[jboss-user] Strange Problem with JBoss 4.0.1

Hi, Actually, I m facing a strange problem with JBoss 4.0.1. I m running JBoss 4.0.1 with Eclipse 3.2 and J2SDK 1.4. When I run my application on the JBoss 4.0.1 server, some times I get "NullPointerException" and some time it says "the requested resource ( myaction.do) is not found / unavailable". And then, if I refresh (immediately) the same page, it shows up the entire page. This happens 70% of the times. Another thing that happens is, some times images are not shown on the page, however when I refresh the same page, the page shows up perfectly (i.e along with the images). I m deploying the application properly. I first start the server using Eclipse. Once the Eclipse is up n running I deploy the application on the server (Run on server - option by right clicking on the project). On deploying application eclipse 3.2 opens the browser on its own with the welcome page. But, as I told u 70% of the times it gives me that problem. On the if I refresh the page it comes up properly. I feel that this is a problem with some JBoss setting, because if it is a problem with my application it would not run properly on refreshing the page. Apart from this my application is running properly on Tomcat 4.3 (with Eclipse 3.0). If u know any thing about this problem, please help me, if u can. Its urgent. Regards, Udayvir Singh
