Urgent! Multiple JAAS login call in one JVM

I am using Weblogic 6.0+sp1 and JAAS login. My use case requires
multiple connection to the weblogic server with different user
credential for each connection.
Is it possible to have JAAS login called multiple times in one JVM, each
call has different user credential? I saw behavior like this: the first
JAAS login call after start a JVM always works by authenticating the
user, however, the subsequent call just ignore the new user and ignore
the authentication process. Any document I can reference or this is a
bug?
Any help will be highly appreciated!

In theory it must work with different logins at the same time. As I know
it works with ACL. You may need to verify how the ACL is setup if ACL is
used.

Multiple (parallel) RFC Calls through one connection?

Hi SAP gurus,
Is there a possibility for parallel RFC calls through one open connection via one SAP system user?
As I know when calling RFCs it opens a new session and the dialog users have only 6 sessions permitted.
Do you know any possible solution for this?
Thanks a lot in advance

Is this question about the SAP StreamWork APIs. I think you have posted to the wrong forum.

How to create Jaas Login module !! Urgent

Hi developers
I want to make some changes in logon messages. Right now we are getting only error user authentication failed on the portal even if user is locked or some other reason is there for failed authentiaction. I want proper message should be displaying based on user input. For it I hope its good to create Jaas logon module so that i can modify it accordingly .
kindly if any one can give me way out , its urgent.
how to create it step by step. it would be highly appriciable.
any inputs are appriciated .
Thanks in advance

Urgent: JAAS Login Module Deployment Problem

Hi,
I have developed a JAAS Login module for the portal (EP6 SP9 sneak preview) and i am getting the following error:
GroupAssignmentLoginModuleLibrary does not exist in LoadContextWrapper.modifyName.
com.sap.engine.services.security.exceptions.BaseSecurityException: Can not load a login Module
The next line is a ClassNotFoundException for the Login Module and the class found in negative cache.
Please let me know if you know the solution to this problem.
It is an urgent issue and a solution will be suitably rewarded.

Hi Diego,
Scenario 1: SAP EP to SAP Backend Integration
      In this scenario the most commonly used strategy
      is SAP logon tickets. As far as I know this is the
      best and simple way to implement SSO.
Scenario 2: SAP EP to Non SAP systems.
      In this scenario various mechanisms can be used.
      It depends on the application you are integrating
      with. SAP does deliver SSO soultions with Lotus
      Notes and Outlook etc. If supported probably it is
      simple to use the SAP solution [Reliability and
      Support].
Scenario 3: Enterprise Uses third party authetication
      Software.
      For the authntication if the company chooses to use
      some third party product like SiteMinder etc, then
      you can simply use this solution for SAP EP authe-
      tication, and also all your other enterprise
      applications based on the product support. But SAP
      EP to other SAP systems be best integrated with SAP
      logon tickets.
Scenario 4: SSO using homegrown authetication or some
      third party JAAS module.
      If you have significant applications that are home
      grown that uses some custom authentication mecha-
      nism (Example: Authentication based on ID and
      Password stored in company database ) you can write
      a JAAS module extention to authenticate using that
      database. In other words JAAS is flexible and
      for using external authentication mechanisms.
There are several mechanisms available that all depends
on your internal applications/security mechanism/integration etc.
Here is the link to one of the good articles on SDN about the SAP supported SSO mechanisms.
https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/library/uuid/58094632-0301-0010-a391-fc0de26f010e
Hope this information is useful.

How do I run multiple java apps in one JVM to reduce memory use?

