Problem while incrementing a variable in Jasper Reports

Hi
I am using Jasper Reports for designing reports. These reports will be used by my Java application.
But there is problem while I am trying to increment a variable depending on some condition.
Requirement: I have to display information about all the residents in a hospital in a single report. Resident information will be fetched from the XML file. When a resident ID is found in the XML, then the variable(resno) shoud be incremented. I have set the initial value to 1.
Problem: Only for the first resident, resno is showing as 1. For all the remaining residents, its showing as 0 (zero).The variable 'resno' is not incrementing for each resident.
Even the ResidentID is not null. All the ResidentID's exists in the XML file.
Please find the code below.
<variable name="resno" class="java.lang.Integer" incrementType="Group" incrementGroup="residentbrk" calculation="Count">
<initialValueExpression><![CDATA[new Integer(1)]]></initialValueExpression>
</variable>
<group name="residentbrk" isStartNewPage="true">
<groupExpression><![CDATA[$F{ResidentID}]]></groupExpression>
<groupHeader>
<band height="16">
<textField hyperlinkType="None">
<reportElement positionType="Float" x="0" y="-1" width="96" height="17"/>
<textElement>
<font isBold="true"/>
</textElement>
<textFieldExpression class="java.lang.String"><![CDATA[$R{residentno}]]></textFieldExpression>
</textField>
<textField hyperlinkType="None">
<reportElement positionType="Float" x="96" y="-2" width="64" height="18"/>
<textElement/>
<textFieldExpression class="java.lang.Integer"><![CDATA[$V{resno}]]></textFieldExpression>
</textField>
</band>
</groupHeader>
</group>
Could you please provide a solution for this.

Not clear at all. May be like this
declare
v_temp varchar2(100);
v_final number;
begin
--loop
v_temp:='sun';
v_temp:=translate(lower(v_temp), '1abcdefghijklmnopqrstuvwxyz', '1');
dbms_output.put_line('Temp:'||v_temp);
v_temp := v_temp || 'Mon5.1';
v_temp:=translate(lower(v_temp), '1abcdefghijklmnopqrstuvwxyz', '1');
dbms_output.put_line('Temp:'||v_temp);
v_temp:= v_temp || 'Tue';
v_temp:=translate(lower(v_temp), '1abcdefghijklmnopqrstuvwxyz', '1');
dbms_output.put_line('Temp:'||v_temp);
v_final:=to_number(v_temp);
dbms_output.put_line('v_final'||v_final);
--coalesce
--end loop;
end;

Problem in debuging jasper reports and ADF

Hi
I am using JDeveloper 11.1.2.2.0. Inside I created Fusion Web Application ADF, and on the index page created Go button. Now I created Servlet with doGet methode and conncected it to Go button. It is working OK.
Now I want to run simple jasper report from servlet. Jasper report is based on empty dataset. Here is servlet code:
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
ServletOutputStream servletOutputStream =response.getOutputStream();
InputStream reportStream = getServletConfig().getServletContext()
.getResourceAsStream("C:/Users/myDomain/Desktop/Reporting/ReportPDFPrazan.jasper");
try
JasperRunManager.runReportToPdfStream(reportStream,servletOutputStream,null, new JREmptyDataSource());
response.setContentType(CONTENT_TYPE);
servletOutputStream.flush();
servletOutputStream.close();
catch (JRException e)
// display stack trace in the browser
StringWriter stringWriter = new StringWriter();
PrintWriter printWriter = new PrintWriter(stringWriter);
e.printStackTrace(printWriter);
response.setContentType("text/plain");
response.getOutputStream().print(stringWriter.toString());
When I hit Go button here what I get:
java.lang.NullPointerException

I also imported this libraries inside ViewControl project:

     IText-2.1.7.jar
     Groovy-all-1.7.5.jar
     Poi-3.7-20101029.jar
Can someone help me with debuging. Please
Edited by: MarcusO on 2012.10.23 05:18

I found solution. It should be used like this:
InputStream reportStream = new FileInputStream(new File("C:/Users/myDomain/Desktop/Reporting/ReportPDFPrazan.jasper"));
So problem was in input stream. It works fine now.

