Add JAVA STACK

Hello All,
I want to install Java stack on already running Ecc 6.0 (windows _SQL).Server is installed 6 months back.Do i have to take any precautions ? I mean complete offline backup is ok.
As fas as i know performance of the server will be one of the issue after adding java stack.
any other thing which i have to consider before this ? and Do i have to just run sapinst and then Add java+abap part only ????
Thanks in advance
Rohit

Hi Markus,
Thanks for the reply ...i have to update both stacks that is ok.
my question is Can i add java stack now(after 6 months of abap stack)?
Do i have to take any precautions before this?
Will it affect/harm any other things like files etc?
The procedure is simple ? i mean to say ...i just have to run spainst and select Add java + abap option?
anything else???
Thanks in advance.

Can we add Java Stack after complete installation

We have already installed SAP ECC 6.0. While installation, we had opted only for ABAP stack. Can we add the Java stack now?
Regards.

Hi,
Yes you can install java server on existing ABAP but
If you have an existing ABAP central instance + ABAP dialog instance and
you want to install Java Add-in to the central instance, you first need
to uninstall the ABAP dialog instance, then Install the Java central
instance add-in and then install an ABAP+Java Dialog insntance.
Please refer ABAP+Java instalation guide.

For an SAP enterprise(4.7), how to add java stack during upgrade to ECC6.0?

Source release: an R/3 4.7 32bit
Target release: ECC6.0 64bit (abap+java)
My plan is to go over the following upgrade steps:
4.7 32bit-> ECC abap only 32bit ->ECC abap 64bit -> install java stack.
Is this the best way?
Thanks a lot!

Hi,
Its always best to go to the enhanced and latest version.
_+4.7 32bit-> ECC abap only 32bit ->ECC abap 64bit -> install java stack.+_
the above step will increase only only the cost.
If ur going for just practice purpose, then no issues u can go for it.
But its always good to go for
4.7------> Ecc(ABAP + JAVA) together.
coming to 32bit and 64 bit. Some constraints are there. If u look at Ecc 6- SR3, it will only support 64 bit.
Look at all those sections and go for upgrade.

Ravi

How to add abap stack to existing NW Java engine- for XI installation

Hi All,
I am having a netweaver Java Stack installed on my system. I would like to install XI - in order to install Xi ,I guess the system should be ABAP + Java. But since I am having java based engine, I would like to add ABAP stack to it. So, my question how to add an ABAP stack to already existing JAVA/J2ee engine.
So what this process is known as-- Is it upgrading or New Installation. Because I need the guide and CD's for it.
Can any one tell me which Guide(Install/upgrade/Master) wud help me.
Thanks

Hello
If you are adding XI 7.1 check this page: http://service.sap.com/~form/sapnet?_SHORTKEY=01100035870000702775&_SCENARIO=01100035870000000202&
If you are adding XI 7.0 check this one: http://service.sap.com/~form/sapnet?_SHORTKEY=01100035870000659894&_SCENARIO=01100035870000000202&
You should read the master guides and install the new usage type on top of your current installation but check the SAP notes about it first.
If what you want is to install XI 3.0, that is if you have an existing v6.40 java stack, I think the operation is not recommended/supported by SAP, you should install a separate instance.
Hope it helps.

AS Java Stack as Add-in to ABAP Stack in case of Dual Instance

Short Text
AS Java Stack as Add-in to ABAP Stack
Long Text
Hi
We are upgrading from SRM 3.0 to 5.0.
We will need to install JAVA stack as add-in to ABAP stack. SRM 5.0
need both ABAP and JAVA stack (becuase of integrated ITS and IPC).
We have one box for DEV and QA and they are installed as separate
instance (dual instance).
Can we install JAVA stack for both instance separately?
Or do we have to split the dual instancing development system into two
separate standalone system
Please advise
Regards
Manisha

Hi Mike
Thanks for your response.
We do not have MCOD installation.
Our DEV and QA installed on same physical same server but they they their own database and separate instance of ABAP stack.
Some concern have been raised that if we install JAVA stack as add-in on DEV instance, QA instance will be impacted. Because you can not have two separate JAVA stack on same server.
Please advise if above concern is true

Manisha

Hi Manisha,
If the box is properly sized I feel that in the same box itself you can have 2 java instances (just you have to take care of the instance number).
Also another point which you can consider is that whether your platform is 32 bit ot 64 bit.
So if it is 32 bit what I recommend is to use new hardware and seperate the instances.
Any how it is possible technicall to have 2 java instances in one server.

Difference between add-in Java-Stack and standalone stacks

Hello experts,
is there any difference between a Java-Stack as add-in in ABAP AS and two standalone stacks, aside from that the standalone systems are physically seperated. What other reasons are there to choose the one or the other? Is it performance or scalability? Are there any differences for developers (for example on XI or BI) or is the difference only important for administrators?
Best regards,
David

Hi David,
I've just found the following document is uploaded on SDN.

