Java Web directory structure

transferred from: http://blog.csdn.net/javaloveiphone/article/details/7828894directory structure of source files and bytecode files for Javaweb projects

1. The source file directory structure of the new project:

|----MyProject

|----. settings (folder)

|----. classpath

|----. Project

|----. mymetadata

|----src

|----WebRoot

|----Other static files:HTML,CSS,JavaScript, images,jsp pages, etc.

|----index.jsp: The page can be placed directly under the root directory

|----Meta-inf

|----Web-inf

|----Classes root directory: storing bytecode files

|----lib directory: storing third-party class library files

|----Web. XML: Application Deployment description file must be directory

|----TLD File: Tag Library description file

The corresponding explanation:

1, 1,. Settings folder: A configuration file containing various plugins.

1,2,. Classpath: Defines the $CLASSPATH that the project uses at compile time , which is to configure the entire project running environment

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

<classpath>

<classpathentry kind= "src" path= "src"/>

<classpathentry kind= "Con" path= "Org.eclipse.jdt.launching.JRE_CONTAINER"/>

<classpathentry kind= "Lib" path= "Lib/dom4j-1.6.1.jar" >

<classpathentry kind= "Con" path= "Com.genuitec.eclipse.j2eedt.core.J2EE14_CONTAINER"/>

<classpathentry kind= "Output" path= "Webroot/web-inf/classes"/>

</classpath>

From the data we can easily see that the above describes the project's dependent files:

1. Location of the source file (kind= "src")

2. Operating system environment,JDK runtime container (kind= "con")

3. Specific location information of the project's library (kind= "Lib")

4. In each LIB's XML child node, there is additional configuration information about it (for example, the "Javadoc_location" I configured)

5. Output directory of the project bytecode file (kind= "output")

1,3,. MyMetadata: Describes the configuration information for the project in MyEclipse

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

<project-module

Type= "WEB" project type

Name= "MyProject" project name

id= Unique identification of the "myeclipse.1343985658390" project within the workspace

context-root= Root path of "/myproject" request

j2ee-spec= "1.4" java standard

Archive= "Myproject.war" > post-packaged war file

<attributes>

<attribute name= "Webrootdir" value= "WebRoot"/> Web ROOT name

</attributes>

</project-module>

1,4,. Project: Describe project information

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

<projectDescription>

2, the project bytecode file directory structure:

|----MyProject

|----Other static files:HTML,CSS,JavaScript, images,jsp pages, etc.

|----index.jsp: The page can be placed directly under the root directory

|----Meta-inf

|----Web-inf

|----Classes root directory: storing bytecode files

|----lib directory: storing third-party class library files

|----Web. XML: Application Deployment description file must be directory

|----TLD File: Tag Library description file

3. Summary:

With the explanation of the above two directory structures, when the project is compiled, the src and webroot file paths are not available, so when a file is loaded in the configuration file:

<param-value>/WEB-INF/struts-config.xml</param-value>

<param-value>resource/struts/struts-config.xml</param-value> (resource in source file src)
