Hi, I am unable to install Google maps or any application, post download it gives error "invalid JAR file". I want to install games and google maps on my cell.


Here's a quote of someone who had a solution to your problem:

"The Samsung star GT S5233A does not support apps that are directly put into its memory... Find the suitable applications on the internet.. your .jar files.. Upload these to any free wap uploader such as davidpye.com/wap and download them files from that site through GPRS.. there is no other way you can put softwares in it... I've tried the wap uploader method and it works...!!"

You need to download and install JAVA to open these files.

1. Follow this link: http://www.java.com/en/download/index.jsp

2. Click on "Free Java Download"

3. Click on "Agree and Start Free Download"

4. Click Save File

5. Open file once it is downloaded.

6. Click "Install" when the JAVA installer opens.

7. Uncheck "Include FREE McAfee Security Scan Plus" unless you want this program

8. Click "Next" and close all browsers.

9. Restart computer if asked to from the installer.

10. Open up the jar files you were unable to open prior to installing JAVA.

That should do it; good luck and thanks for using FixYa.

I am unable to install ani MIDlets on a Sagem Cosy phone. I've tried - simple copying to the phone and clicking on the file (both jad and jar), nothing happens - trying every option in the Entertainment...


1. Create simple html-file (put correct jar and jad names in href links): <html> <body>
<h1>Install Java Application</h1> <p>Select midlet to install</p>
<a href="./USBTest.jar"> USBTest.jar</a> <br> <a href="./USBTest.jad"> USBTest.jad</a>
</body> </html>
2. Copy created html-file and jars/jads to the same folder on the phone, e.g. Others folder.
3. On the phone, go to Multimedia and select your html-file - it will be opened in HTML browser.
4. In HTML browser, select link either for jar or jad - phone will start to install application. Note that installing from jad might not work due to missing certificates, etc. In this case, try to install jar file (just select jar-link in html browser).

I have samsung champ gt-c3303 .It cannot run any java supported file what can i do for it ?


Just place a jar files(games or apps) on a memory card. Then just click on the apps or games it will install. Samsung champ will only install below 500 kb/apps or game, if you want to install higher than that just used this code by dialing *#52828378# you will go to Java Test Menu, then go to OTA test, change 500 to 4000 then save. You can now install as much higher than 500 kb but less than 4 mb.
