I am using the openCMIS library against a cmis 1.0 compliant server and I noticed that whenever I call getRepositories on the server (an alfresco v3.2 & v5.0 server) I only receive a list with one repository as opposed to what I was expecting, i.e. the list of roots on the server. How do I retrieve the list of repository roots using the opencmis library?
EDIT
I inappropriately phrased the question so I will explain better.
What I would like to do is to be able to get the actual repository root id(i.e. store_root in alfresco for instance) NOT the root folder id , such that I can leverage that against the api to retrieve it's direct children i.e. objects at the same hierarchical level as root folder (Company Home in alfresco)
Alfresco only has one repository, so what you are seeing is correct.
To understand how to get the root folder (which is Company Home), then how to get the root folder's children, see here.
worked fine for me test it :
first you have to create a session and connect it with this :
private static Session getSession(String serverUrl, String username, String password) {
SessionFactory sessionFactory = SessionFactoryImpl.newInstance();
Map<String, String> params = new HashMap<>();
params.put(SessionParameter.USER, username);
params.put(SessionParameter.PASSWORD, password);
params.put(SessionParameter.ATOMPUB_URL, serverUrl);
params.put(SessionParameter.BINDING_TYPE, BindingType.ATOMPUB.value());
List<Repository> repos = sessionFactory.getRepositories(params);
if (repos.isEmpty()) {
throw new RuntimeException("Server has no repositories!");
}
return repos.get(0).createSession();
}
after that only use this
Folder folder = session.getRootFolder();
hope that helped you

I have a query regarding BTDF SSO config setting. I am beginner with BizTalk.
I am looking for SSO storage where credentials are stored and retrieved from SSO. I have built-in app located at C:\Program Files (x86)\Deployment Framework for BizTalk 6.0\Framework\DeployToolsork\DeployTools
Could anyone tell me how to store and retrieve from existing SSO config like SSOSettingsEditor which is the default provided by BTDF.
Using BTDF, you can store your configurations as provided in SettingsFileGenerator.xml in BizTalk SSODB. BTDF automatically store your configuration if IncludeSSO property is set to true in btdfproj file.
If you have provided your credential details in SettingsFileGenerator.xml file then only you will find them in SSODB.
You should use SSOSettingsEditor to retrieve or make changes to the configurations. In SSOSettingsEditor, type in your application name and press enter.
Refer to link: BTDF IncludeSSO
BTDF provides a library for modifying SSO Settings that it uses. The method is uses is slightly different from the default Microsoft sample SSO client, so take care regarding which one you're using.
Per that link, the class provides these methods:
namespace SSOSettingsFileManager
{
public static class SSOSettingsManager
{
public static void WriteSetting(string affiliateApplication, string propertyName, string propertyValue);
}
}
It should be fairly straightforward to call that method once you've added a reference to the SSOSettingsFileReader.dll in whatever C# project you have generating your password or updating it, i.e.
string newPassword = GenerateMyPassword();
SSOSettingsFileManager.SSOSettingsManager.WriteSetting("MyApplicationName", "Password", newPassword;);
You could also look at the source of how he's doing it if you want to implement the method yourself.
How to write a .NET Web Service that takes email id as input and searches the Active Directory to see if that user exists and returns a flag. I have an userID and Password that is used to query AD. Please describe how to do this and what else do I need?
Using WCF, you can achieve this fairly easily.
Step 1 - define a service contract
This defines your operations that you want, including the parameters they might need. Not knowing what exactly you might need, I just guessed and came up with something like this:
using System.ServiceModel;
namespace SearchAD
{
[ServiceContract]
public interface ISearchADService
{
[OperationContract]
bool EMailAddressExists(string emailAddress);
}
}
Step 2 - implement the service class
This means adding the "meat" to the bone (the service contract) - this is where you actually do what you're trying to do:
using System;
using System.DirectoryServices.AccountManagement;
namespace SearchAD
{
public class SearchADService : ISearchADService
{
public bool EMailAddressExists(string emailAddress)
{
// establish the Active Directory domain context to search in
PrincipalContext ctx = new PrincipalContext(ContextType.Domain, "YOURDOMAIN", userName, password);
// define your "query-by-example" user to search for
UserPrincipal qbeUser = new UserPrincipal(ctx);
qbeUser.EmailAddress = emailAddress;
// instantiate the searcher to find that user
PrincipalSearcher findUserByMail = new PrincipalSearcher(qbeUser);
// search for the user - did we find one?
UserPrincipal userByEmail = findUserByMail.FindOne() as UserPrincipal;
return userByEmail != null;
}
}
}
Of course, in this setup - you'll need to get your domain name, the user name and the password (for querying Active Directory) from somewhere - a config file, constants in your service class - whatever works for you!
