URGENT!!!!!!!! Tomcat 5.0 does not connect to the database !!!!!!
We had an already existing system on tomcat 4.1.18. Since migrating to Tomcat 5.0, we are facing lots of problem while trying to connect to the database. The database in SQL Server 2000.
The first time i try to connect (after restarting tomcat service) the system is able to connect to the database but after sometime it again stops connecting.
The beans on our system are able to connect to the database without any problem but when we try using the same via http, it doesnt connect. The classpath is set properly. Also the database drivers are also the latest ones and in the proper place. We have placed them in the common/lib folder. We have checked that normal jsp pages which are not connecting to the database are working fine.
Please HELP!!!!!!!!!!!
Thanks in advance
well.....Tomcat is not a database connecting engines.....U would need to check your db connection codes to check if you have missed anything.....so the first question will be
1. How do u connect to the DB
2. Which type of JDBC drivers are u using.
Finaly, tomcat is not at fault...its the fault of you configuration
Cheers,

How do i fix my wifi if it connects and the bars are blue but no check sign appears next to the wifi name and does not connect to the internet???
Did you already try to reset the iPod by holding the sleep and home button for about 10sec, until the Apple logo comes back again? You will not lose data.
If this does not work, try to reset the network settings in Settings/General/Reset. After that you'll have to put in the passwords for all known networks again.

iOS: Troubleshooting Wi-Fi networks and connections -
My home wireless is no longer recognized, even going through the set-up process. It does not connect to the car through Bluetooth seamlessly--I have to add my phone as a new device each time I get in the car. In attempting to solve these problems I have gone to settings-phone-upgrade and it states that the upgrade is available-select to continue-(which I do)- it checks -please wait and it then states that update not available - try later.
Maybe not too late to help you.
For specifically fixing the Bluetooth, un-pair your phone with the car, and go through the process of repairing the two.
In general, the KK update requires many of us (different phones) to perform a Factory Data Reset after we back up our personal content (pictures, music, movies, or other downloaded files) to a PC or MAC. This will result in you having to do a bit of work to setup icons for the programs you use, and maybe putting in the specifics again for email accounts and other specialized apps. So if you are going to do this sort of thing... copy important information/settings down on paper.

TS3276 iCloud email on OSX 10.8 does not connect to the server after sleep
iCloud email on OSX 10.8 does not connect to the server after sleep. The only way I can reconnect the iCloud email is to restart the computer. Does anyone have any ideas how to resolve this issue?
I would suggest you try opening "Mail">click on "Mailboxes" in the Menu Bar> and select "Rebuild" from the list. That may solve it.

Ich still shows the 3G symbol but I cant connect to the internet anymore. Since ios 5.1 it disconnected every 30 minutes untill i restarted. De- and reactivating the mobile internet never helped. Now i dont get a connection. It quite not works.
I never had problems untill ios 5.1
of course apn, username and passwort for the carrier are correct.
My carrier is simyo
(im in germany)
Thank you for helping meHi Damien,
Thanks for your reply.
I had not created 2 separated wireless network. The airport extreme has had create wireless allowing it to be extended and the airport express has had it to extend since day 1.
The only device that does not connect to the airport express when it is far from the airport extreme here is the iPhone 4. I've tested 2 Windows based computers, 2 Macs, 1 Samsung TV and 1 Android phone and they all are able to connect to the airport express when the signal from the airport extreme is weak (please take a look on the screen shots on the original post).
The screenshots of the 2 devices' wireless set up can be found below:
Airport Extreme
Airport Express
I have seen other people here on the Apple discussions complaining about the same issue with their iPhone 4 and iPad: would it be a iOs problem?

