Exception in thread "main"

这是错误的结果显示,
我用cmd java -version 看版本是1.8的,然后配置了环境变量,也导入了comm.jar和jdbc.jar 为什么还是提示错误,弄了好久了,求大伙帮忙!谢谢了!是不是我环境变量配置错了?图片说明

检查一下,在哪里调用zigbee.Main类了,有zigbee.Main这个类吗?

这是我的Main.java

去你的tomcat里看看有没有这个类的.class文件没有的话手动编译一下

如果说你在cmd里面可以看到版本号信息就说明环境配置是没问题的

公司的系統點擊一個功能的時候報java.lang.OutOfMemoryError: PermGen space
在公司的系統中點擊了一個打印的功能,前臺是用flex,后臺是java,打印的時候是彈出來一個jsp頁面,中間夾了大量的計算。在本地測試沒事 可以彈出來jsp頁面,但是放在測試機上時候就會報如下異常,我在測試服務器的環境變量里設置了 变名:JAVA_OPTS 变量值:-Xms1024m -Xmx1024m 還是沒有作用,不知道應該怎么處理了。是程序的問題嗎? java.lang.OutOfMemoryError: PermGen space at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:620) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124) at java.net.URLClassLoader.defineClass(URLClassLoader.java:260) at java.net.URLClassLoader.access$000(URLClassLoader.java:56) at java.net.URLClassLoader$1.run(URLClassLoader.java:195) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at java.lang.ClassLoader.loadClass(ClassLoader.java:251) at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:319) at org.eclipse.jdt.internal.compiler.parser.Parser.consumeClassHeaderName1(Parser.java:2161) at org.eclipse.jdt.internal.compiler.parser.Parser.consumeRule(Parser.java:5103) at org.eclipse.jdt.internal.compiler.parser.Parser.parse(Parser.java:9020) at org.eclipse.jdt.internal.compiler.parser.Parser.parse(Parser.java:9251) at org.eclipse.jdt.internal.compiler.parser.Parser.parse(Parser.java:9208) at org.eclipse.jdt.internal.compiler.parser.Parser.dietParse(Parser.java:7864) at org.eclipse.jdt.internal.compiler.Compiler.internalBeginToCompile(Compiler.java:587) at org.eclipse.jdt.internal.compiler.Compiler.beginToCompile(Compiler.java:357) at org.eclipse.jdt.internal.compiler.Compiler.compile(Compiler.java:371) at org.apache.jasper.compiler.JDTCompiler.generateClass(JDTCompiler.java:413) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:317) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:295) at org.apache.jasper.compiler.Compiler.compile(Compiler.java:282) at org.apache.jasper.JspCompilationContext.compile(JspCompilationContext.java:586) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:317) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:342) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:267) at javax.servlet.http.HttpServlet.service(HttpServlet.java:717) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:233)

字节跳动视频编解码面经
三四月份投了字节跳动的实习(图形图像岗位),然后hr打电话过来问了一下会不会opengl,c++,shador,当时只会一点c++,其他两个都不会,也就直接被拒了。 七月初内推了字节跳动的提前批,因为内推没有具体的岗位,hr又打电话问要不要考虑一下图形图像岗,我说实习投过这个岗位不合适,不会opengl和shador,然后hr就说秋招更看重基础。我当时想着能进去就不错了,管他哪个岗呢,就同意了面试...
Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
程序员必须掌握的核心算法有哪些?
由于我之前一直强调数据结构以及算法学习的重要性,所以就有一些读者经常问我,数据结构与算法应该要学习到哪个程度呢?,说实话,这个问题我不知道要怎么回答你,主要取决于你想学习到哪些程度,不过针对这个问题,我稍微总结一下我学过的算法知识点,以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的,并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构,当然,我也会整理一些看过...

比特币原理详解
一、什么是比特币 比特币是一种电子货币,是一种基于密码学的货币,在2008年11月1日由中本聪发表比特币白皮书,文中提出了一种去中心化的电子记账系统,我们平时的电子现金是银行来记账,因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述,这一层面介绍的文章很多,本文主要从更深层的技术原理角度进行介绍。 二、问题引入 假设现有4个人...

程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发...

Python实例大全(基于Python3.7.4)
博客说明: 这是自己写的有关python语言的一篇综合博客。 只作为知识广度和编程技巧学习,不过于追究学习深度,点到即止、会用即可。 主要是基础语句,如三大控制语句(顺序、分支、循环),随机数的生成,数据类型的区分和使用; 也会涉及常用的算法和数据结构,以及面试题相关经验; 主体部分是针对python的数据挖掘和数据分析,主要先攻爬虫方向:正则表达式匹配,常用数据清洗办法,scrapy及其他爬虫框架,数据存储方式及其实现; 最后还会粗略涉及人工智能领域,玩转大数据与云计算、进行相关的预测和分析。
