Yeah, I've seen this too. This bug will prevent you from loading a JMX file that has one or more HTTP Cookie Manager elements in it. When you get this error on a particular JMX file you will not be able to load it until you remove the HTTP Cookie Manager element from the JMX file manually or you make a code change to the JMeter source.
To remove the HTTP Cookie Manager from the JMX file open the JMX file in a text editor, find any sections in the file that look something like the below snippit and remove those sections from the file. <!-- JMX file snippit --> <node> <testelement class="org.apache.jmeter.protocol.http.control.CookieManager"> <property xml:space="preserve" propType="org.apache.jmeter.testelement.property.StringProperty" name="TestElement.gui_class">org.apache.jmeter.protocol.http.gui.CookiePanel</property> <property xml:space="preserve" propType="org.apache.jmeter.testelement.property.StringProperty" name="TestElement.test_class">org.apache.jmeter.protocol.http.control.CookieManager</property> <property xml:space="preserve" propType="org.apache.jmeter.testelement.property.StringProperty" name="TestElement.name">HTTP Cookie Manager</property> <property xml:space="preserve" propType="org.apache.jmeter.testelement.property.BooleanProperty" name="CookieManager.clearEachIteration">false</property> <property xml:space="preserve" propType="org.apache.jmeter.testelement.property.BooleanProperty" name="TestElement.enabled">true</property> <collection class="java.util.ArrayList" propType="org.apache.jmeter.testelement.property.CollectionProperty" name="CookieManager.cookies"> <testelement class="org.apache.jmeter.protocol.http.control.Cookie" name="sessionid"> <property xml:space="preserve" propType="org.apache.jmeter.testelement.property.StringProperty" name="Cookie.path"/> <property xml:space="preserve" propType="org.apache.jmeter.testelement.property.StringProperty" name="TestElement.name">sessionid</property> <property xml:space="preserve" propType="org.apache.jmeter.testelement.property.BooleanProperty" name="Cookie.secure">false</property> <property xml:space="preserve" propType="org.apache.jmeter.testelement.property.StringProperty" name="Cookie.domain"/> <property xml:space="preserve" propType="org.apache.jmeter.testelement.property.StringProperty" name="Cookie.value"/> <property xml:space="preserve" propType="org.apache.jmeter.testelement.property.LongProperty" name="Cookie.expires">0</property> </testelement> </collection> </testelement> </node> <!-- JMX file snippit --> If you really need to use the HTTP Cookie Manager you can comment out the line below in CookieManager.java and rebuild. I've been using this as a workaround and it works reliably. JMeterContextService.getContext().getVariables().put(c.getName(),c.getValue()); The NullPointerException is caused by the call to getVariables() returning a null. I don't know the JMeter code base enough to submit a patch for this but if someone who knows the JMeter code base has some time you should be able to reproduce this issue using CVS HEAD if you add a HTTP Cookie Manager to a test plan, save the test plan and then try to load it. Brent -----Original Message----- From: Duncan Frostick [mailto:[EMAIL PROTECTED] Sent: Thursday, August 14, 2003 10:35 AM To: JMeter Users List Subject: Saved JMeter Test Plans not reloading Hi, This is problem I've only had with the new version, but whenever I save a test plan I've been playing with, come back to it later and then try to re open it JMeter can't do it citing an 'Unexpected error'. Namely a NullPointerException. It's getting very annoying because when I've perfected a test plan to do what I want it to, save it then go to show it to my boss later in the day, it doesn't work. Any ideas what I can do to stop this, bearing in mind I need a cookie manager?
