Hi,
I am having trouble with hibernate while generating hibernate mappings.
When I generate the Java class and the xml file using Myeclipse database explorer I get 2 java files.

I don’t want 2 files, I just need one file with one xml file. I read many hibernate books and they all had one java file. first time I see a file like “Databaseconnection.java” below. I want a file like “DatabaseconnectionId.java”.

do I have to do any configuration for Myeclipse database explorer to get only one file? thanks.

——————– Databaseconnection.java —————–
package hibernate;

/**
* Databaseconnection generated by MyEclipse – Hibernate Tools
*/

public class Databaseconnection implements java.io.Serializable {

// Fields

private DatabaseconnectionId id;
// Constructors

/** default constructor */
public Databaseconnection() {
}
// Property accessors

public DatabaseconnectionId getId() {
return this.id;
}

public void setId(DatabaseconnectionId id) {
this.id = id;
}

——————– DatabaseconnectionId.java —————–

package hibernate;

/**
* DatabaseconnectionId generated by MyEclipse – Hibernate Tools
*/

public class DatabaseconnectionId implements java.io.Serializable {

// Fields

private long connectionid;
private String url;
private String driver;

// Constructors

/** default constructor */
public DatabaseconnectionId() {
}

/** minimal constructor */
public DatabaseconnectionId(long connectionid) {
this.connectionid = connectionid;
}

// Property accessors

public long getConnectionid() {
return this.connectionid;
}

public void setConnectionid(long connectionid) {
this.connectionid = connectionid;
}

public String getUrl() {
return this.url;
}

public void setUrl(String url) {
this.url = url;
}

public String getDriver() {
return this.driver;
}

public void setDriver(String driver) {
this.driver = driver;
}

public boolean equals(Object other) {
if ( (this == other ) ) return true;
if ( (other == null ) ) return false;
if ( !(other instanceof DatabaseconnectionId) ) return false;
DatabaseconnectionId castOther = ( EDatabaseconnectionId ) other;

return (this.getConnectionid()==castOther.getConnectionid())
&& ( (this.getUrl()==castOther.getUrl()) || ( this.getUrl()!=null && castOther.getUrl()!=null && this.getUrl().equals(castOther.getUrl()) ) )
&& ( (this.getDriver()==castOther.getDriver()) || ( this.getDriver()!=null && castOther.getDriver()!=null && this.getDriver().equals(castOther.getDriver()) ) );
}

public int hashCode() {
int result = 17;

result = 37 * result + (int) this.getConnectionid();
result = 37 * result + ( getUrl() == null ? 0 : this.getUrl().hashCode() );
result = 37 * result + ( getDriver() == null ? 0 : this.getDriver().hashCode() );
return result;
}

The reason you get two files is because you are using a code-generation tool. If you want to make customizations to the generated files, you need to put those customizations in the concrete subclass. That way if you add a few methods, then regenerate your mappings, only the abstract base classes get overwritten.