EJB 3.0 - JSF APPLICATION: DATA DOES NOT PERSIST TO THE DATABASE
Hi,
I am developing a JSF - EJB application and the data that I send from JSP Page through JSF Managed Bean --> Session Bean --> Java Persistence does not persist in database.
Here is my scenario ( Iam using JDeveloper IDE to create this application) -
SCENARIO START
The scenario consists of two web pages, one enlisting all the users stored in the database, the other contains a form for adding a user
1.) INDEX.JSP
2.) ADDUSER.JSP
Step 1: Create the USERS Table in database
CREATE TABLE users
user_id serial,
username varchar(255) NOT NULL,
first_name varchar(255),
last_name varchar(255),
password char(64) NOT NULL,
CONSTRAINT pk_users PRIMARY KEY (user_id)
Step 2: Add Database Connection To JDeveloper
Go to Database Connection Navigator and create a New Database Connection using the Wizard
Step 3: Create a New Application in JDeveloper and select JSF, EJB from Application Template
Step 4: ENTITY BEAN - In the EJB Node Right Click and Select EJB à New Entites from Table (JPA/EJB3.0)
Use The Wizard and create Entity Bean from Users Table which creates an Entity Bea POJO file as follows –
User.java -
package lux.domain;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.NamedQuery;
import javax.persistence.SequenceGenerator;
import javax.persistence.Table;
@Entity
@NamedQuery(name = "User.findAll", query = "select o from User o")
@Table(name = "USERS")
public class User implements Serializable {
@Column(name="FIRST_NAME")
private String firstName;
@Column(name="LAST_NAME")
private String lastName;
@Column(nullable = false)
private String password;
@Column(nullable = false)
private String username;
@Id
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="users_seq_generator")
@SequenceGenerator(name="users_seq_generator", sequenceName="users_user_id_seq")
@Column(name="USER_ID", nullable = false)
private Long userId;
public User() {
public String getFirstName() {
return firstName;
public void setFirstName(String firstName) {
this.firstName = firstName;
public String getLastName() {
return lastName;
public void setLastName(String lastName) {
this.lastName = lastName;
public String getPassword() {
return password;
public void setPassword(String password) {
this.password = password;
public String getUsername() {
return username;
public void setUsername(String username) {
this.username = username;
public Long getUserId() {
return userId;
public void setUserId(Long userId) {
this.userId = userId;
Step 5: STATELESS SESSION BEAN - In the EJB Node Right Click and Select EJB à New Entites from Table (JPA/EJB3.0)
Again Right Click on Model and create Session Bean from Wizard which creates two files –
UserDAOBean.java – Stateless Session Bean
UserDAO.java – Local Interface
package lux.facade;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.util.List;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.persistence.Query;
import lux.domain.User;
@Stateless(name="UserDAO")
public class UserDAOBean implements UserDAO {
@PersistenceContext(unitName="Model")
private EntityManager em;
public UserDAOBean() {
public User getUser(int UserId) {
User u = new User();
u = em.find(User.class, UserId);
return u;
public List<User> getAllUsers() {
Query q = em.createQuery("SELECT u FROM User u");
List<User> users = q.getResultList();
return users;
public void createUser(User u) {
String hashedPw = hashPassword(u.getPassword());
u.setPassword(hashedPw);
em.persist(u);
public void updateUser(User u) {
String hashedPw = hashPassword(u.getPassword());
u.setPassword(hashedPw);
em.merge(u);
public void deleteUser(User u) {
em.remove(u);
private String hashPassword(String password) {
StringBuilder sb = new StringBuilder();
try {
MessageDigest messageDigest = MessageDigest.getInstance("SHA");
byte[] bs;
bs = messageDigest.digest(password.getBytes());
for (int i = 0; i < bs.length; i++) {
String hexVal = Integer.toHexString(0xFF & bs);
if (hexVal.length() == 1) {
sb.append("0");
sb.append(hexVal);
} catch (NoSuchAlgorithmException ex) {
Logger.getLogger(UserDAOBean.class.getName()).log(Level.SEVERE, null, ex);
return sb.toString();
Step 6: Create a Deployment file in the Model and Deploy this to a JAR file
Step 7: Now Right Click on View/Controller Node and create a Java File –
UserController.java -
package lux.controllers;
import javax.ejb.EJB;
import javax.faces.model.DataModel;
import javax.faces.model.ListDataModel;
import lux.domain.User;
import lux.facade.UserDAO;
public class UserController {
@EJB UserDAO userDao;
private User user;
private DataModel model;
public String createUser() {
this.user = new User();
return "create_new_user";
public String saveUser() {
String r = "success";
try {
userDao.createUser(user);
} catch (Exception e) {
e.printStackTrace();
r = "failed";
return r;
public DataModel getUsers() {
model = new ListDataModel(userDao.getAllUsers());
return model;
public User getUser() {
return user;
public void setUser(User user) {
this.user = user;
Step 8: Configure page flow in faces-config.xml
1. Create the JSP file adduser.jsp by right-clicking View-Controller
node and selecting New > JSP. Use the wizard to create JSF – JSP Page, fill in
File Name adduser.jsp, click Finish. -
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">