Hi nanzee.
The problem u posted above looks similar to the one i'm facing now. I'm also getting a No ClassDefError when creating a jasper report on Linux. It works just fine on Windows 2k though.
I was hoping if u can share more specific details on how you managed to solve this problem. Your solution just might work for me.
Please shed more light on the ff:
1. "It has something to do with my missing fc3 linux libraries so i did an rpm for the deprecated libraries " -- how is this done? I'm not that versed in Linux. ( Our company requires us to use Linux ...)
2. "plus set something on my tomcat CATALINA_OPT portion "
Thank in advance and hope to hear from you nanzee.

Jasper Reports problem

Hi,
I have just begun to use Jasper Reports, and I am trying to load a sample JR xml file into a jsp in my web application.
report.jsp
<%@ page
   import="java.io.*,
           java.util.*,
           java.sql.Connection,
           javax.sql.DataSource,

           net.sf.jasperreports.engine.*,
           net.sf.jasperreports.engine.design.JasperDesign,
           net.sf.jasperreports.engine.xml.JRXmlLoader,
           net.sf.jasperreports.engine.export.*"
%><%@page import="com.energyts.ebench.*"
%><%@page import="com.energyts.db.*"
%><%@page import="java.sql.ResultSet"
%>
<%
     out.println("Attempting to create Jasper report");
     try{
     // read in xml design
     InputStream input = new FileInputStream(new File("c:\\Tomcat 5.5\\webapps\\eBench\\report.xml"));
     JasperDesign design = JRXmlLoader.load(input);
     // compile design
     JasperReport report = JasperCompileManager.compileReport(design);
     // Database connection
     Statement statement = EbenchUtils.getStatement(session);
     JasperPrint print
    = JasperFillManager.fillReport(report, new HashMap(), statement.getConnection());
       JasperExportManager.exportReportToPdfFile(
                 print, "reports/simple_report.pdf");
     }catch (JRException e){
          out.println("failed");
          e.printStackTrace();
%>I am using Tomcat 5.5 and JasperReports 2.04
I am getting this error:
HTTP Status 404 - reports\report.xml (The system cannot find the path specified)
type Status report
message reports\report.xml (The system cannot find the path specified)
description The requested resource (.\reports\report.xml (The system cannot find the path specified)) is not available.
Is the way I declare my path not declared correctly (the file is in the directory)? do the Tomcat settings need to be changed for this to work?
Any suggestions
Thanks
J

I learned that my mistake was that I am not using the .jasper file. I have a new error now although I already put the needed file inside the classes folder. This is the error:

Pyro Jasper Report Tag problem

Don't know if this is the right place to post this. I have an
app I'm currently working on that needs a reporting module
included. Found a tag on the Exchange
(<cf_Pyro_JasperReports>) makes use of the Jasper Report API.
Designed my reports with iReport, and all works fine on Adobe's CF
server, however due to cost this is being deployed on Railo's CF
server. The tag was specifically built for Adobe.
I made some changes in the tag which should be okay, but
Railo keeps throwing an error message "
can not load class through its string name, because no
definition for the class with the specifed name
[dori.jasper.engine.JasperManager] could be found" which means
all the necessary jar files (Jasper API) for generating the report
might not be in the right dir.
Tried all I can and still come up with the same error even
after placing the files where I feel they should be and restarting
the server. Has anyone worked with this tag or Railo before, please
would appreciate any assistance.
Thanks

I imagine you could place the necessary jar files in the
railo\lib directory if there are no conflicts. Though I would think
there is a central directory for external jars, like \WEB-INF\lib
or \ext-webapp. Try asking over at
http://tech.groups.yahoo.com/group/railo_talk/.
Let us know what you discover.
Good Luck

Open Jasper Report in new page using servlet

Guys,
Looks very simple but i am having problem making this process work. I am using 11.1.1.4
This is my use case:
- From a employee page, user clicks on a menu item to open report for current employee. I need to pass appropriate report parameters to servlet and open report into new page.
I can successfully call servlet using commandmenuitem and set request parameters and call servlet from backing bean.... but that doesn't open report in a new page.... any way i can do this?
Another option i tried was that using gomenuitem and setting target=blank but in that case i need to pass the parameter using servlet url which i like to avoid.(in case i need to pass many parameters in future) (also values will be set on page so i need to generate url when then click the menuitem...... so there are some hoops and loops i need to go through) I don't know a way to pass the request parameter using backing bean to servlet... i don't think it is possible.
Those are the two approaches i tried.
If you have any better approach...I would appreciate if you can let me know. (i have searched on internet for two days now.... for the solution)
