In my web application I use JBoss Application server.
I've defined datasource parameters in jboss-config.xml.

Thanks.

Compare creation of Datasources and JMS Queues : SAP vs (Weblogic/Websphere

I am used to creating JDBC Datasources and JMS Queues on Weblogic/Websphere thru their Admin applications.
Can someone compare/contrast that process to that on SAP's netweaver ( either using NWA or Visual Administrator).
Thanks

Hi Parag,
For the process of creating JDBC datasources and JMS resources @ SAP NetWeaver you can refer to the documents here on SDN and help.sap.com, and compare that process for yourself, thus not being influenced by others' biased or unbiased opinions.
For NetWeaver 04 and 04s these would be:

How to get bundled message resource in validation.xml?

Hi,
Is it possible to get a bundled message resource in the validation.xml? Basically i want to do the following validation:
<form name="testForm">
         <field property="name" depends="required">
              <arg0 key="form.testForm.name" />
         </field>
</form>But the message "fom.testForm.name" is stored in a resource file stated as below in struts-config.xml:
<message-resources parameter="com.test.TestResources" key="test"/>Means if u want to use this message in jsp, u need to add bundle="test". In this case, how to write the validation? Possible to get this message?

u can give your message key value pair the default
application resource bundle..Do u mean that here i could only use default application resource messages? Other resource messages could not be used for validation?

Struts message-resource problems in jboss

Hi,
I'm fairly new to jsp/servlets and I'm trying to use the struts framework.
I have a html file with the struts bean taglib defined and the following line :
<bean:message key="index.title" />
In struts-config.xml I have the following :
<message-resources parameter="MyAppResources" />
And I put MyAppResources.properties in WEB-INF/classes
I then add the files to myapp.war and deploy it in jboss, but when I try to load the page I get the following exception :
javax.servlet.ServletException: Cannot find message resources under key org.apache.struts.action.MESSAGE
Any help would be greatly appreciated!!!

and if, after deploying, you delete the war file? Does it work then?
Problem seems to be that in a war file the directories arent as the class loader expects them, I think.

Struts question - message-resources

Hi,
I'm trying to do someting which should be pretty straight forward, but can't figure it out. In my application.properties file I have a setting. (DEBUG = true). I can spit this value out in my jsp easy enough using
<bean:message key="DEBUG"/>
But what I want to do is be able to decide in the jsp (using some logic) if the flag is set to true, then show some hyperlinks (for debugging purposes).
What I kinda want to do is this (i know this doesnt work)....
<logic:equal name="message?" property="DEBUG" value="true">
<p>debug mode</p>
.. print some stuff
</logic:equal>
Obviously I'm not getting a handle to a bean here & thats why it doesnt work. But is there a simple way to do this. I dont want to code this property into into a bean - there must be some way of doing it.
I was looking around on the web and found a site where somebody mentioned that a "messages" bean is created and put in the session. If this is true then I could possibly get the above syntax to work, but I dont know how to get the name of the bean - (message doesnt work)
Any help would be greatly appeciated
Paul

I don't think the logic tags are tied into struts like the bean and html tags. The only way I know of is to get the message resources the hard way...
<%
MessageResources mr = (MessageResources)application.getAttribute(Globals.MESSAGES_KEY);
Locale locale = (Locale)session.getAttribute(Globals.LOCALE_KEY);
pageContext.setAttribute("DEBUG", mr.getMessage(locale, "DEBUG"));
%>
<logic:equals name="DEBUG" value="true">
That should work, I think.

Weblogic datasource - Created "1" resources for pool "DataSource", out of which "1" are available and "0" are unavailable.

I am performing some transactions with java application deployed on weblogic. I faced some issue of getting the transaction response with some delay. I found these below mention messages logged into the managed server logs.
Following is my datasource settings

i know this,
The cause of the problem is: owing to the client's operations staff to modify the datasource ,and reployed

[Struts] Presenting errors and messages in a neat fashion

I need to write a piace of jsp code that will present the errors and the messages to the user.
The errors (if any) must appear under a small title "errors" (error.title in Message Resources), while other messages (if any) will appear under the title "messages".
I found a piece of code, that already works, for showing validation errors:
<logic:messagesPresent message="">
   <font color="red"><bean:message key="error.title"/></font><br/>
   <html:messages id="message">
     <html:img page="/view/images/arr_right.gif"/><bean:write name="message"/><br />
   </html:messages>
</logic:messagesPresent>But I don't know how to have it 'recognizing' the difference between messages and errors, and how to present them appropriately.

Maybe you can't like that. Instead of it, you need to create the script using the command like "grep".

Resources for designing data types and message types

Hi
I wanted to know if anyone can recommend me some good resources which can explain the design considerations for designing data types and message types in XI which can help promote reusability.
Thanks.
Best Regards,
Kiran

hi,
there no rare rule whe you define your data type, why i tell you this, because you define a data type since the documentation that sender sistem team gives to you. so you only have to copy this structure to PI.
now about Message Type less problems, because, you a Data type is assign to a Message Type, whats it means.
when you define a DATA type you are defining the structure of you XML, que you assing the data type to a message type this structure pass to be an xml document.
Thanks you

Please help me .....

See:
http://struts.apache.org/struts-action/userGuide/building_view.html
The easiest thing to do is to store your application .properties files in your application's classes folder (WEB-INF/classes). Then in your struts-config file you just add:

<message-resources parameter="ApplicationResources"/>
Assuming you have ApplicationResources.properties, ApplicationResources_xx.properties. Make sure you put this tag in the relevant place for your struts-config DTD.
You also need to make sure you have an XML parser available (and not too many), so basically check you have an Xerces jar in your classpath somewhere. With tomcat this means putting the jar in the relevant directory (i.e. WEB-INF/lib)

I ran your file through an XML parser and the only error was on the line:<set-property property="password" value=null />because there are no quotes around "null". Fix that and try again. If you're using an IDE, there should be an option to validate the XML file which enables you to check struts.config before starting up the app.

Units field XYZ for field ABC of DataSource ZRST Message no. R8147

HI,
When I'm trying to SAVE my datasource ZRST, I've got following error.
Units field XYZ for field ABC of DataSource ZRST Message no. R8147
In extraction structure of this datasource thare are at least two fields that use the same unit field.
Accordign SAP note no 867795:
One of the fields is displayed and another is hidden.
Then the unit field is hidden and the above error occurs.
This note is valid for component SAP_ABA release 700. I'm running my R/3 source system on SAP_ABA 620.
Could it be the same case as described in this SAP note?
Anybody got same problem? Please advise.
Thanks
m./

Hi,
Please check the dependencies on the fields, as some fields should have the units defined ,check the fields and activate the datasource.
hope this helps,
thanks,
vrrp.

Error message "resource does not exist"

C6; have unistalled and reinstalled ovi store three times; now I get into the store, but when attempting to download app, get error message "resource does not exist". what is that???

hey guys just updating you all.. i wrote previously how my ovi store wasn't working, it gave me an error message 'resource does not exist'. i did soft/hard reset, also uninstalled ovi store and reinstalled STILL it wasn't working. It lasted a day. And today it's working fine. i think it was a problem with their server. It sorted it self out
But guys i did contact the team, and i got a reply that said i should do the following if it still doesn't work:
1. GO TO MENU
2. GO TO INTERNET
3. CLICK ON WEB
4.GO TO OPTIONS
5. GO TO CLEAR PRIVACY DATA
6. DELETE CATCHE AND COOKIES
That should apperantly work.
If not guys, then i wouldn't worry. Just like mines, yours should sort it self out
