Jboss Seam: Enabling Debug page on WebLogic 10.3.2 (11g)

- by Markos Fragkakis

Hi all, SKIP TO UPDATE 3 I want to enable the Seam debug page on Weblogic 10.3.2 (11g). So, I have done the following: I have the jboss-seam and jboss-seam-debug jars as dependency in both my ejb and web maven projects (both are modules of my superproject) I put this context parameter in my web.xml: <context-param> <param-name>org.jboss.seam.core.init.debug</param-name> <param-value>true</param-value> </context-param> Now, when I hit the URL of my application, I get the debug page with this exception (full stacktrace at the end of the post): Caused by java.lang.IllegalStateException with message: "No phase id bound to current thread (make sure you do not have two SeamPhaseListener instances installed)" From posts I read it seems that this is somehow related to two jars of jboss-seam or jboss-seam-debug being in the classpath. I opened my ear file and only one of each is present (in the ear) whereas the war itself has no libraries in the WEB-INF/lib. I have also read of another way to initialize debug page using the components.xml. I also tried to include the following components.xml in the WEB-INF, but it didn't work either: <?xml version="1.0" encoding="UTF-8"?> <components xmlns="http://jboss.com/products/seam/components" xmlns:core="http://jboss.com/products/seam/core" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://jboss.com/products/seam/core http://jboss.com/products/seam/core-2.2.xsd http://jboss.com/products/seam/components http://jboss.com/products/seam/components-2.2.xsd"> <core:init debug="true"/> </components> Any suggestions on what to do to enable the debug page correctly? Cheers!

They have an outer EAR project containing the inner WAR project. They discuss that this may be related to how jars end up in the projects. I use Maven, and I had set it to create "Skinny Wars", that is excluding all jar dependencies from the inner WAR project, so that it remains small in size. All its dependencies are contained in the EAR and are used by all other modules. I changed the settings of the maven-war-plugin to leave inside the war the web-specific jars (the ones mentioned in the link, like RichFaces, jboss-seam-debug, Facelets etc). However, the problem has reverted to its previous form. I now get the debug page, whatever link I press, with the initial exception. Caused by java.lang.IllegalStateException with message: "No phase id bound to current thread (make sure you do not have two SeamPhaseListener instances installed)" UPDATE 3: The structure of the application .ear is the following: application.ear |--> APP-INF | |--> classes |--> lib (all jar dependencies go here, including the WAR dependencies, EJB module dependencies) |-->META_INF | |--> application.xml | |--> data-sources.xml | |--> MANIFEST.MF | |--> weblogic.xml | |--> weblogic-application.xml |--> jboss-seam-2.2.0.GA.jar |--> myEjbModule1.jar |--> myEjbModule2.jar |--> myEjbModule3.jar |--> myEjbModule4.jar |--> myWar.war (NO libraries in WEB-INF/lib, finds everything in EAR/lib) When deploying .ear application WITHOUT debug enabled (not including the jboss-seam-debug.jar in the ear), the application is loaded correctly. When deploying WITH jboss-seam-debug.jar in the EAR (EAR/lib directory), the application does not appear, but ONLY the debug page with the following exception (stacktrace at the end): Exception during request processing: Caused by java.lang.IllegalStateException with message: "No phase id bound to current thread (make sure you do not have two SeamPhaseListener instances installed)" When "JBoss-izing" the same EAR (remove hibernate jars, which are provided by JBoss, and move all libraries from EAR/lib to EAR root), the application loads correctly. BOTH the application AND the debug page appear correctly.

