NullPointerException on Startup

[phowell]

 Hi,

I'm getting a null pointer exception when trying to start iReport v3.7.1 on Windows7 (64bit).

Is this the correct place to report this issue? I have attached the log file.

I noticed that the log file indicates that JRE 1.5 is being used, however my default JRE is 1.6 (i.e. when I type 'java -version' in a command window I shows java version "1.6.0_19" of the 64bit version of the Java HotSpot JRE). I do also have 1.5 JRE installed.

Also when iReport attempts to start the Windows desktop UI switches to a basic mode without the "Aero" effects.

Thanks,

Phil.

I avoid having multiple versions of Java installed; it usually ends poorly. Try:

1. Uninstall iReport.
2. Uninstall all versions of Java.
3. Install iReport 3.7.2.

4. Run iReport.

If it works, then:

5. Install version of Java you need.

6. Run iReport.

If it fails at 6, you have isolated the problem.

Phil,

thangalin's answer may work... but that's a pretty big sledgehammer to find a JDK issue.

Try editing the file ...\iReport-3.7.2\etc\ireport.conf

Set the jdkhome appropriately, and you should be all set.

Hi Matt,

 

Yep, that fixed it. I set:

 

jdkhome="C:\Program Files\Java\jre6"

 

In the conf file and all is good.

 

Thanks,

Phil
