    <p>I'm writing an OSGI bundle using the javax.script package and am having some issues getting Felix to load the package correctly. When attempting to start the bundle, I'm getting:</p> <p>Failed bundle start for org.plugin.script.plugin-scripter [2]: org.osgi.framework.BundleException: Unresolved constraint in bundle 2: package; (package=javax.script)</p> <p>which I think happens when we try to reference a package which isn't correctly loaded into the bundle. I'm fairly certain this is down to the fact that javax.script is only bundled into the JDK starting 1.6 and for some reason Maven is building using something else. So far I've:</p> <p>a. Set the necessary import in my Maven POM for Felix by:</p> <pre><code>&lt;plugin&gt; &lt;groupId&gt;org.apache.felix&lt;/groupId&gt; &lt;artifactId&gt;maven-bundle-plugin&lt;/artifactId&gt; &lt;extensions&gt;true&lt;/extensions&gt; &lt;configuration&gt; &lt;instructions&gt; &lt;Export-Package&gt;org.plugin.script&lt;/Export-Package&gt; &lt;Private-Package&gt;org.plugin.script.*&lt;/Private-Package&gt; &lt;Bundle-Activator&gt;org.plugin.script.ScripterPlugin&lt;/Bundle-Activator&gt; &lt;Import-Package&gt;!*,javax.script,org.osgi.framework;version="1.3.0",javax.naming,javax.naming.spi&lt;/Import-Package&gt; &lt;Embed-Dependency&gt;!org.apache.felix*;scope=compile|runtime;inline=false&lt;/Embed-Dependency&gt; &lt;Embed-Transitive&gt;true&lt;/Embed-Transitive&gt; &lt;Embed-Directory&gt;dependency&lt;/Embed-Directory&gt; &lt;Embed-StripGroup&gt;true&lt;/Embed-StripGroup&gt; &lt;_failok&gt;true&lt;/_failok&gt; &lt;/instructions&gt; &lt;/configuration&gt; &lt;/plugin&gt; </code></pre> <p>b. Set the Maven compiler to 1.6 since that's the earliest we get javax.script</p> <pre><code>&lt;plugin&gt; &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt; &lt;artifactId&gt;maven-compiler-plugin&lt;/artifactId&gt; &lt;version&gt;2.0.2&lt;/version&gt; &lt;configuration&gt; &lt;source&gt;1.6&lt;/source&gt; &lt;target&gt;1.6&lt;/target&gt; &lt;/configuration&gt; &lt;/plugin&gt; </code></pre> <p>c. Not even sure if this makes a difference but I set Felix's framework properties (in their config.properties) to 1.6.0 and included the javax.script export. TBH I'm not sure about this one but figured I'd take a shot.</p> <pre><code>org.osgi.framework.system.packages=org.osgi.framework; version=1.3.0, \ [lots of stuff in between] javax.script; \ version="1.6.0" </code></pre> <p>Still nadda tho. What else did I miss ?</p>

    1. COJust a random hint - it looks like the error is happening when you attempt to load the bundle, so have you checked that your *execution* platform is Java 1.6?

    2. CO@Stephen Thanks for the hint but that was the first suspicion. I've actually removed all versions except for 1.6 so I don't think that's it.

    3. COAh new developments. The manifest tells me that the javax.script package was in Export-Package (under the uses:) and Import-Package but *also* in the Ignore-Package which is weird because I've never set it as such.

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.
