Noone came across this issue, please help me?

This is not a hexdecimal value, this is double value. If you're willing to see this value in readable format, you must format it.

Thanks for your reply.

When i tried to use your code, 'DecimalFormat' is in java.text package. In J2ME, CLDC doesnot support java.text package, only CDC does.
Then, how can i solve this issue..?

Experts,

Im doing j2me apps, I have a string that i want to convert into double for manipulation. I have a string "49997993357",

when i convert into double like
Double.parseDouble(Balance) ; Double.valueOf(Balance); Double.valueOf(Balance).doubleValue();

Its not converting into double. Im getting hexaDecimal value is 4.9997993357E10.

Im getting value with scientific notation..? How do i get the correct double value from string..?

I m not able to use BigDecimal and NumberFormat of java.text package in J2Me...?

Suggest me any ideas..?

Is there any other method to convert into double value..?

hi,

this is my code for creating a file and write data

try { FileConnection c = (FileConnection) Connector.open( "file:///C:/Documents and Settings/kumar/myTxt.txt", Connector.READ_WRITE); if (c.exists()) { System.out.println("exist"); } else { System.out.println("no exist"); c.create(); OutputStream out = c.openOutputStream(); String userText = text.getString(); out.write(userText.getBytes()); // out.flush(); out.close(); c.close(); } } catch (Exception e) { }

I'm using Sun WTK, the file path as "file:///C:/Documents and Settings/kumar/myTxt.txt". The program executes but i am not able to find the file?


What i made wrong.?

Friends,

I am new to writing and reading a file. I did sample sample by using this link http://wiki.forum.nokia.com/index.php/How_to_write_data_to_a_file_in_Java_ME.

In real devices, file stored in Gallery's Images folder.

Now, I trying in emulator, and did the path like "file://C:/pro.txt". where i can find the file in system? I checked here C:\WTK2.5.2_01\j2mewtk_template\appdb\DefaultColorPhone\filesystem\root1. but there is no file created.


How can i store in emulator and where i can find the path of the text file?

I'm working in the connection, when i receive a string from the server, after getting response.

jus assume that, i have a single string! a string is received and i want to raise a event to my application that a event happens

In java, we use EventObject class, EventManager class, EventListerner to create a custom events..?

how can i do this in ME?

I amdeveloping a JavaME application that will run in the background and monitor events and upon some event match like say at certain specefic time, and on the capture of the event invoke some methods in the application

Is there a way where we can implement such an event listener which will invoke our applications when such an event occurs.

How to raise custom events and handle in J2me.?

I'm using this code for MD5 algorithm for encryption
String cipher = ""; byte[] ab = null; try { MessageDigest md = MessageDigest.getInstance(MessageDigest.ALG_SHA, true); md.update(input.getBytes(), 0, input.length()); System.out.println("in genHash method"); System.out.println("\t" + input); System.out.println("\t" + md); short sh = md.doFinal(input.getBytes(), 0, input.length(), ab, 0); System.out.println("\tsh = " + sh); } catch (CryptoException e) { // TODO Auto-generated catch block e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } cipher = bytesToHex(ab);


Showing error is as

C:\Documents and Settings\kumar\My Documents\NetBeansProjects\J2ME-MD5\source\src\md5\mdsMidlet.java:7: package com.sun.midp.ssl does not exist

Thanks for your reply,

Your CSS doesn't look right: You're missing the dot "." in front of your classes.

I did my css file right by insert '.' before class name, and also value but it doesn't work.

please provide me example of colspan..? what is problem in my code..?

correct it and post here.

kumar.

Thank you very much!!

I tried like this.

//#style defaultTable ADWLtable = new TableItem(3,1); //#style columntitle ADWLtable.set(0, 0, "Title"); //#style columnrow ADWLtable.set(1, 0, ""); //#style columnrow ADWLtable.set(2, 0, "");

In Css, I want to merge these 3 cells into one, so,

columntitle { min-width:75; max-width:75; layout: right; min-height:20; max-height:20; } columnrow extends columntitle { colspan: 2; layout: right; min-height:20; max-height:20; }


but its not works.

please help me?
