ActiveXImpl 调用jsConstructor 异常
Exception invoking jsConstructor caused by ActiveXImpl
我在尝试通过 htmlunit webclient 访问页面时遇到此错误：
代码示例：
final WebClient webClient = new WebClient(BrowserVersion.INTERNET_EXPLORER_11);
WebClientOptions webClientOptions = webClient.getOptions();
webClientOptions.setSSLClientCertificate(new URL("File:C:\Cert.pfx"), "dubqf!$@", "PKCS12");
webClientOptions.setUseInsecureSSL(true);
webClientOptions.setSSLTrustStore(new URL("File:C:\Program Files (x86)\Java\jdk1.7.0_01\jre\lib\security\cacerts"), "changeit", "jks");
webClientOptions.setThrowExceptionOnScriptError(false);
webClientOptions.setThrowExceptionOnFailingStatusCode(false);
webClientOptions.setActiveXNative(true);
final HtmlPage pg = webClient.getPage(u);
HtmlPasswordInput pass = (HtmlPasswordInput) pg.getElementById("PasswordTxt");
HtmlTextInput ac = (HtmlTextInput) pg.getElementById("AgentCode");
HtmlTextInput oc = (HtmlTextInput) pg.getElementById("OfficeCode");
HtmlTextInput ut = (HtmlTextInput) pg.getElementById("UserTxt");
ac.click(); ac.type("1058");
oc.click(); oc.type("07");
ut.click(); ut.type("gebrane");
pass.click(); pass.type("gebran.h2");
ScriptResult result = pg.executeJavaScript("__doPostBack('LogInLinkBut','')");
HtmlPage newPage = (HtmlPage) result.getNewPage();

已解决。看来我应该更改 jacob.jar 的 .dll 文件的位置。它被放在 web-inf/lib 下。我将其移至 tomcat/bin 位置并且运行良好。