Hi all,
I saw an article either on the web or in a magazine not too long ago about how to "detect" if the app is already running, and if so, it hands off the new instance to the already running JVM, which then creates a thread to run the Java app in. As it turns out, my app will be used in an ASP environment, through Citrix. We may have as many as 50 to 100 users running the same app, each with their own unique user ID, but all using the same one server to run it on. Each instance eats up 25MB of memory right now. So the question is if anybody knows of a URL or an app like this that can handle the process of running the same (or even different Java) apps in one JVM as separate threads, instead of requring several instances of the JVM to run? I know this article presented a fully working example, and I believe I know enough to do it but I wanted ot use the article as a reference to make sure it is done right. I know that each app basically would use the same one "launcher" program that would on first launch "listen" to a port, as well as send a message through the port to see if an existing launcher was running. If it does, it hands off the Java app to be run to the existing luancher application and shuts down the 2nd launching app. By using this method, the JVM eats up its normal memory, but each Java app only consumes its necessary memory as well and doesn't use up more JVM instance memory.
Thanks.

URGENT: JAAS Login Module in Clustered Environment

Hello all,
I've created out own JAAS Login Module which works perfectly on a single-node environment... i dropped the jar in /server/additional-lib and modified library.txt and authschemes.xml as needed.
Now that we need to deploy it in a clustered node environment, we added the jar file into the additional-lib folders of all the nodes and edited all the library.txt files of all nodes.
UME cant seem to find our jar file anymore and we get the "missing handler" error when we try to login.
Any ideas?
Thanks,
Yves

If you are using SAP J2EE PL21+ there is a separate node called state controller (you have dispatcher, application nodes and state controller nodes). Basically the state controller makes sure all application nodes (server nodes) are synchronized
You can find the dispatcher under cluster\dispatcher, servers under cluster\server and state under cluster\state .
If you are using SAP J2EE PL20 or less this does not apply.

Can I Call method on one JVM from another through a dll?

Let me explain.
I have this java jar file that I can only have one instance of running at any given time. I'm using a shared data segment in a dll to store a bool indicating whether the program is already running or not. If it's already running, I have to not run the second instance and give focus to the current running instance.
The jar file calls a native method "canInstantiate()" on a dll to see if there's already an app running. If there isn't, the env and obj are stored in the shared data segment of the dll and we return true. If there is already an instance of the program running, I want canInstantiate call a function on the current instance of the jar (like a callback) to tell it to request focus. It's not working. Can someone tell me if my code is right?
The .h file
#include "stdafx.h"
#include <jni.h>
#include "CardServer.h"
#pragma data_seg("SHARED") // Begin the shared data segment.
static volatile bool instanceExists = false;
static JavaVM *theJavaVM = NULL;
static JNIEnv* theJavaEnv= NULL;
static jobject instanceObject = NULL;
static jmethodID mid = NULL;
static jclass cls = NULL;
#pragma data_seg()
#pragma comment(linker, "/section:SHARED,RWS")
jdouble canInstantiate(JNIEnv *env, jobject obj);
jdouble instantiate(JNIEnv *env, jobject obj);
jdouble uninstantiate(JNIEnv *env, jobject obj);

Can I Call method on one JVM from another through a dll
...The rest of your question merely expands on your title.
And the answer to that question is no.
When you call a method you are executing a "thread of execution." A thread of execution exists only in a single process. It can not exist in another process.
If the dll is doing some interesting things then you could call a method that sets a flag. Data can move between instances. But you would then have to have a thread in that different process monitoring that flag. And sharing data in a dll is not a normal process, so it would have to be coded appropriately.
If all you want to do is set the current focus to the existing application, then that can be done with existing windows functionality. You don't need to do anything special in your dll. You can probably search these forums to find the exact code. If not there are countless examples in windows repositories (like MSDN) on how to do that.

Can one JVM use multiple X Windows displays?

I'm probably clutching at straws here, but is it possible for one JVM to use multiple X Windows displays? Consider this, I've got multiple video cards and each card has a different X session running on it (localhost:0 and localhost:1 for example). I start up a JVM that is displaying to :0 but I also want it to be able to display windows also on :1 without having to instantiate a new JVM.
Is this at all possible and any ideas on how it might be done?

yes, this can be done. I think that you need to set the GraphicsDevice for the JFrames and JDialogs so that they appear in the right place. look at the class GraphicsEnvironment for more information.

