Am I missing anything here? Any suggestions please. Thank you. Bob. A snippet from my ApplicationResources.properties file : . . books.publisher.heading= . . A snippet from my JSP : . . . .

Re: character entities conversion
The output rendered perfectly when the filter attrib. was set to 'false'! Thanks once again James. Bob.
Re: character entities conversion
Hi James, Thanks for the link to the docs. I got the ff. from the docs a short while ago : "filter If this attribute is set to true, the rendered property value will be filtered for characters that are sensitive in HTML, and any such characters will be replaced by their entity equivalents." I have set the filter attrib. to 'true' , however, my output is still the same. I do still get: "...you use UNIX, you probably use csh to type commands even if you've never heard of it. It's the standard shell (command line) on most UNIX systems..." instead of : "you use UNIX, you probably use csh to type commands even if you've never heard of it. It's the standard shell (command line) on most UNIX systems" What could be missing here?
Re: character entities conversion
Hi James, I would very much like to. Please direct me to where I can get the needed info. in the docs. I have never had to use the filter attrib. in a tag. Any suggestions are welcome.

I am using the tag. Are suggesting that I write something like : ?
Re: Best practices - help
Thank you all for your useful suggestions. I have gotten it up working now with only something left which I wish it were not there: I have this '../myaction.do' trailling at the end of the URL which I wish it were not there. Preferable would have been /myaction.do after being called in the < global-forwards> to call my action servlet, will re-direct or forward to /MyLayer.jsp. I know that it can be done , but I don't where/how to fix that in my struts-config.xml file. Any ideas ? Thanks. Bob
character entities conversion
Has anyone any idea how to get character entities which are delivered to a Java Bean from a database converted or rendered to its normal characters in a JSP layer? E.g.. I have a database which is delivering "&","'" etc. instead of the characters "&", "'" etc. in my JSP presentation layer. I have set <%@ page contentType="text/html;charset=UTF-8" language="java"%> in my JSPs but to no-avail. I am getting an output such as : "...you use UNIX, you probably use csh to type commands even if you've never heard of it. It's the standard shell (command line) on most UNIX systems..." instead of : "you use UNIX, you probably use csh to type commands even if you've never heard of it. It's the standard shell (command line) on most UNIX systems" Thanks. Bob

Is there a way to populate a bean on a Server's (I'm using Tomcat) start up in Struts? I have a Java bean, say X, which is called and a populated in an Action Servlet, say myAction. Whenever I start my application and call a JSP layer say, MyLayer.jsp, which is supposed to iterate this bean using , I get the exception: org.apache.jasper.JasperException: Cannot find bean X in scope session - - However, this exception disappears when I first call the Action Servlet directly with a call such as http://localhost/myaction.do , followed by a http://localhost/MyLayer.jsp call. Apparently the bean has nothing to show when I first call MyLayer.jsp. Can someone suggest a better approach? Thanks Bob Ps.: the bean, X, get its values from a database. my struts-config.xml snippet : --- -- --- ---
ResultSet get closed before connection closes - Help!
I am using a GenericDatasource to establish a connection to a mysql database.
The connection get established all right, but when I try to walk the
ResultSet, I do get an SQLException which interprets as the ResultSet having been
closed. Can someone please explain why a ResultSet object cannot be iterated or
walked through even before I close the connection to the database?
Exception(java.sql.SQLException: Operation not allowed after ResultSet
closed) occurs when I try to call the method next() of java.sql.ResultSet
A snippet of the code in my Action class read as follows:
private ResultSet myResultSet;

HttpSession session = request.getSession();
try {
dataSource = getDataSource(request);
myConnection = dataSource.getConnection();
Statement stmt = myConnection.createStatement();
myResultSet = stmt.executeQuery("SELECT * FROM my_table ORDER BY
id ;");
this.setResultSet(myResultSet);
} catch (SQLException sqle) {
}
ArrayList bookArrayList = new ArrayList();
try {
ResultSet res = this.getResultSet();
while (res.next()) {
Book book = new Book();
book.setEnglishISBN(res.getString("isbn"));
book.setEnglishAUTHOR(res.getString("author"));
bookArrayList.add(book);
}
} catch (SQLException ignored) {
}
session.setAttribute("Books", bookArrayList);
