Problem: Seam Generate Entities !

[allforjava.allforjava.aol.in]

Hi,

I hv used "Seam Genetrate Entities" to reverse engineer from database. The relavant .xhtml and xml with .java files are generated.

However in some of the auto-generated java codes (bean), the datatype of the attributes/class variables is "double" and where as the datatype of the respective column in the database table is as "float".

The earlier generated (and enchanced code) is same as I hv generated newly. But the newly genarated one is not working and where as the old one is still working fine.

Kindly suggest how to deal with it?

I guess because of this the deployment if failing, with followig error message.

`

     }

     public void setPercentageComplete(double percentageComplete) {
          this.percentageComplete = percentageComplete;

You need to customize the <type-mapping>. Have a read to Hibernate documentation for reveng.xml file.

why don't you try and change it manually to java float in the entity ?

I'll be having the final attempt as suggested. But the thing is that the older codes generated vide Seam Generate Entities is workingfine with same code. So why it should not with the freshly/newly generated copy? Any other suggestions?

I usually use the project generated by seam-gen on the command line (see {SEAM_HOME}/seam-gen/): the file is called seam-gen.reveng.xml. I never used the Eclipse Wizard with this file so I don't know where it is.
