Java异常捕获/抛出

我有以下课程：

BusinessException.java（是需要捕获异常并抛出它的主要异常类）

BusinessExceptionInfo.java

public class BusinessException {

    protected ExceptionResponse exceptionResponse;
    protected String message;

    // getters and setters for these properties
}

public class ErrorResponseItem {

    protected String defaultErrorDescription;
    protected List<String> descriptionVariables;
    protected String errorCode;
    protected SourceSystemFault sourceSystemFault;

// getter and setter methods
}

// SourceSystemFault.java
public class SourceSystemFault {

    protected List<String> calloutParameters;
    protected String errorCode;
    protected String errorDescription;
    protected String operationName;
    protected String serviceName;
    protected String system;
}

ExceptionResponse.java（此类保存异常消息和堆栈跟踪。此类需要使用来自异常的值填充）

如何捕获并抛出BusinessException。我是个新手，需要帮助。

你能解释一下你想要实现什么吗？尝试在soap Web服务中抛出业务异常你读过Java异常教程吗？要捕获的异常在哪里？当您遇到异常时，您希望发生什么？

public class ExceptionResponse {

    protected String exceptionClass;
    protected String exceptionMessage;
    protected List<ErrorResponseItem> errorResponseItems;
    protected String stackTrace;

    // getters and setters for these properties
}

public class ErrorResponseItem {

    protected String defaultErrorDescription;
    protected List<String> descriptionVariables;
    protected String errorCode;
    protected SourceSystemFault sourceSystemFault;

// getter and setter methods
}

// SourceSystemFault.java
public class SourceSystemFault {

    protected List<String> calloutParameters;
    protected String errorCode;
    protected String errorDescription;
    protected String operationName;
    protected String serviceName;
    protected String system;
}

public MyResponse myMethod(MyRequest req)
            throws BusinessException {
}
