Question

Hi,
Iam getting the following EXCEPTIONS while deploying my war file.
Iam getting this exception………………in the log file too.
<Jun 23, 2004 3:05:14 PM EDT> <Error> <HTTP> <BEA-101018> <[ServletContext(id=19521401,name=myPortal,context-path=/myPorta

I think the code that is causing the problem is due to one JSP that has the following
CODE ::::
<%
try{              
String rootPath = this.getServletConfig().getServletContext().getRealPath("/");
// get the config file property value
String settingsFile = this.getServletConfig().getServletContext().getRealPath("/WEB-INF/config/ApplicationSettings.properties"
// is the above code will work ?????
// i suppose this will give javax.servlet.ServletException: Unable to resolve
location....
// is the following code could create singleton problems .....
Resources.Instance().load(settingsFile); configFile = Resources.Instance().getResource(RESOURCE_KEY);
// load the properties
File fileObj = null;
fileObj = new File(rootPath + configFile);
xmlContainer = new XMLDataContainer();
xmlContainer.load(fileObj);
// get the element names and their values.
names = xmlContainer.getElementNames();
if(names.isEmpty())
noElements = true;
else{           
noElements = false;
elemIter = names.iterator();
%>
PLEASE TELL ME, WHAT THE PROLEM IS ???
we are using wls8.1+ sp2.

Rob,
2 questions:
1) You told me this:
"foo.xml in the same directory"
Here, what do you mean by "in the same directory" ????I meant deploy /foo/myApp/myWar.war and /foo/myApp/myConfig.xml
>
2) why do you want foo.xml to be separate from the deployment unit....what is
the reason ??I'd want to separate the configuration from the application code. If
you find a bug in your app and rebuild it, you're going to have to merge
in any changes you've made to your configuration file.

No, I'd suggest having it external to the deployment unit. ie deploy
foo.war and have foo.xml in the same directory.

sangita wrote:
do you suggest taking this config out from the .war file and put itinto a .jar
file, and then package the .war and the .jar file together into an.ear file.

Rob Woollen <[email protected]> wrote:
It is possible to write back to a zip file, but I wouldn't encourage
it.
If you need to update the config file, I'd suggest that you either
deploy exploded, or keep the config file external to the war file.

Rob,
You told me a workaround to read the configuration file in a .war
file.
That is
done and iam experiencing no problems.
BUT i also need to write back some changes to the configuration file,how can
i do that ???
Iam getting exceptions and it looks like the weblogic container doesnot handle
this. some protocol exceptions.
please let me know.
thanks, sangita

Rob,
what is the following means ??
Otherwise, using getResourceAsStream to get an InputStream would
work
as well.
Please explain a little more.
thanks again.

No, neither of these would be bugs. getRealPath is supposed to
return
null for archives.

Rob,
would that mean that this is a bug in WLS8.1+sp2 ???
Rob Woollen <[email protected]> wrote:
getRealPath will return null if the war is archived rather than
a
directory. The easiest solution would just be to deploy an
exploded
war.
