解决tomcat6.0.33 配置SSL时报“No Certificate file specified or invalid file format”异常

 在配置tomcat的SSL双向握手中，由于6.0.33版本中默认启用了APR（APR是通过JNI访问的可移植库，可以提高Tomcat的性能和伸缩性），所以采用传统的配置方式（如下）会报异常；

 

传统的SSL配置：

<Connector port="443" protocol="HTTP/1.1" SSLEnabled="true"
		   maxThreads="150" scheme="https" secure="true"
		   clientAuth="true" sslProtocol="TLS"
		   keystoreFile="conf/keystore/test.jks" keystorePass="111111"
		   truststoreFile="conf/keystore/test.jks"   truststorePass="111111"

 

 

 

异常如下：

2011-10-27 9:26:03 org.apache.coyote.http11.Http11AprProtocol init
严重: Error initializing endpoint
java.lang.Exception: No Certificate file specified or invalid file format

 解决办法是采用下面的配置：

<Connector port="443" protocol="org.apache.coyote.http11.Http11Protocol" SSLEnabled="true"
		   maxThreads="150" scheme="https" secure="true"
		   clientAuth="true" sslProtocol="TLS"
		   keystoreFile="conf/keystore/testpsira.jks" keystorePass="111111"
		   truststoreFile="conf/keystore/testpsira.jks"   truststorePass="111111"

其实就是将protocol="HTTP/1.1"替换为protocol="org.apache.coyote.http11.Http11Protocol"，问题得以解决；

APR给Tomcat的性能提升起到很大作用，建议配置APR方式。

 

题外话：

如果辨别Tomcat是否采用APR：

启动Tomcat时，如果采用APR，日志中会有如下信息：

信息: APR capabilities: IPv6 [true], sendfile [true], accept filters [false], random [true].

 

如果没有采用APR，启动时则显示类似的信息：

信息: The APR based Apache Tomcat Native library which allows optimal performance in production environments was not found on the java.library.path: ....后面省略

 

Tomcat6.0.33版本自动集成了APR，之前的版本没有集成，需要手工配置，网上搜索会有很多这方面的教程。
