    <p>I've got a "JSP Document" ("JSP in XML") nicely formatted and when the webpage is generated and sent to the user, some linebreaks are removed.</p> <p>Now the really weird part: apparently the "main" .jsp always gets <em>all</em> its linebreak removed but for any subsequent .jsp included from the main .jsp, linebreaks seems to be randomly removed (some are there, others aren't).</p> <p>For example, if I'm looking at the webpage served from Firefox and ask to <em>"view source"</em>, I get to see what is generated.</p> <p>So, what determines when/how linebreaks are kept/removed?</p> <p>This is just an example I made up... Can you force a .jsp to serve this:</p> <pre><code>&lt;body&gt;&lt;div id="page"&gt;&lt;div id="header"&gt;&lt;div class="title"&gt;... </code></pre> <p>or this:</p> <pre><code>&lt;body&gt; &lt;div id="page"&gt; &lt;div id="header"&gt; &lt;div class="title"&gt;... </code></pre> <p>?</p> <p>I take it that linebreaks are removed to save on bandwidth, but what if I want to keep them? And what if I want to keep the same XML indentation as in my .jsp file?</p> <p>Is this doable?</p> <p><strong>EDIT</strong></p> <p>Following skaffman's advice, I took a look at the generated .java files and the "main" one doesn't have lots of <em>out.write</em> but not a single one writing tabs nor newlines. Contrary to that file, all the ones that I'm including from that main .jsp have lots of lines like:</p> <pre><code>out.write("\t...\n"); </code></pre> <p>So I guess my question stays exactly the same: what determines how tabs/space/linebreaks are included/removed in the output?</p>

    1. COHave a look at the `.java` files that get generated from the JSP by the appserver, that might give you a clue as to why it's making these decisions.

    2. COAre you using `<jsp:include>` or `<% include %>`? Are you specifying content-type headers on any of them? Are the file extensions different?

    3. CO@skaffman: thanks a lot for helping me with this. <jsp:include> everywhere. All files are named ".jsp". The content type is the same on all of them (AFAIK subsequent trials to set the content type are perfectly valid and results in them being ignored so it is not an issue to include .jsp re-setting headers). It's really as if all tabs/newlines were removed from the first .jsp but as if some tabs/newlines were kept from the .jsp included using <jsp:include. But even there: it doesn't seem consistent.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
