Support of Java EE 6 in NW AS Java ?
Hello Expert,
Current release of NW AS Java did not provide full of Java EE 6; Is there a planned release/version of
NW AS Java which will ?
Any advice is appreciated !
Ying-Jie Chen
Hi,
(late update)
I guess the Java Version - the version of the Java Virtual Machine (JVM) - is mixed up with the Java EE spec version.
NW 7.3 is still on Java EE 5 from 2006. This is still valid on Jan 2nd, 2014. SAP is the only Java EE container I know that did not upgrade to Java EE 6 yet (Java EE 6 spec final release is from Dec 2009). The other known Java EE Application Servers were upgraded to Java EE 6 years ago and most are on the way to Java EE 7.
The JVM below is Java 6 (not yet Java 7 - unlike Oracle Java 6, SAP JVM 6 is still supported because SAP did not yet upgrade to JVM 7).
Regards
Rolf

My web page uses a Java Applet to allow my visitors to replay chess games; the Chess Viewer Deluxe applet was written by Nikolai Pilafov some time ago and has been working properly for some time (until recently). I don't monitor this part of my site regularly so I am not sure when it began to fail. On his web site [http://chesstuff.blogspot.com/2008/11/chess-viewer-deluxe.html] he has a link to check LiveConnect object functionality (which fails for OBJECT tags). His recommendation is to "seek platform specific support which might be available from the JRE developers for your platform".
I have been getting java.lang.ClassNotFoundException: ZeroApplet.class and java.lang.ClassNotFoundException: JavaToJS.class crashes with JRE version 1.6.0_26-b03-384-10M3425 VM executing a Java Applet. Until I checked the LiveConnect object functionality, I was unable to identify the source of the console error messages. This does seem to be the smoking gun.
Is Apple aware of this problem? Are these classes no longer supported? Has anyone else had this problem? You can attempt to recreate the problem locally by going to my web page: http://donsmallidge.com/DonSmallidgeChess.html
Thanks in advance for any help you can provide!

Dynamic Java bean classes for XSD using JAVA (not any external batch or sh)
Hi,
How can we generate dynamic Java bean classes for XSD (dynamically support All XSD at runtime)?
Note: - Through java code via only needs to generate this process. (Not using any xjc.bat or xjc.sh from JAXB).
ThanksMuthu wrote:

Pretty sure you can't. Probably can do a lot of them with years of work.
And can probably can do a resonable subset suitable for the business at hand with only a moderate effort.
Note: - Through java code via only needs to generate this process. (Not using any xjc.bat or xjc.sh from JAXB).The Sun jdk, not jre, comes with the java compiler as part of it. You can create in memory class (I believe in memory) based on java code you create.
I believe BCEL alllows the same thing (in memory) but you start with byte codes.
You could just create a dynamic meta data solution as well, via maps and generic methods. Not as fast though. -

the database is up and running, the Oracle Listener is also working well.
Any idea??
Thanks so much in advance!
Best Regards,
GerdHi Sunny, hi Markus!
many thanks for your hints!
I've just solved the problem. The problem was, our Listener was not configured correctly.
I've adjusted the listener.ora, tnsnames.ora to the correct hostname - cause, we had a hostname-switch last month and I had forgotten to adapt the Listener...
now the Listener is running as well:

Bug on native code of OJVM java.util.zip.CRC32.updateBytes(CRC32.java)

Basically it takes the content from a BLOB column of the wpg_document table, unzip it using java.util.zip package, look for the file content.xml and parse it using Oracle XML toolkit.
Using an open source utility which replace java.util.package (http://jazzlib.sourceforge.net/) it works perfect because is a pure java application.
Best regards, Marcelo.
PD: I am using Oracle 9.2.0.2 on Linux.The cause of errors was a dying Westen Digital drive, specially the 48G partition reserved only for $ORACLE_BASE (/dev/sdb3 mounted on /opt/oracle).
A simple quick scan of unmounted partition (badblocks -v /dev/sdb3) reported more than thousand new bad blocks (compared to the last scan six months ago). Although I strongly believe, specially in the case of WDC drives, that the best utility to "repair" bad blocks is the one that opens a window and prints the message: "Go to the nearest shop and buy a new drive", I was very curious to prove my suspicion just on this drive. After zero-filling the partition with dd, then formatting it (mke2fs -cc) and mounting again, the 11g installation and database creation (on the same partition) successfully completed, performing fast and smoothly. To make sure it was not a casual event, I repeated the installation once again with full success. The database itself is working fine (by now). Well, the whole procedure took me more than four hours, but I'm pretty satisfied. I learned once again - stay away from Western Digital. As Oracle cannot rely on dying drive, my friend is going tomorrow to spend a 150+ euro on two 250G Seagate Barracudas and replace both WDC drives, even though the first drive seems to be healthy.
In general there is no difference between loading correct data from good disk into bad memory and loading the incorrect data from dying disk into good memory. In both cases the pattern is damaged. For everyone who runs into the problem similar to this, and the cause cannot be easily determined, the rule of thumb must be:
1. test memory and, if it shows any error, check sockets and test memory modules individually
2. check disks for bad blocks regardless of the result of memory testing
Therefore I consider your answer being generally correct.

can someone pls help me with java on my macbook pro because after i download the mountain lion java has died and i need java to see streaming quotes from stock market
Java is no longer included in Mac OS X by default. If you want Java, you will have to install it.
However, note that you should think twice before installing Java for such a trivial need as looking at stock market quotes. There are other ways to get that information that don't involve Java, and using Java in your web browser is a HUGE security risk right now. Java has been vulnerable to attack almost constantly for the last year, and has become a very popular, frequently used method for getting malware installed via "drive-by downloads." You really, truly don't want to be using it. See:
Java is vulnerable… Again?!

