What is Invisible Bean in Java?

For gods sake, go and google it, or ask jeeves.

or try a different forum. Invisible Javabeans relate to the Javabeans spec, and visual programming rather than JSPs. Its basically a bean that doesn't have a graphical representation at runtime, but can be manipulated in a bean development environment

What's the difference between Java SDK and the Enterprise Edition?

What's the difference between Java SDK and the Enterprise Edition? Are they both free?

both r free but they are used in diffrent applications. sdk are used for simple apps that run on your computer while j2e (enterprise edition) are ment for large distributed computer systems that include servers and such. if you don't know the diffrence you probably wont need the the j2e, only the sdk.

JAVA beans and JAVA related services require Oracle client to be installed?

Can you please advice whether an application server that make use of JAVA beans and JAVA related services require Oracle client to be installed? For an example if the solution build based on Java and JBOSS to be used as application server, do we still require oracle client to be installed and configure the tnsnames in order to communicate to database server?

Do I need Java 8 or should i disable it? What happens if i disable it? And what is the difference between Java and Java Runtime?

Do I need Java 8 or should I disable it? What happens if i disable it? And what is the difference between Java and Java Runtime?

There's no difference. They're both runtime plug-ins (they run when an app calls for Java functions).
You only need Java if you either have Java apps on your Mac that won't run without having it installed, or you use trusted web sites that require Java to function (getting fewer and far between). Otherwise, you have no need for it at all.

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 exactly is in "BI java" ?

Hello
We are trying to understand what is included in "BI java" and what will not work without it. I must say that the technical guide or the official presentation are unclear.
As of now, we understand that
- we must run Java in order to use Adobe PDF
- without Java, broadcast, old and new Bex, web reporting, IGS are working
So if i don't need PDF, can i go forward without Java ? In that case, where will i be blocked further in the project ? Can i install it afterwards ?
We would be greatly interested in all your advise on this.
Regards
Fabrice

Hi Fabrice,
Your first area to check questions like this should be the FAQs in the Service Marketplace:
<a href="https://service.sap.com/bifaq">https://service.sap.com/bifaq</a>

<a href="https://forums.sdn.sap.com/thread.jspa?threadID=104198">https://forums.sdn.sap.com/thread.jspa?threadID=104198</a>
and potentielly search the forum with Java, Portal, BEx Web Setup, etc.
You find additional information also in the OSS note #917950 and in the Ramp-Up Knowledge Transfer (RKT) material (if you have problems accessing it, please contact your Ramp-Up Coach).

What is the role of java in the netweaver platform

Hi All
sapnetweaver platform is the integration of the java and abap.then what is the role of java in that netweaver platform
regards
Sunil

Hi Sunil,
        Java makes Sap NetWeaver more powerfull than it was before.
       One of the new additions to the Java functionality of NetWeaver includes the Java Virtual Machine container technology. This will allow standard Java code to run on a framework around the Java Virtual Machine itself. It does this by reducing the number of parallel users per virtual machine. It also improves on the overall memory consumption, the application stability and the number of affected users in the event of a screen freeze, loss of data or the need for re-keying of information.
      The JVM technology also includes several added features designed to assist developers in managing error resolutions. This includes the ability for developers to switch a user process in the production system in or out of debugging mode on the fly allowing for minimum downtime. While also including tracing and monitoring tools for error analysis and hopefully a quick resolution.
         So now, not only does NetWeaver offer support for such standards as HTTP, XML, Web services and of course ABAP, but now it also offers support for Java. All of this adds to SAPs future interoperability with such applications as Microsoft .NET and IBM WebSphere.
         Now that SAP NetWeaver supports Java we will start to see a real positive impact in the marketplace for those who are in search of a cost-effective means to deploy and manage Java applications in their enterprise and small businesses. For companies of all sizes looking for a way to adapt quickly to market changes, respond to unforeseen challenges and to seize new opportunities, SAP NetWeaver is a tool that is worth looking into.

What is web services in Java?

i have searched Google with the word of "web services".I could only find out some general information about web services but not specific.
Could you please explain me briefly?

makpandian wrote:
It describes about web services in common .I want to know what web service is in java platform..
Thanking You.That is a slightly odd question.
There's nothing special about web services in Java against web services in any other language...there are, after all, several web service frameworks in Java, so it's not as if there's even a single answer to it.
Do you understand what a web service is and the associated standards around one? If you do then you should realise that your question doesn't make much sense...unless you're actually asking what ws packages there are around.

What is Markable Interface in JAVA

What is Markable Interface in JAVA need explanation

Markable interface in one which does not contain any
method or member declaration.
Eg: Serializable, Observable etc...terminology aside, I don't think "not containing any methods" is enough to call something a marker interface. is EventListener a marker interface? I don't think so, I think of it as a supertype for all other event listeners in the JDK

What is backing map in Java?

What is backing map in Java?
Thank you

A Backing Map is a map which is used to implement another map.
eg.
- A thread safe map can use a map as a wrapper for a backing map which actually holds the entries.
- a cache usually has a backing map and the cache is also a map, but smarter.

What is going on with Java? How do I disable if needed?

What is going on with Java. Should I be concerned? How do I disable Java on my Mac if needed?

Don't believe anyone who says that Macs are 100% secure and malware free. There have been several notable instances where after hearing this many people have found themselves in the midst of a Mac malware outbreak (MacDefender, DNSChanger, and Flashback, just to name a few).
These attacks have been rare, and with "many people" being around 1 percent of all Mac users, for now this has been far of an issue than on other platforms, but security issues do exist for Macs.
Whether or not this warrants the use of special security software is up to you.
My recommendation is to keep a low-key and free malware scanner on your system, such as iAntivirus, ClamXav, or Sophos Home edition that can be configured to only run on-demand, and then should you feel the need use it to run a scan of your system every now and then. You can also use a reverse firewall like Little Snitch to monitor all outbound connections, which was key for many Mac users who found evidence of the Flashback malware on their systems when that outbreak occurred (just see here for the thread where many detected the suspect behavior: https://discussions.apple.com/thread/3844172).
Since malware is still quite rare on Mac systems, it is debatable as to whether or not security software is necessary, but my stance is if configured as I described then there is very minimal chance it will adversely affect the system. I've configured numerous Macs with anti-malware utilities and have not seen any problems with them, so for the most part there should be neglegable impact (if any). Keep in mind some security tools are more intrusive than others, and include a number of scanning routines that are enabled by default, so each one has its own approaches that will need to be considered. The ones I mentioned here are very light-weight.
The thing that will keep your system safest is (besides "common sense" safe computing practices) to use plugin managers and ad-blockers to prevent Java, Flash, and other plug-ins and scripts from launching automatically.
