}Build tools

In main folder Maven installation was successful

Solution: Change the C:/mark.homepc into the path of commen_built.xml in main pom.xml

Solution:Change the path of glassfish in the main pom.xml without /bin

This error is to be resolved. We have asked author for the help in special google group SOA Using Java Web Services

Errors due to backward slash(/) instead of forward slash(\) for setting path

Space in path name (Ex. C:\Documents and settings)
