We experienced two issues with User Application v4.5 running on Tomcat.
The first issue has been mentioned quite a few times on the forums and @ncisrael provided a fix for. This is the issue of Compatibility Mode in Internet Explorer where the Header Portlet does not show.
The second issue was related to JQuery calls and appeared to be caused by the load timing of the page and what the client had cached. The result was often an annoying popup TypeError: $(...).tabs is not a function.
Both of these issues required a single fix, which was to alter the Headers that Tomcat sent to the client.
The first step is to create a com/domain/service/CacheControlFilter.java file:
package com.domain.service;
import javax.servlet.*;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.util.Date;
public class CacheControlFilter implements Filter
{
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException
{
HttpServletResponse resp = (HttpServletResponse) response;
/*
* Force all filtered items to not cache with revalidation
*/
resp.setHeader("Expires", "Tue, 03 Jul 2001 06:00:00 GMT");
resp.setDateHeader("Last-Modified", new Date().getTime());
resp.setHeader("Cache-Control", "no-store, no-cache, must-revalidate, max-age=0, post-check=0, pre-check=0");
resp.setHeader("Pragma", "no-cache");
/*
* Force IE Compatibility mode fix
*/
resp.setHeader("X-UA-Compatible", "IE=edge");
/*
* Send the headers
*/
chain.doFilter(request, response);
}
public void destroy()
{
}
public void init(FilterConfig arg0) throws ServletException
{
}
}
/*
< filter>
< filter-name>SetCacheControl< /filter-name>
< filter-class>com.domain.service.CacheControlFilter< /filter-class>
< /filter>
< filter-mapping>
< filter-name>SetCacheControl< /filter-name>
< url-pattern>/*< /url-pattern>
< /filter-mapping>
*/
Next, grab servlet-api.jar from the /opt/netiq/idm/apps/tomcat/lib/ directory as this will be required to build the java file.
We use bash scripts to simplify building of the java file to a class and bundling it into a jar using JDK 8.
#!/bin/sh
export JARPREFIX=lib-cachecontrol
export JAVALIBS=`pwd`/CLASSPATH
jars=( servlet-api.jar )
jars_count=${#jars[@]}
index=0
while [ "$index" -lt "$jars_count" ]
do
export CLASSPATH=${CLASSPATH}:${JAVALIBS}/${jars[index]}
((index++))
done
rm -f ${JARPREFIX}.jar
find ${JARPREFIX}.src -type f -iname *.class -exec rm -f '{}' \;
echo "Manifest-Version: 1.0">MANIFEST.MF
echo "Created-By: 1.8.0 (Oracle)">>MANIFEST.MF
echo "Author: address@domain.com - `date` - ${JARPREFIX}">>MANIFEST.MF
echo "Implementation-Version: 2.00">>MANIFEST.MF
cd ${JARPREFIX}.src
javac com/domain/service/*.java
jar -cvfm ../${JARPREFIX}.jar ../MANIFEST.MF com/domain/service/*.class
cd ..
find ${JARPREFIX}.src -type f -iname *.class -exec rm -f '{}' \;
rm -f MANIFEST.MF
Copy the lib-cachecontrol.jar to the /opt/netiq/idm/apps/tomcat/lib/ directory and fix ownership (novlua) and file attributes (644).
Next, edit the /opt/netiq/idm/apps/tomcat/conf/web.xml file and add the following just above the session-config section.
< filter> < filter-name>SetCacheControl< /filter-name> < filter-class>com.domain.service.CacheControlFilter< /filter-class> < /filter> < filter-mapping> < filter-name>SetCacheControl< /filter-name> < url-pattern>/*< /url-pattern> < /filter-mapping>
Restart idmapps_tomcat_init and validate.
