org.apache.catalina.LifecycleException：无法启动组件

Question

i am getting this error when starting my tomcat server with my application.

I don't really understand it but if i "clean" in eclipse a few times or if i stop start the tomcat server a few times it somehow works, but then it happens over again if i stop.

any ideas?

Answer 1

First of all, that looks like Pivotal's tc Server rather than Apache Tomcat. tc Server is based on Apache Tomcat but they are not exactlt the same and it always helps to provide the most accurrate information you can.

There is something seriously wrong with your dependencies. Tomcat is detecting the following class heirarchy:

org.bouncycastle.asn1.ASN1EncodableVector ->org.bouncycastle.asn1.DEREncodableVector ->org.bouncycastle.asn1.ASN1EncodableVector

This is a cyclic dependency. In Java it is illegal for A to extend B if B extends A.

Cleaning out your dependencies and ensuring you are using only using one version of the bouncy castle JAR should fix this.

If the problem persists and can be reproduced on a clean install of the latest stable Tomcat 7 release then please do open a bug against Apache Tomcat and provide the web application that demonstrates the issue.
