The Abstract of Assessment (abstract) is a compilation of all real and personal property located within the boundaries of each county. Under 39-5-123, C.R.S., each county assessor is required to file this report with the Property Tax Administrator annually. Real and personal property is classified according to use and listed accordingly within ten property classes. The ten property classes, as established by the Administrator, are: vacant land, residential, commercial, industrial, agricultural, natural resources, producing mines, oil and gas, state assessed, and exempt property. Within each property class, various subclasses are designated. Each subclass is assigned a four-digit code for identification purposes. Please see the Subclass Codes for more information.

The application is hosted on a server housed at the Colorado Department of Local Affairs. It uses Java servlets to display forms and reports in your Web browser. So, you will need the Java Runtime Engine (JRE) installed on your computer. If you do not have it or have a version prior to 1.5, you can download it. If you are not sure what version of the Java Runtime Engine you have installed, you can find out here. Please note that we no longer support Oracle's version of the Java Runtime Engine, Jinitiator.
You will also need the Acrobat Reader installed on your computer to view and print the Certification of Levies reports. Version 4.x and above will work, although we recommend version 9.x or greater. If you do not have the Reader, you can get a free copy at http://www.adobe.com/.
The Certification of Levies application should work with any browser that supports the Java Plugin. The table below shows the operating systems, browsers and Java versions that are certified by Oracle to work with Forms 10gR2. The table was excerpted from Oracle's client statement of direction, which was revised on 1 March 2010.
1. Sun's JRE has not been certified with Windows 2003 and is therefore not supported, but appears to work.
2. Running on Windows.
3. Webutil is currently certified only on Mac clients with Safari 2.0.3 and Sun's plug-in 1.5.0_06.
Internet Explorer version 7 has been certified on XP only.
4. Vista and Windows 7 users should consider using Sun's plug-in 1.5 or 1.6 as shown in the matrix.
5. Sun's plug-in 1.6 was certified with Internet Explorer 7 and Firefox 2.0 only.
6. Linux flavors supported: Red Hat RHEL 3, 4, and 5; Novell SLES; Oracle EL 4 and 5, and Asianux. Other flavors may work but have not been tested.
7. The version listed is the version which was certified (tested). Newer production versions of the same major release number will be supported although they may not have been tested.
8. Though not tested by Oracle, local testing of Firefox 3.x running on Windows XP show that it appears to work. However, Firefox 3.6 requires the use of Java Plugin version 1.6.0_10 or above due to changes in the programming interfaces supported in the browser.
9. Some functions may work differently on Mac clients and others may cause Java exceptions. Oracle documents at least three such issues on their support web site.
The first time you run the application, the server must transfer some components of the application to your computer. These components (Java Archive (JAR) files) can be up to 2.4MB (2.5 million bytes) in size. Over a dial-up connection, it will take seven to ten minutes to complete the transfer. Once this one-time transfer is complete, the application should display the Main Menu form.
Subsequent use of the application does not require this file transfer, so the Main Menu form should load in less than 15 seconds. If startup is still slow, the network or our server may be busy. You may want to try again a bit later.
You may also want to try clearing the Java cache. Please see General Troubleshooting below for instructions.
This can happen in either of two situations. The first time you run the application, you are likely to see a security dialog box indicating that "The application's digital signature has been verified. Do you want to run the application?". This dialog indicates that your browser was able to validate the Java Archive (JAR) files and determined that it was created by Oracle and that the digital signature was valid. Please click the box that says "Always trust content from this publisher" and you won't be bothered with it again unless you clear the JAR cache.
You may also see a similar dialog that says "The application's digital signature cannot be verified. Do you want to run the application?". When this happens, it usually because the digital certificate used to sign the Java Archive (JAR) file has expired. Once again, please click the box that says "Always trust content from this publisher" and you won't be bothered with it again unless you clear the JAR cache.
The other situation that may arise is a dialog box that says "Java has discovered application components that could indicate a security concern." We use Java archives (a.k.a. JARs) to hold the icons associated with our applications. These JAR files are not signed with security certificates (more about this below.) Version 1.6.0_20 and above of the Java plug-in sees these icon JAR files as unsafe components, even though they contain only tiny pictures (GIF files). If you click the "No" button on this dialog, the icons will display as expected, but if you click the "Yes" button, the icons will be missing. The application will work either way.
Unfortunately, there doesn't seem to be a way to set this permanently, so it will pop up each time you run the application. We are investigating ways to sign the icon JAR files to stop this from happening and we expect resolution very soon.
This is normally due to one of two causes. First, if your browser has a pop-up blocker running, it may prevent the reports from being displayed, since they open in a separate window. You may either disable the pop-up blocker entirely or add our site as an exception. If you wish to exempt our site, please add "dola.colorado.gov", "state.co.us" and "colorado.gov" to your list of exceptions. Please consult the documentation for your browser or stand-alone pop-up blocker for more information.
Second, you may not have the Acrobat Reader installed on your computer, so the reports are not viewable. Please see the "How do I use the application" section in this document for more information.
The application starts to load but stops with an error "FRM-92050 - Failed to connect to the server...". This error can occur due to problems at the server or on the computer running the browser session. If you are using Internet Explorer version 6, your browser settings, particularly related to cookies and Java, can cause this error. To run the application, you will need to permit session cookies from our site. You should also have your Java permissions set to allow both signed and unsigned content. Please see the General Troubleshooting section below for details on these settings.
If you are sure that your browser settings are correct, the problem is likely to be on our server. Please press the 'Details' button in the error dialog window to bring up the Java error stack. Take a screen print shot of this stack for future reference; it really helps technical support to have this information.
The application starts to load buts stops with an error "FRM-92060: Failed to connect to the server." This error occurs if a proxy or firewall between the application server and your computer prevents the transfer of the JAR files. If you are required to use a proxy for Internet access, please check with your network administrator to see if the appropriate port is allowed through.
This can also be an issue with personal firewalls (installed on your computer) or network firewalls maintained by your network staff. All of the network traffic is on port 443, the secure HTTP port, and port 80, the standard HTTP port.
The application is running but stops with an error "FRM-92100 - Your connection to the server was interrupted. It is necessary to reestablish the session.". This error occurs when the connection between your computer and our server breaks down. Due to the way we have configured our server, this error (and the related FRM-92102 error) should very rarely happen. If it does, it is likely to be due to transient network problems somewhere along the line. Because the errors are transient, it is likely that closing your browser (both windows) and restarting it will let you work again.
Java sometimes has trouble correctly interpreting the proxy settings used by the browser. If you suspect this may be the case, please verify the settings in the Java control panel. On the "General" tab of the control panel, click the "Network Settings" button to see the proxy settings. Normally, the default setting of "Use browser settings" works well. However, if necessary, you can manually enter the appropriate proxy settings provided by your IT staff.
The application is running but stops with an error "FRM-92102 - A network error has occurred...". This error is due to intermittent failures of the connection between your computer and our server. Due to the way we have configured our server, this error (and the similar FRM-92100 error) should very rarely happen.
It can happen if the Java proxy settings on your computer are incorrect. If you suspect this may be the case, please verify the settings in the Java control panel. On the "General" tab of the control panel, click the "Network Settings" button to see the proxy settings. Normally, the default setting of "Use browser settings" works well. However, if necessary, you can manually enter the appropriate proxy settings provided by your IT staff.
In many cases, this will take care of the problem. However, it can also happen when our server or the network between your computer and our server becomes overloaded. If you think this may be the case, please close your browser and try again later.
The application cannot run in Internet Explorer 7 when there are add-ons that use conflicting versions of Java. To solve this problem, you will need to:
