JAAS LoginException, error.jsp

When I throw a LoginException in my Custom Login Module that my Custom AuthenticationProvider
and my web.xml file contains
<login-config>
<auth-method>FORM</auth-method>
<form-login-config>
<form-login-page>/login.jsp</form-login-page>
<form-error-page>/error.jsp</form-error-page>
</form-login-config>
</login-config>
How do I get the error message displayed on the error.jsp file that weblogic authomatically
loads
I tried <% exception.getMessage() %> and I get an exception stating that exception
doesn't exist.
thanks for any help

After processing your servlet ,forward it to JSP page and set that exception in object from servlet and accces it in JSP Page and display it.
Example:
//Servlet
String errorMessage;
if error occurs set errorMessage to that error.
request.setAttribute("Message",errorMessage);
//JSP
Acces Message string from request Object and display it imn JSP page using
String errorMessage=request.getAttribute("Message");
This shud work in your case.

How to propogate the JAAS LoginException to JSP

Hi,
I have written a simple LoginModule to plug in to tomcat 5.0xx. Just wondering is there a way to propogate LoginExceptions to a Tomcat JSP page.
The current situation is when during authentication, if I I were to abort the process ( login() returns false ), a LoginException would be thrown, but the error is printed as a stack trace in tomcats' log file. If I modify the exception thrown to FailedLoginException, no stack trace would be printed at all.
Now, the question is how am I able to get the exception on my JSP page instead of printing it out in the log file?
thanks in advance,
Tuan

How to get the error raised in LoginModule into the error.jsp page?

Hi,
I would like to get the Exception message raised in a LoginModule and display it "friendly" into my error.jsp page.
How to do that?
Thanks.
Stephane

I have posted this question a few times. These forums are useless for all but the simplest of problems.
Here is what you can do, of course it is unsupported, and may or may not break with a future release - all I can say is that it works in 10.1.3
In your loginmodule login() method, add the JAZNContextCallback to your callbacks array, then after the callbacks are handled you can access the request in the following way:
HttpServletRequest request = (HttpServletRequest) ((JAZNContextCallback)callbacks[2]).getContextObject(JAZNContextCallback.HTTP_SERVLET_REQUEST, null);
You can then add the error message to the request and your jsp or whatever will be able to access it.
By the way, JAZNContextCallback is contained in the jazncore.jar file.

Deployment Error -- JSP Compilation Error: java.lang.OutOfMemoryError -- nu

When I deploy WAR files with the precompile jsp option, I receive the following error:
Deployment Error -- JSP Compilation Error: java.lang.OutOfMemoryError -- null
Is there a way for me to precompile my jsp's without using this process? Once this blows up, the admin server gets hosed. This is very frustrating. Any suggestions would be appreciated.
Regards,
Joshua

You need little more memory :-), use java param -mx512M.
You can adjust it in OC Server properties
AS > OC4J_home(demo) > Server Properties
section Multiple VM Configuration, Command Line Options
Java Options: -mx512M

Redirect to error.jsp

Hi,
I am getting Http 500 Internal server error from tomcat. I have follwing Jsp fragment, that is throwing this error.
<c:if test="${ empty userId}">
     <c:forEach var='thisCookie' items='${cookie}'>
     <c:if test='${thisCookie.key == "NWPUSERNAME"}'>
<c:set target='${SharedCookieBean}' property='val' value='${thisCookie.value.value}' />
          <c:if test='${SharedCookieBean.valid == "true"}'>
     <c:set target='${UserBean}' property='userId' value='${SharedCookieBean.username}' />
               <c:if test='${SharedCookieBean.fflag == "true"} || ${UserBean.userFlag == "true"}'>
               <c:redirect url="error.jsp?error=2" />
               </c:if>
     <c:set target='${UpdateUserAuthenticatedBean}' property='userId' value='${SharedCookieBean.username}' />
<c:set target='${SetSessionParamsBasedOnUserIdBean}' property='req' value='${pageContext.request}' />
<c:set target='${SetSessionParamsBasedOnUserIdBean}' property='userId' value='${SharedCookieBean.username}' />
</c:if>
</c:if>
</c:forEach>
</c:if>
This happend when I give a bogus userid say xdf which is NOT present in the database during the authentication. server sends error 500, which i like to suppress and rather redirect to error.jsp(My redirect attempt in above code is NOT working). It does not redirect to error.jsp. It shows errro 500 Internal server error in the browser.
any help in redirecting it correctly to error.jsp??
pp

My guess would be there is an exception happening in the database lookup code. If you set a generic errorPage for your jsp page, you should be able to redirect properly.
Where does this occur - when you set the SharedCookieBean value?
You might also try the <c:catch> tag. Put it around the bit of code creating the error.
eg...
<c:catch var="except">
    // the bit of code that creates the exception
   <c:set target='${SharedCookieBean}' property='val' value='${thisCookie.value.value}' />
</c:catch>
<c:if ${not empty except}">
An exception occured - <c:out value="${except.message}"/>
</c:if>Cheers,

How to redirect to error.jsp, if servlet encounters error ??

how do i redirect to error.jsp file , if there is some error in my servlet file.
can i user response.sendRedirect() in catch clause or i should use RequestDispatcher in catch clause ??

