Re: [Axis2] A hello World Example for Axis2 deployment
Hi Anil, A few days ago, I submitted a message on the mailing list about the problem to display the WSDL in the browser, with Axis2.1.2. The full message is there: http://marc.info/?l=axis-userm=117915706112761w=2 It seems you have found the solution for this problem. Could you tell me how you solved the problem ? Thanks in advance.

What we first need to know is: Does your Tomcat servlet container work properly? Forget about the AXIS WAR file--first run the Tomcat servlet and JSP samples installed by default (at http://localhost:8080)--are http://localhost:8080%29--are you getting the same/similar errors below, or is everything running fine? If the former, forget about Axis and go to the Tomcat user list until the Tomcat samples are working. If the latter, then the problem is with the tutorial you are using, again you may need to switch to another, or read three or four tutorials until you can get things working. Keep working at it. Yet another option for you might be the quickstart guide: http://ws.apache.org/axis2/1_2/quickstartguide.html. Finally, if you ever figure out what the problem was with the WSO2 article--assuming there was a problem with it--please email the author privately letting him/her know so the tutorial can be fixed. This way future newbies won't have to experience the same troubles.
Re: [Axis2] A hello World Example for Axis2 deployment
Could you possibly be using the (older) Crimson parser instead of Xerces? IIRC Crimson has problems with namespaces--which may account for the error that you are getting. I believe Crimson is the default with JDK 1.4. In addition, to simplify your problem, you may wish to run the simple POJO example on the quickstart page[1] and see if you can get the WSDL to appear with *that* example. If not, I would forget your code for the moment and instead concentrate on getting the simple POJO case to work.

Hi
Another newbie question. In the tutorial http://wso2.org/library/95;
. The axis2-std-SNAPSHOT-bin distribution comes with a bin

which contains a Linux shell script and a Windows batch file to start
the SimpleHTTPServer: http-server.sh and
Re: [Axis2] A hello World Example for Axis2 deployment
Anil,
Sorry you're having so many difficulties. Perhaps the tutorial you are
using--and I had previously suggested, alas--isn't very good, as you are
having too many problems getting it to work. A newbie-level tutorial
should not be causing that much difficulty--it should be making things
easy for you. There are more tutorial options--just by looking at the
list I had given you, or googling axis tutorial, may help.
But what I'm also seeing is that more detective work is needed. What we
first need to know is: Does your Tomcat servlet container work
properly? Forget about the AXIS WAR file--first run the Tomcat servlet
and JSP samples installed by default (at http://localhost:8080)--are you
getting the same/similar errors below, or is everything running fine?
If the former, forget about Axis and go to the Tomcat user list until
the Tomcat samples are working. If the latter, then the problem is with
the tutorial you are using, again you may need to switch to another, or
read three or four tutorials until you can get things working. Keep
working at it. Yet another option for you might be the quickstart
guide: http://ws.apache.org/axis2/1_2/quickstartguide.html.
Finally, if you ever figure out what the problem was with the WSO2
article--assuming there was a problem with it--please email the author
privately letting him/her know so the tutorial can be fixed. This way
future newbies won't have to experience the same troubles.
HTH,
Glen

Re: [Axis2] A hello World Example for Axis2 deployment
Glen
Thanks for taking time out to explain everything. I did validate the tomcat
install before and executed the sample JSP applications. I am using Tomcat
5.5 instead of Tomcat 6.X as that is present on my deployment box. Can this
be an issue.
Thanks

Re: [Axis2] A hello World Example for Axis2 deployment
No, I don't think so. 5.5 should be fine.
Go back and place the axis2.war file into the Tomcat webapps directory.
Can you access and log into the Axis2 Admin URL at
http://localhost:8080/axis2/axis2-admin? (userid/pwd: admin/axis2)?
For available services, does it show the Version service?
The above is the next step to make sure is working correctly before
worrying about the service archive (.aar) file.
If the above is working correctly, try deploying your service archive
(.aar file) using the admin app above instead of directly placing it in
the webapps/axis2 folder.
