I just created a Spring MVC project in STS 3.3.0.RELEASE and just changed the default<org.springframework-version>3.1.1.RELEASE</org.springframework-version> to <org.springframework-version>3.2.1.RELEASE</org.springframework-version>, and Eclipse throws errors (see screenshot below). Any clue on how to remove these errors (perhaps the top one is the culprit)
Solved - http://www.captaindebug.com/2013/03/creating-spring-32-mvc-web-app.html#.Uf7V-WTbrus - quoting the author - Now, I could have used the fix outlined in my previous blog; however, the Guys at Spring have been busy and now the solution to this problem is to simply upgrade to Spring version 3.2.2-RELEASE

I haven't been able to figure out what I'm missing here.
I've installed Tomcat and can spin it up fine. (Glassfish too, in my efforts, but I had removed it when I took the screenshot.)
So now I want to hook my project up to the Tomcat instance so I can have Netbeans deploy it for me automatically.
I right-click on my project, go down to Properties. In Project Properties I select 'Run' and go to the drop down to select my server. Only, there's no servers.
Why is it not showing up here? Am I going about this all wrong?
Thanks in advance for any help!
Other potentially useful notes:
* Using Gradle (for my first time)
* Using Spring Boot (for my first time)
* On Windows 10 (don't hate me, I don't love it either)
I was chasing the wrong problem. Spring-boot provides an embedded server so I had no need to install and provide my own.
My real problem was that I had dependencies declared for jpa, postgresql, etc. that I hadn't configured in application.properties. When I tried to run, I'd get an error saying "a problem occurred starting process /path/to/my/jdk/java.exe". I couldn't figure what was going on and, looking around, I saw the issue mentioned in my question about the server.
The solution was to simply comment out the dependencies in my build.gradle until I was ready for them. After I got my PostgreSQL DB set up and added the configureation to application.properties, I was able to un-comment them and it's working great.
I am quite new to Spring, now trying out Roo. I am following documentation from http://docs.spring.io/spring-roo/docs/2.0.0.M1/reference/html/
I was able to create the entity classes and fields, perform tests as well. Now when I run
roo> web mvc setup
it creates a few files in \config, \validatin, \html\converter but then produces undo create ... for the same files & folders. At the end it says
ERROR: GlobalSearch.java class doesn't exists or has been deleted.
I am running Windows 10 64 bit, STS 3.8 Release, Roo 2.0.0.M2, Maven 3.3.9, Jdk 1.8
Googling this as well as searching in StackOverflow gave just one slightly relevant result without resolution Spring Roo: 'web mvc setup' fails with 'display name required'.
In fact I have been facing many issues, each step of the way and googling my way through, so it has been a very painful experience so far, so any help is greatly appreciated.
I was using a separately downloaded roo (v 2)for this.
Alternatively I used STS and added roo (v 1.3.1RC1) extension thru Help>Dashboard and opened roo console in STS (Window>Show view>Roo shell), was able to run the commands for mvc web setup and mvc web all --package ~.web and generate required files!
But don't know why the separate roo console wouldn't work.
Thanks for all who viewed and tried to help.
First you need to create DAO layer:
repository jpa --all --package ~.repository
This will generate GlobalSearch.java in repository package.
I have a Maven jersey-quickstart-webapp Project I am developing in Eclipse. The project is a JERSEY REST backend with angularjs javascript frontend.
I would like to know how to check what version of EclipseLink my project is using.
Where can I find this property? I've searched high and low but I can't find it - I know that I did stumble across it before, so it definitely exists....
This question is trying to get to the bottom of the following question I posed months ago about a problem with eclipselink and Jersey REST, that still hasn't been fixed: Class not found when using JAX-RS with Eclipse and Glassfish
This should be fixed with jersey 2.22.1 and eclipselink 2.6.1, but I think somewhere in my setup, eclipselink 2.6.0 is still hanging around and screwing the whole thing up. Highly frustrating!
I know that eclipselink is being used in this project, because the following code returns 2.6.1 when the project is running. However, previously I saw that even though this was saying 2.6.1, that the eclipselink configuration somewhere(I can't remember where - doh!) was still saying version 2.6.0.
//This helps us tell what version of eclipse link we are using
Class<?> myClass = Class.forName("org.eclipse.persistence.Version");
Method myMethod = myClass.getMethod("getVersion");
String version = myMethod.invoke(null).toString();
System.out.println("version = " + version);
Here is what the Maven dependency hierarchy looks like - as you can see it has no eclipselink stuff in there:
All help highly appreciated...
The eclipselink you're running is provided by the Glassfish server. Look in the glassfish/modules directory and find the org.eclipse.persistence.core.jar file. Inside it will be a readme.html. Open that and the version of eclipselink that is installed in Glassfish will be there.
Mine says, for glassfish 4 (somewhat old) is:
<B>EclipseLink 2.5 Read Me</B>
Duplicated! Refer this
There is a static class and static method to get this information.

