My application is a servlet, spring 4 application where the spring jar is in the tomcat lib.
Freemarker jar is in WEB-INF/lib.
I am getting this error when starting the server
java.lang.ClassNotFoundException: freemarker.template.TemplateHashModelEx
This error disappears when I move the freemarker jar to tomcat lib directory.
It appears to me that spring 4 webmvc jar which contains Configurer class is unable to see WEB-INF/lib freemarker jar. I do not understand why freemarker jar in WEB-INF/lib folder is not visible to spring jar in tomcat lib folder.
What may I do to resolve this situation.
My spring configuration is as follows
<bean id="freemarkerConfiguration" class="org.springframework.ui.freemarker.FreeMarkerConfigurationFactoryBean">
<!--Turn this off to always load via SpringTemplateLoader-->
<property name="preferFileSystemAccess" value="false"></property>
<property name="templateLoaderPath" value="classpath:/"></property>
</bean>
<bean id="freemarkerConfigurer" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
<property name="configuration" ref="freemarkerConfiguration" />
</bean>
add the following code in pom.xml
<dependency>
<groupId>org.freemarker</groupId>
<artifactId>freemarker-gae</artifactId>
<version>2.3.18</version>
</dependency>
This works for me.
I've had similar issues before and I've solved it.
Environment：Idea 、 Maven
Open File->Project Structure->Artifacts
Right click on the Project Library in the "Available Elements" to put in output root(WEB-INF/lib).
Restart tomcat and you'll see the problem was solved.

There are a JAR A and JAR B, both have messages.properties in classpath /
And there is WAR C, which has dependencies on JAR A and JAR B.
And when I start WAR C I can only get i18n message from JAR A or JAR B.
So, how can Spring support multiple messages.properties files in classpath?
BTW, WAR C is a spring boot project, and spring.messages.basename=messages
Problem solved.
According to this question Does Spring MessageSource Support Multiple Class Path?
have to ditch ResourceBundleMessageSource and write a custom implementation of MessageSource (most likely by subclassing AbstractMessageSource) which uses PathMatchingResourcePatternResolver to locate the various resources and expose them via the MessageSource
I make a copy of ReloadableResourceBundleMessageSource and write the code by this guide and problem solved.
Yes, Spring supports loading multiple Properties. But properties should be unique. If we have same properties in the two Properties Files then the file which will be loaded later will override the previous Properties from previous file.
For example, if the Properties file from JAR A has two properties {USERNAME, PASSWORD} and JAR B Properties file also has the same two properties then you'll get {USERNAME, PASSWORD} from the file which is loading later.
You can use wildcard to import all the Property Files with same name on your classpath.
In Spring you can mention different Properties files in the form of Array as follows:
<context:property-placeholder
location="classpath:war.properties,
classpath*:message.properties"
ignore-unresolvable="true"/>
or
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:war.properties</value>
<value>classpath*:message.properties</value>
</list>
</property>
<property name="ignoreUnresolvablePlaceholders" value="true"/>
</bean>
I wrote a Maven plugin which instantiates a Spring context. I want to be able to configure the Spring context using a properties file in the project classpath. In the plugin context XML I have:
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<value>classpath:configurator.properties</value>
</property>
</bean>
When I run the proper plugin goal in the Maven project using my plugin, Spring can't read the configurator.properties file from the target/classes folder.
How should I configure my mojo to allow Spring running in my plugin to read the properties file from the project classpath?
Warning: newbie alert!
I'm in early days of learning Spring and am trying to get my first app up and running which will simply read some data from a DB and display it.
I'm using SpringSource Tool Suite 2.8.0.RELEASE. I've created a new Spring MVC project and want to read some data from a local MySQL DB.
