Sorry - the ServletException was: Cannot find bean component in any scope I was doing another experiment attempting to iterate containers and got the messages mixed.

I have print statements in the Action Im stumped? Any Ideas I will try Struts 1.0.2 - Except the examples seem to work :-) Thanks for your help Ray Madigan -----Original Message----- From: Jacob Hookom [mailto:[EMAIL PROTECTED]] Sent: Monday, February 10, 2003 10:24 PM To: 'Struts Users Mailing List' Subject: RE: Newbie Question ArrayList components = (ArrayList) service .gatherAccessory(Bean.getContainer()); session.setAttribute("someKey", components); -or- request.setAttribute("someKey", components); <!-- jsp --> <logic:iterate id="item" name="someKey" scope="session"> //or request scope <bean:write name="item" property="name" /><br /> </logic:iterate> -Jacob | -----Original Message----- | From: Ray Madigan [mailto:[EMAIL PROTECTED]] | Sent: Tuesday, February 11, 2003 12:06 AM | To: Struts Users Mailing List | Subject: Newbie Question | | Greetings: | | I am new to struts, and i have a question that has been giving me fits all | day. | | I have a large application I am attempting to rewrite in struts, with | several hundred jsp's and servlets. It currently runs on Tomcat. I am | using, don't all of you laugh at once, 1.1-b3. | | I haveured out some of how struts works from reading the samples and | groping | throught the code, but i can't seem to figure out how to make | logic:iterate | work. Here are a couple oc code fragments, if someone could point out | where | i'm a bonehead, i would appreciate it. | | In the Action class: | ArrayList components = ( ArrayList ) service.gatherAccessory | Bean.getContainer ( ) ); | // Error checking and logging etc | if ( components != null && components.size ( ) > 0 ) { | System.out.println ( "Nav: Comp: " + components.size ( ) ); | //txSupport component = new txSupport ( ); | //session.setAttribute ( Constants.COMPONENT_KEY, components.get | ( 1 ) ); | //session.setAttribute ( Constants.COMPONENTS_KEY, | components.toArray ( as ) ); | session.setAttribute ( component, components.get ( 0 ) ); | navForm.setComponents ( components ); | } | | I have tried several alternatives as to how to set the id attribute: | - an empty instance of the Bean that is contained in the collection | - the first element in the array | I have tried to set the name property of the iterate to an array | all with different errors. The one that worked the best was when | I pointed the id property of iterate to the first element of the | Collection. Here i simply got the iterator to iterate the first | element. In the Action class I have iterated the Collection and | there are three elements in the list. | | In the jsp: | | <logic:iterate id="component" name="navigateForm" property="components" | > | | <tr> | <td COLSPAN="2"align="left"> | <bean:write name="component" property="support" filter="true"/> | </td> | </tr> | | </logic:iterate> | | The navigateForm has a pair of methods get/setComponents that return the | Collection. If I put a logic:equal and test a member of the iteration it | works in all cases. | | I am very perplexed by this situation and any light shed on the problem | would be appreciated. | | Thanks in advance | Ray Madigan | | | --------------------------------------------------------------------- | To unsubscribe, e-mail: [EMAIL PROTECTED] | For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
