We have a spring-enabled java desktop application started through Java Web Start. The JNLP is properly created and downloaded but in the server http logs we see 404 errors on download on some unexisting libraries (<code>org.springframework.core.jar</code> and <code>org.springframework.beans.jar</code>): <pre><code>127.0.0.1 -

But I can't figure out why. Any suggestion? Edit: It's probably worth noting that this behavior is not a blocking issue: the app works correctly. However, the server log pretty quickly fills with 404s. Here is the JNLP file downloaded from the server. I'm pretty confident it is ok (checked it with JaNeLA already), and it sure doesn't include the 404'd libs. <pre><code><?xml version="1.0" encoding="utf-8"?> <jnlp spec="1.0+" codebase="http://localhost:8180/akct/client/" href="management.jnlp"> <information> <title>AKCT 1.0.2-SNAPSHOT</title> <vendor>VENDOR</vendor> <description kind="one-line">NewSoft AKCT</description> <offline-allowed/> <shortcut> <desktop/> </shortcut> </information> <update check="always" policy="always"/> <security> <all-permissions/> </security> <resources> <j2se version="1.5+" initial-heap-size="64m" max-heap-size="512m" /> <property name="jnlp.versionEnabled" value="true" /> <property name="sun.java2d.d3d" value="false"/> <property name="language" value="en"/> <jar href="AKCT-Client-Base.jar" version="1.0.2-20111104.160339-19" main="true"/> <jar href="AKCT-Model.jar" version="1.0.2-SNAPSHOT"/> <jar href="Commons-Model.jar" version="0.1.91-AKCT-p2-20111103.145743-8"/> <jar href="slf4j-log4j12.jar" version="1.6.1"/> <jar href="slf4j-api.jar" version="1.5.11"/> <jar href="log4j.jar" version="1.2.16"/> <jar href="spring-security-core.jar" version="3.0.5.RELEASE"/> <jar href="spring-expression.jar" version="3.0.5.RELEASE"/> <jar href="spring-core.jar" version="3.0.5.RELEASE"/> <jar href="spring-asm.jar" version="3.0.5.RELEASE"/> <jar href="commons-logging.jar" version="1.1.1"/> <jar href="spring-context.jar" version="3.0.5.RELEASE"/> <jar href="spring-aop.jar" version="3.0.5.RELEASE"/> <jar href="aopalliance.jar" version="1.0"/> <jar href="spring-beans.jar" version="3.0.5.RELEASE"/> <jar href="spring-tx.jar" version="3.0.5.RELEASE"/> <jar href="aspectjrt.jar" version="1.6.8"/> <jar href="aspectjweaver.jar" version="1.6.8"/> <jar href="xstream.jar" version="1.3.1"/> <jar href="xpp3_min.jar" version="1.1.4c"/> <jar href="commons-lang.jar" version="2.6"/> <jar href="commons-io.jar" version="2.0.1"/> <jar href="commons-collections.jar" version="3.1"/> <jar href="hibernate-jpa-2.0-api.jar" version="1.0.0.Final"/> <jar href="javassist.jar" version="3.12.0.GA"/> <jar href="annotations.jar" version="1.3.9"/> <jar href="joda-time.jar" version="1.6.2"/> <jar href="jaxrs-api.jar" version="2.1.0.GA"/> <jar href="resteasy-jaxrs.jar" version="2.1.0.GA"/> <jar href="scannotation.jar" version="1.0.2"/> <jar href="jsr250-api.jar" version="1.0"/> <jar href="activation.jar" version="1.1"/> <jar href="commons-httpclient.jar" version="3.1"/> <jar href="commons-codec.jar" version="1.2"/> <jar href="httpclient.jar" version="4.0.3"/> <jar href="httpcore.jar" version="4.0.1"/> <jar href="jcip-annotations.jar" version="1.0"/> <jar href="swingx-core.jar" version="1.6.2-2"/> <jar href="ehcache-core.jar" version="2.3.1"/> <jar href="tinylaf.jar" version="1.4.0"/> <jar href="Commons-Model.jar" version="0.1.91-AKCT-p2-SNAPSHOT"/> <jar href="hibernate-entitymanager.jar" version="3.6.0.Final"/> <jar href="hibernate-core.jar" version="3.6.0.Final"/> <jar href="antlr.jar" version="2.7.6"/> <jar href="dom4j.jar" version="1.6.1"/> <jar href="hibernate-commons-annotations.jar" version="3.2.0.Final"/> <jar href="jta.jar" version="1.1"/> <jar href="cglib.jar" version="2.2"/> <jar href="asm.jar" version="3.1"/> </resources> <application-desc main-class="be.goca.akct.core.domain.swing.Management"> <argument>central1</argument> <argument>1.0.1</argument> <argument>application.levelCode=CL;application.locationIdentifier=1;application.locationName=central1;application.locationAppServer=http://localhost:8180/akct/services;application.parentLevelCode=;application.parentLocationIdentifier=;application.parentLocationName=;application.parentLocationAppServer=;application.externalLibPath=C:/projects/GOCA/application/AKCT-Rules/src/test/resources;application.rulesLibraryPrefix=AKCT-RuleTest-v;application.fallbackAppServer=http://localhost:8180/akct/services</argument> </application-desc> </jnlp> </code></pre>

Guidance

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.
