Re: Problems with ejbdoclet when there are no files under the merge directory

Hi,

your problem seems to have a simple solution to me: The directory you 
specify probably does not exist at all. Middlegen is pright then. Note the 
use of "/" and "\" in the path 
D:\OPENSOURCES\middlegen-2.0-vo\umo/src/middlegen/cmp20-countries-class-code.txt 

Middlegen probably checks the mergedir for matching mergefiles for every 
Bean Class. It does then not find the directory and warns you with this 
message. Xdoclet somehow gets upset with the "\" in the comment.
So it should work if you specify the right path.

Cheers.

        Thema:  [Middlegen-user] Problems with ejbdoclet when there are no 
files under the merge directory


Dear all,

I'm using middlegen to generate entity beans from a db connection. Inside 
the middlegen ant task, I've got the following nested element:

<cmp20
            destination="${build.gen-src.dir}"
            package="${name}.ejb"
            interfacepackage="${name}.intf"
            jndiprefix="${unique.name}"
            pkclass="true"
            dataobject="false"
            valueobject="true"
            mergedir="${basedir}/src/middlegen"
            sessionfacade="false"
            viewtype="local"
            readonly="false"
            fkcmp="true"
            guid="true"
         >

Please notice the 'mergedir' attrribute. In the case I haven't got any 
files 
under the merge directory, each entity bean is generated with the 
following 
comment
as last line:

  // No 
D:\OPENSOURCES\middlegen-2.0-vo\umo/src/middlegen/cmp20-countries-class-code.txt 

found.

Except from the names that are local to my computer, the substance doesn't 

change. When ejbdoclet executes on the entity bean source which contains 
the 
above comment as last line, it fails with the error show below:


ejbdoclet:
    [mkdir] Created dir: 
D:\OPENSOURCES\middlegen-2.0-vo\umo\build\ejb-meta

I found that a possible solution is to eliminate the mergedir attribute 
from 
the cmp subelement. However, this doesn't seem to me the optimal solution, 

especially in the case where I *need* a merge dir for some files but not 
for 
others. It would help if the comment which gets autogenerated would be 
written without Java escape symbols ('\').

If you tell me where this line gets generated, I may update the code and 
submit a patch.

Regards,

Marco
