Java SE Embedded for ARM9 (ARMv5 Linux - Headful) gets rmiregistry failure

Hi, all,
I am using a embedded platform with TI Davinci ARM9 processor. I meet a technical problem when using Java SE Embedded 6 for ARM9 (ARMv5 Linux - Headful). I have a Java program working well in the PC with Java virtual machine.
However, when this Java program can not run in the embedded platform. There is an error reported: "failed to start rmiregistry". The detailed error message is below:
rmi:
[java] rmiregistry not running
[java] The RMI registry is not running, it will be started now.
[java] If running under Windows you may have to hit ctrl-C after
[java] it has been started and re-run the ant command.
[java] Trying to start rmi registry: rmiregistry
[java] Trying to start rmi registry: nullrmiregistry
[java] Trying to start rmi registry: /bin/rmiregistry
[java] Trying to start rmi registry: null/bin/rmiregistry

[java] rmiregistry not running
[java] rmiregistry not running
[java] java.rmi.ConnectException: Connection refused to host: ; nested exception is:
[java] java.net.ConnectException: Connection refused
I searched in the Java SE Embedded, there is no the file named rmiregistry. However, there is a file named rmiregistry in the PC's Java. Is it the reason caused the failure? Is the package of Java SE Embedded not complete? Anyone get idea how to solve this problem?
Thanks.
Best Rgds,

JAVA Browser Plugin for Mozilla on Linux Debian

Hi!
I run a Mozilla Firefox (iceWeasel) on a DEBIAN.
It does NOT display german or french special characters like "Umlaute öäüÄÖÜß" and alike properly.
The text is displayed within an Applet from a 3rd Party, so i can only change the text which is displayed but no java sourcecode.
The stuff is displayed properly on Windows with IE and Firefox.
Any idea is appreciated!

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.

Hello,
Just a quick question: can we have an official position from Sun regarding support of earlier releases of Solaris with Java RTS 2.1? Our customer is currently running Solaris 10 Update 3 with current Recommended patches, and the 2.1 beta cyclic driver supported this version of Solaris. However with the official release version of 2.1, support for U3 disappeared (only U4 and U5 are now supported). Aside from "rubber stamping" the Solaris build via /etc/release, is there a technical reason why U3 is no longer supported? As long as our kernel is up to date, can we safely use 2.1? Or is it just a case of being unable to officially support and test so many releases of Solaris?
Is this a general rule-of-thumb we can expect in future: only supporting the last 2 updates of Solaris 10?
Your advice is appreciated.
Thanks,
Dave.

I would only mention that your definition is incomplete for this -

and that it's most often referred to now as a Descendent selector, not a contextual selector. It's basically the same as the Compound selector that you have already defined....

Sun java web server for Zlinux (Linux for System Z)?

Hi

Fonts in java apps for win and linux

Hi everyone.
i need to build an application mult-plataform, to run in windows and linux...
but i don�t know waht font i must use...the default font that java takes doesn�t exist in linux (dialog)...
waht font should i use in my app??
thanx

For going multi-platform it is easiest to stick to the logical fonts: Fonts named "Serif", "SansSerif", "Monospaced", "Dialog", and "DialogInput".
These fonts are guaranteed to exist on any platform, although their implementations may be different. If you use others then you'll have to figure out how to deal with cross platform issues.

thanks....
Actually I already view the site many times before but after you told me then I get the idea,that's y working together is better, because i sometimes won't realize my mistake even it was the easiest one...
So i just change my code in NationalityDA.java as
while(rsReturn.next()){
NationalityDO n=new NationalityDO();
n.setId(rsReturn.getString(1));
System.out.println("rsReturn.getString(1)"+ rsReturn.getString(1));
n.setDescr(rsReturn.getString(2));
System.out.println("rsReturn.getString(2)"+ rsReturn.getString(2));
n.setSetupDate(rsReturn.getDate(3));
System.out.println("rsReturn.getString(3)"+ rsReturn.getString(3));
n.setChangeDate(rsReturn.getDate(4));
System.out.println("rsReturn.getString(4)"+ rsReturn.getString(4));
ls.add(n);
Once again, thanks..and my 3 dukes are yours..

Using Oracle driver in JDBC for Unix and Linux based servers

Please, let me know how to mention the Oracle driver within the forName.class(" "); statement in the Jdbc-Servlet for Unix and Linux based servers.
I'm using Windows-OS for Java programming. Should I have to use the same environment(Unix/Linux with Oracle) for compiling or just compiling, mentioning the driver in the java program would suffice?
Please, Help me.
Thank You.
from,
Silas eschole.

[email protected]

I've used Oracle's thin driver like this:
Class.forName ( "oracle.jdbc.driver.OracleDriver" );
Connection DBConnection = DriverManager.getConnection("jdbc:oracle:thin:USER/PASSWD@database" );
You need Oracles client classes ( e.g. classes111.zip ) at run time, not during compilation.
Thin client connects directly to the Oracle DB, so the database description is like PORT:MACHINE:SID
Connection is made through Oracle's listener even when your DB is in the same machine that your program is running. Port number is propably 1521 or 1526, depending on your listener.ora definitions and used Oracle SQL*Net version.