Hi There
Can any one please make me clear about the adavantages of JAVA stack on ECC6.0, how does it helps our business, as tehre are no JAVA relaetd components in our environment , now we are on ECC6.0 ABAP stack, if this is the case how to go ahead with JAVA stack, I mean to ask the of make my ECC6.0 as a dual stack , must i choose JAVA system as an Add-on to existing ECC ABAP stack or must i go for another stand akone JAVA box, which option is the correct one.
Now we are on BW3.0
got a plan to upgrade to BI 7.0 , is JAVA system required for that or BI 7.0 only runs on ABAP stack?please let me know how to implemnt the JAVA stack for the existing system.Thanks in advanse.

Single-Sign-On (SSO) configuration on JAVA Stack through HTTP Header method

Hello SDN community,
in the context of a Proof of Concept, we are testing the integration of Microsoft Sharepoint Portal with SAP Backend (addin) systems.
As the architecture impose use an external scenario (access from the internet), we couldn't use the Kerberos (SPNego) solution and thus we chosed the http header solution which in short uses an intermediary web server (in this case the IIS of the MOSS solution) which will act as authority.
I miss information on how the workflow works for this http header authentication method. Through the visual administrator of the addin JAVA stack, it is possible to configure each application with a customized authentication (a choice of security modules). But this all that I know.
My task is to configure SSO. From a sharepoint portal, the user should be able to access Web Dynpros and BSPs. I imagine that the very first call to a webdynpro or bsp (or maybe when we log on the sharepoint portal), the request to the WDP or BSP will first be forwareded by the intermediary server to the JAVA stack (or is it the SAP dispatcher that has to be configured).
Is there an application to be built on the java stack to deal with the authentication, modify http header?
What will the Java stack return? a sap long ticket? a token?
How will the redirect work (to by example a BSP which is in the ABAP stack)?
SAP preconise to secure with SSL the link between the intermediary web server and the JAVA stack, is IP restriction also a solution?
A lot of questions about how this SSO http header should work,
I would be very greatful for any help, or info,
Kind regards,
Tanguy Mezzano