</head>
<body>
<f:view>
<h:form>
<h:messages/>
<h:panelGrid columns="2">
<h:outputText value="Username"/>
<h:inputText

required="true"/>
<h:outputText value="First name"/>
<h:inputText
id="FirstName"
value="#{user.user.firstName}" />
<h:outputText value="Last name"/>
<h:inputText
id="LastName"
value="#{user.user.lastName}" />
<h:outputText value="Password" />
<h:inputSecret
id="Password"
value="#{user.user.password}"
required="true" />
<h:panelGroup/>
<h:commandButton
action="#{user.saveUser}"
value="Save"/>
</h:panelGrid>
</h:form>
</f:view>
</body>
</html>
2. Repeat the previous step for another JSP file failed.jsp.
3. On failed.jsp add the string
Save failed
Next we configure the page flow.
1. Open faces-config.xml.
2. Create index.jsp -
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>User Listing</title>
</head>
<body>
<f:view>
<h:form>
<h:outputText value="User Listing"/>
<h:commandLink action="#{user.createUser}" value="Create a user"/>
<h:dataTable value="#{user.user}"
var="dataTableItem" border="1" cellpadding="2" cellspacing="2">

<h:outputText value="#{dataTableItem.username}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="First name"/>
</f:facet>
<h:outputText value="#{dataTableItem.firstName}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Last name"/>
</f:facet>
<h:outputText value="#{dataTableItem.lastName}" />
</h:column>
</h:dataTable>
</h:form>
</f:view>
</body>
</html>
3. Drag an arrow from index.jsp to adduser.jsp and replace the arrow’s label to create_new_user.
4. Repeat the previous step for failed, by dragging and arrow from adduser.jsp to failed.jsp renaming the label to f
ailed
5. Finally repeat the step for adduser.jsp, by dragging from adduser.jsp to index.jsp renaming the label to success.
This creates the following faces-config.xml file –
<?xml version='1.0' encoding='UTF-8'?>
<faces-config>
<managed-bean>
<managed-bean-name>user</managed-bean-name>
<managed-bean-class>lux.controllers.UserController</managed-bean-class>

Step 9: Create a Deployment file in the View-Controller and Deploy this to a WAR file
Step 10: Create a Deployment file in the View-Controller and create an EAR file and add Model’s JAR and View-Controller’s
WAR files to it.
Step 11: Run the JSP Files
SCENARIO END
Now, When I execute Index.jsp, it does not list values from database and when I click on Create User link, it takes me to adduser.jsp page. When I fill values in this page and click Save button, it takes me to Save Failed page and data does not persist to the database.
WHAT IS WRONG OUT HERE ???If you set a breakpoint in your createUser method - does this code get executed?
We have a couple of tutorials that might show you how to do this.

