My system: Ubuntu 9.10. Eclipse 3.5.1 with Java EE 1.2.1 (manual install - NOT from synaptic). Web Developer Tools 3.1.1
I ve recently adopted someone else s code (a Dynamic Web Project), and run into lots of errors, warnings and incorrect syntax highlighting in Eclipse. I ve narrowed it down to these 4 lines of code (create a new Dynamic Web Project, and then a new JSP page, and put this in the body):
${(1<2)? "" : "no"}
<%for (int i = 0; i < 5; i++) {%>
<div>${5}</div>
<%}%>
Errors / Warnings / Incorrect syntax highlighting
line1: yellow warning line under < : Invalid character used in text string (${(1<2)? "yes" : "no"}).
line2: red error line under f : Multiple annotations found at this line: 1) Syntax error, insert "Finally" to complete TryStatement. 2) Syntax error, insert "}" to complete ClassBody
line2: red error line under ) : Syntax error on token ")", try expected after this token
line3: yellow warning line under div : No end tag (/div).
line3: yellow warning line under < of closing div: Multiple annotations found at this line: 1) Invalid character used in text string (${5} <%}%>). 2) Invalid character used in text string (${5} <%}%>).
line3: /div is black and purple (for scriptlet code?) instead of green for HTML code
line4: The opening and closing scriplet tags <% and %> are black instead of orange
The page works as expected in a browser: you get 5 five times. If you change the empty quotes on line 1 to "yes" then save, close the file in the editor, r click it in the project explorer > validate, then re-open it: all errors / warnings / incorrect syntax highlighting disappear, except the first one (invalid character). This is incredibly irritating. Any thoughts would be greatly appreciated.
