[xmlbean] scomp giving me an exception: java.io.IOException: CreateProcess

Hi, I am trying to generate the xmlbeans classes from my schema file Mpg-pvc.xsd,
using scomp, and I get the following error.
It is really annoying, I do not know where the problem is and I just started with xmlbeans.

Can anyone help me here ?
Thanks in advance

Here is the message I get:

I have not used scomp (much less know what it is used for) but since its an IOException, I would think the process is not able to access the required files or it may not be having the right permissions to write to that dir.
Just guessing......

Does that "tool" come with any documentation at all?

Can you run scomp OK against the xmlbean supplied samples?

Post your xsd please.

hey,
it's been more than a month that I posted this message.
I figured it out, I could generate the API, I got the correct options
for the scomp command under DOS.

Thanks a lot for your help anyways

First I would let you know the solution and discuss about the problem
Solution : C:> scomp -d D:\JarXml -out Event.jar Event.xsd
where JarXml should be a empty directory.

Reason:
On investicating I found an interesting thing, if you should use empty directory for -d, like -d d:\, scomp just take all the files in D: and try to make the jar.
In my case earlier I used to put -d D:\,
C:>scomp -d D:\ -out Event.jar Event.xsd
so it doesn�t know which two directory it creates and so it tries to generates JAR from all the directory in the D:, and end up in IO Exception.

Typically it create two directory namely com andJarXml.
Hope this helps.
One more information, I use NTFS file system, it seems people use other files system may not get this error.

The reason is for NTFS it tries to create C:\DOCUME~1\GOWRIS~1\LOCALS~1\Temp\xbean31056.d\classes\schemaorg_apache_xmlbeans\javaname\xxx\xx
ending up in org.apache.xmlbeans.SchemaTypeLoaderException.

The solution to this problem (Windows)is, Java JDK PATH is not set properly in the PATH environment variable or it may not be the first environment variable.

Please keep JDK path always at the first place in the PATH environment variable.

PATH=C:\j2sdk1.4.2_03\bin;

If there is a space in your JAVA_HOME like C:Program Files, you may get this error.You have to use a JAVA_HOME directory with no spaces.

Without messing about with your enviroment variables you can explicitly set the compiler in scomp.

scomp -compiler path/to/your/javac.exe -out path/to/jar.jar path/to/schema/schema.xsd

I couldn't get the environment variable thing to work for the life of me, but explicitly setting the compiler worked like a charm for me (thank you, by the way)!