Followup: Python 2.6, 3 abstract base class misunderstanding

- by Aaron

I asked a question at Python 2.6, 3 abstract base class misunderstanding. My problem was that python abstract base classes didn't work quite the way I expected them to. There was some discussion in the comments about why I would want to use ABCs at all, and Alex Martelli provided an excellent answer on why my use didn't work and how to accomplish what I wanted. Here I'd like to address why one might want to use ABCs, and show my test code implementation based on Alex's answer. tl;dr: Code after the 16th paragraph. In the discussion on the original post, statements were made along the lines that you don't need ABCs in Python, and that ABCs don't do anything and are therefore not real classes; they're merely interface definitions. An abstract base class is just a tool in your tool box. It's a design tool that's been around for many years, and a programming tool that is explicitly available in many programming languages. It can be implemented manually in languages that don't provide it. An ABC is always a real class, even when it doesn't do anything but define an interface, because specifying the interface is what an ABC does. If that was all an ABC could do, that would be enough reason to have it in your toolbox, but in Python and some other languages they can do more. The basic reason to use an ABC is when you have a number of classes that all do the same thing (have the same interface) but do it differently, and you want to guarantee that that complete interface is implemented in all objects. A user of your classes can rely on the interface being completely implemented in all classes. You can maintain this guarantee manually. Over time you may succeed. Or you might forget something. Before Python had ABCs you could guarantee it semi-manually, by throwing NotImplementedError in all the base class's interface methods; you must implement these methods in derived classes. This is only a partial solution, because you can still instantiate such a base class. A more complete solution is to use ABCs as provided in Python 2.6 and above. Template methods and other wrinkles and patterns are ideas whose implementation can be made easier with full-citizen ABCs. Another idea in the comments was that Python doesn't need ABCs (understood as a class that only defines an interface) because it has multiple inheritance. The implied reference there seems to be Java and its single inheritance. In Java you "get around" single inheritance by inheriting from one or more interfaces. Java uses the word "interface" in two ways. A "Java interface" is a class with method signatures but no implementations. The methods are the interface's "interface" in the more general, non-Java sense of the word. Yes, Python has multiple inheritance, so you don't need Java-like "interfaces" (ABCs) merely to provide sets of interface methods to a class. But that's not the only reason in software development to use ABCs. Most generally, you use an ABC to specify an interface (set of methods) that will likely be implemented differently in different derived classes, yet that all derived classes must have. Additionally, there may be no sensible default implementation for the base class to provide. Finally, even an ABC with almost no interface is still useful. We use something like it when we have multiple except clauses for a try. Many exceptions have exactly the same interface, with only two differences: the exception's string value, and the actual class of the exception. In many exception clauses we use nothing about the exception except its class to decide what to do; catching one type of exception we do one thing, and another except clause catching a different exception does another thing. According to the exception module's doc page, BaseException is not intended to be derived by any user defined exceptions. If ABCs had been a first class Python concept from the beginning, it's easy to imagine BaseException being specified as an ABC. But enough of that. Here's some 2.6 code that demonstrates how to use ABCs, and how to specify a list-like ABC. Examples are run in ipython, which I like much better than the python shell for day to day work; I only wish it was available for python3. Your basic 2.6 ABC: from abc import ABCMeta, abstractmethod class Super(): __metaclass__ = ABCMeta @abstractmethod def method1(self): pass Test it (in ipython, python shell would be similar): In [2]: a = Super() --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /home/aaron/projects/test/<ipython console> in <module>() TypeError: Can't instantiate abstract class Super with abstract methods method1 Notice the end of the last line, where the TypeError exception tells us that method1 has not been implemented ("abstract methods method1"). That was the method designated as @abstractmethod in the preceding code. Create a subclass that inherits Super, implement method1 in the subclass and you're done. My problem, which caused me to ask the original question, was how to specify an ABC that itself defines a list interface. My naive solution was to make an ABC as above, and in the inheritance parentheses say (list). My assumption was that the class would still be abstract (can't instantiate it), and would be a list. That was wrong; inheriting from list made the class concrete, despite the abstract bits in the class definition. Alex suggested inheriting from collections.MutableSequence, which is abstract (and so doesn't make the class concrete) and list-like. I used collections.Sequence, which is also abstract but has a shorter interface and so was quicker to implement. First, Super derived from Sequence, with nothing extra: from abc import abstractmethod from collections import Sequence class Super(Sequence): pass Test it: In [6]: a = Super() --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /home/aaron/projects/test/<ipython console> in <module>() TypeError: Can't instantiate abstract class Super with abstract methods __getitem__, __len__ We can't instantiate it. A list-like full-citizen ABC; yea! Again, notice in the last line that TypeError tells us why we can't instantiate it: __getitem__ and __len__ are abstract methods. They come from collections.Sequence. But, I want a bunch of subclasses that all act like immutable lists (which collections.Sequence essentially is), and that have their own implementations of my added interface methods. In particular, I don't want to implement my own list code, Python already did that for me. So first, let's implement the missing Sequence methods, in terms of Python's list type, so that all subclasses act as lists (Sequences). First let's see the signatures of the missing abstract methods: In [12]: help(Sequence.