Java on Nokia N900 Maemo 5 for example Opera Mini
 

http://maemos.ru/wp-content/uploads/...220-000744.png

1. Go and this archive java_nokia_n900_maemo5_opera_mini.zip
2. Extract your PC. Inside the folder jre
2. You copy the folder c jre in the folder / home / user /
(I copied to a memory card, and then moved through the MC in / home / user /)
4. Under Root (root) execute the following commands:

cd / home / user / jre / bin /
chmod + x java
chmod + x opera.sh
5. Run a command

. / opera.sh
6. Press ENTER (Start does not work)
7. If the internet (WiFi for example) is not included, turn - the program itself can not yet.

P.S. Opera Mini is not the only application in Java that can run on the Nokia N900 Maemo 5 ;)

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

I think yes, why not?

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

JRE needs to be optified since I don't want to waste my precious rootfs.

Edit:

Wait a sec, it in fact goes to home!

Edit:

I need to verify this.

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

Wow, it's actually working, but something far from usable, more like a proof of concept thing:

Any updates concerning opera mini?

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

How do you get past the first screen with "accept" or "exit"? Neither stylus nor the enter key seem to work.

EDIT I did it - don't know how. Works well

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

This seems to work much better with the beta release of Opera Mini 5, currently available at http://www.opera.com/mini/next/download/.

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

can anybody tell commands to install opera mini in n900 through x-terminal....

edit:(x-terminal)

i couldnt be able to execute chmod +x java , chmod +x opera.sh commands

permission denied ....

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

You need to be root to execute the command..

install rootsh from the repos, then go to the Xterminal and type:

sudo gainroot

Then you should be able to execute your command :)

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

Can someone please tell me how to install this?

I haven't installed anything on my N900 and would like to get Java apps working.

Install embedded java version? (which version exactly?)
Then run this file?

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

hi' thanks first!
I did and root shell enabled but still it says permission denied when trying to execute chmod +x java ,chmod +x opera.sh , ./opera.sh

Do you have a moment again ? please......

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

were you able to install 5 Beta ?

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

do you have those files saved under /home/user/MyDocs? if you just copied them over using Mass Storage mode, that's very likely.

/MyDocs is a VFAT partition and doesn't support the executable flag. you have to copy the files on a linux filesystem first, /home/user for example.
then you should be able to set the executable flag using chmod +x.
(btw, that's step 3 of the howto in the first post of this thread.)

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

when i tried unzip , the xterm returned that "end of central directory signature not found"

whats up ? the filename is correct cuz i used tab..

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

I sooo want this to work, but only if it solves the three issues I have with the default browser:

1. A one click 'back' button/gesture
In Opera Mini on my E61i, I just pressed the left navigation key to go back. With the N900 browser I first have to swipe and then select a page to get to the previous one.

2. Instantaneous display of 'back' page.
On N900 it seems the page has to be re-rendered. On OM it was immediate.

3. Speed!
I liked the speed of OM. especially for 'text heavy' sites, most notably my Bloglines account. Even with faster processor, I feel the N900 is slower.

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

The backspace key takes you back to the previous page, that's one klick, no?

Not really a fair comparison: opera mini doesn't do much on the device, the pages are pre-rendered on Opera company servers and then send to the device. Opera mini is more a client/gui than a browser...

But I like it, too. worked fine on my Motorola Razr... :)

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

I originally posted this reply in another thread, but it seems appropriate to add it again here:

1. Start X-Term as root
2. Install your version(s) of Java and MicroEmulator to /home/opt/. use chmod +x java to grant executable rights.
3. Create a symlink to use Java from the command line:
ln -s /home/opt/java/bin/java /usr/bin/java
4. Navigate to: cd /usr/share/applications/hildon
5. Use the ls command to list the .desktop files in the folder
Copy an existing file with a new name:
cp x-chat.desktop microemu.desktop
6. Using Leafpad edit the file: leadpad microemu.desktop
7. The edited file should look something like this:
[Desktop Entry]
Encoding=UTF-8
Name=MicroEmu OpenJDK
Comment=MicroEmu OpenJDK
Exec=java -jar /home/opt/microemulator-2.0.4/microemulator.jar --resizableDevice 800 375 /home/user/MyDocs/opera-mini-4.2.jar
Icon=xchat
Type=Application
X-Osso-Type=application/x-executable

Change the icon to anything you like

Save the file and look in the applications menu for the new shortcut. It should launch MicroEmulator full screen with Opera Mini ready to start

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

I got it to work, but only after I changed the '--resizableDevice 800 375' part. Maybe that device needs to be added to the version of MicroEmulator I used (the one from the link in the FP)?

