It has to be implemnted if we want to do something on the start up of the
container and shitdown of container. It is usually done for initializing
surf objects

Set the JAVA_OPTS in the startup.bat of alfresco , so that we can start alfresco in the cosnsole instead of service.

CURL Response codes
Monday, February 6, 2012
Calling the WebScript from command line and Java class
import org.apache.commons.httpclient.methods.GetMethod;
/**
*
*/
/**
* @author basanagowda.patil
*
*/
public class Test2 {
/**
* Main class of entry point
*
* @param args
*/
public static void main(final String[] args) {
System.out.println("Lucene Backup is been triggered");
final String url = "http://ecmdev.patil.com/alfresco/wcservice/patils/tags/all";
final HttpClient client = new HttpClient();
final GetMethod httpGet = new GetMethod(url);
try {
httpGet.addRequestHeader("CTUSER", "HFPBB101");
client.executeMethod(httpGet);
final String response = (httpGet.getResponseBodyAsString());
System.out.println(response);
System.out.println("StatusText:::"+ httpGet.getStatusText());
httpGet.releaseConnection();
} catch (final Exception e) {
e.printStackTrace();
}
}
}
You can call the webscripts from the CURL .
1. By passing the header
curl --header "CTUSER:HFPBB01" http://ecmdev.patil.com/alfresco/wcservice/patil/tags/all
2. By passing username and password
curl -uhfpbb101:8999 http://ecmdev.patil.com/alfresco/s/cmis
The first one is the preferred approach. Now we can write the webscript which triggers lucene backup and call that webscript as mentioned above.
There are other ways of backing the lucene indexes trigger
1. JMX
2.Command line

Maven important tutorial
Creating Maven Projects
- mvn archetype:create -DgroupId=com._3kbo -DartifactId=application (create a project for building a jar file )
- mvn archetype:create -DgroupId=com._3kbo -DartifactId=webapplication -DarchetypeArtifactId=maven-archetype-webapp (create a web app project for building a war file)
- mvn archetype:generate (Select the number of the desired archetype.)
Building, Testing, Packaging and Installing to the Repository
- mvn clean (cleans the project, i.e. delete the target directory)
- mvn compile (compiles the source code)
- mvn test (if required compiles the source code, then runs the unit tests)
- mvn package (compiles, tests then packages the jar or war file)
- mvn clean install (cleans the project, compiles, tests, packages and installs the jar or war file)
- mvn install (compiles, tests, packages and installs the jar or war file)
- mvn -o install (compiles, tests, packages and installs the jar or war file in offline mode)
- mvn -Dmaven.test.skip package (package without running the tests)
- mvn -Dmaven.test.skip clean install (clean and install without running tests)
- mvn -o test (test offline)
Unit Tests
- mvn test –Dtest=AspectTest (run a specific test)
- mvn test -Dtest=*ModelTest (run a subset of tests using regular expression. E.g. test all ModelTest classes)
Excluding log4j.properties from jar file
Move log4j.properties from src/main/resources to src/test/resources.
That way it gets picked up by the testResources for testing but excluded from the jar file.
Manually Install a file to the Repository
mvn install:install-file -DgroupId=com._3kbo -DartifactId=model -Dversion=1.0.0 -Dpackaging=jar -Dfile=new_file.jar
Set Java Build Version
Documentation
The mvn site command builds a useful dependency tree at target/site/dependencies.html.
- mvn site (generate documentation in the target/site directory)
- mvn javadoc:javadoc (generate javadoc in target/site/apidocs directory )
- mvn help:active-profiles (lists the profiles currently active)
- mvn help:effective-pom (displays the effective POM for the current build)
- mvn help:effective-settings (displays the calculated settings for the project, given any profile enhancement and the inheritance of the global settings into the user-level settings.)
- mvn help:describe (describes the attributes of a plugin)
For large projects mvn site can run out of memory. Use MAVEN_OPTS in the mvn or mvn.bat script to allocate additional memory, e.g:
MAVEN_OPTS=”-Xmx512m -Xms256m -XX:MaxPermSize=128m”

