JavaWeb项目打包部署之后,如果web-inf/lib下面有jar包增加/更新了,我需要重新编译吗?
还是不需要编译,直接就可以用增加/更新的jar包呢?

2个回答

编译是为了把jar包、java文件、html文件等进行汇总,顺便对java文件进行编译成class文件,如果lib目录下更新了jar包,原来的war包又不会自动把jar包放进去,所以,如果新放进去的jar包,还没java文件用到,那么可以不用重新编译,如果已经用到了,那就需要编译

如果更新的jar包在你做的东西里面有用到就要重新编译,反之不用

java web项目部署到Linux后访问WEB-INF/classes文件下一个文件的问题

java web项目部署到Linux服务器上,其中有一个模板下载的请求连接,模板文件就是放在src下面编译后放在classes文件夹下。现在问题是访问这个下载链接时,项目日志报异常了No such file or directory。是不是我这个java应用没有访问这个文件的权限呢?怎么才能让它能访问呢?

java 项目 导入成功后jsp页面报错处理方法

本人新导入一个maven项目可是jsp页面一直报错,我先按照网上的经验操作如下步骤:   在pom.xml配置文件中添加上javax.servlet的相关依赖:     <dependency>     <groupId>javax.servlet</groupId>     <artifactId>servlet-api</artifactId>     <version>2.5</version>     <scope>provided</scope>     </dependency>  依赖tomcat类库:     项目右击—>build path —> configure build path — >libraries — > add libraries —> Server Runtime — >选择一个服务器lib —> ok   此方法并没有解决jsp报错问题,最终经过搜索发现如下方法:     windows—>Preferences—>Validation—>把Show a confirmation dialog when performng manual validations 前边的√去掉—>Disable All —> apply —> ok   此方法最终解决问题 参考链接:http://blog.csdn.net/qq_24081681/article/details/66969452

在myeslicpe 发布问题和 serlvet 404错误问题

新手求教:第一个问题是myeslicpe10 配置好tomcat 服务器 新建一个javaweb项目然后发布会出现这个![图片说明](https://img-ask.csdn.net/upload/201605/24/1464103164_919712.png)![图片说明](https://img-ask.csdn.net/upload/201605/24/1464103181_105745.png)百度了一下说是什么jar包的问题,可是我是新建的什么也没有的WEB工程没导入过任何包,然后就算把最基本的包删了重新导入也不行,然后既然这样不行就只有手工移动,我在src里建立一个包里面有一个servlet叫Sc(当然里面啥也没写),然后web.XML是系统自动配好的![图片说明](https://img-ask.csdn.net/upload/201605/24/1464103533_141155.png)然后我把整个工程文件夹放在tomcat的webapps下,可以访问localhost:8080/gugu(项目名)/WebRoot/index.jsp 但是访问localhost:8080/gugu(项目名)/servlet/sc就会出现404错误,然后我又发现我的项目里web-inf里的lib什么也没有,我就从tomcat的lib里考来一个servlet-api.jar包,然后还是404错误,一直搞不定xml配置也没错包也有了为什么还是404 求大神解答。 PS:我还想知道为啥那个包没有自动导入,是因为没发布吗 ?

Java Web开发新手请教个问题(eclipse第三方jar的正确导入方式)

比如我导入第三方jar包, 我在JSP页面用了这个包,eclipse编译倒是通过。但浏览器弹出来就显示XXX cannot be resolved to a type. 我是这样导入的:右击项目,Build Path-->Libraries-->Add External JARS,还有我把该jar包也放在项目中的WEB-INF的Lib文件下了,还是没用。 凡是用到第三方包,eclipse编译都通过,浏览器跳出来的都是XXX cannot be resolved to a type. 只要不用到第三方包,都不会出问题,我确定Tomcat没问题的。 <%page import=""%>方面确定没问题的。 ![图片说明](https://img-ask.csdn.net/upload/201603/02/1456914023_89851.png) 以上我导入了mail.jar和activation.jar包,在JSP页面写道: Session mailSession = Session.getDefaultInstance(properties); 最后eclipse编译没报错,但是浏览器却如下该结果: ![图片说明](https://img-ask.csdn.net/upload/201603/02/1456914236_797075.png)

急!在线等。使用maven把项目打成war包,java文件没有被包含进去!!!!

