javac cannot find package even though it is present in the classpath

Hi,
 
    I started working on ant about a week back. I use
ant on Win NT. I am facing a fairly strange problem. I
use javac to compile few jav files, out of which a
file imports the package 'oracle.jdbc.*'. This package
is contained in the file classes12_01.jar. Even though
classes12_01.jar is in the system Classpath it can't
seem to find it, and gives the following error -
.
.

The classpath displayed here shows that
classes12_01.jar is present in the classpath. When I
compile the same file at the command prompt using the
same iPlanet javac, it compiles fine.

Does anyone have suggestions on what I may overlooking
here.

Thanks,
  Dominic

I am not sure if this is the cause but I noticed that you had duplicates of
a lot of jars. This can cause problems with some VMs (usually 1.3+) so try
removing all duplicates from classpath and retrying ?


Cheers,

Pete

Re: javac cannot find package even though it is present in theclasspath

Posted by John Colgrave <co...@hursley.ibm.com>.
This is how I compile code against j2ee.jar:

<target name="classes" depends="prepare">
    <javac srcdir="${src}/Java"
           destdir="${build}/classes">
        <classpath>
            <pathelement location="D:/j2sdkee1.2.1/lib/j2ee.jar"/>
        </classpath>
    </javac>
</target>

I prefer to have explicit control over the classpath rather than relying on the
system classpath.  I usually have other things (other pathelements or other
paths) in the classpath also but this is all that you need for j2ee.jar.

RE: javac cannot find package even though it is present in the classpath

Posted by Todd Feather <to...@yahoo.com>.
I'm fairly new to Ant as well,  so take this as the hack that it is.

I had the same problem recently on a project I was working on. My compile
was also fine from the shell.

I tried a bunch of different things, but could never get it to work with a
JAR file. (In my case I needed the j2ee.jar file.)

I may be missing an easier way to deal with this, but I had to unjar the
files for the compile to work within Ant. I'm building to a JAR, so it
wasn't that terrible since I was going to re-jar everything to deploy it
anyway, but it is certainly not an ideal approach.

I hope someone can respond with the "correct" solution.


Todd
