i already can read from text file using string tokenizer and store it into the database. now the problem is, after it read line by line... but when it stores it.. it doesn't store the data in orderly format. it jumble up everything without following the sequence like in the text file?
can anyone help me on this? thanks

really sorry about that.

ok, let's get to the point

createDataset() method wants to generate a graph. but it needs values.
StartDate() and EndDate() is the methods to extract out the necessary values to be used in the createDataset(), surely i will need a loop. can anyone help me or guide me on the getting values with the loop into createDataset()?

As you can see that
"public static IntervalCategoryDataset createDataset()" want to get the data and attributes from storeStartDate and storeEndDate methods. i have class files, StartDate and EndDate that contains all the accessor methods. after i have store the relevant attributes, i want to call it out in the "public static IntervalCategoryDataset createDataset()" method to manipulate it.

i hope that my question doesn't confuse you all. hope that you all can guide me on this. Thank you

This is one part of my coding to generate a Gantt Chart.
the problem is how can i convert from my chart.java that i kept the month integer to be put into the calendar in this codes below. as you can see that i retrieve from chart class the start day and the year also. but the calendar, i am not sure how. can anyone guide me on this?

thanks

this is a workable sample i got the net. i want to ask some help on, how to retrieve just the day or the month from the startDate? for example, 2001-01-01... so if i want to display the day, it's going to print out "01". how can i do that? can anyone guide me one this? i tried on the codes that i just bold on. but still got error

yea. i got what you meant. look through it already. thanks alot for the info. now i have small little problem. as everyone know that i am using Stringtokenizer to read the token to token. the problem i tried how to embed the SimpleDateFormat into StringTokenizer to read it into day, month, year but fail. can anyone guide me on this?


and another update is, the user that pass me the text file successfully grab it without have the day together the date
so the text file will be read in this way

Testing,12/15/06,12/15/06

so this will be the new type of data that i have to read. another issue is, can i use StringTokenizer to start reading only from the 2nd line because the 1st line is just the header of the file??

thanks alot guys. for your help. really appreciate it

I have a text file that shows like this in every row

Testing,Fri 12/15/06,Fri 12/15/06,0 hrs


i will be using a delimiter to tokenized it by the symbol " , ". the problem now is the text files contain the day and date together as one attribute. how can i cut the day off and just read the date and split the dates into month/day/year? so that i can generate the gantt chart using this values?

can anyone help me on this? Thanks

The one that i highlighted, before that it was a hard code whereby i specific the location of the file. Now i allow the user to browse the file that wanted to be uploaded to the server. I declared in italic. the bold would the value of the parent class inherit into an object and stored the value after executing the method

hope that you all don't if my explanation is quite confusing

Thanks alot.
