WebDynpro : java.lang.NoSuchMethodError

[Former Member]

I have deployed a WebDynpro Application to a the J2EE server (SP17 ). However the Webdynpro fails to run and returns with a "java.lang.NoSuchMethodError" error.

Reading through the forums i see that this problem points to the J2EE Server and NWDS development WebDynPro Runtime versions being different. But the NWDS version is 2.017(200605050350) and the Server WebDynPro build being : 6.4017.00.0000.20060503180106.

If i check the Plugin Information in NWDS for Web Dynpro Runtime the version shows 2.0.0, is the correct, am i looking at another Reinstall ?

Is there something else i need to check ?

Thanks,

Daniel

The error that i see when i run the WebDynpro is

"java.lang.NoSuchMethodError: com.sap.tc.webdynpro.progmodel.context.Context.createNode(Ljava/lang/String;Ljava/lang/Class;ZZZZZZLjava/lang/String;[Lcom/sap/tc/webdynpro/progmodel/context/AttributeInfo;[Lcom/sap/tc/webdynpro/progmodel/context/NodeInfo;)Lcom/sap/tc/webdynpro/progmodel/context/NodeInfo; "

Hi daniel,

I also faced the same problem today.

I faced this while creating a dynamic node in my interface controller.

Method i wrote was:

IWDNodeInfo nodeInfo =
			wdContext.getNodeInfo().addChild(
				"DynamicPurchaseOrder",
				null,
				true,
				true,
				false,
				false,
				false,
				true,
				null,
				null,
				null);

Which simply creates a node at runtime.

And Error which i got is

java.lang.NoSuchMethodError: com.sap.tc.webdynpro.progmodel.context.Context.createNode(Ljava/lang/String;Ljava/lang/Class;ZZZZZZLjava/lang/String;[Lcom/sap/tc/webdynpro/progmodel/context/AttributeInfo;[Lcom/sap/tc/webdynpro/progmodel/context/NodeInfo;)Lcom/sap/tc/webdynpro/progmodel/context/NodeInfo;

can you please share how did you manage to solve this error?

Hi Ashish,

Deploy the used DC. This build both the DCs and deploy your application.

This will solve the problem.

Hi Apurva,

In my case i am using local WD project

The reason seems to be something with the way i am creating a dynamic node

The code that i used does not contain the method "createnode".

I am using

IWDNodeInfo nodeInfo =

wdContext.getNodeInfo().addChild(

"DynamicCustomer", null,true,true,false,false,false,true,null,null, null);

whereas error text shows method as "createNode".

java.lang.NoSuchMethodError: com.sap.tc.webdynpro.progmodel.context.Context.createNode(Ljava/lang/String;Ljava/lang/Class;ZZZZZZLjava/lang/String;[Lcom/sap/tc/webdynpro/progmodel/context/AttributeInfo;[Lcom/sap/tc/webdynpro/progmodel/context/NodeInfo;)Lcom/sap/tc/webdynpro/progmodel/context/NodeInfo;

Not sure though whats the exact reason.

You should get more information with the error. Which method isn't found? Are you using an external library?
