I believe you can detect the type of OS and VM by looking at the system variables.

Look at System.getenv() or System.getProperties(). Just enumerate through either list to see what is in there.

Following on from jschell's answer the values that will be most useful are

os.arch
os.name
os.version

which are returned by the System.getProperties() method.

how to make screen sharing in java

jschell13-Jul-12 11:57

13-Jul-12 11:57

The simple answer is that you can't.

Java runs an an application so it doesn't have access to the 'screen'. It is possible to share the application with another application though.

One could do something with Java but it would require writing something in another language besides Java (like C++) and then have the java app interact with the C++ code. Although I suspect in such a case the java code itself might be only a small part of the overall solution.

I've never done this before but maybe I might be of help if I just gave you the layout.

For the simplest, you could capture the screen into a PNG and stream it to the other party. Bitmaps are "heavy" when it comes to this. If you want to try it with me we can do it.

I don't suspect that this would work for 'sharing'. Viewing perhaps. The problem is that the target computer would then need to analyze each picture to identify components, such as icons, windows, etc, before the target user could interact with it.

Interaction is not done on the visual level. The visual level is just feedback or presentation of what is happening underneath. You'd want to stream mouse state packets containing the mouse data(i.e, location, keys pressed etc).

Java SE or EE

Hello,

I am in doubt whether to install Java SE or EE. SE is newer in version than EE, but I need EE because I plan to work with web services. In other words EE edition I found comes with Java 6, while SE with Java 7 (I found EE with 7 but named Web Profile). Here are the links I plan to use, for SE http://java.com/en/download/index.jsp[^] and EE http://www.oracle.com/technetwork/java/javaee/downloads/index.html[^].

What do you suggest (which one to install or how to combine if possible)?

EclipseLink + Foxpro(Using eclipselink and JPA 2.0 with foxpro database.)

13-Jul-12 11:54

You might want to start first by investigating which container (what EE runs in) you want to use.

The container should dictate which VM version you should target.

I am having some issues using eclipselink 2.3.2 with a foxpro database. Connecting and using the database isn't the problem. The problem is that we use another foxpro application on the same database and there are times when the other app can't update a record. The java app that uses eclipselink doesn't have a problem updating. But the only way to fix the problem in the foxpro app is to actually close the java app. So the question is, is there something that might not be obvious that I am missing that either eclipselink or jdbc:odbc does that would cause a lock on a table?

Here is the persistance.xml setup
<property name="eclipselink.target-database" value="org.eclipse.persistence.platform.database.DatabasePlatform"/>
<property name="javax.persistence.jdbc.url" value="jdbc:odbc:MyODBC"/>
<property name="javax.persistence.jdbc.password" value=""/>
<property name="javax.persistence.jdbc.driver" value="sun.jdbc.odbc.JdbcOdbcDriver"/>
<property name="javax.persistence.jdbc.user" value=""/>

The frustrating part is that we are not able to reproduce any of the errors our client is getting in-house.
Our clients are running on Java 1.7, Windows Server 2008R2 running on a Virtual Server.
Any help would be appreciated. Thanks.

Presumably you are aware that that product is no longer supported and has been discontinued. The last support release was in 2007. So creating a migration strategy is probably going to be a good idea.

And I wouldn't be surprised if at some time in the future you will no longer be able to get a ODBC driver for it for newer windows versions (although maybe a commercial third party will supply it.)

It would help to know exactly what that means.

Yes, i would love nothing more to move away from foxpro. But unfortunately we won't be able to migrate for a while. One of our main products is stuck in VFP for the foreseeable future.

Java is an island in the Indonesian archipelago. It is part of an island arc behind the subduction trench of the Indian Ocean underneath the Pacific plate, resulting in hydrothermal activity, vulcanism and large earthquakes. More about Java.[^]

I like to mention that "JAVA" is also a slang word for coffee - I don't know if that is the cause of the extensive use, but to my point of view coffee really helps.

No one is going to provide a full solution in this way, you need to start by doing your own research into the classes and Java frameworks that will help you. Start here[^] and see which of these can be of use to you.
