Keep getting: weblogic.xml.schema.binding.BindingException: ERROR: during code compilation

[Jay Dilla]

I'm running a ant build on some files and I keep getting this error and can't figure out why. I've verified that weblogic.jar, wlclient.jar, and webservices.jar are all in the classpath
I've run the setEnv.cmd and it did nothing. I verified that my environment variables have the right JDK and ant version. Is there anything else I need to check here?

Also checked the build.xml itself to see what it was referencing and it's looking for the weblogic jars in the proper location.
I think I've had this happened before and was able to fix it but I don't remember what I did, anyone ever get this before and get rid of it? I'm guessing it's something in my set up since I got the project from off SVN and other people are able to compile using ant right out the box.


ant version is 1.7.1
jdk is 1.6.0_24 (required)
weblogic version is 10.3.4 (required)

[Jay Dilla]

I also see this in my build.xml when I load it in my IDE:

taskdef class weblogic.ant.taskdefs.j2ee.Appc cannot be found

i get that kind of error for each of the below lines

 <taskdef name="wlappc" classname="weblogic.ant.taskdefs.j2ee.Appc" classpathref="wls.libraries"/>
    <taskdef name="servicegen" classname="weblogic.ant.taskdefs.webservices.servicegen.ServiceGenTask" classpathref="wls.libraries"/>
    <taskdef name="clientgen" classname="weblogic.ant.taskdefs.webservices.clientgen.ClientGenTask" classpathref="wls.libraries"/>
    <taskdef name="autotype" classname="weblogic.ant.taskdefs.webservices.javaschema.JavaSchema" classpathref="wls.libraries"/>

wls.libraries is set to the right path. why can't it find it?

[Jay Dilla]

Fixed it. Issue was / vs \ in my build property file

wls.home = c/bea.... vs c\bea.....

Thanks for sharing the solution
