Diff was java add in and stand alone java instance

Hi Guys ,
What is the diff between  was java add in and stand alone java instance ?
Thanks
Sonam

Hai,
SCS is nothing but the SAP Central Services, it is AS Java instance of an SAP system containing the enqueue server and the message server.
JAVA Addin is inserted in exsisting ABAP only instance to have JAVA functionality. JAVA instance is assigned to an ABAP instance. The Internet Communication Manager (ICM) of the ABAP instance starts and stops the associated Java instance as required.
Netweaver JAVA (Stand alone) vs JAVA Addin:
Netweaver JAVA Addin installation is a dual installation that consists of Java and ABAP stack. Addin is required when you are implementing SAP XI (Exchange Infrastructure). Stand alone JAVA is required when you implement SAP EP (Enterprise Portal). It is generally not recommended to use dual installation for EP because this will expose the ABAP layer to the public Internet. So the ABAP stack is often used to host SAP ERP ECC (Enterprise Central Component), SAP CRM, SAP SCM, etc.,
Since the information hosted on ABAP stack is more sensitive in nature you are recommended to install Portal on the Netweaver AS Java server (Stand alone JAVA server).
By doing this you will be able to fully utilize the system resources for the portal and ensure good performance.

  • Communication between servlet(client behavior) and stand alone java program

    Hello all:
    I need to send a message (ascii characters sequence) from a servlet to a java program, but I'm not sure what is the best way to get it: socket, JMS or other mechanism that I don't know.
    Is the servlet who is operating how client behavior.
    Please, any comment will be appreciated, regards,
    Ulises.

    You can always start a ServerSocket on the client (kinda sounds funny, doesn't it) which will accept connections. You then open a plain old Socket on the server to connect to the client's listener. (Note, this is the reverse of a normal set-up). Once you have the connection established, you will call getOutputStream() to get a stream to write to. Likewise, you will call getInputStream() to read the data sent. You will want to investigate the java.net.* and java.io.* libraries.

  • Calling a web service through SSL via a stand alone java class

    HI,
    I am trying to call a web service through SSL via a simple stand alone java client.
    I have imported the SSL certificate in my keystore by using the keytool -import command.
    Basically I want to add a user to a group on the server. Say I add a user user 1 to group group 1 using an admin userid and password. All these values are set in an xml file which I send to the server while calling the server. I pass the web service URL, the soap action name and the xml to post as the command line arguments to the java client.
    My xml file(Add.xml) that is posted looks like :
    <?xml version="1.0" encoding="UTF-8"?>
    <SOAP-ENV:Envelope
    xmlns:xsi = "http://www.w3.org/1999/XMLSchema-instance"
    xmlns:SOAP-ENC = "http://schemas.xmlsoap.org/soap/encoding/"
    xmlns:SOAP-ENV = "http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:xsd = "http://www.w3.org/1999/XMLSchema"
    SOAP-ENV:encodingStyle = "http://schemas.xmlsoap.org/soap/encoding/">
    <SOAP-ENV:Body>
    <namesp1:modifyGroupOperation xmlns:namesp1 = "/services/modifyGroup/modifyGroupOp">

    <users>
    <userName>user1</userName>
    </users>
    </namesp1:modifyGroupOperation>
    </SOAP-ENV:Body>
    </SOAP-ENV:Envelope>
    I call the client as:
    java PostXML https://com.webservice.com/services/modifyGroup "/services/modifyGroup/modifyGroupOp" Add.xml
    I my client, I have set the following:
    System.setProperty("javax.net.ssl.keyStore", "C:\\Program Files\\Java\\jre1.5.0_12\\lib\\security\\cacerts");
    System.setProperty("javax.net.ssl.keyStorePassword", "password");
    System.setProperty("javax.net.ssl.trustStore", "C:\\Program Files\\Java\\jre1.5.0_12\\lib\\security\\cacerts");
    System.setProperty("javax.net.ssl.trustStorePassword", "password");
    But when I try to execute the java client, I get the following error:

  • How to call a stand alone java application from ADF BC JSP, struts or JSF

    Hi,
    My requirement is that there are utilities or stand alone java applications that I want to call from our existing applications.
    We have two seperate applications one ADF BC Struts application we developed using JDeveloper 10.1.2 and another ADF BC JSF application we developed using JDeveloper 10.1.3.2.
    We want to integrate applications like JTwain and others to help us in scanning. The application will be placed on the same server as our application. How can I do this without loosing all the current session information.
    Please help.
    Thanks and regards,

    There are two possible solutions.
    First, if the tool or application you want to integrate, has an Java-API you can use this api and integrate the tool in your application (using one or more jars you add to the classpath).
    Second, if the tool has no java api, you can call the tool via runtime.exec(...) as a shell process. This way you open a command shell in you application and execute the tool like you do on a normal command shell.
    For tide integration and control I recommend the first approach. The second one is only for those tools which don't offer a java api.

