我在Tomcat 7上开发webapp.在我的本地版本的Tomcat 上一切正常,但是当我在生产服务器上部署它时,它会抛出这个异常.

当我尝试FopFactory.newInstance();(来自Apache FOP 1.0)时抛出错误.之后,它试图LogFactory.getLog(FopFactory.class);.它logClass.getConstructor(logConstructorSignature);被称为,其中logConstructorSignature包含一个String.class.(至少在我的本地机器上)
try …我有第三方jar(我无法改变)使用java.beans.Introspector,java.beans.BeanInfo和java.beans.PropertyDescriptor.
如何在我的Android应用程序中使用该jar？
它无法Introspector从第3方jar 加载类(使用):
WARN/dalvikvm(780): VFY: unable to resolve static method 6325: Ljava/beans/Introspector;.getBeanInfo (Ljava/lang/Class;)Ljava/beans/BeanInfo;
WARN/dalvikvm(780): VFY: unable to resolve exception class 962 (Ljava/beans/IntrospectionException;)
WARN/dalvikvm(780): Verifier rejected class Lorg/thirdpartyjar/SomeClass;
org.apache.commons.beanutils.PropertyUtils在Android上有一个方便的花花公子吗？
我似乎无法使用Bean utils在我的Android应用程序,由于对一些依赖PropertyDescriptor,和IndexedPropertyDescriptor.所以我想知道是否有其他选择？
基本上我想做的就是使用一个方法名称作为字符串"someMethod"并将其输入setMethod(anObject, "someMethod", value),就像PropertyUtils它一样; 但不必诉诸于反思的恶作剧......
或者我的双手并列,我需要使用反射？
当我运行应用程序时它会获得异常

我已将所有jar文件放在lib文件夹中.我不知道如何解决这个问题,我的错误在哪里.
