Checked the parameter values passed using a document.write() in javascript file… values were passed correctly including white space in text string. Something about my request object seems to have caused loss of white space …. no problem. I have a fix.

Thanks.

I didn’t handled anything special for deleting white spaces. It works perfectly.
Can you check the request parameters with some tools(firebug/Live http headers) and ensure the parameter values are passed correctly.?

…
iv. then collect parameter values in .asp page using:
request.form(“productname”)

and

v. … each word:
responseText = replace(request.form(“productname”), “*q*”, ” “)

i. ajax.js code OK to get input string values, e.g., Red Apples

ii. problem occurs during collection of string ‘params’ using request
object in .asp page, –> output like ‘RedApples’. (whitespace lost)

iii. my solution is to add code to ajax.js to replace white space in each value using reg expn like this:

var params = “productname=” + formobj.productname.value.replace(/(\s)/g, ‘*q*’); // use *q* as placeholder for spaces (” “) between words

iv. then collect parameter values in .asp page using
v. and then replace ‘*q*’ with ” ” to restore white space between each word:

Does your .jsp page keep white space between words in string?

thanks for your understanding.

And i haven’t used that function directly in my code. (thats the case of those compilation errors). i am constructing that ArrayList on the flow of my code (that is, it will get String elements from several String arrays and combine it in one ArrayList then convent all to Long array). To use ur code i need to know the exact size of String elements that will not be known initially in my case. Now I found a logic to calculate the array size of the strings used in my application. and using ur logic.

ur explanation is very helpful.

Well.. thanks for your comment..

for array type conversion. don’t know about the BEST way except looping logic.

seems to be your pasted code snippets returns lots of complitation errors and mismatch between your question(integer type) n snippet(long type).
anyway k. when comparing with my method. I would say my method consume lesser execution time in performance wise.
you also using the same loop logic, but the difference is you are storing into arraylist and converting into array. this will take more time while execution.
lets explain clearly.
first, iterate the string array and store it into arraylist.
second, using toArray method converting array list to array by that time compiler converting to specified target type which was specified in toArray argument.

my point is toArray method will internally do some looping process. so your code looks like having two loop’s unnecessarily for just converting array type.

sometimes our java code looks simple but lacks performance when its going to process huge data.

hope you understand it. If not post your doubt.
