Hello,
I'm currently trying to upgrade my company's application from JBoss 4.2 to JBoss 7.1.1.Final. I have gotten most areas to work except for a section of code that is using <jsp:useBean>. The error that i'm getting is:

2013-03-27 14:00:22: ERROR ApplicationDispatcher->invoke: Servlet.service() for servlet jsp threw exception
org.apache.jasper.JasperException: Unable to compile class for JSP:

My bean is located in the package "orderreportgateway.beans". My jsp is located in the root web folder. My file structure is as follows:

JSP:
Project.war -> ChooseReport.jsp

Bean:
Project.war -> WEB-INF -> classes -> orderreportgateway -> beans -> ReportListBean.class

I have all ready tried changing class="" to type="". I have also made sure that my bean has a default constructor that doesn't have any input parameters. My bean is not in the default package either. I don't understand why it is telling my that my first package name can't be resolved to a type. I don't think that it should be trying to validate it as a type since it is a package. When I redeploy this exact same code in JBoss 4.2, it works perfectly.

I guess another thing i should mention is that my JBoss 4.2 server is justing Java 5 and my JBoss 7.1.1.Final server is using Java 6. The JBoss 4.2 server is running on both Windows 7 (my development instance) and Unix. My JBoss 7.1.1.Final server is only running on Windows 7 (my development instance) until I get the last few problems solved. Then it will be moved to Unix.

My JSP is as follows (ChooseReport.jsp)

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<jsp:useBean id="reportList" scope="request" class="orderreportgateway.beans.ReportListBean" />
<html>
    <head>
        <link rel="stylesheet" type="text/css" href="/images/newEclipse.css">
        <title>Choose Report</title>
    </head>
    <body>
        <c:import url="/NewHeader.jsp" context="/common"/>
        <h1 align="center">Order Report Gateway</h1>
        <form name="chooseReport" action="OrderReportGateway" method="post">
            <input type="hidden" name="action" value="chooseReportOptions">
            <table class="interface" align="center">
                <tr>
                    <td>Choose Report Type:</td>
                    <td>
                        <select name="report" size="5">
                            <c:forEach var="report" items="${reportList.list}">
                                <option value="<c:out value="${report}"/>"><c:out value="${report}"/></option>
                            </c:forEach>
                        </select>
                        <input class="modifiedButton" type="submit" name="goToGateway" value="Continue..">
                    </td>
                </tr>
            </table>
        </form>
    </body>
</html>

My bean is as follows (ReportListBean.java)

package orderreportgateway.beans;

import java.util.*;
import database.DBAccess;
import database.wrapper.PasswdRptTable;
import database.Table;
import java.util.logging.Logger;

public class ReportListBean {

private static String EMPTY = "";
    private DBAccess db = null;
    private PasswdRptTable table=null;
    private String userLogonSeq;
    private ArrayList list = null;

public ReportListBean() { }

public void setDb(DBAccess db) { this.db=db; }

public void setUserLogonSeq(String userLogin) { this.userLogonSeq=userLogin; }

public void generateList()
    {
        try 
        {
            list = new ArrayList();
            table = new PasswdRptTable(db, Logger.getLogger(ReportListBean.class.getName()));
            //get list from db
            table.setCondition(table.GATEWAY, Table.EQUAL, "OrderReportGateway");
            table.setConditionFunction(table.LOGON_SEQ, Table.EQUAL, userLogonSeq);
            table.setOrderBy(table.REPORT_NAME);
            table.select();

int numItems = table.getRowCount();
            String record = null;
            if (numItems>0)
            {
                for (int i=0; i<numItems; i++)
                {
                  record = table.getString(i, table.REPORT_NAME);
                  list.add(record);
                }
            }
        }
        catch(Exception e){}
    }

public Collection getList() { return list; }
}

Any help would be greatly appreciated.

I still haven't solved this problem. I have gone over every piece of code with a fine toothed comb checking it. All of the spelling is correct and all of my folder structures are correct. I even checked to make sure I didn't have any leading or trailing white space on any of the names or folders. Any help would be greatly appreciated.

By any chance do you have a class named orderreportgateway (with some different case) in that application?

I do. In the default package there is a servlet with the name OrderReportGateway.java. It is the main entry point into the application.

I suggest moving this servlet from the default package to some other custom package which you should create beforehand.

That did the trick. I moved OrderReportGateway.java into a new package called orderreportgateway and everything started working again. I didn't even think about doing this because I thought java was case sensative. When it kept telling me that orderreportgateway could not be resolved as a type, I kept looking at the package name and not an unrelated class. Thank you for your help. This problem has been consuming me for a few days now.

Actually, it's a known bug involving Windows OS:

We should throw him a surprise party. It will cheer him up. We can use this tiny ad:
