problem with forms
HI, I have an action form, an action and a couple of jsp pages bound together in tiles. I'm trying to access a property of the action form from the jsp and get the following error generated: javax.servlet.jsp.JspException: Cannot find bean under name org.apache.struts.taglib.html.BEAN at org.apache.struts.taglib.html.SelectTag.calculateMatchValues(SelectTag.java:240) The action can access the form bean fine. What do I need to do for the jsp to pick it up? chhum - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: problem with forms
Does the JSP have a html:form tag in it that has the action attribute set to an action mapping that has the action form as the value of the 'name' parameter? Otherwise, what scope is the action form in? -Richard [EMAIL PROTECTED] wrote: HI, I have an action form, an action and a couple of jsp pages bound together in tiles.

Re: [OT] obsfucating struts web application
Hey Erik... Just curious.. would you not have these problems at the inner layers too? Let us say ... I use Hibernate to persist my objects... since I would have to use xml mapping files between classes and database tables... I can not obfuscate my business/persistent objects as well in a straight forward fashion! May be the obfuscation tool need to look for string references as wellin the same way as an advanced refactoring IDE would do... or something like that to make our life simple! :-) ~raghu On 12/9/05, [EMAIL PROTECTED] [EMAIL PROTECTED] wrote: I have used KlassMaster on distributions that contain Struts classes before, and I took your approach as I recall. I didn't obfuscate Action classes, but there was nothing important in them anyway. Also, KlassMaster has a great scripting language for getting around the problems you mention, and it knows how to edit web.xml, etc. In my opinion, it is well worth the price ($400 for a single license last time I checked).

Let us say i have a mapping that maps to a TelephoneAction in my strus-config.xml... the class name will get 'garbled' after obfuscation. When a hit is made, the struts runtime will look up the TelephoneAction class to forward the request and notices there is no class with that name anymore! Whether bytecode or sourcecode obfuscation, this problem will still persist! One solution: Use the option *not* to obfuscate classnames of action classes. But are we done? Not yet... what if we use dispatch action class? By similar logic, you should leave even your method names unobfuscated! So that isnt too good... One of my friends suggested one ways to obfuscate the action class names and methods.As a part of obfuscation process generate a file containing mappings from old names to new names. Then based on this generated file, you can write a script to work on config.xml to find and replace the unobfuscated names with those from the mappings file generated. Some amount of work, but I guess it should work. The other approach is not to obfuscate action class names and method names in them. Just do flow obfuscation on these action classes. Action classes by design would not have too much business code in them .. as they would be delegated to some business classes. Even if complex code (in terms of number of lines) does exist in them, flow obfuscation will make it difficult to read them. If they are fewer number of lines, then it may be easy to break flow obfuscation, but then in most cases the code would be so simple that it is OK that the hacker knows it ! ;-) Since rest of the classes (other than action classes) are obfuscated with out any constraints, you should be safe... at most your action classes would be broken into. May be .. you can treat your action classes like the DMZ (demilitarized zone). Dont know if some tools support all what has been written so far. If they do someone please let us know! :-) Regards, Raghu On 11/20/05, Laurie Harper [EMAIL PROTECTED] wrote: su mo wrote: Hi, I have STRUTS 1.2.7 based web application which I want to protect the decompilation of class files.

I want to mention that I am using Dispatch action with parameters attribute, so my method names and class names are clear text on the struts-config.xml A byte-code obfuscator should have no effect on the way a class runs. Unless you obfuscate at the source code level before compiling (which would cause all sorts of problems) you shouldn't need to worry about it.

Re: problem with forms
You have a trailing slash on the html:form, so the form element is closed right there and therefore not including the select.

Re: Validator and Javascript

Your best bet is to copy the static Javascript into a seperate .js file, include that in the head of your page, and turn it off in the html:javascript tag.

html:form dynamic action value
I have a html:form tag with a dynamic action value that works in one version of Struts and not in another. I'm new to Tiles and I want to do the following in one of the reusable tiles named report.jsp: html:form action=%= (String)request.getAttribute(action) % In an experiment, I took the struts-example webapp from the Struts 1.2.8 binary distributon and modified the html-link.jsp like this: % String actionValue = /html-link-submit; request.setAttribute(action, actionValue); % html:form action=%= (String)request.getAttribute(action) % This works so I go back to my application to do the same thing but doesn't work. I get the following error on the html page in the browser: [ServletException in:/tiles/report.jsp] null' I'm using a debugger and I can see that the action attribute is defined in the request context. Why the difference? Is it the struts environment? Both are running on Tomcat 5.0.28. My app uses Struts 1.1 and has this preamble in web.xml !DOCTYPE web-app PUBLIC -//Sun Microsystems, Inc.//DTD Web Application 2.2//EN http://java.sun.com/j2ee/dtds/web-app_2_2.dtd; The modified struts-example is from Struts 1.2.8 and has the same web.xml preamble as above. Would I be right in concluding that the difference is in the Struts version and that upgrading would solve my problem? My app has close to 100 pages, so before I start, can anybody offer some insight as to the root of the problem. Thanks.

Hi In your html:javascript tag set staticJavascript=false. This will remove all scripts except your validation. However you need to add a link to the generated scripts (in a .js file) in your .jsp.
