Check JDK version
All,
How to check the JDK version the portal server is using?
Is it by verifying it in web server administration console?
Yes, the portal server uses the web server's JVM (JDK).
If you are using Secure Remote Access, the gateway uses a separate JVM.

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. -

JDK Version req for OIM 9.1.0.1 Installation
Hi,
As per Oracle's documentation, we need to use JDK 1_4_2_15 for Oracle Identity Manager 9.1.0.1. Installation. In my machine when I checked Java Version it shows jdk 1.5_0_06. Is there any problem if I go with the default jdk version or I have to change it to 1.4.2_15. Please advise.
Regards,
CCThis is given in docs:
C:\>java -version
java version "1.5.0_06"

Netweaver SR3 on Linux Enterprise 10 - Which JDK Version
Hello experts,
we are facing problems installing Netweaver SR3 (Java) on Linux Enterprise. The problem is that the step Import Java Dump hangs and the installation does not continue. According to other forum threads one problem might be a wrong JDK version. We run Linux on 64 Bit AMD.
Could anyone provide a link for the appropriate JDK version for Linux 64 Bit AMD or further informations (SAP Notes, except 716604)?
Many thanks in advance.

Check note [1172419 - Linux: Supported Java versions on the x86_64 platform|https://service.sap.com/sap/bc/bsp/spn/sapnotes/index2.htm?numm=1172419]
Symptom
You need to install a supported and certified Java VM on Linux x86_64 in order run SAP products based on SAP WebAS Java.
Solution
The currently required version of the IBM JDK 1.4.2 is SR12.

Hi, I'm trying to get a string out of a database via JDBC. When I compile my code with "1.3.0" as target JDK version in the project properties settings, the java.sql.ResultSetMetaData().getColumnType(int column) method says my string is of type OTHER and it comes out as '3003D0022003100...'.
When I compile with "Jdeveloper_1.2.2" as target JDK version, the java.sql.ResultSetMetaData().getColumnType(int column) method returns a type value that does not correspond to any of the 27 types defined in java.sql.Types. The string looks as it should though. Why is this? Does the Oracle compiler or JVM change som settings in the sun.jdbc.odbc.JdbcOdbcDriver that maes the string com out right? How do I do to get the string out as a string with the standars JVM (say when i access it via a JSP)?

nullFredrik,
You don't mention which driver version you're using. I know with 8.1.6, there was a classes12.zip for using JDBC with the JDK 1.2.x, and a classes111.zip for using JDBC with JDK 1.1.8 (I think).
I don't know that they even have a classes13.zip available, so your results may vary if using JDK 1.3. The internal JVM on the server uses JDK 1.2.
I recommend checking the Oracle8i JDBC Developer's Guide and Reference for the version of the database you're connecting to and see info is provided there about compatibility with different versions of the JDK. -
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. -
Hi,
Certification Matrix gives us JDK Version: JDK 1.7.0 SR3+ IV33133 64 Bit
Does anybody know whether this is the exact JDK Version or if we can install anything more than this version?
Thanks very much for your help in advance.Thank you for your suggestion. I can certainly try pointing to a different temp folder, but how much space does it need?
/u00/temp appears to have quite a bit of space available...

Also, I verified TMP, TMPDIR, and TEMP all point to /u00/temp.
And the preinstallation check shows this:
Checking Temp space: must be greater than 1536 MB. Actual 73797 MB Passed
Checking swap space: must be greater than 500 MB. Actual 5951 MB Passed
Checking monitor: must be configured to display at least 256 colors. Actual 16777216 Passed
It might be worth mentioning, as well, that I get the same result, whether I use ...Disk1/runInstall.sh or ...Disk1/install/linux64/runInstall.sh
The file I originally posted came from trying the linux64 installer.
What else can we check/try?
Edited by: user733825 on Mar 28, 2013 6:26 PM
What is it that tells the installer there is an application server running? Is it checking for some WebLogic environment variable I may have incorrectly configured? I have a WebLogic server running, and it is hosting a Forms server and a help server. Why does the installer think there is no Application Server installed?

I have a question that i want to ask for a long time. Let say someone give you a jar file, how do we check which version of JDK it is compile ?
You can get an easy, but approximate, answer by looking in the jar manifest:
$ jar -xf somejar.jar META-INF/MANIFEST.MF
$ cat META-INF/MANIFEST.MF
Manifest-Version: 1.0
Class-Path: someotherjar.jar
Created-By: 1.6.0 (Sun Microsystems Inc.)
Main-Class: Main
The Created-By attribute says which JDK version created the jar file. However, that's not always the same as the version that was used to compile the classes. To get an exact answer, you'd need to look at the class file version number, and you'd have to do it for each class file since they don't all have to be the same. Gory details left as an exercise. Here's a reference to get you started:

hi
how can i determine which jdk version the browser is using from applet.i want to tell the user that if he is using jdk1.4 version than a message appears that this applet can be run on jdk1.3 or less.
ThanksLike I said,I am not a big applet maker but I would
think this would cause a security exceptionI can't tell if this was a reply to my 2nd response, it seemed a little too quick. Anyway, if you didn't catch that, check here:
http://java.sun.com/docs/books/tutorial/applet/practical/properties.html
You can check the version with applets. -
