[Tony Evans]

I am trying to build poolman a tool that u can use with tomacat it pools databse connections>

When I try to build the application I get the following error message:


C:\poolman-2.0.3\build>build
Buildfile: build.xml

init:

prepare:

compile:
[javac] Compiling 48 source files to C:\poolman-2.0.3\bin
[javac] Modern compiler is not available - using classic compiler

BUILD FAILED

C:\poolman-2.0.3\build\build.xml:49: Cannot use classic compiler, as it is not available A common solution is to set the environment variable JAVA_HOME to your
jdk directory.

Total time: 1 second
C:\poolman-2.0.3\build>

when I do this:

C:\poolman-2.0.3\build>echo %JAVA_HOME%
C:\jdk1.3

C:\poolman-2.0.3\build>

Why is ant throwing up this message.

Thanks for any help Tony

Poolman may be expecting the jsdk 1.4.

I'm not sure why it's failing, but there are several links on google about it.

For Ant, modern compiler is anything 1.3 and above, so it should work. Classic is 1.1 and 1.2.

Tony, I would check to make certain that %JAVA_HOME%/bin/javac exists and that the PATH environmental variable is set in your context and includes %JAVA_HOME%/bin .
