Answer 1

在Corda 4.0中，财务cordapp已分为两部分，即corda-finance合同和corda-finance-workflow。

由于签名约束方面的工作，（请参见此处：https://docs.corda.net/release-notes.html#signature-constraints），现在可以对CorDapp JAR进行签名了。因此，我们建议为合同和工作流创建单独的JAR，以便工作流可以根据其所依赖的合同而独立发展。

corda-workflows-finance JAR包含财务应用程序的数据库迁移，因此您需要同时安装两个应用程序才能使财务应用程序正常工作。将工作流JAR添加到节点cordapp目录将解决此问题。

可在以下位置找到JAR：https://ci-artifactory.corda.r3cev.com/artifactory/corda-releases/net/corda/corda-finance-workflows/

在Corda 4.0上使用财务cordapp启动节点时无法创建数据源[errorCode = 13ajh5q]
