Hello,
I am using Eclipse 3.1 on OS X Tiger, with the MyEclipseIDE plug-in…
My color settings are set as follows:
1. Editor’s background is black.
2. Java code is set to white.
3. HTML tags are blue.
4. JSP delimiters are white.
Wrote a simple JSP file and the closing % for my opening JSP Expression (<%=)
does not appear on the screen, it looks like this:<%@ page import = "foo.*" %> <html> <body> The page count is: <% <%= Counter.getCount() %> > </body> </html>Now, when I just toggled / highlighted the code (in order to paste it in here), I did see it there, but
for some reason or another Eclipse doesn’t recognize the <%= and didn’t even code complete the closing %>.The reason I know it doesn’t recognize it is because I get the following errors and warning:
1. Error:
line 7: illegal start of type: <%= Counter.getCount()
2. Error:
line 11: expected: out.write(“\n%>\n\n </body>\n</html>”);
3. Warning:
line 8: Invalid character used in text string ( %> ).
Am really disappointed by this! This is such a simple piece of code
and it seems like the MyEclipseIDE plug-in doesn’t recognize JSP expressions ( <%= %> ).Has anyone seen / experienced a similar problem?
Please help!!!

It doesn’t recognize it because it’s invalid. You cannot embed expressions inside of scriplets, or scriplets inside of scriplets. To understand why, consider that the <%%> delimiters are used by the JSP compiler to denote “inline the following code” then everything, Java code, between <% and %> is directly inlined into your compiled JSP (Servlet class). If you put <%= blah blah %> in there, you end up with Java code that looks like this in the actual class that is trying to be compiled by the app server:
System.out.println("\t\t\t\t<td>"); <%= Counter.getCount() %> System.out.println("\t\t\t\t</td>");Which as you know is not valid Java. Your code needs to be something like this:
The page count is: <%= Counter.getCount() %>Remember, everything between <% and %> is straight Java code. I think you are mixing up how to use <%%> and <%=%>. <%%> is usually used to include processing code or code that does stuff, and <%=%> is used to insert text into the output of the page, like a toString() on something.
