>> File destination = new File(context.getInitParameter("TREND_JDBC_FAULT"));

If you are getting parameters from the ServletContext, they need to be defined as <context-param>s in web.xml, which precede any <servlet> elements.

 

To get a servlet's <init-param> you would need a reference to the Servlet object itself.

 

Hope this helps

Subject: trying to access ServletContext within axis webservice

Hi,

I am trying to access <init-param> values from within my axis webservice like so ..

...

import javax.servlet.ServletContext;
import javax.servlet.http.HttpServlet;

import org.apache.axis.transport.http.HTTPConstants;
import org.apache.axis.MessageContext;

...

public class MyWebService(){

...

        HttpServlet srv = (HttpServlet)MessageContext.getCurrentContext().getProperty(HTTPConstants.MC_HTTP_SERVLET);
        ServletContext context = srv.getServletContext();
        File moveFile = new File(fileLocation);
        File destination = new File(context.getInitParameter("TREND_JDBC_FAULT"));
        boolean fileMoved = moveFile.renameTo(new File(destination,moveFile.getName()));

...

}

however I am catching and logging the error as this does not seem to work for me,

java.lang.NullPointerException
        at java.io.File.<init>(File.java:180)
        at com.leocate.spreadSheets.ExcelPublishingService.createSpreadSheet(ExcelPublishingService.java:49)

I put my <init-param> in axis/web-inf/web.xml

<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>TREND_JDBC_FAULT</param-name>
                        <param-value>\System_Path\</param-value>
                </init-param>
        </servlet>

I am just wondering if I am doing everything correctly,
I am using apache tomcat 4.01, axis beta 1,

I had a look on how to do this on the apache site and this is the Axis specific approach to getting the
ServletContext,

any advice would be appreciated,

thanks jp.
