Corda: Error in starting node after upgrade to v1.0 and added Serialization whitelist to META-INF.services - corda

Question

Error message when starting up a corda node.
Exception in thread "main" java.lang.NoClassDefFoundError:

The codes for the plugin:
class testcasePlugin : SerializationWhitelist, WebServerPluginRegistry{
override val webApis = listOf(
Function(::MiscApi),
)
override val staticServeDirs: Map<String, String> = mapOf(
// URL is /web/index
"index" to javaClass.classLoader.getResource("index").toExternalForm(),
// URL is /web/testcase
"testcase" to javaClass.classLoader.getResource("testcase").toExternalForm()
)
override val whitelist: List<Class<*>> = listOf(TransactionBuilder::class.java)
}
The trick to get ride of the error is to delete the 'net.corda.core.serialization.SerializationWhitelist' file from the META-INF.services folder leaving only the 'net.corda.webserver.services.WebServerPluginRegistry' file.
Any idea what went wrong?

Answer 1

You have to split the plugin into two, as follows:
class testcaseWebPlugin : WebServerPluginRegistry {
override val webApis = listOf(
Function(::MiscApi))
override val staticServeDirs: Map<String, String> = mapOf(
// URL is /web/index
"index" to javaClass.classLoader.getResource("index").toExternalForm(),
// URL is /web/testcase
"testcase" to javaClass.classLoader.getResource("testcase").toExternalForm()
)
class testcaseSerializationPlugin : SerializationWhitelist {
override val whitelist: List<Class<*>> =
listOf(TransactionBuilder::class.java)
}
}
