Error while deploying portlet with remote service

New Member Posts: 3 Join Date: 1/11/17 Recent Posts

Hello to all.

I'm using plugins sdk 6.2 with a portal 6.2 ga 5 bundled with tomcat 7.0.62

I tried to create a portlet with remote service, but when i try to deploy i get an error during the jsonws registration and i can't see it in the context paths in api/jsonws.

I followed the tutorial in the documentation.

the error is the following

Do anyone has some advice? Is it a problem of web.xml configuration?

Strangely when I tried an example found on internet:

https://sourceforge.net/p/lportal/news/2014/02/liferay-plugin-portlet-json-web-services/

https://sourceforge.net/projects/meeralferay/files/LiferayPluginPortletJSONWebServices/

I inlcuded the portlet with eclipse using new liferay plugin from eexisting source, and it works.

Are there some differences beetween liferay 6.1 and 6.2?

Thanks to all

Took 2 days to figure this out. This is somehow related to Java version. Try using Java8 for building and deploying your services. It will work. Worked for me.

A blind guess why this is happening:
Liferay is using jodd.asm5 (Check first line of your exception trace)
and I checked Jodd site https://jodd.org/download/ and they are not supporting it after Java 8. Not sure how Liferay is using that.

Hm - back in the 6.x times, there was no Java11 support at all, maximum is Java 8 AFAIK.
I understand your objection (and am wondering about it) for newer versions, but in 6.2 the recommendation to go with (max) Java8 is solid.

Thanks a lot for your answer Dhruv Pandey! By the way, I ran into this exact issue in a Liferay 7.2 instance on Java 11.
I had this configuration in the build plugin of my service pom.xml:

&nbsp;&nbsp; &nbsp;<build>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<plugins>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<plugin>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<groupid>org.apache.maven.plugins</groupid>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<artifactid>maven-compiler-plugin</artifactid>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<version>3.8.1</version>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<configuration>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<source>1.8
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<target>11</target>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;</configuration>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;</plugin>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;...
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;</plugins>
&nbsp;&nbsp; &nbsp;<build></build></build>

This was throwing the error because the Java runtime version of my artifact was set to 11...but Jodd only works when targeted for Java 8 maximum. What I did, is changed the configuration to the following:

&nbsp;&nbsp; &nbsp;<build>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<plugins>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<plugin>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<groupid>org.apache.maven.plugins</groupid>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<artifactid>maven-compiler-plugin</artifactid>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<version>3.8.1</version>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<configuration>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<source>1.8
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;<target>1.8</target>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;</configuration>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;</plugin>
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;...
&nbsp;&nbsp; &nbsp;&nbsp;&nbsp; &nbsp;</plugins>
&nbsp;&nbsp; &nbsp;<build></build></build>

After building and deploying the error was gone.
