Dear list,
I have problem concerning ImageJ/Java + WinXP account with restricted rights. Since not long ago, it's not possible to start ImageJ. The error message sounds as following: Java Virtual Machine Launcher "Could not find the main class. Program will exit." I'm using WinXP Prof SP2, newest updates, Java 5 Update 7, newest ImageJ. As far as I learned from googling this error message, the problem should be that the Java loader couldn't find the necessary ImageJ class. Changing the user rights on ImageJ and Java folder to "full access" doesn't help. I'm not very much into Java, so could please anyone help me? Thanks a lot in advance, Michael _____________ Michael Weber (B.Sc.) ..MTZ (before 12.30 pm)..

Hi there,
I´m new to ImageJ, and in this list. But okay in java. hope this works. 1st solution: in command mode "start"button "execute" type "cmd" and hit Enter Key. this will give you the command prompt. paste/type this comand: *set CLASSPATH=%CLASSPATH%;.* if doesnt works *set CLASSPATH=%CLASSPATH%;"c:\Program Files\ImageJ\"**(there may be more sub-directories here)* 2 solution: My guess is to add to java classpath './' (dot slash) or '.' (dot). This is accessible thru "administrative tools" or right click on my computer and proprieties, them you must find system variables, its a buttom. I´m not quite sure, I got this out of my head. I hope this works. BTW: any knows new trends on papanicolau (semi/automated) screening? Its my final work subject. Leonardo Schenkel - Computer Science Bachelor.

Try downloading and installing the version of ImageJ for Windows
bundled with Java 5.0_06 at <http://rsb.info.nih.gov/ij/download.html>. -wayne > I have problem concerning ImageJ/Java + WinXP account with > restricted rights.

My understanding is that I only need the JRE, not the JDK, or am I wrong at this point? Michael -- Michael Weber (B.Sc.) ..MTZ (before 12.30 pm)..

On Windows, the Plugins>Compile and Run command will not work unless you install the JDK, or use a version of ImageJ bundled with Java. The Java compiler is in tools.jar, which is not included with the JRE. -wayne |
