I have implemented TServlet for the java sample given the Thrift website). But I am getting the below exception when I call from client: java.lang.InstantiationException: com.cts.course.thrift.CourseServlet at java.lang.Class.newInstance0(Unknown Source) at java.lang.Class.newInstance(Unknown Source) at org.apache.catalina.core.StandardWrapper.loadServlet(StandardWrapper.jav a:1104) at org.apache.catalina.core.StandardWrapper.allocate(StandardWrapper.java:8 06) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValv e.java:129) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValv e.java:175) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java :128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java :102) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve. java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:2 86) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:84 4) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process( Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) at java.lang.Thread.run(Unknown Source) Source Code: package com.cts.course.thrift; import java.util.List; import org.apache.thrift.TException; import org.apache.thrift.TProcessor; import org.apache.thrift.protocol.TBinaryProtocol; import org.apache.thrift.protocol.TProtocolFactory; import org.apache.thrift.server.TServlet; import com.cts.course.thrift.gen.Course; import com.cts.course.thrift.gen.CourseNotFound; import com.cts.course.thrift.gen.CourseService; import com.cts.course.thrift.gen.UnacceptableCourse; import com.ociweb.jnb.db.Database; public class CourseServlet extends TServlet { /** * */ private static final long serialVersionUID = -6700299292172345870L; public CourseServlet(TProcessor processor, TProtocolFactory inProtocolFactory, TProtocolFactory outProtocolFactory) { super(new CourseService.Processor(new CourseHandler()), new TBinaryProtocol.Factory(), new TBinaryProtocol.Factory()); } public CourseServlet(TProcessor processor, TProtocolFactory protocolFactory) { super(new CourseService.Processor(new CourseHandler()), new TBinaryProtocol.Factory()); } public static class CourseHandler implements CourseService.Iface { public Database db = new Database(); @Override public List<String> getCourseInventory() throws TException { return db.getCourseList(); } @Override public Course getCourse(String courseNumber) throws CourseNotFound, TException { final com.ociweb.jnb.db.Course dbCourse = db .getCourse(courseNumber); if (dbCourse != null) { return ConversionHelper.fromDbCourse(dbCourse); } return null; } @Override public void addCourse(Course course) throws UnacceptableCourse, TException { com.ociweb.jnb.db.Course dbCourse = ConversionHelper .toDbCourse(course); db.addCourse(dbCourse); } @Override public void deleteCourse(String courseNumber) throws CourseNotFound, TException { if (db.getCourse(courseNumber) != null) { db.deleteCourse(courseNumber); } } } } Thanks and Regards Prabakaran.N Architect - Technology, GTO - SOA CoE Cognizant Technology Solutions, BTP, Bangalore Mobile:+91-9739386923; Vnet: 58157; Direct: +91-80-30748157 This e-mail and any files transmitted with it are for the sole use of the intended recipient(s) and may contain confidential and privileged information.