Hi Tanguy,
to tell you the truth I'm really unsure about what you are trying to achieve. When I started posting to your thread I thought all you wanted was trying to access your J2EE engine via Browser and authenticate against the engine using HTTP Header Variables. Nevermind:
Here are some answers to your question:
in fact I did succeed, the problem was that even after domain-relaxation done by the J2EE, I had to change the domain of th SAP cookie to the bbbb.domain.com to be understood (I would have thought that all hosts in/under domain .domain would have accepted such a cookie but it seems that no...).
The server does not care about the domain because Cookies in an HTTP Request do not contain any domain information. The domain is just important when the Cookie is set by the server so your Client (Browser) will know in which cases the Cookie may be sent or not. So if your domain is xxx.yyy.domain.com and your cookie is issued to .domain.com then your Browser will definitely sent it to all hosts under .domain.com (This includes xxx.yyy.domain.com etc.)
My current scenario is: in a first request get a SAP Logon Ticket from the Java Stack, then change its domain and then directly call the backend with it.
You can do that but there is no Client involved in this scenario. So this is useful if you just want to test the functionality (e.g. authentication to J2EE using Header Variables (This works finally!!!) and then use the fetched Logon Ticket to test SSO against any trusted Backend!!)
So everything's is in a Java Client application without using any redirection.
If I understand you, you're solution is from the Browser call a servlet (which is deployed on the Java Stack and has no authentication schema) by passing to it our http header.
No, you should initially authenticate somewhere! I thought that maybe you had some resource you access before accessing the Java Stack. This could be any application (e.g. deployed on a Tomcat or JBOSS or other server or if you like even SAP J2EE). After authenticating there you are aware of the username and could use it to procceed (e.g. Authenticate against the J2EE using the same user and HTTP Header authentication for that particular user!)
That servlet will transfer the http header (with the HttpClient app) in order to get from the Java Stack a SAP Logon ticket, and then to redirect to the resource and by sending back the cookie in client browser. Am I correct?
This was just a suggestion because I realized that there was no Client ever involved in any of your testing (looked strange to me!). I was just thinking that it would be easier for you to just get the Cookie into your Browser so your Browser would do the rest for you (in your case finally send the Logon Ticket Cookie to your Backend to test SSO using Logon Tickets!).
The AuthenticatorServlet somehow serves as a Proxy to your client because your client is not able to set the Header Variable. That's why I initially suggested to use a Proxy (e.g. Apache) for that purpose. The problem is just that if you use a Proxy you will have to tell it somehow which username it should set in the Header Variable (e.g. using a URL Parameter or using a personalized client certificate and fetch the username (e.g. cn=<username> from the certificate!)
This way of doing would simplify the calls for sso for each new application needing authentication, instead of having all code each time in it...
I'm stuck again! Do you want to authenticate an End User or do you want to authenticate an application that needs to call any resources in your Backend that requires authentication?
So my problem now, is how to call the servlet from the client browser:
I'm trying to call my servlet from the browser but I don't succeed. I am able to understand how to reach a jsp from the Java Stack, but not to reach a servlet. I don't find the path to my servlet:
<FORM method="POST" action="SSORedirect2" >
A JSP is a servlet too. There is just no JAVA Class involved!
You do not need any POST Request to invoke a Servlet.
I see that my servlet is deployed, but I don't how what path to give to my form to invoke the servlet, here follows my web.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE web-app (View Source for full doctype...)>
- <web-app>
<display-name>WEB APP</display-name>
<description>WEB APP description</description>
- <servlet>
<servlet-name>SSOredirect2</servlet-name>
<servlet-class>com.atosorigin.examples.AuthenticatorServlet</servlet-class>
</servlet>
- <servlet>
<servlet-name>SSORedirect2.jsp</servlet-name>
<jsp-file>/SSORedirect2.jsp</jsp-file>
</servlet>
- <security-constraint>
<display-name>SecurityConstraint</display-name>
- <web-resource-collection>
<web-resource-name>WebResource</web-resource-name>
<url-pattern>/*</url-pattern>
<http-method>GET</http-method>
<http-method>POST</http-method>
</web-resource-collection>
- <auth-constraint>
<role-name>DefaultSecurityRole</role-name>
</auth-constraint>
</security-constraint>
- <security-role>
<role-name>DefaultSecurityRole</role-name>
</security-role>
</web-app>
If you have an AuthenticatorServlet Class all you need is to add the Servlet Mapping in your web.xml file
e.g.
<servlet>
<description>
</description>
<display-name>AuthenticatorServlet</display-name>
<servlet-name>AuthenticatorServlet</servlet-name>
<servlet-class>com.atosorigin.examples.AuthenticatorServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>AuthenticatorServlet</servlet-name>
<url-pattern>/AuthenticatorServlet</url-pattern>
</servlet-mapping>
You can directly call the Servlet in your Browser by calling the URL provided in the url-pattern of your Servlet mapping ( in this case /AuthenticatorServlet). The engine will invoke the Class "com.atosorigin.examples.AuthenticatorServlet" in the background and do whatever you defined there!
I have also to pass my http header and the redirectUrl in the GET request.
If you like! I just suggested this for testing purposes. As I stated before you need a way to tell your proxy (or in your case AuthenticatorServlet) which user should be set when calling the Engine in order to authenticate using HTTP Header. You could use the URL Paramater to define the user you actually want to use when you set the Header Variable.
I just introduced the redirectURL because you were talking about redirects all the time. So if you finally want to call the Backend you could define the Backend URL in the redirectURL Parameter and the Servlet will make sure that you are redirected to this location after the whole process!
Thx for your input very helpful,
But again 0 points
Cheers

'A file or directory doesn't exist' error during java stack update

Dear All,
I've done a fresh installation of solution manger system on IBM iseries box (OS400 & DB2 combo).
As part of post installation activity, I've updated the kernel patch, updated the ABAP stack to sp4, and am currently doing the java stack update.
I'm struck with one error. The log file shows:

I've checked the file system and found that the directory META-INF is not present in /../../global/j2eeclient
Please suggest a solution.
Thank You.

Hi,
This is an easy solution:
From the OS command line, do WRKLNK, go to /usr/sap/SLMS/global/j2eeclient, at the top where it shows the directory, do a copy on this. Then at the command line type MD, do F4, paste the directory name in the first line, then after j2eeclient add /META-INF'
IMportant*** Make sure the full directory name is in single quotes.*
*On the next 2 lines change INDIR to RWX. Then press enter and re-run your job. If you have any problems let me know.

Couldnt upgrade the java stack after upgrading the abap to ehp1

Hi
I have upgarded the system to ehp1 but i couldnt continue to upgarde the java stack to 18th patch.The reason is it coudlnt find the file JSPM02P-2-20002796.SCA. I couldnt find this file . i couldnt find only this file JSPM02P_4-20002796.SCA . I tried to put this file in inbox and tried to run the jspm but it is not recognizing this as a valid file and its expecting JSPM02P-2-20002796.SCA. I couldnt find this file can anyone suggest me where i could find this file.
Thanks and Regards
MA.Sreenivasan

When you download the files, be sure to select "Save As File", which next to the "Add to Download Basket" button. Copy that SPStab.xml file to your EPS/in directory. Without that, it won't recognize the files even if they are there.
