You have to launch one file instead of *.jar

"./java -jar foo.jar" with foo the name of the jar file you want to launch.

yeh I just typed *.jar as an example. I am putting the complete file name there.

Many java applications are not packaged as runnable jar files. You will need to run something like java -cp x.jar:y.jar com.company.program.MainClass

RE Runescape; the java plugin included in the embedded JRE doesn't seem to work with MicroB or Firefox, so there is no way to run applets on a webpage right now and that is how it runs. Possibly it might work out of appletviewer but I doubt it. Also I think Runescape uses OpenGL so there would be code changes required to use OpenGL ES as well as porting work for the JOGL library.

Got Jetty up and running myself yesterday (see below! ) Not tried to do anything with it really though. Absolutely love this phone!




By the way, for the people struggling to get java executing after a sudo gainroot, you need to edit the gainroot script in /usr/sbin and add the appropriate PATH.

Hi guys, I just spotted this thread and thought someone might know something that could help me..


this is a link to a Jar file (J2ME Eagle Eyes) I used when setting up remote viewing of CCTV on the Nokia N95 - I presume these Jar files won't work on the N900 being a different system altogether?

Thanks for any help.

But all I really want to do is get the N900 to play the streaming .mov file at my ip address - instead I just get a "mediaplayer" icon which, if i click it, tries to save the .mov file to the harddrive of the N900 instead of playing the live video...

Hello,

I installed the Sun Java Se for embedded like Dak described. I tried to run the application "Db Railnavigator" (can be downloaded here: http://persoenlicherfahrplan.bahn.de...=railnavigator ) but it did not work. The error-message was:

java -jar /home/user/MyDocs/javaprogramme/dbmidlet.jar
Failed to load Main-Class manifest attribute from
/home/user/MyDocs/javaprogramme/dbmidlet.jar
Nokia-N900-42-11:~#

Please can anybody help?

Greetings Bernd

@floweih

That's a midlet - so you need a J2ME (Java Mobile Edition) environment to run it in.

What is being discussed here is a J2SE (Java Standard Edition) environment.

I'm not sure what the status is on a J2ME environment for the N900.

To run a midlet:
1. Install JRE
2. Go to http://www.microemu.org/ and download the zip file
3. Unzip the file
4. Go to folder in terminal and run java -jar microemulator.jar
5. Get out your stylus and used the menu to open dbmidlet.jar

You can also use the devices menu to select the resizable device which uses the screen a bit better. Unfortunately the "scale" option seems to be very slow.
I have peggle working for me, but with no sound.

Just downloaded JRE from sun licence says 90 day trial, hope there will be a better solution developed by then.

Ulrik | # 120 | 2010-01-26, 13:59 | Report

Is it possible to install Java on the N900 without the 90-day trial period?
