Spring form errors with multiple identical forms on the same page -

-
i printing arbitrary number of identical forms on page using spring's <form:form tag, , need way distinguish between them, because form errors of 1 form printed on forms. currently identical forms bound same, single backing object. works fine, because user can submit 1 form @ time. i using spring validation validate form fields. when 1 of fields has error (let's 'name' empty) error message printed under 'name' field of forms. obviously, need way allow spring distinguish between forms, how? some example code: this spring webflow definition creates clientformbacking object client forms. , submits form post bindandvalidate method, calls validator. <webflow:var name="clientformbacking" class="com.example.clientformbacking"/> <webflow:view-state id="list" view="clients" model="clientformbacking"> <webflow:on-entry> <webflow:evaluate expression="contextparamete...

c++ - Rounding a 3D point relative to a plane -

i have plane class holds n normal , q point on plane. have point p lies on plane. how go rounding p nearest unit on plane. snapping cursor 3d grid grid can rotating plane. image explain: red current point. green rounded point i'm trying get. probably easiest way achieve taking plane define rotated , shifted coordinate system. allows construct matrices transforming point in global coordinates plane coordinates , back. once have this, can transform point plane coordinates, perform rounding/projection in trivial manner, , convert world coordinates. of course, problem underspecified way pose question: transformation need has 6 degrees of freedom, plane equation yields 3 constraints. need add more information: location of origin within plane, , rotation of grid around plane normal. personally, start deriving plane description in parametric form: xvec = alpha*direction1 + beta*direction2 + x0 of course, such description contains 9 variables (three vectors), c...

java - Extending the automatically generated JPA controller (Netbeans 7.x) -

-
netbeans 7.x offers possibility generate entities (pojos) existing relational database (ex: customerentity, orderentity, etc.) also, generates automatically controller each entity (ex: customerjpacontroller, orderjpacontroller, etc.). the generated controllers contains many ready-to-use methods (findall, create, delete, etc.). advantage using controllers' generator possibility recreate/update them once entity (or table) modified (adding new constraints, new fields, etc.). unlike "partial class" concept offered .net, not possible extend these controllers user-defined methods in separate classes. what suggest (in terms of best practices or design patterns) take advantage of these automatically generated controllers? i use generated controller classes in self-created dao classes.
