    <p>I am currently utilizing CF session management and have been investigating transitioning to utilizing J2EE session management. In my attempts to do so, ajax requests made ( when CFsession management is set to use J2EE sessions ) to CF cfc remote methods fail the verifyclient authorization. The code below works when session management uses CF session management.</p> <p>My assumption is that the _cf_clientid is no longer the correct value to pass to the remote method - as it is generated using cfid and cftoken.</p> <p>How do I successfully implement J2EE session management and utilize remote cfc methods with verifyclient? Or can it not be done? Using CF tag cfajaxproxy is not an option.</p> <p>The example code below demonstrates how to use jQuery ajax to call a remote cfc method with verifyclient='true', even though CF documentation indicates that the use of cfajaxproxy is required. This is not the case. (Thanks to Ray Camden and DWMommy. ) This leads me to believe that there may also be a work-around to implement a similar method for verifying a client when using J2EE sessions.</p> <p>Thanks in advance!</p> <pre><code>&lt;script src="/plugins/jquery-1.7.2.min.js" type="text/javascript" language="Javascript"&gt;&lt;/script&gt; &lt;cfajaximport /&gt; &lt;script&gt; $(function() { $.ajax({ url: 'test.cfc', type: 'get', dataType: 'json', data: { method: 'sayHello', yourname: 'Foo' ,_cf_clientid: _cf_clientid }, success: displaySearchResults }); }); &lt;/script&gt; &lt;script&gt; function displaySearchResults(res){ $('#searchResults').html( res ); } &lt;/script&gt; &lt;div id="searchResults"&gt;&lt;/div&gt; </code></pre> <p>test.cfc</p> <pre><code>component{ remote any function sayHello ( string yourname = 'anonymous') returnformat='JSON' verifyclient='true'{ return 'Hello ' &amp; arguments.yourname; } } </code></pre>

    1. COWhat is stored in `_cf_clientid`? Can you show us an example? I'm assuming the `cfid` `cftoken` combination. When using J2EE sessions with ColdFusion the session identifier becomes `jsessionid`. You might need to change your code to use that instead.

    2. COYou are correct, the _cf_clientid is generated with the combination of cfid and cftoken. This is why this value has no meaning when using J2EE session management. It is generated regardless with the Application.cfc setting, this.sessionmanagement is set to true. To see an example, create a cf page with the <cfajaximport> tag and view the source. The jsessionid is not available to javascript via cfajaximport and 'hard-coding' the value of session.jsessionid does not appear to work.

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.
