Hi, i am just trying a simple example of a custom tag. but it does not run and gives root cause as INVALID PUBLIC ID- .... can anybody help me to learn this properly heres my web.xml and the error--- web.xml
hi i got that error,my tld file had a different public definition, so i have corrected that but i still can't work this out as now Tomcat has proceded to say that
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

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

hi just in case this is the hierarchy for my files /WEB-INF/web.xml /WEB-INF/JavaScriptExTag.tld /WEB-INF/classes/JavaScriptExTag.java /WEB-INF/classes/JavaScriptEx.java /jsp/JavaScript_Tag.jsp
and a part of the root cause for error
Thanks Taash

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

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

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

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
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

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

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

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
