Hi,
I am able to perform JNDI lookup using the following code in any of my servlet as follows,
DataSource ds = null;
Context ctx = null;
try {
String strDSName = "java:jboss/datasources/Test";
ctx = new InitialContext();
ds = (javax.sql.DataSource) ctx.lookup(strDSName);
} catch (Exception e) {
}
*But the same code fails if it is invoked from init() method of load-on-startup servlet.* My datasource is bound well before this.My console says,
13:26:06,881 INFO [org.jboss.as.connector.subsystems.datasources] (MSC service thread 1-2) Bound data source [java:jboss/datasources/weblogic.jdbc.jts.demopool]
*web.xml entry*
---------------------
<servlet>
<servlet-name>StartupServlet</servlet-name>
<servlet-class>com.metreo.common.web.servlet.StartupServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
*servlet code*
-----------------
public class StartupServlet extends HttpServlet
{
/**
* init method
*/
public void init(ServletConfig a_config)
throws ServletException
{
super.init(a_config);
System.out.println("StartupServlet.init() called.");
try {
InitialContext ctx = new InitialContext();
DataSource ds = (javax.sql.DataSource) ctx.lookup("java:jboss/datasources/weblogic.jdbc.jts.demopool");
System.out.println("context info in StratupServlet init method...."+ds);
callStartupClasses();
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
Please help me resolving this issue. I am stuck with this for a long time.
Thanks,
Abiya

Sorry for the late response on this question :(
The jBPM console overlays divs ontop of the image in order to display the red arrow icon next to active nodes in your process. Here is some sample code that does this:
String s =
"<div style='width:1024px; height:768px; background-color:#ffffff;'>" +
"<div id=\"imageContainer\" style=\"position:relative;top:-1;left:-1;\">" +
"<img src=\""+imageUrl+"\" style=\"position:absolute;top:0;left:0\" />";
for (ActiveNodeInfo activeNodeInfo: activeNodeInfos) {
s+= "<div class=\"bpm-graphView-activityImage\" style=\"position:absolute;top:"+ (activeNodeInfo.getActiveNode().getY()-8) +"px;left:"+(activeNodeInfo.getActiveNode().getX()-8)+"px;width:50px;height:50px; z-index:1000;background-image: url(images/icons/play_red_big.png);background-repeat:no-repeat;\"></div>";
}
s+= "</div>" +
"</div>";
Hope this helps.

Hi,
I modified jboss-classloading.xml as follows:
+ <?xml version="1.0" encoding="UTF-8"?>+
+ <!--See http://phytodata.wordpress.com/2010/10/21/demystifying-the-jboss5-jboss-c... http://phytodata.wordpress.com/2010/10/21/demystifying-the-jboss5-jboss-c...>+
+ <classloading xmlns="urn:jboss:classloading:1.0"+
+ name="test.war" +
+ domain="test"+
+ parent-first="false"+
+ export-all="NON_EMPTY"+
+ import-all="true">+
+ </classloading>+
*It helped to solve above mentioned excpetion.And because of this configuration I got rid of the Original Exception also which has been posted in very first post.*
* Thanks for all..*
But because of this configuration I got another deployment Exception.I am posting this stack trace too.

I observed that *%JBOSS_HOME% \common\lib\hibernate-entitymanager.jar* is getting conflicting with *WEB-INF\lib\hibernate-entitymanager-3.6.3.Final.jar*
But how is this possible eventhough I have set *+domain="test"+* .
Is My observation Correct ?
Please correct me If I am doing mistake .
