Jave ME Embedded support KEIL MCBSTM32F200 and Raspberry Pi Model B ONLY???

I am a JEE developer and quite new to Java ME Embedded ( just started 12 hours ago), I am confused in following questions, please help, thanks!
1. Java ME Embedded 3.3 is support KEIL MCBSTM32F200 and Raspberry Pi Model B ONLY? Or any ARM Cortex M3/RTX and ARM 11/Linux architecture? Does if have supported embedded board/architecture list?
2. If the answer to #1 is no, does that mean that I the reference implementation KEIL MCBSTM32F200 can be used on any ARM Cortex M3/RTX architecture and Raspberry Pi Model B can be used on any ARM 11 architecture?
3. if the answer to #1 is no, how should i choose the embedded board for Jave ME Embedded for general purpose (give some recommendation is ok)?
4. If the answer to #1 is YES, that should be limit usage of Jave ME Embedded on KEIL MCBSTM32F200 and Raspberry Pi Model B; and it can't be used on other embedded device. Or I have to choose Java ME Embedded Client or Java SE Embedded ( this will take more resource, but I only have limitted resource)? Is my understand correct? Does Java ME Embedded has roadmap to support wide embedded device?
Thanks for your time!
Best regards
Michael

Hi Michael,
Sorry for the slow reply. Some answers:
Our officially supported Cortex-M platform for Java ME Embedded 3.3 is the KEIL MCBSTM32F200, which is based on the STM32F207 chip. There is a very similar STMF32407 chip, which is used on KEIL MCBSTM32F400 and we've verified Java ME Embedded 3.3 works there as well. It is likely that Java ME Embedded runs on other platforms using the STM32F207 or 407 chips, but it is impossible for us to verify all these platforms. If you get a chance to try one of those we would love to hear about your experiences.
For Java ME Embedded on ARM11/Linux: RasPi Mod B is our officially supported platform. Unfortunately, the Linux support for some of the peripherals needed by Java ME Embedded (such as GPIO and I2C) is inconsistent - this is a function of the state of the Linux device drivers, not of Java ME Embedded. We are looking into providing wider support for ARM/Linux platforms in the future, which isn't difficult, but we just haven't gotten around to it.
Generally, when deciding on specific hardware for a particular use case it very much depends on the details. If it is a customized system based on the STM32F207 or 407 chips then the need for porting/customization of Java ME Embedded should be minimal. If it is a customized system based on ARM/Linux, please contact us as we are already looking into widening support for ARM/Linux. Finally, if you are targeting a system that is very different from the above, then you can work with Oracle or Oracle partners for an optimized port of Java ME Embedded to your platform.
Finally, we are planning to provide support for additional platforms in the near future - stay tuned for announcements.
Hope this helps. Let me know if you have more questions.
Best,

Help with Transferring the Java ME Embedded 8 Binary to the Raspberry Pi by Using PSFTP

Hi I have saved the file to C:\Temp just as instructed in the Configuration tutorial but when I go to transfer the file to the Pi using PSFTP it fails and says "error while writing : failure" has anyone else run into this problem?

Is it possible you unplugged the Pi while it was running the AMS? We have found that this seems to corrupt the jwc_properties.ini file.
A good practice is to always shut down your Pi with sudo halt, before unplugging the power.

Java SE Embedded hardware interface support

What are the available options for integrating with hardware interfaces with Java SE Embedded?
- I've noticed that the Java Comms API doesn't seem to have any recent activity, and is only provided for a small number of os+hw combinations.
- A number of community posts elsewhere recommend RXTX (http://rxtx.qbang.org/wiki/index.php/Main_Page) - it looks like this is limited to just serial or parallel ports though - is this correct? Is this widely used?
- I've noticed libraries like Pi4J (http://pi4j.com/) provide a great Java API to interact with the GPIO pins on the Raspberry Pi. This is a great approach if there is a library like this for the hardware platform you are running on, but if there isn't what are the alternatives? Do you have to write your own C shared libraries to integrate with the hardware, and then use this via JNI?
Thanks, Kevin

See Java for Mac OS X 10.5 Update 1 adds support for Java SE 6. Note the system requirements exclude PPC machines.
Apple does not drop software support, however, they stop updating older versions because the requirements of new software exceed what older hardware can provide. This is simply the result of obsolescence. Your version of OS X is capable of supporting Java SE 6, but your hardware is not able to run that software.
If it's essential that you be able to run new versions of software that have requirements that exceed what you hardware or OS can support, then you have to upgrade accordingly. Sell your PPC machine or donate it to a reputable charity or local school/church. Then buy a new machine that can run the software you wish to use.

