tomcat stops randomly. why??
Hi All, I have installed Apache Tomcat 4.0.4 web server to my computer. Tomcat is running as a service on this NT machine. But sometimes it does not respond. I have no explanation for it. I looked at the log files to find out sth. The only thing that I found is in the localhost_examples_log.2002-08-13.txt file. There is a recurring error. But the time that the error occur at is not the time that the server is unreacheable. (In the services window it is seemed as working properly.) What may the reason for this problem? --The following error --NT machine --High Load(In fact load is not so high) --Or what ??? Thanks in advance, Serdar By the way the error is that is in localhost_examples_log.2002-08-13.txt : !--StartFragment--2002-08-13 20:58:36 StandardWrapperValve[default]: Servlet.service() for servlet default threw exception java.net.SocketException: Connection aborted by peer: socket write error at java.net.SocketOutputStream.socketWrite(Native Method) at java.net.SocketOutputStream.write(SocketOutputStream.java:83) at org.apache.catalina.connector.ResponseBase.flushBuffer(ResponseBase.java:674) at org.apache.catalina.connector.HttpResponseBase.flushBuffer(HttpResponseBase.java:764) at org.apache.catalina.connector.ResponseBase.write(ResponseBase.java:647) at org.apache.catalina.connector.ResponseStream.write(ResponseStream.java:312) at org.apache.catalina.connector.http.HttpResponseStream.write(HttpResponseStream.java:189) at org.apache.catalina.servlets.DefaultServlet.copyRange(DefaultServlet.java:1903) at org.apache.catalina.servlets.DefaultServlet.copy(DefaultServlet.java:1652) at org.apache.catalina.servlets.DefaultServlet.serveResource(DefaultServlet.java:1197) at org.apache.catalina.servlets.DefaultServlet.doGet(DefaultServlet.java:519) at javax.servlet.http.HttpServlet.service(HttpServlet.java:740) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:247) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:193) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:243) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:190) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) at org.apache.catalina.valves.CertificatesValve.invoke(CertificatesValve.java:246) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardContext.invoke(StandardContext.java:2347) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:180) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) at org.apache.catalina.valves.ErrorDispatcherValve.invoke(ErrorDispatcherValve.java:170) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:170) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:468) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:174) at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566) at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472) at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943) at org.apache.catalina.connector.http.HttpProcessor.process(HttpProcessor.java:1027) at org.apache.catalina.connector.http.HttpProcessor.run(HttpProcessor.java:1125) at java.lang.Thread.run(Thread.java:484)

I cannot access my site over https
Hi, I installed SSL on my apache tomcat 4.0.4 web server and I was able to access the site over https. But now I cannot access. Some changes are done to the machine and web server. For instance iPlanet is installed and as a second change there are two hosts on tomcat... I can access the secure page on the local machine (not https://localhost, but https://www.sth.com) but the same url (https://www.sth.com) does not displayed when called from another machine. What may be the reasons , thanks in advance, serdar
sevlets and applets
hi, i have a question about servlets. in my applet I use showdocument method to open a servlet in a new browser window. this servlet reads the contents of a file that user choose. this servlet needs the send the content of the file to the applet but since showdocument is used out.println() command in the servlet shows the content in the browser window. I may use urlconnection.connect() in applet to call the servlet but this time the wizard for file choosing will not be displayed. (servlet displays a form in doGet method and get the contents of the form in doPost method and at the end of the doPost method result must be given to the applet.) my question is with showdocument method of applet can i get the result of a servlet. (i know quite an awkward question but i was not able to write more simpler) thanks in advance, serdar