Opinions on implementing a JAAS login module to achieve SSO

We are looking at implementing SSO from a sharepoint website to the portal. The users who are accessing the Sharepoint site are using their own computers and are not members of the AD Domain, so they could theoretically be using any computer in the world to access Sharepoint.
the desired user experience looks something like this.
user--login> sharepoint site -no login--
>portal
One of the methods we are looking at to achieve this is to implement a custom JAAS login module that would authenticate the user if they are coming from the Sharepoint site.
I would like to get your opinions on how viable you think this method is. One of the goals of this method is ease of implementation, so if you can think of an easier way to implement this please let us know.
the method is basically this.
1. User logs into sharepoint using their AD username and password and establish an active session with sharepoint
2. user navigates to a link in sharepoint that points to a resource in the SAP Portal
3. we don't want the user to have to login to access the resource when they click on the link
4. to facilitate this, sharepoint has constructed the link in the following way
5. the link is an https link
6. the link has two additional parameters in addition to whatever is necessary to navigate to the resource
7. the parameters are
8. un = the users AD username
9. uh = sha1("secret_password_known_to_both_the_login_module_and_sharepoint" + "username")
10. the user clicks the link and is directed to the SAP portal
11. the sap portal has a custom JAAS login module which performs it's checks before the other login modules
12. the custom module computes ( sha1("secret_password_known_to_both_the_login_module_and_sharepoint" + un)) and then compares the result with uh, if they are equal, the custom login module authenticates the user bypassing any further need for authentication, otherwise authentication passes to the original authentication modules as normal.
If you think there is an easier way, please let us know. We are essentially looking for the easiest/fastest way to implement this functionality that is still secure.

Hey Gary,
I'm currently using Apache running on RedHat that leverage Apache's mod_rewrite module. I've got a bank of 6 reverse proxies sitting in front of an SAP Portal and each proxy runs on a host with dual 3.33GHz processors and 8Gb or RAM. I know... they're waaay over-sized and they pretty much snooze all day.
This is the sole entry point for all SAP users and we sized them to accommodate the "worst case" of about 5000 (potential) named users, concurrently. Realistically, we've only ever had about 1500 unique users hitting the systems in a day (following an upgrade go-live, everybody is curious and wants to log on) and a typical load of about 500 to 750 users in a day.
Never had a real performance problem to speak of. As long as the proxies are tuned properly (ssl cache, sessions, etc.), you should be fine.
Setting header variables and some other "custom stuff" is handled in Perl (need Apache's mod_perl active). We've got a script that's called by all users before being passed to the Portal.
We used IISProxy.dll with an IIS web server a long time ago (5 years maybe?) but opted to can it in favor of the approach described above.
If you ask SAP, they'll recommend you use a WebDispatcher... and that's certainly an option as well.

JAAS Login Module using Deployable Web Service proxy

Hi,
We've created a JAAS Login Module that calls a deployable web service proxy to validate users on Netweaver Portal 2004 SP19. To do this the following steps were taken:
1) created a deployable web proxy named 'SGU_proxy' and uploaded it to server. This project created 2 files: 'SGU_proxy.ear' (the one uploaded) and 'SGU_proxyClientAPI.jar'.
2) created a Java project named 'AgregacaoLoginModule' with a single class to authenticate users, this is the class that calls the web service with the username and password. This project references the deployable web proxy project (Properties > Java Build Path > Projects > checkbox marked next to project SGU_proxy).
3) exported the Java project class, not including the 'SGU_proxyClientAPI.jar'.
4) created a 'J2EE Server Component' > 'Library' project named 'AgregacaoLoginModuleJ2EE'.
On the 'provider.xml' file added 2 jars: 'AgregacaoLoginModule.jar' and 'SGU_proxyClientAPI.jar'. References were made to the standard portal libraries. No references were made to the proxy 'SGU_proxy' or the 'AgregacaoLoginModule' project.
The library was uploaded to the server, everything was ok and no errors were reported.
The login module was configured on the server and is called when users try to acess Portal server.
The problem is that when trying to authenticate users: after getting a reference to the proxy using jndi I get a ClassCastException. Note that this proxy is used in a WebDyn Pro application and is working fine.
The web service client proxy generated the interface 'pt.agregacao.ws.sgu.Servicos' and from jndi I get 'class pt.agregacao.ws.sgu.ServicosImpl'. So this seems to be ok, why the exception?
Is it necessary to had a reference to 'SGU_proxy' on the 'AgregacaoLoginModuleJ2EE' project? If so, how?
Thanks in advance.

