Devleoper Studio and Workplace for Java application development

1. Can someone please help me know what is netweaver developer studio and developer workplace ?
2. I came across EP master guide that says :
You install an AS Java centrally and the developer workplace on each developer host.
This option is recommended for large development projects with a need for local and central testing. Developers can test their developments locally using the developer workplace. For integration tests, they deploy their changes on the central AS Java.Ûê.® |
You install an AS Java centrally and Developer Studio instances on each developer host.
This option requires fewer hardware resources per developer host. In this landscape scenario you can set up an AS Java in development mode centrally and connect to it from the other hosts in the landscape using the Developer Studio.
How does Java application development take place ? Does this say that we need Developer Studio instances installed on every developer's host (suppose I have 3 developers) or do I need one server setup for Dev Studio and developers using some client program to connect to it ?
I suppose developers create programs on their local pc's, port them to Dev studio for testing and transfer them to EP Dev server ? Is that correct.. ? Thereby, we need CTS+ to promote developments to Qlty and Prod ?

Hi,
Please check-out the following links to understand NWDS, Developer studio and the installation procedure:

MySQL download and setup for java application develop

I would like to setup my computer to be both database and Tomcat web server. Can anybody tell me what to download for MySQL? What are the neccessary steps to setup? Do I need to create DSN ? Thanks,J

Go to http://www.mysql.com/downloads/mysql-4.0.html and download the appropriate file for your platform.
MySQL has VERY thorough documentation. In addition to being online, it will also be packaged with your download. Go to http://www.mysql.com/doc/en/Installing.html for detailed instructions on how to install MySQL on your platform.
You'll also want the latest JDBC Driver. Go to http://www.mysql.com/downloads/api-jdbc-stable.html and download the appropriate file for your platform.

Best book for designing and architecting a java application?

Hi,
Please recommend the best book(s) in the market or on line tutorials which would help me architect and design a java application using SWING.
I have used most of the swing components in many small GUI apps I have developed [JTable, JTree, etc, etc ....] and do not need a beginners books [online tutorials at sun site are good for that]. A book tackling advance topics, which may not concentrate on coding but has very good cases to understand the design [both class level and usuablity] and architecture of the application.
I need to develop an editor for a GUI based language + a code genertor + mapper application [which will run as a application and may use webstart to run from a browser.]
THANKS !

I like "Pure JFC Swing" it's got a well written example for each and every Swing component. When I was learning to use swing each component I came across I could easily look at the example for that component and incorporate it into code for my app. That combined with the Javadoc was all I've ever needed.

HOw to create a Batch file for java application and whats the use of this ?

HI,
How to create a Batch file for java application ?
And whats the use of creating batch file ?
Thanks in advance

First of all, you're OT.
Second, you can find this everywhere in the net.
If you got a manifest declaring main class (an classpath if needed), just create a file named whatever.bat, within same directory of jar file, containing:
javaw -jar ./WhateverTheNameOfYourJarIs.jar %*By the way, assuming a Windows OS, you can just double click the jar file (no batch is needed).
Otherwise use:
javaw -cp listOfJarsAndDirectoriesSeparedBySemiColon country/company/application/package/className %*Where 'country/company/application/package/' just stands for a package path using '/' as separator instead of '.'
Don't specify the .class extension.
Javaw only works on Windows (you asked for batch, I assumed .BAT, no .sh), in Linux please use java.exe (path may be needed, Windows doesn't need it 'cause java's executables are copied to system32 folder in order to be always available, see PATH environment variable if you don't know what I'm talking about) and use ':' as classpath (cp) separator.
The '%***' tail is there in order to pass all parameters, it only works on Windows, refer to your shell docs for other OSs (something like $* may work).
This way you have a command you can call to launch your code (instead of opening NetBeans just to see your app working). You could schedule tasks on it or just call it in any command prompt (hope you know what it is 'cause there have been people in this very same forum with no clue about it, if not just hold the 'Windows button' and press 'R', then type 'cmd' and run it).
Finally add dukes and give 'hem away.
Bye.

