apache velocity 拒绝与处女座合作

Question

我一直在解决一个项目的 virgo 配置问题，但有一个库拒绝合作 - apache velocity。

因此，我的包的清单是（我已经更改或删除了一些内部库的名称）：

Manifest-Version: 1.0
Web-ContextPath: blah
Bundle-ManifestVersion: 2
Bundle-Name: thebundle
Bundle-SymbolicName: blahblah
Bundle-Version: 0.1.0
Bundle-Activator: blah.Activator
Import-Package: mydatasource,
 javax.crypto,
 javax.jms;version="[1.1.0,2.0.0)",
 javax.naming;version=0,
 javax.naming.directory;version=0,
 javax.servlet;version="[2.6.0,2.6.0]",
 javassist.util.proxy;version="[3.15.0.GA,3.15.0.GA]",
 javax.servlet.http;version="[2.6.0,2.6.0]",
 org.hibernate.validator;version="[4.2.0.Final,4.2.0.Final]",
 org.osgi.framework;version="[1.7.0,1.7.0]",
 org.osgi.util.tracker,
 org.slf4j.impl;version="[1.7.2,1.7.2]"
Export-Package: .... (stuff removed)
Bundle-ClassPath: .,
 WEB-INF/classes,
 WEB-INF/lib/velocity.jar <--- THIS IS APACHE VELOCITY
 WEB-INF/lib/blahblah.jar
Import-Bundle: org.eclipse.virgo.web.dm;version="3.5.0.RELEASE";resolution:=optional,
 a bunch of other bundles I've removed

我在长堆栈跟踪结束时收到以下异常：

Caused by: java.lang.ClassNotFoundException: org.apache.velocity.exception.VelocityException
    at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal(BundleLoader.java:501)
    at org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:421)
    at org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:412)
    at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.loadClass(DefaultClassLoader.java:107)
    at org.eclipse.virgo.kernel.userregion.internal.equinox.KernelBundleClassLoader.loadClass(KernelBundleClassLoader.java:135)

我已验证velocity.jar 已在我的包中发布。我对任何其他库都没有任何问题。它似乎看到了一些速度类，但没有看到其他类。我尝试将所有单独的速度包放在 Import-Package 下，但没有效果。我试过苛刻的语言，没有效果。

您必须将包和包导入到您的包中，（在您可以下载速度包并部署到您的拾取文件夹之前）

see this example
