NoSuchMethodError: ... (LJava/lang/String)
Dear all,
I am a new Axis2 user. Today I got a weird exception when calling a Web
service.
This Web service is deployed on Tomcat/Axis2. I need to transmit an object
(parameter) to it. The object contains a String attribute. The object is
received correctly. However, when calling a local method on the remote
machine, it got the following errors. I noticed that the method
SelectCategoriedHubByKey(Ljava/lang/String key) cannot be found on the
machine. Actually, the method should be SelectCategoriedHubByKey(String
key). Why is the parameter changed from String to LJava/lang/String? How to
solve the problem?
Thanks so much!
LB

Jose,
I changed the parameter from String to String[]. However it got the same
exception. The only different thing is that Ljava/lang/String to
[Ljava/lang/String. I really don't understand what's going on! Could you
tell me how to solve it?
Thanks,
LB

Jose
I appreciate so much for your help!
You mean I should change the parameter of the local method from String to
String[]? I will take a try.
Thanks,

Dear Andreas,
After checking my system carefully, I noticed that one package was compiled
by JDK 1.3. After compiling by JDK 1.6, everything is fine.
I appreciate so much for your and other guys' help!
Best,
LB

Re: NoSuchMethodError: ... (LJava/lang/String)
Posted by Andreas Veithen <an...@gmail.com>.
That is your interpretation. What the stack trace really says is that
Axis2 successfully invokes your service (namely
CategorizedHubService#getCategorizedHub), but that there is an issue
in your service. A NoSuchMethodError (in contrast to
NoSuchMethodException) usually indicates a problem with the build
(wrong version of a class packaged into the application) or a class
loader problem (multiple versions of the same class in classpaths of
different class loaders).

Re: NoSuchMethodError: ... (LJava/lang/String)
Posted by Bing Li <lb...@gmail.com>.
In Axis2, no WSDD is required.
POJO is what I am using. At the server, users just need to write OO program
as usual. No particular work is required. I notice that the sample,
addressbook, in the directory of POJO accompanied with AXIS binary package,
works fine. My case should be the same as that. But the method on the server
is not recognized for my method's parameters is changed from String to
Ljava/lang/java!
What I am wondering why Ljava/lang/java comes out? I never use it. I believe
a proper design of Web services development system should NOT bother users
with so many underlying techniques.
Thanks,
LB

Well, I'm not expert at all. The exception is in the server side, right? Can you share the wsdd?

Dear Jose,
I didn't use WSDL to generate any stud code. What I am currently using is
POJO. I don't understand why AXIS has such a design on Web services?

Re: NoSuchMethodError: ... (LJava/lang/String)
Posted by Bing Li <lb...@gmail.com>.
Sorry to send the question again. I forgot putting the example code in the
previous email. The code is as follows. It works fine. However, my code does
not.
public class AddressBookService {
private HashMap entries = new HashMap();
private MyAddress myaddr = new MyAddress();
/**
* Add an Entry to the Address Book
* @param entry
*/
public void addEntry(Entry entry) {
this.entries.put(entry.getName(), entry);
}
/**
* Search an address of a person
*
* @param name the name of the person whose address needs to be found
* @return return the address entry of the person.
*/
public Entry findEntry(String name) {
return myaddr.getAddr(name);
}
}

Re: NoSuchMethodError: ... (LJava/lang/String)
Posted by Bing Li <lb...@gmail.com>.
Dear Martin,
I appreciate so much for your help!
However, I am still confused about the problem. I tried one example as
follows. In this example, a String is sent as a parameter. And then a local
method, getAddr(String keyword), of an object, MyAddress, is invoked. I
noticed that it worked fine.
My case should be the same as that. What I am wondering why such a type
Ljava/lang/String emerged! I never touched that. Moreover, even though I
changed the String to String[], the problem still exists. Really don't
understand why Web services has such a design.
I use POJO to implement my Web services. Could you give me a hand?
Thanks,
LB

RE: NoSuchMethodError: ... (LJava/lang/String)
Posted by Martin Gainty <mg...@hotmail.com>.
it seems that you changed your original input or output message to send array of string to single string or vice versa
if you see the operation SelectCategoriedHubByKey make sure your input and output messages reference the ArrayOfString typed element here is an example

"[Ljava/lang/String;".

I think it is trying to invoke a method with a String[] attribute, not
