嵌入在HTML中的JAVA Applet在操作過程中掛起

Question

我有一臺Web服務在一臺機器上運行，我想通過Applet訪問該Web服務。獨立的Applet完美無瑕地運行。但是，當我將該applet嵌入到html文件中時，真正的問題就開始了。由於某些客戶端限制，我需要將小程序嵌入到Html文件中。當我打開html頁面但不訪問Web服務時，applet開始。

我知道Applet必須簽名才能訪問所有可用的資源。我已經簽署了罐子，但它仍然掛起。爲了解決這個問題，我想到了監視從Web服務運行的客戶端到服務器的網絡流量。我發現有一些區別..當我運行獨立的JAVA Applet（JAR文件）時：它調用精確的Web服務鏈接並獲取響應。另一個最重要的要注意的是，它調用javaw.exe和完美的POST請求（下面顯示的第三個請求）。

javaw.exe 172.22.1.98 SANKET-BA4C8C90  TCP TCP:Flags=...A..S., SrcPort=HTTP Alternate(8080), DstPort=3868, PayloadLen=0, Seq=271218130, Ack=957649749, Win=65535 (Scale factor not supported) = 65535 {TCP:1, IPv4:15}

當我運行嵌入在HTML文件中的同一個applet：我得到不同的結果，其中，它調用的java.exe，並呼籲不當鏈接到網絡服務獲取（指着serviceexception.class而不是POST/LEDLabServer /服務/閃爍）

PS：我正在使用JAXRPC進行Web服務。

有人可以幫助我嗎？

的問題是從你的日誌很明顯：

HTTP：響應，HTTP/1.1，狀態：未發現，網址：/LEDLabServer/sampleBlinkProxy/javax/xml/rpc/ServiceException.class

您沒有將類文件安裝在正確的位置，所以瀏覽器找不到它們。
