OpenSAML bootstrap() 告诉我“InputStream 不能为空”
部署环境:Windows Server 2008、Tomcat 7.0.5、Oracle JRE 1.6。开发环境相同加上 Eclipse Helios。
当我尝试部署使用 OpenSAML 2.3.1 的 Java 应用程序并对其进行实时测试时,它不想运行。查看源代码和堆栈跟踪,似乎 DefaultBootstrap.bootstrap()
最终导致 java.lang.IllegalArgumentException:InputStream 不能为 null
。我在下面包含了完整的堆栈跟踪。
目标部署系统上的软件版本与我的开发盒上的软件版本完全相同,或者至少应该是完全相同,一切都运行良好,但当然我不使用 .war 进行部署。我明显感觉到部署存档中缺少一些 XML 或 DTD 文件,但仅凭这种感觉并不能帮助我修复它。谷歌搜索部分堆栈跟踪也并没有给我带来多大帮助。
我从哪里开始追踪此错误的实际根本原因,以便修复它?

ParsedResponse.java 第 56 行是其构造函数中的 bootstrap() 调用:
private PersedResponse() throws ConfigurationException {
DefaultBootstrap.bootstrap(); // line 56
...
而同一文件中的第 104 行是从外部调用的构造函数调用此私有默认构造函数:
public ParsedResponse(final String samlXML)
throws UnmarshallingException, ConfigurationException {
this(); // line 104
...
Deployment environment: Windows Server 2008, Tomcat 7.0.5, Oracle JRE 1.6. Development environment same plus Eclipse Helios.
When I try to deploy my Java application which uses OpenSAML 2.3.1 and test it live, it doesn't want to run. Looking through the source code and stack trace, it seems that DefaultBootstrap.bootstrap()
ends up causing java.lang.IllegalArgumentException: InputStream cannot be null
. I'm including the full stack trace below.
The software versions on the target deployment system are, or at least are supposed to be, exactly the same as on my development box, where everything runs just fine, but of course there I don't deploy using the .war. I am getting the distinct feeling that I'm missing some XML or DTD file in the deployment archive, but that feeling alone doesn't help me much in fixing it. Googling for parts of the stacktrace also didn't really help me much.
Where do I start tracking down the actual root cause of this error, so I can fix it?

ParsedResponse.java line 56 is the bootstrap() call in its constructor:
private PersedResponse() throws ConfigurationException {
DefaultBootstrap.bootstrap(); // line 56
...
whereas line 104 in that same file is the constructor that gets called from the outside calling this private default constructor:
public ParsedResponse(final String samlXML)
throws UnmarshallingException, ConfigurationException {
this(); // line 104
...

将
openws-1.3.0.jar
添加到部署程序集中就可以了。Adding
openws-1.3.0.jar
to the deployment assembly did the trick.
