Abstractmethoderror Using Uribuilder on Jax-Rs

AbstractMethodError using UriBuilder on JAX-RS

AbstractMethodError are thrown when an application tries to call an abstract method.

uri is an abstract method in UriBuilder, so you need an implementation of this. This method (with String parameter) is from version 2.0 of JAX-RS specification.

You're trying to use JAX-RS 2.0 with Jersey 1.*. Instead, you need to use Jersey 2.* that implements JAX-RS 2.0 and contains an implementation to uri method.

In your pom.xml you may remove these dependencies:

<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-bundle</artifactId>
    <version>1.19</version>
</dependency>
<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-server</artifactId>
    <version>1.19</version>
</dependency>
<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-core</artifactId>
    <version>1.19</version>
</dependency>
<dependency>
    <groupId>javax.ws.rs</groupId>
    <artifactId>javax.ws.rs-api</artifactId>
    <version>2.0-m12</version>
</dependency>

And use these dependencies:

<dependency>
    <groupId>org.glassfish.jersey.core</groupId>
    <artifactId>jersey-server</artifactId>
    <version>2.17</version>
</dependency>
<dependency>
    <groupId>org.glassfish.jersey.containers</groupId>
    <artifactId>jersey-container-servlet-core</artifactId>
    <version>2.17</version>
</dependency>

Using this, uri method is implemented in JerseyUriBuilder class from jersey-common.

EDIT:

You need to change, in your web.xml, servlet com.sun.jersey.spi.container.servlet.ServletContainer to org.glassfish.jersey.servlet.ServletContainer and init-param from com.sun.jersey.config.property.packages to jersey.config.server.provider.packages

java.lang.AbstractMethodError: javax.ws.rs.core.UriBuilder.uri

You're using both Jersey 1 & 2 (Jersey 1 is an explicit dependency, Jersey 2 is a transitive dependency of jersey-test-framework-provider-jdk-http) and that's not possible - so the classloader is picking up the wrong URIBuilder class.

The Jersey dependencies in group com.sun.jersey are all Jersey version 1.
Jersey version 2 uses the group org.glassfish.jersey.

You have both in your Maven dependencies which is causing this problem.

If possible only use Jersey 2.

java.lang.AbstractMethodError: javax.ws.rs.core.UriBuilder.uri(Ljava/lang/String;)Ljavax/ws/rs/core/UriBuilder;

Although I don't know why it used to work with Tomcat 6 and started giving the above exception when upgraded to Tomcat 8, however, removed:

javaee-api 7.0

jar and added:

<dependency> 
    <groupId>javax.ws.rs</groupId> 
    <artifactId>jsr311-api</artifactId> 
    <version>1.1.1</version> 
</dependency>

The above exception went away. In order to have the consistency bet. Jersey client and server jars, used:

jersey-server 1.10

jar but received this error:

java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer

When put the:

jersey-server 1.9

back, exception went away and the REST services started working again.

Please note, if your application, needs other jars from javaee-api, add each jar individually; looks like javaee-api package jar can't co-exist with Jersey 1.

AbstractMethodError: javax.ws.rs.core.UriBuilder.uri in REST, EJB Application

You have multiple dependencies in your classpath that contains javax.ws.rs.core.UriBuilder, two of JAX-RS 1.1:

<dependency>
    <groupId>javax.ws.rs</groupId>
    <artifactId>jsr311-api</artifactId>
    <version>1.1.1</version>
</dependency>

---

<dependency>
    <groupId>com.sun.jersey</groupId>
    <artifactId>jersey-core</artifactId>
    <version>1.18</version>
</dependency>

And one of JAX-RS 2.0:

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>7.0</version>
</dependency>

Since JAX-RS 2.0 is from Java EE 7, probably you need downgrade javaee-api to version 6, using like this:

<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0</version>
</dependency>

Other way is upgrade Jersey version, like in this answer: AbstractMethodError using UriBuilder on JAX-RS

In runtime UriBuilder#uri(String) is called, so you need to verify the dependencies in the servlet container.

AbstractMethodError with URI Builder

You might have got your issue fixed, but actual problem is

The uri method is an abstract method in UriBuilder from version 2.0 of JAX-RS specification.

You're trying to use JAX-RS 2.0 with Jersey 1.*. Instead, you need to use Jersey 2.* that implements JAX-RS 2.0 and contains implementation of uri method.
