ArcIMS, Tomcat and IReport Issues

Team,

I got a task to create some new IReport Templates. IReports will compile the report template into .jasper files which can be called from a .jsp application. It’s all Java and open source.

 This IReport application was installed on a Windows 2003 Server running ArcIMS 9.2 Build 514.2165, Apache Tomcat 5.5 and JDK 1.5.0_15.  

The first problem I faced was, the reports were blank. In the preview it will work fine. But when the .jsp file calls the .jasper file, only the Header and Footer will show-up but not the detailed data section of the report. I posted the problem in this link.

http://jasperforge.org/plugins/espforum/view.php?group_id=102&forumid=103&topicid=84297

After researching many links I copied few selected .jar files of the IReport\modules\ext folder to the Tomcat\lib folder then I got this error.

http://jasperforge.org/plugins/espforum/view.php?group_id=102&forumid=103&topicid=84302

================================================================

ERROR: failed to generate report...
...Error: java.lang.ClassCastException: cannot assign instance of net.sf.jasperreports.engine.base.JRBaseRectangle to field net.sf.jasperreports.engine.base.JRBasePen.penContainer of type net.sf.jasperreports.engine.JRPenContainer in instance of net.sf.jasperreports.engine.base.JRBasePen

================================================================

Again did some more research and I found copying .jar files in the %JAVA_HOME%\jre\lib\ext folder might help? But it didn’t.

The biggest problem was to find the exact .jar files which is required by the IReport latest version 4.0. Whenever I copied the new version .jar files either ArcIMS will break or IReports will not work. IReports latest version 4.0 never worked for me.

Then finally I decided to rollback with an advice of a friend. There was an IReport 1.3.3 version installed on the same server. Once I rolled back to this old version then everything started to work fine.

In conclusion with the existing ArcIMS/Java and Tomcat combination IReport latest version 4.0 will not work.

If I find a workaround I will post back again.

Could not load type Pagebase

This error showed up when I uploaded my ASP.NET AJAX enabled website to my IIS Webhosting service provider. I was breaking my head and thinking what went wrong.

I published my application in a sub-folder inside the main root folder.

My main domain is www.advancedtechnologyworks.com

The new application I was trying to publish was inside a subfolder like www.advancedtechnologyworks.com\PrayerHelp\

I was checking the Web.Config file inside the sub-folder “PrayerHelp” and all was fine.

Then finally I discovered there was another “Web.Config” on the main domain which was causing this issue.

The Web.Config file was like this

<?xml version="1.0"?>

<!--

    Note: As an alternative to hand editing this file you can use the

    web admin tool to configure settings for your application. Use

    the Website->Asp.Net Configuration option in Visual Studio.

    A full list of settings and comments can be found in

    machine.config.comments usually located in

    \Windows\Microsoft.Net\Framework\v2.x\Config

-->

<configuration>

       <appSettings/>

       <connectionStrings>

       </connectionStrings>

       <system.web>

              <compilation debug="true" targetFramework="4.0">

              </compilation>

              <authentication mode="Windows"/>

              <pages pageBaseType="PageBase" controlRenderingCompatibilityVersion="3.5" clientIDMode="AutoID">

              </pages>

              <anonymousIdentification enabled="true"/>

              <customErrors mode="Off"/>

              <profile enabled="false">

                     <properties>

                           <!-- Available values for the StyleSheetTheme attribute: "Green", "Brown", "Red".-->

                           <add name="StylesheetTheme" defaultValue="Red" allowAnonymous="true"/>

                     </properties>

              </profile>

       </system.web>

</configuration>

I also identified this “PageBase.cs” file was inside the “App_Code” folder in the main domain folder.

I created the same “App_Code” folder inside the sub-folder “PrayerHelp” and copied this “PageBase.cs” file.  Eureka!  Everything started to work.

So when this error shows up, examine all the Web.Config files and see whether there is a reference to a new class file and make sure that class file is placed inside the App_Code folder.

Hope this tip helps someone.

ArcGIS Silverlight API Printing with Map to Scale

Printing in ArcGIS Silverlight API needs some special coding. To print Map to scale, I have introduced a duplicate Map Control and copying the layers to this control during Print operation.

Here is the working XAML code and the C Sharp code.