The web service client proxy generated the interface 'pt.agregacao.ws.sgu.Servicos' and from jndi I get 'class pt.agregacao.ws.sgu.ServicosImpl'. So this seems to be ok, why the exception?
Is it necessary to had a reference to 'SGU_proxy' on the 'AgregacaoLoginModuleJ2EE' project? If so, how?
Thanks in advance.

Capturing log files from multiple .ps1 scripts called from within a .bat file

I am trying to invoke multiple instances of a powershell script and capture individual log files from each of them. I can start the multiple instances by calling 'start powershell' several times, but am unable to capture logging. If I use 'call powershell'
I can capture the log files, but the batch file won't continue until that current 'call powershell' has completed.
ie. within Test.bat
start powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > a.log 2>&1
timeout /t 60
start powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > b.log 2>&1
timeout /t 60
start powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > c.log 2>&1
timeout /t 60
start powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > d.log 2>&1
timeout /t 60
start powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > e.log 2>&1
timeout /t 60
start powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > f.log 2>&1
the log files get created but are empty. If I invoke 'call' instead of start I get the log data, but I need them to run in parallel, not sequentially.
call powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > a.log 2>&1
timeout /t 60
call powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > b.log 2>&1
timeout /t 60
call powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > c.log 2>&1
timeout /t 60
call powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > d.log 2>&1
timeout /t 60call powershell . \Automation.ps1 %1 %2 %3 %4 %5 %6 > e.log 2>&1
Any suggestions of how to get this to work?

