Web Service Class Loading + Variables
Hi List,
I'm curious what variables are thread safe when my class (*Impl) is loaded.
More specifically, is my *Impl class loaded for every call? If I have static
class variables, are these not thread safe when Axis processes concurrent
calls to the service? If not, should I be using instance variables, or are
these not safe either? I want variables that are intialized once but
available to any of the publically exposed methods. Where should
initilization of variables be done then? In a constructor, a static block or
does it not matter?
Thanks!
Thunder

Thunder and to anyone else that has sent me a reply....first let me say
that I appreciate the help that everyone is trying to provide and I
hoped I have not ticked anyone off with my stupidity (to and beyond this
point)...
And believe me if you are in the Dallas area and have provided
help...once I get this going I owe you a beer (or my favorite a Crown
Royal and coke)...
But on to the second thing....I tried the command you specified and this
is what happened...
java -classpath $AXISCLASSPATH org.apache.axis.client.AdminClient
deploy.wsdd
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/axis/client/AdminClient
But when I check the path..that class is in the path and it is also in
the axis.jar in the lib directory

Allen,
java -classpath $AXISCLASSPATH org.apache.axis.client.AdminClient
<your.wsdd>
Make sure you have proper permissions to access the axis jars.
This assumes you are deploying to
http://localhost:8080/axis/servlet/AxisServlet
If you are not deploying to the local machine, you need to use the -l
option
and change the default server-config.wsdd which is in the axis jar under
org/apache/axis/server/server-config.wsdd
Personally, I just "jar xvf" extract this file and place it in the
WEB-INF
of my app then modify it here if needed (AdminClient will also modify
this
file). This allows me to configure remote admin, etc. for each web app.

Here's the information that is in my paths:
AXIS_HOME=/opt/WWW/tomcat-4.1.18/webapps/axis
export AXIS_HOME
AXIS_LIB=$AXIS_HOME/lib
export AXIS_LIB
AXISCLASSPATH=/opt/WWW/tomcat-4.1.18/webapps/axis/WEB-INF/classes:$AXIS_
LIB/axis.jar:$AXIS_LIB/commons-discovery.jar:$AXIS_LIB/commons-logging.j
ar:$AXIS_LIB/jaxrpc.jar:$AXIS_LIB/saaj.jar:$AXIS_LIB/log4j-1.2.8.jar:$AX
IS_LIB/xml-apis.jar:
$AXIS_LIB/xercesImpl.jar:/opt/WWW/tomcat-4.1.18/webapps/axis/WEB-INF/cla
sses:
export AXISCLASSPATH
This corresponds exactly to what I have set up. About the
monitor....when I compiled the class I shut the server down and then
restarted it.
On the libraries...I understand that I was just trying other locations
due to me get the ClassDefNotFound error. I have been following the
instructions as they are outlined but I am still have the problems. My
next step was to update my java to 1.4 but I wanted to make sure that it
could not be anything else...
(thanks for the all aboard comment....that was great)...

Bvvvvhhhhh! All aboard...
You must have deployed at least once via AdminClient or ant task to see
a server-config.wsdd.
Was Tomcat running when you started the SOAPMonitor applet?
Your classpath is $#@cked up. Check each entry for path validity.
Axis libraries are delivered in a jar, put it in the right place...this
isn't a classes directory...but a lib directory. I have nothing axis
related in my common/lib or common/classes...my axis/WEB-INF/classes
only has the samples code.
Follow the install instructions to the letter...they work.
