...getting null values
Hi
I have implemented the ServiceLifecycle interface method in my web service implementation class and trying to read some input parameters from my web.xml. But, I don't see the input parameters at all in my "init" method even though I am able to print out other details like the real path to a couple of folders. Any ideas? Would be extremely grateful if somebody can take a quick look at this and help. I looked for typos in the web.xml but couldn't find any. Went to the extent of copying the init parameter section from the "SOAPMonitorService" of the web.xml. Please see below for complete details -
Configuration - Axis 1.1; Tomcat 4.1.27; Java version is 1.4.2.
Output that comes on the console ( web.xml and code snippets are pasted after the output)-
--------------------------------------------------------------------------------------------------------------------
This is the init method of the service implementation-----
parameter names ----
attribute names ---
org.apache.catalina.jsp_classpath
javax.servlet.context.tempdir
org.apache.catalina.resources
AxisEngine
org.apache.catalina.WELCOME_FILES
Getting parameter values......
firstParam null
secondParam null
Misc values extracted from context......
server into Apache Tomcat/4.1.27
real path of / C:\workarea\ebtcWebServices\
real path of /docs C:\workarea\ebtcWebServices\docs
ctx.getMajorVersion() 2
ctx.getMinorVersion() 3
--------------------------------------------------------------------------------------------------------------------
The relevant snippet from my web.xml -
----------------------------------------------------------------------------------------
<web-app>
<display-name>Apache-Axis</display-name>
<servlet>
<servlet-name>AxisServlet</servlet-name>
<display-name>Apache-Axis Servlet</display-name>
<servlet-class>
org.apache.axis.transport.http.AxisServlet
</servlet-class>
<init-param>
<param-name>firstParam</param-name>
<param-value>firstValue</param-value>
</init-param>
<init-param>
<param-name>secondParam</param-name>
<param-value>secondValue</param-value>
</init-param>
</servlet>
----------------------------------------------------------------------------------------
My init method looks like this-
-----------------------------------------------------------------------------------------
public void init(Object context)
{
System.out.println("This is the init method of the service implementation-----");
ServletEndpointContext servletEndPointCtx = (ServletEndpointContext) context;
ServletContext ctx = servletEndPointCtx.getServletContext();
System.out.println("parameter names ----");
Enumeration paramNames = ctx.getInitParameterNames();
while (paramNames.hasMoreElements())
{
System.out.println(paramNames.nextElement());
}
System.out.println("");
System.out.println("");
System.out.println("attribute names ---");
Enumeration attributes = ctx.getAttributeNames();
while (attributes.hasMoreElements())
{
System.out.println(attributes.nextElement());
}
System.out.println("");
System.out.println("");
System.out.println("Getting parameter values......");
System.out.println("firstParam "+ctx.getInitParameter("firstParam"));
System.out.println("secondParam "+ctx.getInitParameter("secondParam"));
System.out.println("");
System.out.println("");
System.out.println("Misc values extracted from context......");
System.out.println("server into "+ctx.getServerInfo() );
System.out.println("real path of / "+ ctx.getRealPath("/"));
System.out.println("real path of /docs "+ ctx.getRealPath("/docs"));
System.out.println("ctx.getMajorVersion() "+ctx.getMajorVersion());
System.out.println("ctx.getMinorVersion() "+ctx.getMinorVersion());
}
----------------------------------
Thanks

ServiceLifecycle params and web.xml init params have nothing to do with
each other.
Service params are configured in your WSDD. Furthermore,
ServiceLifecycle init method will NOT be called if implement it in your
*Impl class. You must implement it in your *Skeleton class (modify the
generated source). If you want your *Impl class to implement it, you
must implement it in your Skeleton then manually call down to the
implementation.
My expectation was that ServiceLifecycle would apply to the *Impl class,
and I would would vote to change this behavior so that is the case.
