Is Java a suitable language for raising our robot child?

My wife and I received the devastating news that we can't have children. It's all the years I coded in the
nude, bathed in the radiation of the good old CRT. Anyway, the idea occurred to me that I could
try to build a robot and raise it like as our son. I think I'll be able to sink a PDA into its little styrofoam head,
so I'm going to have to use J2ME -- alas, our son is never going to be a rocket scientist, or render a
Swing GUI.. Anyway, my question: does anyone have any sample code? Hurry, it's urgent!

Tutorial for Java as a language for Portal development!

Hi All,
I am basically a Java, J2EE developer. Now my Employers want me to start working on SAP EP 6.0 SP9. The SAP world is completely new to me.
So
Plz, guide me and provide reference for some good Tutorials or books for Java coding in SAP EP.
Thanx in advance.
Manish

Hi Manish,
start here http://help.sap.com/saphelp_nw04/helpdata/en/19/4554426dd13555e10000000a1550b0/frameset.htm and work through the material.
The books offered by SAPPress for EP development are not recommandable.
SP9 should be upgraded, it's really horrible old and buggy.
Hope it helps
Detlev
PS: Wrong forum, you should have asked within EP Dev.
PPS: Please consider rewarding points for helpful answers on SDN. Thanks in advance!

Java 1.4.2 shows language for system

Hi
Java 1.4.2_01 chooses the language for the system and not for the user.
After installing Java 1.4.2 on my Japanese Windows 2000 professional system all the menus show up in Japanese.
I have chosen English as my local user language and would expect the language to change to that.
The compiler output is also in Japanese.
Any ideas on how to change that back to English like in the version before 1.4.2??
Regards,
Lars

I looks as if someone already enter a bug in the bug parade for this.

Does anyone have some status updated on when this will be fixed?
Are there any other bugs like this one reported?

Limit query for Java Persistence Query Language

Hi,
Anybody know Java Persistence Query Language can support limit querry to limit the number of row return(Like SQL LIMIT clause)?
Thanks

I think the javax.persistence.Query methods setFirstResult and setMaxResults are what you need...

Simple statically typed scripting language for my game?

Hi, I'm looking for a scripting language for my little game. I want make game runnable on both mobile and desktop. I would like to compile scripts to native java for j2me, so they don't suffer from interpreter overhead (possiblity of running an interpreter on j2me is a plus, I can imagine it on high-end devices). On j2se, I would like to have all code to be interpreted (or dynamically compiled, whatever) so user can, for example, download new game content from the internet. Also I would like the language to be simple and cute and it does not have to provide advanced features (like closures or generators). Even classes are optional.
To sum up the requirements:
- statically typed (ideally with smart type inference). This is must in order to allow compilation.
- as simple as possibly (all I want is to define some functions and call them from the game).
- can be compiled to clean Java (byte)code. I mean, it should not wrap every int to Integer for example. Compiled code runs on J2ME.
- can be interpreted (or compiled on demand). Possibility to do this on J2ME is not required but welcome.
- direct importing of native java classes is not required (actually I don't like it, I would like to draw a clean line between scripts and the engine)
- free license (gpl is ok too)
- python-like syntax is a plus :)
Anyone ever heard about such thing? I'm prepared to implement some missing features. Actually I'm prepared to write it all if I don't find suitable starting point.

I fail to see how this is a Java Game Development Issue, or even a Java issue: what you are asking for is a scripting language that you can consequently get the freedom to run on multiple environments through compiling to Java. IMO: not a Java issue at all.

Purchasing additional languages for movies on Apple TV

Hello,
We are a multilingual family, and are trying to promote the use of all our languages to our kids, French, Italian and English. We use the Apple Tv extensively, and I was wondering if there is an option to purchase aditional languages for movies on the Apple TV.
for example we purchase kids movies on the French itunes store and it includes both french and english languages, but not italian. However that same movies is available on the italian itunes store in italian. However since I have already purchased the movies i don't want to buy them all again on the italian itunes store. That would cost too much, but also we would have duplicates of our movies and in seperate itunes store accounts just to be able to watch them in different languages. This would be very inconvenient. In other cases, some movies on the french itunes store only have french as the language, however the english and italian languages are again available in the english and italian itunes store respectively.
The world is becoming ever more international and multilingual, and access to languages should not be so complicated. In fact Apple has always been a pioneer in offering all languages on their Mac OS and iOS, embracing the multilingual spirit.
IT would be extremely useful, if we could add aditional languages to an already purchased movie.
thank you for your help, if you have a solution to my problem.

