我有一个用于Eclipse的Java应用程序,使用Java Plug-in for Eclipse创建。我想通过Blackberry mds在Web服务器上调用web服务。我使用的代码有效,但不稳定。这意味着我连续100次成功与Web服务器联系,但过了一段时间,连接断开了。来自Blackberry的日志文件很多,不易阅读,但至少我觉得短语“无效套接字”对我不好。
我在我的代码中使用StreamConnection类,但我从一些示例代码中看到使用了httpConnection。任何人都知道何时使用HttpConnection而不是StreamConnection?
我在这里粘贴代码。也许你们中的一些人看到了我应该做的任何事情:
private boolean sendStatusMessage(String phoneNumber, String status) {
StreamConnection conn = null;
OutputStream output = null; //mari added
try {
String body = "<soapenv:Envelope xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:i3w=\"http://I3WebAction\">"
+ "<soapenv:Header/>"
+ "<soapenv:Body>"
+ "<i3w:I3SetMobileStatus><i3w:p_Status>"
+ status
+ "</i3w:p_Status><i3w:p_PhoneNumber>"
+ phoneNumber
+ "</i3w:p_PhoneNumber>"
+ "</i3w:I3SetMobileStatus></soapenv:Body></soapenv:Envelope>";
String URL = "socket://" + soapServer + ":" + port
+ ";deviceside=false";
conn = (StreamConnection) Connector.open(URL);
//OutputStream output = conn.openOutputStream();
output = conn.openOutputStream();
OutputStreamWriter writer = new OutputStreamWriter(output);
writer.write("POST /SOAPListener/I3SOAPISAPIU.dll HTTP/1.1\r\n");
writer.write("Accept-Encoding: gzip,deflate\r\n");
writer.write("Content-Type: text/xml;charset=UTF-8\r\n");
writer.write("SOAPAction: \"http://I3WebAction/I3SetMobileStatus\"\r\n");
writer.write("User-Agent: Jakarta Commons-HttpClient/3.1\r\n");
writer.write("Host: lvkdb01\r\n");
writer.write("Content-Length: " + body.length() + "\r\n");
writer.write("\r\n");
writer.write(body);
writer.flush();
writer.close(); //mari added
} catch (Exception e) {
Dialog.alert(e.getMessage());
return false;
} finally {
try {
// Close stream regardless of exceptions and return-points
output.close();
} catch (IOException e) {
// If closing the stream causes exception, the stream is most
// likely not open or available. We display an error message,
// and continues the program.
Dialog.alert(e.getMessage());
return false;
}
try {
// Close stream regardless of exceptions and return-points
conn.close();
} catch (IOException e) {
// If closing the stream causes exception, the stream is most
// likely not open or available. We display an error message,
// and continues the program.
Dialog.alert(e.getMessage());
return false;
}
}
return true;
}
我很感激有关此代码运行稳定的任何意见或想法。

默认情况下,所有通过BES的请求都会被转码。尝试关闭转码,看看是否能解决您的问题。要关闭转码,您需要传递以下标题。
关闭MD转码:(“x-rim-transcode-content”,“none”作为标题
MDS日志很有用(默认位置c:\ Program Files \ Research In Motion \ BlackBerryEnterprise Server \ Logs)/ 他们以“MDAT”结尾。可以按照这些说明更改日志记录级别。 http://docs.blackberry.com/en/admin/deliverables/14334/Change_logging_level_for_MDSCS_552126_11.jsp
您也可以在此处找到用于测试的详细HTTP日志记录,这可以帮助跟踪http消息。 http://docs.blackberry.com/en/admin/deliverables/14334/Change_activities_MDSCS_writes_to_log_827932_11.jsp