__getitem__) Help on method __getitem__ in module _abcoll: __getitem__(self, index) unbound _abcoll.Sequence method (END) In [14]: help(Sequence.__len__) Help on method __len__ in module _abcoll: __len__(self) unbound _abcoll.Sequence method (END) __getitem__ takes an index, and __len__ takes nothing. And the implementation (so far) is: from abc import abstractmethod from collections import Sequence class Super(Sequence): # Gives us a list member for ABC methods to use. def __init__(self): self._list = [] # Abstract method in Sequence, implemented in terms of list. def __getitem__(self, index): return self._list.__getitem__(index) # Abstract method in Sequence, implemented in terms of list. def __len__(self): return self._list.__len__() # Not required. Makes printing behave like a list. def __repr__(self): return self._list.__repr__() Test it: In [34]: a = Super() In [35]: a Out[35]: [] In [36]: print a [] In [37]: len(a) Out[37]: 0 In [38]: a[0] --------------------------------------------------------------------------- IndexError Traceback (most recent call last) /home/aaron/projects/test/<ipython console> in <module>() /home/aaron/projects/test/test.py in __getitem__(self, index) 10 # Abstract method in Sequence, implemented in terms of list. 11 def __getitem__(self, index): ---> 12 return self._list.__getitem__(index) 13 14 # Abstract method in Sequence, implemented in terms of list. IndexError: list index out of range Just like a list. It's not abstract (for the moment) because we implemented both of Sequence's abstract methods. Now I want to add my bit of interface, which will be abstract in Super and therefore required to implement in any subclasses. And we'll cut to the chase and add subclasses that inherit from our ABC Super. from abc import abstractmethod from collections import Sequence class Super(Sequence): # Gives us a list member for ABC methods to use. def __init__(self): self._list = [] # Abstract method in Sequence, implemented in terms of list. def __getitem__(self, index): return self._list.__getitem__(index) # Abstract method in Sequence, implemented in terms of list. def __len__(self): return self._list.__len__() # Not required. Makes printing behave like a list. def __repr__(self): return self._list.__repr__() @abstractmethod def method1(): pass class Sub0(Super): pass class Sub1(Super): def __init__(self): self._list = [1, 2, 3] def method1(self): return [x**2 for x in self._list] def method2(self): return [x/2.0 for x in self._list] class Sub2(Super): def __init__(self): self._list = [10, 20, 30, 40] def method1(self): return [x+2 for x in self._list] We've added a new abstract method to Super, method1. This makes Super abstract again. A new class Sub0 which inherits from Super but does not implement method1, so it's also an ABC. Two new classes Sub1 and Sub2, which both inherit from Super. They both implement method1 from Super, so they're not abstract. Both implementations of method1 are different. Sub1 and Sub2 also both initialize themselves differently; in real life they might initialize themselves wildly differently. So you have two subclasses which both "is a" Super (they both implement Super's required interface) although their implementations are different. Also remember that Super, although an ABC, provides four non-abstract methods. So Super provides two things to subclasses: an implementation of collections.Sequence, and an additional abstract interface (the one abstract method) that subclasses must implement. Also, class Sub1 implements an additional method, method2, which is not part of Super's interface. Sub1 "is a" Super, but it also has additional capabilities. Test it: In [52]: a = Super() --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /home/aaron/projects/test/<ipython console> in <module>() TypeError: Can't instantiate abstract class Super with abstract methods method1 In [53]: a = Sub0() --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /home/aaron/projects/test/<ipython console> in <module>() TypeError: Can't instantiate abstract class Sub0 with abstract methods method1 In [54]: a = Sub1() In [55]: a Out[55]: [1, 2, 3] In [56]: b = Sub2() In [57]: b Out[57]: [10, 20, 30, 40] In [58]: print a, b [1, 2, 3] [10, 20, 30, 40] In [59]: a, b Out[59]: ([1, 2, 3], [10, 20, 30, 40]) In [60]: a.method1() Out[60]: [1, 4, 9] In [61]: b.method1() Out[61]: [12, 22, 32, 42] In [62]: a.method2() Out[62]: [0.5, 1.0, 1.5] [63]: a[:2] Out[63]: [1, 2] In [64]: a[0] = 5 --------------------------------------------------------------------------- TypeError Traceback (most recent call last) /home/aaron/projects/test/<ipython console> in <module>() TypeError: 'Sub1' object does not support item assignment Super and Sub0 are abstract and can't be instantiated (lines 52 and 53). Sub1 and Sub2 are concrete and have an immutable Sequence interface (54 through 59). Sub1 and Sub2 are instantiated differently, and their method1 implementations are different (60, 61). Sub1 includes an additional method2, beyond what's required by Super (62). Any concrete Super acts like a list/Sequence (63). A collections.Sequence is immutable (64). Finally, a wart: In [65]: a._list Out[65]: [1, 2, 3] In [66]: a._list = [] In [67]: a Out[67]: [] Super._list is spelled with a single underscore. Double underscore would have protected it from this last bit, but would have broken the implementation of methods in subclasses. Not sure why; I think because double underscore is private, and private means private. So ultimately this whole scheme relies on a gentleman's agreement not to reach in and muck with Super._list directly, as in line 65 above. Would love to know if there's a safer way to do that.