EJB-JSF Application : Data does not persist to the database
Hi,
I am developing a JSF - EJB application and the data that I send from JSP Page through JSF Managed Bean --> Session Bean --> Java Persistence does not persist in database.
Here is my scenario ( Iam using JDeveloper IDE to create this application) -
SCENARIO START
The scenario consists of two web pages, one enlisting all the users stored in the database, the other contains a form for adding a user
1.) INDEX.JSP
2.) ADDUSER.JSP
Step 1: Create the USERS Table in database
CREATE TABLE users
user_id serial,
username varchar(255) NOT NULL,
first_name varchar(255),
last_name varchar(255),
password char(64) NOT NULL,
CONSTRAINT pk_users PRIMARY KEY (user_id)
Step 2: Add Database Connection To JDeveloper
Go to Database Connection Navigator and create a New Database Connection using the Wizard
Step 3: Create a New Application in JDeveloper and select JSF, EJB from Application Template
Step 4: ENTITY BEAN - In the EJB Node Right Click and Select EJB � New Entites from Table (JPA/EJB3.0)
Use The Wizard and create Entity Bean from Users Table which creates an Entity Bea POJO file as follows �
User.java -
package lux.domain;
import java.io.Serializable;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.NamedQuery;
import javax.persistence.SequenceGenerator;
import javax.persistence.Table;
@Entity
@NamedQuery(name = "User.findAll", query = "select o from User o")
@Table(name = "USERS")
public class User implements Serializable {
@Column(name="FIRST_NAME")
private String firstName;
@Column(name="LAST_NAME")
private String lastName;
@Column(nullable = false)
private String password;
@Column(nullable = false)
private String username;
@Id
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="users_seq_generator")
@SequenceGenerator(name="users_seq_generator", sequenceName="users_user_id_seq")
@Column(name="USER_ID", nullable = false)
private Long userId;
public User() {
public String getFirstName() {
return firstName;
public void setFirstName(String firstName) {
this.firstName = firstName;
public String getLastName() {
return lastName;
public void setLastName(String lastName) {
this.lastName = lastName;
public String getPassword() {
return password;
public void setPassword(String password) {
this.password = password;
public String getUsername() {
return username;
public void setUsername(String username) {
this.username = username;
public Long getUserId() {
return userId;
public void setUserId(Long userId) {
this.userId = userId;
Step 5: STATELESS SESSION BEAN - In the EJB Node Right Click and Select EJB � New Entites from Table (JPA/EJB3.0)
Again Right Click on Model and create Session Bean from Wizard which creates two files �
UserDAOBean.java � Stateless Session Bean
UserDAO.java � Local Interface
package lux.facade;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.util.List;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;
import javax.persistence.Query;
import lux.domain.User;
@Stateless(name="UserDAO")
public class UserDAOBean implements UserDAO {
@PersistenceContext(unitName="Model")
private EntityManager em;
public UserDAOBean() {
public User getUser(int UserId) {
User u = new User();
u = em.find(User.class, UserId);
return u;
public List<User> getAllUsers() {
Query q = em.createQuery("SELECT u FROM User u");
List<User> users = q.getResultList();
return users;
public void createUser(User u) {
String hashedPw = hashPassword(u.getPassword());
u.setPassword(hashedPw);
em.persist(u);
public void updateUser(User u) {
String hashedPw = hashPassword(u.getPassword());
u.setPassword(hashedPw);
em.merge(u);
public void deleteUser(User u) {
em.remove(u);
private String hashPassword(String password) {
StringBuilder sb = new StringBuilder();
try {
MessageDigest messageDigest = MessageDigest.getInstance("SHA");
byte[] bs;
bs = messageDigest.digest(password.getBytes());
for (int i = 0; i < bs.length; i++) {
String hexVal = Integer.toHexString(0xFF & bs);
if (hexVal.length() == 1) {
sb.append("0");
sb.append(hexVal);
} catch (NoSuchAlgorithmException ex) {
Logger.getLogger(UserDAOBean.class.getName()).log(Level.SEVERE, null, ex);
return sb.toString();
Step 6: Create a Deployment file in the Model and Deploy this to a JAR file
Step 7: Now Right Click on View/Controller Node and create a Java File �
UserController.java -
package lux.controllers;
import javax.ejb.EJB;
import javax.faces.model.DataModel;
import javax.faces.model.ListDataModel;
import lux.domain.User;
import lux.facade.UserDAO;
public class UserController {
@EJB UserDAO userDao;
private User user;
private DataModel model;
public String createUser() {
this.user = new User();
return "create_new_user";
public String saveUser() {
String r = "success";
try {
userDao.createUser(user);
} catch (Exception e) {
e.printStackTrace();
r = "failed";
return r;
public DataModel getUsers() {
model = new ListDataModel(userDao.getAllUsers());
return model;
public User getUser() {
return user;
public void setUser(User user) {
this.user = user;
Step 8: Configure page flow in faces-config.xml
1. Create the JSP file adduser.jsp by right-clicking View-Controller
node and selecting New > JSP. Use the wizard to create JSF � JSP Page, fill in
File Name adduser.jsp, click Finish. -
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>New user</title>
</head>
<body>
<f:view>
<h:form>
<h:messages/>
<h:panelGrid columns="2">
<h:outputText value="Username"/>
<h:inputText

value="#{user.user.username}"
required="true"/>
<h:outputText value="First name"/>
<h:inputText
id="FirstName"
value="#{user.user.firstName}" />
<h:outputText value="Last name"/>
<h:inputText
id="LastName"
value="#{user.user.lastName}" />
<h:outputText value="Password" />
<h:inputSecret
id="Password"
value="#{user.user.password}"
required="true" />
<h:panelGroup/>
<h:commandButton
action="#{user.saveUser}"
value="Save"/>
</h:panelGrid>
</h:form>
</f:view>
</body>
</html>
2. Repeat the previous step for another JSP file failed.jsp.
3. On failed.jsp add the string
Save failed
Next we configure the page flow.
1. Open faces-config.xml.
2. Create index.jsp -
<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>User Listing</title>
</head>
<body>
<f:view>
<h:form>
<h:outputText value="User Listing"/>
<h:commandLink action="#{user.createUser}" value="Create a user"/>
<h:dataTable value="#{user.user}"
var="dataTableItem" border="1" cellpadding="2" cellspacing="2">
<h:column>
<f:facet name="header">
<h:outputText value="Username"/>
</f:facet>
<h:outputText value="#{dataTableItem.username}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="First name"/>
</f:facet>
<h:outputText value="#{dataTableItem.firstName}" />
</h:column>
<h:column>
<f:facet name="header">
<h:outputText value="Last name"/>
</f:facet>
<h:outputText value="#{dataTableItem.lastName}" />
</h:column>
</h:dataTable>
</h:form>
</f:view>
</body>
</html>
3. Drag an arrow from index.jsp to adduser.jsp and replace the arrow�s label to create_new_user.
4. Repeat the previous step for failed, by dragging and arrow from adduser.jsp to failed.jsp renaming the label to f
ailed
5. Finally repeat the step for adduser.jsp, by dragging from adduser.jsp to index.jsp renaming the label to success.
This creates the following faces-config.xml file �
<?xml version='1.0' encoding='UTF-8'?>
<faces-config>
<managed-bean>
<managed-bean-name>user</managed-bean-name>
<managed-bean-class>lux.controllers.UserController</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
<managed-property>
<property-name>username</property-name>
<value>#{username}</value>
</managed-property>
<managed-property>
<property-name>firstName</property-name>
<value>#{firstName}</value>
</managed-property>
<managed-property>
<property-name>lastName</property-name>
<value>#{lastName}</value>
</managed-property>
<managed-property>
<property-name>password</property-name>
<value>#{password}</value>
</managed-property>
</managed-bean>
<navigation-rule>
<from-view-id>/index.jsp</from-view-id>
<navigation-case>
<from-outcome>create_new_user</from-outcome>
<to-view-id>/adduser.jsp</to-view-id>
</navigation-case>
</navigation-rule>

