What are valid RMI types?

I read in the J2EE Tutorial several times that arguments and return types must be valid RMI types.
What does that mean?

valid RMI types:
which are either primitive types, object types implementing (even indirectly) java.rmi.Remote, or object types implementing (even indirectly) java.io.Serializable.
Here is a list of the types that can be passed as parameters or returned in Java RMI:
Primitives: byte, boolean, char, short, int, long, double, float
Java serializable types: any class that implements or any interface that extends java.io.Serializable
Java RMI remote types: any class that implements or any interface that extends java.rmi.Remote

    Hi Sushma,

    It has a list of the algorithms, which are pretty disappointing, I must say. No Random Forests? No ensembling methods? Given that it's using R algorithms, I must say this is a missed opportunity to beat products like SPSS and SAS at their own game. If SAP were to include this functionality, they would be the only BI vendor capable of having a serious predictive tool integrated with the rest of the platform.... but this looks pretty weak.
    I can only hope a later release will remedy this - or maybe the SDK will allow me to create what I need.
    As things stand, I could built a random forest using this tool, but I would have to use a lot of hardcoded SQL to make it happen. And if I wanted to go down that road, I could use the algorithms that come with the Microsoft/Oracle software.
    Please let me be wrong........

    What are the different types of parameters available in function builder and where do we use them.

    The different type of parameters available in FM are
    Import - They are used to pass the values to the function module.
    Export- They are used by FM to pass the result back to the calling program.
    Changing - The variables are passed to the FM and can be changed during the FM processing.
    Tables - Internal tables can be passed to the FM (it works similar to changing parameter).

  • What are valid and invalid email address characters

    What are valid and invalid email address characters in Exchange 2010, for example can you have Conan.O'[email protected] is there a document that shows the valid and invalid sysmbols?

    Hi
        The format of email addresses is
    local-part@domain where the local-part may be up to 64 characters long and the
    domain name may have a
    maximum of 253 characters - but the maximum 256 characters length of a forward or reverse path restricts the entire email address to be no more than 254 characters.<sup id="cite_ref-0">[1]</sup>
    The formal definitions are in RFC 5322 (sections 3.2.3
    and 3.4.1) and RFC 5321 - with a more readable form given in
    the informational RFC 3696<sup id="cite_ref-1">[2]</sup>
    and the associated errata.
    Local part
    The local-part of the email address may use any of these
    ASCII characters
    RFC 5322 Section
    3.2.3:
    Uppercase and lowercase English letters (a–z, A–Z) (ASCII: 65-90, 97-122)
    Digits
    0 to
    9 (ASCII: 48-57)
    Characters
    !#$%&'*+-/=?^_`{|}~ (ASCII: 33, 35-39, 42, 43, 45, 47, 61, 63, 94-96, 123-126)
    Character
    . (dot, period, full stop) (ASCII: 46) provided that it is not the first or last character, and
    provided also that it does not appear two or more times consecutively (e.g. [email protected] is not allowed.).
    Special characters are allowed with restrictions. They are:
    o   
    Space and
    "(),:;<>@[\] (ASCII: 32, 34, 40, 41, 44, 58, 59, 60, 62, 64, 91-93)
    The restrictions for special characters are that they must only be used when contained between quotation marks, and that 3 of them (The
    space, backslash \ and
    quotation mark " (ASCII: 32, 92, 34)) must also be preceded by a backslash
    \ (e.g.
    A quoted string may exist as a dot separated entity within the local-part, or it may exist when the outermost quotes are the outermost characters of the local-part
    (e.g. abc."defghi"[email protected] or
    "abcdefghixyz"@example.com are allowed. Conversely,
    abc"defghi"[email protected] is not; neither is
    abc\"def\"[email protected]). Quoted strings and characters however, are not commonly used.
    RFC 5321 also
    warns that "a host that expects to receive mail SHOULD avoid defining mailboxes where the Local-part requires (or uses) the Quoted-string form".
    The local-part "postmaster" is treated specially - it is case-insensitive, and should be forwarded to the server's administrator. Technically all other local-parts
    are case sensitive, therefore [email protected] and [email protected] specify different mailboxes. However most organizations treat uppercase and lowercase letters as equivalent, and also do not allow use of the technically valid characters
    (space, ? and ^). Organizations are free to restrict the forms of their own email addresses as desired, e.g.,
    Windows Live Hotmail,
    for example, only allows creation of email addresses using alphanumerics, dot (.), underscore (_)
    and hyphen (-).<sup id="cite_ref-2">[3]</sup>
    Systems that send mail must be capable of handling outgoing mail for all valid addresses. Contrary to the relevant standards, some defective systems treat certain
    legitimate addresses as invalid and fail to handle mail to these addresses. Hotmail, for example, refuses to send mail to any address containing any of the following standards-permissible characters:
    !#$%*/?^`{|}~
    Domain part
    The domain name part of an email address has to conform to strict guidelines: it must match the requirements for a
    hostname,
    consisting of letters, digits, hyphens and dots. In addition, the domain part may be an
    IP address
    literal, surrounded by square braces, such as jsmith@[192.168.2.1], although this is rarely seen except
    in email spam.
    Examples
    Valid email addresses
    <tt>[email protected]</tt>
    <tt>[email protected]</tt>
    <tt>[email protected]</tt>
    <tt>much."more\ unusual"@example.com</tt>
    <tt>very.unusual."@"[email protected]</tt>
    <tt>very."(),:;<>[]".VERY."very@\\\ \"very"[email protected]</tt>
    Invalid email addresses
    <tt>Abc.example.com</tt> (an @ character must separate the local and domain parts)
    <tt>[email protected]</tt> (character dot(.) is last in local part)
    <tt>[email protected]</tt> (character dot(.) is double)
    <tt>A@b@[email protected]</tt> (only one @ is allowed outside quotation marks)
    <tt>a"b(c)d,e:f;g<h>i[j\k][email protected]</tt> (none of the special characters in this local part
    is allowed outside quotation marks)
    <tt>just"not"[email protected]</tt> (quoted strings must be dot separated, or the only element making
    up the local-part)
    <tt>this is"not\[email protected]</tt> (spaces, quotes, and backslashes may only exist when within
    quoted strings and preceded by a slash)
    <tt>this\ still\"not\\[email protected]</tt> (even if escaped (preceded by a backslash), spaces, quotes,
    and backslashes must still be contained by quotes)

