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.

Simple for Java guys but not for me,,,
I intend to build an application that will serve as a front end to connect to backend database records. Ideally it will have a UI similar to SQL query tools like TOAD, SQL developer but will be more user friendly so as to avoid making user put complete queries. I have a tomcat server for my work. Please suggest the best way to create such application for a beginner
I guess it will be JSP but need expert opinionsWelcome to the forum!

There is no way at all, let alone a 'best way', for a beginner to create such an application.
Why - that is the first question I would ask. There are already good tools that are free such as sql developer. So why do you think another tool is needed. And why do you think you could do a better job than those well-funded efforts have been able to do?
And why do you think your project won't end up in the trashpile of history like so man other misguided ventures?
Just enter 'sourceforge sql developer' into your favorite search engine and you will get over a half million results and the 'hot' ones on the first page are mostly projects that have been abandoned for many years now.
Any project you embark on, unless it is for your personal enrichment, should fulfill some need that other offerings don't fulfill.
The first step for any serious application project is to create a business plan and a marketing plan that shows the market for such a product and how you plan to achieve a return on investment.
The next step would be to create a requirements document that outlines what functionality the application needs. One part of that would be what databases you want to support: Oracle, DB2, sql server, etc.
You are a long way from needing to know how to actually write such an application until you are near completion with the specs. -
The future of java and what is the most necessary skill to learn
hi, friends,
This is a serious question, so please answer seriously.
1. The future of java
Are there any future for java? What I mean are: are there any jobs for java developer in the future? are there any chances for new java company to survive?
2. What is the most needed skill in so many java technology?
There are so many sections in java technology. so what is the most needed one for one to find a job? what is the most promising section for one to build a company.
Thank your very much!It's a lousy question really.
1) There are very few companies you'd call a 'java company'. There are companies that use java, but they also by and large use C++, DBMS systems, and a whole host of other technologies. If java died, they'd switch to whatever technology killed it. Any decent programmer is flexible enough to learn a new language in a matter of weeks. It's the ability to work with the theory behind the code rather than the knowledge of syntax that's important.
2) It depends entirely on what you're doing. Working with a company where databases are key? Then you need Oracle, or SQL. Working with web technology? Perl, JSP, PHP, stuff like that is what you want. Working in high performance application design? You need C++. Graphics? Take a look at OpenGL or Java3d.
The most promising section to build a company? If there was a straight answer to that 1000 companies would have sprung up already and filled the niche.
Basically, if you want a successful career in programming, don't become a java programmer, become a programmer full stop. If you think you'll be working with java when you retire in 40-odd years you're mistaken. You need to grasp the basic concepts of application and algorithm design, and be quick to learn new technologies and evaluate them against what exists already.
It can take 3 years to go from complete newbie to fluent in a single programming language. It can then take less than 3 days to become fluent in another. -
Is there a market for Java 3d?
Hi, i'm just about to finish college this year and have worked with lots of programming languages during my time in college but found java to be the most interesting... After a while i got into making games in java with the help of the java 3d api. I'm interested in going into this market when i finished colelge but i was just wondering...
Is there a future for java 3d in the games development market?Iron Monkey wrote:

Yuh think ! ? !
That was 75% of the reason. It was waaaaay overpriced.
The ports being on the bottom, where no one could get at them, was another big reason it was not accepted by the public.
I am among those who have been pushing for a desktop system with a mini-like footprint, but imac-like performance -- but I've been advocating this since before the Mini existed.
One idea I put forward in my Mac User Group's newsletter was for a machine just slightly taller than a mini that docks into a cinema display-type monitor. This would allow apple to sell them together for an imac experience, or separately.
Regardless of whether or not they did the docking thing, this is the computer system that could really bring about great Mac acceptance in the corporate world. But of course Apple ignores that space and seem deaf to the needs of industry. -

Best practice for java script placement on a BC page?
Hi guys just a general ask about where the best place for java script is on a BC page.
I just watched the this very good video on optimization http://bcgurus.com/tutorials/how-to-do-website-performance-optimization and in it it says how you should try and load the scripts at the bottom of the page so that it loads quicker.
now I want to do this but with it being a BC site i dont know if certain scripts have to be in the head of the doc. For instance the validate script I have? Does anyone know what I can and cant move from the head?
I was going to do what kiyuco like to practice and add all my scripts to a content holder and then add that to my pages/templates. Will BC like me adding this to the bottom of the page and not the head?
Thanks