Sharepoint flow in Alfresco 3.4.5
The above bean declaration is using properties defined in the vti.properties which are speciic to site.
vti.share.siteSettings=/page/site/.../customise-site
vti.share.siteGroupMembership=/page/site/.../site-members
vti.share.userInformation=/page/user/.../profile
vti.share.documentLibrary=/page/site/.../documentlibrary
vti.share.documentDetails=/page/site/.../document-details
vti.share.calendar=/page/site/.../calendar
In the run time these values will be used by MS office.
alfresco-vti-3.4.5.jar is using the code required for the sharepoint communication.
AlfrescoDwsServiceHandler has the implementation to replace the node id urls
String uuid = req.getParameter("nodeId");
String uri = req.getRequestURI();
String redirectTo;
if (uuid != null)
{
// open site in browser
final NodeRef siteNodeRef = new NodeRef(StoreRef.STORE_REF_WORKSPACE_SPACESSTORE, uuid.toLowerCase());
redirectTo = pagesMap.get("siteInBrowser");
redirectTo = redirectTo.replace("...", siteNodeRef.getId());
}
Communication happens with MS office docs using WebService response.
here
It talks about what info is required for integration in the class DwsServiceHandler
/**
* Returns information about a document workspace site and the lists it contains
*
* @param document the site-based URL of a document in a document library in the document workspace site
* @param id an optional document globally unique identifier (GUID)
* @param minimal determines whether the output includes information about the schemas, lists, documents, links, and tasks lists of a document workspace site
* @return DwsMetadata information about a document workspace site and the lists it contains ({@link DwsMetadata})
*/
public DwsMetadata getDWSMetaData(String documentURL, String id, boolean minimal) throws Exception;
If we have to support sharepoint protocol then we should have details about tasks,links and document list but in the normal doc we will not have this information.
The server will be done using the bean
The logs are as below

The flow will be
Filter → Handler →Request Dispatcher → Action(VtiBinAction) → Method
Authentication itself is been checked using the siteservice in the Group AlfrescoUserGroupServiceHandler.
/**
* @see org.alfresco.module.vti.handler.UserGroupServiceHandler#isUserMember(java.lang.String, java.lang.String)
*/
public boolean isUserMember(String dwsUrl, String username)
{
// Normalize the user ID taking into account case sensitivity settings
String normalized = personService.getUserIdentifier(username);
if (normalized == null)
{
return false;
}
boolean isMember = siteService.isMember(dwsUrl, normalized);
if (!isMember && authorityService.isAdminAuthority(username))
{
// Admin is allowed to do things even on sites they're not
// a member of. So, pretend they are a member so they're allowed
isMember = true;
}
return isMember;
}
In the DefaultAuthenticationHandler class it checks whether user belongs to site or not
authenticateRequest() → which inturn checks for whether user belongs to site or not. All the requests will be going through the filter and filter calls authentication code. There it fails since the user is not belonging to any of the site.
Conclusion :
All the requests will be passing through the filter which checks whether user belongs to any of the site or not. If the user is not member of the site then user will be stopped from accssing the document.
VtiFilter checks with authenticationhandler.
user = authenticationHandler.authenticateRequest(this.context, httpRequest, httpResponse, getAlfrescoContext());
public SessionUser authenticateRequest(ServletContext context, HttpServletRequest request, HttpServletResponse response,
String alfrescoContext) throws IOException, ServletException
{
if (delegate.authenticateRequest(context, request, response))
{
HttpSession session = request.getSession(false);
if (session == null)
{
return null;
}
SessionUser user = (SessionUser) session.getAttribute(USER_SESSION_ATTRIBUTE);
if (user == null)
{
return null;
}
if(isSiteMember(request, alfrescoContext, user.getUserName()))
{
return user;
}
delegate.restartLoginChallenge(context, request, response);
}
return null;
}
It checks of the user belongs to site. If not it gives back null.

Creation of the workspace leads to the creation of the site internally.
AlfrescoDwsServiceHandler and AlfrescoCheckOutCheckInServiceHandler these 2 handlers are most important and to be analysed to enable the online edit.
