[英]Ant, Tomcat Build Error: java.lang.NoClassDefFoundError: org/apache/tomcat/util/buf/B2CConverter
Tomcat Version: 7.0.20 Tomcat版本:7.0.20
I am attempting to work my way through the following Spring MVC tutorial: http://static.springsource.org/docs/Spring-MVC-step-by-step/part1.html 我正在尝试通过以下Spring MVC教程: http : //static.springsource.org/docs/Spring-MVC-step-by-step/part1.html
In this tutorial, an ant build script is setup to deploy to tomcat using the manager. 在本教程中,将使用管理器设置ant构建脚本以部署到tomcat。 However, I run into some problems when I try to run any of the tomcat tasks.
但是,当我尝试运行任何tomcat任务时,我遇到了一些问题。
First off, in the tutorial, they still use org.apache.catalina.ant.InstallTask
which is deprecated, so I changed to org.apache.catalina.ant.DeployTask
. 首先,在教程中,他们仍然使用不推荐使用的
org.apache.catalina.ant.InstallTask
,因此我更改为org.apache.catalina.ant.DeployTask
。
Now the problem is that when trying to run the Tomcat tasks I get: 现在的问题是,当我尝试运行Tomcat任务时,我得到:

So I Googled around a bit and found some information stating that tomcat-utils.jar
should be in the class path so I added that into the fileset with the catalina-ant.jar but apparently the org.apache.tomcat.util.buf.B2CConverter
class is not in there. 所以我用Google搜索了一下,发现一些信息表明
tomcat-utils.jar
应该在类路径中,所以我用catalina-ant.jar将其添加到文件集中,但显然是org.apache.tomcat.util.buf.B2CConverter
类不在那里。
So next I started probing the jars with jar -tf
to find out if any contained the class. 接下来我开始用
jar -tf
探测罐子,看看是否包含了这个类。 I found out that tomcat-coyote.jar
had the class. 我发现
tomcat-coyote.jar
有这个类。 Even with including this in the fileset, the problem is not resolved. 即使将其包含在文件集中,问题也无法解决。
Does anyone have any ideas? 有没有人有任何想法?
I got this working by changing the classpath to 通过将类路径更改为,我得到了这个工作
<path id="catalina-ant-classpath">
<!-- We need the Catalina jars for Tomcat -->
<!-- * for other app servers - check the docs -->
<fileset dir="${appserver.lib}">
<include name="catalina-ant.jar"/>
<include name="tomcat-coyote.jar"/>
<include name="tomcat-util.jar"/>
</fileset>
<fileset dir="${appserver.home}/bin">
<include name="tomcat-juli.jar"/>
</fileset>
</path>
Like Jason, I tried Aidan's answer and it did not work. 像Jason一样,我尝试了Aidan的答案而且没有用。 With TomCat 7 the manager interface has changed a little.
使用TomCat 7,管理器界面发生了一些变化。 Instead of using /manager/list in the URL you have to use /manager/text/list.
而不是在URL中使用/ manager / list,您必须使用/ manager / text / list。 So I changed the list task in build.xml to the following:
所以我将build.xml中的list任务更改为以下内容:
<target name="list" description="List Tomcat applications">
<list url="${tomcat.manager.url}/text"
username="${tomcat.manager.username}"
password="${tomcat.manager.password}"/>
</target>
I also had to add the "manager-script" role to my admin user so that it would have the proper privileges for this operation: 我还必须将“manager-script”角色添加到我的管理员用户,以便它具有此操作的适当权限:
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<user username="admin" password="admin" roles="manager-gui,manager-script"/>
I found the same error when following the same tutorial. 我在遵循相同的教程时发现了同样的错误。 I had to make 3 changes so that the targets run correctly.
我必须进行3次更改,以便目标正确运行。
First, change the build.xml "list" target to add the /text above mentioned: 首先,更改build.xml“list”目标以添加上面提到的/ text:
<target name="list" description="List Tomcat applications">
<list url="${tomcat.manager.url}/text"
username="${tomcat.manager.username}"
password="${tomcat.manager.password}"/>
</target>
Second, change the catalina ant classpath: 第二,改变catalina ant类路径:
<path id="catalina-ant-classpath">
<fileset dir="${appserver.home}/lib">
<include name="catalina-ant.jar"/>
<include name="tomcat-coyote.jar"/>
<include name="tomcat-util.jar"/>
</fileset>
<fileset dir="${appserver.home}/bin">
<include name="tomcat-juli.jar"/>
</fileset>
</path>
And finally, add this to the tomcat-users.xml file: 最后,将其添加到tomcat-users.xml文件中:
<role rolename="manager-script"/>
<user username="tomcat" password="s3cret" roles="manager-gui,tomcat,manager-script"/>
And then it worked for me =) 然后它对我有效=)
为了使所有ant命令工作,可以在build.properties文件中更改管理器url,而不是在build.xml文件中定义“list”目标时更改url。
tomcat.manager.url=http://localhost:8080/manager/text
This seemed to work for me (Tomcat 7.0.21, OS X): 这似乎对我有用(Tomcat 7.0.21,OS X):
<path id="catalina-ant-classpath">
<fileset dir="${tomcat_dir}/lib">
<include name="catalina-ant.jar"/>
<include name="tomcat-coyote.jar"/>
<include name="tomcat-util.jar"/>
</fileset>
<fileset dir="${tomcat_dir}/bin">
<include name="tomcat-juli.jar"/>
</fileset>
</path>
<taskdef name="deploy" classname="org.apache.catalina.ant.DeployTask" classpathref="catalina-ant-classpath"/>
<taskdef name="undeploy" classname="org.apache.catalina.ant.UndeployTask" classpathref="catalina-ant-classpath"/>
<taskdef name="list" classname="org.apache.catalina.ant.ListTask" classpathref="catalina-ant-classpath"/>
Also have a look at my Catalina-Ant for Tomcat 7 article here: 另请查看我的Catalina-Ant for Tomcat 7文章:
http://paulgrenyer.blogspot.co.uk/2011/11/catalina-ant-for-tomcat-7.html http://paulgrenyer.blogspot.co.uk/2011/11/catalina-ant-for-tomcat-7.html
what worked for me was adding the four jar files to the build path 对我有用的是将四个jar文件添加到构建路径
Run -> run configuration -> choose you program, select Classpath tab on the right, click User Entries, then add external 4 jars from the tomcat directory 运行 - >运行配置 - >选择程序,选择右侧的Classpath选项卡,单击User Entries,然后从tomcat目录添加外部4个jar
After this my build.xml runs like before 在此之后,我的build.xml像以前一样运行
None of the other answer work for me. 其他答案都不适合我。 Instead I copied TOMCAT_HOME/lib/catalina-ant.jar, TOMCAT_HOME/lib/tomcat-coyote.jar, TOMCAT_HOME/lib/tomcat-util.jar and TOMCAT_HOME/bin/tomcat-juli.jar to the ANT_HOME/lib directory.
