title: Ant build failing when upgrading to weblogic 10.3.6
body: <p>We have an existing application which has an ANT script used for deployment and running on weblogic version 9.2.3.</p>
  
  <p>We had a request to upgrade the weblogic to version 12.1 and I was able to successfully upgrade this by changing the application specific WL_HOME and giving the build using the ANT script already present. But unfortunately we were having a dependency on another application that is running on weblogic 8.1 and weblogic 12.1 is not compatible with 8.1.</p>
  
  <p>So we are now in the process of downgrading the weblogic to version 10.3.6 and after installation of weblogic 10.3.6, I changed the same application specific property WL_HOME to point to weblogic 10.3.6 and tried the ANT build.</p>
  
  <p>But this time the ANT script failed, throwing errors saying error: <strong>package javax.ejb does not exist
  import javax.ejb.CreateException;</strong></p>
  
  <p>The application and weblogic is installed in a solaris/unix machine and we are using jdk 1.7.0.60 for the application.</p>
  
  <p>I am not an expert on weblogic or ANT, and I couldn't figure out where I went wrong. I see that we have javax.ejb_3.0.1.jar present in the modules directory. </p>
  
  <p>It will be really grateful if somebody could let me know where I might have gone wrong.</p>
  
  <p>Thanks for your help in advance.</p>
