Scripting variables declared AT_END do not work when tag implements TryCatchFinally.
Summary: Scripting variables declared AT_END do not work when tag
implements TryCatchFinally.
Product: Tomcat 4
Version: 4.1.12
Platform: PC
OS/Version: Windows NT/2K
Status: NEW
Severity: Critical
Priority: Other
Component: Jasper 2
AssignedTo: tomcat-dev@jakarta.apache.org
ReportedBy: sami.pajunen@almare.com
Scripting variables declared within tag implementing TryCatchFinally interface
are positioned inside try block in the generated code thus hiding their
visibility to rest of the page.
Example (foo.tld not included):
test.jsp:
<%@taglib uri="foo" prefix="foo" %>
<foo:foo>
</foo:foo>
<%= test %>
FooTag.java:
package foo;
import javax.servlet.jsp.tagext.*;
public class FooTag extends BodyTagSupport implements TryCatchFinally {
public int doEndTag() {
pageContext.setAttribute("test", "testValue");
return EVAL_PAGE;
}
public void doCatch(Throwable exc) {
}
public void doFinally() {
}
}
FooTEI.java:
package foo;
import javax.servlet.jsp.tagext.*;
public class FooTEI extends TagExtraInfo {
private static final String DEFAULT_VAR_NAME = "test";
public VariableInfo[] getVariableInfo(TagData tagData) {
String varName = null;
VariableInfo varInfo = new VariableInfo(
(varName==null?DEFAULT_VAR_NAME:varName),
"java.lang.String", true,
VariableInfo.AT_END);
return new VariableInfo[] {varInfo};
}
}
Resulting compile exception:
org.apache.jasper.JasperException: Unable to compile class for JSP
An error occurred at line: 5 in the jsp file: /test.jsp
