[Axis2] Spring/POJO Web Service questions
Hi all,
As part of my current project, I need to expose a Spring Bean as a Web
Service. (I'm new to Web Services.) We're using Axis2 1.5.1.
The project is built with maven2 and produces a war. We want the Web Service
to be part of the Webapp (we do not want to deploy the Axis2 webapp and use
an aar).
I've read the POJO Guide here:
http://ws.apache.org/axis2/1_5_1/pojoguide.html
and the Spring Guide here:
http://ws.apache.org/axis2/1_5_1/spring.html
This page:
http://wso2.org/library/90
also helped me on how to embed an Axis2 Web Service in our webapp.
Good news is that I got something working. But it's not fully working and
there are still a few things not clear to me:
First, I haven't written a WSDL file. Only a services.xml. But when I reach
the URL:
http://domain/services/myService?wsdl
...I do get a WSDL. So I guess it's generated by Axis2 based on the
services.xml and on the bean itself. My first question is: is it a good way
to go? Or should I write a WSDL?
My second question is about the parameters we can or cannot use in web
services:
The interface of the bean exposed as a web service looks like:
public interface MyService
{
String getName(String name);
MyObject createMyObject(Map<String, String> properties)
MyObject updateMyObject(MyObject object, Map<String, String>
newProperties);
MyObject removeMyObject(MyObject object);
}
and the MyObject class is:
public class MyObject
{
public enum Status {
Success,
Error,
Invalid
}
private Status status;
private long id;
private String field1;
private String field2;
// + getters and setters for each field
}
With my Web Service client (which uses an RPCServiceClient), I can call the
String getName(String name) method successfully, but not the other ones.
I have 2 problems with the other methods:
First, they are using Map<String, String> as parameters. I read a lot of
posts about that and it seems using java specific classes in web services is
not a good thing since web services are supposed to be platform/language
independent.
But I know for sure that my project will be 100% Java, so I'd like to use
Maps anyway. And since the posts I read were quite old, I was wondering if
there is now an easy way to do that? Maybe using JiBX ? Would it be
compatible with a POJO/Spring web service?
Second, I have a problem with the serialization of the MyObject class: I get
an error related to the status field. The error says something like "Status
type has no constructor...." Anyone know about that?
Last thing, I'll have to make this web service secure. Is Rampart the way I
should go? Can I integrate it with a POJO/Spring web service?
Any help would be much appreciated!
Thank you,
Phil.

indeed, the Deployer is responsible for setting up a wsdl, so you do not

Thank you guys for your replies.
I'm now using arrays instead of the maps and the ordinal value of the enum
instead of the enum itself. Everything works fine.
Regarding security, https is what I want, indeed. I'm currently trying to
set up mutual SSL authentication...
Thank you again,
Phil

I am using the trunk, in a version I found on Thursday, namely svn r953088
though, i cannot remember where i got it; the site
(http://ws.apache.org/axis2/svn.html) has a wrong location where nothing
is to be found anymore; I believe that I got it from
https://svn.apache.org/repos/asf/axis/axis2/java/core/trunk/

I am not using a settings.xml
maven is
Apache Maven 2.2.1 (rdebian-1)
Java version: 1.6.0_18
Java home: /usr/lib/jvm/java-6-openjdk/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux" version: "2.6.32-22-generic" arch: "i386" Family: "unix"
furthermore, I am still positive about the java.net issue. from the list
in /modules/parent/pom.xml , some modules can no longer be found.
the last attempt is made to http://download.java.net/maven/1 , which
contains a couple of jars, but only 404s for others; these maven
downloads and notices a checksum error, but keeps the artifacts in the
repo anyway to produce misleading unzipping errors ( :-( ). I put the
central repo in place of these, and got most jars but had to manually
install some snapshots of FastInfoset, woden and neethi (in the latter
case, I do not know why a 3.0.0-SNAPSHOT is sought after; I chose to
just register the latest 2.x.y release under that name for want of a
better idea). This left me at where I am now, with javac complaining
that it cannot find org.apache.xerces.parsers.DOMParser ,which is in
XercesImpl I tried to just put that into the repo as well with the
group id I found on jarvana, put maven would not find it. I notice that
more invalid stuff is to be found further up in the build process
(kernel module)
[WARNING] POM for 'org.apache.maven:maven-profile:pom:2.0.1:runtime' is
invalid.
Its dependencies (if any) will NOT be available to the current build.
[WARNING] POM for 'org.apache.maven:maven-model:pom:2.0.1:runtime' is
invalid.
Its dependencies (if any) will NOT be available to the current build.
[WARNING] POM for
'org.apache.maven:maven-artifact-manager:pom:2.0.1:runtime' is invalid.
Its dependencies (if any) will NOT be available to the current build.
[WARNING] POM for 'org.apache.maven:maven-artifact:pom:2.0.1:runtime' is
invalid.
Its dependencies (if any) will NOT be available to the current build.
but I have no idea what they relate to. I am feeling quite swamped by
errors here, so if it is just some repositories that one of the
developers has noticed to be missing, it would be nice if you could
update these.
the ant build does not make me much happier either; after successfully
installing the mar and aar plug-ins, it ultimately fails missing the
same class.
In any case, the tests fail quite sometimes; should the suite pass in
its entirety?
so, any help appreciated

For the Axis2 trunk, no particular set up is required for java.net.
This is only required when building previous release tags.

Clear your local maven repository, check that your settings.xml file
doesn't contain any esoteric settings, check that you don't have an
HTTP proxy that blocks stuff, and then restart the build. If that
doesn't help, please report the Maven version you are using.

Problem with maven dependency
Posted by Jan Sinschek <su...@gmx.net>.
Hi,
when I try to build axis2 from the current trunk, (mvn install) I
eventually get
>java.lang.NoClassDefFoundError: org/codehaus/plexus/util/DirectoryScanner
So, after looking into the matter unsuccesfully, I scraped part of my m2
repository and found myself in the same situation. Also, corrupted
ressources are still being downloaded from java.net, which has already
been "fixed" by someone making a statement in jira issue about how to
distract maven from using that site; however my problem with plexus
comes up regardless.
I am not sure what's the best thing to do about this: where should I get
plexus? And which module is really missing?
The following shows the last of my downloads before the failure; I do no
really see how all the outputs relate; I would normally try to find
another alternative repository for plexus- some downloads already, use
the fourth fallback to get the jars they _do_ obtain- but as I cannot
find the current repository's location, "ws.zones.apache.org", I cannoti
mage what to change in the pom to get the alternative download location

IMHO you don't need your own wsdl.

IIRC, The axis2 java collections pojo support is spotty. I don't
remember if Map is supported or not. My recommendation is to send
arrays, and use the java api for things like Arrays.asList() to
convert to your app level needs,

Not sure on this one. Try adding a no-arg constructor.

In many cases just using https is sufficient.
