What the Enviroment required for java databases programs?

Hi guys
What the enviroment required for java databases programs?
If I have oracle of version 9i and java 1.4.1 platform
do I need Jdeveloper platform ?

What the enviroment required for java databases programs?What do you mean by "environment"?
f I have oracle of version 9i and java 1.4.1 platformYou just need to download Oracle's 9i JDBC driver (ojdbc14.jar) and put that in your CLASSPATH. Then write JDBC code to connect to Oracle and issue SQL commands.
do I need Jdeveloper platform ?No, JDeveloper is an IDE. Not required.
Why Java 1.4.1? We're up to Java 6 now. You're two major versions of the JDK behind.

What files to download for java and oracle?

Hey
I have read that i have to download and implement some drivers to get oracle to work in
java, but which should i download and where?
Im using Oracle Express 10 and java 1.6
Thanks

Here's the link to get just the drivers
http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/index.html
You could also install the oracle client if you wish to use sql*plus, it has jdbc drivers in folder named jdbc. This is probably a good idea as sql*plus can prove whether your problem is java or oracle.
Installation is simple, you put ojdbc14.jar in the classpath of your compiles and executions. If you are using an IDE, you follow what it provides in its documentation. For Java Studio Enterprise you add them from the "Runtime" window.

What's the best XML for JAVA?

Hi There,
My big question is what should I use for develop a normal XML document, that can:
- contain BASE64 strings
- support UTF-8 add attributes, etc.
I then want to pick this document and:
- do it's parsing (walk trough)
- apply a xsl to this document.
I've made this in C using libxml2 for WIN32/HP-UX, and also in VB using msxml4, now I must make the same document in Java, I see a lot of alternatives but really don't know what to choose...
In these languages I pick a structure that we support (similar to a tree) and serialize it to XML, send it as a string and then rebuild the initial structure with flaws. Each client can have a xsl file to show the information in the way he wants to.
So, I ask your opinion what's the best for JAVA (a fast learning curve is preferable, but speed of processing is very, very important)?
Thanks in advance for all the replies,
Lu�s Pinho

What next for java?

Hi this is a generic question, just for a discussion. However I was thinking, what will come next for java? What would developers want to see in java?
I do not know if this question has been asked before, however it would be intresting to know what other people expect to see in java in the future.
In the last version of j2se we found out new elements like generics, enum, or like the following which I do not know the name of:
public void doSomething(String... strings){
for(String s: strings){
System.out.print(s);
}So now I was windering what you people expect to see next in Java? Do you people think java can still continue to evolve, etc
regards,
sim085

The reason of this post os not to explain me what those things are (I did not relaize I placed two new elements there from the J2se 5.0 ... the cool thing is the varargs ... notice the three dots in the parameter section of thre method) :)
However my post is there to see what other people want to see in Java next :) Thanks for the answer however :D
regards,

Future for Java guys

I seen some of the articles, sap customer are pressuring to release ABAP version of portal instead of java so that, they no need to worry of multiple skilled persons and also they can avoid communication between java and ABAP. If that at is the case what would be the future of java guys who migrated to sap. What do you suggest for Java guys who is going to migrate to sap NetWeaver?

Hi Sreenivasulu,
You don't have anything to worry about. You will not see an ABAP version of the portal. ABAP is great for the business transaction functionality but was not designed to work with the web. That is why a couple of years ago the SAP CEO at Sapphire said that JAVA was going to be an important development tool for developing SAP application.

Just remember that this book is for JC 2.1 not 2.2.1. I have still found this book good for explaining the fundamentals of Java Card development. It just doesn't cover all of the JC 2.2.x API's.

The best H.W and O.S for Java

Hi
I am developing a network monitoring program with too many threads and hundreds of GUI components, I am using my personal PC (windows vista, dualcore cpu 2.2, , 2 GHz RAM, netbeans 6.8)
I know I am using a humble PC but I want to get more advanced/professional H.W and O.S , so my question now is :
what to you use for java (H.W and O.S) as professional and semi-professional solutions? (and if possible the range of prices)
and any suggestions for me to increase the performance of my PC with Java (i think Linux will speed it up but I am not sure which distribution)
Note:
Best Regards.
Anderson.

If you're going to pick Linux, and want to run Sun's/Oracle's Java... Then I'd suggest a distro that is officially supported per:
http://java.sun.com/javase/6/webnotes/install/system-configurations.html
Otherwise pick Solaris (X86/Sparc).

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.

What is necessary for FIM to connect to an AD in another forest?

Hello
I have FIM 2010 R2 installed on fim1.fim1.local working happily provisioning users into fim1.local domain.
Now due to merger we have a second forest additional.local
What is necessary for the existing FIM install to manage users on the additional.local forest as I cannot connect without error?
I can access the additional.local DC from the FIM Server and read the directory. Port 389 is open. I have a domain account on additional.local.
When I try to make an AD MA. I get the error message:
"Failed to search on DN cn=Aggregate,cn=Schema,cn=Configuration,dc=additional,dc=local"
and error code is 0x34.
I tried these values:
Forest: addDC.additional.local
User Name: Administrator
Password: ***
Domain: additional
Where am I going wrong?

Yes I can connect to the external forrest when the DCs have ports 389 88 53 and 464 listening.
However, just one oddity in this FIM. When I push the "Containers" button to select the containers. I must first configure and Add the preferred domain controller (as given on previous dialog form) before I get the list of OUs.
After configuring I can switch it off and all is Ok.
just a comment,just wondering why.

4.6C to ERP6.0 Upgrade - what are the recommendations for Unicode and Java

Hi All,
Forgive such a basic question.
We are just beginning to look at our ERP6.0 upgrade and am unclear whether we should convert to unicode at the same time, and also what are the uses for the Java stack.
Unicode?
We are a single language Latin-1 site so don't need Unicode. However will it become mandatory eventually? Are we better, if we have the opportunity now, just to convert. Also I believe the Java stack is only Unicode. Does ASCII ABAP and Java Unicode complicate things?
Java?
Will we need it? We are proposing a technical upgrade from our 4.6c Javaless environment. Where does Java come in to play in ERP6.0? Doesn't it increase greatly the iSeries HW requirements? (I'm looking at a 2 way 550 at the moment)
Look forward to hearing your views.
Regards
Steve

Hi Stephen,
at the moment, in a latin-1 environment Unicode is for old customers not a requrirement. This might change in 5-10 years ...
Java: No problem at all with ASCII (in latin-1 environments)
=> there is no need for you, but you could go for it. We did several Unicode conversions already and these Latin-1 conversions are pretty easy and simple especially on iSeries, because of the special InPlace Unicode Conversion.
... but this can be done at any time ...
