in the run-time workbench, all 4 plug-ins (3 editors and an import/export wizard plug-in) are able to access
PreferencesPlugin.getDefault().getPreferenceStore(). when i bundle up all 6 and install them as plug-ins, i get a
NoClassDefFoundError only for the import/export wizard plug-in. the others work fine like this.
i have included the Preference plug-in in the "Java Build Path / Projects" and it is a required Plug-in Import in the plugin.xml for
all 4 of the plug-ins that use it. i know that the Preference plug-in is being executed at start-up. i have no problems with the 3
editor plug-ins accessing Preference when they are installed. the only one is the import wizard. all 4 get the preference store
exactly in the same manner.
i am stumped. i have tried all sorts of things to get the import wizard to work as a plug-in. any hints or thoughts as to where i
might look next would be greatly appreciated.

Are you sure the class is in the Preferences jar? This is the only
explaination I can come up with.
Also, are you using IStartup? It sounds to me like you don't need to,
but then I don't know your exact situation very well.

the other 3 plugins have no problem accessing methods and retrieving

has been built as an installable plug-in and run from the plugins
directory (vs. from the workspace which works just fine.)
the problem plugin's plugin.xml:
<plugin
id="com.indus.plw.wizard"
name="Localization Import/Export Wizard"
version="1.0.0"
provider-name="INDUS"
class="com.indus.plw.wizard.PPSymSyrImportExportPlugin">

<import plugin="com.indus.plw.preferences"/>
<import plugin="com.indus.plw.translate"/>

........
the wizard's build.properties file:
source.wizard.jar = src/
bin.includes = plugin.xml,\
*.jar,\
icon/,\
wizard.jar
the preferences plugin.xml:
<plugin
id="com.indus.plw.preferences"
name="Preferences Plug-in"
version="1.0.3"
provider-name="INDUS"
class="com.indus.plw.preferences.PreferencesPlugin">

<import plugin="com.indus.plw.core" version="1.0.1"
match="greaterOrEqual"/>
</requires>
<extension
point="org.eclipse.ui.startup"> (and this is getting fired at
su.)
</extension>
....
there doesnt seem to be very many options to influence the classpath of a
plugin. the <requires> tag and <runtime> seem to be about all i can do.
am i missing something here?
there is also the mystery of why the plugins for editors seem to work and
the import wizard does not. i have coded all the plugin.xml and the java
code to access preferencesPlugin the same.
your help here is greatly appreciated,

Willam,
This is indeed a puzzler.
Are there any errors in the .log file? Perhaps there is a plugin
initialization problem with PPSymSyrImportExportPlugin. Are you
implementing IStartup?

the NoClassDefFound error at the bottom of this email was the only error
in the ".log" file. PreferencesPlugin does implement IStartup and is
being started. PPSymSyrImportExportPlugin does not implement IStartup as
there are no functions we need at startup in it.
when i look at the plugin registry, PreferencesPlugin has the little
running man symbol. also, the import/export plugin has the preferences
plugin as a requirement. there are no plugin errors.
we have removed all references to PreferencesPlugin and have hardcoded our
default values for preferneces. now we get the NoClassDefFound error when
it tries to access some functions in a different plugin.
is there someway to check the classpath value for a plugin at run-time?
why would the plug-in's classpath be built correctly for the run-time
workbench, but not when the plug-in is in the plug-in directory?
