如何配置JBoss来修剪JSP生成的其他空格？

Question

Getting lots of additional whitespace in the html output, looks like its because of the JSP tags =/

I saw this referenced somewhere:

<init-param>
  <param-name>trimSpaces</param-name>
  <param-value>true</param-value>
</init-param>

That should put it in web.xml , I tried that but that didn't seem to work. Maybe I'm not putting it in the right node. Or maybe theres another way to do this.

Thanks

I dont have the CATALINA_HOME var set anywhere.

Answer 1

The mentioned <init-param> should be added to the "jsp" servlet in $CATALINA_HOME/conf/web.xml . Is this what you tried?

(EDIT: $CATALINA_HOME was just a way to designate the root of Tomcat and that the modification had to be done in Tomcat, not in the WEB-ING/web.xml of your webapp. Anyhow, for JBoss which is embedding Tomcat , and depending on the version you are using, you'll find the mentioned file here: $JBOSS_HOME/server/default/deploy/jbossweb-tomcat55.sar/conf/web.xml . Here again, $JBOSS_HOME is the root of your JBoss installation, it may not be set as environment variable.)

Answer 2

After some digging around, i found the procedure for JBoss AS 7. If anyone is interested: in your standalone.xml, find the section

<subsystem xmlns="urn:jboss:domain:web:  ... >

And add this directive:

<configuration>
    <jsp-configuration trim-spaces="true" />
</configuration>

Here are other attributes you may use