AbstractSessionLog.getLog().log(SessionLog.INFO, DatabaseLogin.getVersion());
I am trying to run my spring boot application (via Run As -> Spring Boot Application) in a tomcat8 container on STS and I am receiving these errors:

I have searched around for this quite a bit and have found little to guide me in figuring out what the problem is. After going through the spring boot code in the debugger I see that the object named "instance" referenced in the TomcatWebSocketContainerCustomizer.addListener() uses reflection to retrieve a handle to it. This object is associated with the tomcat 7.0.53 jar ($HOME/.m2/repository/org/apache/tomcat/tomcat-catalina/7.0.53/tomcat-catalina-7.0.53.jar). I do not see this in any of my maven dependencies and have tried several techniques to force it to tomcat 8.0.20, nothing seems to work.
After banging my head for a while I started looking at the run configuration for the project in STS (via Run As -> Run Configurations). I found that the Source tab shows tomcat 7.0.53 above version 8.0.20 along with several dependencies that aren't referenced in maven. I am at a loss on where these values come from and not sure how to edit it. For some reason when I try to manually delete these legacy jar files STS doesn't allow me to delete any of them.
Does anyone have an idea of where these dependencies may be coming from and how I can remove them?
They do reference my $HOME/.m2/path/to/tomcat-catalina/<version> dir, so I could simply remove them from my .m2 and theoretically it may work but I'd rather not do this if I don't have to.
I am using spring boot 1.2.x and all of them have this problem.
thanks.
I've got two ideas that you might try.
1) It is possible, that this may be manifestation of this bug in STS 3.6.4: https://issuetracker.springsource.com/browse/STS-4085
The depencies you aren't expecting to see may be coming from the maven 'test' scope. (The bug explicitly mentions 'srt/test' but the same happens with jar dependencies). You can verify whether this bug is the cause by using the regular "Run As Java Application" on your main class.
If that works, then it is almost certainly this bug. If it also fails with a similar error then its something else... then try:
2) You must be getting the unwanted tomcat version from somewhere, probably indirectly as dependency of something else.
Try using the m2e 'dependency hierarchy' to find where it came from like so:
open pom.xml
Click the 'Dependency Hierarchy' tab.
Type 'tomcat' in the 'Filter' box.
I finally figured it out.
In my $WORKSPACE/.metadata/.plugins/org.eclipse.m2e.core/workspacestate.properties it lists all poms, jars and wars from my workspace build with the maven plugin. I noticed that a pom in the file points to the exact version tomcat that is being loaded in my spring boot project. Once I deleted these projects from my STS I can successfully launch the spring boot app :-)
When I re-import the maven projects back to STS the error occurs again, then disappears when I remove them.
These projects have no connection to the project that I am trying to launch. Therefore I think the bug is in m2e.
I'll file a bug and update this post when it is complete.
thanks #Kris for working through it with me.
my primary attempt is to build a CRUD app using Roo, following the example here:
https://www.icts.uiowa.edu/confluence/display/ICTSit/Spring+Roo+Tutorial
I am using Roo 1.2.5, Maven 3.1.1, and Spring 3.2.6 on JRE7.
This has been the best tutorial I have found so far. If anyone has a better example, please share!
However, when I execute the project in my Tomcat environment things still break. The primary error from there is:
HTTP Status 500 -
type Exception report
message
description The server encountered an internal error () that prevented it from fulfilling this request.
exception
java.lang.NoClassDefFoundError: org/springframework/util/MimeType
I have built multiple projects using Roo over the past few days, either from this tutorial or 10 others that all start with the reverse engineer command, and all give me the same type of a NoClassDefFoundError, either with this class or another. I understand this means that my pom.xml is more than likely incorrect, but I am hoping this is an issue with my configuration rather than something all Roo developers have simply accepted as manual maintenance.
Any advice would be tremendous... is it possible that the version of Roo combined with Spring and Maven I am using is simply buggy? I would love to use this framework/toolkit, but am nearing the point where manually writing the scaffolding by hand may be more straightforward.
.... UPDATE:
By adding the following dependency manually, I was able to run the project. However, I want to leave the question open to see if anyone further knows whether this missing jar is a known bug given the version of Spring Roo I am using, or otherwise:
<dependency>
<groupId>commons-fileupload</groupId>
<artifactId>commons-fileupload</artifactId>
<version>1.2.2</version>
</dependency>
Thanks!
The best examples are those included in Roo: clinic.roo, pizzashop.roo, etc
Just run Roo and execute any of them as follows:
/_/ |_|\____/\____/ 1.2.4.RELEASE [rev 75337cf]
Welcome to Spring Roo. For assistance press TAB or type "hint" then hit ENTER.
roo> script --file clinic.roo
On the other side, the reference doc is a good starting point: http://docs.spring.io/spring-roo/reference/html/
Finally, about java.lang.NoClassDefFoundError: org/springframework/util/MimeType note MimeType class was included in Spring 4 and Roo sets up your project for Spring 3, so you must customize the pom.xml as needed.
