添加ejb.jar后，我收到此错误
javax.naming.NoInitialContextException: Cannot instantiate class: com.ibm.websphere.naming.WsnInitialContextFactory [Root exception is java.lang.ClassNotFoundException: com.ibm.websphere.naming.WsnInitialContextFactory]
at javax.naming.spi.NamingManager.getInitialContext(NamingManager.java:657)
at javax.naming.InitialContext.getDefaultInitCtx(InitialContext.java:288)
at javax.naming.InitialContext.init(InitialContext.java:223)
at javax.naming.InitialContext.<init>(InitialContext.java:175)
但是如果我在Java控制台应用程序中运行相同的代码，它会被执行，我在控制台中获取值，但是当我通过将它与我的Web应用程序集成来运行相同的代码时，它会抛出我上面提到的错误。 / p>
public String process(String message, int start) {
System.out.println("from process method");

这是我的QueryBuilder.java类。我只在我尝试加载上下文的地方调用此类的进程方法：

int count = 0;

try {
num++;
count = resultSet.getInt("SNO");
ArrayList<InvoiceCustomer> list = new ArrayList<InvoiceCustomer>();
list.add((InvoiceCustomer) bp.toBean(resultSet, InvoiceCustomer.class));
TFinvdtoHandler tfinv = new TFinvdtoHandler();
sRequestItems.add(tfinv
.createTFinvdtoRequest(list));
if (num % 1 == 0) {
xmlToPost = MessageUtil.xmlServiceRequest(
sRequestItems, "TFINVNEW");
logger.debug(xmlToPost);
System.out
.println("**Sending data to TI Plus through EJB Client***"
+ "\n");
finalResult = TIPlusEJBClient.process(xmlToPost, count);
if (!finalResult.equals("Unable to Process")) {
List<ServiceResponse> serviceResponses = MessageUtil
.processResponse(finalResult);
for (ServiceResponse serviceResponse : serviceResponses) {
// System.out.println("**Response Status***"
// +serviceResponse.getResponseHeader().getStatus());
// System.out.println("**Response CorrID***"

MigrationUtil.updateMigrationDataStagingStatus(
table, serviceResponse
.getResponseHeader()
.getStatus(), serviceResponse

serviceResponse.getResponseHeader()
.getDetails().getError()
.toString());
}