相反,我将TOMCAT_HOME / lib / catalina-ant.jar,TOMCAT_HOME / lib / tomcat-coyote.jar,TOMCAT_HOME / lib / tomcat-util.jar和TOMCAT_HOME / bin / tomcat-juli.jar复制到ANT_HOME / lib目录中。
It seems like the classpathref doesn't include these files properly. 似乎classpathref没有正确包含这些文件。
I new to Spring or even first use to tomcat, i'm just trying add classpath to subsection tomcat task in build.xml (in every tomcat task) and i dont why, but its works. 我刚接触Spring,甚至第一次使用tomcat,我只是尝试在build.xml中添加classpath到tomcat任务(在每个tomcat任务中),我不知道为什么,但它的工作原理。
<taskdef name="deploy" classname="org.apache.catalina.ant.DeployTask">
<classpath>
<path location="${appserver.home}/lib/catalina-ant.jar"/>
<path location="${appserver.home}/lib/tomcat-coyote.jar"/>
<path location="${appserver.home}/lib/tomcat-util.jar"/>
<path location="${appserver.home}/bin/tomcat-juli.jar"/>
</classpath>
</taskdef>
执行上面的更改并运行“ant list”之后,我收到了错误,java.io.FileNotFoundException:.... / manager / text / list“。它是通过从其安装目录启动tomcat而不是使用eclipse启动来解决的启动tomcat后,首先在浏览器中尝试“localhost:8080”。这应该显示tomcats页面。然后尝试运行“ant list”。它可以解决上面的问题。
I would suggest a minor modification to the previous answers. 我建议对之前的答案稍加修改。
Configuring a user to have both manager-gui and manager-script roles is strongly discouraged in the Tomcat 7 documentation 1 . 在Tomcat 7文档1中强烈建议不要将用户配置为具有manager-gui和manager-script角色。 It can leave your site open to CSRF attacks.
它可以使您的网站对CSRF攻击开放。
Defining separate users with different passwords for each role would be safer: 为每个角色定义具有不同密码的单独用户将更安全:
<role rolename="manager-"/>
<role rolename="manager-script"/>
<user username="admin-gui" password="s3cret1" roles="manager-gui"/>
<user username="admin-script" password="s3cret2" roles="manager-script"/>
In general, you only need to memorize the user name and password for the GUI user, so it's no burden to have a safer configuration. 通常,您只需要记住GUI用户的用户名和密码,因此拥有更安全的配置不会有任何负担。
Three Things- 三件事-
If using Tomcat 7.x Change fileset for catalina-ant-classpath 如果使用Tomcat 7.x更改catalina-ant-classpath的文件集
<path id="catalina-ant-classpath"> <!-- We need the Catalina jars for Tomcat --> <!-- * for other app servers - check the docs --> <fileset dir="${appserver.lib}"> <include name="catalina-ant.jar"/> <include name="tomcat-coyote.jar"/> <include name="tomcat-util.jar"/> </fileset> <fileset dir="${appserver.home}/bin"> <include name="tomcat-juli.jar"/> </fileset>
change the user in tomcat-users.xml to give user permission as manager-script 更改tomcat-users.xml中的用户以将用户权限授予manager-script
http://localhost:8080/manager/text
http://localhost:8080/manager/text

Change tomcat.manager.url property to http://localhost:8080/manager/text
将tomcat.manager.url属性更改为
http://localhost:8080/manager/text
您只需tomcat_home/lib/
目录中的catalina-ant.jar
tomcat-coyote.jar
和tomcat-util.jar
tomcat_home/lib/
到ant_home/lib/
目录中
I'm not sure why is this happening, but here's a workaround: http://www.coderanch.com/t/553582/Tomcat/java-lang-NoClassDefFoundError-org-apache 我不确定为什么会这样,但这是一个解决方法: http : //www.coderanch.com/t/553582/Tomcat/java-lang-NoClassDefFoundError-org-apache
I'm looking for the solution, once I get it I will try not to forget to post it in here. 我正在寻找解决方案,一旦我得到它,我会尽量忘记在这里发布它。
I use opensuse. 我用opensuse。
I am on Mac OS X. This worked for me: 我在Mac OS X上。这对我有用:
