[英]HtmlUnit first steps
I am trying to set up my first example program with HtmlUnit.我正在尝试使用 HtmlUnit 设置我的第一个示例程序。 This is the code:
这是代码:
import com.gargoylesoftware.htmlunit.html.HtmlPage;
import com.gargoylesoftware.htmlunit.WebClient;
public class test {
public static void main(String[] args) throws Exception {
WebClient client = new WebClient();
HtmlPage currentPage = client.getPage("http://www.oddsportal.com/matches/soccer");
client.waitForBackgroundJavaScript(10000);
String textSource = currentPage.asXml();
System.out.println(textSource);
}
}
then i compile:然后我编译:
javac -cp lib/htmlunit-2.9.jar test.java
javac -cp lib/htmlunit-2.9.jar 测试.java
but when i try to exec test i get但是当我尝试执行测试时,我得到
java -cp lib/htmlunit-2.9.jar test
java-cp lib/htmlunit-2.9.jar 测试
Exception in thread "main" java.lang.NoClassDefFoundError: test Caused by: java.lang.ClassNotFoundException: test at java.net.URLClassLoader$1.run(URLClassLoader.java:217) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:205) at java.lang.ClassLoader.loadClass(ClassLoader.java:321) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) at java.lang.ClassLoader.loadClass(ClassLoader.java:266) Could not find the main class: test.
线程“main”中的异常 java.lang.NoClassDefFoundError: test Caused by: java.lang.ClassNotFoundException: test at java.net.URLClassLoader$1.run(URLClassLoader.java:217) 在 java.security.doPcessingMethod(security.doPcessingMethod) ) at java.net.URLClassLoader.findClass(URLClassLoader.java:205) at java.lang.ClassLoader.loadClass(ClassLoader.java:321) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:294) at java .lang.ClassLoader.loadClass(ClassLoader.java:266) 找不到主 class: 测试。 Program will exit.
程序将会退出。
where is the problem?问题出在哪里? i lack some other packages?
我缺少其他一些包裹?
you may have to add the current path to the classpath.您可能必须将当前路径添加到类路径中。
On Unix/Linux/Mac:在 Unix/Linux/Mac 上:
java -cp .:lib/htmlunit-2.9.jar test
On Windows:在 Windows 上:
java -cp .;lib/htmlunit-2.9.jar test
EDIT There is actually more jars needed for htmlunit that just htmlunit-2.9.jar.编辑htmlunit 实际上需要更多的 jars 而不仅仅是 htmlunit-2.9.jar。 Therefore, considering that all those required jars are located in the lib/ directory, you should actually invoke the following:
因此,考虑到所有需要的 jars 都位于 lib/ 目录中,您实际上应该调用以下命令:
On Unix/Linux/Mac:在 Unix/Linux/Mac 上:
java -cp .:lib/* test
If you run this command from a shell, you also need to escape the wildcard (with a '\') or put the whole classpath within quotes to avoid shell expansion.如果您从 shell 运行此命令,您还需要转义通配符(使用“\”)或将整个类路径放在引号内以避免 shell 扩展。
On Windows:在 Windows 上:
java -cp .;lib/* test
This works:这有效:
java -cp.:lib/* test
java -cp.:lib/* 测试