Image size and mime type.. non-java guy needs help
Image size, mime type.. non-java guy needs help
Im not at all familiar with java so this is really weird for me to work out. I?ve been doing it all day (and half of yesterday).
Im trying to write a custom clodFusion tag in java that gets the width, height, size and MIME types of a given file. I?ve been trying to get it to work on the command line first. I can get the width and height but cant get the size and the MIME type.
Here is what I got

I've just downloaded your XML Schema for Java software are have been systematically testing it with a relatively simple document. A few bugs:
1. the use="required" attribute of the attribute element doesn't have any effect (doesn't show any error message or throw any exceptions) when the required attribute is omitted.
2. If I declare an element like:
<element name="age">
<simpleType>
<restriction base="positiveInteger">
<maxInclusive value="100"/>
</restriction>
</simpleType>
</element>
Then, if I modify my xml document instance to say:
<age pointless="true">26</age>
This will throw a non-parser exception with a message of null, instead of saying "Attribute 'pointless' not expected", as it does if I redefine the schema declaration as:
<element name="age">
<complexType>
<simpleContent>
<extension base="my:ageType"/>
</simpleContent>
</complexType>
</element>

nullI'm glad someone else has noticed that unique keyref and key don't seem to be working with the Dom Parser. If they don't work WHY ARE THEY (key, keyref, unique) IN THE EXAMPLE'S THAT ARE DOWNLOADED WITH THE SCHEMA PARSER. In report.xsd, a file downloaded with the example, it makes clear usage of unique, key, and key ref. But if you violate the schema definitions in the corresponding file report.xml the parser doesn't complain whatsoever. The only time it barfs is if you change the keyref refer attribute to something other than "pNumKey". It obviously has to work. No bone head would send example files along with their product that didn't work.
So, if anyone at ORACLE or elsewhere has figured out how to use unique, key, or keyref please respond with an explination of how to correctly use them with the parser. Your name will be blessed throughout the ages as a most kind and venerable person. You will be a hallmark, a standard, a shining light for all future generations of what a human being should be! Okay maybe I'm going a little overboard but I'm DESPERATE. With no books or collateral on how this stupid thing works all I can do is hack.

