java - Exception when downloading huge files using struts framework -


sorry if question similar other present, posting none of solutions offered have worked me.

i have struts action of type 'stream' called download, leads downloading file website(running in https).

code:

   inputstream inp;     public string execute {            inp = //get inputstream;        return success;     }  struts  <action name="download" class="abc">        <result name="success" type="stream">       <param name="contenttype">application/octet-stream</param>       <param name="inputname">inp</param>       <param name="contentdisposition">attachment;filename="abc"</param>       <param name="buffersize">1024</param>        </result> </action>

for downloading large files across browsers, throws exception :

java.lang.illegalstateexception: getoutputstream() has been called response         @ org.apache.catalina.connector.response.getwriter(response.java:611)         @ org.apache.catalina.connector.responsefacade.getwriter(responsefacade.java:198)         @ javax.servlet.servletresponsewrapper.getwriter(servletresponsewrapper.java:122)         @ org.apache.jasper.runtime.jspwriterimpl.initout(jspwriterimpl.java:125)         @ org.apache.jasper.runtime.jspwriterimpl.flushbuffer(jspwriterimpl.java:118)         @ org.apache.jasper.runtime.pagecontextimpl.release(pagecontextimpl.java:180)         @ org.apache.jasper.runtime.jspfactoryimpl.internalreleasepagecontext(jspfactoryimpl.java:118)         @ org.apache.jasper.runtime.jspfactoryimpl.releasepagecontext(jspfactoryimpl.java:77)  @ org.apache.jsp.shared.baseerror_jsp._jspservice(baseerror_jsp.java:87)         @ org.apache.jasper.runtime.httpjspbase.service(httpjspbase.java:70)         @ javax.servlet.http.httpservlet.service(httpservlet.java:820)         @ org.apache.catalina.core.applicationfilterchain.internaldofilter(applicationfilterchain.java:290)         @ org.apache.catalina.core.applicationfilterchain.dofilter(applicationfilterchain.java:206)         @ org.apache.catalina.core.applicationdispatcher.invoke(applicationdispatcher.java:646)         @ org.apache.catalina.core.applicationdispatcher.doinclude(applicationdispatcher.java:551)         @ org.apache.catalina.core.applicationdispatcher.include(applicationdispatcher.java:488)         @ org.apache.tiles.servlet.context.servlettilesrequestcontext.include(servlettilesrequestcontext.java:217)         @ org.apache.tiles.servlet.context.servlettilesrequestcontext.dispatch(servlettilesrequestcontext.java:177)         @ org.apache.tiles.context.tilesrequestcontextwrapper.dispatch(tilesrequestcontextwrapper.java:72)         @ org.apache.struts2.tiles.strutstilesrequestcontext.dispatch(strutstilesrequestcontext.java:88)         @ org.apache.tiles.impl.basictilescontainer.render(basictilescontainer.java:606)         @ org.apache.tiles.impl.basictilescontainer.render(basictilescontainer.java:246)         @ org.apache.struts2.views.tiles.tilesresult.doexecute(tilesresult.java:105)         @ org.apache.struts2.dispatcher.strutsresultsupport.execute(strutsresultsupport.java:186)         @ com.opensymphony.xwork2.defaultactioninvocation.executeresult(defaultactioninvocation.java:373)         @ com.opensymphony.xwork2.defaultactioninvocation.invoke(defaultactioninvocation.java:277)         @ org.apache.struts2.impl.strutsactionproxy.execute(strutsactionproxy.java:52)         @ org.apache.struts2.dispatcher.dispatcher.serviceaction(dispatcher.java:498)         @ org.apache.struts2.dispatcher.filterdispatcher.dofilter(filterdispatcher.java:434)         @ org.apache.catalina.core.applicationfilterchain.internaldofilter(applicationfilterchain.java:235)         @ org.apache.catalina.core.applicationfilterchain.dofilter(applicationfilterchain.java:206)         @ java.security.accesscontroller.doprivileged(native method)         @ javax.security.auth.subject.doas(subject.java:415)         @ org.apache.catalina.core.applicationfilterchain.internaldofilter(applicationfilterchain.java:235)         @ org.apache.catalina.core.applicationfilterchain.dofilter(applicationfilterchain.java:206)         @ org.apache.catalina.core.applicationfilterchain.internaldofilter(applicationfilterchain.java:235)         @ org.apache.catalina.core.applicationfilterchain.dofilter(applicationfilterchain.java:206)         @ org.apache.catalina.core.standardwrappervalve.invoke(standardwrappervalve.java:233)         @ org.apache.catalina.core.standardcontextvalve.invoke(standardcontextvalve.java:191)         @ org.apache.catalina.authenticator.authenticatorbase.invoke(authenticatorbase.java:563)         @ org.apache.catalina.core.standardhostvalve.invoke(standardhostvalve.java:127)         @ org.apache.catalina.valves.errorreportvalve.invoke(errorreportvalve.java:103)         @ org.apache.catalina.valves.accesslogvalve.invoke(accesslogvalve.java:615)         @ org.apache.catalina.core.standardenginevalve.invoke(standardenginevalve.java:109)         @ org.apache.catalina.connector.coyoteadapter.service(coyoteadapter.java:293)         @ org.apache.coyote.http11.http11processor.process(http11processor.java:861)         @ org.apache.coyote.http11.http11protocol$http11connectionhandler.process(http11protocol.java:606)         @ org.apache.tomcat.util.net.jioendpoint$worker.run(jioendpoint.java:489)         @ java.lang.thread.run(thread.java:724)

after exception occurs, file download stops in between , user has incomplete file.
