## Reporting a problem or requesting a feature

If you are having trouble running JReport Designer or encounter any problems during reporting, take the following steps to troubleshoot it yourself first:

1. Check whether the system on which JReport Designer is running meets the system requirements.
2. Check the configuration of your JDBC drivers. JReport Designer supports database connections via various JDBC drivers and ODBC data sources via Sun's JDBC-ODBC bridge.

   Note: You need to install the JDBC or ODBC driver before installing JReport Designer. For more information about how to install the driver please refer to the appropriate JDBC or ODBC manuals.

   For more information, see Setting up the JDBC driver.

3. Check the FAQ in the Customer Care Portal for frequently-asked questions and their solutions.

If the problem persists, report it to Jinfonet Support (support@jinfonet.com) with the following information:

1. Describe the precise steps leading to the problem.
2. Run the batch file called jrenv.bat in the `<install_root>\bin` folder, which will generate a file called report.env in the current directory. Send this file to us.
3. Send us the catalog file (*.cat and*.fml) and the report file *.cls that you are having problem with.
4. Start JReport Designer with the batch file DJReport.bat. Running this batch file will generate the log file in the `<install_root>\logs` directory. Try to reproduce the problem, and send this log file to us.
5. In order to resolve the technical issues that you have reported, we need to access your report data so that we can recreate and analyze the problem. Regardless of the size of your database, we only require access to the data returned by the query of the particular report. We will execute a confidentiality agreement with you if necessary.

   To extract the report data, in the Catalog Browser, right-click on the data object that your report is using, select Create Cached Query Result. Input the data file name and click the Save button. The query result will be saved in the file. Send us all the files <file name>.* (including the description file also). If the main report contains subreport(s), repeat this also for each subreport.
