What is the executable file for the DataCollectionSoftware?

The JAR file,

DataCollectionSoftware-7.x.jar

is the executable file for the application. You shouldn't unpack it. It's ment to be executed directly.

More technically, JAR file is not an executable (i.e. exe) file for Windows. The real executable that is run in Windows, is the "javaw.exe" file, which shoud have the parameter "-jar" and the DataCollectionSoftware-7.x.jar file. The "javaw" program starts the JavaVirtualMachine, which executes the Java binary code that is inside the JAR file. The command-line startup should look like this:

javaw -jar DataCollectionSoftware-7.x.y.jar

When the JAR files are associated properly and you double-click it, the above command is being executed automatically (and silently - you don't see it).

I unzip the "DataCollectionSoftware-7.x.jar" file and there's nothing inside that I can run

You shouldn't unzip the JAR file, which is intended to be executed with Java^tm^. If JAR file has a ZIP icon, it's because your system mistakenly associated JAR file with a program like Winzip, instead of Java^tm^ JRE.

In such case, we recommend reinstalling the JRE (Java Runtime Environment), to let it associate the JAR file type with itself. The Sun writes:

On Microsoft Windows systems, the Java 2 Runtime Environment's installation program will register a default association for Jar files so that double-clicking a Jar file on the desktop will automatically run it with javaw -jar. Dependent extensions bundled with the application will also be loaded automatically. This feature makes the end-user runtime environment easier to use on Microsoft Windows systems. (from: JAR Guide)

I get “Unable to launch the specified application”

“Unable to launch the specified apllication” and in the details it says:

“An error occurred while launching/running the application.
Category: Invalid Argument Error
Could not load file/URL specified: C:\DOCUME~1\UTILIZ~2\DEFINI~1\Temp\javaws5”

You need to associate the JAR files differently. JAR files should be associated with

javaw -jar

Why is in the diagnosis/procedures list the possibility X not available any more?

The new software contains updated short-list. The procedure/diagnosis was probably excluded from short-list. Current procedures and diagnoses short-list follows the document:

EACTS-STS Diagnosis and Procedure Short Lists 2004-10-24.xls

You can download the PDF version of this file: EACTS-STS Diagnosis and Procedure Short Lists 2004-10-24.pdf

When and how can the completed files be sent to the CentralDatabase?

The next release of software will contain the data export function. When it's implemented, you will be able to export the data on demand. See also DataCollectionSoftware/DataExport.

What is the primary key for the Patient table?

The primary key consists of two fields: the hospital code and automatically generated integer number.

The graphical user interface of the Data Collection Software does not show the primary key anywhere. If you want to export the data from the Data Collection Software to other relational database, the primary key will get exported as well. The patient table looks like this:

Hospital Code	Number	First Name	Last Name	Other fields...
ABC	1	John	Doe	...
ABC	2	Ann Mary	Smith	...

For information about the primary key in CSV export files, please read about the data export.

Please note that the primary key is something different from the local ID.

What is the Patient's Local ID?

Patient local ID technically is a plain text field. It can be used by the hospital according to the center's needs. This field is exported to the central database and can be used to track exported patients.

How to configure the user and password for the database in the NetworkInstallation?

The user name and password are defined in the dburl variable in the ecdbc.properties file. Please consult the network installation for details.

Why the network version of software works slow?

There can be many reasons for it. One of them is the lack of configuration of the revDNS. While operating in the local networks, computers try to resolve IP numbers, e.g. 192.168.0.4 to a DNS canonical name (like somehost.localnet). When the revDNS is not configured to resolve IP numbers to canonical names, the computer waits about 30 seconds for the IP number to be resolved, and this is perceived as application slowness.

There is no unique identifier in each CSV/Excel file, i.e. "Primary Key"

For information about the primary key in CSV export files, please read about the data export.
