Dear all: I use Tomcat 5.5.9 and Mysql Server 5.0 (with the driver mysql-connector-java-3.1.12-bin.jar)
to run my Application on Windows XP. It run smoothly many times throughout the whole Application without any problem ! But in an unexpected time, I get the following Error messages. I can only ' Stop ' Tomcat 5.5.9 and ' Start ' it again, Then it will be Ok to run my Application. Can you tell me how to solve the problem ? by NanFei javax.servlet.ServletException: Communications link failure due to underlying exception: ** BEGIN NESTED EXCEPTION ** java.net.SocketException MESSAGE: java.net.BindException: Address already in use: JVM_Bind STACKTRACE: java.net.SocketException: java.net.BindException: Address already in use: JVM_Bind at com.mysql.jdbc.StandardSocketFactory.connect(StandardSocketFactory.java:156) at com.mysql.jdbc.MysqlIO.<init>(MysqlIO.java:284) at com.mysql.jdbc.Connection.createNewIO(Connection.java:2555) at com.mysql.jdbc.Connection.<init>(Connection.java:1485) at com.mysql.jdbc.NonRegisteringDriver.connect(NonRegisteringDriver.java:266) at java.sql.DriverManager.getConnection(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at upload.mysqlConn.<init>(mysqlConn.java:39) at upload.mysqlConn.<init>(mysqlConn.java:19) at org.apache.jsp.queryChoice_jsp._jspService(org.apache.jsp.queryChoice_jsp:67) at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:97) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:322) at org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:291) at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:241) at javax.servlet.http.HttpServlet.service(HttpServlet.java:802) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:252) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:173) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValvejava:213) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValvejava:178) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:126) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:105) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:107) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:148) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:856) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.processConnection(Http11Protocol.java:744) at org.apache.tomcat.util.net.PoolTcpEndpoint.processSocket(PoolTcpEndpoint.java:527) at org.apache.tomcat.util.net.LeaderFollowerWorkerThread.runIt(LeaderFollowerWorkerThread.java:80) at org.apache.tomcat.util.threads.ThreadPool$ControlRunnable.run(ThreadPool.java:684) at java.lang.Thread.run(Unknown Source) ** END NESTED EXCEPTION **
