RE: Problem using session var
Rafael,
Your try/catch lists YOUR setter as:
tipocambio.setstrValor()
This suggests you make your getter tipocambio.getstrValor(). Unfortunately,
bean:write capitalizes the first letter of the property so bean:write is
trying to invoke 1stTipoCambio.getStrValor(), not your
1stTipoCambio.getstrValor() (Note the Str versus str in the setter which
you probably used the same way in your getter) method as suggested by your
example code.
Regards,
David

Subject: Problem using session var
Hi folks. I have a problem using session variables, I hope u can help me.
In my jsp:
bean:write name=lstTipoCambio property=strValor /
In my action:
if (session.getAttribute(lstTipoCambio)==null)
session.setAttribute(lstTipoCambio,articuloDAO.getTipoCambio());
In my DAO:
getTipoCambio returns a Collection, a set of TipoCambio objects.
try {
StringBuffer sbSelect = new StringBuffer();
sbSelect.append(select TCA_VALOR_F );
sbSelect.append(from SCR_TIPOCAMBIO_TCA);
stmtSelect = conn.prepareStatement(sbSelect.toString());
rs = stmtSelect.executeQuery();
while (rs.next()) {
TipoCambio tipocambio = new TipoCambioImpl();
tipocambio.setstrValor(rs.getString(TCA_VALOR_F));
collResultado.add(tipocambio);
}
}
Off course TipoCambio is a bean with getters and setters method for
each attribute.
And the error:
javax.servlet.ServletException: No getter method for property
strValor of bean lstTipoCambio

Re: Problem using session var
I didn't know about capitalization of bean:write. So, how can i know in order to print some data in my jsp?. using session vars... Using JSTL?.. I don't know. -- Rafael Taboada - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Problem using session var
This has nothing to do with sessions - it is just standard bean naming, and AFAIK, all jsp tags will stick to this. The methods getXxx and setXxx create a property named xxx. One more naming issue to watch out for is this one: The methods getXName and setXName create a property named XName, not xName - if the first 2 letters are uppercase, the name is taken exactly. If you cannot rename the methods, then I think you are stuck with using a scriptlet. :-( Larry On 5/11/05, Rafael Taboada [EMAIL PROTECTED] wrote: I didn't know about capitalization of bean:write.

Re: Problem using session var
I renamed my methods but nothing happened. My new getters and setters: getStrValor() setStrValor() But it's still the same error. But I did this: logic:iterate id=lista name=lstTipoCambio bean:write name=lista property=strValor / /logic:iterate And it worked Do u know why? Because lstTipoCambio is a collection object???. And why don't work renaming my methods like Larry said??? -- Rafael Taboada - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Problem using session var
Rafael, Are you sure you used the logic:iterate with the old method signatures and not the new case sensitive getters and setters?

Re: Problem using session var
Yes, I used logic:iterate with getstrValor and setstrValor and it worked fine.. But I tried with logic:iterate and getStrValor and setStrValor and it worked too... So, what's the problem???... Is my bean:write name=lstTipoCambio property=strValor / Has it to be inside a iteration method??? Because lstTipoCambio is a collection Id tried withouth logic:iterate and getStrValor and setStrValor but it didn't worked... -- Rafael Taboada - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: Problem using session var
My bad... I cleaned and rebuilt and It works without logic:iterate and getStrValor and setStrValor and strValor attribute. :) But. Why does it work using logic:iterate and getstrValor and setstrValor?

Re: Problem using session var
Hi! bean write tag just takes a bean under name key form the scope where you indicates with scope or with findAttrinute searching in every scopes if you omit the scope attribute. Once the bean is found, the tag, takes the value of the property attribute as String and -first replace the first letter of this string by the same letter capitalized, -seccond concats this result to the String get -finally the result ys a String with the form getXayz if the ptoprty value of the tag were xayz So the tag has two elements, a bean, and the name of a method, a getter... Via reflection api the getter is executed over the bean, and the result is printed in the screen... all this work is done with common bean utils component so i recommend you visit the page finally the tag will be trying to execute the method getStrValue, on a Set, and this getter is never found so you get an exception i wish it hepls...
