tomcat 6.0.18 issue with my customer Tag class
Hi, everyone,
I run the tomcat 6.0.18 on my ubuntu 8.04.2, the jdk version is 1.6.0_07
I configure the localhost 's ROOT to my home directory /home/ghw/myjava
the configuration file like this:
<?xml version='1.0' encoding='utf-8'?>
<Server port="8005" shutdown="SHUTDOWN">
<Listener className="org.apache.catalina.core.AprLifecycleListener"
SSLEngine="on" />
<Listener className="org.apache.catalina.core.JasperListener" />
<Listener className="org.apache.catalina.mbeans.ServerLifecycleListener"
/>
<Listener
className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
<GlobalNamingResources>
<Resource name="UserDatabase" auth="Container"
type="org.apache.catalina.UserDatabase"
description="User database that can be updated and saved"
factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
pathname="conf/tomcat-users.xml" />
</GlobalNamingResources>
<Service name="Catalina">
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
<Engine name="Catalina" defaultHost="localhost">
<Realm className="org.apache.catalina.realm.UserDatabaseRealm"
resourceName="UserDatabase"/>
<Host name="localhost" appBase="webapps"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
</Host>
</Engine>
</Service>
</Server>
and I created the directory understand CATALINE_HOME/conf/Catalina/localhost
and create a ROOT.xml in there
like this:
<?xml version="1.0" encoding="utf-8"?>
<Context path="" docBase="/home/ghw/myjava" debug="9" reloadable="9" >
</Context>
when write a test index.jsp in /home/ghw/myjava, it works.
and when I try to write a Tag class in there, it will be report Error:
*type* Exception report
*message*
*description* *The server encountered an internal error () that prevented it
from fulfilling this request.*
*exception*

and the Tag class like this:
import java.io.IOException;
import javax.servlet.jsp.*;
import javax.servlet.jsp.tagext.*;
public class JavaScriptExampleTag extends BodyTagSupport {
public int doEndTag() throws JspTagException {
String ls_alert = "";

if ( lbc_bodycurrent != null ) {
String ls_message = lbc_bodycurrent.getString();
JavaScriptExample JS = new JavaScriptExample();
ls_alert = JS.alert(ls_message.trim());
}
pageContext.getOut().write(ls_alert);
} catch ( IOException e ) {
throw new JspTagException("Error " + e.toString());
}
return EVAL_PAGE;
}
}
and the Bean class is like this:
import java.io.Serializable;
public class JavaScriptExample implements Serializable {
public JavaScriptExample() {
}
public String alert(Object aobj_data) {
return( start_script + " alert(\" " +
aobj_data.toString() + "\");" +
end_script );
}
//private area
private String start_script = "<script language=\"javascript\">";
private String end_script = "</script>";
}
anyone can help me on this?
thanks very much

Posted by Ron McNulty <rm...@xtra.co.nz>.
Hi Mike
Your tag syntax is a bit unusual. I would have expected
<my:message msg="This is a simple java alert message"/>
Then you put a variable msg in your tag class (with a getter & setter), and
the JSP runtime will populate it for you.
Regards
Ron

RE: tomcat 6.0.18 issue with my customer Tag class
Posted by Martin Gainty <mg...@hotmail.com>.
<!-- start of taglib declaration my is the reference to the taglib which the jsp uses to reference JavaScriptExampleTag-->
<tag>
<name>my</name>
<tag-class>JavaScriptExampleTag</tag-class>
<info>Display Alert Box</info>
<attribute>
<name>message</name>
<required>true</required>
<description><![CDATA[Put some message to echo here]]></description>
</attribute>
<attribute>
<name>id</name>
<required>false</required>
<rtexprvalue>false</rtexprvalue>
<description><![CDATA[id for referencing element. For UI and form tags it will be used as HTML id attribute]]></description>
</attribute>
<attribute>
<attribute>
<name>name</name>
<required>true</required>
<rtexprvalue>false</rtexprvalue>
<description><![CDATA[..Name ..]]></description>
</attribute>
<attribute>
......
</tag>
<!-- at start of jsp put all of your taglib declarations so the prefix my associates my to the JavaScriptExampleTag.tld such as what you see below-->
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<%@ taglib uri="/WEB-INF/tld/JavaScriptExampleTag.tld" prefix="my" name="my"%>
i didnt see the 'message' attribute in your BodyTagSupports declared variables or an accessor e.g.
public class JavaScriptExampleTag extends BodyTagSupport {
........
//String storage allocation for message
public String message;
//mutator
public void setMessage(String message) {
this.message = message;
}
//accessor
public void getMessage() {
return this.message;
}
.......
}

implement pidster's advice for everything else..

Put your tag class in a package, and make sure the tag class is in the
correct folder like so:
myapp/index.jsp
myapp/WEB-INF/classes/com/myapp/YourTag.class
myapp/WEB-INF/tld/YourTag.tld
Adjust the tag class definition in the the TLD accordingly.
