Hi All,
I am writing an application using J2ME.
The concept of the application is to read/write a book from the mobile phone.

I am able to write books with page numbers.
When i try to have chapter numbers, i encounter problems with insert/delete chapters.

Could anyone point me to the right direction towards efficient book writing sample code or pointers from the mobile phone?

Please advice,
Thanks,
Vijay.C

Storing book page by page:
title_chapterNumber_pageNumber

title_1_1
title_1_2
title_2_3
..
..
title_20_100

Now i want to insert a new chapter between chapter 1 and chapter 2.
title_1_1
title_1_2
title_2_3<--NEWLY INSERTED CHAPTER
title_3_4<-- original chapter 2
..
title_20_100
title_21_101

for me to rename the RMS file,
it takes abt nearly 15mins for 100 files on the real device.

I would like to know if there is any better/effecient way to do these operations.

THanks,
Please advice.

If your data is large it will take time.There many ways for changing rms.
One of them is take all the values from rms and store it in to Vector and delete the rms.then do the changes whatever you want in vector now create new Rms with same name you have created previously then save all the vector data in rms .Try this and let us confirm how its working

Do u think that writing huge amount of data to RMS is the efficient way. I commit that writing to RMS is much speedy then writing to filesystem but still i oppose that writing huge amount of data to RMS is not an efficient thinking.

Well anyways as anshu already suggest u take the funda of vector and deleting RMS is quite a good approach. Insert ur data at the desired place according to ur requirement and then copied to RMS..

check and reply..

Hi

You can add or delete the chapters in RMS as you required. For this you need to do store the sequence of chapters and chapter names or titles in New RecordStore which links to Content Of Chapters. So you need not to manipulate all the recordstores just change in the link of one record store which is small and efficient.
