我们用Eclipse创建Maven结构的web项目的时候选择了Artifact Id为maven-artchetype-webapp,由于这个catalog比较老,用的servlet还是2.3的,而一般现在至少都是2.5,在Project Facets里面修改Dynamic web module为2.5的时候就会出现Cannot change version of project facet Dynamic web module to 2.5,如图:

其实在右边可以看到改到2.5需要的条件以及有冲突的facets,解决这个问题的步骤如下:

1.把Servlet改成2.5,打开项目的web.xml,改之前:

    <!DOCTYPE web-app PUBLIC  
     "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"  
     "http://java.sun.com/dtd/web-app_2_3.dtd" >  
      
    <web-app>  
      <display-name>Archetype Created Web Application</display-name>  
    </web-app>  

 

改后:

    <?xml version="1.0" encoding="UTF-8"?>  
    <web-app version="2.5"  
        xmlns="http://java.sun.com/xml/ns/javaee"  
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
        xsi:schemaLocation="http://java.sun.com/xml/ns/javaee  
        http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">  
          
      <display-name>Archetype Created Web Application</display-name>  
    </web-app>  

 


2.修改项目的设置,在Navigator下打开项目.settings目录下的org.eclipse.jdt.core.prefs

    eclipse.preferences.version=1  
    org.eclipse.jdt.core.compiler.codegen.inlineJsrBytecode=enabled  
    org.eclipse.jdt.core.compiler.codegen.targetPlatform=1.5  
    org.eclipse.jdt.core.compiler.compliance=1.5  
    org.eclipse.jdt.core.compiler.problem.assertIdentifier=error  
    org.eclipse.jdt.core.compiler.problem.enumIdentifier=error  
    org.eclipse.jdt.core.compiler.problem.forbiddenReference=warning  
    org.eclipse.jdt.core.compiler.source=1.5  

 


把1.5改成1.6

    eclipse.preferences.version=1  
    org.eclipse.jdt.core.compiler.codegen.inlineJsrBytecode=enabled  
    org.eclipse.jdt.core.compiler.codegen.targetPlatform=1.6  
    org.eclipse.jdt.core.compiler.compliance=1.6  
    org.eclipse.jdt.core.compiler.problem.assertIdentifier=error  
    org.eclipse.jdt.core.compiler.problem.enumIdentifier=error  
    org.eclipse.jdt.core.compiler.problem.forbiddenReference=warning  
    org.eclipse.jdt.core.compiler.source=1.6  

 


打开org.eclipse.wst.common.component

    <?xml version="1.0" encoding="UTF-8"?>  
    <project-modules id="moduleCoreId" project-version="1.5.0">  
        <wb-module deploy-name="test">  
            <wb-resource deploy-path="/" source-path="/target/m2e-wtp/web-resources"/>  
            <wb-resource deploy-path="/" source-path="/src/main/webapp" tag="defaultRootSource"/>  
            <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/java"/>  
            <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/resources"/>  
            <property name="context-root" value="test"/>  
            <property name="java-output-path" value="/test/target/classes"/>  
        </wb-module>  
    </project-modules>  


xml version="1.0" encoding="UTF-8"?>  

    <project-modules id="moduleCoreId" project-version="1.6.0">  
        <wb-module deploy-name="test">  
            <wb-resource deploy-path="/" source-path="/target/m2e-wtp/web-resources"/>  
            <wb-resource deploy-path="/" source-path="/src/main/webapp" tag="defaultRootSource"/>  
            <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/java"/>  
            <wb-resource deploy-path="/WEB-INF/classes" source-path="/src/main/resources"/>  
            <property name="context-root" value="test"/>  
            <property name="java-output-path" value="/test/target/classes"/>  
        </wb-module>  
    </project-modules>  

 


打开org.eclipse.wst.common.project.facet.core.xml

    <?xml version="1.0" encoding="UTF-8"?>  
    <faceted-project>  
      <fixed facet="wst.jsdt.web"/>  
      <installed facet="java" version="1.5"/>  
      <installed facet="jst.web" version="2.3"/>  
      <installed facet="wst.jsdt.web" version="1.0"/>  
    </faceted-project>  

 


把<installed facet="java" version="1.5"/>改成<installed facet="java" version="1.6"/>,把  <installed facet="jst.web" version="2.3"/>改成  <installed facet="jst.web" version="2.5"/>

    <?xml version="1.0" encoding="UTF-8"?>  
    <faceted-project>  
      <fixed facet="wst.jsdt.web"/>  
      <installed facet="java" version="1.6"/>  
      <installed facet="jst.web" version="2.5"/>  
      <installed facet="wst.jsdt.web" version="1.0"/>  
    </faceted-project>  

 


都改好之后在打开看看,已经把Dynamic web module改成了2.5

好了,大功搞成,这是一种解决办法,但是治标不治本,更高级的就是自定义catalog,然后安装到本地,再创建的时候啥都有了,比如把现在流行的s(struts2)sh,ssi,s(springmvc)sh 创建catalog,包括包结构,部分代码啥的都有,下次写吧。
