Done some pretty extensive research on this the last few days. Our
application doesn't work at all on our test and production servers, because
of the dreaded "invalid constant length" error.
We have the following setup:
- jre-6u16 for linux
- Suse Linux
- JBoss 5.0.1 with embedded tomcat
- Compiles using java 1.6, tried both 1.5 and 1.6 as target compatibility
I have verified that there is excactly ONE javassist.jar within my jboss
directory, and the version of that file is 3.9.0.GA.
I still get javassist crashes on several of my smaller components, like the
one below. I'm going crazy over this, especially because it indicates to
everyone else that our big investment in T5 may have been a really stupid
move.
Just reported this to let you know that this problem DOES occur when there
is only one javassist.jar, and it is causing major problems for us.
Example of crashing component:
@IncludeJavaScriptLibrary( { "context:/script/tiny_mce/tiny_mce.js" })
public class TinyMceEditor {
public static final String MODE_EXACT = "exact";
public static final String MODE_TEXTAREAS = "textareas";
@Inject
private UrlProvider urlProvider;
@Environmental
private RenderSupport renderSupport;
@Parameter(defaultPrefix = BindingConstants.LITERAL, value =
MODE_TEXTAREAS)
private String mode;
/**
* If mode=exact, attach editor to these elements
*/
@Parameter
private ClientElement[] elements;
void initEditor(MarkupWriter writer) {
// We can't use renderSupport to add script, tinyMCE refuses to accept
// scripts added this way. It needs inline script. Script tag written
// manually below.
String jsonString = getJSON();
writer.element("script", "type", "text/javascript");
writer.writeRaw(String.format("tinyMCE.init(%s)", jsonString));
writer.end();
}
/**
* Make sure editor content is saved to form field before Tapestry AJAX
* submits.
*/
void patchZoneForms() {
renderSupport.addScript("document.forms[0].observe(Tapestry.FORM_PROCESS_SUBMIT_EVENT,
function() {tinyMCE.triggerSave()});");
}
/**
* Get JSON config for tinyMCE object. Configured to view one simple
toolbar.
*
* @return
*/
private String getJSON() {
JSONObject json = new JSONObject();
json.put("mode", mode);
json.put("theme", "advanced");
addElementList(json);
json.put("theme_advanced_toolbar_location", "top");
json.put("theme_advanced_toolbar_align", "left");
json.put("theme_advanced_buttons1",
"bold,italic,underline,bullist,numlist,undo,redo,outdent,indent,fontsizeselect");
json.put("theme_advanced_buttons2", "");
json.put("theme_advanced_buttons3", "");
json.put("content_css",
urlProvider.getContextAssetUrl("/css/tinymce.css"));
return json.toString();
}
private void addElementList(JSONObject json) {
if (MODE_EXACT.equals(mode)) {
if (elements != null && elements.length > 0) {
StringBuffer elementsString = new StringBuffer();
for (int i = 0; i < elements.length; i++) {
ClientElement currentElement = elements[i];
FrontendTools.appendCommaSeparated(currentElement.getClientId(),
elementsString);
}
json.put("elements", elementsString);
}
else {
throw new IllegalArgumentException("Exact mode specified, but no
elements");
}
}
}
void afterRender(MarkupWriter writer) {
initEditor(writer);
patchZoneForms();
}
}
