Java dc use another java dc with java.lang.NoClassDefFoundError

Dear All:
I've created 2 java dc.
I assinged the second dc as a used dc for the first dc.
I've created a web dynpro dc and add the first dc as used dc.
I can build those three dc without any error, but when I deploy to server and run I got an exception "java.lang.NoClassDefFoundError"
Is there anyone know how to fix it.
thanks in advance.
Allen.

Hi Allen,
I believe the following link will help you create two public parts (for Compile Time and for Runtime) of the wrapper DC and then include the Public Parts in the Used DCs of the Final Development Component.
http://help.sap.com/saphelp_nw70/helpdata/en/42/43973fade73c17e10000000a114084/frameset.htm
Without adding the Public Parts, your final DC to consume the Java Library would not show any Compile Time Error but would throw Class Definition Not Found Exception even though you deploy the wrapper DC on the Server. This should solve your problem. For any clarification you can always come back to me.

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:

Add AD Group(Domain\Group): secWinAD:CN=CRSGroup,OU=TEST,D=BD,DC=com

I have create a WINNT folder in root directory.Moreover and save bcsLognin.conf and Krb5.ini at here.
bscLogin.conf:

I have tested the Kerberos,using kinit CMSACCatBD.com password, and got error message at below:

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

Using GAP math software with Java 1.4, possible?

Hello all,
i work at a tech university and a Prof. has the following question:
Some of his students want to use a free math software package called GAP with their diploma work. Question is: Can they use the GAP package with Java 1.4 Math Class and how does one interact between using GAP and Java 1.4?
If anyone can help, i would be much obliged.
Thank you.
Raymund

There does not seem to be any such capability, based on the articles in the GAP forum. You might want to look at this article which mentions a means of using Maple and GAP from Java programs.

Use DB Sequence/Trigger with Java types

The documentation(Fusion Dev Guide 4.10.10) covers using triggers to assign DB primary keys. This does not seem to apply when using java types.
I have a create button on a master level page which should take the user to a detail level page to fill in the item properties.
How can I use the DBSequence type with java typed variables?

This chapter tess you that you can use the trigger assigned PK only for the db sequence type.
Still you can use a db sequence to get a unique number and assign it (after converting it to the right type) to a java type. This you have to do yourself.
this is the javadoc for the class [http://download.oracle.com/docs/cd/E15051_01/apirefs.1111/e10653/oracle/jbo/client/remote/SequenceImpl.html|http://download.oracle.com/docs/cd/E15051_01/apirefs.1111/e10653/oracle/jbo/client/remote/SequenceImpl.html]

Hello i try to use another SIM card with my iphone 4s now it said i need to unlock the phone with my Sim carrier

Hello i try to use another SIM card with my iphone 4s now it said i need to unlock the phone with my Sim carrier ... here is what it says below
The SIM card inserted in this iPhone does not appear to be supported.
The SIM card that you currently have installed in this iPhone is from a carrier that is not supported under the activation policy that is currently assigned by the activation server. This is not a hardware issue with the iPhone. Please insert another SIM card from a supported carrier or request that this iPhone be unlocked by your carrier. Please contact Apple for more information.

So.. You need to contact the carrier for the iPhone's original sim card, and request they unlock it. The carrier is the only one that can unlock the sim of the iPhone.

How to upgrade Forms 11gR2 to use JAVA 7 after it was installed with JAVA 6

I recently installed Forms 11gR2 on a development server. We are trying to have the latest versions of everything to migrate from Forms 10g and assure we have support for the next few years.
Our platform has the following software configuration:
Solaris 10 (Update 19) SPARC 64 bits
Weblogic 11g (10.3.6) that was installed with Java JDK 1.6.0_38
Forms 11g R2 (11.1.2.1) that was also installed with
Java JDK 1.6.0_38
I tried to install Weblogic and Forms using the latest Java 7 JDK (1.7.0_25) but I got an error in the final steps of Forms setup, when I was configuring the domain. I searched online and found a couple of tips but nothing worked. The installation was stuck at the
Creating Weblogic Domain step. So I decided to try the installation process with the Java 6 JDK that we are using right now for Forms 10g, and it worked perfectly. I have now two options but I don't know which one might be the better path:
Uninstall Weblogic and Forms 11g completely, and try to re-install them again with Java 7, trying to fix the error that I got at the end of the configuration process.
Try to upgrade the current Forms 11g installation from Java 6 to Java 7. I found a blog that might suggest it is possible, but I don't know if it may cause additional issues along the road. http://pitss.com/us/2013/02/20/how-to-use-java-7-with-oracle-forms-11g-in-an-oracle-supported-environment/
Thanks in advance for any suggestions you might have, or if any of you has experience installing Forms 11gR2 with Java 7 it might be great to know how to fix this error. It might be worth mentioning that when I installed Forms and Weblogic with Java 6 I used exactly the same values, ports, options and paths. The error appears like this in the installation logs and the process hangs there:

