Hi,
The following piece of code gives me 2 warnings:
<% if (true) { %>
<html>
<head>
<title>
title
</title>
</head>
<body>
body
</body>
</html>
<% } else { %>
<html>
<head>
<title>
title
</title>
</head>
<body>
body
</body>
</html>
<% } %>The warnings:
1) Duplicate tag (html)
2) Empty block should be documented (twice).I know a workaround for the first warning (simply put the html tag outside the if-statement), but isn’t it possible to make the validator a little bit smarter?
I also know a workaround for the second warning (put /* no problem */ after each { ), or set the validation option (Java > Compiler > Errors/Warnings > Code Style > Undocumented empty block) to ignore in the settings, but this is not really an option for me (I’m using this option in java code with great success).

Im afraid that you will have to turn off the HTML validator or mark that individual file excluded from validation completely to overcome this issue. The HTML validator isn’t aware of JSP logic constructs, like if/else, so it doesn’t see that you only have one resultant tag set… it just sees duplicates
Hi Nipun,
Thanks for your response.
The piece of code I’ve posted is jsp content, placed in a .jsp file.
If I turn off the HTML syntax validator, the warning about the duplicate html tag isn’t going away. If
I turn off the JSP content validator it’s gone (I have tested this multiple times). Is this also a problem
of the JSP content validator? This validator should be aware of JSP logic contructs, or am I missing
something?Have you already looked into my second “warning” problem: Empty block should be documented?
Thanks,
Teun Hoogendoorn
Have you already looked into my second “warning” problem: Empty block should be documented?
I was unable to reproduce the 2nd warning using the code that you have provided. What line are you getting the error at? Can you give me any other example that can be used to reproduce this.
Hi Nipun,
I’m getting the warnings (Empty block should be documented) at line 1 and line 12.
Another example (just one line):
<% if (true) { %><html></html><% } %>
Warning at line 1: Empty block should be documented
This warning only appears if you have the following settings:
1) Window > Preferences > Java > Compiler > Errors/Warnings > Code Style > Undocumented empty block: Warning
2) Turn on the JSP Syntax ValidatorThanks again,
Teun Hoogendoorn.
I have the same problem here! But it’s also a bit strange that he only gives a warning for the <html> tag and not the <head>, <title> and <body> tag.