You can use either way to redirect to error.jsp. If you want to pass your Request, response from servelet to JSP, then better to go for RequestDispatcher.

Weblogic 10 jaas and login.jsp and web.xml/weblogic.xml security constaints

Hello,
I struggled through and got the examples.security.jaas.SampleCallbackHandler.java and examples.common.utils.ExampleUtils.java/ExampleConstants.java into eclipse where they compile. A bean I made can call SambleCallbackHandler like such:
mybean.logmein(username,password,url). I can then do a mybean.getStatus() or even a mybean.returnCode(). It does seem to correctly identlify that it is authenticating me (I see in stdout logs that it shows success or failures. The problem I have is I do not know how to apply this weblogic and web.xml/weblogic.xml so that if authentication works it redirects me to the page requiring the authentication. In web.xml I have the following set up:
<security-role>
     <role-name>Admins</role-name>
</security-role>
<login-config>
     <auth-method>FORM</auth-method>
     <realm-name>default</realm-name>
     <form-login-config>
          <form-login-page>/login.jsp</form-login-page>
          <form-error-page>/badlogin.html</form-error-page>
     </form-login-config>
</login-config>
<security-constraint>
     <web-resource-collection>
          <web-resource-name>empower</web-resource-name>
          <description>These pages are only accessible by authorized users.</description>
          <url-pattern>/admin/*</url-pattern>
          <http-method>GET</http-method>
          <http-method>POST</http-method>
     </web-resource-collection>
<auth-constraint>
<description>These are the roles who have access</description>
<role-name>Administrators</role-name>
</auth-constraint>
     <user-data-constraint>
     <description>This is how the user data must be transmitted</description>
     <transport-guarantee>NONE</transport-guarantee>
     </user-data-constraint>
</security-constraint>
My weblogic.xml has:
<?xml version="1.0" encoding="UTF-8"?>
<wls:weblogic-web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:wls="http://www.bea.com/ns/weblogic/90" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd http://www.bea.com/ns/weblogic/90 http://www.bea.com/ns/weblogic/90/weblogic-web-app.xsd">
<wls:security-role-assignment>
<wls:role-name>Admins</wls:role-name>
<wls:principal-name>Administrators</wls:principal-name>
<wls:principal-name>dashap</wls:principal-name>
</wls:security-role-assignment>
</wls:weblogic-web-app>
With this set up, if I try to go to a page in /admin folder in my application, it correctly pops up the login page. The jaas in the bean is doing a loginContext.login(), which I thought does authentication too, but it never goes back to the /admin page I was going to that needed the authentication. With jaas, can I not use the web.xml FORM security option? Do I Need to use j_security in the login.jsp's form's action= option and j_username and j_password for the input type names? How do I use j_username/j_password things if I am using jaas? I could just ignore using the web.xml security stuff and put something in the pages that need authentication, but it would be easier if I could use jaas with the security featurs without doing all that. Note that my code above is using a realm called default just because that was what was in the example I got from the web. Does that need to be something else?

Hi John,
I would like magic of course. However, in this case I want something special: my authentication provider uses special means and contents of headers, cookies and service from external identity management systems to determine the user's identity.
I do not want the application to present the login dialog! I want to derive the identity and the fact that the user is logged in from whatever the authentication provider returns in terms of Subject.
Ideally, the flow is something like:
- user accesses an unprotected resource - resource is shown, no interaction with authentication provider
- user presses a link or button that takes him/her to a protected resource
- the authentication provider is contacted to work with the identity asserter to establish the identity of the current user and create a subject object for this user
- the application can access the subject and principals
- ADF Security recognizes the identity and the roles (based on the principals) and coordinates access based on this.
the authentication method is client certificate. presumably this prompts WebLogic/OPS to use an identity asserter to work with custom headers and cookies ("... when you configure a web application to use CLIENT-CERT authentication. In this case, WebLogic can perform identity assertion based on values from request headers and cookies. If the header name or cookie name matches the active token type for the provider, the value is passed to the provider."). No login form should be presented to the user, as all information required to perform the authentication is already available.
I am trying to understand what I must do to have the ADF application adopt the subject set by the authentication provider - if anything?!
If you more ideas to share - I would love to hear them.
best regards,
Lucas

Jaas login in uix, like the jaas login in jsp

I read the note on jaas with jsp / vpd
but this is not working on a uix application
is there a easy way to have jaas login with
uix

I am very interested in the solution to this also! Is there a solution? I can't imagine nobody else has run up against this because prompting for user/password via a dialog is one of the first things one would do.

Use the following code which will help you

con=DriverManager.getConnection("jdbc:oracle:thin:@hostname:port:SID",username,password);
continue with rest of the code.
Make sure classes12.jar or classes12.zip must be in classpath.

Sidharth ,

I would suggest you change your hostname "sid-87f00f29add", and check then. You can either change it and start the installation all over again OR follow the steps outlined in the following notes to do that.

Which JDK should be installed ?
Can somebody tell what exactly should be done for JSP Timing Out. I mean there should be something for that.. So many people have got the issue. Today night after work I am going to sit and diagnose the issue.
If anybody can give any pointers/directions as to how this is to be diagnosed. That would be of immense help.
