Compiling error

[Former Member]

Hi all,

I need to compile using command line the HelloWorldSimpleTag.java:

<i>package jsp2.examples.simpletag;

import javax.servlet.jsp.JspException;

import javax.servlet.jsp.tagext.SimpleTagSupport;

import java.io.IOException;

public class HelloWorldSimpleTag extends SimpleTagSupport {

public void doTag() throws JspException, IOException {

getJspContext().getOut().write( "Hello, world!" );

}

}</i>

I use the follow command in order to compile:

<i>javac "D:\Program Files\Apache Software Foundation\Tomcat 5.5\webapps\jsp-examples\WEB-INF\classes\jsp2\examples\<b>simpletag</b>\HelloWorldSimpleTag.java"</i>

In the <b>simpletag</b> folder I inserted the javax.servlet.jsp.jar library.

But I have compiling error on: <b>package javax.servlet.jsp.jar does not exist!!!!</b>

What I wrong??? Thanks.

Jack,

Strange!!! Thanks,

The default class path is the current directory. Setting the CLASSPATH variable or using the -classpath command-line option overrides that default, so if you want to include the current directory in the search path, you must include "." in the new settings

Hope this helps,

Before you compile the java class, put the servlet jar in your classpath. Since you are compiling in commandline you need to set the classpath like this

set classpath="<directory where ur servlet jar resides>;<other jar files>;;;;;;"

Are you sure it isn't supposed to be:

import javax.servlet.JspException;

import javax.servlet.tagext.SimpleTagSupport;

(I don't have access to the libs at the moment to double check the names.)

If you are using <b>NWDS / Eclipse</b>:

Right click on project > Java Build path > Libraries tab > Add External Jars and choose the path where your javax.servlet.jsp.jar lies.

<b>Else</b>, in Windows Environment variable, Classpath variable value enter the path to javax.servlet.jsp.jar. For example: the Classpath would look like this:

<b>C:\Jar\javax.servlet.jsp.jar;.;</b>

Hi,

Try,

1. adding servlet-api.jar in the build path (It should be available under commons/lib directory).

2. adding jsp-api.jar in the build path

3. set system variables accordingly.
