我正在使用带有eclipse web工具的Tomcat 6来发布应用程序.当我部署j2ee应用程序时,我通过tomcat日志收到此错误:

我试图在iOS 4.0中的MKMapView上绘制MKPolygon.我有一个NSArray,其中包含自定义对象,包括纬度/经度属性.我有一个代码示例如下:

- (void)viewDidLoad {
    [super viewDidLoad];
    dataController = [[DataController alloc] initWithMockData];
    coordinateData = [dataController getCordData];

    CLLocationCoordinate2D *coords = NULL;
    NSUInteger coordsLen = 0;

    /* How do we actually define an array of CLLocationCoordinate2d? */

    MKPolygon *polygon = [MKPolygon polygonWithCoordinates:coords count:coordsLen];
    [mapView addOverlay: polygon];

}

- (MKOverlayView *)mapView:(MKMapView *)mapView viewForOverlay:(id <MKOverlay>)overlay
{
    MKPolygonView *polygonView = [[MKPolygonView alloc] initWithPolygon: routePolygon]; 
    NSLog(@"Attempting to add Overlay View");   
    return polygonView;
}

我理解的方式是:

1. 我需要创建MKPolygon
2. Ddd是MapView的叠加层
3. 这将转动将触发MKPolygonView的创建.

我的问题是如何获取NSArray(coordinateData)中包含的自定义对象并将这些对象转换为CLLocationCoordinate2d数组,以便Polygon可以解释和呈现？我不确定CLLocationCoordinate2d甚至是一个数组？有人可以对此有所清晰.

使用ANT构建我的Java应用程序时,我不断收到此错误.我已多次尝试使用SQLJDBC.JAR和SQLJDBC4.JAR但不断收到此错误消息.即使在升级到sqljdbc4.jar之后,我仍然完全没收到这个错误.

[javadoc] java.lang.UnsupportedOperationException: 
    Java Runtime Environment (JRE) version 1.6 is not supported by this driver.
    Use the sqljdbc4.jar class library, which provides support for JDBC 4.0.

我正在尝试扩展Magento API - 我已经按照大多数教程中的步骤进行了操作,并完成了以下操作.当我尝试调用任何扩展的api方法时,我不断从洋红色获得无效的资源路径错误.

在app/etc/modules中创建一个名为Woe_Services.xml的模块XML描述符

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <Woe_Services>
            <active>true</active>
            <codePool>local</codePool>
        </Woe_Services>
    </modules>
</config>

我创建了一个相应的目录结构:

-app
--code
---local
----Woe
-----Services

------etc
-------|api.xml
-------|config.xml

------Model
------- Catalog
-------- Product
--------- Attribute
---------- Api.php

我的config.xml文件如下:

<?xml version="1.0" encoding="UTF-8"?>
<config>
    <modules>
        <Woe_Services>
            <version>1.0</version>
        </Woe_Services>
    </modules>
    <global>
        <models>
            <catalog>
                <rewrite>
                    <product_attribute_api>Woe_Services_Model_Catalog_Product_Attribute_Api</product_attribute_api>
                </rewrite>
            </catalog>
        </models>
    </global>
</config>

我的api.xml文件如下:

<?xml version="1.0"?>
<config>
    <api>
        <resources>
            <catalog_product_attribute translate="title"
                module="catalog">
                <title>Product attributes API</title>
                <model>catalog/product_attribute_api</model>
                <acl>catalog/product</acl>
                <methods>
                    <create translate="title" module="catalog">
                        <title>Create new product attribute</title>
                        <acl>catalog/product/attribute/create</acl>
                    </create>
                    <delete translate="title" …
