Java JDK Versions?
I am installing 11g XE, Weblogic, Forms & Reports, and SQLDesigner for a class and I don't understand why it keep whining about needing obsolete JDK versions. We all know there was a big uproar over Java security issues over the past few years so I don't understand why this software would be complaining when I try to tell it to use the current JDK version. Isn't Java JDK always written to be backward compatible? What about the real installations of this software? Or is the JDK version irrelevant if the JRE is up to date?
Hey guys,
Sorry in advance if my question is a bit uncalled for in this thread.
Somehow I have not managed to get the latest version of Java (1.6.0_31) installed on my MacBook.
According to JavaTester.org I have version 1.6.0_29 which is confirmed by my Java Preferences Panel.
The only 2 versions listed in the panel are 1.6.0_29 (64-bit) and 1.6.0_29 (32-bit)
The webplugin check from firefox states that 'Java Applet Plug-in" is not up to date.
Firefox Add-on Tab says I have 'Java Applet Plug-in' version 14.0.3
Oracle.com says the latest version of Java is Version 7 Update 3
Java.com says the latest version of Java is Version 6 Update 31
Furthermore Java.com says updates will be automatically download through 'Apple Software Update' but it shows no sign of an update.
What's wrong? What is the latest version of both Java JDK and Applet? How can I fix this?

Java JDK versions on Mac OS Lion
I was just looking at the JDK on my Mac with Mac OS X 10.7.3 and it looks like I have different versions of the JDK around.
That's what I have
/Library/Java/JavaVirtualMachines/1.6.0_29-b11-402.jdk
/Library/Java/JavaVirtualMachines/1.6.0_31-b04-411.jdk
/System/Library/java/JavaVirtualMachines/1.6.0.jdk.
Why is that messed up ?
I checked to what I'm pointing and I get that
/usr/bin/java points at /System/Library/Frameworks/JavaVM.framework/Versions/Current/Commands/java
/System/Library/Frameworks/JavaVM.framework/Versions/Current points at /System/Library/Frameworks/JavaVM.framework/Versions/A
Is that ok ? How can I check that I'm really using the most recent version of JDK, in this case /1.6.0_31-b04-411.jdk ? Should I remove redundant JDKs, and if yes what and how ?
Thanks.Hey guys,

Hi,
For implementing Daylight savings, I may need to look at JDK used in my system, The component is SAP_JEE. ( OSS Note - 983147)
Where to look at the version and how to implement it.
System is SAP R/3 4.6B and 4.7
Thanks,
SamIf you want to do it programmatically,
System.getProperty("java.version")
will give you the JDK version information.

Java JDK versions and compilation levels
Hi,
I have a question about differents java versions and the compilance level. As far as I know, if I am developing an application, for example a swing application or a JSF web project, that will be deployed to run in a JVM 1.6, I must compile my code with similar JDK, in this case, I must compile my code with a 1.6 JDK.
But, for example, can I use JDK 1.7 with compilance level 1.6 to run code under 1.6 virtual machine?
Suppose a JSF web project compiled with JDK 1.7 and source level 1.6 can be deployed on a tomcat that run in a 1.6 VM?
If that is correct, I think that I should always get the last JDK version installed in my computer and choose the different compilance level (example 1.4, 1.5, 1.6 or 1.7) to compile my code based on the target JVM, is that correct?
Thanks for your help, regards.kerule wrote:

Correct?Yes, and NO: the problem with what you said is "must be". If you compile with 1.7, but use objects that are backwardly compatible with 1.4, then it will work in 1.4 onward, but if you use features of 1.7 that are not compatible or possibly not available in 1.4, then you will not run in 1.4.
Your statements:
If my project will be executed on a JVM 1.4, I must have installed in my computer a JDK 1.4 and the project must be compiled with 1.4 JDK
If my project will be executed on a JVM 1.6, I must have installed in my computer a JDK 1.6 and the project must be compiled with 1.6 JDK
If my project will be executed on a JVM 1.7, I must have installed in my computer a JDK 1.7 and the project must be compiled with 1.7 JDKare safe, except where/if inconsistancies exist between versions. -
Sentinel SDK support for Java JDK Version 7
According to Oracle:
"Java SE 6 End of Public Updates
After February 2013, Oracle will no longer post updates of Java SE 6 to
its public download sites. Existing Java SE 6 downloads already posted
as of February 2013 will remain accessible in the Java Archive on Oracle
Technology Network. Developers and end-users are encouraged to update to
the most recent Java SE versions. "
When will the Sentinel SDK be compatible with Java 7?
There are security concerns with having out-of-date Java versions on
systems.