To have Apple see your request, you should repost it at
http://www.apple.com/feedback
In the meantime, you might want to see whether other stores offer movies with more languages included.

Suitable BAPI for extended withholding tax

we are migrating from classic withholding tax to extended withholding tax for which we are modifying all the programs which were using MRHR (invoice) in the background, since MRHR will be replaced by MIRO in extended withholding tax, in this process when we are trying to modify one program, we could not record MIRO, hence our technical team suggested for use of BAPI functional module, kindly anybody suggest me which is the suitable BAPI for posting of invocie verification.
Thanx in advance.

Hi Krishna,
Please check BAPI_INCOMINGINVOICE_CREATE and let me know.

Why opening from java the rpt search for a JNDI when it's setup for a DNS ?

I downloaded CR for eclipse 2.
All is 'quite' working froma a java app.
i've only a problem with an 'jndi name search error'. I'll try to explain.
In the RPT i use a DSN connection to a sql server into a differente machine. When I open directly the rpt, all is working.
From java code, i'll open the report, but when i try to export to pdf iit tell me about an error 'jndi name search error', with the name of the DSN connection i setup.
Why? Why opening rpt all is working, but opening from code NOT is working ?
What's the difference from two opening methods? Why an .rpt opened from java cannot just open the connection like when opened from cristal report !?
*My question is: why opening from java the rpt search for a JNDI when it's setup for a DNS connection ?! *

The .rpt has been originally created from an ancient version of Cristal report. probably the '8'.
In an italian software called 'Business', the .rpt is populated for printing of invoices and similar docs.
My society is trying to 'integrate' our software with the .rpt used from our customer.
So we want simply open .rpt, add a new logo, set the selection for record and save as pdf.
We so bought Cristal report 2008 (v.12 ), opened the .rpt, saved (so it 's now in a supported version).
The sql server is located at 10.1.2.40, and is a Microsoft Sql Server.
In my development pc I've installed Cr 12. I added a User DSN to point to Sql server at 10.1.2.40, at right DB with username and password. Opening from my development machine the .rpt and 'running' it, it display the data. Ok !
I downloaded CR4 Eclipse 2.
I open report using the unmanaged sdk. (to access it through file system, not via RAS), Ok.
I set selection record. Ok.
I execute .export with 'PDF' for format option and here I get an exception: the JNDI name 'CPR' is not found. Where CPR is the DSN name setup into .rpt from Cristal Report 2008.
So, no, i'm not trying to using the designer from Eclipse, but from the full application. But I must use the rpt at runtime to export some rendered records.
What must I do to do this?
CR4E only supports java based connections, so it is looking for the JDBC/JNDI name and won't look at the DSN's.
How Can i setup at runtime a JDBC / JNDI connection ?
I already have a 'connection' from my code to the sql server, using sqlserver jdbc driver v. 4 from microsoft. And executing query I see the results. So i have right driver, ip, db name, user name and password
But is there a way to simply tell at runtime to my .rpt to use THIS connection? Or a similar connection...
Thanks in advance for help provided to us. (we bought a CR license only for this work...)

What is happening about Java System Identity Synchronization for Windows

I have been playing with "Java System Identity Synchronization for Windows" for a while now. I am about to swich over to is 100%, but I am worried that the latest version is "Windows 1 2004Q3".
Has any one got any ideas about this. The product sort of works, and is much smaller that going for the whole "Java System Identity Management Suite 2005Q4" which is way to big and complicated for our and I think many people.
Don't forget Microsoft have now release its own tools to do this in the latest Windows 2003 SP.

EHP5 - Counntry specific language for users in ESS

Hi Experts
We are using EHP5 and facing problem while enabling country specific language for users in ESS .
Here we have .
u2022     Made language field blank in JCO
u2022     Have maintained country specific language in SU01-Default and in UME
u2022     We have maintained country specific language in browser u2026also .
u2022     We have maintained entry in IMG (SAPDEFAULTESS_ERP2005 )
But itu2019s not working for us either in portal or in NWBC ( we have both connection available to our sandbox ). Other than English it works only for Germen (but not completely few services still appears in English e.g My processes )
Your advice will be greatly appreciated .
Thanks
Aditya

Hi Deepak And Siddharth
Thanks for your reply . I checked language packages in SMLT and here we have status for all languages other than English and German is yellow ( Warning ) Also
for NWBC in role menu only display translation options is available only for English and German and hence we have asked basis team to look into this ..Will keep you posted .
Thanks again

Java as a tool for creating a tutorial?

