Hello,
I'm developping a feature for a plugin and in my feature I create an
Install handler class in order to execute some code at the plugin
installation.
The MyInstallHandler class and the plugin installation is correctly
executed...
Now, I modify the MyInstallHandler class and I need now some externals jar
which are dom4j-1.6.1.jar and jaxen-1.1-beta-6.jar : I include them into
the Java Build Path property project and I add them into the Binary Build
of the Build tab of feature.xml.
But when I install my plugin, there is an error :
java.lang.NoClassDefFoundError: org/dom4j/io/OutputFormat
at java.lang.Class.getDeclaredConstructors0(Native Method)
at java.lang.Class.privateGetDeclaredConstructors(Unknown Source)

Classes are not found...
Have I missed something into the feature configuration ?
Greats for your help...

Thanks for your help... But I have the same error...
I do the following things :
* Within the plugin project :
As you says, I add the two jars within the plugin project like :
- within the Runtime tab, I add dom4j-1.6.1.jar and jaxen-1.1-beta-6.jar
into the classpath.
- within the Build configuration, I select the two jars into the Binary
Build
Thus, the MANIFEST.MF has a Bundle-ClassPath like :
Bundle-ClassPath: lib/dom4j-1.6.1.jar,
lib/jaxen-1.1-beta-6.jar,
.,
* Within the feature project, the organization is :
myplugin.feature
|- src
|- installhandler
|- MyInstallHandler.java
|- feature.xml
|- build.properties
|- installhandler.jar // it's the jar of MyInstallHandler.java
This feature reference the plugin project (which is added within the
Plug-ins and Fragments tab).
The feature.xml file is :
<feature
id="myplugin.feature"
label="myplugin.feature"
version="1.0.1"
provider-name=""
plugin="myplugin">
<install-handler library="installhandler.jar"
handler="installhandler.MyInstallHandler"/>
<description>
My plugin
</description>
<copyright>
</copyright>
<license>
Yes, you agree.
</license>
<requires>
<import plugin="org.eclipse.ui"/>
<import plugin="org.eclipse.core.runtime"/>
<import plugin="org.eclipse.core.resources"/>
<import plugin="org.eclipse.debug.core"/>
</requires>
<plugin
id="myplugin"
download-size="0"
install-size="0"
version="1.0.1"/>
</feature>
I don't know why it's not run... and why classes are not found...
Thanks

When the plug-in is installed, does it still contain the jar files? That
is, does the installed plug-in have a lib/ directory, and are
dom4j-1.6.1.jar and jaxen-1.1-beta-6.jar present in that directory?
