How to change memory and other JVM settings for STS

[janwen]

So much!
1.Our projects developed with myeclipse and using svn manage source code.I check out project from our svn repo,and change .project and .classpaht .settings/.... to the STS format.
2.I try to use tomcat6 deploy web projects(more than 2 at same time),and they depends each other.I can not deploy success.We do not use maven.
3.I try to deploy only one web project,It success,but i can not figure out why more than 2 projects deploy at same time fail.

4.I try to replace tomcat with tcServer,fail too.

I upload some capture to clear my quesion.

Hey!

1. Why do you need to change .project and .classpath settings? STS is using nothing special here, just the standard Eclipse settings. What exactly did you change there? Do those projects contain anything special for myeclipse?

2. + 3. What problem do you see exactly? Can you maybe attach a small sample project that illustrates the problem?

4. You don't need to work with tc Server when using STS, you can continue to use Tomcat, if you want. But aside of that, can you provide more details what exactly goes wrong when you try to deploy your project to tc Server?

Can see those images i uploaded?
I compared those files:.project,.classpath and .setting/ files with STS project,They are different from the web project that create from STS.
Our source structure in svn repository like the image show:
myeclipse_svn.jpg
This is .project file from myclipse web project

The key issue is(I guess）,STS can not recognise the myeclipse web project,but i manually change the project facets,they STS can not deploy the myeclipse web app.

I spend another day to transform the myeclipse projects to STS,remain fail.

[Martin Lippert]

Sorry, but I edited your post and removed the big font and the red color. That didn't really help here...

[Martin Lippert]

And can you attach a small sample project (the version before you edited anything manually in order to make it fit into STS)? That would be great. Thanks!!!

[janwen]

I can not upload the whole project files.That is our business project.I upload some myeclipse project metadata files instead.

[Martin Lippert]

Hey!

Hard to say from just the metadata, because I guess you transformed it into Eclipse WTP style, right?
(something like this I guess: http://nileshk.com/2005/11/03/migrat...se-to-wtp.html)

I am wondering if the problem is STS-specific or also related to standard Eclipse webtools, in which case we might find additional useful information on their forums/mailing lists. Did you try that?

[janwen]

Thanks,Martin.
To use STS(I love it),I create two projects to solve the issue.There are two projects,one is java project,another is web project.see my attachment file.I remove the dependency log4j for the size limit of the forum.
I add the java project(Java1) to the web project web1 build path(project),and then deploy the project to tomcat6.x.There is just one jsp file named index.jsp in the web1.After starting tomcat,I go into http://www.qianpin.com/web1/ and get the exception:

org.apache.jasper.JasperException: javax.servlet.ServletException: java.lang.NoClassDefFoundError: com/qianpin/java/test/HelloWorld

The HelloWorld is in the java project.Could you see my test? thanks.
P.S No sts users encounter my issue? I google and search in the forum both,no relate information.

[janwen]

I google this page:http://stackoverflow.com/questions/1...r-java-project
My issue is as same as that.After i deploy my webproject,tomcat can not find the java project classes.

[Martin Lippert]

Hey!

I looked at your example, thanks for posting the details and the sample. Here is what I did to make this work:

- in the web1 project, I opened the project preferences, selected "Deployment Assembly" and added the java1 project as a project to that list.

- in the java1 project, I also opened the project preferences, selected "Deployment Assembly" and added the log4j jar file (as build path entry) to that list.

After that I don't see any exceptions anymore.

HTH,
Martin
