Axis2 1.4.1客户端内存溢出实验.doc

Axis 1.4.1客户端内存溢出实验实验一：1. 下载Axis2 1.4.1/dist/ws/axis2/1_4_1/axis2-1.4.1-bin.zip 2. 新建axis2工程，并导入jar、modules、axis2.xml，目录结构如下：3. 编写服务类MyService.javapackage service;public class MyService public String getGreeting(String name) return 您好 + name; public void update(String data) System.out.println(已经更新); 4. 新建文件servicesTestServiceMETA-INFservices.xml Web Service service.MyService 5. 发布应用，访问:8080/axis2/services/myService?wsdl6. 通过运行下面bat，生成客户端代码echo offrem 这个地方定义了JAVA路径if not %JAVA_HOME% = goto okAxis2set JAVA_HOME=D:jdk1.6.0:okAxis2rem 这个地方定义了AXIS2的路径if not %AXIS2_HOME% = goto okWsdlset AXIS2_HOME=E:axis2-1.4.1:okWsdlrem 这个地方定义了WSDL文件的名称set wsdlinfo=:8080/axis2/services/myService?wsdlif exist %AXIS2_HOME%binstart.bat goto okHome:okHomerem set the classessetlocal EnableDelayedExpansionrem loop through the libs and add them to the class pathset AXIS2_CLASS_PATH=%AXIS2_HOME%FOR %c in (%AXIS2_HOME%lib*.jar) DO set AXIS2_CLASS_PATH=!AXIS2_CLASS_PATH!;%crem - Execute The Requested Command -echo Using AXIS2_HOME: %AXIS2_HOME%echo Using JAVA_HOME: %JAVA_HOME%set _RUNJAVA=%JAVA_HOME%binjava%_RUNJAVA% %JAVA_OPTS% -cp !AXIS2_CLASS_PATH! org.apache.axis2.wsdl.WSDL2Java -uri !wsdlinfo!7. 将生成的客户端java放到axis2工程下面，并修改包路径，如下图所示。8. 编写客户端调用类MyServiceClient.javapackage client;import client.MyServiceStub.GetGreeting;import client.MyServiceStub.GetGreetingResponse;public class MyServiceClient public static void main(String args)try while(true)MyServiceStub my = new MyServiceStub(:8080/axis2/services/myService);GetGreeting getGreeting = new GetGreeting();getGreeting.setName(chengq);GetGreetingResponse response = my.getGreeting(getGreeting);System.out.println(response.get_return();my.cleanup(); catch (Exception e) e.printStackTrace();9. 运行MyServiceClient.java10. 通过jdk自带jconsole监测内存使用情况，发现内存使用率逐渐升高，直到内存溢出。抛出错误异常信息如下：Exception in thread main java.lang.OutOfMemoryError: Java heap spaceat edu.emory.mathcs.backport.java.util.concurrent.ConcurrentHashMap$HashEntry.newArray(ConcurrentHashMap.java:207)at edu.emory.mathcs.backport.java.util.concurrent.ConcurrentHashMap$Segment.(ConcurrentHashMap.java:293)at edu.emory.mathcs.backport.java.util.concurrent.ConcurrentHashMap.(ConcurrentHashMap.java:614)at edu.emory.mathcs.backport.java.util.concurrent.ConcurrentHashMap.(ConcurrentHashMap.java:653)at org.apache.axis2.description.AxisDescription.(AxisDescription.java:78)at org.apache.axis2.description.AxisBindingMessage.(AxisBindingMessage.java:89)at org.apache.axis2.deployment.util.Utils.populateBindingOperation(Utils.java:1485)at org.apache.axis2.deployment.util.Utils.populateHttpEndpoint(Utils.java:1465)at org.apache.axis2.deployment.util.Utils.addEndpointsToService(Utils.java:1210)at org.apache.axis2.engine.AxisCcessEndpoints(AxisConfiguration.java:1249)at org.apache.axis2.engine.AxisConfiguration.addServiceGroup(AxisConfiguration.java:329)at org.apache.axis2.engine.AxisConfiguration.addService(AxisConfiguration.java:293)at org.apache.axis2.client.ServiceClient.configureServiceClient(ServiceClient.java:175)at org.apache.axis2.client.ServiceClient.(ServiceClient.java:143)at client.MyServiceStub.(MyServiceStub.java:103)at client.MyServiceStub.(MyServiceStub.java:89)at client.MyServiceStub.(MyServiceStub.java:140)at client.MyServiceClient2.main(MyServiceClient2.java:12)Exception in thread RMI TCP Connection(idle) java.lang.OutOfMemoryError: Java heap spaceException in thread RMI TCP Connection(idle) java.lang.OutOfMemoryError: Java heap spaceException in thread RMI TCP Connection(idle) java.lang.OutOfMemoryError: Java heap spaceException in thread RMI TCP Connection(idle) java.lang.OutOfMemoryError: Java heap spaceException in thread RMI TCP Connection(idle) java.lang.OutOfMemoryError: Java heap space* java.lang.instrument ASSERTION FAILED *: !errorOutstanding with message cant create byte arrau at ./././src/share/instrument/JPLISAgent.
