    <p>My project uses spring and spring-dm for bean/service configuration. When I try to import an old project which also use spring for DI, bean will not be created. </p> <p>An example to make clear,</p> <p>I first define a url-alias in spring-appContext.xml</p> <pre><code>&lt;bean name="xxxx" class="XRegistry" init-method="init"&gt; &lt;property name="webRoot" value="/WebContent"&gt;&lt;/property&gt; &lt;property name="alias" value="/test"&gt;&lt;/property&gt; &lt;property name="cAliasPattern" value="/test/*.do" /&gt; &lt;property name="conConfigFile" value="ddd.xml"/&gt; &lt;/bean&gt; </code></pre> <p>in ddd.xml, I define some controller bean with url like /test/abc.do</p> <p>No errors occur when launching as OSGi framework in eclipse. But when I try to access the URL(/test/abc.do)，"<strong>Unknown OSGi URL</strong>:" is met.</p> <p>The problem really confuses me is I am not clear where to start. My bundle has depended on spring bundles and have appContext.xml and dispatcher.xml. Just a normal spring usage scenario. </p> <p>As spring looks like black box to me, I can only try some other possible reasons I can think, but haven't fixed it till now. Is somebody know how to moniter the spring startup process or helpful logs?</p> <p>Thanks. </p> <p><strong>Edit</strong> when using spring-dm, you need to create a new fragment including log4j.properties to enable logging. This can help u to track spring startuping error.</p> <p>As I explain in the 1st answer, the root cause is found, two choice, </p> <ol> <li>For those bundles exist in both workspace and target platform, increase the bundle's version in current workspace. When error happens , you should also look into the dependency bundles</li> <li>Remove the high version bundles in target platform.</li> </ol>

    2. COYou haven't given anywhere near enough information for anyone to help you. You talk about a "url-mapping". What kind of mapping? How are you trying to access it, and why do you expect it to be available in the first place?

    3. CO@Ryan, I am wondering whether there's a general way to diagnose spring bean creation problem. Regarding my problem, I updated in the question section to make things clear. yes, I access the URL(/test/abc.do) ,and "Unknown URL" is met. From my usage of spring, by defining a validated spring configuration file in bundle and then run the bundle in spring ENV, the spring will handle all backend work. So I expect to access the URL successfully.

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.
