How to implement JAAS?�?

Hi all,
I'm building a web application using JSP and Sevlet, and I want to design a login page where users enter their name and pass. I heared that if I want to design that page I need to implement JAAS (Java Authentication and Authorization Service) please help me to do that and give me code, links, or articles that talk about design login pages.
thanx,

Some examples to help you get started...

Configure Tomcat to use custom JAAS login module - add the following to context.xml in META-INF
<Context reloadable="true">
     
     <Realm className="org.apache.catalina.realm.JAASRealm" appName="MyApp" userClassNames="com.myapp.security.jaas.CustomUserPrincipal"
          roleClassNames="com.myapp.security.jaas.CustomRolePrincipal" debug="1"/>
     
     <WatchedResource>META-INF/context.xml</WatchedResource>
     <WatchedResource>WEB-INF/web.xml</WatchedResource>
</Context>
Create a file called jaas.config
MyApp
    com.myapp.security.jaas.CustomLoginModule required;
Specify the jaas.config file as a system property when you start you app server
-Djava.security.auth.login.config=="C:/Projects/MyApp/jaas.config"[b]Implement the CustomLoginModule, CustomUserPrincipal and CustomRolePrincipal as shown in the sun tutorials
These classes need to be deployed where your application server can find them when it starts up, i.e. outside of your WEB-INF/classes and WEB-INF/lib
You can implement the CustomLoginModule how you like, but if your application maintains it's own user database it may get a bit messy - I didn't like the idea of the app server interogating my application database and becoming responsible for the login logic (e.g. lock the account after 3 incorrect attempts etc). For this reason my CustomLoginModule (running in Tomcat) invokes a remote login method in my web app over RMI. The login method return a User object if successful which is added to the CustomUserPrincipal so it can be retrieved in the web-app.
Not the nicest of designs I admit. If anyone can suggest a better approach I'd be glad to hear it. I'm also not a JAAS expert. My app is just for testing out things I'm interested in, it's quite possible I may have misunderstood something along the way.

How to implement secure help in SharePoint 2010?

Hi,
We are having a sharepoint site running over HTTPS. When I click on help link given on top right side, I get a security warning saying that only secure content content can be displayed. This is probably due to the non secure content(http) used by microsoft

Can anyone please suggest how to implement microsoft help having secure content?
Please see screenshot below:

Yes office.microsoft.com URL works when I use https:// instead of http:// .
Can you please let me know in which file this help function is used?
Please provide me with an example if possible.

How to implement a help feature in iView Tray

How to implement a help feature in an iView Tray?

Hi Gregor,
Could the answer be connected to the class com.sapportals.portal.prt.component.SystemModes ?
I can't really see how this class is called, but it gives the error message you are talking about
The method doHelp for SP2 Patch3 is provided below
public void doHelp(IPortalComponentRequest aRequest, IPortalComponentResponse aResponse)
        IPortalComponentContext context = aRequest.getComponentContext(IPOMConstants.DEFAULT_MODE);
        IPortalComponentProfile profile = context.getProfile();

        if(helpName == null)

        String helpURL = profile.getProperty("com.sap.portal.iview.HelpURL");
        String isolationMode = profile.getProperty("com.sap.portal.reserved.iview.IsolationMode");
        if(context != null)
            if(helpName != null)
                String componentName = context.getComponentName();

                        HtmlIFrame frame = new HtmlIFrame();
                        frame.setStyle("width:100%; height: 100%;");
                        frame.setSrc(helpURL);

The doOnNodeReady method is also rather interesting. Perhaps another way to solve it?

        NodeMode nodeMode = request.getNode().getNodeMode();
        if(nodeMode == NodeMode.HELP_MODE)
            IPortalComponentContext context = request.getComponentContext(IPOMConstants.DEFAULT_MODE);
            IPortalComponentProfile profile = context.getProfile();
            String helpName = profile.getProperty("com.sap.portal.iview.HelpName");
            if(helpName == null)
                helpName = profile.getProperty("HelpName");
            String helpURL = profile.getProperty("com.sap.portal.iview.HelpURL");
            String isolationMode = profile.getProperty("com.sap.portal.reserved.iview.IsolationMode");
            if(context != null && helpName == null && helpURL != null && helpURL.length() > 0 && (isolationMode != null && !isolationMode.equals("URL") || isolationMode == null) && helpURL.startsWith("http://"))
                request.redirect(helpURL);

How to implement SEARCH HELP for input field in WDA

Hi All,
I am doing a tool for my team. in this tool there are 4 input fields to show different processes. I implemented the 4 input fields and also bind the respective tables to these fields successfully. Actually I want to filter the data between 2 fields . Means the data in the 2nd input field should be based on the 1st input field. Means when I'll select for example 'CHI' (code for CHINA) in the 1st input field the 2nd field meant for country name should show all country name with value 'CHINA'. But the problem is that all values related to each field are in different table with no foreign key relationship and also some combinations are in single table..
I have tried the import and export parameter method for search help but no luck till now.
Can anyone please suggest me how to implement this scenario..
Thanks in advance...
sekhar

