Dear mikeb,
You mean i just get microemu first. Then for the runtime, i need the "standard" java from Sun's website? Can microemu be used with j2me? Confused


You need to install JRE first. There are pets available. Then download microemulator and place its folder somewhere on your HDD. I have it in root. Then right-click on a jar file and chose " set run-action" in the menu. Set the run-action as: java -jar "$@" for jar files. You can then run microemulator by clicking microemulator.jar

Yes and yes.... java -jar /path/to/app.jar or .jad is the basic usage...

Hi, Mike.

Minimal requirement for microemulator to run is JRE1.4.2 Being ultra anti any large programmes, I would love to have that old version working as it's about 13mb compared to the newer versions at over 40MB in installation size. So, it will be great if one can find/make a pet of that old version. I've tried to download that old version from Java Sun website before but without luck. Any way to get/make a JRE1.4.2pet?

Hmm I have 1.6u0_30 which is a 30MB sfs.

In order to get it an any other older versions you have to join the dev site.... just an email and password job and tell them you work for IBM or something Very Happy.... Has to be the horses mouth as by the licensing nature you are unlikely to find an 'official' download elsewhere.

Unless someone here has one tucked away Smile

mikeb: i was thinking of the possibility of running Java ME instead to keep things light. Would that be possible since most java phones run Java ME?

Well since microemulator is emulating javaME that would have been unecessary if javaME was available on Linux. Then again its an area of which I know little which also means I really don't know

regards

Mike

Hi mike,
thanks for the feedback. was just wondering if i can keep it small. for me, it's a waste of space to install 40mb of data to run a mini browser smaller than 5mb.

Well multiple levels of emulation do take their toll on the electricity bill.

Again jme2 running directly on elf would be a better way but I know not if it exists (is it closed source?)... otherwise why use such as microemulator.

It may be related to the commercial aspect of the whole smart phone apps world... easier to prevent users getting files on a phones embedded system than on a pc.

ok old javas for puppy
http://dotpups.de/dotpups/Libraries/
there are 3 in there...rename pup to zip to get at the files if they won't install.

note from oracle the java ME downloads only appear to have SDK for windows and Macs but I get the feeling you would have something similar to microemulator in the end.

Ok straight from my oracle account as an ace pilot Very Happy the last release of 1.4 installer bin....I might have a play myself Smile
removed to to lack of need and I want the space..pm if you still want this..

I did manage to try operamini.pet (v6.5) and google+chrome.jar (a modded opera mini 4.2) last night. I notice that v4.2 was much more speedy in loading pages even with graphic, but v6.5 was unable to load it fast, with 2 tabs open. any reasin for this? the connection speed was a basic 64 kbps one.

My Opera Mini 7 is very fast. It depends on your connection speed. Yours is very low, imagine how long that will take to open a web page in a normal browser. Make sure the picture setting is set to low resolution in Opera Mini.

Mike, have you tried that older JRE with microemulator/opera mini? Don't want to download it and it doesn't work properly. BTW, how about making a .pet or SFS of this available.

Why are we always posting the same time? Make an SFS file or pet file available if you please, thanks
