Reverse2Servlet

My code for the servlet in Assignment: Servlets-3 Reverse2Servlet seems to be working except when a single quote gets put into the text box and submitted. When that happens the text that gets reversed and sent back is whatever is after the single quote and I am not sure how or whether I need to correct for this situation.
Any Suggestions?

Amber slow down youre giving me a complex

Sorry again I cant help, lets hope the "boss" responds.

Don't worry with all the files associated with Servlets 4 and 5 I am sure to slow to a crawl real quick.

I feel like I have tried everything to make this Servlet work when a single quote gets entered but I am all out of ideas.
Do I even need to worry about whether they enter the single quote or Not? If so, any suggestions on how to proceed?

Amber I'll try and look at it this weekend, we have 3 day one

A servlet will interpret a single quote as a marker for the beginning or the end of the string in the textbox. You need to find a way for the servlet to recognize the single quote as just a single quote and not a marker. (I don't know what the technical word is so I am using the word "marker".)
There is a class in com.javaranch.common.* that has a method that is useful for doing this. If you don't want to use that class, there is a class in the regular Java api that has a method that does the same thing.

Thanks Daniel,
I got it to work with the single quote

But it took me a long time to figure out what to convert the single quote to so the browser could read it correctly.

Maybe something like this will help:
static String validHTML( String original )
{
int ol = original.length();
StringBuffer new = new StringBuffert( ol );
char next;
for ( int i = 0 ; i < ol ; i++ )
{
next = original.charAt(i);
if ( next == ''' )
{
new.append( "&$#39");
}
else if
" other difficult cases etc."
}