Well if I got it to work with java 6 I'd leave it alone, to say the least. The elephant in the room is the certification matrix.
http://www.oracle.com/technetwork/developer-tools/forms/overview/index.html
there's 2 issues, what jdk does forms on the server want? Bigger question, what JRE is acceptable on the client?
You would surely want the jre to be 7 on the client. Regarding the jdk on the server, you could leave it as is IMHO.
Note that there was a patch to 11gr2. In conclusion, be sure to check the cert matrix regarding what is certified for the jdk for the server.
I think the matrices are saying that if you have forms 11.1.2.1.0 that you can use the jdk 7. but like I said the big issue is what can the client use?
As I read the matrix I think it is saying you have to have 11.1.2.1.0 to use the jre 7 on the client.
So I would say if you have 11.1.2.1.0 on the server you are good because it's not a problem to have the jdk 6 on the server, if not you have to apply the patch in order to enable the jre 7 on the client.

Using SQL reporting services with java

how can i use Microsoft SQL Server reporting services with java? The idea is that we create the reports using Microsoft SQL Server reporting services. Then we have our web application where user will select one of those report, pass 0 or more arguments and then we will show the report.

nobody is using Microsoft SQL Server reporting
services with java?Found this in 0.01 seconds with Google http://www.javaworld.com/javaworld/jw-01-2005/jw-0110-sqlrs.html

Is using Excel through Automation with Java possible ?

Hi, I'm currently a Visual Basic developper thinking of moving to a java based RAD technology.
For a couple projects, I need to generate Excel Spreadsheets and present them to the user. I usually do this in VB by using the COM object provided by Excel, instancing it and using the Range([cellname]).value property to write data in the sheet.
Is their any way to do a similar thing in Java, or does this level of comfort come solely by using a Microsoft developpement product (thus more integrated with office) ?
Thanks in advance.

1. Writing java functions in MS Visual J++ 6.0, instead of in MS VB, and then compiling as a COM function has been the only way I've been able to mix the convenience of spreadsheet IO (alas, still in Excel) with the powerful functions we can write in Java.
2. It's ironic java programmers must still build IO interfaces in their IDEs every time they want to write & use a new java function, while MS has made user-written VB functions available to all Excel users (even to MS Word users). Last time I looked, the Star Office speadsheet only allows writing functions in ersatz VB (Sun Basic) instead of in Java.
3. To Sun: Please make java available to the masses by giving us a spreadsheet that runs user-written java functions. The spreadsheet is the most powerful programming paradigm around. Remember when Lotus made a zillion $? You can make more money from Gates's vision than by imitating his products.

How to use the Rc4DLL.dll with java (jre1.4 )

I am not able to use Rc4DLL.dll with java, there are some characters (encrypted using Rc4DLL.dll) that java is not able to identify. So while decrypting in java using Rc4DLL I am not getting the desired output (as some character java tries to decrypt are not supported with java). Could some one give a solution of using Rc4DLL with java jre 1.4

RC4 cipher is supported by 1.4.
And surely you can turn a link to the 1.5.0 JCE Reference Guide into a link to the 1.4.2 Reference Guide? I did. Took me 5 seconds to check that. As opposed to wasting a day and a half in forums like you just did.

SQLEception using Complex SQL Query with Java Studio Creator2 Build(060120)

I am evaluating Java Studio Creator2 for a WEB base application project that will be making SQL queries to an Oracle Database but I have stumble into a problem using complex SQL queries.
I am getting an SQLException "org.apache.jasper.JasperException: java.lang.RuntimeException: java.sql.SQLException: [sunm][Oracle JDBC Driver][Oracle]ORA-00923: FROM keyword not found where expected". I looks like it cut my sql.
The SQL that I am trying to execute is
Select part_name
from table1, table2
where table1.part_nbr = table2.part_nbr
and table2.row_add_dt = (select max(table3.row_add_dt)
from table3
where table3.ser_part_id =table2.ser_part_id)
This is a valid query that it is using 2 different selects to get a part number.
If posible, point me to the best solution were I will be able to make complex SQL queries like the one above and bigger.
Is there any way that I can read an SQL query file instead of inserting the SQL query string into the setCommand()?

