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

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：

Xml代码


< 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：

Java代码


2011 - 10 - 27 9 : 26 : 03 org.apache.coyote.http11.Http11AprProtocol init

严重: Error initializing endpoint

解决办法是采用下面的配置：

Xml代码


< 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：

Python代码


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：

Python代码


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
