Help with running reports

2004-07-02 00:30

I am new in using Jasperreports and I tried compiling on demo application, particularly QueryApp.java. The compilation is successful but when i try to run the program, it doesnt produce the report itself. Currenly I am using MySQL as my database. In the java file, I tried to change the parameters, database connection, and the .jasper file but still it wont work. I need help please ASAP. Thanks. I have a deadline in making the reports and its two days from now. If possible, i would appreciate it more if someone can give me a working application that can display a certain report in MySQL database. Thank you

What's the error output in console?

 

I don't use MySQL but be sure to have the connection established successfully. I guess you will have to copy the needed JAR-libs for MySQL-driver into the lib-directory of jasper-reports (so I had to do, with MS-SQL-Server JAR's)

 

If you use the same tables in your MySQL-Table it sould work. (I canged the HSQLDB-Sample towards MS-SQL-Server, and it worked)

After setting up all the needed jar files, and making a replica of the database written in HSQLDB to MySQL, the java files in the demo folder would run already? How? By issuing the java command in the console?

Well actually you just have to replace the "getConnection" method in the query-sample (for example) to the MySQL specific lines.

 

private static Connection getConnection() throws ClassNotFoundException, SQLException

{

//Change these settings from HSQLDB according to your local configuration for example to MySQL

String driver = "org.hsqldb.jdbcDriver"; //Don't know how the MySQL-Driverstring should be, but I guess you know it.

String connectString = "jdbc:hsqldb:hsql://localhost";

String user = "sa";

String password = "";

 

 

Class.forName(driver);

Connection conn = DriverManager.getConnection(connectString, user, password);

return conn;

}

 

that should be enough. You have to recompile the java-file and than start the ant-tasks "compile" then "fill" and then "view"... that must work if you have the same table with the same fieldnames/types in your MySQL-Database! If not, than your "getConnectionMethod" should throw an exception.

it compiles without errors but it produces the output:

here's my code:

What's wrong with my code? Please help me...

Well you have to install ANT and put it into your PATH to call it anywhere from commandline... then go to your directory from the modified sample and look for the "build.xml"... there are so called "targets" within.... (each target makes a different job)

 

make a new commandline from that dir and put

ant compile

 

the files should get recompiled....

 

then

 

ant fill

 

and the report XMLfile should get filled to a jrprint-file

 

then

 

ant view

 

and the JRViewer should appear...