<navigation-case>
<from-outcome>success</from-outcome>
<to-view-id>/index.jsp</to-view-id>
</navigation-case>
</navigation-rule>
</faces-config>
Step 9: Create a Deployment file in the View-Controller and Deploy this to a WAR file
Step 10: Create a Deployment file in the View-Controller and create an EAR file and add Model�s JAR and View-Controller�s
WAR files to it.
Step 11: Run the JSP Files
SCENARIO END
Now, When I execute Index.jsp, it does not list values from database and when I click on Create User link, it takes me to adduser.jsp page. When I fill values in this page and click Save button, it takes me to Save Failed page and data does not persist to the database.
WHAT IS WRONG OUT HERE ???If you set a breakpoint in your createUser method - does this code get executed?
We have a couple of tutorials that might show you how to do this.

This query does not exist in the database in the system
I have created a query, but when I run it, I receive this error:
You have attempted to open query 0DAT from the Query Designer.
However, this query does not exist in the database in the system to which you have made a connection.
Thanks
Joseiltondear Joseilton,
the variable 0DAT ist not in active version in your system.
Use BC to activate the variable 0DAT from InfoObject 0CALDAY.
or
you have to create it in your system. therefor change the namespye to SAP-namespace (starting with 0). Open one Query in your system via RRMX and select CalenderDay to create a new variable.
name: 0DAT
descrition: current calender day
processed by: SAP EXIT
Characteristic: Calender Day
variable represents: Single Value

Table /xyz/abc does not exist in the database
Hi experienced developers,
I created two transparent tables in customer name space in development system, transport to quality together with program using the tables, everything fine, no errors, no warnings.
Then transported to production. No errors, no warnings. Detailed protocol shows tables have been activated, no errors or warnings.
First try to use the program gives a dump.
line 1191:
""/xyz/abc" is not defined in the ABAP Dictionary as a table, p"
"rojection view, or database view."
Double-click on the table in program code gives a popup information message
Table/xyz/abc does not exist in the
database
After acknowleding the popup, the usual dictionary entry is shown, table is active. Utilities -> database object -> Display leads to an empty screen
Fields of /xyz/abc
Fld name Position Data Type Length Decimals Not null Default
Indexes for /xyz/abcI
Utilities -> runtime object -> Display shows the table name followed by message
There is no active runtime object for ...
prededed by big icon exclamation mark.
We created a new transport with exactly the same result.
Basis people have no idea.
The only thing special (but OK I think) is that the tables have key fields only.
Database is Oracle 11.2.0.2.0, SAP ECC 6.0

Table ZCHECKPICK does not exist in the database
Hi!
I have a table "ZCHECKPICK" no "MANDT - Client".
Then I inserted a field "MANDT - Client" and executed SE14 to "Active and adjust database".
The table is now "does not exist in the database" but the struture is ok.
What do i do to get the table in DataBase again?
<Priority normalized in subject line>
Edited by: Vinod Kumar on Sep 13, 2011 9:32 AMDear Clayton,
you can try a few things
1) generate/activate the table prior to call SE14.
2) after confirming that the table is well generated, go to SE14 and choose "Delete Database Table"
3) then, still on SE14, click on "Activate and Adjust database"
[http://imageshack.us/photo/my-images/607/20110913010743.jpg/]
That should fix it.