This is what I did to get OperaMini 5 running from the menu (based on Darkgunmans instructions, italics are the differences):

---------
1. Start X-Term, type 'sudo gainroot' for root access.
2. Copy the 'jre' folder to /home/opt/ (including the Opera 5 jar & jad files)
cd to /home/opt/jre/bin and use chmod +x java to grant executable rights.
3. Create a symlink to use Java from the command line:
ln -s /home/opt/jre/bin/java /usr/bin/java
4. Navigate to: cd /usr/share/applications/hildon
5. Use the ls command to list the .desktop files in the folder
Copy an existing file with a new name:
cp x-chat.desktop microemu.desktop
6. Using Leafpad edit the fileby typing: leadpad microemu.desktop
7. The edited file should look something like this:
[Desktop Entry]
Encoding=UTF-8
Name=MicroEmu Opera
Exec=java -jar /home/opt/jre/bin/microemulator.jar --device org/microemu/device/resizable/device.xml /home/opt/jre/bin/opera-mini-5.0.17443-advanced-en.jad
Icon=Opera
Type=Application
X-Osso-Type=application/x-executable

Change the icon to anything you like. This post explains how to add your own icon. I made this one:http://www.mmk.dds.nl/Opera.png


Save the file and look in the applications menu for the new shortcut. It should launch MicroEmulator full screen with Opera Mini ready to start (using the enter key, the start button doesn't work)
-------

The display defaults to 800x400, so it would be nice to get the 'resizabledevice' working. Does anyone know what I should do differently?

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

@ maartenmk

Thanks for the detailed & corrected How-to, I've followed it but opera is not loading, I get a window titled "MicroEmu Opra" with the spinning loading thingy, then it exists completely and nothing happens.

i've triple checked everything and it seems ok, so any help would be greatly appreciated

Edit : I will go through the steps again after lunch break, although I don't think I've missed/screwed any of them, but who knows

Edit 2 : Rechecked and everything seems in order, but nothing loads :(

Edit 3 : I'm able to launch Opera using ./opera.sh command, so it works, so I'll check my steps again.

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

:confused:

Can u pls post a video on how to install java aplications on nokia N900. I'm v confused..

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

Forgot to add - if you download the newest version of microemulator http://code.google.com/p/microemu/downloads/list , then the start button works, as well as other text entry dialogs in Opera Mini.

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

Cant anyone get this optified and into devil. There is alot of noobs that would like this on the N900, me inkluded. ;)

BTW. New wersion out yesterday i think..Opera Mini 5 beta 2:
http://www.opera.com/mini/next/

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

No, as the instructions are perfectly fine.
If you don't understand them, a video will not help you either...

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

Does anybody know how to add more items to the microemulator menu? Or, which i'd prefer: is it possible to start an app directly from xterm and skip the microemulator menu?
At the moment i'm using seperate scripts (opera4.sh & opera5.sh) to open j2me apps, but it's obviously possible due to the presence of the menu..

Thanks, Killian

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

I haven't found an answer to that one. The MicroEmu documentation doesnt provide a vommand to execute or run an application straight away. Best I can suggest is contact the author of MicroEmu and ask for it as a feature request. I have a few suggestions of my own I wish to pass along so I will mention this too.

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

To run opera directly from command line type :

./java -cp opera-mini-4.2.14912-advanced-en.jar -jar microemulator.jar --device org/microemu/device/resizable/device.xml Browser

[]'s

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

I use this command from a desktop file: java -jar /home/opt/microemulator-2.0.4/microemulator.jar --resizableDevice 800 378 /home/user/MyDocs/opera-mini-4.2.jar

Only issues i have left to figure out are launching Opera without having to click Start in MicroEmulator, and how to launch Microemulator in full screen without the title bar.

