Populating an HTML-Form
Hello, at a jsp-Page I want to populate the a form, the required data are in a bean. How do I populate it? I´m new at the struts framework and I didn´t find documentation for this. The Struts-Example-Webapplication is nonapparent for me. For Detail: The user has see a list as an dynamic html-Table with userdata, every row has a link to edit this userdata. When he clicks on it a new form has to appear with the userdata, now he can edit it and make an database-update. My Problem ist to fill the form with the data, I would be glad if you can help me with the necessary Struts-tags, Regards Maik Mrazovic T - S y s t e m s debis Systemhaus MEB GmbHBusiness Center Sales & eBusiness, R&D/VN Erich-Herion Str. 13 70736 Fellbach (Phone) +49 711 17-40549(Mobile) +49 170 832-5616(email) [EMAIL PROTECTED]Internet: http://www.t-systems.de
Re: Problems with Database because of Datasource-Config of Struts!
thanks,
but it´s indifferent if Autocommit is "false" or
"true" it does not work with both options!
Database is IBM DB2 7, but the reason for my
problem ist the connection-object from the datasource-config.
regards,
Maik

Problems with Database because of Datasource-Config of
Struts!
Hello,
all parameters for a database of a
webapplication are configured well in struts-config.xml. There are no
problems when I make a SELECT, but INSERT, DELETE or UPDATE don´t work, I
don´t know why exactly.
The problem is the Connection-Object! If you
use Struts-config.xml you get the Connection Object with
java.sql.Connection myConnection =
null;
try
{
javax.sql.DataSource dataSource =
this.getServlet().findDataSource(null);
if (dataSource
!= null)
{
myConnection = dataSource.getConnection();
...
and so on.
When I aks the Object of Classname
(myConnection.getClassName()) the name is
apache.struts.util.GenericConnection.
With this Connectionobject are INSERT etc
impossible, but why?!
If my connection-Object is developed like
this:
try{
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
Connection c = DriverManager.getConnection("jdbc:ODBC:V68CIMPA",
"j68cimpa",
"cimpa");
INSERTS etc
works fine!!! But that´s stupid, because I must have in every classes the
database-parameter, with struts-config.xml not, it comes from
.findDataSource(), in other words its better to configure the
webapplication!
I hope you can help me,
best regards,
Maik Mrazovic

Re: Access a relational database, problem
Problem solved, it works now. I forgot a xml-end tag, that was all! But it´s strange, that Tomcat didn´t made an xml-input-error. Regards, Maik Mrazovic
Access a relational database, problem
I want to access relational database via Struts and JDBC. At Struts-User-Guide, 2.6, are instructions for creating the data-source - section at struts-config.xml and a example perform-Method for access. But it does not work, I can make a connect manual, but not with the struts data-source configuration: javax.sql.DataSource dataSource = servlet.findDataSource(null); dataSource is null after this row, so it didn´t find a datasource, although the data-source configuration is correct?! I would be glad if you can help me!

Re: Servlet-Error, "Unable to open taglibrary /WEB-INF/struts-bean.tld ..."
Thanks, yes, it was already in web.xml, but the name of directory was "WEB-INF" (capital letters), the directory from Windows-NT was "web-inf", that was the reason! Does only Tomcat (I use 3.2.2) distinguish the letters, or is it at Websphere e.g. the same?

Re: Servlet Error 500, Missing message for key index.title
Hi Klaus, thanks for your help, but as I already wrote it´s always the first key of the propertiesfile, in my case the "index.title" - key. I assume Struts don´t find any keys, and I dont know why. And in fact that I tried to start several war files, e.g. the struts-example (!) it has to work, but it does not! Perhaps a problem with Tomcat?!

I´ve installed struts, under Tomcat 3.2. None Webapplication will run which uses ApplicationResources.properties, when I start an index.jsp there comes always the error javax.servlet.ServletException: Missing message for key index.title but i don´t know why?!!? The File is in correct folder, I´ve tried to start several webapplications which was deployed as war-Files, no one works, always this Error, that makes me crazy! I use Struts 1.0 b3, I hope somebody can help me!