  • What are Validation and simulator

    can any one explain what are Validation and Simulators are ???
    what is there importance and how they work in SAP ??
    Regards,
    Milindkumar

    Are you referring to validation rules and simulations? Whereby validations allow the checking of values and combinations of data as they are being entered in SAP. Because the data is validated before it is posted, only correct information enters the system. For example if you have a cost center X that should not post to account Y. You create a validation that checks to see if cost center X is entered whether the account is Y. If the account is Y the validation will stop the entry from being made.
    Simulations normally are when data is checked for accuracy or verfied before posting. Simulations usually allow the verification of data by displaying that entries that will post or will be created only after the post button or process occurs.

  • What are the query types,Objects CRM provides for third party

    What are the query types,Objects provided by the CRM so that it can be called by third party for integartion pupose.

    First, that statement - and those materials - refer to the "legacy" StreamInsight query/adapter model. They do not refer to how things work with the Reactive model introduced in version 2.1. Specifically, it talks about Dynamic Query Composition (DQC).
    You cannot use a deployed Observable in another instance of StreamInsight. You may be able to use them across applications in the same instance - off the top of my head, I'm not sure. I'm getting ready to get on a plane but will take a look at it later.
    Typically, however, applications act as containers (comparable to .NET AppDomains) so I don't think that you'd be able to do this easily. That said, the code and assemblies
    can be reused across multiple instances/applications. You would have separate instances of the classes involved but you would be able to reuse the query logic. That's a common use case.
    Can you be more specific about your use case and what you are trying to accomplish here? It's possible that there are alternative ways to do what you are trying to do.

    Thanks in advance .

    Hi,
    1) Invalid characters while loading: When you are loading data then you may get some special characters like @#$%...e.t.c.then BW will throw an error like Invalid characters then you need to go through this RSKC transaction and enter all the Invalid chars and execute. It will store this data in RSALLOWEDCHAR table. Then reload the data. You won't get any error because now these are eligible chars done by RSKC.
    2) IDOC Or TRFC Error: We can see the following error at u201CStatusu201D Screen:Sending packages from OLTP to BW lead to errorsDiagnosisNo IDocs could be sent to the SAP BW using RFC.System responseThere are IDocs in the source system ALE outbox that did not arrive in the ALE inbox of the SAP BW.Further analysis:Check the TRFC log.You can get to this log using the wizard or the menu path "Environment -> Transact. RFC -> In source system".Removing errors:If the TRFC is incorrect, check whether the source system is completely connected to the SAP BW. Check especially the authorizations of the background user in the source system.Action to be taken:If Source System connection is OK Reload the Data.

  • What are all the types of Function module?

    Hi,
    What are all the types of Function module.
    Pls reply me.

    Hi,
    Function modules are one element. There are no types. However sometimes an RFC enabled function module is referred to as RFC Function module, but really it is just a function module. Also BAPIs are function modules, but are usually referred to as just BAPI as opposed to BAPI Function module.
    There is no different function module types , but calling the function module will be different.
    check this function calls syntax
    1. Calls a function module:
    - CALL FUNCTION func.
    2. Call a function module in a different mode (asynchronous Remote Function Call):
    - CALL FUNCTION func STARTING NEW TASK taskname.
    3. Call a function module in the update task:
    - CALL FUNCTION func IN UPDATE TASK.
    4. Call a function module in a remote system (Remote Function Call, RFC ):
    - CALL FUNCTION func DESTINATION dest.
    5. Asynchronous call to a function module with transactional processing (transactional Remote Function Call):
    - CALL FUNCTION func IN BACKGROUND TASK.
    qRFC with output queue
    6. Call a function module that can be activated in the context of enhancements:
    - CALL CUSTOMER-FUNCTION func.

