Defining dynamic default value for a cookie
Hello!
I'm trying to define a default value in the jsp for a cookie, but I don't know
how to do it :-(.
I've go the following piece of code:
...
<bean:write name="Integrationmenuform" property="pname"/>
<bean:cookie id="cpname" name="CookieCname" value=""/>
...
I would like to have the output from the bean:write - tag as input for the value
in the bean::cookie - tag:
<bean:cookie id="cpname" name="CookieCname" value='<bean:write
name="Integrationmenuform" property="pname"/>'/> does not work (the bean:write -
tag without the cookie - tag works fine).
Which way must the bean:cookie - tag be written to get a dynamic default value?
Thanks for any hint,
kind regards,
Andreas Hartmann

Yes, it's in the request scope. Should work. I'll test it tomorrow. It's
really a pity that the struts taglibs don't work in any case. Will there
be a solution in the future :-)?

Re: Defining dynamic default value for a cookie [*]

Hello Puneet!
I could solve my problem now on my own :-). I addressed the class directly in
the jsp-file:
<bean:cookie id="cpname" name="CookieCname"
value='<%=((de.fiducia.integration.Integrationmenuform)request.getAttribute("Integrationmenuform")).getPname()%>'/>
<bean:cookie id="cvrm" name="CookieCvrm"
value='<%=((de.fiducia.integration.Integrationmenuform)request.getAttribute("Integrationmenuform")).getVrm()%>'/>
The created symlinks I mentioned in the other post are not needed any more.
Kind regards,
Andreas Hartmann

Hello Puneet,
I tried your solution, but I'm getting now another error:
Generated servlet error:
Integrationmenuform cannot be resolved to a type
I wrote the following in the jsp:
<bean:cookie id="cpname" name="CookieCname"
value='<%=((Integrationmenuform)request.getSession().getAttribute("Integrationmenuform")).getPname()%>'/>
<bean:cookie id="cvrm" name="CookieCvrm"
value='<%=((Integrationmenuform)request.getSession().getAttribute("Integrationmenuform")).getVrm()%>'/>
My web.xml from conf-dir with the init-params:
<servlet>
<servlet-name>jsp</servlet-name>
<servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>
<init-param>
<param-name>fork</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>xpoweredBy</param-name>
<param-value>false</param-value>
</init-param>
<load-on-startup>3</load-on-startup>
</servlet>
I straced the java-container and detected, that there is an attempt to load
Integrationmenuform at another place. Therefore, I created some symlinks in
order to give the java container the requested class. I set the created
directories to the tomcat user. This is, what I can see after I created the
symlinks:
....
5880 stat("/opt/apache-tomcat-5.5.17
/webapps/integration_portalmanagement/WEB-INF/classes/org/apache/jsp/pages/Integrationmenuform.class",
{st_mode=S_IFREG|0644, st_size=9084, ...}) = 0
5880 access("/opt/apache-tomcat-5.5.17
/webapps/integration_portalmanagement/WEB-INF/classes/org/apache/jsp/pages/Integrationmenuform.class",
R_OK) = 0
5880 stat("/home/tomcat/org/apache/jsp/pages/Integrationmenuform.class",
0x412501b0) = -1 ENOENT (No such file or directory)
5880 stat("/opt/apache-tomcat-5.5.17
/common/classes/org/apache/jsp/pages/Integrationmenuform.class", 0x41250210) =
-1 ENOENT (No such file or directory)
...
I can't find any open ... . I don't know, why struts doesn't want to load it. Do
you have an idea?
Thanks for your help,
kind regards,
Andreas Hartmann

Try
<bean:cookie id="cpname" name="CookieCname"
value='<%=((YourType)request.getAttribute("Integrationmenuform")).getPname()%>'
/>
This is assuming your bean is in request scope, make appropriate changes
incase the bean is in session scope.
Dont think this solution is pleasing to the eye....:-)
