java工程转化为web工程
??? Eclipse下新建java工程后，将工程手工改造为web工程：
?? ?修改工程目录下的.project文件
??? 普通工程下的该文件内容是：
<?xml version="1.0" encoding="UTF-8"?><projectDescription> <name>xxx</name> <comment></comment> <projects> </projects> <buildSpec> <buildCommand> <name>org.eclipse.jdt.core.javabuilder</name> <arguments> </arguments> </buildCommand> </buildSpec> <natures> <nature>org.eclipse.jdt.core.javanature</nature> </natures></projectDescription>
?
替换成下面
<?xml version="1.0" encoding="UTF-8"?><projectDescription> <name>Pro</name> <comment></comment> <projects> </projects> <buildSpec> <buildCommand> <name>com.genuitec.eclipse.j2eedt.core.WebClasspathBuilder</name> <arguments> </arguments> </buildCommand> <buildCommand> <name>org.eclipse.jdt.core.javabuilder</name> <arguments> </arguments> </buildCommand> <buildCommand> <name>com.genuitec.eclipse.j2eedt.core.J2EEProjectValidator</name> <arguments> </arguments> </buildCommand> <buildCommand> <name>com.genuitec.eclipse.j2eedt.core.DeploymentDescriptorValidator</name> <arguments> </arguments> </buildCommand> <buildCommand> <name>org.eclipse.wst.validation.validationbuilder</name> <arguments> </arguments> </buildCommand> </buildSpec> <natures> <nature>com.genuitec.eclipse.j2eedt.core.webnature</nature> <nature>org.eclipse.jdt.core.javanature</nature> </natures></projectDescription>
?
另外在.class文件中设置：
<?xml version="1.0" encoding="UTF-8"?><classpath> <classpathentry kind="src" path="src"/> ...... <classpathentry kind="output" path="WebRoot/WEB-INF/classes"/></classpath>
?
src和output中的path选择你对应的java工程路径名
