Help! Iterating through nested hashmap and setting properties
Hi all I have a problem with setting the values on a hierarchy of nested properties. I have an ActionForm which has a property A of type HashMap. A is keyed on Strings, and each value of A is a Collection (ArrayList). This collection contains objects of type B. I am trying to iterate through the keys A, and for each key, iterate through the corresponding value (which is an ArrayList of B objects). The I want to display a property of B and let the user change it. I am able to display the properties of object B on the screen. However, for some reason the tag doesn't work - the textbox is there, but the input does not populate the form. The following is what I am trying to do. The problem is that when I enter a new value for foo, nothing happens; the value of the nested property is not set. Is it possible to iterate through a HashMap, and let the user update its values? I am quite new to Struts, and urgently need this to work, but no luck. Any help will be really appreciated!

Repost: Iterate through nested Map and set values
Hi all I have a problem with setting the values on a hierarchy of nested properties. I have an ActionForm which has a property A of type HashMap. A is keyed on Strings, and each value of A is a Collection (ArrayList). This collection contains objects of type B. I am trying to iterate through the keys A, and for each key, iterate through the corresponding value (which is an ArrayList of B objects). The I want to display a property of B and let the user change it. I am able to display the properties of object B on the screen. However, for some reason the tag doesn't work - the textbox is there, but the input does not populate the form. The following is what I am trying to do. The problem is that when I enter a new value for foo, nothing happens; the value of the nested property is not set. Is it possible to iterate through a HashMap, and let the user update its values? I am quite new to Struts, and have spent a lot of time trying to get this to work, but no luck. Any help will be appreciated!

Setting values of nested collection
Hi all I have a problem with setting the values on a hierarchy of nested properties. I have an ActionForm which has a property A of type HashMap. A is keyed on Strings, and each value of A is a Collection (ArrayList). This collection contains objects of type B. I am trying to iterate through the keys A, and for each key, iterate through the corresponding value (which is an ArrayList of B objects), i.e. I am trying to do 2 levels of iteration. The I want to display a property of B and let the user change it. I am able to display the properties of object B on the screen. However, for some reason the tag doesn't work - the textbox is there, but the input does not populate the form. The following is what I am trying to do. The problem is that when I enter a new value for foo, nothing happens; the value of the nested property is not set. Is it possible to iterate through a HashMap, and let the user update its values?

Unable to post to struts mailing list
Hi Wendy I really apologise to be sending you mail directly. I have been trying to post on the Struts list for 2 days, but for some reason I cannot manage to do it. I am registered, and I receive all the postings but mine just won't show up. I am sending to [EMAIL PROTECTED] I need to post a question as I am quite stuck, but am having no luck, and can't find any guidelines on the site. Am I doing something wrong? Many thanks!

Today I tried to deploy a .war file to my production web server which runs HP-UX. When it unpacks the war and tries to deploy the webapp, it complains: 13:29:34,070 - ERROR org.apache.struts.validator.ValidatorPlugIn - JAR entry org/apache/commons/validator/resources/validator_1_1_3.dtd not found in /opt/hpws/tomcat/webapps/benauth-test/WEB-INF/lib/commons-validator.jar java.io.FileNotFoundException: JAR entry org/apache/commons/validator/resources/validator_1_1_3.dtd not found in /opt/hpws/tomcat/webapps/benauth-test/WEB-INF/lib/commons-validator.jar I can do jar -tvf on that .jar file, and the tld appears to be where it belongs. Right where the error says it isn't. I'm not having any problems on my Windows 2000 development box with the same code, although I use the Ant install/reload tasks to deploy the "loose" files, I don't make the .war file until I'm ready to go to the production server. However, I can't click on any of the .war files that come with 1.2.4 and launch WinZip. It says, "Failed to load Main-Class manifest attribute from c:\jakarta\jakarta-struts-1.2.4\lib\commons-validator.jar". Every one of them does the same thing. Thinking that maybe I got a corrupted .zip file when I downloaded 1.2.4, I tried again but that didn't help, I still can't "open" the .jar files with WinZip. I don't know enough about jar/zip archives to guess, but something is preventing java on HP-UX from reading the commons-validator.jar file. Has anyone seen this before? What could be wrong?
