Hello All,

I would like to replace a particular occurrence of a substring in a string with another substring.

for eg : Given string is : people <tag> help </tag> always

expected string is people <font> help </font> always.

I need to replace the occurrence of <tag> </tag> with <font></font>

help would be appreciated.

Thanks



String htmlTags = "people <tag> help </tag>";
htmlTags = htmlTags.replaceAll("tag","font");

from an article i am reading:

Using beans is a very common practice in JSP application development. This approach is popular because JavaBeans introduces reusability. This is to say, rather than building your own piece of code, you can simply use what other people have written. For example, you can purchase a bean for file upload and start uploading files within 30 seconds.

Some of the IDE's nowadays are spoon feeding. Meaning just click of a button or drag and drop an item will create a code for you. You will not learn if these things will do by your IDE. Infact there are a lot of IDE's out there to choose from. But if you get used to one of these IDE's without learning the basics, you will be dependent on it. Nowadays there are company that uses IDE's of their own(maybe their own product). If you get used to your IDE then, you will find hard time to learn their IDE(if you learn the basics from your IDE).

yeah try to validate first on the client side or you can reformat the date on the server before making query
yeah opener will do.

like:

opener.document.[parentFormName].[elementName].value=document.[childFormName].[elementName].value
if you want to do that you will have 2 windows and 2 redirects.
one will redirect a window that will open you page and then it will redirect again to the original page.
