UseBean Error
Hi,
I am developing a online price comparison tool in NetBeans 5.0 with Java 1.4.2_11and I am getting a few errors which I don't get when I run exactly the same code in JDeveloper 10.1.2.1.0. When I try to run the
index.jsp page I get the following error:
Created dir: C:\Documents and Settings\Colin\Desktop\PriceFinder\PriceFinder-war\build\generated\src
org.apache.jasper.JasperException: The value for the useBean class attribute List.CartBean is invalid.
C:/Documents and Settings/Colin/Desktop/PriceFinder/PriceFinder-war/build/web/index.jsp(28,4)
C:\Documents and Settings\Colin\Desktop\PriceFinder\PriceFinder-war\nbproject\build-impl.xml:342: Java returned: 1
BUILD FAILED (total time: 1 second)
This is the line that it fails on in the index.jsp page:
<jsp:useBean id="list" class="List.CartBean" scope="session"/>
This is the line that it fails on in the build-impl.xml file:
<java failonerror="true" fork="true" classname="org.netbeans.modules.web.project.ant.JspCSingle">
Also when I run the project as a whole I get this error but I guess that this is down to the previous error:
run-display-browser:
Browsing: ${client.url}
C:\Documents and Settings\Colin\Desktop\PriceFinder\nbproject\build-impl.xml:225: java.net.MalformedURLException: no protocol: ${client.url}
BUILD FAILED (total time: 4 seconds)
This is the line that it fails on in the build-impl.xml file
<nbbrowse url="${client.url}"/>
This is my CartBean:
package List;
import javax.ejb.*;
import java.util.Vector;

}
}
return intCounter;
}
publicvoid reduceQty(Integer itemID){
if(getQty(itemID)==1){
try{

}
catch (Exception ex){
System.out.println(ex.getMessage());
}
}

}
else{

}
}
publicint getItemCountRemain(){

return max;
}
else{

}
}
Any help would be most grateful. Thank you.>
