You actually don't need to install JInitiator (jinit 1.3.1.21) to run Oracle Applications on Firefox if you already installed the Sun JRE 1.4.2 and above. You will need to edit pluginreg.dat On Windows, that file is located at %APPDATA%\Mozilla\Firefox. Make a copy of the existing one first in case something goes wrong. Search for NPJava14.dll because Oracle runs on Java 1.4. This will appear whether you have installed Java 5 or 6. You will need to add the following line to at the end of the plugins. 6|application/x-jinit-applet;version=1.3.1.21|Java||$ Then update the count at the top of the section. Your modified pluginreg.dat will look like: C:\Program Files\Java\jre1.5.0_09\bin\NPJava14.dll|$ |$ 1160594743000|1|5|$ Java Plug-in 1.5.0_09 for Netscape Navigator (DLL Helper)|$ Java(TM) 2 Platform Standard Edition 5.0 Update 9|$ 7 0|application/x-java-applet;version=1.4.2|Java Applet||$ 1|application/x-java-bean;version=1.4.2|JavaBeans||$ 2|application/x-java-applet;version=1.4.1|J

The following are useful tips for non-Java people like me. Adding Groovy support to iReport should do the trick but it requires an additional library. The tricky part with iReport variables is getting the data types to match. The highlighting feature of Eclipse BIRT is much better than how it is being done in iReport/Jasperreports. I usually use an arrow character than changing the background color as it looks cleaner in the report design. Accessing variables, parameters and fields $P{fieldName} - is for parameter $F{fieldName} - is for fields $V{variableName} - is for variables To highlight a row when it reaches a certain condition: 1. Add a text field 2. In the properties under PrintWhenExpression: new Boolean($F{owner}.equals("username")) The key thing here is that if the field owner is true, it will print the text field. To set a default date: new SimpleDateFormat("yyyyMMdd").parse("20050101") To show overall statistics on the first page of the r

If your Eclipse BIRT report suddenly runs with errors after upgrading to BIRT 2.1.1, check if your SQL statement contains any division expression (i.e. SELECT month, sales / 12 FROM table1). This is a bug in 2.1.1 which was corrected in 2.2. Unfortunately, 2.2 is still a milestone release (not stable). As discussed in this newsgroup thread , the solution (until 2.2 is released), is to download rcp-report-designer-2.2.0 and copy the oda-jdbc.jar found in: birt-rcp-report-designer-2_2_0\plugins\org.eclipse.birt.report.data.oda.jdbc_2.2.0.v20061009-0630 and replace the oda-jdbc.jar found at: eclipse\plugins\org.eclipse.birt.report.data.oda.jdbc_2.1.1.v20060922-1058 You will need to replace the oda-jdbc.jar in the webviewer if you are using it. I would have upgraded to 2.2M1 if the webviewer was working right.
