【问题描述】：

我正在尝试编写一些简单的基于 GeoTools 的代码来访问 WFS 服务器。到目前为止，代码看起来像这样：

        String getCapabilities = "http://www.nws.noaa.gov/mdl/survey/pgb_survey/dev/OGC_services/ndfdOWSserver.php?SERVICE=WFS&Request=GetCapabilities";
        Map<String, String> connectionParameters = new HashMap<String, String>();
        connectionParameters.put("WFSDataStoreFactory:GET_CAPABILITIES_URL", getCapabilities);
        WFSDataStoreFactory  dsf = new WFSDataStoreFactory();
        try {
            WFSDataStore dataStore = dsf.createDataStore(connectionParameters);
            String types[] = dataStore.getTypeNames();
            for (int i = 0; i < types.length; i++) {
                System.out.println(types[i]);
            }
            SimpleFeatureSource source = dataStore.getFeatureSource("ndfd:Forecast_Gml2Point");
            SimpleFeatureCollection fc = source.getFeatures();
            while(fc.features().hasNext()){
                SimpleFeature sf = fc.features().next();
                System.out.println(sf.getAttribute("myname"));
            }
        } catch (IOException ex) {
            ex.printStackTrace();
        }
      }

这一直有效到调用 getFeatures() 的那一行，此时我得到可怕的 java.lang.NoClassDefFoundError: org.hsqldb.lib.FrameworkLogger 错误：

Exception in thread "main" java.lang.NoClassDefFoundError: Could not initialize class org.hsqldb.lib.FrameworkLogger

阅读类似的问题（例如this）表明类路径中缺少 hsqldb ——但事实并非如此。我已按照this page 上的说明下载 GeoTools 存档并将所有 Jars 添加到我的 Eclipse 项目中。（我不能使用 Maven，因为 Eclipse Maven 插件不能很好地与我们的代理配合使用。）我已经删除了所有建议的冲突罐子，以及 this thread 中建议的罐子。我检查了我的代码上的类路径，它包括“GeoTools 下载”项目和所有导出的 Jars。（我还明确地将所有 jar 添加到我的类路径中并得到相同的错误。）

如果我将项目转储到 Ant 构建文件，路径定义如下所示：

你会看到那里只有一个 epsg jar 文件，只有一个 jdbc jar。我对 12.2 版做了同样的事情，结果相同。

关于如何解决这个问题的任何想法？任何帮助表示赞赏！

【问题讨论】：

真的帮不上忙，因为我们真的不支持在没有 maven 的情况下进行构建，但是您缺少 hsqldb 依赖项而不是 geotools 依赖项。
什么依赖？我的路径中有 hsqldb-2.2.8.jar。（我无法用 maven 构建，因为这台机器离线。）
可能有hsqldb依赖的jar，尝试在连接的机器上构建到ser
Hsqldb 似乎不依赖任何 jars。

【解决方案1】：

我无法使用 maven 重现您的问题。我认为解决此问题的唯一可靠方法是在在线机器上使用 mvn 构建您的项目，然后复制所需的依赖项。或者，如果您真的必须按照您的方式继续，请尝试一次取出一个罐子，看看是哪一个导致了问题。

编辑

我可以按照快速入门中的过时步骤重现错误，我能找到的最佳猜测是this，这表明存在日志记录问题。这似乎是合理的，因为它试图在问题出现时抛出 SAX 错误。

如果您删除所有其他罐子（不在我下面的列表中），它将起作用。

但是 GeoTools 日志记录代码是一个复杂的地方，我害怕踩到，所以尝试添加 log4j 或切换到使用 epsg-wkt，因为这也可以解决问题。

如果这有帮助，这就是 Maven 认为你应该需要的依赖项：

【讨论】：

首先，非常感谢您为帮助所付出的努力。对此，我真的非常感激。检查该依赖项列表，除了 xml-apis.jar 之外，它们都在我的构建路径中。我发现并添加了它，但这并没有解决错误。（顺便说一句，除了 xml-apis.jar 之外，所有这些 jar 都包含在 GeoTools 中。是否需要将其添加到发行版中？）
至于不使用 Maven，我按照“下载 GeoTools”下Quickstart page for Eclipse 的说明进行操作。如果您有时间，您可以尝试一下，看看您是否遇到与我看到的相同的错误？
