No more 'unable to find valid certification path to requested target'

ideame — Tue, 09 Feb 2010 06:55:00 GMT

From: http://blogs.sun.com/andreas/entry/no_more_unable_to_find

Some of you may be familiar with the (not very user friendly) exception message
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

when trying to open an SSL connection to a host using JSSE. What this usually means is that the server is using a test certificate (possibly generated using keytool) rather than a certificate from a well known commercial Certification Authority such as Verisign or GoDaddy. Web browsers display warning dialogs in this case, but since JSSE cannot assume an interactive user is present it just throws an exception by default.

Certificate validation is a very important part of SSL security, but I am not writing this entry to explain the details. If you are interested, you can start by reading the Wikipedia blurb. I am writing this entry to show a simple way to talk to that host with the test certificate, if you really want to.

Basically, you want to add the server's certificate to the KeyStore with your trusted certificates. There are any number of ways to achieve that, but a simple solution is to compile and run the attached program as java InstallCert hostname, for example

% java InstallCert ecc.fedora.redhat.com
Loading KeyStore /usr/jdk/instances/jdk1 .5.0 /jre/lib/security/cacerts
Opening connection to ecc.fedora.redhat.com: 443

Enter certificate to add to trusted keystore or 'q' to quit: [ 1 ]

What happened was that the program opened a connection to the specified host and started an SSL handshake. It printed the exception stack trace of the error that occured and shows you the certificates used by the server. Now it prompts you for the certificate you want to add to your trusted KeyStore. You should only do this if you are sure that this is the certificate of the trusted host you want to connect to. You may want to check the MD5 and SHA1 certificate fingerprints against a fingerprint generated on the server (e.g. using keytool) to make sure it is the correct certificate.

If you've changed your mind, enter 'q'. If you really want to add the certificate, enter '1'. (You could also add a CA certificate by entering a different certificate, but you usually don't want to do that'). Once you have made your choice, the program will print the following:

...

Added certificate to keystore 'jssecacerts' using alias 'ecc.fedora.redhat.com-1'

It displayed the complete certificate and then added it to a Java KeyStore 'jssecacerts' in the current directory. To use it in your program, either configure JSSE to use it as its trust store (as explained in the documentation) or copy it into your $JAVA_HOME/jre/lib/security directory. If you want all Java applications to recognize the certificate as trusted and not just JSSE, you could also overwrite the cacerts file in that directory.

After all that, JSSE will be able to complete a handshake with the host, which you can verify by running the program again:

% java InstallCert ecc.fedora.redhat.com Loading KeyStore jssecacerts
Opening connection to ecc.fedora.redhat.com:443
Starting SSL handshake
No errors, certificate is already trusted Server sent 2 certificate(s): 1 []

Enter certificate to add to trusted keystore or 'q' to quit: [1] q KeyStore not changed

PowerCenter 安装数据库配�|�的问题

ideame — Fri, 30 May 2008 08:20:00 GMT

安装了几�ơ老是启动有问题：

The service did not start due to the following error: Unable to connect to the repository isaservice on database jamax.. Check the log for more information.

node01

或�?br />The service did not start due to the following error: DataBase error: [IBM][CLI Driver][LU62SPM] SQL30070N 不支�?"Unsupported function for SPMDB connect" 命��o�?SQLSTATE=58014 sqlstate = 40003 Database driver error...

DOM_10055 Unable to start service process [isaservice] on node [node01].
SPC_10013 Process for service isaservice failed to start.

原来怀疑是安装的问题，后来才发现是因�ؓ元数据库和源数据的连接错误地讄��成同一个数据库�Q�造成元数据库损坏造成的。出错后试了几种办法都不行，只能重新再装�Q�原来的元数据就没法用了�Q�这是一个很严重的后果！正确的做法应该如下（本机�Q�：

1. 讄��元数据仓库：

Database URL 格式是HOST_NAME:PORT_NAME�Q�如果用的是默认端口那么只需要填HOST_NAME��可以了�?br />Database user ID: 填一个有��理员权限的用户�Q�sys好像不行�Q�可以用system�Q?br />Database service name: 填全局数据库名, 对应下面的SERVICE_NAME

    (CONNECT_DATA =

      (SERVICE_NAME = informatic.jamax)

2. 新徏源数据库的知识库�Q�Repository �Q�配�|��?br />

�q�里2的数据库配置应该是连接源数据库的�Q�如果设�|��ؓ1的配�|�就会出错�?br />

�Ҏ(gu��)��|�上的一些资料，按照如下步骤

首先��?span style="font-family: Times New Roman,serif;">Subversion安装目录bin\下面的两个文�Ӟ��mod_authz_svn.so�?span style="font-family: Times New Roman,serif;">mod_dav_svn.so复制�?span style="font-family: Times New Roman,serif;">Apache安装目录modules\目录下�?br />
扑ֈ�Apache安装目录下的conf目录�Q�用文本�~�辑器打开httpd.conf�Q�找��C��下两行：

#LoadModule dav_module modules/mod_dav.so
#LoadModule dav_fs_module modules/mod_dav_fs.so

��每行前面的注释�W?#"��L��。再在所有LoadModule语句的最后添加一下几行：

#SVN LoadModule dav_svn_module modules/mod_dav_svn.so LoadModule authz_svn_module modules/mod_authz_svn.so DAV svn SVNParentPath "E:/svnrepos"

但是使用启动��试一直有错，�q�回

Syntax error on line 143 of C:\apache\conf\httpd.conf: API module structure 'dav_svn_module' in file C:\apache\modules\mod_dav_svn.so is garbled - perhaps this is not an Apache module DSO?
