Utility to check Java source JVM version compliance
Does anyone know of any utilities that can check Java source for compliance against various JVM versions (other than an appropriate compiler!).
So, for example, we're developing using an IDE that only works against 1.4 and later, but must develop to a rather old JVM. At the moment we need to know to avoid certain language constructs, etc. It would be nice to verify that we are compliant before delivering the system for test.
why other than a compiler? no better test than compiling! later compilers can still compile for an earlier JVM, if you wish
I'd trust the compiler more than I would some third-party checking application

Simple JSP Code to check JVM version
Does any know a simple code to check the JVM version?
you can try to use the java.lang.Runtime,and then execute some local system call.
But I don't know about the exact call
Runtime runtime=Runtime.getRuntime();
runtime.exec("*** "); -
How to check Java Card CC EAL version?
Hi friends..
I want to know, how to check the CC EAL version of our Java Card?..
Roughly, What is the different between Java Card CC EAL4 and Java Card CC EAL5?
Are both of them differentiated by Cryptography supported by each chip?..
I mean, whether or not Java Card CC EAL 4 support only Symmetric Key, while Java Card CC EAL 5 support both Symmetric and Asymmetric Key?..
Please correct me if i'm wrong.
ThanksHi,
I want to know, how to check the CC EAL version of our Java Card?..Check out following website. All CC certified products are listed here. Assurance level is also mentioned with the product description.

CC assurance level has nothing to do with support of cryptographic feature. Check out following link for more more information.

Hi,
In our xMII 11.5 server system, I found that java JVM version is 1.4.2_07. In my client side JVM version is 1.5.0_11. Will it be a problem?
-RajHi Govind,
This depends on the version of xMII you are running. From SR3 onwards (11.5.3), I believe the xMII server needs to have JSDK 1.4.2_13 or newer and officially supports JRE 1.5.0_09 or newer on client machines.
Maybe you can post the service release your are on and you can get a more accurate answe on this forum...

Java Webstart application problem with TLS certificate revocation checks (Java 1.7.0_76)
We have a problem with our Java Web Start Application regarding the TLS certificate revocation check:
The application is running on a server within a wide area network which is separated from the internet.
The application users have access to the WAN, and also access to the internet over some corporate proxy/firewall.
The user has to enter, for example "https://my-site.de/myapp/ma.jnlp" within a webbrowser or could also call "javaws https://my-site.de/myapp/ma.jnlp" to start the application client.
The webserver has a certificate from a trusted certificate authority. This certificate seems to be ok, the browser is even configured to perform OCSP status check.
The application files are signed with a certificate from another trusted certificate authority. This certificate seems also to be ok. Regarding this certificate there
are no problems with certificate revocation checks.
The problem is, while starting the application client there is a message box which tell us something like "the connection to this website ist not trustworthy",
"Website: https://my-site.de:80", and something about an invalid certificate, meaning the webserver certificate.
Obviously the jvm runtime, which is executed on the users workstation, tries to perform a revocation check for the webservers certificate, but this fails because
it cannot fetch the certificate under https://my-site.de:80.
The application will execute without further problems after that message but the users are very concerned about the "invalid" certificate, so here are my questions:
- Why is the application trying to get the webserver certificate over Port 80. Our application developers told me, there is no corresponding statement. Calling this address
has to fail while "https://my-site.de:443" or "https://my-site.de" would not have a problem.
- Is there a way to make the application go on without performing a tls revocation check? I mean, by adjusting the application sourcecode and not by configuring the users Java Control Panel.
While disabling the TLS Certificate Revocation check in the Java Control Panel, the Webstart Application executes without a warning message, but this is not a workable solution for
our users.
It would be great if someone can help me with a hint so i can send our developers into the right direction;-)
Many thanks!
This is a part from a java console output after calling "javaws -verbose https://my-site.de/myapp/"

Check java on users PC and give message
The following code has been written with Java 1.4 and works great, but if a user has Java 1.3 they get an error message and if a user has Java 1.2 nothing happens at all. Is there a way to check if the user is using a version older than 1.4 and if so pop up a message telling them they need to download a newer version of Java?