I am new to Java and have a question regarding its' capabilities. The majority of my work is done using multimedia software (Director, Flash, etc.) but I'd like to use Java for a project (and learn it along the way)...Is it possible to develop an application designed to display text, images, and other content along with interactive tests and examples (with links to and from) to be used as an interactive training program? It would, hopefully, be similiar to the "tutorial's" you find in most software programs.
I'm pretty sure that it is possible (so it's kind of a dumb question) but I also wanted to get any opinions on the level of difficulty and possible suggestions on an approach. (I don't want to rely on a web browser so I'd like to develop an application vs. an applet)
Any advice would be greatly appreciated!
Thank you

Well to be brutally honest, I think you'd be better off sticking with Flash if this is a critical project... it would be a great exercise for learning Java, but would probably take w-a-y-y-y-y-y more effort than doing a similar multimedia presentation in flash.
(I haven't used Director, so can only talk about Flash here) - as you know, Flash is really a very powerful authoring tool that allows the user to do very complex animations very easily, whereas Java is a lower-level programming language that is infinitely more flexible, but comparatively more developer-intensive when it comes to producing user interface stuff. Java might be a viable option if you have to do stuff that flash can't, like very complex interactivity, or pulling info from a database etc (although maybe Flash 5 can even talk to databases now??? I don't know)
You can get tools to help you build Java user interfaces using "drag & drop" methods, and these tools will automatically generate the code for you, but (a) this means you're not really learning java, and (b) flash would still be less labor-intensive (and probably more impressive to your end users)
In summary - I'm not knocking Java or Flash - I love 'em both; it's just that Flash is better suited for certain things, and Java is better suited for others...
PS - nice website, but Portfolios shouldn't have an apostrophe before the "s" ;-)

Java Add-In Installation for EHP4 ERP system

Hello!
we successfully upgraded our SAP ERP system to EHP4 for SAP.
Our system has only ABAP stack.
Question
1) Is it possible to install a Java Add-In instance for the existing EHP4 system?
2) If yes, can this be done on the same Windows server?
Thank you very much!

Specific Requirements
Take the following specific requirements of the new installation process into consideration:
- The previous SAPInst installation service Java Add-In in SAP ERP 6.0/SAP NetWeaver
7.0 was able to add Java usage types such as EPC, or EP, to existing ABAP-only
systems. This was possible only, if you added AS Java at the same time. The option of a
Java Add-In installation is not any longer available as of the enhancement package 4 for
SAP ERP 6.0. Thus, it is not any longer possible, for example, to add EPC and EP
together with AS Java to an ABAP-only system.
[SAP Enhancement Package 4 for SAP ERP 6.0|https://websmp201.sap-ag.de/~sapidb/011000358700000772192007E]
There are many links on SDN discussing ERP EHP 4 dual stack:

Hope this helps.

Java.lang.SecurityException: Authentication for user system denied in realm wl_realm Error.

          Getting this security exception when trying to pull a message from one weblogic
          instance JMS queue, and sending the message (via a MDB) to another machine's JMS
          queue.
          Ex. Here's the scenario.
          Two Windows2000Server machines,
          one at ip ... xxx.xxx.x.16,
          second machine at ... xxx.xxx.x.17.
          MDB pulls message off of a JMS queue on 16. MDB sends the message to .17 box.
          ON the .17 machine (the receiver) I get the following exception
          weblogic.transaction.internal.CoordinatorImpl@31406b>

          The messages appear to show up on the destination machine, but are these error
          messages valid, or just bogus?
          Thanks,
          Eric.


Why is that? Your suggestion worked but I don't understand why.
          When our MDB on machineA did the JNDI lookup to MachineB we set the
          credentials to a valid user/password on MachineB.
          My speculation: Since the MDB on machineA is already in a transaction
          any other JNDI calls use the credentials for the MDB's transactions,
          ignoring any other credentials we might try to set explicitly. If my
          speculation is correct then that would explain by the passwords for the
          user "system" would have to be the same between servers.
          Is there a good place to read up on this?
          Thanks

If you are using JNDI authentication, make sure you close the context before
you get another context.
In WLS, stack of authenticated users will be maintained per thread. Now when
user is authenticated, it will be pushed into the stack. When you close the
context it will be popped out. In your case it seems like somehow test1 user's
idenitity is set on the thread which is calling the EJB on server2.
use weblogic.security.acl.Security.getCurrentUser() to get the current
user associated with the thread.
I hope this helps.