  • Installation WAS ABAP UC + WAS J2EE Add In..and XI

    Hello everybody,
    Could anyone help me with this issue ??
    I am going to install WAS ABAP and WAS J2EE Add in and after that do the XI installation.
    I am reading the installation guides and I have some doubts about "Hardware and SOft Requirements Section".
    I am going to do a Central System Installation (WAS ABAP + WAS JAVA Add in)
    I have read the two installation guides: WAS ABAP and WAS J2EE.
    Somewhere I read that I have to add requeriments. For example, if I am going to install CI and DB on the same server, then I have to add RAM for CI and RAM for DB.
    The question is:
    In the installation guide for WAS ABAP, Database Requeriment Disk is 14 GB (Unicode)
    And in the installation guide for WAS JAVA, Database Req. Disk is 14 Gb (Unicode)
    Have I to add 14 + 14 ?? Or 14 Gb is OK for the database with the two schemas ??
    Same is for Paging File ?? I am 64 bit server.
    It is a Development System
    Many, many thanks !!

    We have a ABAP/J2EE 6.20 system running with only 8GB ram total on the system and we do get some swapping but for a development I would say we see great performance.
    XI I can'T say though...

  • Error in obtaining token using TokenManager thru a stand-alone java appln

    I am trying to use the IS Java APIs to connect to the directory server and insert a user in the directory from a stand alone java appln.

    The credentials provided in the code are correct. What could be the cause of the error?
    TIA,
    siddharth.

    Tthis class is undocumented and this is the reason why you will not find any documentation. This is not the correct way for a client to authenticate to the is in v6. You need to use the JAAS API. I do not believe that the AuthPrincipal sample works in 6.
    The package for the class is com/sun/identity/authentication/internal/

    You didn't post the stack trace from the server, but I'm guessing it's complaining about the QName class. Sun changed the QName class in JDK 1.5 wreaking havoc on JDK 1.5 clients that use JDK 1.4 servers and attempt to pass a QName object from one to the other. If your client uses JDK 1.5, your sever will need to use a QName class which is compatible. The file liquiddata/lib/wls90interop.jar contains a QName class that is compatible with the one in JDK1.5. You can put it first in the classpath of your server.
    If you already have wls90interop.jar first in the classpath of your server, then, for your client, you need to either (1) use the Sun JDK 1.5; or (2) put wls90interop.jar first in the classpath of your client (if you are running JDK 1.4).

    please help me in resolving the above problem
    advance thanx to all those who intend to reply
    please provide me a proper resolution

    I think the appserver uses com.sun.enterprise.naming.SerialInitContextFactory on the server side to register different resources. Anything registered with SerialialInitContextFactory cannot be resolved with a CNCtxFactory.
    Can you try using SerialInitContextFactory on the client side.

  • Database connection pool to stand alone java class

    Hi all,
    I would like to know the best way to use a database connection pool with a stand alone java class.
    In my web applications I usually use JDBC Data Source version 5 to connect to my database. In this case, I connect to an Oracle database. But in this scene, I've a WebSphere Application Server to provide this connection pool. But for stand alone applications, I don't know how to do because I don't have a Application server to run on.
    Can enyone help me with this beginner question?
    Best regards.

    I tried to find the pool class I created but it must be on another CD. Anyway, you can easily create a number of connections and place them on a stack (your own or java's). When you need one, pop it off. When you are finished, push it back.
    Good luck.

  • Can I backup between a testversion and stand-alone version?

    Can I backup between a testversion and stand-alone version?

    You are correct, the CC version is activated with your Adobe ID and password after you have signed up for the creative cloud plan. You can uninstall that CC version and install the standalone. It is the same program, and will open the same catalog. You don't need to back up anything. Just change over to the standalone program and start Lightroom. Everything will function just the same6.

    can someone pls help me with java on my macbook pro because after i download the mountain lion java has died and i need java to see streaming quotes from stock market

    Java is no longer included in Mac OS X by default. If you want Java, you will have to install it.
    However, note that you should think twice before installing Java for such a trivial need as looking at stock market quotes. There are other ways to get that information that don't involve Java, and using Java in your web browser is a HUGE security risk right now. Java has been vulnerable to attack almost constantly for the last year, and has become a very popular, frequently used method for getting malware installed via "drive-by downloads." You really, truly don't want to be using it. See:
    Java is vulnerable… Again?!

  • Open VI Reference and Stand-Alone

    Hi!
    Using LabView 7.1 under XP I made a vi which creates a report in Excel format.
    The vi runs correctly but, If I do a Stand-Alone application of that vi, an error 7
    (problem occured at Open VI Reference in New Report.vi) appears when I launch the exe. Why ?
    Someone has any idea ?
    Thanks

    I my particular case, I only add the vi's that are dynamically called in the Source Files list of the Build Application (see attachment). I did nothing else !
    On the other hand, I have Oslo observed that the "Current Vi's path" gives for example:
    c:\directory1\directory2\Library.llb\viName.vi
    when testing within LV while it gives
    c:\directory1\directory2\Application.exe\viName.vi
    when running the EXE. I have first expected to get
    c:\directory1\directory2\Application.exe
    when running the EXE and thought it was a bug of LV. However, there is no bug (here) and "Current Vi's path" works as described in the documentation:
