Dear all,
I'm trying to upgrade my production server from dbforms 1.1.4pr1 to
1.1.4pr2 (2003.12.13 build).
I've a strange problem when I substitute the dbforms1.1.4.pr1.jar lib (in
WEB-INF/lib) with the new one dbforms1.1.4pr2.jar.
With the first one the software is OK, when I try the version 1.1.4pr2 I
get errors.
The error in a simple JSP page is this:
-------------------------
type Exception report
message Internal Server Error
description The server encountered an internal error (Internal Server
Error) that prevented it from fulfilling this request.

I analyzed by hand the file user_win_single_ro_jsp.java on line 121 where
I have this set of instructions:
/* ---- db:dbform ---- */
org.dbforms.taglib.DbFormTag _jspx_th_db_dbform_0 =
(org.dbforms.taglib.DbFormTag)
_jspx_tagPool_db_dbform_tableName_maxRows_followUp_autoUpdate.get(org.dbforms.taglib.DbFormTag.class);
_jspx_th_db_dbform_0.setPageContext(pageContext);
_jspx_th_db_dbform_0.setParent(null);
_jspx_th_db_dbform_0.setAutoUpdate("false");
_jspx_th_db_dbform_0.setFollowUp("/business_objects/users/users_win_single_ro.jsp");
_jspx_th_db_dbform_0.setMaxRows("1");
_jspx_th_db_dbform_0.setTableName("users"); <<======== PROBLEM !!!!
int _jspx_push_body_count_db_dbform_0 = 0;
try {.................
the "users" is the table of my database. In DbFormTag.java the error is on
this rows:
public void setTableName(String tableName) {
this.tableName = tableName;
this.table = config.getTableByName(tableName);
this.tableId = table.getId(); <<========== PROBLEM !!!!
}
The dbforms-config.xml file is the same with 1.1.4pr1 test and with 1.1.4pr2.
I put in the footer of this mail the JSP page and the piece of
dbforms-config.xml that regards the "users" table.
This error is happening with any other JSP page.
PS.
I'm using Linux to develop (with eclipse 3.0m4) and I've problems to
debug tomcat apps.
Have you any idea about this problem?
Many thanx
Ivan
