NoSuchMethodError on creating a web service client

Question

I'm new to java and web services and axis2 . I recently created a web service using some tutorials. When I first follow the tutorial eclipse let me create a client. But when I try to create a new project and a new web service client it gives NoSuchMethodError . Which exactly looks like this:

Exception occurred while code generation for WSDL : java.lang.NoSuchMethodError: javax.wsdl.Operation.getExtensionAttributes()Ljava/util/Map; java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.jst.ws.axis2.consumption.core.utils.WSDL2JavaGenerator.getAxisService(WSDL2JavaGenerator.java:379) at org.eclipse.jst.ws.axis2.consumption.core.command.Axis2ClientCodegenCommand.execute(Axis2ClientCodegenCommand.java:94) at org.eclipse.wst.command.internal.env.core.fragment.CommandFragmentEngine.runCommand(CommandFragmentEngine.java:419) at org.eclipse.wst.command.internal.env.core.fragment.CommandFragmentEngine.visitTop(CommandFragmentEngine.java:359) at org.eclipse.wst.command.internal.env.core.fragment.CommandFragmentEngine.moveForwardToNextStop(CommandFragmentEngine.java:254) at org.eclipse.wst.command.internal.env.ui.widgets.SimpleCommandEngineManager$6.run(SimpleCommandEngineManager .java:294) at org.eclipse.jface.operation.ModalContext.runInCurrentThread(ModalContext.java:369) at org.eclipse.jface.operation.ModalContext.run(ModalContext.java:313) at org.eclipse.jface.wizard.WizardDialog.run(WizardDialog.java:934) at org.eclipse.wst.command.internal.env.ui.widgets.SimpleCommandEngineManager.runForwardToNextStop(SimpleCommandEngineManager.java:264) at org.eclipse.wst.command.internal.env.ui.widgets.WizardPageManager.runForwardToNextStop(WizardPageManager.java:91) at org.eclipse.wst.command.internal.env.ui.widgets.WizardPageManager.performFinish(WizardPageManager.java:262) at org.eclipse.wst.command.internal.env.ui.widgets.DynamicWizard.performFinish(DynamicWizard.java:380) at org.eclipse.jface.wizard.WizardDialog.finishPressed(WizardDialog.java:742) at org.eclipse.jface.wizard.WizardDialog.buttonPressed(WizardDialog.java:373) at org.eclipse.jface.dialogs.Dialog$2.widgetSelected(Dialog.java:618) at org.eclipse.swt.widgets.TypedListener.handleEvent(TypedListener.java :227) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:66) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:938) at org.eclipse.swt.widgets.Display.runDeferredEvents(Display.java:3682) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3293) at org.eclipse.jface.window.Window.runEventLoop(Window.java:820) at org.eclipse.jface.window.Window.open(Window.java:796) at org.eclipse.ui.actions.NewWizardAction.run(NewWizardAction.java:182) at org.eclipse.jface.action.Action.runWithEvent(Action.java:498) at org.eclipse.jface.action.ActionContributionItem.handleWidgetSelection(ActionContributionItem.java:546) at org.eclipse.jface.action.ActionContributionItem.access$2(ActionContributionItem.java:490) at org.eclipse.jface.action.ActionContributionItem$5.handleEvent(ActionContributionItem.java:402) at org.eclipse.swt.widgets.EventTable.sendEvent(EventTable.java:66) at org.eclipse.swt.widgets.Widget.sendEvent(Widget.java:938) at org.eclipse.swt.widgets.Display.run DeferredEvents(Display.java:3682) at org.eclipse.swt.widgets.Display.readAndDispatch(Display.java:3293) at org.eclipse.ui.internal.Workbench.runEventLoop(Workbench.java:2389) at org.eclipse.ui.internal.Workbench.runUI(Workbench.java:2353) at org.eclipse.ui.internal.Workbench.access$4(Workbench.java:2219) at org.eclipse.ui.internal.Workbench$4.run(Workbench.java:466) at org.eclipse.core.databinding.observable.Realm.runWithDefault(Realm.java:289) at org.eclipse.ui.internal.Workbench.createAndRunWorkbench(Workbench.java:461) at org.eclipse.ui.PlatformUI.createAndRunWorkbench(PlatformUI.java:149) at org.eclipse.ui.internal.ide.application.IDEApplication.start(IDEApplication.java:106) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:169) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:106) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:76) at org.eclipse.core.r untime.adaptor.EclipseStarter.run(EclipseStarter.java:363) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:176) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:508) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:447) at org.eclipse.equinox.launcher.Main.run(Main.java:1173) Caused by: java.lang.NoSuchMethodError: javax.wsdl.Operation.getExtensionAttributes()Ljava/util/Map;

im using axis2-1.6.1 and it says java compliance level is 6 I googled it but couldn't find a relevant solution to this problem. Any help is appreciated.

Answer 1

I had the same problem and solved it by checking out my WEB-INF/lib .
I had two of any AXIS2 jar files in my WEB-INF .
It also happens if jar files from two different versions of axis2 were copied to WEB-INF .

Hope it works :-)

Answer 2

The problem is that Eclipse "isn't finding something".

Here's one example; the solution here was to:

1. Make sure all necessary .jar libraries were included in the project

2. Select "search local classes first" in Class loading when doing a deploy

Answer 3

Please follow the following instructions.

1. Make Sure Your Web Service is Available in the Server. Please check it by viewing the WSDL of you web service.
2. After that follow the instructions on one of these articles,

BottomUpAxis2WebService

It works for me fine. Make sure that your code-gen plug-in is properly installed for eclipse.
