Hi

the below SOP is returning "." in an AIX machine , whereas I'm expecting the absolute path any Idea how/from where JVM fetches this value in a AIX machine.


public class aaa{
public static void main(String args[]){
System.out.println(System.getProperty("user.dir"));
}
}

Hi All,

Wanted to know the below clarifications w.r.t Sun JVM and IBM JVM interaction

1) Can Sun JVM connect to IBM JVM (specifically WAS) without having the ibm specific libraries(jars) in the classpath ?
2) Queries written to fetch Managed Server objects on IBM Websphere Application Server,how exactly the flow is carried out to fetch those Managed Beans object ?

In above code snippet the "isMulticasAddress()" method is returning true for the Address 225.0.0 , actually it should return false as per our understanding ,it would be great if anyone of you let me know whether this is a correct behavior or not.

Thanks for the response Kurtcebe and Deepak.

The total size of WEB-INF is 33MB, of which lib contributes about 20 MB,Shared Library is already created and referenced.what is the minimum set of Files I need to provide at the time of deployment AFAIK web.xml and WEB-INF/lib and WEB-INF/classes referenced inside web.xml are mandatorily required at the time of Deployment, Rest of the Files I will copy to respective directories post Deployment of war Please let me know if there is any problem adopting this approach.

I have converted a WAR to EAR for shared lib references(which is one more EAR), the jars which were present in WEB-INF/lib of WAR were moved to .ear/lib folder to make the newly created EAR Applications work, is this required as part of WAR to EAR conversion or are we missing some configuration here.

We have two web applications each of size 111MB as of now it is taking a minimum of 30 mins for each war to get deployed in WAS, we want to redeuce the time taken for deployment and are looking for different ways we can handle this scenario. Please share your inputs regarding this.

Hi Bear Bibeault ,

Thanks for the clarifications was not aware of the thing called InvokerServlet.

I need couple of more inputs w.r.t this.

1) Is this InvokerServlet part of Servlet 2.3\2.4 Specification
2) Is it something specific to Tomcat (The servlets are getting invoked in Websphere also.).
3) Where exactly is this InvokerServlet mapping is done (any standard xml file read by Web Containers).

I'm seeing couple of Servlets getting called without a Servlet mapping element being present in Deployment Descriptor.

The url being hit is http://mydomain.com/Approot/Servlet/com.mycompay.mypackage.ServletClassName.

Can anyone explain me how is this possible ?

we recently upgraded our oracle 10g from 10.2.0.1 to 10.2.0.4 after that the following Java code is throwing an exception

stmt = conn.createStatement();

Any inputs regarding this would be of great help.
folks sorry for the late reply here are the findings.

There are four App Server Nodes(WAS Cluster Setup) on which my application is deployed out of four Nodes, 3 Nodes are taking 45 seconds where as one node is taking 8 seconds

On further Analysis we found its the DB Queries(All are read only queries) which are taking around 40 seconds in these 3 Nodes.

All the four Nodes are synchronized with a deployment Manager. All configurations such as specifying db url ,JVM args are done at the deployment manager level only.

Now what we need to find is why the 3 Nodes are taking 40 seconds to run the Database Queries.

Please let me know if you need further inputs.

And are either of those operations liable to be slow?
Not really Development setup is takes around 3-4 seconds Production it also it is taking the same time(it has to go thru a LB and an IHS in production)

What does the authentication step involve?
this involves an interaction witn another web application which is deployed on the same Appserver.

What data do you pull back to put on the home page (if any)?
basically an applet containing some menus no retrieval of heavy data from database.

My point is in my IE watch data it says /MyServlet -45 seconds to respond with httpresponse
Inside my servlet the processing time i calculate is roughly around 4-5 seconds(in production Environment)
Where is the rest 40 seconds spent ?
