Trying to deploy- jre missing

Report · Nov 17, 2010

Hi, I am following the test drive tutorial and it says to go to deploy and packaging and na

vigate to the car file. When I do,

CF complains and says JRE is not installed

. I had downloaded the jdk as instructed elsewhere

. I have never used CF or java so don't know whether it is installed and misconfigured, or not installed. (I suspect the former).

I ran javac at the command prompt and I got a list of parameters (if this proves anything).

I would like to know how to do the following:

1 Prove whether i have jre installed

2 Prove whether the plug-ins are installed

3 Know where to configure these for CF

Thanks in advance

I think the warning you are getting regards that you don't have a JRE that

your browser can use, having nothing to do with the JVM/JDK that ColdFusion

is using. When you navigate to that page in the CF Admin you are clicking a

button that says BROWSE. That takes you to a page where a Java Applet is

loaded in the browser and is intended for you to navigate the file system to

pick the *.car file.

Go to this web page:

http://www.oracle.com/technetwork/java/javase/downloads/index.html

Find the table at the top showing "Java Platform, Standard Edition" and

click on the button on the right for Download JRE (not the one for JDK).

Install that (probably requires closing your browser), then try the CF Admin

again.

Hope that helps.

Hi Steve

Many thanks for that. I had not considered it a browser problem.

Actually, reinstalling the JRE didn't solve the problem but it gave me an idea.

I launched a Safari browser and opened the admin page in that and tried to deploy.

This time, it prompted me and although saying java wasn't installed it offered to install it.

I clicked yes and it went through the same but from a different site.

It then offered to verify that it was installed, so I did, and it was.

I then logged out of admin and opened in IE8 and it then worked fine.

Strange. Perhaps it was a 64bit thingy.

I am pleased. I can get on with my tut now 🙂

Thanks

Tom