When I use multi_subst as start rule both files (f1 and f2) are parsed correctly; When I use machine_subst as start rule file f1 parse correctly, while file f2 fails, producing the error: “Parsing failed stopped at: || newDebt := loanammount-paidammount || price := purchasePrice + overhead + bb” When I use predicate as start symbol, file f3 parse correctly, but file f4 yields the error: “ “Parsing failed stopped at: & yy : NAT” Can anyone help with the grammar, please? It appears there are problems with the grammar that I have so far been unable to spot.

Modify PHP Search Script to Handle Multiple Entries For a Single Input

- by Thomas

I need to modify a php search script so that it can handle multiple entries for a single field. The search engine is designed for a real estate website. The current search form allows users to search for houses by selecting a single neighborhood from a dropdown menu. Instead of a dropdown menu, I would like to use a list of checkboxes so that the the user can search for houses in multiple neighborhoods at one time. I have converted all of the dropdown menu items into checkboxes on the HTML side but the PHP script only searches for houses in the last checkbox selected. For example, if I selected: 'Dallas' 'Boston' 'New York' the search engine will only search for houses in New York. Im new to PHP, so I am a little at a loss as to how to modify this script to handle the behavior I have described: <?php require_once(dirname(__FILE__).'/extra_search_fields.php'); //Add Widget for configurable search. add_action('plugins_loaded',array('DB_CustomSearch_Widget','init'));

Content Container Overlaps Menu?

