Causes and treatment of java.io.IOException:Stream closed anomalies

Java.io.IOException:Stream closed

multiple threads index the same input stream, when a thread has finished executing, the InputStream is closed; the thread that reads information from the stream is thrown java.io.IOException: Stream closed exception.

   finally find out the origin of this anomaly, originally two pages call a JSP, the built-in object in this JSP
The exception that occurs when an out executes out.close (), that is, when a thread (corresponding to a JSP) finishes executing the
, the stream is closed, and another JSP that is reading the information from this stream is thrown 
java.io.IOException: Stream closed exception.

Modify the previous code:

Public object senddata (STRING JSONSTR)  {// 1.  Specifies the WebService namespace and method name of the call Soapobject  rpc = new soapobject (Namespace, methodname);// 2.  sets the parameter value of the calling method, which is optional, If the method has no parameters, you can omit this step rpc.addproperty ("arg000",  jsonstr);// 3.  generate the SOAP request information that calls the WebService method. Soapserializationenvelope envelope = new soapserializationenvelope (SOAPENVELOPE.VER11); envelope.encodingstyle =  "UTF-8";envelope.bodyout = rpc;//  Envelope.setoutputsoapobject (RPC);// 4.//  creates Httptransportse objects. The constructor of the Httptransportse class allows you to specify the Urlhttptransportse ht = new httptransportse of the WebService WSDL document ( URL);ht.debug = true;object detail1 = null;try {// 5.  Use the call method to invoke the WebService method Ht.call (Null, envelope);// detail =  (soapobject)   Envelope.getresponse ();// 6.  uses the GetResponse method to obtain the return result of the WebService method detail1 =  Envelope.getresponse ();}  catch  (ioexception e)  {// todo auto-generated catch blocke.printstacktrace ();}  catch  (xmlpullparserexception e)  {// TODO Auto-generated catch  Blocke.printstacktrace ();} Return detail1;}