IAS is Oracle's next evolution of the web server and application server
product technology superceeding the Web Application Server (WAS) and Oracle
Application Server (OAS) product lines.
IAS SERVLET API JSP API EJB API EJE VERSION
VERSION VERSION VERSION VERSION SUPPORTED
9I(1.0.2) 2.2 1.1 1.1 817
8i(1.0.1-NT) 2.0 1.0 1.0 816
8i(1.0.0-UNIX) 2.0 1.0 1.0 816
The IAS product contains two Java Virtual Machines (JVM) within it's
architecture.
They are called :
1) APACHE JSERV servlet engine
2) ORACLE ENTERPRISE JAVA ENGINE (EJE)
APACHE JSERV servlet engine
The APACHE JSERV servlet engine is an EXISTING product licensed from the
apache group which supports the servlet api 2.0.ONLY.
The APACHE JSERV product does not support ANY JSP's unless the customer
installs a third party jsp engine.
The IAS 8i/9i which has the APACHE JSERV product embedded in it, comes with
Oracle's JSP engine (OJSP) already integrated into it. OJSP supports JSP's up
to the specific JSP engine version documented in the Oracle Universal
Installer (OUI) for the 8.1.7 RDBMS or the IAS products. It is also documented
in the product's release notes.
Oracle ENTERPRISE JAVA ENGINE (EJE)
The EJE formerly known as :
1) Oracle 8i Java Virtual Machine (JVM)
2) JSERVER component,
3) Aurora JVM
was originally releas ed in the RDBMS 8.1.5 database with jdk 1.1.6 based java
support.
The currently supported versions of the Oracle 8i RDBMS, versions 2 and 3,
also known as Version 8.1.6 and 8.1.7, respectively, provides a jdk 1.2.1
based java virtual machine support.
"EJE" Version 816
This EJE, found in rdbms 8.1.6 and IAS 8i, contains support for the ejb
api 1.0, corba, and java stored procedures.
"EJE" Version 817
This EJE, found in rdbms 8.1.7 and IAS 9i, contains support for the ejb,
corba, and java stored procedures as well as the Oracle Servlet Engine (OSE)
which provides support for the servlets 2.2 api and JSP 1.1 api.
Note :
EJB support in the "EJE" Version 817 has been upgraded to comply with the EJB
1.1 api specification which includes "entity beans" support.
What is the bottom line ??
1) Servlets deployed to the APACHE JSERV must comply with servlet api 2.0.
2) Servlets 2.1 or higher are only supported in EJE's OSE component found in
the rdbms 817 or ias 9i products. Servlets api 2.0 can also run in the OSE.

which jvm is used by jserv ?? EJE or a separate jdk ?
The Jserv servlet engine is running in a separate jdk JVM external to the EJE jvm which is embedded within the "database" component of ias and the RDBMS.
See the reference below for more details ...
if jserv only support old apis, why it is in oracle's products ?
i would assume that the oracle servlet engine was under development when ias 8i was released and became available in time for the ias 9i and rdbms 817 products.
looking back in history leads me to believe ias 8i was a migration path to get to ias 9i or rdbms 817.
Based upon the long history of new releases of every oracle product being upgraded with new features, it's reasonable to assume that these products will continue to evolve.
when I deploy a jsp how to deploy in the right servlet container ("EJE") ?
as documented in the reference below, you can deploy JSP's to either the apache jserv jvm or the EJE since the ORACLE JSP engine functionality is in both jvm's.
there are many posts where you can see that people have deploy in jserv and they have problems because they don't use the right container (servlet 2.0 instead of
servlet 2.2) http://technet.oracle.com:89/ubb/Forum2/HTML/006349.html
when ias 8i came out this was clearly an issue since servlet support was at api 2.0, and the current servlet api was probably at 2.1.
oracle clearly made every effort to get ias 9i released quickly to supply a servlet 2.1 and 2.2 capable engine to resolve this issue.
since ias 9i and rdbms 8.1.7 are available this is no longer an issue.
The reference below explains the architecture and understanding it would eliminate a lot of "deploy to the wrong ias 9i component" issues.
so why jserv is bundled with oracle 8i/9ias since EJE support the right api version ?
if in ias 9i release , oracle had removed the jserv component without any advance warning, many customers would have been very upset since oracle makes every attempt to give advance notice before removal of functionality.