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

yeah I'm trying to figure that out aswell, I'm managed to put an Icon for opera Mini but have to click start each time.

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

Managed to solve one part of the riddle at least. The current snapshot of v3 of Microemulator automatically launches applications if specified in the command line.
Opera launches straight away now!

http://snapshot.microemu.org/microemulator/download/

My suggestions for the next incarnation of this would be the ability to hide the menus and resize button, and allow usage in full screen.

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

it opens ,installing....could not store resource unable to create recodStore directory!
wt could be the reason?

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

I am also very interested in having Opera Mini in full screen in MicroEmulator (no title bar, menu bar & status bar), do you guys have any idea if that could be possible with the MicroEmulator headless mode ? or what is the use of the headless mode ?
(I could just check it at home tonight but was wondering if you guys already had experience with this "headless" mode)

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

headless = no GUI elements, cmdline/daemon only.

opera will fail to start in a headless JVM.

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

I would be ever so grateful if someone could test whether this Oanda java test applet runs on the n900: TIA

https://fx2.oanda.com/test.html

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

Just so you guys know, this is not a legal project. You're not allowed to redistribute the Embedded Java trial software. You have to download it yourself from here. And it does time out after a while.

You should probably also grab the latest MicroEmulator snapshot, as DarkGUNMAN suggests. It solves several bugs with the older versions.

And then, once you've grabbed the latest Opera Mini version yourself, you've done everything that the original blogger did. But you did it legally.

The OP probably got all their information from this thread here at t.m.o.

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

Hi, I've been using maemo.org ever since I got my N900, back at the end of December. It really is a more than useful site - vital in some respects for this phone.

However I have never been so stumped as this - what I'm sure is very simple - Java installation.

I first tried the simple guide on nokian900applications.com but it didn't work. I also found it a little confusing. The same then went when I tried the step by step guide on this thread. It is not just that it isn't working, but I feel more me it is missing out obvious and simple things, probably because I'm not techy enough.

In most ways I am not even at "noob" level, but I have been very used to installing and altering things in x-terminal through guides on this website.

Please could someone maybe do what someone else suggested earlier on this thread and do a video? Or even a s-t-e-p-b-y-s-t-e-p slow and laborious process, even like it's written for a spastic.

I really would so much like to get Java working on this wonderful phone of mine. And no, unlike some people on maemo.org, I do not just use this for a phone and maybe a play on a demo version of Bounce.

Regards, Charles


p.s. This is my first post, not only on this site, but on any forum. Does it possibly show...?


Oh, and please don't just link me to another guide on this site, I have searched and done everything I have seen to try.

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

is it possible to run symbian apps now right? D: ... like if i downdload a JAR file for a symbian game, and install it, it would work?

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

JAR files are Java files :)
Not symbian....

(Symbian files are sis or sisx files ;))
But yeah, the .jar files should work :)

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

If you want to run Java apps (or J2ME apps), you want to check out the package icedtea6 and microemulator. Do a forum search and you'll find a couple useful threads about both of these. Both have versions in extras-testing, and can be easily installed from there.

Icedtea6 is an optimized Java SE setup for arm processors (like our N900 has) and gives you the ability to run most Java based programs. Microemulator (which requires JSE or icedtea) is a class emulator that can run most J2ME packages within the JSE environment.

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

well, yeah, i used icedtea6 and microemulator, and i could run clash of titans the game for symbian, (there's a lot of websites where you can download the games in .jar format, well... it worked!!! :D:D:D omg! ... the only problem is that it runs kinda slow, but i'm 100% sure it's because i have the wrong resolution, i downloaded one for E61i (320x240) and well, when you select resizable device from options, it kinda stretches the image to fit the WVGA n900's resolution, i triend to manually resize it in the emulator option but didn't work, can any one come up with ideas to make it run smoother? :D

Re: Java on Nokia N900 Maemo 5 for example Opera Mini
 

can u make a simple tutorial on how to do it???
