Re: [aspectj-users] running compiler in java application

[George Harley1 <GHARLEY@xxxxxxxxxx>]

D'oh ! I made a mistake in the sample
code. The for loop at the end has an incorrectly named variable. For clarity,
please change variable identifier "problemMessages" to "problems"
like this ...


       
        // Now just process the messages ....
               for (int i=0 ;
i<problems.length ;i++) 
                {
                    ISourceLocation
s = problems[i].getSourceLocation();   
                    ..
etc ... etc ... 

                }// end for 

Best regards,
George

Dear Sir, 

Yes, it is possible using the AspectJ compiler API (see http://dev.eclipse.org/viewcvs/indextech.cgi/~checkout~/aspectj-home/doc/devguide/ajc-ref.html#d0e575).
The way I have used it in the past looks something like this ... 


            // Create a new Main together
with a message holder to enable access to any compiler messages.
            org.aspectj.tools.ajc.Main ajCompiler
= new Main(); 
            org.aspectj.bridge.IMessageHolder
msgs = new MessageHandler(); 
            ajCompiler.setHolder(msgs);

            // Build up your compiler switches
and arguments... 
            ArrayList argsList = new ArrayList();
            argsList.add("-inpath");
            argsList.add("c:\dev\foo.jar");
            argsList.add("-outjar");
            argsList.add("c:\dev\outputs\foo-woven.jar");
            argsList.add("-classpath");
            argsList.add("c:\dev\jars\A.jar;c:\dev\B.jar");
            
            // ...and then put them into
an array of strings   
            String[] argArray = (String[])
argsList.toArray(new String[]{}); 

            // Run the compiler
            ajCompiler.runMain(argArray,
false); 

            // Now get any messages out of
the IMessageHolder 
            if ( msgs.numMessages(IMessage.WARNING,
true) > 0 ) 
            { 
                IMessage[] problems
= 
                    msgs.getMessages(IMessage.WARNING,
true); 

                // Now just process
the messages .... 
               for (int i=0 ;
i<problemMessages.length ;i++) 
                {
                    ISourceLocation
s = problemMessages[i].getSourceLocation();   
                    ..
etc ... etc ... 

                }// end for 
            }// end if


Hope this helps (and that the code formatting doesn't get messed up in
transit). 

Best regards, 
George

Hi, 
  
does anyone know, if there is a possibility to run "ajc" directly
within an other Java application? 
  
Cheers, 
    Sir
