Mixing Signed and Unsigned Code explains a warning dialog that is raised Starting with Java SE 6 Update 19, a new warning dialog is displayed when a program contains both signed and unsigned components in Java SE 6 Update 19 release (or later). (see Mixing Signed and Unsigned Code for more detail) Even when all the client side jars are signed, you might users may still see this dialog when running nexaweb Nexaweb applications . This is because of the way nexaweb Nexaweb plugin jars are packaged and used. To prevent this the dialog, you need to unpack, rearrange, re-pack and then sign the plugin jars.

Here are the steps -:

Explode Unjar the plugin jar file
For eg. PluginDataFramework.jar, you this will getcreate:
   plugin.xml (Keep keep this)
   PLUGIN-INF (Keep keep this)
   lib - PluginDataFramework-classes.jar (keep this), ognl-2.6.7.jar (Delete this. Not delete this - it is not required as it is already in your NexawebClient.jar)
Repackage inner classes jar files in the lib folder
a. Unjar inner classes jarfiles
    For eg. PluginDataFramework-classes.jar, you will get:
META     META-INF (delete this)
com   com\nexaweb\plugin\data directory structure with classes
b. Create a folder, nxPlugin-<plugin class name> inside the exploded folder
For eg. PluginDataFramework-classes, you will have:
com    com\nexaweb\plugin\data directory structure with classes
nxplugin    nxplugin-PluginDataFramework folder
c. Move plugin.xml to the nxPlugin-<plugin class name> folder
d. jar plugin classes into plugin classes jar file
For eg.      Following the example: PluginDataFramework-classes.jar
e. Sign the inner plugin classes jar files
f. Remove exploded folder
If <ui-test> is set to true in nexaweb-client.xml, it uses the debug/plugin classes-debug jar files . You need to repeat same process as with plugin classes jar fileswill be used. Repeat the process above for the debug versions of the jar files..
Jar the main plugin folder.
Create a pre-loaded folder inside in WebContent/WEB-INF/client/plugins
Copy the repackaged jar files into the pre-loaded folder and delete the jars from plugins

Add tag mapping for plugin.xml in your nexaweb-client.xml.
For eg.:

Code Block

title	nexaweb-client.xml

<client-tag-mapping>
	<tag-map-file>classpath://nxplugin-PluginDataFramework/plugin.xml</tag-map-file>
</client-tag-mapping>

Here is a sample