How to read the Java source code (in Netbeans)
I use OS X10.5.5, NetBeans 6.1 and JSE 6 on a 64 bit mac.
When I downloaded NB6.1 it had JSE 5 as it's default (and only) java platform. I ran Software Update to get Java 6 from Apple, used the Java Prefrences utitlity to set JSE6 as default. In NB I added the JDK6 platform, registered the JDK6 javadocs and noticed that I also have the option of registering the Java source code.
I have three questions:
1) How do I make JDK6 the default in NetBeans. The JDK5 keeps being default after I did the steps above and I don't see anywhere to change that.
2) How do I read the Java 6 source code? I can see sun provides [source code| http://download.java.net/jdk6/] for their supported platforms. I dont see Apple doing the same for its JDK port. What would I need to do to get to read the java SE6 sources? or is it actually hiding somewhere in the /System/Library/Frameworks/JavaVM.framework/Versions/1.6.0/Home hierarchy?
3) Where does the JVM look for the binary code to run when I make a call to, say java.util.ArrayList or any other library. In my naivety I would have assumed it would be a .class file somewhere in the java Home folder, but I don't see anything like it.
thanks in advance,
chrisThis is taken from the help included with netbeans. In response to question 1.
By default, the IDE uses the version of the Java SE platform (JDK) with which the IDE runs as the default Java platform
for compilation, execution, and debugging. You can view your IDE's JDK version by choosing Help > About and clicking the
Detail tab. The JDK version is listed in the Java field.
You can run the IDE with a different JDK version by starting the IDE with the --jdkhome jdk-home-dir switch on the command line
or in your IDE-HOME/etc/netbeans.conf file. For more information, see IDE Startup Parameters.
In the IDE, you can register multiple Java platforms and attach Javadoc and source code to each platform. For example, if you
want to work with the new features introduced in JDK 5.0, you would either run the IDE on JDK 5.0 or register JDK 5.0 as a
platform and attach the source code and Javadoc to the platform.
In , you can switch the target JDK in the Project Properties dialog box. In , you have to set the target JDK in the Ant script itself,
then specify the source/binary format in the Project Properties dialog box.
To register a new Java platform:
Choose Tools > Java Platforms from the main window.
Click New Platform and select the directory that contains the Java platform. Java platform directories are marked with a
in the file chooser.
Use the Sources and Javadoc tabs to attach Javadoc documentation and source code for debugging to the platform.
Click Close.
To set the default Java platform for a standard project:
Right-click the project's root node in the Projects window and choose Properties.
In the Project Properties dialog box, select the Libraries node in the left pane.
Choose the desired Java platform in the Java Platform combo box.
Switching the target JDK for a standard project does the following:
Offers the new target JDK's classes for code completion.
If available, displays the target JDK's source code and Javadoc documentation.
Uses the target JDK's executables (javac and java) to compile and execute your application.
Compiles your source code against the target JDK's libraries.
If you want to register additional Java platforms with the IDE, you can do so by clicking the Manage Platforms button.
Then click the Add Platform button and navigate to the desired platform.
To set the target Java platform for a free-form project:
In your Ant script, set the target JDK as desired in the javac, java, and javadoc tasks.
Right-click the project's root node in the Projects window and choose Properties.
In the Sources panel, set the level of JDK you want your application to be run on in the Source/Binary Format combo box.
When you access Javadoc or source code for JDK classes, the IDE searches the Java platforms registered in the
Java Platform Manager for a platform with a matching version number. If no matching platform is found, the IDE's default platform is used instead.

1.1 vs 1.4 : SDK API's and how they relate to JVM versions
Hey all,
I'm hoping some Java expert/guru/enthusiast can help me understand a little (OK, a lot) more about designing applets for backward compatibility .
My situation is that I need to design applets which are compatibile with the built-in Java features of Internet Explorer and Netscape 6.x - which appears to be JVM versions 1.1.4. I know going with Java2, JDK 1.4, web start whatever would be MUCH better, and will do whatever I can to push clients to plug-in & non-MS browsers, etc. etc., but believe me, supporting MS JVM 1.1.4 is a requirement...
...So my question is, are there any things added to the JDK since 1.1.4 that can be used in a 1.1 JVM? If so, how would I be able to determine what those things are without testing them all?
Like could i take java source for some 1.4 SDK code and add them to a 1.1 project? how do I know if the api requires a new intrinsic or not? (native keyword?)
Also, I'm using the 1.4 SDK compiling for 1.1 targets, aside from the 1.4 SDK api's & packages, will there be any code I can write that will happily compile for a 1.1 target but then mysteriously fail when testing? What I mean is, if I use a new language feature or compiler feature since 1.1, will the 1.4 compiler's byte-code still be 1.1 compatible, or will there be some potential run-time problems?
thanksAs a rule of thumb, avoid all swing components (just use awt) because they are only available in 1.2. You can use all enhancements and bug fixes to awt components that are available in 1.4 (even 1.5).

