I assume that the problem is you enter text into the textarea and have several new lines eg
paragraph number 1 with some text that might wrap at the edge of the textarea
paragraph number 2 with some different text
paragraph number 3 to end the textarea
This gets stored in MySql, but when the text is redisplayed on the HTML page it appears like this:
paragraph number 1 with some text that might wrap at the edge of the textarea paragraph number 2 with some different text paragraph number 3 to end the textarea
eg missing the line breaks.
To fix this the developer needs to do a search and replace on the text looking for /n (the newline character) and replacing it with <br/> the html line break.
You only want to do this when displaying the text, not when you put it into the database. If you wanted to edit this text again it would have <br/> tags instead of newlines which would look bad. Also if you use something like <bean:write> to write out the text it will try to escape the characters, meaning the <br/> will change into <br/> and not work as line breaks.
I use this taglib http://jakarta.apache.org/taglibs/doc/string-doc/intro.html for doing the replace in the JSP page after the html has been escaped. I use it with JSTL eg
<str:replace replace="NL" with="<br>NL" newlineToken="NL"><c:out value="${content}" /></str:replace>
but you might be able to use it like this (if using struts tags):
<str:replace replace="NL" with="<br>NL" newlineToken="NL"><bean:write name="content" /></str:replace>

Anyway, we have a blog application written in Struts. The user inputs some text, consisting of more than one paragraph. The submit is done using textarea from Struts, not from HTML (I can't explain better, I am not the developer, but I am sure you understand what I mean). Unfortunately at this stage all formating of text (most important paragraph markings) is cleared away; within Mysql the text is one single chunk.
There must be a solution to upload text corectly into a database using Struts, so if there are any paragraphs they are preserved during submit. Any hints?
With many thanks in advance for absolutely any help,