Problems between Xcelsius and WebDynpro for Java

How should I do to show Xcelsius in WebDynpro for Java?
How should I transport data between Xcelsius and WebDynpro?
How should I control WebDynpro with Xcelsius?For example,firing plugs in Xcelsius like in WebDynpro to change one view to another.
How should I do to execute a Java method in Xcelsius?For example,scheduling a job on clicking a button in Xcelsius.
Besides these,I also want to know the same problems between other BOE contents and WebDynpro for Java.
Regards,
Abe

Hi Pradeep:
Well that purely depends on the business application (project) your client is proposing. Following are very few factors which will drive for creating web-based applications:
VC: it's a UI modeling tool (non-programming) for creating rapid creation of web-based applications.
WD: its a powered by Java and ABAP with which you can create robust business applications.
If your client is very choosy about rapid application development, reporting, rich user interface, to reduce TCO then VC is the choice. Or if the project contains typical integration with SAP and non-SAP systems, complex business logic development, integration with WCM systems...etc then WDJ is the option.
If youve some sort of custom development with facilitating the Development Infrastructure (NWDI) then WDJ is the only option I could say.
We hope with NW CE 7.1.1(referred by Priyanka Singh) tighter integration between these TWO tools may over come the ambiguity of using them.
Tnx,
MS

How to create the exe files for java application

How to create the exe file for java application?
got any software to do that?
Thanks

In terms of converting java applications into exe files, there are 3 schools of thought:
1) Instead of converting it to an exe, convert it to a jar file. Jar files are more portable than exe files because they can be double-clicked on any operating system. The caveat is that a Java interpreter must be installed on the target computer for the double-clicking to work.
http://developer.java.sun.com/developer/Books/javaprogramming/JAR/
2) Create an exe launcher that, when double-clicked, attempts to find a Java interpreter on the local computer and launches the Java application. The exe file is still double-clickable but whether your java application runs depends on whether a Java interpretor is installed on the target computer.
http://www.sureshotsoftware.com/exej/
http://www.objects.com.au/products/jstart/index.jsp
http://www.duckware.com/products/javatools.html
http://www.ucware.com/jexec/
http://www.rolemaker.dk/nonRoleMaker/javalauncher/
http://www.jelude.cjb.net/
http://thor.prohosting.com/~dfolly/java/index.html
3) Create an exe launcher that bundles a Java interpretor. Same as above but when the exe file is double-clicked, it searches for a Java interpreter and if one is not found, it installs one on the target computer. The caveat is that the exe file would have an overhead of 10 MB in size for the interpreter.
http://www.excelsior-usa.com/jet.html (evaluation version available)
4) Convert the Java application into a native exe file. The caveat is that if you use Swing for your GUI, it won't be converted. Also this option is still somewhat experimental.
Can't think of any free options right now.

Java application development on Mac OSX

Does anyone do Java application development on a Mac? I know that Mac has their own version of Java and I was wondering if there were any difficulties of Java development on a Mac. I'm considering a switch from Windows to Mac and want to evaluate how it will impact my Java development. I currently use Eclipse 3.2. What are the advantages and disadvantages of Java development on a Mac?
Thanks

I'm no Java3d expert but i'm quite sure java is slow on macs, as the java for mac technology is quite bad. Even 2d games with few sprites go slowly on my mac, it's a shame. However this might change as Apple is working quite hard on getting java to work properly, ( mainly because if java becomes popular the macs will lose their incompatibility problem! )

How to access(connect) BI Data in webdynpro for java applications

Hi ,
is there any way to access and display the BI data in portal using webdynpro for java applications like we did in Visual composer.
if not how to integrate the BI data in webdynpro applications ?
Regards,
Govindu

Hi,
Yes there are ways to do it. But may your scenario and the scenario for which I have done may differ.
You can use openhub to get the data in a flat file and then read it into weddynpro through a java service OR
You can use DBlink(which i have done).
Please refer the link below:
[Link|Data from BW to Oracle.;
This I have done in NW04s. Not sure whether a better solution is available in the newer release.
Hope it helps.

Configure CRS2008 to using AD and Kerberos with Java application servers.

