set value in JSP

Hello,

I'm using FCKeditor with JSP. Can I fill in the textbox without using javascript?

I can use this:

<FCK:editor instanceName="autre_info">
<jsp:attribute name="value">Content</jsp:attribute>
</FCK:editor>

But my content comes from a database, so I want to write this:

<FCK:editor instanceName="autre_info">
<jsp:attribute name="value"><%=Content%></jsp:attribute>
</FCK:editor>

but then I get a compilation error : cannot find symbol "content".

Any clues?

Provide the stack trace. FCKeditor.Java is a JavaScript implemenation. You can provide a value from any source you want.

Re: set value in JSP

This is the error:

/administration/modarticle.jsp:268: cannot find symbol
symbol  : variable scontenu
location: class _jsp._administration._modarticle__jsp._CauchoFragment
        out.print((scontenu));
                   ^
/administration/modarticle.jsp:268: illegal start of type
        out.print((scontenu));
                  ^
2 errors

This is my code: (That I simplified because content comes from database)

<%String scontenu= "hello";%>
<FCK:editor instanceName="autre_info"><jsp:attribute name="value"><%=scontenu%></jsp:attribute></FCK:editor>

Re: set value in JSP

As you can see, Resin tells you that you have a type problem.

I just did a quick test and following works as expected:

<jsp:scriptlet>
   <![CDATA[String content = "mosipov, This is some <strong>sample text </strong>. You are using <a href=\"http://www.fckeditor.net\">FCKeditor</a>.";]]>   
   </jsp:scriptlet>
      <h1>FCKeditor - JSP - Sample 2</h1>
      This sample displays a normal HTML form with an FCKeditor with full 
      features enabled.<br />
      This sample uses the FCKeditor Taglib: this method is preferred to 
      <a href="sample01.jsp">the API version</a><br />
      All other sample pages will use this method.
      <hr />
      <form action="sampleposteddata.jsp" method="post" target="_blank">
         <FCK:editor instanceName="EditorDefault">
            <jsp:attribute name="value"><%=content %>
            </jsp:attribute>
         </FCK:editor>
         <br />
         <input type="submit" value="Submit" />
      </form>
   </body>

The problem must be within your code.

Although there is an better and easier way.

Put your string in the request when you come from a servlet and simply do:

<FCK:editor instanceName="autre_info" value="${content}" />

Re: set value in JSP

Thank you for your answer. That solved my problem. Here's how I did it:

<%! static String content = ""; %> (That is what I was not using: the declarative line to set the String)

<% content = getFromDB(); %>

<FCK:editor instanceName="autre_info">
     <jsp:attribute name="value"><%=content %></jsp:attribute>
</FCK:editor>

Thanks

Re: set value in JSP

it must be something special with Resin as far as I can see.

You can reduce your code by doing:

<%! static String content = ""; %> (That is what I was not using: the declarative line to set the String)
<% content = getFromDB(); request.setAttribute("content",content);%>
<FCK:editor instanceName="autre_info" value="${content}"/>