Upgrading Oracle XML Parser for Java v9.0.4 with Oracle Applications 11i
Guys, I applied ATG.PF.H.RUP4. In postinstall steps it is mentioned,Upgrading Oracle XML Parser for Java v9.0.4 with Oracle Applications 11i(doc-271148.1)
which says after applying patch 4038964 do the following--
AUTOCONFIG ENABLED APPLICATIONS ENVIRONMENT
If the Oracle E-Business Suite configuration files are maintained using the AutoConfig infrastructure, proceed with the following:
1. Run the AutoConfig utility.
2. Go to [JAVA_TOP].
3. Run the unzip -l appsborg2.zip | grep 9.0.4 command. If there is a file named as .xdkjava_version_9.0.4.0.0_production, which indicates that XML Parser for Java v9.0.4 is installed correctly as part of appsborg2.zip. Otherwise, run ADAdmin to regenerate the appsborg2.zip file.
4. Restart the application tier server processes such that the new version of Oracle XML Parser for Java will take effect.
but actually the patch is already applied- 4038964. How do i verify if i need to do these steps or not.
The xmlparserv2-904.zip file is already there in wrapper.classpath. of jserv.properties, forms.properties. So i think i dont need to do these steps.unzip -l appsborg2.zip | grep 9.0.4
0 04-18-03 20:10 .xdkjava_version_9.0.4.0.0_production
do i still need to do that step?No, you do not have to since "XML Parser for Java v9.0.4" is already installed as part of appsborg2.zip -
Oracle To End Support for Java 7
No More Free Updates for Java 7 after April 2015
Users must sign long-term support deals or migrate to Java 8 to avoid 'enormous headache and disruption to millions of applications'
Public updates for Java 7 -- including bug and security fixes -- will end this month, a situation that one security advocate says could impact millions of applications.
"As outlined in the Oracle JDK [Java Development Kit] Support Roadmap, after April 2015, Oracle will not post further updates of Java SE [Standard Edition] 7 to its public download sites," Oracle's Java SE Support Roadmap states. "Customers who need continued access to critical bug fixes and security fixes as well as general maintenance for Java SE 7 or older versions can get long-term support through Oracle Java SE Support. The process of migrating users from Java 7 to Java 8 through the auto update feature is expected to take place after the January 2015 CPU release."
[ The art of programming is changing rapidly. We help you navigate what's hot in programming and what's going cold and give insights into the technologies that are changing how developers work. | Keep up with hot topics in app dev with InfoWorld's Application Development newsletter. ]
Oracle released Java SE 7 in July 2011; Java SE 8 was released in March 2014. Java, particularly on the client side, has been beset by security issues in recent years. But Oracle has taken many steps to address the issues and stressed that most of the problems dated back several years, before Oracle took over Java from Sun in 2010.
Still, the impact of Oracle's cessation of public updates could be severe, an official at security firm Waratek, believes. Oracle's "rapid" end-of-life schedule for Java versions is great for innovation and language evolution, Waratek CTO John Matthew Holt said in an emailed statement. "However, there is a dangerous tradeoff; now millions of Java 7 applications will have to defend themselves against code-level vulnerabilities without the benefit of future fixes." Holt advocates either upgrades to Java 8 or use of Java Run-time Application Self Protection (RASP) technologies (Waratek is a RASP vendor).
This week's security update from Oracle, meanwhile, marks the "proverbial 'end of the road' for Java 7 application security, Holt said. "After today, the only version of the Java Platform which will receive public security updates is Java 8. This is huge news, and it is going to cause enormous headache and disruption to millions of application owners around the world."
Contacted Tuesday afternoon for a comment on the end of public updates for Java SE 7, by late evening Oracle had not yet responded.
The April 2015 Critical Patch Update released Tuesday by Oracle provides 98 new fixes for security issues across a wide range of product families, said Eric Maurice in an Oracle blog post. These range from Oracle Database to Oracle Fusion Middleware, Java SE, and MySQL. Fourteen of the security fixes are for Java SE.Java 7 has already been dead for quite a while. While you could still use it for Java apps on your system, Apple blocked its use in browsers long ago. You have to install version 8 if you need Java support for the web.

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.

Oracle database 11g certification for Java developer
Hello,
I'm Java developer, OCPJP 6 ( Oracle Certified Professional, Java Programmer +6+ ) and
I decided to pass exams: 1Z0-051 and 1Z0-052 to get OCA ( Oracle Database +11g+ Administrator Certified Associate ) certificate,
but I need some advice, maybe i should seek other certificate, that would be more valuable for Java developer, than OCA.
Thanks for advice.The answer of whether a particular certification is valuable depends on you, not the tests themselves. The Oracle Certified Master for example is an extremely prestigious certification, and I have considered seeking it at some point in the future to improve my professional credentials. However, the same certification would have absolutely no value to my wife, because she's a homemaker with no interest or intent of ever working with Oracle.
Using an example a little closer to yours, only reversed --- I work as a DBA and PL/SQL developer. On several occasions I have dabbled with Java, and took a couple of classes when I worked for Oracle. I could code in Java if I had to, but wouldn't really be good without a lot of practice. However, I've never really had a sufficient need in my work to dig in and really practice enough to use it. I considered going for the Oracle Java certifications as a means of kick-starting that and getting to the point where it was really a viable option in my development. Ultimately I decided not to because I've been working with Oracle for better than fifteen years and there has never been an occasion where I really felt a need to know Java. If I were to spend a bunch of time improving my Java skills just for the certification, there's no guarantee I would ever use them after that.
Coming back to you -- if you already need SQL and DBA skills in your work, then those certifications should be of value to you immediately. If you think that you might work (or want to work) more with SQL and DBA-level skills in the future, then they should be of value to you in the future. If you won't use the skills now or ever, then the exams do nothing but add a line to your resume (which still has value, but you must determine how much).
