Access restriction:The type HttpServer is not accessible due to restriction on required library

博主在写Java Http服务端时遇到代码报错,提示因所需库的限制,某些类型不可访问。通过查找发现是缺少指定地址下的jar包,如D:\\Java|jdk1.6.0_45\\jre\\lib\\rt.jar和C:\\Program Files\\Java\\jdk1.6.0_02\\jre\\lib\\ext\\servlet-api.jar,将其拷贝到项目并引入即可解决。

今天在写Http服务端时,粘过来的代码,上面报这么个错误:

如下:

Access restriction:The type HttpServer is not accessible due to restriction on required library D:\Java|jdk1.6.0_45\jre\lib\rt.jar

通过网上查找原来就是缺错误指定地址下的那个jar包喽。。。。。

所以按照错误提示 D:\Java|jdk1.6.0_45\jre\lib\rt.jar找到这个jar包,然后拷到你的项目里面,再把jar包引入就好了。

如图:

网上找时,发现有些友友出现不同的问题,把他遇到的情况也说下:

Access restriction: The type HttpServlet is not accessible due to restriction on required library C:\Program Files\Java\jdk1.6.0_02\jre\lib\ext\servlet-api.jar

没错,他也是这种情况:

把C:\Program Files\Java\jdk1.6.0_02\jre\lib\ext\servlet-api.jar 下的jar包拷贝到项目的 lib下并引入就好了。

You are not authorized to view this page. By default the Host Manager is only accessible from a browser running on the same machine as Tomcat. If you wish to modify this restriction, you'll need to edit the Host Manager's context.xml file. If you have already configured the Host Manager application to allow access and you have used your browsers back button, used a saved book-mark or similar then you may have triggered the cross-site request forgery (CSRF) protection that has been enabled for the HTML interface of the Host Manager application. You will need to reset this protection by returning to the main Host Manager page. Once you return to this page, you will be able to continue using the Host Manager application's HTML interface normally. If you continue to see this access denied message, check that you have the necessary permissions to access this application. If you have not changed any configuration files, please examine the file conf/tomcat-users.xml in your installation. That file must contain the credentials to let you use this webapp. For example, to add the admin-gui role to a user named tomcat with a password of s3cret, add the following to the config file listed above. <role rolename="admin-gui"/> <user username="tomcat" password="s3cret" roles="admin-gui"/> Note that for Tomcat 7 onwards, the roles required to use the host manager application were changed from the single admin role to the following two roles. You will need to assign the role(s) required for the functionality you wish to access. admin-gui - allows access to the HTML GUI admin-script - allows access to the text interface The HTML interface is protected against CSRF but the text interface is not. To maintain the CSRF protection: Users with the admin-gui role should not be granted the admin-script role. If the text interface is accessed through a browser (e.g. for testing since this interface is intended for tools not humans) then the browser must be closed afterwards to terminate the session.