Hi All,
I have configure CRS2008 to using AD and Kerberos with Java application servers. Domain Controller is installed on W2K3 Server. In addition, CRS2008 is installed on another W2k3 Server.
I have create service account in domain controller: CMSACC
I have create two user account: CRuser1 and CRuser2
I have create domain group: CRSGroup
After I had run the setspn in domain controller,I got the message at below:
Registered ServicePrincipalNames for CN=CMSACC, OU=TEST, DC=BD, DC=com:
    BOBJCentralMS/BDMGTSRV.BD.com
CMC Setting:
AD Administration Name: BD\administrator
Default AD Domain: BD.com
Add AD Group(Domain\Group): secWinAD:CN=CRSGroup,OU=TEST,D=BD,DC=com
Service principal name:BOBJCentralMS/CMSACCatBD.com
I have create a WINNT folder in root directory.Moreover and save bcsLognin.conf and Krb5.ini at here.
bscLogin.conf:
com.businessobjects.security.jgss.initiate {
com.sun.security.auth.module.Krb5LoginModule required;
krb5.ini:
[libdefaults]
default_realm = BD.com
dns_lookup_kdc = true
dns_lookup_realm = true
[realms]
forwardable = true
BD.com = {
default_domain = BD.com
kdc = BDMGTSRV.BD.com
I have tested the Kerberos,using kinit CMSACCatBD.com password, and got error message at below:
Exception: krb_error 41 Message stream modified (41) Message stream modified
KrbException: Message stream modified (41)
        at sun.security.krb5.KrbKdcRep.check(KrbKdcRep.java:53)

My problem is failed to logon CMC and infoview and got error message at below:
Account Information Not Recognized: Active Directory Authentication failed to log you on. Please contact your system administrator to make sure you are a member of a valid mapped group and try again. If you are not a member of the default domain, enter your user name as UserNameatDNS_DomainName, and then try again.
Actually, I am sucessful to logon Business View manager with CRuser1. However, I fail to logon CMC and infoview and got the above error. Have you any suggestion to solve this problem?
Ken.

if you can logon with client tools then that should be an indication that the service account running the CMS IS working! Good news.
So the problem is likely with the java portion (krb5/bsclogin or java options)
If the files are in c:\winnt\ (if not copy them there) and perform c:\program files\business objects\javasdk\bin\kinit username
then enter and password/enter again
Probably get the same message. To note in your krb5.ini all domain info must be in CAPS (the .com appears to be in lower case)
kinit works with just the krb5.ini, java SDK and AD (removing BO config and the service account from the picture). Once that works if your java options are specified properly you should be able to login to CMC/infoview.
also 1 last point. Add udp_preference_limit = 1 to the krb5 lib defaults section
libdefaults
default_realm = BD.com
dns_lookup_kdc = true
dns_lookup_realm = true
udp_preference_limit = 1

Tim

Invoke Workflow from Web Dynpro for Java Application

I am working on a custom web dynpro for java application and when the user clicks the submit button the SAP standard workflow (WS50000041) should be invoked. Does anyone have experience they can share with me on how to achieve this functionality? It should also be able to attach an adobe form or read data from the form and submit the data as xml.
Thanks,
Ashley

Hi Ashley,
Use following code in RFC to invoke your workflow -
DATA : w_subrc TYPE sy-subrc,
            w_wi_id LIKE swwwihead-wi_id.
CALL FUNCTION 'SAP_WAPI_START_WORKFLOW'
        EXPORTING
          task                      = ' WORKFLOW - WSxxxxxx '
          language                  = sy-langu
          do_commit                 = 'X'
        IMPORTING
          return_code               = w_subrc
          workitem_id               = w_wi_id
        TABLES
          input_container           = it_container
          message_lines             = lv_swr_messag
      COMMIT WORK.
With this code your workflow will get start. But u have to use workflow id in next application also in which your request is getting navigated. In that application you have to take this workflow ID and have to pass again in workflow using - PortalNavigation statements.
After that this workflow will get start to publish in your TaskList (My Task) in Portal. Remeber that your all task should be maintained in workflow table by using SWFVISU transaction.
After that go to Portal and Re-Register your UWL so that your new Workflow ID will get usable in portal.
With this way you would be able to use workflow with Web Dynpro Java using UWL and Workflow.

Roshan Gupta
