How OBML works

When a web browser rendering using OBML requests a web page from a server, the following events occurs –

  1. The web page request is sent to a large, power server farm (like

    1. I guess, you’ve not configured properties of MicroEmulator.jar‘s shortcut file.
      To configure that, follow steps below:

      step 1: Open MicroEmulator folder > right click on microemulator.jar > send it to desk top.
      step 2: Open properties of that shortcut file you’ve created on desktop.
      step 3: In Start In Field, paste your MicroEmulator directory path within double quotes.
      step 4: In Target field, paste the line as below.

      C:\WINDOWS\system32\java.exe -cp microemulator.jar;lib/microemu-jsr-75.jar –impl org.microemu.cldc.file.FileSystem org.microemu.examples.fcview.FCViewMIDlet OperaMini7.jad

      Step 5: Replace OperaMini7.jad with your Opera Mini’s jad file name – with jad extension.
      (suppose you have om6.jar & om6.jad, then replace OperaMini7.jad with om6.jad)
      Step 6: Place your Opera Mini jar and jad file in MicroEmulator folder.
      Now, you’ve configured the shortcut file. Open that shortcut file by double clicking it. Those directories (filesystem, c, e) will be created.
      Now place your obml files in c or e within filesystem directory.

      It’ll be like below




        1. Sorry, my mistake – I’ve not noticed that the dashes “-” was converted to a unicode character looking similar to a dash. I fixed the post, now it will be like this –

          C:\WINDOWS\system32\java.exe -cp microemulator.jar;lib/microemu-jsr-75.jar --impl org.microemu.cldc.file.FileSystem org.microemu.examples.fcview.FCViewMIDlet OperaMini7.jad

  1. Hi, I was finally able to install OM, and was successful in saving and downloading the file, so I think you can disregard the query I’ve posted on your other post. But the problem is, OM8 apparently can open only obml16 files? Is that right? It can’t seem to read all the obml files I’ve saved using OM4. Is there anything else I can do to open them? Thanks in advance.

  2. hi.thanks for the post.i am running win 8.1 and it says shortcut path not valid.and in system32 there is not java.exe in my pc.i have jre 8.0.250 installed.what should i do.

  6. Hi Arpan, I have followed your procedure to the letter but fail to go past step 4. When I paste your line in the target field, the response I get is “The name ‘C\WINDOWS\System32\java.exe in the Target box is not valid. Make sure the path and file name are correct. I running Windows 10 with Java 8u91 installed and trying to run opera mini 8.0.35626. Any suggestion would be most helpful. Thank you

  7. Hi, Just discovered that java is installed in Program Files (x86) and not Windows/system32. Problem is I have no clue on how to change the path to this location. I’m not that computer literate by any stretch of the imagination so I would be eternally grateful if you could provide an idiot-proof guide to change the path for the target box. Once again thank you.

  8. Hi Arpan, opera mini-8 can not read obml files pasted from my phone. I have changed a few at random to obml16 but without any success. Any ideas on what I could have mistakenly done to prevent them from being read. Much respect for the post.
