No conversation could be found with id

Hi all,

When multiple users are trying to access JasperServer to get output of JasperReport, many times given below exception occured. Can anybody help me in resolving this problem?

 

org.springframework.webflow.conversation.NoSuchConversationException: No conversation could be found with id 'C7629AB4-76C6-39D4-D46D-13D2FC95AF14' -- perhaps this conversation has ended?

Which JasperServer version are you using?

Try editing WEB-INF/jasperserver-servlet.xml and setting the "maxConversations" property of the "flowExecutorTarget" bean to -1.

Dear Lucian,

Thanks for your kind cooperation.

I am evaluating JasperServer-2.1/JasperServer-pro-2.1.

Can you explain what is "maxConversations" property of the "flowExecutorTarget" bean? How can I use it in WEB-INF/jasperserver-servlet.xml

Kindly provide modified lines of WEB-INF/jasperserver-servlet.xml file and available links of previous threads which are related to this topic.

 

Thanks and regards,

Hi Lucian,

I have a same trouble.

I already set following.

<property name="maxConversations" value="-1"/>

But, still now have same trouble.

Is there any setting?

Jasper Server version is 3.5.

 

Best regards.

Jin

Code:

    <bean id="flowExecutorTarget" class="org.springframework.webflow.config.FlowExecutorFactoryBean">        <property name="definitionLocator" ref="flowRegistry"/>        <property name="executionAttributes">                <map>                        <entry key="alwaysRedirectOnPause">                                <value type="java.lang.Boolean">false</value>                        </entry>                </map>        </property>        <property name="repositoryType" value="CONTINUATION"/>        <property name="maxConversations" value="-1"/>        <property name="maxContinuations" value="500"/>    </bean>
