    <p>Here's my problem.</p> <p>I need to set up a process, preferably with jstl/jsp, that depending on what a client enters in a URL parameter, a certain URL will be returned, with the same parameters passed on, and opened via javascript pop up function.</p> <p>Problem I am having, is that the choose statement is not finding one of the parameters unless its one of the beginning parameters. (Now your thinking, 'huh?')</p> <p>The list of parameters the client is passing, looks like this...</p> <pre><code>?name=personsname&amp;email=personsemail&amp;tmplatecde=7&amp;legalid=20266998&amp;photoURL=%2Favmedia%2Fweb%2Findex%2F25505893822%2EJPG&amp;agentNumber=047666&amp;FWSType=FR&amp;des=,+CLU%AE,+ChFC%AE&amp;postto=thenetwork.nmfn.com&amp;agentnumber=047666&amp;formname=FWSContactForm2&amp;attr=FRSite </code></pre> <p>Out of that parameter, I only really need the 'formname.' However if I put the query string in like that, which is what the client is expecting to do, it won't find the formname. Move the formname parameter to before the 'name' parameter, it works. </p> <p>At my company we built a custom JSP tag that can simply take that query string and attach it to a specified URL, but to determine that URL I need to check what the formname is equal too.</p> <p>Does anyone have any ideas of an appropriate way to parse the string to get that formname value?</p> <p>So far, the code that I have that matters to this issue is</p> <pre><code>&lt;c:choose&gt;&lt;c:when test='${param.formname == "FWSContactForm2"}' &gt; </code></pre> <p>Any help would be greatly appreciated.</p>

    1. COTry shifting the formname parameter to the left and test until it works. Maybe the characters in one of the other parameters is messing things up?

    2. COBy the time you get to JSTL and your JSP page, the query string has already been taken apart by the servlet container. You should debug by figuring out what all the parameters actually are, and that might tell you what part of the URL is syntactically invalid and causing the servlet container to miss the trailing parameters.

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.
