[umar hathab]

Hi friends,
can u post me the jsp code ? I want to see how u r referring the taglib...
Since your taglib-uri is /WEB-INF/classes/js ,
you should have
<%@ taglib uri="/WEB-INF/classes/js" prefix="something" %>
and yr JavaScriptExTag.tld should be under /WEB-INF/

Hope this helps ..
A.Umar

[sim sim]

HI taash,
Try this in your tld.
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE taglib
PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.1//EN"
"http://java.sun.com/j2ee/dtds/web-jsptaglibrary_1._1.dtd" >

Hope this works.
Regards,
Sim Sim.

[Simon Brown]

...and if you're using Tomcat 4, you can use the newer JSP 1.2 DTD (although some of the element names have changed) :

<?xml version="1.0" encoding="ISO-8859-1" ?> 
<!DOCTYPE taglib
  PUBLIC "-//Sun Microsystems, Inc.//DTD JSP Tag Library 1.2//EN"
  "http://java.sun.com/dtd/web-jsptaglibrary_1_2.dtd">
<taglib>
  <tlib-version>1.0</tlib-version>
  <jsp-version>1.2</jsp-version>
  <short-name>JavaScriptExTag</short-name>
  <uri>/WEB-INF/classes/js</uri>
  <description>A simple tag lib</description>
  <tag>
    <name>message</name>
    <tag-class>/JavaScriptExTag</tag-class>
    <description>display alert box</description>
  </tag>
</taglib>

just in case

You'll need to put your tag handler class in a package, and then modify the TLD file appropriately. For example:
<tag-class>myPackage.JavaScriptExTag</tag-class>
(notice also that there is no leading / character)
Cheers
Simon

[taash mg]

hi Simon,
i tried changing the hierarchy
so now it looks like this
this is the hierarchy for my files
/WEB-INF/web.xml
/WEB-INF/JavaScriptExTag.tld
/WEB-INF/classes/sunskriti/JavaScriptExTag.java
/WEB-INF/classes/sunskriti/JavaScriptEx.java
/jsp/JavaScript_Tag.jsp
and in my tld file
i modified it by putting it into a package called sunskriti

 
<short-name>js</short-name>
<uri>/WEB-INF/classes/js</uri>
<description>A simple tag lib</description>
<tag>
<name>message</name>
<tag-class>sunskriti.JavaScriptExTag</tag-class>
<description>display alert box</description>

i also modified both my java files and added package statements but still am not getting result

at java.lang.Thread.run(Thread.java:536)

[Simon Brown]

Have you placed the compiled classes under /WEB-INF/classes too? That is :
/WEB-INF/classes/sunskriti/JavaScriptExTag.class
/WEB-INF/classes/sunskriti/JavaScriptEx.class
Simon

[taash mg]

hi Simon
thanks for reminding me i nearly forgot that i had to compile these classes, silly of me any ways i did that but the class JavaScriptExTag really doesn't compile. it gives me many error
this is the code

  
package sunskriti;
import java.io.*;
import java.io.IOException.*;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
public class JavaScriptExTag extends BodyTagSupport 
{

public int doEndTag() throws JspTagException
{
String ls_alert = " ";
try{
BodyContent lbc_bodycurrent = getBodyContent();
if(lbc_bodycurrent!=null)
{
String ls_message=lbc_bodycurrent.getString();
JavaScriptEx JS = new JavaScriptEx();
ls_alert=JS.alert(ls_message.trim());
}
pageContext.getOut().write(ls_alert);
}
catch(IOException e)
{
throw new JspTagException("Error:"+e.toString());
}
return EVAL_PAGE;
}
}

it actaully doesn't recognise the Jsp Exceptions. wonder why?? i think we have imported the proper classes
is this Exception custom made in the wrox package?
Thanks again for all the help

[Simon Brown]

If you're using Tomcat 4, you need to put the servlet.jar file (from TOMCAT_HOME/common/lib) in your CLASSPATH.

Hi
But then if i quit i wouldn't learn so somebody please help me out here

thanks

[sim sim]

Hi Taash,
I suggest you check your classpath once again, I have tried to compile your code and I got only one exception, cannot find,
JavaScriptEx JS = new JavaScriptEx();
I have commented the following lines
//JavaScriptEx JS = new JavaScriptEx();
//ls_alert=JS.alert(ls_message.trim());
and it compiled in a jiffy.
Pl check ur classpath for
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
Regards,
Sim Sim

[amit sanghai]

Hi Taash,
Please compile JavaScriptEx.java first and include that into ur classpath as well. Then compile JavaScriptExTag.java

[taash mg]

Hi
sim sim
I already have tools.jar in my classpath? Do i need to put jasper.jar too? as i have about 11 errors when i try to compile JavaScriptExTag.java and mostly regarding JspException and the other stuff.
this is a part of it

amit
i have already complied JavaScriptEx.java before doing this and both of these files are in the same directory.. but i am still not getting through this code
thanks

[taash mg]

hi sim sim
