Passing a variable from a jsp page to Java code and back to jsp page.
I am new to Java programming but I have some experience in programming.
<display:column titleKey="testOrder.voucher" width="110">
${testOrder.voucherNumber}
</display:column>
${testOrder.voucherNumber} prints a string made of a combination of letters and numbers (ABC1234).
I want a way to split the string ABC1234 and only print the number 1234 in the input box.
Also, I want the user to only be able to write numeric values in the input box.
Thanks for the help.
Re: Passing a variable from a jsp page to Java code and back to jsp page.
Just declare it. String x = " ";
String y = " ";
String z = " ";
Then write it out. So the results being z. You would re-type the method or formula in to split ABC and 1234 to give the results as...this would then be in jsp. And they're using probably html to mark up a page. I know C++ is similar to Java. But the same approach. This would be the conversion part. Write it in the program in Java.