Batch files are sequential by design (batch up a bunch of statements and execute them). Call doesn't run in a different process, so when you use it the batch file waits for it to exit. From CALL:
Calls one batch program from another without stopping the parent batch program
I was hoping for the documentation to say the batch file waits for CALL to return, but this is as close as it gets.
Start(.exe), "Starts a separate window to run a specified program or command". The reason it runs in parallel is once it starts the target application start.exe ends and the batch file continues. It has no idea about the powershell.exe process
that you kicked off. Because of this reason, you can't pipe the output.
Update: I was wrong, you can totally redirect the output of what you run with start.exe.
How about instead of running a batch file you run a PowerShell script? You can run script blocks or call individual scripts in parallel with the
Start-Job cmdlet.
You can monitor the jobs and when they complete, pipe them to
Receive-Job to see their output.
For example:
$sb = {
Write-Output "Hello"
Sleep -seconds 10
Write-Output "Goodbye"
Start-Job -Scriptblock $sb
Start-Job -Scriptblock $sb
Here's a script that runs the scriptblock $sb. The script block outputs the text "Hello", waits for 10 seconds, and then outputs the text "Goodbye"
Then it starts two jobs (in this case I'm running the same script block)
When you run this you receive this for output:
PS> $sb = {
>> Write-Output "Hello"
>> Sleep -Seconds 10
>> Write-Output "Goodbye"
>> }
>>
PS> Start-Job -Scriptblock $sb
Id Name State HasMoreData Location Command
1 Job1 Running True localhost ...
PS> Start-Job -Scriptblock $sb
Id Name State HasMoreData Location Command
3 Job3 Running True localhost ...
PS>
When you run Start-Job it will execute your script or scriptblock in a new process and continue to the next line in the script.
You can see the jobs with
Get-Job:
PS> Get-Job
Id Name State HasMoreData Location Command
1 Job1 Running True localhost ...
3 Job3 Running True localhost ...
OK, that's great. But we need to know when the job's done. The Job's Status property will tell us this (we're looking for a status of "Completed"), we can build a loop and check:
$Completed = $false
while (!$Completed) {
# get all the jobs that haven't yet completed
$jobs = Get-Job | where {$_.State.ToString() -ne "Completed"} # if Get-Job doesn't return any jobs (i.e. they are all completed)
if ($jobs -eq $null) {
$Completed=$true
} # otherwise update the screen
else {
Write-Output "Waiting for $($jobs.Count) jobs"
sleep -s 1
This will output something like this:
Waiting for 2 jobs
Waiting for 2 jobs
Waiting for 2 jobs
Waiting for 2 jobs
Waiting for 2 jobs
Waiting for 2 jobs
Waiting for 2 jobs
Waiting for 2 jobs
Waiting for 2 jobs
Waiting for 2 jobs
When it's done, we can see the jobs have completed:
PS> Get-Job
Id Name State HasMoreData Location Command
1 Job1 Completed True localhost ...
3 Job3 Completed True localhost ...
PS>
Now at this point we could pipe the jobs to Receive-Job:
PS> Get-Job | Receive-Job
Hello
Goodbye
Hello
Goodbye
PS>
But as you can see it's not obvious which script is which. In your real scripts you could include some identifiers to distinguish them.
Another way would be to grab the output of each job one at a time:
foreach ($job in $jobs) {
$job | Receive-Job
If you store the output in a variable or save to a log file with Out-File. The trick is matching up the jobs to the output. Something like this may work:
$a_sb = {
Write-Output "Hello A"
Sleep -Seconds 10
Write-Output "Goodbye A"
$b_sb = {
Write-Output "Hello B"
Sleep -Seconds 5
Write-Output "Goodbye B"
$job = Start-Job -Scriptblock $a_sb
$a_log = $job.Name
$job = Start-Job -Scriptblock $b_sb
$b_log = $job.Name
$Completed = $false
while (!$Completed) {
$jobs = Get-Job | where {$_.State.ToString() -ne "Completed"}
if ($jobs -eq $null) {
$Completed=$true
else {
Write-Output "Waiting for $($jobs.Count) jobs"
sleep -s 1
Get-Job | where {$_.Name -eq $a_log} | Receive-Job | Out-File .\a.log
Get-Job | where {$_.Name -eq $b_log} | Receive-Job | Out-File .\b.log
If you check out the folder you'll see the log files, and they contain the script contents:
PS> dir *.log
Directory: C:\Users\jwarren
Mode LastWriteTime Length Name
-a--- 1/15/2014 7:53 PM 42 a.log
-a--- 1/15/2014 7:53 PM 42 b.log
PS> Get-Content .\a.log
Hello A
Goodbye A
PS> Get-Content .\b.log
Hello B
Goodbye B
PS>
The trouble though is you won't get a log file until the job has completed. If you use your log files to monitor progress this may not be suitable.

Where did multiple saved login names go in ios8 Safari?

Where did multiple saved login names go in ios8 Safari? In io7 you could have multiple logon names for a given webpage, and select which one you wanted, and even though these different names are saved in saved passwords in the Safari settings, I can't access them. Safari now just allows one saved name/password per webpage, and if you want to change this name, you have to turn off saved passwords, and type in the new name and password. Ios7 worked great, why did you mess around with something that worked? If I could, I would roll back to ios 7.

You should get an Open In window that pops up in Safari that allows you to choose the app in which you want to save the PDF. If you do not have an app that works with PDF files (iBooks, Adobe Reader) you cannot save the file anywhere.

