Question

我目前正在使用NetBean IDE中的Web服务。我正在使用Apache HttpClient将GET请求发送到某些RESTful API。问题是，它在junit测试中确实能很好地工作，但是当我将其编译并存入Glassfish时，它显示以下错误：

Info:   wsimport successful

这是我发送GET请求的代码。有什么问题吗？

protected String getResponse(String url) throws IOException, ProviderNotAvailableException{
        HttpGet request = new HttpGet(url);

        CloseableHttpResponse response = httpClient.execute(request);

        HttpEntity entity = response.getEntity();

        if (entity != null) {
            String result = EntityUtils.toString(entity);
            return result;
        } else {
            throw new ProviderNotAvailableException("Http entity is null.");
        }
}

我的jdk版本是1.8，NetBean版本是11.0。再次，它在junit测试中效果很好。

我曾经使用过JDK v1.8。升级到1.8u221并解决了问题。

java.lang.NoClassDefFoundError：sun / security / ssl / HandshakeStateManager