- by Harold

I'm currently working on a Joomla template using CSS divs. I have a header set up with our logo image in a div floated to the left, an adspace floated to the right, and the menu bar on the bottom. My content is divided into three div columns that are contained in "container.": the left column is floated left, the center is not floated, and the right is floated to the right. The problem is the "container" for the three content divs is overlapping the menu, as you can see in this image: http://www.ndpstudentcouncil.org/images/shot1.png Here's the HTML code: > <body> <div id="backdrop"> <div > id="wrapper"> <div id="header"> > <div id="topimage"> </div> > <div id="adspace1"><jdoc:include > type="modules" name="Ad Space #1" /> > This will be the location for our > "newsflash" items. </div> > > <div id="ddtopmenubar" > class="mattblackmenu"> > <ul> > <li><a href="http://www.ndpstudentcouncil.org">Home</a></li> > <li><a href="http://www.dynamicdrive.com/new.htm" rel="ddsubmenu1">DHTML</a></li> > <li><a href="http://www.dynamicdrive.com/style/" > rel="ddsubmenu2">CSS</a></li> > <li><a href="http://www.dynamicdrive.com/forums/">Forums</a></li> > <li><a href="http://tools.dynamicdrive.com/" > rel="ddsubmenu3">Web Tools</a></li> > </ul> > <script type="text/javascript" src="js/ddlevelsmenu.js"> > ddlevelsmenu.setup("ddtopmenubar", "topbar") > //ddlevelsmenu.setup("mainmenuid", > "topbar|sidebar") > </script> > <ul id="ddsubmenu1" class="ddsubmenustyle"> > <li><a href="#">Item 1a</a></li> > <li><a href="#">Item 2a</a></li> > <li><a href="#">Item Folder 3a</a> > <ul> > <li><a href="#">Sub Item 3.1a</a></li> > </ul> > </li> > <li><a href="#">Item 4a</a></li> > <li><a href="#">Item Folder 5a</a> > <ul> > <li><a href="#">Sub Item 5.1a</a></li> > <li><a href="#">Item Folder 5.2a</a> > <ul> > <li><a href="#">Sub Item 5.2.1a</a></li> > <li><a href="#">Sub Item 5.2.2a</a></li> > </ul> > </li> > </ul> > </a> > </li> > <li><a href="#">Item 6a</a></li> > </ul> </div> </div> > <div id="container"> <script language="javascript"> > matchHeight=function(){ > var divs,contDivs,maxHeight,divHeight,d; > // get all <div> elements in the document > divs=document.getElementsByTagName('div'); > contDivs=[]; > // initialize maximum height value > maxHeight=0; > // iterate over all <div> elements in the document > for(var i=0;i<divs.length;i++){ > // make collection with <div> elements with class attribute > 'container' > if(/\bcontainer\b/.test(divs[i].className)){ > d=divs[i]; > contDivs[contDivs.length]=d; > // determine height for <div> element > if(d.offsetHeight){ > divHeight=d.offsetHeight; > } > else if(d.style.pixelHeight){ > divHeight=d.style.pixelHeight; > } > // calculate maximum height > maxHeight=Math.max(maxHeight,divHeight); > } > } > // assign maximum height value to all of container <div> elements > for(var i=0;i<contDivs.length;i++){ > contDivs[i].style.height=maxHeight; > } > } > // execute function when page loads > window.onload=function(){ > if(document.getElementsByTagName){ > matchHeight(); > } > } > </script> <div id="left"> > <jdoc:include type="modules" name="left" /> </div> <div > id="middle"> > <jdoc:include type="component" /> </div> <div id="right"> > <jdoc:include type="modules" name="right" /> > </div> > </div> > <div id="footer" class="clear"><jdoc:include > type="modules" name="footer" /> > © 2010 NDP Student Council<br > />Website Development Subcommitee > </div> </div> </div> </body> The CSS: > #backdrop { width:100%; height:100%; background: #FFFFFF > url(../images/gradient.jpg) repeat-x; > } > > #wrapper { margin:auto; width:95%; height:95%; border-right:thick solid > black; border-bottom:thick solid > black; border-top:thick solid black; > border-left:thick solid black; > background-color:white; } > > #header { height:131px; width:100%; background-color: #FFFFFF; > border-bottom:thick solid black; } > > #topimage { float:left; height:131px; width:63%; > background-image: > url("../images/ndps2.png"); > background-repeat:no-repeat; } > > #adspace1 { float:right; width:27%; height:131px; } > > #container { clear:both; } > #left{ width:20%; float:left; padding:5px; text-align:center; } > > #middle{ width:60%; padding:5px; text-align:center; } > > #right{ float:right; width:20%; padding:5px; text-align:right; } > #footer { border-top:thick solid black; width:100%; > text-align:center; } .clear { > clear:both; } Here is the CSS for the menu itself, which is from DynamicDrive.com: > .mattblackmenu ul{ margin: 0; padding: > 0; font: bold 12px Verdana; > list-style-type: none; border-bottom: > 1px solid gray; background: #414141; > overflow: hidden; width: 100%; > clear:both; } > > .mattblackmenu li{ display: inline; > margin: 0; } > > .mattblackmenu li a{ float: left; > display: block; text-decoration: none; > margin: 0; padding: 6px 8px; /*padding > inside each tab*/ border-right: 1px > solid white; /*right divider between > tabs*/ color: white; background: > #414141; Thanks for the help!

