Project Folder Structure
Let’s create some necessary folders:
| 1. src/main/java/com/itblogs/config/
2. src/main/java/com/itblogs/controller/ 3. src/main/java/com/itblogs/dao/ 4. src/main/java/com/itblogs/dao/impl/ 5. src/main/java/com/itblogs/model/ 6. src/main/java/com/itblogs/service/ 7. src/main/java/com/itblogs/service/impl/ 8. src/main/java/com/itblogs/utils/ 9. src/main/resources/ 10. src/main/resources/messages/ 11. src/main/webapp/resources/css/ 12. src/main/webapp/resources/js/ 13. src/main/webapp/resources/img/ 14. src/main/webapp/WEB-INF/jsp/ 15. src/main/webapp/WEB-INF/lib/ 16. src/test/java/ |

Folder Structure:
| Folder | Details |
| src/main/java/com/itblogs/config/ | Store Spring configuration files |
| src/main/java/com/itblogs/controller/ | Controller Java classes |
| src/main/java/com/itblogs/service/ | Service Manager Interface classes |
| src/main/java/com/itblogs/service/impl/ | Service Manager classes implementing the interface |
| src/main/java/com/itblogs/dao/ | DAO classes |
| src/main/java/com/itblogs/dao/impl/ | DAO classes implementing the interface |
| src/main/java/com/itblogs/model/ | Model classes |
| src/main/java/com/itblogs/utils/ | Store any utilities Java classes here |
| src/main/resources/ | Store log4j.properties file |
| src/main/resources/messages/ | Store message property files |
| src/main/webapp/resources/css/ | CSS files of the web page |
| src/main/webapp/resources/js/ | JS files (such as JQuery and AngularJS) of the web page |
| src/main/webapp/resources/img/ | Image files |
| src/main/webapp/WEB-INF/jsp/ | JSP files |
| src/main/webapp/WEB-INF/lib/ | Store necessary Jar libraries
Please note that you don’t need to copy the Jar files here. Maven will handle it, please see “do some checking for WEB-INF/lib” below. |
| src/test/java/ | Store unit test Java classes |
OK, let’s do some checking for WEB-INF/lib:
a. Check Deploy Path
Right-click the project => select “Properties” => click “Deployment Assembly”
Make sure “Maven Dependencies” is mapping to “WEB-INF/lib” Deploy Path
b. Check classpath.xml
Right-click classpath.xml, open with Text Editor, make sure it contains below settings:
<classpathentry kind=”con” path=”org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER”>
<attributes>
<attribute name=”maven.pomderived” value=”true”/>
<attribute name=”org.eclipse.jst.component.dependency” value=”/WEB-INF/lib“/>
</attributes>
</classpathentry>
c. Copy jstl-1.2.jar from Maven (C:\{your maven path}\.m2\repository\javax\servlet\jstl\1.2\jstl-1.2.jar) to WEB-INF/lib/
Why do we need to copy? “Deployment Assembly” should map the Maven dependencies to WEB-INF/lib . Yes, it has. But, under the pom.xml, we set jstl as <scope>provided</scope>. That’s mean you expect container providing the dependencies at runtime. So, jstl-1.2.jar need to copy to WEB-INF/lib/ .
