A remote debugger can then be attached by connecting to port Whichever the distribution, installing Axis2 in a J2EE compliant servlet container is as follows:. Note: For any Application server specific installation information please refer to the Application Server Specific Configuration Guide. The Axis2 Web application also provides an interface to upload services. Once a service archive file is created according to the service specification as described in the Advanced User's Guide , that.
The uploaded. Once a service is uploaded, it will be installed instantly. Since Axis2 supports hot deployment , you can drop the service archive directly through the file system to the above mentioned services directory. It will also cause the service to be automatically installed without the container being restarted.
Use the 'Services' link on the Web Application home page to check the successful installation of a service. The services and the operations of successfully installed services will be displayed on the available services page. If the service has deployment time errors it will list those services as faulty services.
If you click on the link, you will see the deployment fault error messages. Axis2 Administration is all about configuring Axis2 at the run time and the configuration will be transient. More descriptions are available in the Axis2 Web Administration Guide. Required jar files do not come with the distribution and they will also have to be built by running the maven command.
Before we go any further, it is necessary to install Maven2 and set up its environment, as explained below. The Axis2 build is based on Maven2. Hence the only prerequisite to build Axis2 from the source distribution is to have Maven installed. Extensive instruction guides are available at the Maven site. This guide however contains the easiest path for quick environment setting. Advanced users who wish to know more about Maven can visit this site. This is to access. You must have openssl installed in you system.
Add following entry either to axis2. Then add following Security phase to the phase order in the inflow and outflow in the axis2. To specify policies in the client side, please drop your policy. To specify policies in the server side, please add policy assertions to the services.
Note that you must replace both the client and service policies for a particular scenario. This release comes in two forms, source and binary and you can download them from here. This document covers both forms. Please send your feedback to the developer mailing list: c-dev axis. Please remember to prefix the subject with [Axis2]. To write your own services or clients this is not a requirement.
These are optional. Just double click it and everything will be set to the defaults. In that case, the module.
Sometimes a module may define its own phase. In that case, some of the module specific handlers may be put into that phase.
The handlers added to the system predefined phases global handlers are invoked for every message that comes to or goes out from the system. The handlers in the module specific phase are invoked only for the messages invoking the operations that engage that module. Engaging a module means correctly adding the handlers of a particular module to one or more phases.
Once the module is engaged, the handlers and the operations defined in the module are added to the entity that engaged them. In the module. Below is the module. In the above shown module configuration file, the name of the module is logging. The LoggingOutHandler is placed into the MessageOut phase of both the out flow and the fault out flow.
The above module. The module libraries containing the handler implementation should also be copied to the same folder. According to the module. Module specific phases have to be added after the system predefined phases. The following example shows where to add the module specific phases. Look for the phaseOrder elements in the axis2. Note the comment lines:. You can add user defined phases after the above comment line into any of the flows.
The type attribute of the phaseOrder element indicates the flow. For the logging module example, user defined phases are not required. All the module specific handlers are added to system predefined phases as specified in the module. The following is an example of engaging the logging module to the echo service. The handlers inside the module will be executed in their respective phases as described by the module.
One important thing to note here is that because the logging module's handlers are placed into the global phases, even though the logging module is engaged only to the echo service, the module will be engaged globally. This is a feature of the Axis2 architecture, not a bug. When invoked, the handlers in a module can check whether the module has been engaged to a particular service, and act accordingly. If only a particular client wants to engage the module, it can be done by engaging the module programmatically.
This can be done by adding the following line in the client code after setting the options. Remember to replace "module-name" with the name of the module you want to engage.
For example to engage the logging module you can use:. WS-Addressing provides mechanisms to address Web services and messages. Hence as explained in the previous section, the addressing module can be engaged both on the client side as well as on the server side.
The WS-Addressing module can also be programmatically engaged using the following line of code with the service client API. If the addressing module is engaged, there are no options to be set on the server side. That is to set a WS-Addressing action that represents the operation to be invoked. In addition to the action, which is mandatory, there are other WS-Addressing related headers that can be sent in a message.
The following functions are used to set them. Sets the wsa:ReplyTo header. The ReplyTo header contains the endpoint to send reply messages.
The ReplyTo header is required when the response comes in a separate channel when using a dual channel. Sometimes the receiving endpoint requires to know the original sender of the message. The wsa:From header is used in such cases. The above function sets the From header. Sets the wsa:RelatesTo header. This header contains a unique ID which is the message ID of a previously exchanged message.
It helps to identify a previous message that relates to the current message. A SOAP message can contain any number of header blocks. These header blocks provide various processing information.
Some times modules may add header blocks to a SOAP message. Normally a module is a collection of handlers. So writing a module mainly consists of writing handlers.
There are two interfaces that are important when writing a module. The in handler and the out handler that deals with logging along with the in-flow and out-flow respectively. The engine can have two flows, the in-flow and the out-flow. A flow is a collection of phases, and a phase in turn is a collection of handlers.
A handler is invoked when the phase within which it lives is invoked. The invoke is called to do the actual work assigned to the handler. The phase that owns the handler is responsible for calling the invoke function of the handler. The implementation is similar to the in handler, except that it is placed along the out-flow when deployed.
After writing the module, the module. Please see the sample module. Please see the Engaging a Module section for more details on how to package and deploy the module. On the MS Windows platform, you have to provide the Apache2 install location in the configure. If you are using Apache 2.
NOTE: To execute some of the commands given below, you might require super user privileges on your machine. Edit the Apache2's configuration file generally httpd. Please note that you have to fine tune the above settings to mach your system.
Note that repository path should have read access to the daemon user account under which the Apache2 HTTPD process is run. Note that the log file path should have write access to the daemon user account under which the Apache2 HTTPD process is run. These log levels have the following meanings:.
This is optional and defaults to "services". You have to give the size of the shared global pool in MB. If you doesn't set the value or if you set a negative value Apache module doesn't create shared global pool. Then you should be able to run clients against this endpoint. If you are using the makefile to build the source, you have to run the command.
The value can be either trace , error , info , critical , user , debug , or warning. Just double click it and everything will be set to the defaults. If you want to change the values you can manually edit the the. We recomend the manual editing as it is the easiest way to specify the values. Then you can start building with SSL client support. Such a file which contains both the certificate and relevant private key is called a certificate chain file. Creating such a file is very easy. Assume that the client certificate is stored in a file named client.
Then the certificate chain file can be created by concatenating the certificate file and the private key file in that order, in to another file, say client. On MS Windows, you can do this by copying the contents of client.
Uncomment the following in axis2. If you need client authentication, you can also set the parameters in the axis2. Parameter names for these are:. For testing purposes, you can use the server's certificate instead of the CA certificate. On Linux, if you run the following piece of code, the server certificate will be saved to a file cert.
NOTE: Instead of setting these parameters in the axis2. In the httpd. When using proxy authentication, there are three methods for specifying proxy authentication settings:. You can specify proxy authentication settings using the following function with the service client:. You can specify proxy authentication settings using the following function with the service client options:. Leave this field NULL if you are not forcing authentication.
You can also predetermine whether proxy authentication is required. This can be done by calling the function below:.
