compilation error for EVAL_BODY_AGAIN

[Ritu varada]

I am trying out a custom tag example. I am running tomcat5 andd have the jsp-api.jar in my classpath. I know that is okay because I have been able to execute Simple tags. Anyway, here is the custom tag

package foo;

import javax.servlet.jsp.JspException;
import javax.servlet.jsp.JspWriter;
import javax.servlet.jsp.tagext.TagSupport;
import java.io.IOException;



public class CustomTagTest3 extends TagSupport {

int movieCounter;
String[] movies = {"Amelie","Sandy beaches","Veer zara","SomethingElse"};

public int doStartTag() throws JspException {
movieCounter = 0;

return EVAL_BODY_INCLUDE;
}

public int doAfterBody() throws JspException {

if (movieCounter < movies.length) {
pageContext.setAttribute("movie",movies[movieCounter]);
movieCounter++;
return EVAL_BODY_AGAIN;
}
else {
return SKIP_BODY;
}
}
public int doEndTag() throws JspException {

return EVAL_PAGE;
}
}

I am getting the below compilation error.

C:\HEADFI~1\CustomTagTest3>javac foo\CustomTagTest3.java
foo\CustomTagTest3.java:26: cannot resolve symbol
symbol : variable EVAL_BODY_AGAIN
location: class foo.CustomTagTest3
return EVAL_BODY_AGAIN;
^
1 error


I know that EVAL_BODY_AGAIN is a valid return value for doAfterBody(). What am I missing ?

Actually, I tried that and it still did not work. Anyway, TagSupport should do for doAfterBody() method. Does the class compile for you ? Thanks for your help!

Hi Ritu.
I think its a compiler error...And its occured bcoz u have not imported javax.servlet.jsp.tagext.Tag. all the implicit return types like EVAL_BODY_INCLUDE , etc. are final variables of this interface....Hope this helps.

I have imported the TagSupport class which should be enough. Anyway, I tried importing the Tag interface too. Its still giving me a compiler error. I am so frustated...

I just tried your code and it compiles for me.

Check your classpath again

Hmm..I rearranged some of the jar files in my classpath and the code compiled! Thanks, Ben! Next time, I will just have to make my mind work in more directions than just posting immediately. Thanks for all your help.
