Can you post your jsp and associated files here???

[Christophe Verré]

Make sure the DateTimeTag1 class (your class ?) is in the path. Probably under WEB-INF/classes or WEB-INF/lib if it's in a JAR file.

Here are diffrent file for tag.please check it.

DateTimeTag.java file in simpletag\WEB-INF\classes directory

import java.io.IOException;
import java.text.DateFormat;
import java.util.Date;
import javax.servlet.jsp.JspException;
import javax.servlet.jsp.tagext.SimpleTagSupport;
public class DateTimeTag extends SimpleTagSupport {
public void doTag() throws JspException, IOException {
DateFormat df = DateFormat.getDateTimeInstance(DateFormat.MEDIUM, DateFormat.MEDIUM);
getJspContext().getOut().write(df.format(new Date()));
}
}

Hello Gajanan,

Just want to clarify that you have to keep compiled version of java Soruce file, .class file in WEB-INF/Classes folder. You have mentioned that DateTimeTag.java file is in simpletag\WEB-INF\classes directory. If not already then please compile this DateTimeTag.java and keep DateTimeTag.class file in simpletag\WEB-INF\classes directory.

Thanks

Hello dhananjay,
Thanks for reply.I compiled java file and kept in \WEB-INF\classes.
All files kept in all specified location.There is no
compile error in any file. These same problem occurs
for other application.

[Christophe Verré]

First,
TLD: <uri>http://www.apress.com/projsp/ch06</uri>
JSP: uri="/WEB-INF/tlds/ch06.tld"
Why are URI different ?

Second,
you really should put your classes into packages.
