Web application suggestion

inspiron82

Hi,
I hope that this is the right section of the forum, in case feel free to move my post in the right one.

I have to make a web application that just have two jsp. They must be like original login.jsp and browse.jsp. I don't need need any other Alfresco's features.
I just need to login, see documents that my user can see and download them, logout, and audit login and and download(if possible).

Which is the best way?

I hope you can help me.

Thanks.

can u help me please?
It's important. Can u just tell em which API i have to use?
thanks

I think that you can use the same way used in Share UI, but now there isn't any documentation about it, but it is based on Alfresco Webscripts.
So you must unpacking share.war application and you can see how Alfresco has used Webscripts to implements all the features you need in Share.

Hope this helps.

Can u be more specific and tell what I have to look for?

The problem is that i need to have an alfresco's instance with default layout, plus an addtional login.jsp and browse.jsp with a custom layout. The problem is that to have this custom layout i have to modify alfresco-web-client.jar. So i have to use default alfresco-web-client.jar for the default layout, and the modified
alfresco-web-client.jar for the two jsp with custom layout. Is there a way to tell the default jsp to use the default alfresco-web-client.jar and the two jsp with custom layout to use the modified alfresco-web-client.jar? I have to use ONE instance of alfresco. So i must have all the two alfresco-web-client.jar in the lib folder.

Any suggestion would be appreciated as i have to complete a project ASAP.
thanks a lot.

You can't customize Alfresco Web Client (JSF Client) in that way, you need to use JSF to extend this application correctly.
If you want to extend JSF Client you must extend Alfresco, you could not modify Alfresco directly!

Here some informations:

Hope this helps.

thank you.
Another question.
Is there some API that let me browse folder and files, and let me download them?

openpj

Yes.
You can use Webscripts API with your own HTTP API or you can use some Webscript provided in Alfresco:
http://wiki.alfresco.com/wiki/Web_Scripts

You can use Web Services API (Java stub provided by Alfresco as a JAR library):
http://wiki.alfresco.com/wiki/Alfresco_Content_Management_Web_Services

You can use CMIS API:
http://wiki.alfresco.com/wiki/CMIS

You can use also JCR.

Hope this helps.

inspiron82

thanks a lot.
Can u please tell me which is the easiest way?
And can u eventually post some example code to browse folders and files?
thanks a lot.

Hi

I'm actually trying to do the same thing.

Would much appreciate if someone can give us more detail.

Thanks

Web Services API
If you need to implement a SOA service with Alfresco and you need to orchestrate many operations with repository with a unique call you can use Web Services API.
Web Services API allow to create a list of repository calls by operation type, all the operations are based on Content Manipulation Language (CML) provided by Alfresco.
Web Service Client can be used as a library in your Java project and you can invoke methods to call the repository.

WebScript API
Alfresco provide many WebScript deployed in with many features that you can call with an HTTP call.
WebScript allows you to invoke or create your own HTTP API.
To call an Alfresco WebScript you need only to make an HTTP call to Alfresco WebScript url, WebScript allow you to manage repository with HTTP methods (POST,GET,PUT,DELETE) as a REST API.
This is very easy to use but you must be sure that one of the WebScript actually provided by Alfresco it is what you need, otherwise you need to create your own webscript.
If you need to create your own WebScript you can implement it using JavaScript API (server side) provided by Alfresco or using Java directly.
To browse all the webscript actually provided by Alfresco:
http://localhost:8080/alfresco/service/

JCR API
This API is dedicated only for JEE projects and it is compliant to JCR Specs.
For me is not easy to use JCR

CMIS API
CMIS is the latest specs dedicated to interoperability of repositories, using it you can create client implementations that works with all the vendors that implement CMIS.
There are two bindings of this interface: Web Services and REST.
Actually Alfresco provides the most updated implementation of this specs but CMIS is now at 0.6 so I think that only for the end of the year we could create stable interfaces for production environment.

Hope this helps.

Ok,
I got the problem.
I have to implement a web application that let me make the login(and it's not a problem) and let me show to the final user (in a jsp) all the files in a specified alfresco's folder AND IN ALL OF ITS SUBFOLDER.
For example, if i have a folders' structure like this:

Folder1
       |
       |——–Folder2
       |              |
       |              |—–Folder3
       |
       |——–Folder4
       |                |
       |                |—–Folder5
       |                              |
       |                              |———Folder6
       |
       |——–Folder7

if I click on the link corresponding to the Folder1, I have to make a query to alfresco and list all the file contained in Folder1, Folder2, Folder3, Folder4, Folder5, Folder6, Folder7.

I think that I have to use Web Services and WebScript.
Can u please tell me which methods I have to use and which the right logic to make the trick?

Thanks a lot.

Hi,

For getting the files contained in the folder, you'll probably need to create your own webscript that "searches" for the files contained. What you need to do is get the NodeRef ID of the folders and pass it in to the webscript (the one you'll make) and in that webscript you write use something like search.luceneSearch. You can then pass the results via freemarker back to your customed UI side.

Question:
Can you tell me how does your Login work? Were you able to call Alfresco webscripts after logging in (without having to log in again, meaning the ticket remains)?

Thanks

For the login, for the moment, I just used the method start session.Isn't it enough?
I'm sorry but I can't believe that doesn't exist an API's method that retrieves files contained in a certain folder.
Is it possible to write a web script that returns the list of files that THE USER CAN SEE according to alfresco's roles?
And when I have this list, how can i make a list of link (in html) to download these files?

Can u give me an example code to retrieve Noderef Id of the above example starting from the path of Folder1?

Sorry for the questions but the API's documentation i found is poor.

Thanks

hyperation

Hi,

For start session, do you mean in Java code or some kind of Javascript? Can you tell me more about how your login is structured (classes, webpages,etc)?

As for getting the folder items, check out the Opsoro framework.

http://forge.alfresco.com/plugins/scmsvn/viewcvs.php/opsoro/trunk/source/web/webScripts/opsoro/?root=opsoro

Look at documents.get.* webscript.

Thanks

openpj

Alfresco WebScript use Foundation Services API and then all the contents that users see are profiled correctly according to Alfresco permission and roles.

You can take a look at Folder Webscript, this is a sample webscript that you can use to create your own webscript:

http://localhost:8080/alfresco/service/sample/folder/Company%20Home‍

This webscript is deployed here (from JSF Client):
/Company Home/Data Dictionary/Webscripts/org/alfresco/sample

If you want to get a content you can use one of these urls that are based in an unique webscript:

Content Retrieval (getContent)
GET /alfresco/service/api/node/content{property}/{store_type}/{store_id}/{id}?a={attach?}
GET /alfresco/service/api/path/content{property}/{store_type}/{store_id}/{id}?a={attach?}
GET /alfresco/service/api/avmpath/content{property}/{store_id}/{id}?a={attach?}
GET /alfresco/service/api/node/{store_type}/{store_id}/{id}/content{property}?a={attach?}
GET /alfresco/service/api/path/{store_type}/{store_id}/{id}/content{property}?a={attach?}‍‍‍‍‍‍

Hope this helps.

Now, I can i search a node symply by the path.
For example, I know that the folderZ has this path:

company_home/folderX/folderY/folderZ
‍‍‍

which lines of code i have to write to have a reference to the folderZ?

thanks

inspiron82

The problem is that i didn't found some good documentation and so i didn't understand the general logic of web services.

I make a connection to the repository, and then?

Is there some good documentation that will let me understand tecniques to make operations on the repository?

thanks
