse8.6\MyEclipse-8.6\configuration\org.eclipse.osgi\bundles 下搜索antlr-2.7.2.jar完成后能看到的，都删除掉，，(可能有些是在1.3下面的，有些是在2.1下面的)然后在 D:\MyEclipse8.6\Common\plugins   搜索 *struts*.jar   会发现，出来三个选中 一个文件，，打开方式选择压缩包，，我的winRAR的，，com.genuitec.eclipse.cross.easystruts.eclipse_8.6.0.me201007231647.jar 在lib下和data\1.3下要删除antlr-2.7.2.jar(这个是删除1.3里面的)而再打开 com.genuitec.eclipse.struts2_8.6.0.me201007292038.jar   data\2.1\core 下删除antlr-2.7.2.jar (这个是2.1里面的)好了，，这个就从struts1.3和2.1中移除了，，因为这两个jar是common目录下的，所以删除了后，再运行myeclipse后， myeclipse就不能再从这两个包中找antlr-2.7.2.jar 并加载了 myeclipse8.5也适用
