Hi,

Can we connect multiple sources at one time from jasper Report ? Do we have to drag drop columns or write querries using DBlinks ? Please let me know.

Thanks,
Yati
Hi,

I have to use a web search for my project and I would like to ask you following questions:

1) Does Lucene saves the search of previous keywords somewhere(cache) ? Or it will be a new search everytime for same key words ?

2) If I search on some subset of key words in next search - will Lucene look into some cache results or it will be a new search ?


Thanks,
Yati

Hello All,

I am new to Spring and trying to understand ftl file basics and meaning of

?has_content

?default('')

?string("MM/dd/yyyy")

I could not find these tags anywhere. Can anyone please tell me where should I find these tags. they are included in the .ftl files and we have included

org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver

in our web-inf files.

Please help me in understanding the basics of these tags.

Thanks,
Nisha.

Hi,

I am facing this problem in my Sevlet code.

Context initContext = new InitialContext();
Context envContext = (Context)initContext.lookup("java:/comp/env");
DataSource ds = (DataSource)envContext.lookup("jdbc/hr");
Connection conn = ds.getConnection();


Cannot create PoolableConnectionFactory (No more data to read from socket)
I am using tOmcat 6.

When I write normal,
conn = DriverManager.getConnection("jdbc:oracle:thin:@127.0.0.1:1521", "hr", "hr");

Its working, but not the one with JNDI. Pls help..

Hi Saurabh,

I am still h aving problem in compiling my java files which are in one of the packages on Websphere. The problem is that "javac" compiler is not identifying the packages mentioned on the top of class which I have imported. I have included all Jar's files in the classpath - Could you tell me where I went wrong.


My import statement looks like :
import java.io.IOException;
import java.rmi.NoSuchObjectException;
import java.util.Vector;
import javax.ejb.CreateException;
import javax.ejb.FinderException;
import javax.servlet.ServletConfig;
import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import javax.servlet.http.HttpSession;
import com.ibm.websphere.samples.plantsbywebsphereejb.Catalog;
import com.ibm.websphere.samples.plantsbywebsphereejb.CatalogHome;
import com.ibm.websphere.samples.plantsbywebsphereejb.CustomerInfo;
import com.ibm.websphere.samples.plantsbywebsphereejb.OrderInfo;
import com.ibm.websphere.samples.plantsbywebsphereejb.OrderKey;
import com.ibm.websphere.samples.plantsbywebsphereejb.ShoppingCart;
import com.ibm.websphere.samples.plantsbywebsphereejb.ShoppingCartContents;
import com.ibm.websphere.samples.plantsbywebsphereejb.ShoppingCartHome;
import com.ibm.websphere.samples.plantsbywebsphereejb.StoreItem;
import com.ibm.websphere.samples.plantsbywebsphereejb.Util;

and After I am compiling my Java file, Iam getting problem as -

ShoppingServlet.java:238: cannot find symbol
symbol : variable Util
location: class com.ibm.websphere.samples.plantsbywebspherewar.ShoppingServlet
Util.debug("updatequantity: shopping cart ref must have timed out
, create a new one");

Where as I have imported the file Util through import statements.