Attempting to install the "missing plug-in" using the Firefox prompts results in Java 7 Update 10 being installed, re-installing it is successful and does not resolve the issue, Firefox 18 refuses to allow/display java content even with the proper updated version of Java installed.
This problem ONLY occurred immediately following this mornings update to Firefox 18.0.Context:
Yesterday: Java working fine.
This morning: Update to Firefox 18.0
Java will not work, not at all even with Java 7 Update 10 installed, not even the "verify java version" applet at http://www.java.com/en/download/installed.jsp will display.
When attempting to view/display any java content the "missing plug-in" error bar at the top of the page displays and attempting to install the required plug-in via that method does not resolve the issue even though the correct version of Java is installed and the plug-in checker verified it was "up-to-date". -

This is OK if you are writing a console program and the user can input the name in a command line prompt. If you are writing a server side program, there is no console, you need to write your own CallbackHandler to provide username. -
How to start to work on MDM JAVA API by using webdynpro for java
Hi all
I have basic idea on MDM business package thru portal by using standard iViews.
now i am planning to work on MDM JAVA APIs by using Webdynpro for Java as UI.
1) can you please share the required documents on the same. how to start working on this by using MDM JAVA APIs in webdynpro for java
2) what are the JARs files are required and how to integrate those jar files into webdynpro for java application.
3) is there any SDN help on MDM JAVA API with webdynpro for java? . can you please send the link on the same.
4) can you please help by providing sample code on how to use JAVA APIs for retrieving,deleting,inserting and Updating the data in the database.
if anybody helps on the same then it is the great help to me.
points are always rewardable...
Regards
Suresh babuHi Suresh,
You can have the MDM JAVA API javadocs from the link
http://help.sap.com/javadocs/MDM/SP06P2/index.html
There you can see a package named com.sap.mdm.examples.The classes in it contains some examples using which you can start understanding the code.
You need to have MDM JAR files for it. And these JAR files to be used at build time can be added to the project thru :-
Right click on project-> properties->Java Build Path - > Add external JARs
At run time you can add them the reference in
Right click on project-> properties->web dynpro references->library reference.
Thanks

What are the limitations of Java,what cannot be done with Java?
Hello.I want to ask, is there anything which cannot be done with Java related to computer programming ,does Java have limitations?
BIJ001 wrote:
You need a JVM to run Java applications.Usually yes but nothing prevents you from writing a compiler to compile Java sources right into native code.@Everyone: Sorry folks, I meant to say "Never say unequivocally that something cannot be done. Time will more than likely prove you wrong."... which I think you all got the gist off, despite what I actually said.
@BIJ: Hmmm yep, so that sort-of brings writing a device driver in the Java language into the realms of practicality, except you'd still have to work-around the fact that Java is by design a device/OS idependant language, so one suspects that you'd probably end-up using to JNI to call a large and complex library of assembler (or something) functions, which actually do the work... hence you'd probably be better of in assembler, C, or indeed any "native" language, or combination thereof.
Java excels at writing "large and complex business systems". Java pretty much sucks at writing "low-level CS stuff", which C (and assembler) both excel at... Hence some knowledge of both helps you pick the tool for the task, and create "complementary" layers of abstraction in your application, which (the theory goes) make it robust and flexible.
I do think that it's interesting that Java excels in exactly the places where C is/was "undercooked".... I do sometimes wonder if that was by design; like the language designers intended them to be complementary tools or something.

Java.lang.UnsatisfiedLinkError: no ocijdbc8 in java.library.path
hi,
i am trying to connect to an oracle 8.1.7 database from my application running on tomcat 4.0.3 / jdk1.4 /windows nt.
using the thin jdbc-driver (classes12.zip) everything works fine.
when i try using the oci8-driver, i get an error-message saying:
java.lang.UnsatisfiedLinkError: no ocijdbc8 in java.library.path
i have the oracle-client installed on my machine.
the ocijdbc8.dll can be found in D:\server\oracla81\bin
the environment-variables PATH, CLASSPATH, LD_LIBRARY_PATH (i'm not sure if this has any meaning on nt) all point to this directory.
i start tomcat using the following option: -Djava.library.path="D:\server\oracla81\bin"
my application can see this variable:
System.out.println("java.library.path: "+System.getProperty("java.library.path"));
prints out the correct value.
then i try to load the library by myself:
try {
System.loadLibrary("ocijdbc8");
System.out.println("Successfully Loaded");
} catch(Exception e) {
System.out.println("LD_LIBRARY_PATH is not properly set");
e.printStackTrace();
everything works fine! the library is loaded!
finally i try to connect to the database and the application throws the mentioned exception:
lang.UnsatisfiedLinkError: no ocijdbc8 in java.library.path

any help would be appreciated.
thanx in advance,

[email protected]It is probably JDK 1.4 that causes the problem. I was able to get strange errors with that version of the JDK with code that worked fine using 1.31.

I also read that you can run java headless to avoid the dependencies to X. Now is there a way to run tomcat (or add variables to tomcat's startup.sh) to avoid having these dependencies?
Thanks for your help,

Any ideas for further troubleshooting? Thanks, - DaveThe oci library must be in the shared library path of the platform. Simple as that.
Do you have that library(ocijdbc10) installed? On platforms besides MAC a client install of the Oracle GUI allows for it.
