Debian5-lenny 配置Hudson时遇到的问题

在Hudson上配置Email时，总是提示“Must issue a STARTTLS command first”，Google了一下，需要在启动时加上参数‘-Dmail.smtp.starttls.enable="true"’，由于我的Hudson是通过apt-get install hudson下载下来的，所以在/etc/default/hudson下配置，输入命令：#vim /etc/default/hudson，然后加上JAVA_ARGS='-Dmail.smtp.starttls.enable="true"'，保存，重启Hudson，命令：#/etc/init.d/hudson restart，试着发一下邮件，结果还是不行，不过这次是提示“Can't send command to SMTP host ....... Case By : trustAnchors parameter must be non-empty ......”，无奈，再次Google，最后终于看到某篇文章，在此贴出原文：

How to fix Java on Debian Lenny

by ARTUR posted on MARCH 26, 2010

This post was previously about getting Amazon ec2 API tools working on Debian Lenny when seeing something like this:

user@computer:$ ec2-describe-instances
Unexpected error:
javax.net.ssl.SSLException: java.lang.RuntimeException: Unexpected error: java.security.InvalidAlgorithmParameterException: the trustAnchors parameter must be non-empty
at sun.security.ssl.Alerts.getSSLException(Alerts.java:208)
at sun.security.ssl.SSLSocketImpl.fatal(SSLSocketImpl.java:1611)

After number of comments it looked as a generic solution to java related problems so I’ve change the title.

Here is how to fix it Java on Lenny:

user@computer:$ apt-get install openjdk-6-jre
mkdir /tmp/java 
cd /tmp/java
wget http://ftp.de.debian.org/debian/pool/main/c/ca-certificates-java/ca-certificates-java_20100412_all.deb
ar xf ca-certificates-java_20100412_all.deb
tar -zxvf data.tar.gz 
cd /usr/lib/jvm/java-6-openjdk/jre/lib/security/ 
mv cacerts cacerts.PREVIOUS 
cp /tmp/java/usr/share/ca-certificates-java/cacerts /usr/lib/jvm/java-6-openjdk/jre/lib/security/cacerts

If you get 404 when running wget go here and download latest package.