  • What are the output type and Tcodes?+

    What are the output type and Tcodes?

    hi,
    ex-how to config output type.
    You will assign output types using Transaction NACE.
    Do the follow steps to assign output type
    1)Select Application Type V2 which will have description Shipping.
    2)Click on Output types button.
    3)Go to change mode by pressing Ctrl+F4.
    4)Select one output type which already exists
    5)Do Copy As(F6)
    6)Give your output type against Output Type field.
    7)Under General data Tab, Give Program and Form routine and Save the data.
    i think it a work of functional guy but at senior level i think it is not a big deal for abaper.
    Check the following documentation
    In NACE t-codewe have the application for each one. based on the application output type can be defined, based on output type script and print progrma can be defined.
    If suppose data can be read from EDI then we should go for condition records.
    So whenever we execute the script first composer checks the output type and then execute the program. in program whenever opn form FM will be populate then script will open first. After that again program till another FM will populate if it then script will populate........like it is cycle proces. Composer does all these things and at last it will submit that output to spool.
    Go to the Transaction NACE.
    choose the related sub module.. like billing or shipping
    doubel click on Output Types
    Choose the Output Type for which whcih you wanted your script to trigger
    Then select the Output Type and double click on Processing Routine
    Then go to create new entries--> Select the Medium (1- print output), then enter your Script and Print Program detls --> Save and come out
    Now go to the Transaction (for which you have created the output type)... Issue output--> Select the output type --> Print....
    Device Types for SAP Output Devices (Detail Information)
    Definition
    The device type indicates the type of printer to be addressed. When you define an output device, choose the name of the device type that was defined in the SAP System for your printer model, such as Post2 for a PostScript printer. In the case of frontend printing under Microsoft Windows, you can also use the generic (device-independent) device type SWIN.
    The system uses the information in the device type to convert a document from the internal SAP character representation (spool request in OTF or in text format) to a device-specific, print-ready data stream (output request). Since a device type specifies attributes that apply to all devices of a certain model, it can be shared among device definitions. For example, all devices in the SAP spool system that are compatible with Hewlett-Packard LaserJet IIID printers would use the HPLJIIID device type.
    You should not confuse the device type with the printer driver. The device type is the total of all attributes of an output device that the SAP System must know to control the output device correctly, such as control commands for font selection, page size, character set selection, and so on. These attributes also include the printer driver that SAPscript/Smart Forms (the SAP form processor) should use for this printer. The SAPscript printer driver that is to be used for devices of this type for output formatting is therefore only an attribute that the device type specifies.
    How do I choose the correct device type?
    • In most cases, the SAP System already provides the appropriate device type for the printer type for the printer model that you want to use.
    These standard device types are completely defined and need no modification or extension before you use them in device definitions.
    • You can also download missing device types from the sapserv server. For a current list of the supported device types, see SAP Note 8928 in the SAP Service Marketplace.
    • Most printers can be controlled using a generic format, such as PostScript. They can be switched to a mode that is compatible with one of the standard printers for which an SAP device type is available. In this case, a supported model is emulated.
    • Almost all printers are delivered with Microsoft Windows printer drivers. The system can control these printers with the generic (device-independent) device type SWIN. The Microsoft Windows spool system then performs the processing of the print data.
    • If the specified device types are not available, and generic device types cannot be used, you must create your own device type or edit a copy of an existing device type. We recommend that only those with specialist knowledge of the SAP Spool System and printer driver code do this. For more information, see Defining a New Device Type .
    Attributes of a Device Type
    A device type is distinguished by the attributes listed below. If you change an existing device type or create a new device type, you must change at least some of these attributes.
    • Character set: A character set specifies the codes with which characters must be represented in the print-ready output stream (output request). This code replaces the generic SAP characters set that is used internally by the SAP spool system (spool request).
    • Printer driver: You can specify different printer drivers for printing SAPscript documents and ABAP lists.
    • Print controls: Print controls represent printer operations, such as boldface or changing the font size. These print control are replaced by printer-specific commands during the creation of the output request from a spool request.
    • Formats: Formats specify the format supported by the SAP system. The system differentiates between SAPScript formats (DINA4 and LETTER) and ABAP list formats (X_65_132 = 65 rows/132 columns).
    • Page format: A page format is the interface between a format and SAPscript. It specifies the paper dimensions with which SAPScript can calculate the row and column lengths.
    • Actions: Actions are output device-specific commands that are required for the implementation of a format. The action printer initialization, for example, can contain a printer command with which the number of rows on a page is defined. There is a set of actions for every format supported by a device type.
