ApplicationServletEnvironment is no longer configured in war deployments

[pnoe]

Hi,
I am trying to upgrade a spring boot web mvc 3.5.8 application to 4.0.0 (jdk 25, tomcat 11)
I have the configuration of posgresql in an external tomcat context.xml file :

<Parameter name="spring.datasource.url" value="jdbc:postgresql://localhost:5432/ruchesdev" />
<Parameter name="spring.datasource.username" value="postgres" />
<Parameter name="spring.datasource.password" value="postgres" />	

with spring boot 3.5.8 it works but not with spring boot 4.0.0, to make it work I am obliged to put this configuration in application.properties :

spring.datasource.url=jdbc:postgresql://localhost:5432/ruchesdev
spring.datasource.username=postgres
spring.datasource.password=postgres

The error in eclipse console is :

APPLICATION FAILED TO START
Description:
Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.
Reason: Failed to determine a suitable driver class

In fact I have the same problem with other parameters like :

<Parameter name="spring.jpa.properties.hibernate.id.db_structure_naming_strategy"
		value="single" />

Thanks for your help,

Pierre

@pnoe that is using LDAP, isn't it? Try adding spring-boot-ldap to see if that helps?

[pnoe]

No it is not using LDAP.

Complete file (and project) :

Sorry, I meant JNDI.

We can't really debug your application. Given that you claimed in another issue that things were working in 3.5.8 while they weren't, I think we'd probably need a bit more help before investigating. Can you please debug your application and check the state of the Environment. You coud inject the Environment in a bean and use a debugger to inspect its state. Check that ServletConfigPropertySource is present and its content.

The application is in production with spring boot 3.5.8.
I'll do what you suggest, thanks again for your advices.

I have activated the /env management endpoint.
On my spring boot 4.0.0 branch I have a PropertySource name: "servletContextInitParams" where I can find all the parameters of my context.xml file.

activeProfiles	[]
defaultProfiles	
0	"default"
propertySources	
0	{ name: "servletContextInitParams", properties: {…} }
1	{ name: "systemProperties", properties: {…} }
2	{ name: "systemEnvironment", properties: {…} }
3	{ name: "Config resource 'class path resource [application.properties]' via location 'optional:classpath:/'", properties: {…} }
4	{ name: "applicationInfo", properties: {…} }
5	{ name: "Management Server", properties: {…} }

Switching to my 3.5.8 branch this item is not present

activeProfiles | []
defaultProfiles |  
0 | "default"
propertySources |  
0 | { name: "systemProperties", properties: {…} }
1 | { name: "systemEnvironment", properties: {…} }
2 | { name: "Config resource 'class path resource [application.properties]' via location 'optional:classpath:/'", properties: {…} }
3 | { name: "applicationInfo", properties: {…} }
4 | { name: "Management Server", properties: {…} }
