Dear all,

I’m trying to port Spring’s jpetstore to MyEclipse and Maven 2

I created the following file structure:
mvn archetype:create -DgroupId=org.springframework.samples.jpetstore -DartifactId=jpetstore -DarchetypeArtifactId=maven-archetype-webapp

and used mvn eclipse:eclipse after I edited the pom.xml

However, without “Add WebProject Capabilities”, I cannot deploy the WAR to my app server (JES8.1) <- “project deployments”

How may I get this work, thx?

Thomas,
There really isn’t a workaround here, if you want to deploy the project using MyEclipse’s deployment manager, you do need to tell MyEclispe that it’s a web project.

Is there a reason you cannot add Web Project Capabilities.

Hi,

My reason is that I need Maven2 for build and deploy for the deployers (they don’t have IDE). The developers will use MyEclipse, but the file structure must follow the one Maven2 defines, including using libraries from the Maven2 local repository

I’m a bit confused:

My reason is that I need Maven2 for build and deploy for the deployers (they don’t have IDE)

From this, I understand that you are deploying the project with Maven, however in your original post you said:

However, without “Add WebProject Capabilities”, I cannot deploy the WAR to my app server (JES8.1) <- “project deployments”

which made me think you were deploying with MYEclipse… so basically I’m just confused about a) what the problem is and b) what you are trying to do. If you can set me straight on this I’m sure we can get this working for you.

Hi,

I want to deploy the wep app using MyEclipse, but the Eclipse project should be created by Maven 2 using mvn eclipse:eclipse (it’ll override MyEclipse’s setting from time to time)

If I don’t execute “Add WebProject Capabilities”, I couldn’t get the App Server listed in the “project deployments” dialog. But If I execute “Add WebProject Capabilities”, the Eclipse project will be changed and doesn’t look the same as the one created by Maven

Without MyEclipse, to deploy, I need to:

C:\workspace\jpetstore>mvn install
…
C:\workspace\jpetstore>”C:\Program Files\netbeans-4.1\SunAppServer8.1\bin\asadmin” deploy target\jpetstore.war
Command deploy executed successfully.

Is there a way to enable deployment via both the IDE and Maven at the same time? Thx

[Riyad Kalla]

Ok, so the trick here is going to be making “Add Web Project capabilities” look identical to how Maven has setup the project. The two directories we need to care about here are the WebRoot directory (you can name this whatever you want when you add capabilities) and the Output directory (typically WebRoot/WEB-INF/classes). As long as your project resembles an exploded WAR deployment, there shouldn’t be any problems. However if your web artifacts (web.xml, struts-config, faces-config, etc. etc.) are not under the WEB-INF dir someplace and instead exist in another location outside of the “WebRoot directory, this is going to keep you from successfully adding Web Capabilities, as MyEclipse assumes these locations. People in the past have worked around this by using Sym links on Linux and Windows (yes NTFS supports real-life sym links, need to google for it).

What is the format of your project (please wrap your text in code blocks using code button below so it maintains formatting).

Hi, the following is the default Maven2 file structure

src/
+--main/
   +--java/
   +--resources/
   +--webapp/
      +--images
      +--WEB-INF <- web.xml, applicationContext.xml, struts-config.xml etc
         +--jsp <- all JSPs r stored here, and referred by the Spring/Sturts controller
target/
.classpath <- created by Maven 2's Eclipse plug-in
.project <- created by Maven 2's Eclipse plug-in
.wtpmodules <- created by Maven 2's Eclipse plug-in

The WEB-INF/lib is created by Maven via the local repository; the Eclipse’s .classpath file contains:

where M2_REPO is a variable in the workspace that points to Maven’s local repository

This should be doable, add Web Capabilities:
1) Make your Web Root dir: /webapp
2) Make your source dir: /java
** After the project is created, add /resources as another source dir, it will be copied into the root of your /classes dir
3) After you finish the adding of web caps, edit the Java Build Path and change the output dir to /webapp/WEB-INF/classes
**4) You might need to create an empty /lib dir
5) Be sure to setup the deployment settings to deploy external JARs and/or USer Libraries depending on how you have the classpath for the project setup.
6) Go add all your JARs to your build path

Now try and deploy the project to Tomcat or whatever app server you are using.

Almost worked, but the JARs under M2_REPO cannot be copied to WEB-INF/lib

I included them in the Java Build Path/Order and Export, but I have an empty WEB-INF/lib dir

That should be fine, as long as you configured the deployment settings to deploy the other types of JARs you ahve added, all should be right with the world. Are you not seeing it working?

[twhphan]

I couldn’t find the “deployment settings” to “deploy the other types of JARs I have added”. Is there a checkbox in the UI, where?

In my packaged archive (WAR), I couldn’t see WEB-INF/lib there after I unzipped it

Thx

[Riyad Kalla]

My appologies, you can navigate to Window > Preferences > MyEclipse > J2EE Project > Web Project > Deployment tab

If you would like to change the settings only for a specific project and not for the entire workspace, open up your project properties and go to MyEclipse-Web and Deployment tab and you can change them there.

[twhphan]

I checked “Jar dependent projects and place in the ‘lib’ directory”

but still not working, what still should I set

Sorry for asking this… This is my first MyEclipse deployment… Many thx

[Riyad Kalla]

Change that setting back to “Smart deployment”, what you should have checked is all the checkboxes below. Please note that we are trying to deploy the JARs in your build path, this has nothing to do with deploying “dependnt projects”.

If all those checkboxes *are* already checked, then I need to ask how you are adding those JARs to your build path. Are they external JARs? User libraries? what?

[twhphan]

After I checked all the checkboxes, I got

Deployment is out of date due to changes in the underlying project contents. You’ll need to manually ‘Redeploy’ the project to update the deployed archive

I tried to press the “Redeploy” button, but it also give me the same message

Thx