I have read that document looking for some anwsers on how to make this kind of query. If I try the query that I have above in the query editor ,the query editor will cut off from the last select that is between ().
I beleave, there is a work around using the inner joint or outter join command. I will try them to see If I get the corrent result. If not, then I have to keep on asking for possible solutions.
Anyway, someone in the Creator Team should take a note in adding something like a special criteria in the Add Query Criteria Box for cases like the one I have. The special criteria will be like using another select/from/where to get some result that will be compare.
Girish, Are you in the Sun Creator Team?

Using Command Line Arguments with JAVA

Hi,
we are using an app called ImageMagick to scale and modify images before they are uploaded to a webserver.
ImageMagick is called from our Objectiv-C app via
command line.
is there a way to this in Java?
Regards
Eckbert

So, ur question is not developing a Java application that
will do the 'image conversion'; but, your message
conveys that u want to know how to invoke a Java program built by 'imagemagick' that takes command line arguments?
Am I right?
If that's the case, u must look into the documentation
given along with the download'ed piece of software
for identifying the 'starting point of the program'. i.e., the
class that contains the 'main' method! And after you
identify that class [Eg. ImageMagickStart] then you'll
have to invoke as follows:
[you must have Java installed in ur system!]
c:>java ImageMagickStart
If the program was written intelligently it must print all
the command-line arguments required by the above
program by executing the above command, and from that
you can identify!

How to use a progress bar with java mail?

Hi, i'm new here.
I want if someone can recommend me how to show a progress bar with java mail.
Because, i send a message but the screen freeze, and the progress bar never appear, after the send progress finish.
Thanks

So why would the code we post be any different than the code in the tutorial? Why do you think our code would be easier to understand? The tutorial contains explanations about the code.
Did you download the code and execute it? Did it work? Then customize the code to suit your situation. We can't give you the code because we don't know exactly what you are attempting to do. We don't know how you have changed to demo code so that it no longer works. Its up to you to compare your code with the demo code to see what the difference is.

Invoking "java myClass" using Runtime.Exec from a Java Stored Procedure

Hi All,
This is regarding the use of Runtime.getRunTime().exec, from a java programme (a Java Stored Procedure), to invoke another Java Class in command prompt.
I have read many threads here where people have been successuful in invoking OS calls, like any .exe file or batch file etc, from withing Java using the Runtime object.
Even i have tried a sample java programme from where i can invoke notepad.exe.
But i want to invoke another command prompt and run a java class, basically in this format:
{"cmd.exe","java myClass"}.
When i run my java programme (in command prompt), it doesnt invoke another command prompt...it just stays hanging.
When i run the java programme from my IDE, VisualCafe, it does open up a command prompt, but doesnt get the second command "java myCLass".
Infact on the title of the command prompt (the blue frame), shows the path of the java.exe of the Visual Cafe.
and anyway, it doesnt run my java class, that i have specified inside the programme.
Even if i try to run a JAR file, it still doesnt do anything.
(the JAR file other wise runs fine when i manually invoke it from the command prompt).
Well, my question is, actually i want to do this from a Java Stored Procedure inside oracle 8.1.7.
My feeling is, since the Java Stored Procedure wont be running from the command prompt (i will be actually invoking it through a Oracle trigger), it may be able to invoke the command prompt and run the java class i want. and that java class has to run with the SUn's Java, not Oracle JAva.
Does any one have any idea about it?
Has anyone ever invoked a java class or JAR file in command prompt from another Java Programme?
YOur help will be highly appreciated.
(P:S- Right now, my database is being upgraded, so i havent actually been able to create a Java Stored procedure and test it. But i have tested from a normal java programme running in command prompt and also from Visual Cafe).
Thanks in advance.

Hello Hari,
Thanks for your quick reply.
Can you please elaborate a little more on exactly how you did? may be just copy an dpaste taht part of teh code here?
Thanks a lot in advance.

How to use another SIM card with my AT&T Iphone

I have to go in france and use a French office' sim card from another provider than AT&T. But here, I've got all my professional, and private, mail box and conatct on it.
How have I to do in order to use this other sim card in my Iphone? I don't want to buy another cell phone for only few weeks in year !
When I was in france my provider was agree to unlock my old iphone before leaving the country. that's why that was easy for me to use it in US with an AT&T sim card. But now, they change my oldest 3g with a new one, it is impossible for me to have the same situation ...
and I'm a AT&T customer since more two years ...

There is no way to use a phone locked to AT&T with another provider. AT&T does not unlock iPhones for anyone. Ever..
