Question

我试图第一次开始使用Jasperserver，而且你可能在这一点上想到它并没有很好地结束。

我做了什么：

安装Tomcat v7.0.32
安装Jasperreport v7.1.0

注意：

当我安装jasperreport服务器时，我选择使用外部源。我把它与tomcat联系起来了。
在jasperreport安装期间，我还安装了postgreSQL。
当我安装tomcat时，我选择使用不同的端口8000 - ＆gt; 9000。
我使用的是Windows 10

我在做什么：

盯着tomcat管理员（以管理员身份）。
在浏览器localhost中打开：9000 / manager / html

错误：

如果我尝试访问localhost：9000 / jasperserver：

因此我检查了日志文件，并且多个文件中存在错误：

我真的不知道该怎么做！我试过谷歌，但一切都很旧，与我得到的错误无关。希望你能帮助我！

Answer 1

看来，即使您已安装Tomcat指向的JRE 1.7，您的系统仍具有实际运行的JRE 1.8。另外，您没有安装JDK。编译Java类是必需的。

尝试以下操作：

从http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html下载Windows的JDK 1.8。您必须先接受许可协议。
运行安装程序。除了安装路径外，应该没有太多可供配置的选项。记住此路径供以后使用
安装程序完成后，搜索“环境变量”。在那里，寻找PATH变量和CLASSPATH。如果不存在，则可以通过添加新变量来创建它们。
编辑PATH变量，添加“; path \ in \ step \ 2 \ bin \”。万一您不记得了，通常是C:\Program Files\Java\jdk1.8.0_131\bin\。 PATH变量提供了javac，java等可执行文件的位置...
创建JAVA_HOME变量并将其设置为“ path / to / jdk”。应该像C:\Program Files\Java\jdk1.6.0_25
创建JRE_HOME变量并将其设置为“ path / to / jre”。它看起来应该像JRE_HOME=C:\Program Files\Java\jdk1.6.0_32\jre
创建CATALINA_HOME变量，并将其设置为已将Tomcat 4.1安装到的目录的路径。它应该看起来C:\Program Files\Apache\tomcat\bin\startup
创建CLASSPATH变量并将其设置为“ path \ common \ lib \ servlet-api.jar”。它看起来应该像C:\apache-tomcat-6.0.14\lib\servlet-api.jar。
通过在cmd上回显它们，检查它们是否已正确设置。只需在cmd中键入%PATH%，%JAVA_HOME%，%JRE_HOME%等。它们应产生与先前步骤中设置的值相同的值。
最后，通过键入javac并在cmd上按Enter，检查Java是否已正确安装。如果得到类似“用法：javac ....”的输出，则表明它已正确安装。
运行您的项目。

PATH是操作系统（Windows，Mac OS X，Linux）使用的环境变量，它将在其中寻找要运行的本机可执行程序。 Java本身未使用JAVA_HOME，JRE_HOME。 Apache Tomcat希望将这些环境变量之一设置为JDK或JRE的安装目录。 CLASSPATH被tomcat之类的第三方应用程序用来将CLASSPATH中设置的内容注入到您制作的每个Java应用程序中。CATALINA_HOME指出了tomcat的安装，这可能是启动时需要的。

由于您未设置变量，错误可能会出现
