I have a situvation where i need to compile classes dynamically.

Following is the structure in which my java classes have been organized.
// no package public class A{ } package test ; public class B{ A obj; //other java code }
where A is a class with default package, and B is a class with package name test. B has A as a attribute.

Files are saved in their respective folders( as per package )

I fail to compile this with JAVA Compiler API.

Any help !!

check you antlr version. that seems to be the problem. which version of weblogic are you using?

Hi,

I have added filtering clasloader( weblogic-application.xml with <prefer-application-packages> <package-name>org.apache.log4j.*</package-name> <package-name>antlr.*</package-name></prefer-application-packages>) after doing this, i am getting a ClassNotFoundException on server stop. I have the hibernate jar file in the web application lib direcotry.
This is the structure of my application.
Sample.ear
META-INF
weblogic-application.xml
application.xml
test.war
WEB-INF
lib
hibernate3.jar
..........

all the other functions work well. but this is irritating on the server stop.
Any help would be greatly appriciated.

Hi Ravish,
Thnks for the reply. I have the hibernate.xxxx.jar in my lib directory. And use hibernate extensively in my application. how ever i see this only on server stop.

i get the following execption while stoping the weblogic 10.3.2 server.