With this, you basically have your WCF service that takes an e-mail address and searches Active Directory for a user account matching that e-mail address. If found, true is returned - false otherwise.
Now, with your WCF service, you now only need to know how to host it (in IIS or self-hosting), and how to create clients for it to use the service - but that's just very basic WCF know-how, you shouldn't have any trouble finding the necessary infomrmation and tutorials, if you don't have that know-how already !
The mechanism used to search Active Directory is the System.DirectoryServices.AccountManagement namespace, which is part of .NET 3.5 and newer. Read all about it here:
Managing Directory Security Principals in the .NET Framework 3.5
MSDN docs on System.DirectoryServices.AccountManagement
I'm a bit confused with what is written in the documentation(s) for Freemarker and Restlet's freemarker extension.
Here's the situation: The restlet engine serves an HTML representation of a resource (e.g. www.mysite.com/{user}/updates). The resource returned for this URI is an HTML page containing all the updates, that is created with a freemarker template. This application is hosted on a Glassfish v3 server
Question(s):
The freemarker configuration should only be loaded once as per the freemarker documentation:
/* You should do this ONLY ONCE in the whole application life-cycle:Create and adjust the configuration */
Configuration cfg = new Configuration();
cfg.setDirectoryForTemplateLoading(
new File("/where/you/store/templates"));
cfg.setObjectWrapper(new DefaultObjectWrapper());
What is the best place to do this in a Java EE app? I am thinking of having it as context-param in web.xml and using a ServletContextListener - but I'm not sure how to go about doing that.
As per freemarker's documentation we could also add a freemarkerservlet and map .ftl url-patterns to it. But this is already mapped by a Restlet servlet (i.e., the url-pattern of "/"). So having another one for *.ftl doesn't make sense (or does it?)
So the question is basically about how best to integrate with the 'configuration' of Freemarker so that it happens only once and what is the 'entry-point' for that piece of code (who calls it). Has anyone successfully used Freemarker + restlet in a Java EE environment? Any ideas?
Thanks!
This was a tricky question - indeed. Required me to go through the implementation of the source files in org.restlet.ext.Freemarker package - Phew!
Here's how you can do it
If you need to create your OWN Configuration Object, set the 'templateLoader' to use and then have TemplateRepresentation 'work' on it for rendering:
Configuration cfg = new Configuration();
ContextTemplateLoader loader = new ContextTemplateLoader(getContext(),"war:///WEB-INF");
cfg.setTemplateLoader(loader);
TemplateRepresentation rep = null;
Mail mail = new Mail(); //The data object you wish to populate - example from Restlet itself
mail.setStatus("received");
mail.setSubject("Message to self");
mail.setContent("Doh!");
mail.setAccountRef(new Reference(getReference(), "..").getTargetRef()
.toString());
Map<String, Object> data = new HashMap<String, Object>();
data.put("status", mail.getStatus());
data.put("subject", mail.getSubject());
data.put("content", mail.getContent());
data.put("accountRef", mail.getAccountRef());
rep = new TemplateRepresentation("Mail.ftl", cfg, data, MediaType.TEXT_HTML);
return rep;
If you are happy with the default and wish to use a class loader based way of loading the templates
//Load the FreeMarker template
Representation mailFtl = new ClientResource(
LocalReference.createClapReference(getClass().getPackage())
+ "/Mail.ftl").get();
//Wraps the bean with a FreeMarker representation
return new TemplateRepresentation(mailFtl, mail, MediaType.TEXT_HTML);
If you want to initialize the Configuration Object once and set the template by calling the setServletContextForTemplateLoading(...) method on the configuration object. You could always do this in a ServletContextListener
public class Config implements ServletContextListener {
private static Configuration cfg = new Configuration();
#Override
public void contextInitialized(ServletContextEvent sce) {
ServletContext sc = sce.getServletContext();
cfg.setServletContextForTemplateLoading(sc, "/WEB-INF");
}
public static Configuration getFMConfig()
{
return cfg;
}
}
And then call the static getFMConfig() and pass it to TemplateRepresentation as in 1
Things to note:
If you do get a protocol not supported Exception it'll be in case 2. Implies that the ServerResource doesn't know what protocol to use to access the file - It'll be the CLAP protocol of Restlet. You may have to set up the init-params for RestletServlet in the web.xml file and have CLAP as one of the param-values
The TemplateRepresentation has quite a few constructors - if you DON'T pass in a configuration object during instantiation (using another overloaded constructor), it will create a new Configuration() for you. So you don't have to do any configuration set up as in 2 (This may strike you as obvious but I assumed that you WOULD still need to set a configuration or it would 'pick it up from somewhere')
If you DO wish to have your OWN configuration setup you MUST pass it to one of the constructors
Have a look at the "war:///" string in the constructor of ContextTemplateLoader in 1. this is important No where is it mentioned what this baseUri reference should be, not even in the docs. I tried for quite a while before figuring it out that it should be "war:///" followed by the folder name where the templates are stored.