Real-time support in Java SE Embedded

From what I understand, Java SE Embedded is a slimmed down SE JDK/JRE compiled to support different typical embedded processors, ARM etc.
Does Java SE Embedded provide any additional support for handling realtime situations? For example, are there any JVM modifications to guarantee response times and execution times for time critical scenarios?
The reason for asking is that I know a while back there was a specific Real Time Java release - did any of this technology get rolled into the new SE Embedded?
Thanks.

Yes, Java3D or an openGL toolkit such as JOGL or LWJGL is probably the best choice. Bearing in mind that Java3D is on the way out you may want to look at using OpenGL although there is much talk over at javagaming.org of putting together an open-source Java3D-like scenegraph renderer for the openGL toolkits and the guy working on it is very good indeed so it will probably happen. Assuming that it does, time spent learning Java3D is not wasted time.
If you are interested in Java3D download the API and tutorials and see how you get on with it. I put together a fairly gaming oriented tutorial here http://www.newview.co.uk/e/tutorials/java3d/index.jsp which may help you get started.
If you are serious about writing games in Java you will want to get over to the javagaming forums http://www.javagaming.org/cgi-bin/JGNetForums/YaBB.cgi because that is where you can generally find the best advice. There are a number of old threads on this question there and you will probably find it well worth your while to look through the older posts on it.

Java Plug-in / JSObject support with IE and Firefox

Hi there,
Basicaly, the idea behind is to write objects in Java to replace or extend functionnalities of a web page (like XMLHttpRequest object). Those objects should support event handler writen in Javascript.
My first idea was to create JavaBeans and instantiate them through OBJECT tags in HTML (not as ActiveX objects). I don't find a way to instatiate a Javabean which was not also an applet.
Does someone knows how to ?
Anyway, the OBJECT tag may not work with Netscape. So, I went to use the APPLET tag with the Sun Java Plug-in.
I've made some tests with IE and Firefox and there is at least two differences between them (both use the Sun Java Plug-in) :
1/ Firefox / JSObject
When you pass a Javascript object to a Java method, it seems that you
cannot use methods like 'getMember', 'call', etc on this object.
(invocation of the method works but returns null)
But, if you access the same object form inside Java starting by
JSObject.getWindows(...) and so on, it works fine.
IE works in all cases.
Example, with the Java applet and HTML below :
. Java applet :
| package JavaJS;
|
| import netscape.javascript.*;
|
| public class FirefoxApplet
|        extends java.applet.Applet {
|   netscape.javascript.JSObject win = null;
|
|   public void init() {
|     win = netscape.javascript.JSObject.getWindow(this);
|   }
|
|   public Object getJSObjectMember( netscape.javascript.JSObject jso, String member ) {
|     return jso.getMember(member);
|   }
|
|   public netscape.javascript.JSObject getJSObjectFromPath( String jsoPath ) {
|     String [] jsoNames = jsoPath.split("\\.");
|     netscape.javascript.JSObject jso = win;
|
|     for( int i = 0; ( i < jsoNames.length ); i++ )
|       jso = (netscape.javascript.JSObject)jso.getMember(jsoNames);
|
| return jso;
| }
|
| public Object getJSObjectPathMember( String jsoPath, String member ) {
| return getJSObjectMember(getJSObjectFromPath(jsoPath),member);
| }
| }

. Firefox output :

| object o, member s
| object o.o, member s
| null
| null
. IE output :
| object o, member s
| object o.o, member s
| object o, member s
| object o.o, member s
| object o, member s
| object o.o, member s
2/ Internet Explorer / JSObject
As we have seen in the previous example, passing Javascript object to
an applet method works. Here, the problem comes when a Javascript object
is pass to a method that's not an applet's method.
If within the applet, you instantiate a new Java object and then
call from Javascript a method on this object with a Javascript object as
parameter then an Exception is raised when invoking that method.
Firefox works fine here.
Example, with the Java applet and HTML page below :
. Java applet :
| package JavaJS;
|
| public class IEApplet extends java.applet.Applet {
|
|   public void init() {
|   }
|
|   public Object echo( Object object ) {
|     return object;
|   }
|
|   public Object newEcho() {
|     return new Echo();
|   }
| }
. Java Echo class
| package JavaJS;
|
| public class Echo {
|
|   public Echo() {
|   }
|
|   public Object echo(Object object) {
|     return object;
|   }
| }
. HTML page :
| <HTML>
|   <HEAD>
|     <TITLE>IEApplet</TITLE>
|     <META http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

|         o : {
|           s : "object o.o, member s"
|         }
|       }
|
|       function go() {
|         print(iea.echo(o));
|         print(iea.newEcho().echo(o));
|       }
|
|       function print( text ) {
|         txa.value = txa.value+text+"\n";
|       }

|       function loaded() {

with this Exception on the second method invocation :

in a Java object with an applet method and then use this Java object as
parameter.
Anyway, my questions are : regarding points 1/ and 2/ are these bugs with the Sun Java Plug-in ? or someone could explain these behaviors ?