Asp.NET custom templated datalist throws argument out of range (index) on button press

- by MrTortoise

I have a class BaseTemplate public abstract class BaseTemplate : ITemplate This adds the controls, and provides abstract methods to implement in the inheriting class. The inheriting class then adds its html according to its data source and manages the data binding. This all works fine - I get the control appearing with properly parsed html. The problem is that the base class adds controls into the template that have their own CommandName arguments; the idea is that the class that implements the custom templated dataList will provide the logic of setting the Selected and Edit Indexes. This class also manages the data binding, etc. It sets all of the templates on the datalist in the Init method (which was another cause of this exception). The exception gets thrown when I hit one of these buttons - I have tried hooking up both their click and command events everywhere in case this was the problem. I have also ensured that their command names do not match any of the system ones. The stack trace does not include any references to my methods or objects which is why I am so stuck. It is the most unhelpful message I can imagine. The really frustrating thing is that I cannot get a breakpoint to fire - i.e. the problem is happening after I click the button, but before and of my code can execute. The last time this exception happened was when I had this code in a user control and was assigning the templates to the datalist in the PageLoad. I moved these into init to fix that problem; however, this is a problem that was there then and I have no idea what is causing it let alone how to solve it (and index out of range doesn't really help without knowing what index.)

Can someone help me with this Java Chess game please?

- by Chris Edwards

Hey guys, Please can someone have a look at this code and let me know whether I am on the right track with the "check_somefigure_move"s and the "check_black/white_promotion"s please?

Header Guard Issues - Getting Swallowed Alive

- by gjnave

I'm totally at wit's end: I can't figure out how my dependency issues. I've read countless posts and blogs and reworked my code so many times that I can't even remember what almost worked and what didnt. I continually get not only redefinition errors, but class not defined errors. I rework the header guards and remove some errors simply to find others. I somehow got everything down to one error but then even that got broke while trying to fix it. Would you please help me figure out the problem? card.cpp #include <iostream> #include <cctype> #include "card.h" using namespace std; // ====DECL====== Card::Card() { abilities = 0; flavorText = 0; keywords = 0;

Questions about TinyMCE. Or suggestions on a compariable product.

