Well, one person thought adding "select for update" on Entity Loading to
JAWS would be useful so I looked into it. It's a rather simple change
if anybody thinks it worth adding to CVS(I don't have rw access). I
thought it would be useful to be able to turn "select for update" on or
off for specific entity beans. It can be turned off/on the same way
tuned-updates or read-only can be turned off/on. The xml tag I selected
was <select-for-update>. If read-only is turned on select-for-update
will always resolve as false.

In org.jboss.ejb.plugins.jaws.jdbc.JDBCLoadEntityCommand
change the constructor adding this code to the end
sql += " FROM "
+ jawsEntity.getTableName()
+ " WHERE "
+ getPkColumnWhereList();
//--start new code
if (jawsEntity.hasSelectForUpdate())
{
sql += " FOR UPDATE";
}
//--end new code
setSQL(sql);
In org.jboss.ejb.plugins.jaws.metadata.JawsEntityMetaData
1. Add a member variable
private boolean selectForUpdate;
2. Change importXML()
// read only? If not provided, keep default.
String roStr = getElementContent(getOptionalChild(element,
"read-only"));
if (roStr != null) readOnly = Boolean.valueOf(roStr).booleanValue();
//---start new code
String sForUpStr = getElementContent(getOptionalChild(element,
"select-for-update"));
if (sForUpStr != null) selectForUpdate =
(Boolean.valueOf(sForUpStr).booleanValue()) && !readOnly;
//---end new code
3. add accessor for selectForUpdate
public boolean hasSelectForUpdate() { return selectForUpdate; }