Hi sekhar,
Your Requirement can be implemented by OVS(Object Value selector) This is the custom search help .So that you can define on what basis the value has to be fetched.
Look at the below link
http://wiki.sdn.sap.com/wiki/display/WDABAP/ABAPWDObjectValueSelector(OVS)
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/606288d6-04c6-2c10-b5ae-a240304c88ea?quicklink=index&overridelayout=true
You need to use the component WDR_OVS.
It has 3 phases
In phase 1
     You will fetch the value from input field to F4 help dialog box.
In phase 2
     You will generate the search results , in this phase look for the input value given in field 2 and accordingly generate search result for the field 3.
In phase 3
     The selected value will be returned to the original screen.

How to implement JAAS With Weblogic 10.3

I am working on a migration project. A project is to be migrated from JBOSS to Weblogic 10.3. JAAS has been used in JBOSS for security purpose.
Required classess like LoginModule, CallBackHandler are customized and put into a jar file. Next a Login page has been created with action=”j_security_check”, which is supposed to be called whenever protected resource has been requested. In web.xml Roles and Policies are defined. There is a jboss-web.xml in which roles are mentioned. In web.xml
There is a login-config.xml that has been put into Jboss server classpath. In this file, some sql queries are there.
In weblogic I am not able to understand that how to configure this login-config, how to map roles and policies. Exactly I am not able to find what are the steps needed to implement this JAAS in weblogic10.3. I also tried using the Read-Only SQL Authenticator Provider under security Realms but not sure how to use groups, because I have no Group related tables in my DB.
Kindly anyone share the knowledge.

Hi,
I also want to do the same thing. Did you get any solution for this problem. If yes then please share it with me. I am struggling with this.
Thanks,
Sanjay

How to implement Value Help for Product ID?

Hi,
I have a Z-Component where I want to use the value help of the Product ID. I found several components which use this value help for Products but I can't get it to work in my component properly.
Does anybody have a short tutorial how I need to proceed?
Thanks in advance.

There is a search component that can be used for this purpose.
This is one function out of several. I don't have the complete implementation at hand but this will give you the first idea.
CALL METHOD cl_crm_uiu_prod_tools_search=>eh_onclosepopup_return_product
   EXPORTING
      ir_search_popup = search_popup
   CHANGING
      cr_context_node = lv_target_node
      cv_index        = gv_tableindex.

How to implement JAAS authorization with the weblogic 8.1 server

i wrote a code for both the authentication as well as authorization using jaas using the config file and the policy file.
This code works fine stand alone for the authentication as well as authorization.
But when i runs this code inside the server (Weblogic 8.1), authorization deos not works according to my policy file. i have given the policy file path in the startWeblogicServer.cmd script. even i have tried to work with my policies in the java.policy file by giving its path in the java.security file. but this is also useless.
Now, i have doubt that either <b>jaas authorization doesn't work with the weblogic</b>(i am using 8.1) or there is some configuration setting is missing from my side.
Is there anybody who can help me to come out of this problem. Or tell me authorization alternative in the weblogic. I will really appreciate if anyone can help with the some example code.

Image Adjustments doesn't implement changes - help.

Hope someone can help me with this:
I am using Photoshop 11.0.1. I have two copies, one for myself and one for student workers in my office. For some reason, when we try to make an image adjustment -- such as changing levels or contrast -- we can see the preview of the change, but then when we click OK to implement the change, it jumps back to its original state and doesn't make the change.
Any ideas why? This is driving me kind of nuts.

I would try resetting the preferences by keyboard method or the manual way. I didn't see the operating system listed so you will have to scroll down to find the operating system if you do the manual way. Link:

Edit. windows 7 pref location is same as Vista.

Implementing F4 Help functionality of ABAP work bench on Adobe form

Hi ,
http://help.sap.com/saphelp_nw2004s/helpdata/en/42/c8a3ccc84e136ee10000000a1553f7/frameset.htm
Above link gives following description about Web Dynpro Form UI Element ValueHelpDropDownList
<b>ValueHelpDropDownList contains the script that is required for the link to the server in order to retain the elements of the list field from the back end at runtime. This Library object enables the end user to set up an input help request to the SAP server. This request always works in online mode, but not in offline mode. A server-side update of the input help is possible.</b>
Please explain me how ValueHelpDropDownList UI Element works .
Please correct my understanding -
We use a RFC adaptive model BAPI to retrive data from R/3 system and bind the variable to ValueHelpDropDownList UI Element . This means we get the data from backend in intialization of PDF form ( It means it is one time activity which will be used to extract data from R/3 system to display to end user ).
Is there any alternative by which we can get data from R/3 system ( some thing similar to F4 help in ABAP work bench ).
Please let me know if any one implemented this functionality .
Regards,
Nanda

Hi Ankit,
Thanks for a reply. Could you please explain the details? I am mapping a context attribute to the whole column and the value help button besides the field.
Thanks
