Info:

<message-resources parameter="ApplicationResources" factory="MyOwnFactory"
class=MyOwnConfig"

<set-property property="xProp" value="xValue"/>
</message-resources>
MyOwnFactory extends PropertyMessageResourcesFactory
MyOwnFactory instansiates MyOwnMessageResources
MyOwnMessageResources extends PropertyMessageResources
MyOwnConfig extends MessageResourcesConfig
MyOwnConfig has a property called xProp


Problem:
How can my class MyOwnMessageResources access property in MyOwnConfig ?
Is there a static method somewhere in Struts api ?

Hi there,

I have a question concerning validator framework:

If have the same attribute for example salary in two forms is there any possibility
to define the validation rule in one place.
So that my form-field can depend on that rule.

regards


<form-validation>
<formset>

<form name="userFormVF">
<field property="userId" depends="required">
<arg0 key="prompt.userId"/>
</field>
<field property="salary" depends="double">
<arg0 key="prompt.salary"/>
</field>
</form>

<form name="userFormDVF">
<field property="userId" depends="required">
<arg0 key="prompt.userId"/>
</field>
<field property="salary" depends="double">
<arg0 key="prompt.salary"/>
</field>
</form>
</formset>
</form-validation>

Environment:
J2EE 1.3
WebSphere Studio Application Developer (Windows)
Version: 5.1.1
===================================================================
Title: Connection to JMS from J2EE-Client
===================================================================
Hi there,
Have a couple of questions:
1: In my deployment descriptor for the j2ee-client,since I want to make a call to
JMS, I need to create references to QueueConnectionFactory and Queue.
How should I declare them as resource-references or resource-environment-references ?

2: I tried to declare them as resource-references, but I'm not sure how I do a
proper lockup.
When I do a lockup I get a reference to a "Reference-object" which I can't cast to a Queue for example.
How do I get a handle to the Queue and QueueConnectionFactory ?
*** My lockup locks like this:
String jndiQueue = "java:comp/env/jms/myOeeQueue";
Object obj = ctx.lookup(jndiQueue);
Is there a better way to do a lockup from the client ?
regards

Hi All,
My environment: wsad 5.1.1 J2EE 1.3
I'm trying to run this scenario for test purpose:
Servlet -> Messaging Bean -> EJB Session bean
The servlet starts the the Messaging Bean using a Connection factory and queue.
In the web-deployment descriptor I have declared them as refererences.
This works fine.
I get the messaging bean to start, but then I get an exception in messaging bean
doing lockup for the Session Bean.
In the EJB deployment the 2 EJB beans are declared.
I'm confused over how I should do a lockup to the session bean from the messaging bean
1. Should I create a new InitialContext ?
Context ctx = new InitialContext();
2. I have tested with this:
Context ctx = new InitialContext();
String name = "ejb/jmstest/ValidationBeanLocalHome";
Object objref = ctx.lookup(name);

and this:
Context ctx = new InitialContext();
String name = "java:comp/env/ejb/jmstest/ValidationBeanLocalHome";
Object objref = ctx.lookup(name);

Help regarding this deeply appreciated.

Hi,
The problem is this:
When I deploy different Java applications, it could be war applications,
ordinary application, in most cases it's practical to use a propertyFile
so that the properties are not hardcoded.
Sometimes I want to deploy the application to Windows and sometimes it could be Unix.
I'm using ant as a deployment tool...
The problem is that I do not want to hardcode the location of the propertyFile.
One idea would be to:
- create a text file "propertyFileLocation.txt" where the location is edited
- put that file in the jar file
- and have the application to read the location from the jar
Does anyone have a better idea ?
thanks in advance,

Hi,
Question about gregorian date...
I initialize a GregorianCalendar to the 4th of January of 2005 like this:
Calendar newCal = new GregorianCalendar(2005,0,4);
System.out.println("Week is =" + newCal.get(Calendar.WEEK_OF_YEAR));
it prints out
Week is =2
The problem is that the 4th of January of 2005 actually is week 1.
What am I doing wrong ???

Hi,
I have a ServletA that forwards requests to ServletB.
ServletA reads a file as a stream and that stream should be passed to ServletB as
inputStream. How can this simpliest be achieved ?
I know that ServletA can open an urlConnection and write to that ?
Is that the only solution ?
thanks in advance

Hi,
From an Java-application I want to call a servlet with a post request that includes a text-file
in the inputstream.
How do I do that ? I tried the following,but I'm confused about how the servlet can read the stream .
URL url = new URL("http://plovdinger:80/xmlReceiver");
URLConnection uc = url.openConnection();

uc.setDoOutput(true);
OutputStream os = uc.getOutputStream();

OutputStream buf = new BufferedOutputStream(os);
OutputStreamWriter out = new OutputStreamWriter(buf,"8859_1");
out.write("one little line\r\n");
out.write("Two little line\r\n");
out.flush();
out.close();

//return the response
readInputStream(uc.getInputStream());

Hi,
In a http scenario I want to communicate between 2 system sending and receiving xml-files over the internet:
So that the request should include one xml-file and the response should include one xml file.
What is the recommended mechanism to include xml-file content for a request ?
- As parameter ?
- As inputStream with character data ?
- some other way
What is the recommended mechanism to include xml-file content for a response ?
- As outputStream with character data ?
- some other way

Hi,
When parsing a big xml-document using DOM I get
a OutOfMemoryError.
I'm using apache.xerces as parser.
I read that a "deferred DOM" might solve the problem.
What is the syntax in xerces to use a "deferred DOM" when I parse ?