For case 2 you'll probably have to store the templates in the same package as the class file from where this code is accessed. If you see carefully you'll notice a LocalReference parameter as an argument to ClientResource saying that the resource is supposed to be locally present and thus you need to use the custom CLAP protocol (classLoader Access Protocol)
Personal Frustration point - why isn't all this even clarified in the documentation or ANYWHERE :)
Hope it helps someone who stumbles upon this post! Phew!
How to do it?
I don't want to use this:
HttpContext.Current.Server.MapPath
Is there a similar function that I can call without requiring a httpcontext?
For example if a start a thread doing some stuff i cant use the httpcontext, but i still need to get the path of the app. And no i can't pass the context as an argument or read it from a shared var.
Use the HttpRuntime.AppDomainAppPath property.
There are several options:
HttpRuntime.AppDomainAppPath
WebApplication -> Web root folder
UnitTest -> ArgumentNullException
ConsoleApplication -> ArgumentNullException
AppDomain.CurrentDomain.BaseDirectory
WebApplication -> Web root folder
UnitTest -> ...\AppDir\bin\Debug
ConsoleApplication -> ...\AppDir\bin\Debug
HostingEnvironment.ApplicationPhysicalPath
WebApplication -> Web root folder
UnitTest -> null
ConsoleApplication -> null
I would recommend to use AppDomain.CurrentDomain.BaseDirectory, because it can be used in any type of project and it can be set up.
You can for example set UnitTest BaseDirectory to point your web root folder the AppDomain.CurrentDomain.BaseDirectory by command:
AppDomain.CurrentDomain.SetData("APPBASE", "path to your web root");
I have run across this question when looking for way to compute an URL (permalinks in the Web application) to provide in some e-mail notifications.
These were generated on another thread, so HttpContext was not available and I wanted to avoid putting URL related information in the queue table used to generate the e-mails.
The code:
public static String GetCurrentAppDomainBasePath(String prefix = "http://")
{
return String.Format("{0}{1}{2}",
prefix,
System.Net.Dns.GetHostEntry("").HostName,
System.Web.HttpRuntime.AppDomainAppVirtualPath
);
}
The function returns the full virtual path like: http://full-host-name/AppName. Of course, there are some limitations: hardcoded protocol (http, https etc.) and using hostname instead of domain name (fails if multiple domains are defined on a single machine).
I am writing an ASP.NET (C#) application to create users for my domain. It also has to create folders and shares on a separate file server. I have so far been able to accomplish my task using
System.IO.Directory.CreateDirectory to create the folders,
a ("WinNT://fileserver/lanmanserver") DirectoryEntry to create the shares.
Unfortunately, my ASP.NET application has to run with impersonation on to create the folder. I don't like that. I would like to know if there is a way to create a folder on the file server using a DirectoryEntry object since i can pass the needed credentials to its constructor. Or, alternatively, is there a way to pass credentials to Directory.CreateDirectory?
Thanks in advance.
Here is the current code, just in case
strPath = "\\myServer\D$\newDir";
Directory.CreateDirectory(strPath);
using (DirectoryEntry deFS = new DirectoryEntry("WinNT://myServer/lanmanserver"))
{
using (DirectoryEntry deSH = deFS.Children.Add("newDir$", "fileshare"))
{
deSH.Properties["path"].Value = "D:\\newDir";
deSH.Properties["description"].Value = "My Stackoverflow sample share";
deSH.CommitChanges();
}
}
I don't believe you should be using DirectoryObject for that purpose, it wasn't made for such an access. But here's a trick you could be using to make impersonation easier. Create an impersonator class, which would implement IDisposable, something like this:
public class Impersonator : IDisposable
{
public Impersonator(userid, password)
{
... LogonUserEx();
... DuplicateToken();
... Impersonate();
}
public void Dispose()
{
... RevertToSelf();
}
}
then you would be able to do this:
using(new Impersonator("myaccount", "password"))
{
... do stuff that requires impersonation
}
As far as I know you have two options: impersonate a user that has permissions to create the directory on the remote share or give the permissions to the default user that runs asp.net services.
What is wrong with that? You are accessing a non-default resource on your network and the default privileges dont allow you to do that. It's pretty much like a regular user account trying to write on a network share.
The DirectoryEntry class has a constructor which take username and password as input. Have you tried this?