I would consider it compatible as of right now. I've used it under
Java 7 reliably for the last 6-9 months, and have not run into any
problems with it to date. If you do run into any problems, feel
welcome to open an issue with NTS and we can look into it.

Using the java jdk version as a conditional
Hi,
I have an method that I only want to occur for jdks over 1.4.2. Is there any easy way (handy API or something) of coding it so I can check what jdk the program is running on and then call or not call a method depending on this jdk being greater then jdk 1.4.2.
Thanks,
Johnno am refactoring an idl to java compiler and need to
take into account changes in the Java Language
Specification between JDK's, for instance certain
things that were legal in early jdks are illegal now
and therefore the compiler should not let java code
be created if it will be illegal for the jdk in use.Could you give an example? The only one that I know of is that pre-1.4, you could use a method named assert(), and post-1.4 you can't. That's going to be a serious problem if it shows up in your IDL, but otherwise not something you need to worry about.
I've found that the more likely case is that I want to use a version-N-specific library method, but still need to compile the code in a pre-version-N environment. In that case, reflection can help: at runtime, determine whether the method is available, and fall back to alternatives if it isn't.
Also, is the JVM version that you're running your compiler on guaranteed to be the same one that runs the generated code? If not, then checking its version isn't going to help. Instead, you'll have to follow the lead of javac, and use "-source" flags on the command line. -

How to check the JDK version of a compiled java file
can anybody tell me how to check the JDK version of a compiled java file ?
Edited by: gbhatia8 on Sep 9, 2010 7:04 AMThe major/minor version of the class file is the way to go.
Also, it's not necessary to write a separate program to get to those. javap prints them out when being passed the -v flag.
Note, however that "JDK version" is not a correct term, as I can create 1.4-compatible class files with a Java 6 JDK (by passing the -target flag to javac). Those won't look any different than .class files written with a 1.4 JDK. -
How to compile a java file with specified jdk version in a program???
hi,
if we want to compile a program in another program with a particular
jdk version as an option, how to do that,plz reply and with example.Hi,
To compile from a program, read this (I've never tried, but I think it
will work):
http://java.sun.com/j2se/1.4.1/docs/api/java/lang/Compiler.html
To get the jre version:
System.getProperty("java.version");
To get the vm version:
System.getProperty("java.vm.version");
Other properties at:

Setting different JDK versions for Different webapp in Tomcat
Hi All,
I have 2 web-applications in Tomcat 5. Now for Java I have j2sdk1.4.2 & j2sdk1.3..
Now One of my application needs j2sdk1.4.2 while other can run only with
j2sdk1.3.. (This is an old project & there are java class package norms - like every class should be in a package to import it now. But earlier it was not strict).
Means this is absoulte for me to run one application with version 1.3 while other with 1.4.
But I can set Java_Home env. varibale only once. How can I tell my each web-application to take thier own jdk version in compiling & running.
Is this allowed in J2EE/Web-Containers.
Please suggest if there is any such setting which makes it possible.
THanks you all in advance...
Manoj :confused:wouldn't matter if you could.
The package enforcement is NOT something from J2SDK 1.4 but from the version of Tomcat used.
Each Tomcat instance will use the same JVM for all webapps running inside it. You'll need a separate Tomcat instance of an older version for the older webapp (or better yet change it around to the new rules). -
How to determine the JDK version required to use a jar?
Hi all.
I am using a hosted server that uses JDK 1.4.2 and I cannot upgrade the VM. I have been finding it extremely difficult to install web applications on this server since I find that after installing the app, the web server complains the bytecode used in the jar is newer than the VM can understand (or it complains that the app uses JEE servlet or JSP methods it cannot find).
To compound the problem, only about 25% of the sites I've visited that provide jars for download mention the minumum JDK version required to use them. (Some do not mention any system requirements at all besides 'requires Java and a Java application server').
Do any of you know of any tools that can analyze a jar and determine the bytecode version it uses?
(Another helpful tool would be one that can determine the minimum JEE APIs required to run a web app..., but that's probably wishful thinking :)).
Thanks for your help.
