My web application don't want to connect to SQLServer database.
Maybe the problem come to JDBC drivers.
That is TomCat error :
java.lang.RuntimeException: Unable to create connection 'Connection1' to the database.
com.codecharge.db.PoolJDBCConnection.getConnection(PoolJDBCConnection.java:23)
com.codecharge.db.JDBCConnection.<init>(JDBCConnection.java:99)
com.codecharge.db.PoolJDBCConnection.<init>(PoolJDBCConnection.java:15)
I have JDBC/SqlServer driver, but I don't know where I must put it and if it was correctly declared in CodeCharge Studio.
How can I do ?

First of all Which DB do you use?
Did you set DB settings for this connection?
ProjectSettings->Server/Script->Connections->Connection1 (dbl click at the connections list)->Server(it's tab). Here is many fields:
MUST SET: Date Base, JDBC Driver, DataBaseUrl.
And if need: name, password, and date/time/boolean formats.
Did you place JDBC Drivers jar(s) to server (tomcat) classpath or specify path to it is system classpath ? If not, do it.

Most easy way is :
to copy
<JDBC Driver jar(s)> to <TOMCAT_HOME>/common/lib/.
This jar(s) will be available to all projects in this instance of Tomcat.
Is it good or bad is depends from current situation.
just interest : is it your firs java web project?

In web yes, but I did a java project with a SQL connexion which works very well.

Ok. So you must know that main stream in java programming with DB is using JDBC.
And must know all needed parameters for it.
BTW you don't answer which DB du you use?

Actually I have a problem too with JDBC connection... but it is different...
When I execute my page, it show the progress bar, etc... as if it is working on it but the problem is that the server stop responding...
I'm working with an Access Database and here's my code :
if (e.getPage().getParameter("edit")!=null){
JDBCConnection conn = JDBCConnectionFactory.getJDBCConnection("Connection1");
String sql = "UPDATE [m 4 nomenclature] SET [libellé identification]="+e.getPage().getParameter("edit").toString()+
" WHERE [cd mat nm]="+
DBTools.convertToString( DBTools.dLookUp("[cd mat nm]", "[m 4 nomenclature]", "[libellé identification]like'"+
e.getPage().getParameter("old").toString()+"%'", "Connection1"), "Connection1", e.getPage().getCCSLocale());
System.out.println("************************ "+sql);
conn.executeUpdate(sql);
conn.closeConnection();
}
Thanks for your help...

1.
Which event did you use?
Take connections from JDBCConnectionFactory is not the best way.
If you do it in BeforeBuildXXX, BeforeExecuteXXX or afterExecuteXXX, you can get connection from command.
I.E. e.getCommand().getConnection().
2.
ThereIs class DBTools it's helper wor working with DB.
Perhaps it's contain neede methods.
For more detail help how exception stackTrace.

I was doing it on BeforeShow Event of the Page but as you told me I tried to do it on Before Build Select and Before Execute Select Event of the Table and changing the first line of my code by :
JDBCConnection conn = e.getCommand().getJdbcConnection();
But it doesn't change a lot... The server still stop responding...

If you use
JDBCConnection conn = e.getCommand().getJdbcConnection();
in the end you didn't need close Connection, if you close Connection your page didn't work.
conn.closeConnection();
Take this off. Codecharge will close your connection.

If you get off all your block code, it works?
Maybe wasn't deadlock?

Yes it work, that's what I do to continue working on something else...
Actually the deadlock is at the first line of my code...
In the server console I can see that it shows all the component of my page and it stop on the component where I've put the code...

Deadlock I am meaning, in database. You wanna update a table and want to select it.

Ah ok no, the DlookUp clause work well... I already tested it...
I tried to use this code :
java.sql.Connection con = null;
java.sql.PreparedStatement pstmt = null;
try {
con = java.sql.DriverManager.getConnection("jdbc:default:connection");
String edit = e.getPage().getParameter("edit").toString();
String matnm = DBTools.convertToString( DBTools.dLookUp("[cd mat nm]", "[m 4 nomenclature]",
"[libellé identification]like'"+e.getPage().getParameter("old").toString()+
"%'", "Connection1"), "Connection1", e.getPage().getCCSLocale());
pstmt = con.prepareStatement("UPDATE [m 4 nomenclature] SET [libellé identification] = "
+edit+"[cd mat nm] = "+matnm);
pstmt.executeUpdate();
}catch(Exception x){
System.out.println("Une exception s'est produite !" + x.getMessage());
System.out.println("Affichage de la pile :\n"); x.printStackTrace();
}finally{ if(pstmt!=null){ try{pstmt.close();}catch(java.sql.SQLException ex){ex.printStackTrace();} } }