Our Java application is built with java 1.4 version and oracle 10g
Our Java application is built with java 1.4 version and oracle 10g version database, is it possible to upgrade oracle database to 11g?
is it possible to upgrade
Yes. SE and the other editions have a migration/upgrade utility, not seeing any mention of that program in the XE license docs. To upgrade to 11gR2 from 10g, the 10g instance must be at patch 10.2.0.2 or higher.
So if you're a GUI dba, might be out of luck. But the the XE install has the catalog upgrade scripts that need to be run, there is a MOS note explaining the manual upgrade steps.
Or set up a brand new 11g database instance and datapump your user schema(s) from the 10g instance to the new 11g instance. The database doesn't care what java version you're using, it just does what its told with the data. DDL, DCL, DML ... its not much different. Quite a few new features in 11g.
But if you're after JVMs that piece is not supported with XE. -
BUG: Import Java Sources, can delete file contents.
When I was recreating my project files because I had a problem with migrating from Preview 2. I went to import all my source into the new project... via File > Import > Java Sources... This is when I realized I setup the path wrong for the project I had c:\projects\application\projectname\projectname\src for the source where it was suppose to be c:\projects\application\projectname\src.
Anyway instead of recreating again I just changed the Copy to 'c:\projects\application\projectname\src' and I set the copy from to the same exact directory 'c:\projects\application\projectname\projectname\src', then clicked ok to import.
Well 10minutes later after adding the rest of the stuff I need and fixing the directory paths I realized all the source files were there but the contents were deleted!
Wasn't a big deal for me because I backup my files and I just right clicked on the source folder in vista and restored the previous versions (what a handy feature)... But I don't remember getting a warning and why would it delete the contents anyways? Shouldn't it do a check to see if its copying the file onto it self before copying and just skip the copy part and import.
Stupid me for messing up the path but for someone who doesn't backup their files this would really suck bad.
Thanks,
ArtWhen I was recreating my project files because I had a problem with migrating from Preview 2. I went to import all my source into the new project... via File > Import > Java Sources... This is when I realized I setup the path wrong for the project I had c:\projects\application\projectname\projectname\src for the source where it was suppose to be c:\projects\application\projectname\src.
Anyway instead of recreating again I just changed the Copy to 'c:\projects\application\projectname\src' and I set the copy from to the same exact directory 'c:\projects\application\projectname\projectname\src', then clicked ok to import.
Well 10minutes later after adding the rest of the stuff I need and fixing the directory paths I realized all the source files were there but the contents were deleted!
Wasn't a big deal for me because I backup my files and I just right clicked on the source folder in vista and restored the previous versions (what a handy feature)... But I don't remember getting a warning and why would it delete the contents anyways? Shouldn't it do a check to see if its copying the file onto it self before copying and just skip the copy part and import.
Stupid me for messing up the path but for someone who doesn't backup their files this would really suck bad.

Is there any standard pl-sql procedure or java procedure , that gives the version of JVM , within oracle 8i.From the readme.txt I am sure that the version of JVM is 1.2.1 , but I would like to have a function callable from within sqlplus which gives the same result.
Hi Chandrashekaran,
Please note that I can't verify this for you at the time of writing,
but I think that one of the "System" properties gives you the version
of the JVM. So you could write a java stored procedure that retrieves
the JVM version from the appropriate System property. Check the javadoc
for the java.lang.System class. From memory, there is also a method
that lists all the property names -- so you can locate the relevant
one and then use that to get the required information regarding the
JVM version.
Hope this helps,
Avi. -
How to detect JVM version in Internet Explorer
Hello, I have a site I need to do a check to determine if the user has the Sun JVM or Microsoft JVM and the version of each. This needs to be fully client side and preferably in JavaScript.
The problem is I can't seem to grab the JVM versions. Do I use a version number or objectID? If I have to use an object number like this 08B0E5C0-4FCB-11CF-AAA5-00401C608500, where do I find those numbers?
I did a pretty extensive web search and can't find a lot of options. Thanks.Hi
I am also looking for solution for same problem..
While Searching in this forum I came across this thread..
Re: wf installation/monitor configuration
Please install the plugin on the following url http://www.java.com/en/download/manual.jsp. This will view all the images and the applet.

I am now going to try this... Also I have a doubt whether it is because of IE version less than 6 ... As somewhere in requirements I have read IE 6 is required. Cant remember where

Can't find java source to web services tutorial
When I down load the Java Web Services Tutorial zip file, all that is in there are html files. I've read all sorts of references to the source, even a directory structure, but I cannot find the files.
I have gone to:
http://java.sun.com/webservices/downloads/webservicespack.html
And clicked on the Java WebServices Tutorial, v1.5_01 Download.
The java source files to the tutorial are NOT in that zip file.Hmm, the URL for the tutorial you gave isn't working for me.
I've checked a bit more through the tutorial and JWSDP examples, and they all match for me. I'm looking at JWSDP version 1.5, and the tutorial here:
http://java.sun.com/webservices/docs/1.5/tutorial/doc/index.html
I can't find a 'HelloService' in this tutorial (I also have the tutorial downloaded, grep gave no results). The tutorial refers to, for example, to an example in <JWSDP_HOME>/xmldsig/samples/validate, which I have in my JWSDP. (The page that refers to this example is http://java.sun.com/webservices/docs/1.5/tutorial/doc/XMLDigitalSignatureAPI8.html#wp511406)
If you're really looking at the tutorial version 1.3 (as the URL looks) that could explain it. So, my hunch is a version mismatch, but I could be way off the mark.

Recommended JVM Version for ZfS 6.5 SP1 on NetWare 6 SP5 w/NCS
Quick question - what is the recommended version of the NetWare JVM to use
with ZfS 6.5 SP1? I'm running NW6SP5, ZfS65 with SP1 applied, and Tomcat
3.3. Right now I'm using JVM 1.4.2_6 and just wanted to verify there are no
known issues with JVM 1.4.2_6 playing well with ZfS 6.5 SP1. Running on on
a 2 node cluster.I plan to add ZfD 6.5 SP1 to the cluster soon - primarily
for HA inventory services. Thanks in advance for any input.Ron,
Thanks for the general advice. That's what I thought, but sometimes we
all need a sanity check. Especially when you see java thread death
messages when the distributor starts up :-) Not due to the JVM.