I wrote a simple DAO class:
package com.blah.blah;
import org.springframework.jdbc.core.support.JdbcDaoSuppo rt;
public class MyDAO extends JdbcDaoSupport {
I've added this to the pom.xml file:
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-jdbc</artifactId>
<version>${org.springframework-version}</version>
</dependency>
I've added this to the root-context.xml (is this the right config file to update?):
<bean id="myDataSource"
class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost:3306/dbname" />
<property name="username" value="root" />
<property name="password" value="mypw" />
</bean>
<bean id="jdbcTemplate"
class="org.springframework.jdbc.core.JdbcTemplate" >
<constructor-arg ref="myDataSource"></constructor-arg>
</bean>
<bean id="parentDAO"
class="org.springframework.jdbc.core.support.JdbcD aoSupport">
<property name="dataSource" ref="myDataSource"></property>
</bean>
When I right-click on the project and select Debug As > Debug On Server I get the error:
24-Mar-2012 16:13:42 org.apache.catalina.core.StandardContext listenerStart
SEVERE: Exception sending context initialized event to listener instance of
class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.CannotLoadBeanClassException:
Cannot find class [org.springframework.jdbc.datasource.DriverManagerDataSource]
for bean with name 'myDataSource' defined in ServletContext resource
[/WEB-INF/spring/root-context.xml]; nested exception is
java.lang.ClassNotFoundException: org.springframework.jdbc.datasource.DriverManagerDataSource
I've been looking at this for a while and can't figure out what I'm doing wrong. I've found the folder where the app is deployed to (C:\Program Files\springsource\vfabric-tc-server-developer-2.6.1.RELEASE\spring-insight-instance\wtpwebapps\MyAppName\WEB-INF\lib on my machine) and the lib folder contains spring-jdbc-3.1.0.RELEASE.jar and when I open it, I can see the DriverManagerDataSource class file so I don't know why I'm getting the error above.
Any advice greatly appreciated.
Check that the Spring libraries are in the classpath so they are available for the server.
I had the same jar file included in the project twice. Removed one and it worked.
I had the same problem in Eclipse and creating a new workspace solved this problem.
I had added required jar source instead of release. Strange but changing that to release version fixed this problem.
I am trying to move a working spring WAR to OSGI environment (in glassfish 3.1 and blueprint, spring 3.0.5).
The application loads properties file from disk, like this:
<bean id="myProperties" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="${my_conf}/my.properties"/>
<property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE"/>
</bean>
I see in debugger that ${my_conf}/my.properties is translated to the existing path (c:\conf\my.properties)
I use the property jms.url defined in my.properties in the next bean declaration
<amq:broker useJmx="false" persistent="false" brokerName="embeddedbroker">
<amq:transportConnectors>
<amq:transportConnector uri="tcp://${jms.url}"/>
<amq:transportConnector uri="vm://embeddedbroker" />
</amq:transportConnectors>
</amq:broker>
And in deployment I get an exception "Could not resolve placeholder ${jms.url}"
Why it fails? Is there another way to load properties from file on disk?
thank you
Since its an OSGI environment, you will need spring-osgi-core jar added to your application. Take a look at this link to configure property-placeholder for OSGI framework.
It isn't a solution, but an explanation of my problem.
The problem is related to this bug in spring 3 and osgi.
I had to open spring logs to debug level to understand it.
I'm trying to set a bean property like this:
<bean id="threadImport" class="com.foo.bat.util.ThreadImport" singleton="false">
<property name="mailSender" ref="mailSender"/>
<property name="parseConfFile" value="classpath:parse/import.xml" />
<property name="logFilename" value="/tmp/import.log" />
but none of files are found. What's the classpath for my deployed application? May I set it on any weblogic xml descriptors? Which is the best way to place and locate files used on spring applications?
I am using:
<bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:foobar-config.properties" />
</bean>
The properties file is either location at the root of my test source folder so JUnit has a test-specific config available and in production, we have added a classpath entry to Weblogic pointing to the configuration folder. You can do that in the setDomainEnv.sh or for Managed Servers, in their configuration (web console), server start, classpath.