Which application server supports EJB 3 and Java EE 5?

Hi all,
I want to develop an application using EJB 3.
I was planning on using JBOSS 4.0.4 as application server, but I am not sure whether EJB 3 is fully supported.
Which application server supports EJB 3 and Java EE 5?
Thanks

Just install it using the EJB3 profile in the installer. Don't use the "All" profile
and think EJB3 is included in it :)

I have made some progress.... I can print wirelessly from my printer now, but I can't set the printer itself to be wireless. I had to move my printer downstairs to where my router is...which is not that convient. I printed up the page you asked about....and as expected, it says it is off line and there is no IP address. So now I need to figure out how to make my printer itself wireless. I did download the HP driver I needed...but I can't access it to do anything else. It seems l like I am missing a step... or I need to hook up my computer itself to the printer to help get the printer to be wirelss, but I can't hook it up because there is no port for me to do that (no port that looks like a phone jack). I am guessing I would need a different type of cord, but I am not sure what kind of cord that would be! Ugh!

Tools.jar for Java SE Embedded

Hi all,
I believe Java SE "for Embedded" supports JVMTI,
but tools.jar is not found in any builds such as for ARM and x86.
Without that, the instrument or attach API defined in JVMTI
is not able to work on Java SE for Embedded.
Any suggestion would be appreciated.
Thanks in advance.

Well, I would guess that questions about embedded java would be ok here, questions about J2ME programming would be better suited for the "CLDC and MIDP" forum and Java SE questions would be better someplace here. But don't expect too much, there is not a lot of activity in the forum ...

Problem transferring Java ME Embedded 8 to RPi

Greetings,
I am trying to catch up on the course material and am having trouble getting the Java ME Embedded 8 binary. Specifically I cannot connect to the 192.168.1.105 address. Has anyone else experienced this? Any advice on what I can do to remedy this issue?
Thanks,

Did you set up the Raspberry Pi to have that IP?
Otherwise it might have another IP.

Support B+ pins and possible to setDirection ?

I am doing the simple GPIOLEDtest program from the course but I am trying to do it on GPIO04. It does not allow me to open it since it seems only to allow this pin as input.
When I try to set the direction to 1 which is OUTPUT, I get an error message ""java.lang.UnsupportedOperationException: Incompatible direction"
I did set the API permission to allow me to change direction, but it does not work.
Also, when I try to use B+ GPIO pins like GPIO16 I also get an error message "DeviceException: Device 16 not found"
I am using me version 8.1, which should offer support for the model B+.
Is it something I am doing wrong or are these restrictions in javame8.1 ?

Never mind. I found the answer myself. I was trying to change the direction after opening the device with the device manager. I now found I need to do it as part of the opening of the device by giving it the right config right away.
So I am now using the code:
GPIOPinConfig config1 = new GPIOPinConfig(portID, ledID, GPIOPinConfig.DIR_OUTPUT_ONLY,DeviceConfig.DEFAULT, 0, false);
        LED = DeviceManager.open(config1);
Instead of:
        LED=DeviceManager.open(ledID);
        LED.setDirection(1);
This is the same approach as when configuring switches in the later lessons.
Now I can change the exiting pins to output and I can also use the new pins of the Raspberry B+ model to driuve the LEDs, wuthout error messages.

Java API for Adobe Flex(AIR and Browser)

Hello Community,
Sometime ago i started the project located at: : http://code.google.com/p/gwt4air/ , wich primary goal was to bring another approach on writing AIR application by providing a Java API for the AIR API. On top of that i added support for PDF and Excel generation using Java.
I m glad to announce that the project will now add support for the Flex Framework
I wrote a post about it on the main page.
The Idea behind it is to give Java Developers a more simple way to write Flex Application by leaveraing a swing like API.
I hope this project will be a good alternative to the MXML+ ActionScript approach and looking for people willing to join the project.
Regards,
Alain
