Hi all,
I'm working with Struts 1.1.
When open a JSP page in a popup window with JavaScript, the Session
attributes are lost.
I make a little example:
The test1.jsp put one attribute ("test1") in Session and invoke
test2.jsp in two ways:
a) When submit the form, a forward is defined to return test2.jsp
b) Using a JavaScript function
Test2.jsp only must check that the attribute "test1" exists and
display it:
That is TEST1.JSP
<SCRIPT language="javascript">
� � � � function openwindow(){
� � � � � � � � aBase='<html:rewrite
page="/test2.jsp" />';
� � � � � � � � window.open(aBase, "test2",
"200", "200");
� � � � }
</SCRIPT>
<TITLE>TEST1</TITLE>
<% request.getSession().setAttribute("test1", "hola"); %>
</HEAD>
<BODY>
� � � � <html:form action="/test1Action">
� � � � � � � � <html:text property = "texto"/>
� � � � � � � � <html:submit value="test2"/><br>
� � � � </html:form>
� � � � <a href='javascript:openwindow()'>test2</a>
</BODY>
That is TEST2.JSP
� � � � <BODY>
� � � � � �<logic:present name="test1">
� � � � � � � session.test1:
<bean:write name="test1" scope="session" /><br>
� � � � � �</logic:present>
� � � � </BODY>
That is the piece of struts-config.xml concerned (test1Action do
nothing but returns the addecuate forward ).
� � � � <action-mappings>
� � � � � � �<action
� � � � � � � � � name="test1"
� � � � � � � � � path="/test1Action"
� � � � � � � � � scope="request"
� � � � � � � � � type="test_struts.forms.test1Action">
� � � � � � <forward
name="success"
path="/test2.jsp" />
� � � � � � �</action>
� � � � </action-mappings>
And that is the result:
If test2.jsp is invoked via the Submit button, it is open in the same
browser window and display:
� � � � session.test1: hola
If test2.jsp is invoked via the link, nothing is displayed.
I'm looking in Google and it seems that the session ID (jsession) is
lost.
To avoid that I tried to change the JavaScript code using the next:
� � �<% String url =response.encodeURL("test2.jsp"); %>
� � �window.open( <%=url%>,"TEST", "200", "200");
but with the same results.
My questions are:
How can I open a popup window without losing session?
Is there another way to do that using Struts tags?.
Thanks in advance and excuses for my English.
Regards.