- by chobo2

Hi I am using jquery 1.3.2 and asp.net mvc 1.0. Originally I was using some other rich html editor but I ran into one major problem when a user pasted in text from open office or MS office it would bring along tons of styling junk. If a user like wrote one sentence what was like 25 characters and pasted that into my current html editor the count would 25,000 characters and I don't want to store all that junk( I can't afford to). So tinyMCE seems to not have this problem. However I got some questions. It seems if you want to use for commercial use(what my site is but currently is not making very much at this time) you need to get a commercial license. However it does not say if it is free or if it will cost money. I am assuming it means that you will have to pay but I would like to confirm this. So do you have to pay for a license to use tinyMCe if your using it for commercial use? (Yes/ No) ------------------ Answer the following questions if you said "no" to the first question ----------- So would I use the jQuery package then or is it better to use the other versions? What is this .net compressor zip for? Do I need it? I only want a few of the buttons(like bold,font size) can I remove the other buttons? It seems to display a word count. Can it be changed to character count? ----------------- Answer the following question if you said "yes" to the first question -------- Is there a rich html editor that is free for commercial use and preferably for jquery that can remove the junk that office programs seem to bring along? This is a test to show how much formatting gets made. • One • Two • Three The above text when copied into my current rich html editor will have all this code with it. <meta http-equiv="Content-Type" content="text/html; charset=utf-8"><meta name="ProgId" content="Word.Document"><meta name="Generator" content="Microsoft Word 12"><meta name="Originator" content="Microsoft Word 12"><link rel="File-List" href="file:///C:%5CUsers%5Cchobo2%5CAppData%5CLocal%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_filelist.xml"><link rel="themeData" href="file:///C:%5CUsers%5Cchobo2%5CAppData%5CLocal%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_themedata.thmx"><link rel="colorSchemeMapping" href="file:///C:%5CUsers%5Cchobo2%5CAppData%5CLocal%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_colorschememapping.xml"><style>  </style> <p class="MsoNormal">This is a test to show <b style="">how</b> much formatting gets made.</p> <p class="MsoListParagraphCxSpFirst" style="text-indent: -0.25in;"><span style="font-family: Symbol;"><span style="">·<span style="font: 7pt "Times New Roman";">         </span></span></span>One</p> <p class="MsoListParagraphCxSpMiddle" style="text-indent: -0.25in;"><span style="font-family: Symbol;"><span style="">·<span style="font: 7pt "Times New Roman";">         </span></span></span>Two</p> <p class="MsoListParagraphCxSpMiddle" style="text-indent: -0.25in;"><span style="font-family: Symbol;"><span style="">·<span style="font: 7pt "Times New Roman";">         </span></span></span>Three</p> <p class="MsoListParagraphCxSpLast"><o:p> </o:p></p>

The rich html textbox is some jquery plugin that I use and has basic stuff like bold,underline and etc. Now I am anticipating that people will maybe write something in word and then copy and paste it into my textbox. However I limit the number of characters a person can have. This is a test to show how much formatting gets made. • One • Two • Three So I wrote that above(it does not copy to well into here). Basically it is a line of text and "how" is bold and the "one,two,three" are a bullet list. Word says it is 70 characters long with spacing. However when I post this data from my textbox to my server I get a length back of 24577 characters. so I checked what was being sent and I get this <meta http-equiv="Content-Type" content="text/html; charset=utf-8"><meta name="ProgId" content="Word.Document"><meta name="Generator" content="Microsoft Word 12"><meta name="Originator" content="Microsoft Word 12"><link rel="File-List" href="file:///C:%5CUsers%5Cchobo2%5CAppData%5CLocal%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_filelist.xml"><link rel="themeData" href="file:///C:%5CUsers%5Cchobo2%5CAppData%5CLocal%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_themedata.thmx"><link rel="colorSchemeMapping" href="file:///C:%5CUsers%5Cchobo2%5CAppData%5CLocal%5CTemp%5Cmsohtmlclip1%5C01%5Cclip_colorschememapping.xml"><style>  </style> <p class="MsoNormal">This is a test to show <b style="">how</b> much formatting gets made.</p> <p class="MsoListParagraphCxSpFirst" style="text-indent: -0.25in;"><span style="font-family: Symbol;"><span style="">·<span style="font: 7pt "Times New Roman";">         </span></span></span>One</p> <p class="MsoListParagraphCxSpMiddle" style="text-indent: -0.25in;"><span style="font-family: Symbol;"><span style="">·<span style="font: 7pt "Times New Roman";">         </span></span></span>Two</p> <p class="MsoListParagraphCxSpMiddle" style="text-indent: -0.25in;"><span style="font-family: Symbol;"><span style="">·<span style="font: 7pt "Times New Roman";">         </span></span></span>Three</p> <p class="MsoListParagraphCxSpLast"><o:p> </o:p></p> Is there something I can use to get rid of all this stuff?
