Got a question to be answered on Axis2? Then this document is just what the doctor ordered.
Any other doubts/issues e-mail your questions to:
Prefix subject with [Axis2]. To subscribe to mailing list see here.
First make sure you go through user guide and this FAQ. If you are using a released version of Axis2, then there is a possibility that your problem has already being fixed in the latest code. Download Axis2 nightly builds from here and test again with it.
If the problem still persists then try to search for your question in our developer or user mailing archives as it might have already being answered.
If your problem is not answered in the mailing list, now it is the best time to post your question to axis-user mailing list. If you think it is a bug, please fill a bug report in JIRA. Please attach all the supportive information, like your wsdl, schema, clients, services, stacktraces, etc., to the JIRA issue you created, as it will help one of our contributors to re-create the problem. PLEASE DO NOT ASK QUESTIONS USING JIRA AND USE IT ONLY AS A ISSUE TRACKER.
If you are asking for an explanation of a feature in Axis2, there is a possibility that there is an article or FAQ written on it. Please do a search on the web as there are lot of article written and hosted by various sources on the web.
Note : When you ask questions in the mailing list, please remember that everyone working in our project are volunteers. No-one can be forced to fix your bugs (check here).
Make sure you add enough information about your problem with stacktraces and any other supportive information. It will improve the chances of your question being answered. Prefixing your mail subject with prefixes like "URGENT" will not help you in any means. Yes we also accept all the blames about Axis2 in these mailing lists, as those will definitely help us to improve Axis2 :) .
You have to add Bouncy Castle as a JCE provider. Add the following entry to java.security file of the appropriate JRE on your machine. This file is available in the lib\security\ directory within the JRE directory.
security.provider.7=org.bouncycastle.jce.provider.BouncyCastleProvider
security.provider.# will have to be decided depending on the existing entries in the java.security file
NOTE: For Windows XP the correct version can be found using 'java -version'. The correct file is JRE (typically c:\Program Files\Java\jre<version>\lib\security\java.security.
You have to copy the stax-api jar in the axis2 distribution into your JRE's endorsed directory (see info on endorsed directory here - http://java.sun.com/j2se/1.4.2/docs/guide/standards/).
This issue can also be resolved by copying the stax-api jar to tomcat's common/endorsed folder, when deploying Axis2 in tomcat,
Axis2 has the notion of service isolation where each service or module gets its own class loader. Using this class loader you can access any resource that you put into your service archive file. You may want to access your resources from different locations. For example,
1. A third party module wants to access your resources, then the scenario is as follows:
AxisService myService = messageContext.getAxisConfiguration().getAxisService("serviceName");
or
AxisService myService = msgCtx.getAxisService();
Then you can ask for service class loader using which you can access its resources
ClassLoader clsLoader = myService.getServiceClassLoader(); clsLoader.getResourceAsStream("myResource");
2. To initialize service implementation class at the MessageReceiver level the following steps need to be taken
AxisService service = msgCtx.getAxisService(); ClassLoader clsLoader = service.getServiceClassLoader(); Class.forName("serviceName",clsLoader,true);
NOTE : Axis2 default MessageReciver uses the same technique to initialize service implementations
3. If you want to load your resources at the service implementation class then the scenario is as follows
getClass().getClassLoader().getResourceAsStream("myResource");
Look at the ServiceClient class, for more information please read the User's Guide
From Axis2 0.94 onwards, both request-response and one way messaging will be handled by ServiceClient.
useSeparateListener=trueI get the error to do two Transport Channels the Addressing Modules must be engaged, Why is this?
To do the two transport Channel invocation you need to engage the addressing module. You can enable it by un-commenting the entry in the axis2.xml file or Call.engageModule(QName). But addressing is enabled by default.
If you have engaged addressing , then you have to have wsa:action, the required WS-Addressing header. so you have to call
option.setAction("urn:myaction");
It should be not that the action should be a URI.
Repository stores the configuration of Axis2, the users should specify the repository folder starting the Axis Server (HTTP or TCP). In the case of tomcat it is the webapps/axis2/WEB-INF folder. Following picture shows a sample repository.
Modules and services have a archive format defined and they are automatically picked up by Axis2 when they are copied to corresponding folders.
Axis2 requires itest plugin to run some of the tests. Better get it using following command.
I have problems building with maven
1.1 ....
It seems that maven 1.1 doesn't come bundled with the required
artifact plugin. Run following to get it updated
You may need to update the itest plugin too, using the above command in #1.
What versions of maven are supported?
....
Versions 1.0.2 and 1.1 are supported. Maven2 as of yet is not supported.
Command
|
Description
|
---|---|
maven
|
download relevant jars, if not available and compile and run tests
of the system.
|
maven clean | Clean all the stuff build so far, that are in the target folder. This will not clean the jar repository |
maven test
|
run only the tests. Will do automatic compilation of changed
sources as well. This will not run soap interop tests
|
maven clean all-tests
|
Clean up and run all off line and on line tests
|
maven itest
|
To run the online-mode tests for say the modules/integration Run
"maven itest" from modules/integration
|
maven test itest
|
To run all tests for say the modules/integration Run "maven
test itest" from modules/integration
|
maven -g
|
List down all the commands available with maven
|
maven multiproject
|
generate this site
|
maven idea:multiproject
|
generate IDEA .ipr, .iml and .iws project files
|
maven -Dmaven.test.skip=true
|
Builds Axis2 and skips all the tests |
maven dist-min-bin | Will generate the binary version of Axis2 minimal distribution |
maven dist-min-src | Will generate the source version of Axis2 minimal distribution |
maven dist-std-bin | Will generate the binary version of Axis2 standard distribution |
maven dist-std-bin | Will generate the source version of Axis2 standard distribution |
maven release | Generate all the distributales for Axis2 |
maven clean jar -Dmaven.test.skip=true -o | This will clean all the target folder and compile your source, without running the tests or downloading snapshots of dependancies. This is the quickest way of compiling Axis2 sources. However it is highly recommended to run the tests all the time |
It's just a matter of writing a services.xml file to configure the service or services in an archive file. The corresponding services.xml SHOULD look like below:
<serviceGroup> <service name="myService1"> ........................... </service> <service name="myService2"> ........................... </service> <serviceGroup>
NOTE : The name attribute is a compulsory attribute which will become the name of the services. But if you want to have one service in the archive file then there are two options, either have one service inside serviceGroup tag or have only one service tag as shown below in your services.xml, in which case, name of the service will be the name of the archive file and you can not override that.
<service> ............... <service>
This happens specifically with tomcat 4.x and 5.0 in a JDK 1.5 environment. The reason is that the system picks up a wrong transformer factory class. This can be solved simply by putting the xalan-2.7.0.jar (found here) into the axis2/WEB-INF/lib directory
WSDL 2.0 is not supported yet. We do not have a working WSDL 2.0 reader.
However the codegen engine works off WOM (not WSDL4J) hence if the WSDL 2.0 reader is done, we are all set to generate code for it.
And yes, it is perfectly possible for the codegen to generate code for the HTTP binding. We already have the client API support for making the REST calls and it should be a matter of putting in a correct template.