希望大牛能帮我解答一下疑惑,小弟感激不尽。 项目介绍:自己搭的Spring Spring MVC MyBatis JavaWeb项目,JDK:1.8. 今天用maven打包项目,莫名其妙的java文件就打包不进去了, 没有修改过pom.xml文件,执行mvn clean install / mvn package / mvn compile 都打包成功,不报错,但是就是没有包含进java文件

myeclipse web项目出现红叉,不是jar包的原因。

[急救]为什么我部署了web工程,启动了tomcat,就是找不到我的页面

struts2+hibernate+spring 使用全注解, 当我部署了我的工程,启动tomcat,然后访问我的页面,显示的是404,郁闷死我了,开始的时候,web工程里面是META-INF、WEB-INF、index.jsp这几个东西,访问index.jsp的时候,显示的是404,但是当我把工程里面的WEB-INF和META-INF删除之后,只留下一个index.jsp页面,然后再访问index.jsp,可以访问了,我搞不清楚是什么原因,郁闷死我了,找了好久 启动tomcat的时候: [code="java"] 2011-3-31 17:31:24 org.apache.catalina.core.AprLifecycleListener init 信息: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: D:\Program Files\MyEclipse 6.5\bin;E:\java\J2EEServers\apache-tomcat-6\apache-tomcat-6.0.20\bin 2011-3-31 17:31:24 org.apache.coyote.http11.Http11Protocol init 信息: Initializing Coyote HTTP/1.1 on http-8080 2011-3-31 17:31:24 org.apache.catalina.startup.Catalina load 信息: Initialization processed in 846 ms 2011-3-31 17:31:24 org.apache.catalina.core.StandardService start 信息: Starting service Catalina 2011-3-31 17:31:24 org.apache.catalina.core.StandardEngine start 信息: Starting Servlet Engine: Apache Tomcat/6.0.20 2011-3-31 17:31:25 org.apache.catalina.core.ApplicationContext log 信息: ContextListener: contextInitialized() 2011-3-31 17:31:25 org.apache.catalina.core.ApplicationContext log 信息: SessionListener: contextInitialized() 2011-3-31 17:31:26 org.apache.catalina.util.ExtensionValidator validateManifestResources 信息: ExtensionValidator[][commons-attributes-compiler.jar]: Required extension "ant" not found. 2011-3-31 17:31:26 org.apache.catalina.util.ExtensionValidator validateManifestResources 信息: ExtensionValidator[][commons-attributes-compiler.jar]: Required extension "qdox" not found. 2011-3-31 17:31:26 org.apache.catalina.util.ExtensionValidator validateManifestResources 信息: ExtensionValidator[][commons-attributes-compiler.jar]: Required extension "commons-attributes-api" not found. 2011-3-31 17:31:26 org.apache.catalina.util.ExtensionValidator validateManifestResources 信息: ExtensionValidator[][commons-attributes-compiler.jar]: Required extension "javadoc" not found. 2011-3-31 17:31:26 org.apache.catalina.util.ExtensionValidator validateManifestResources 信息: ExtensionValidator[]: Failure to find 4 required extension(s). 2011-3-31 17:31:26 org.apache.catalina.core.StandardContext start 严重: Error getConfigured 2011-3-31 17:31:26 org.apache.catalina.core.StandardContext start 严重: Context [] startup failed due to previous errors 2011-3-31 17:31:26 org.apache.catalina.core.StandardContext stop 信息: Container org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/] has not been started 2011-3-31 17:31:26 org.apache.coyote.http11.Http11Protocol start 信息: Starting Coyote HTTP/1.1 on http-8080 2011-3-31 17:31:26 org.apache.jk.common.ChannelSocket init 信息: JK: ajp13 listening on /0.0.0.0:8009 2011-3-31 17:31:26 org.apache.jk.server.JkMain start 信息: Jk running ID=0 time=0/32 config=null 2011-3-31 17:31:26 org.apache.catalina.startup.Catalina start 信息: Server startup in 1574 ms [/code] 那几个严重的log:我百度了,然后照着搞了也没搞好 ,我就搞不懂为什么访问不了页面呢,难道和WEB-INF有关系吗?里面也只有lib和web.xml呀,哪位大侠知道的帮帮我吧...谢谢了