Multiple times constructors calling in Myfaces

Hi
i m fasing multiple times constructor calling for myfaces programs
i have created a small web appl. with one text box and one submit button, to test this behaviour.
i have used this sample to
get web page
enter some text value
submit the page
and atlast page get returned to me
i don't understand the multiple times consturctor calling and exact sequence of Getter/Setter calling?
Following are details -
faces-config.xml
<managed-bean>
<managed-bean-name>fileUploadBean</managed-bean-name>
<managed-bean-class>com.dbschenker.dts.model.backingbean.FileUpload</managed-bean-class>
<manged-bean-scope>request</manged-bean-scope>
</managed-bean>
jsp file
<h:inputText id="txtSample" value="#{fileUploadBean.txtName}"/>
<h:commandButton action="#{fileUploadBean.uploadFile}"
image="../../images/upload_0.png"
onmouseover="this.src='../../images/upload_0.png'"
onmouseout="this.src='../../images/upload_1.png'"
onclick="return true;"/>
Backing bean
public class FileUpload {
private String txtName;
public void setTxtName(String txtName) {
System.out.println("Calling Setter... ");
this.txtName= txtName;
public String getTxtName() {
System.out.println("Calling Getter... ");
return txtName==null?"":this.txtName;
public FileUpload() {
System.out.println("Calling Constructor... ");
public String uploadFile() {
System.out.println("Upload Form Submitted... ");
return "";
Output to Console
Calling Constructor...
Calling Getter...
Calling Constructor...
Calling Constructor...
Calling Getter...
Calling Constructor...
Calling Setter...
Calling Constructor...
Upload Form Submitted...
Calling Constructor...
Calling Getter...

Hi
that blog was really good and in depth...
but i have one real time problem with multiple time constructor calling
if you replace text box with file upload tag in my earlier sample program and then following is out put ...
Calling Constructor...
getUploadedFile()...
Calling Constructor...
getUploadedFile()...
Calling Constructor...
setUploadedFile()...
Uploaded File Name - D:\AsnUploadTemplate02.XLS
Calling Constructor... ------------------(.1
Upload Form Submitted...
java.lang.NullPointerException
at com.dbschenker.dts.model.backingbean.FileUpload.uploadFile(FileUpload.java:40)
----------- trailing exception stack trace...
Calling Constructor...
getUploadedFile()...
form this output u can find that my UploadedFile backing bean object gets null just before form submit method...
whereas its has been properly instantiated in setter method,
if constructor (1 wasn't call then object (uploadedFile) can be found in method (FileUpload.uploadFile)
i have also tried to make scope of backing bean Session , but constructor, getter & setter calling sequence doesn't different even after.
i have also considered both of your blog as ---
http://balusc.blogspot.com/2006/09/debug-jsf-lifecycle.html
http://balusc.blogspot.com/2008/02/uploading-files-with-jsf.html
but my problem stands as it is
kindly help

Accessing LDAP in a custom JAAS login module

Hi,
I have developed a custom jaas login module in CE 7.1. I created a java dc which contains a class extending AbstractLoginModule. This DC is deployed on to the server using an EAR DC. I am trying to access LDAP in the custom login module. I am trying to establish an SSL connection to LDAP. For this purpose i have created a custom socket factory class which extends SSLSocketFactory. I used the code below to establish the connection.
 Hashtable<String,String> env=new Hashtable<String,String>();
 DirContext dirContext=null;
 env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory");
 env.put(Context.PROVIDER_URL,ldapURL);
 env.put(Context.SECURITY_PROTOCOL,"ssl");
 env.put("java.naming.ldap.factory.socket", "com.test.ldap.MySSLSocketFactory");
 dirContext=new InitialDirContext(env);
MySSLSocketFactory is the name of custom socket factory.
During a login process, the above code results in error because the connection to LDAP server could not be established. However the same code when executed in a webdynpro DC is working without any problem. What could be the reason for this?
This is the error i could see in defaultTrace
javax.naming.CommunicationException: js24.na.domain.net:636 [Root exception is java.lang.ClassNotFoundException: com.test.ldap.MySSLSocketFactory

Hi,
I used an EJB to perform the LDAP search and called the EJB from the login module. It is working as expected.
