Re: Problem with ejbc and jikes

2001-09-19 Thread Saneesh Joseph 

Hi Kapil,
Thanks for your reply , and I do really appreciate it.
Your workaround suggestion is cool, but the question
is how... The problem is that the TopLink CMP java
files are generated during the ejbc step and also, if
we exclude these files from being compiled and have
them compiled as a separate step, will we still be
gaining time.. I am not sure how to exclude files
which are not existing at the time of ejbc.. Anyway,
let me give it a shot, and I will let you know..
Regards,
Saneesh J.

 The reason for this is that while compiling the

 interdependencies (this does not 
 happen for Jikes). I once encountered a similar
 problem and worked aroung 
 by splitting the javac of the .java files into
 multiple parts. 
 
 In your case EbeanPSTopLink.java needs EbeanPS.class
 for compilation (only 
 in case of Jikes, javac resolves this
 automatically). However the 
 compilation of EbeanPS.java goes happens only after
 EbeanPSTopLink.. 
 
 A workaround in your case can be to exclude
 EbeanPSTopLink during first 
 round of javac and add one more javac task for
 this file alone. 
 
 But I am sure there must be a better way of doing
 this :-)

 Subject:Problem with ejbc and jikes
 
 
 Hello,
 I am trying to use jikes compiler in my ant ejbc
 step 
 to make it faster. Our current build takes close to
 an
 hour. We are using Toplink for Weblogic for CMP. I
 am
 supplying all the toplink xml-descriptors, ejb-jar
 and
 weblogic xmls and the home,remote and implementation
 classes in one jar(which comes to around 400 files)
 as
 the input to ejbc. During ejbc, TopLink creates some
 java files for its use and compiles them, which are
 inturn used by some other similarly generated java
 files. For example, lets assume we have an entity
 bean
 Ebean. Toplink creates class EbeanPS.class and
 another
 javafile EbeanPSTopLink.java which implements
 EbeanPS.
 Now, when I am using the regular javac/classic
 compilers, it is going through fine. But, when I am
 using jikes as the compiler, it doesn't go through
 saying that While compiling EbeanPSTopLink.java, it
 couldn't find EbeanPS.class. Now, when I examined
 the
 ejbcgen directory, I could see the required class
 under it. I tried giving the ejbcgen directory in
 the
 classpath, but ejbc errored out saying that the
 destination file of ejbc can't be given in
 classpath.
 The following is the step which I am using in my
 build.xml :-
 java classname=weblogic.ejbc 
   fork=yes 
   failonerror=yes
   classpathref=project.class.path
  
arg value=-compiler /
arg value=jikes /
arg value=-nowarn /
arg value=Beans.jar /
   arg value=BeansEJBC.jar /
 /java
 Any help on the above issue is greatly appreciated..
 Thanks and Regards,
 Saneesh J.

The property ejbc.compiler is set to either jikes or javac.  Which is 
actually quite annoying since I also use a property for the compiler in the 
javac tasks and must be set to either jikes or modern (javac not 
being legal but should be an alias for modern or perhaps classic).

Don't forget that Jikes needs the rt.jar in the classpath.  And of course 
all of the classes used must be accessible in the classpath too, regardless 
of which compiler.

2001-09-18 Thread Saneesh Joseph 

Hi Jim,
Thanks for the reply. I had tried using ejbjar task as
you have written.. The problem is , my input classes
and descriptor files are in a single jar, so, I can't
give it in the srcdir parameter. I believe the basejar
name is the jar name that has to be created. Also
could you please explain why we need to have a
separate ejb classpath in the weblogic element, and
what should it constitute.. Right now, I have every
class required as part of the classpath. Yes, I do
have the rt.jar in my classpath. I am able to
successfully compile all my java files using jikes in
a previous step. Only ejbc is giving a headache..

Re: Problem with ejbc and jikes

2001-09-18 Thread Jim White 

Hi Saneesh.

Sorry I don't have more help to offer.  While I've seen the While 
compiling Foo, can't find Bar, I don't remember anything more specific 
about it.  Pretty sure it is some classpath issue.  That path element I use 
also includes /weblogic/classes:

path id=weblogic.classpath
pathelement path=${weblogic.lib}/weblogicaux.jar/
pathelement path=${weblogic.classes}/
/path

Plus I think the ejbjar task also does some additional classpath fiddling.
