OutOfMemoryError in FCKEditorTag.java StringBuffer object

[mehmood_z@…]

I have an application which uploads the document and gives a preview in the FCKeditor where the user can customize the document and re submit to the server.I am using FCKEditor tag in the JSP page to set the content that is to be displayed in the FCKeditor. But when I upload a large document of Size apprx. 3MB ,I get OutOfMemoryError in the FCKEditorTag.java which holds the content in the StringBuffer object and this gives an error.

I am working in TOMCAT 4.1,JAVA1.5,REDHAT Linux 9.1,1 GB RAM and 80 GB HardDisk.

I have attached the document which gave this error.

regards, Mehmood

I will investigate that!

I don't exactly understand what you mean by "upload"

is your document put within <FCK:editor>document content</FCK:editor> like that?

If you suffer from ​OutOfMemoryError, it might help to increase the max heap size for the JVM running your tomcat instance.

Btw, 3 MB for a HTML doc is extremely big

Here's the deal:

WinXP, JRE 1.6.0.4, Jetty 6.1.7, 1 GiB RAM
I have created a 3 MiB document and inserted a sa FCKeditor value. What happends first is an OutOfMemoryError => not enough heap space. I have increased heap space to -Xmx256m. (This is java-specific and not fckeditor-java)
It took a few seconds to create the doc and the editor instance. So far so good. The browser takes now forever to load the document. It consumes upto 140 MiB of RAM, 90 % CPU time either FF2 or IE6, I killed the process after 5 min.

So this is a browser memory/JS issue.

Closing as WFM

Additionally, I have profiled the request and the produced page has 5 MiB and the browser loads perfectly but the js takes forever.

Hi devs,

If the jsp tag for generating the fckeditor doesn't contain the in-memory objects to handle the content of the editor, then its fine.

[Michael Osipov]

You may specify the content (value) with

<FCK:editor value="..." /> or <FCK:editor><jsp:attribute name="value">some huge text</jsp:attribute></FCK:editor>

The JSP tag is perfectly capable handling several megabytes of HTML data, the editor isn't

Replying to mosipov:

You may specify the content (value) with

<FCK:editor value="..." /> or <FCK:editor><jsp:attribute name="value">some huge text</jsp:attribute></FCK:editor>

The JSP tag is perfectly capable handling several megabytes of HTML data, the editor isn't

this applies for the upcoming version 2.4

Thanks for the reply and I know that JSP tag is perfectly capable of handling huge HTML , just now I got reminded that I posted this bug long before where the content in the FCKeditorTag was handled by StringBuffer and that has also been fixed by writing directly to the out stream.I dont know why this got re-opened!!

[Michael Osipov]

Great I could help, stay tuned for 2.4

[Mehmood]

cool thanks
