我是新來的StackOverflow上如此，喜再次=）的InvocationTargetException Web服務使用耶拿和AXIS
我使用耶拿語義Web框架，顆粒裏森納，Eclipse IDE中（在Linux機器上）和炫技OSE來存儲我的圖表。我還使用Protege Editor =）創建了我的本體。
我正在使用SOAP處理客戶端 - 服務器應用程序，我編寫了一個讀取基本模型的過程，通過使用pellet應用推理並將整個推理模型寫入臨時owl文件，然後，另一個過程讀取推理模型並將其存儲在Virtuoso中，這樣我就可以使用Python客戶端通過Virtuoso的SPARQL端點進行查詢。
的問題是，當我調用該調用生成有理有據的模型程序的Web服務，我得到這個消息（在這個問題的最後完整的堆棧跟蹤）
AxisFault
faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException
faultSubcode:
faultString: java.lang.reflect.InvocationTargetException
faultActor:
faultNode:
faultDetail:
{http://xml.apache.org/axis/}hostname:leia
這是慣例生成合理的模型，並且它是拋出異常的那個模型。
public InfModel reasonOverModel(String path) {
Model emptyModel = ModelFactory.createDefaultModel();
// Pellet instance
Reasoner reasoner = PelletReasonerFactory.theInstance().create();
InfModel model = ModelFactory.createInfModel(reasoner, emptyModel);
try {
InputStream in = FileManager.get().open(path);
model.read(in, "");
} catch (Exception ex) {
// TODO: log with log4j
ex.printStackTrace();
return null;
}
return model;
}
它讀取來自「路徑」的基礎模型，它是運用推理過它，但它沒有返回，我的catch子句沒有趕上那個例外，我不知道爲什麼。這似乎是一個軸心問題。
任何想法，線索或建議？ 非常感謝 來自加拉加斯委內瑞拉 ---------------------------- Complete Stacktrace Here ------ -----------------------

編輯1月19日：
我也嘗試從Tomcat 7到tomcat一切移動6.0.35 as @RakeshPatel建議在下面，但仍然得到相同的異常。
我一直在閱讀有關InvocationTargetException，它包裝其他異常，所以，我捕獲它的客戶端，並通過使用getCause（）方法得到原因，但它返回null。奇怪的是，因爲我調試了它，它似乎正在執行所有的try塊，但它永遠不會到達return語句。
任何線索或建議？
